Use of automatic blood analyzer to detect blood sugar technology research (3)

  IV.Dynamic blood glucose monitoring technology
  Because of biochemical analysis and fast blood cells analyzer and this minimally invasive technique can't or continuous dynamic detection of patients with glucose in the blood and can't get closer to the truth so, dynamic blood glucose monitoring system (CGMS) came into being dynamic spectrometry can eliminate individual differences and measuring conditions on the influence of the spectral measurement.

   Studies have think that, as a result of the pulse of the phenomenon, blood vessels in blood flow to a periodic change, blood is not transparent liquid, the light in the blood, penetrating than in the organization through small a few times, so the change may cause the pulse of near infrared spectral absorbency change, so through the dynamic spectrum record artery to maximum and filled with the arterial constriction of the most hours to spectrophotometry value, can remove the individual differences and measuring conditions on the influence of the spectral measurements, correction model prediction ability, improve the precision of the spectral measurement MiniMed company production of the United States CGMS already in June 1999, the FDA approved for listing. 

    CGMS is a minimally invasive blood glucose monitoring system, by detecting subcutaneous tissue of the liquid glucose concentration between and reflect the blood sugar level, it will continuously monitoring patient 1 day at each hour of the blood glucose levels, this instrument is only the size of a mobile phone, with microcomputer chip, there is a slight hose connection instruments and detection head, detection head into the subcutaneous tissue every 10 seconds from detector instrument to an electrical signal changes reflect blood sugar, the electric signals of every 5 minutes average conversion to blood sugar leels storage up every day can record store 288 blood sugar value the instrument and can also record and storage dine sports events such as drug use. 

    CGMS to continuous monitoring three days (72 hours) the dynamic change of blood sugar, and then the data can be downloaded to the ordinary computers, provide to the doctor diagnose evidence however, CGMS and non-invasive detection techniques of GWG2B device, accuracy also there are some problems, mainly in induced insulin hypoglycemia, these devices monitor blood glucose is not high credibility, therefore, the food and drug administration suggest not only the material and change the treatment, must first use standard of blood glucose meter checked.

    To sum up, and the technology and noninvasive technique each have advantages and disadvantages, in a long stage, two kinds of technology will complement each other, common development, but diabetes diagnosis must through

Use of automatic detection of blood analyzer blood sugar technology research(2)

     Perlong medical equipment company before study, small make up to introduce the two kind of use of automatic hematology analyzer to test the technology blood sugar analyzer development next, for everyone to continue this two other current use common blood glucose testing technology

    3.Non-invasive blood glucose testing technology
    Noninvasive blood sugar test is a kind of need not collected blood samples of blood glucose concentration measurement new technology, it will not damage the body any trauma, won't cause humoral infectious disease, use convenient in recent years, the research of this aspect has become the hot spot of the international academic, appeared far infrared spectra of near infrared spectral polarized light technology percutaneous reverse spin ion pump technology impedance measurements of principles measurement system

    The company produces the Cygnus California GlucoWatch Biographer wrist watch type blood glucose detection device, to use negative ion pump technology, through the in vitro diagnostic reagent to the analysis of the body fluids, every 10 min read a data, and can continuous record 13 h, namely 78 a blood sugar leels, the second generation of the wrist watch type blood sugar test device GlucoWatch G2 Biographer (GWG2B) for the United States in 2002 approved by FDA for adults with a prescription and 7 ~ seventeen sales, Europe also approved to enter the market.

    In recent years, domestic ShenTao ShenYaoChun also useful noninvasive blood sugar concentration to test research, and had made new progress of near infrared spectral technology in the analysis of material test has the following advantages: the area near infrared absorption coefficient is small; Apply to diffuse technology; Near infrared can in glass and quartz in penetrable; Investment and operation cost is low; Can be used for sample of qualitative, also can get high precision of quantitative results; Don't reagent, the polluting the environment; Determination very fast in a very short period of time has become a non-invasive blood glucose testing technology, the main research method.

    But li gang, etc have argued that the biological internal organization structure and its composition is complicated, the near infrared spectrum absorption area is not significant, the spectral measurements of interference factors exist, leading to the signal-to-noise ratio and measuring precision is low, especially individual difference and detection conditions light body the accuracy of measurement have great influence, floating standards law detection technology can effectively reduce the measurement environment change and background of the samples change, human physiological background is to solve the problem of the most promising changes interfere with one of the scheme

    The newly tang fei and introduces a kind of metabolic heat the whole legal noninvasive blood glucose detection technology, using temperature sensor infrared sensor humidity sensor and optical measurement device, as measured by the human body metabolism heat generation of blood flow velocity oxygen saturation, using the human body metabolic heat generation of blood glucose concentration of oxygen is for function, can work out what the blood sugar concentration

    They for metabolic heat the whole legal non-invasive blood glucose detection technology research and developed prototype medical clinic patients in the crowd and clinical trials on the patient clinical trials, and to obtain the data analysis, the blood glucose testing results and the large biochemical analyzer to obtain the result of relative coefficients reach 0.856 experiments, metabolic heat the whole legal noninvasive blood glucose testing technique is feasible although no and automatic blood analyzer research and development of the analyzer move very quickly, but this kind of percutaneous detection equipment, by many factors, to improve the accuracy of the results.

With the automatic hematology analyzer to test blood sugar technology research (1)

    Perlong medical equipment company research through the automatic hematology analyzer research, diabetes is caused by the body's lack of insulin to sugar, protein, fat metabolism disorder, the most significant change is laboratory increase in blood sugar. Automatic blood cells analyzer has many and varied, according to test the extent of the traumatic event can be divided into contact with pain type, nearly no damage blood sugar concentration detector and no wound blood sugar concentration detector. Traditional detection method in blood sugar from draw blood biochemical analysis, this belongs to the test, to the patient not only bring pain, but also easy to cause the various body fluids the spread of infectious diseases. Recent non-invasive detection technology and continuous monitoring technology of blood test new technology, this method changes the disadvantages of the traditional test methods, easy to use.

      1. The biochemical analysis method
      Traditional detecting blood sugar common method of extraction from the body vein blood or punctured patient fingers, extracting blood samples, and then blood cells fully automatic analyzer for testing, belong to the test. The methods used in the detection of early blood sugar fain armour aniline method, this method to aldehydes sugar such as glucose, half of lactose, xylose even ascorbic acid are reaction, and in the acidic environment produced in green, adjacent to a specific poor aniline glucose, and acidic solution to automation determination of the pipe with destruction, so in recent years have gradually be eliminated. The glucose oxidase (GOD) method is the most widely used blood sugar test of a kind of method, this law by other compounds in the disturbances, its principle for use of oxygen and water will glucose oxidation as glucose acid, and release hydrogen peroxide. Peroxidase in color, former sex oxygen receptors will using hydrogen peroxide decomposition for water and oxygen, and make the color of oxygen receptors for amino Ann than forest and phenol to hydrogen condensation red quinone compounds, namely Trinder reaction. Red quinone compounds the relic of glucose is proportional to the content. In recent years, application has sugar kinase (HK) method, the enzyme will conversion of glucose to glucose and phosphoric acid (G6P), as have other G6P dehydrogenase (G6PD) exists, can determine the enzyme NADP ability and measure the reduction of glucose. Realize the detection system of plasma glucose determination comparability, the clinical diagnosis and treatment has a very important value, because blood sugar test method of various instruments, in addition to making every instrument interior quality control outside, still should establish the target can be trace detection system, will build the results of inspection and target detection system comparing the result, make each detection system the results between the comparable. The world health organization recommends GOD method and HK as a method for determination of glucose, the reference standards, and get the 19 th world diabetes congress and the official website of the advisory groups WHO recognized, suggest vein plasma glucose should be as measuring and reporting of blood glucose concentration standard method. Think the test result is stable, reliable, but many times determination, need to be repeated blood, determine the results relatively long time, it is not convenient to patients, this from the body draw blood biochemical analysis belongs to the test, to the patient not only bring pain, easy to cause the various body fluids the spread of infectious diseases, exsanguinate trouble, blood use, and can't see results at that time, therefore, biochemical analysis application by certain restrictions.

      2. Fast blood sugar test
      In 1968 the first fast blood analyzer was published, in patients with fingertips a drop of blood can be to test your blood sugar, belong to the minimally invasive testing. The early detection principle for the glucose oxidase reaction than color. The enzyme to touch as enzyme oxidation of glucose glucose acid and hydrogen peroxide, and hydrogen peroxide oxidation and oxygen to accept agent produce color change, usable reflection or absorbed photometric were monitored. Has already been developed into the electrochemical analysis, through the reaction produces in the process that the current blood sugar. Fast blood glucose meter has the stable and reliable, simple operation, economic, health, especially for less need for blood glucose monitoring of patients many times, can reduce the pain from the venous blood in many times, and provide the scientific basis for rapid diagnosis. So are widely used for testing the commonly used tools bed blood sugar, and get good evaluation. But is the whole blood capillary blood endings, including plasma and red blood cells. And red blood cells contain less than plasma glucose, hollow when endings blood glucose levels should the whole blood plasma glucose levels than venous blood low about 12%, and with the peripheral blood often take with ZuZhiYe leak, make the endings are more likely to lower than venous blood glucose plasma glucose. The blood analyzer mainly by patients to clinical operation, the influence factors of the glucose levels increase, sometimes error is bigger, largely to the operator, of course, blood glucose meter itself quickly quality reliability and accuracy also have relations. According to the provisions of the operation, such as not calibration test code, save dipstick improper, not regularly with correction fluid correction, etc.; Not for the blood analyzer regularly cleaning maintenance, eliminate color system than by pollution; To the fingertips when disinfection, cannot use iodine, disinfection of alcohol to dry with fingertips to puncture; While testing blood sampling the drops of blood too little or squeeze the fingers too hard to ZuZhiYe dilute the blood and so on, its accuracy will be affected. In addition, vitamin C, bilirubin, there were internal or external blood interfering substances, some patients with high blood fat and blood is oily shape, can make the light reflecting error than color, such as by colorimetric fast blood analyzer will influence the results. Blood sugar too much or too little easy out error, but also by the electromagnetic interference. These various influence factors, limiting the blood of the analyzer result can not fast as diabetes diagnosis, can only be used for people with diabetes daily self monitoring, to ensure the accuracy of the results, should be timely calibration and quality control.

Hematology Analyzer

    Hematology analyzer, also known as blood cell analyzer, blood cell counter. This machine is widely used at all levels of hospital in China as well as around the world. It not only improves the accuracy of the experimental results, but also provides a number of experimental indexes, which play an important role in the diagnosis and differential diagnosis of the disease.    

    The hematology analyzer is a very wide range of hospital clinical laboratory instruments. The blood test blood means the common test of blood counted under the microscope, which includes red blood cells, hemoglobin, white blood cell count and its classification, platelet count, a total of 10 to projects. A patient's blood test is the most skilled, the most rapid at least 10 minutes. With the rapid development of science and technology, the automated hematology analyzer, blood cell analysis technology has changed from three sorts to five sorts since these years, and turned to the three-dimensional space from two-dimensional space, while the modern blood cell analyzers and five classification techniques use many advanced technology, such as the sheath flow technology, laser technology.

    In 1947, U.S. scientists Coulter (W.H.Coulter) invented the patented technology to count particles using a resistor. 1956 he successful applied this technology into blood cell count, the principle according to the non-conductive nature of the blood cells, blood cells suspended in the electrolyte solution to detect the resistance change caused by counting the holes, the blood count and volume determination, this method is called the resistance method or principle of Coulter. In 1962, the first blood count analyzer successfully developed in Shanghai. To the 1960s, the blood cell analyzer not only can count the blood cell, but also simultaneous determination of the HGB hemoglobin. In the 1970s, the platelet count instrument. In the 1980s, developed a classification of leukocytes (Category 3 and Category 5). In the 1990s, developed a blood cell count of red blood cells on the mesh analyzer, while five classification and the detection of immature cells are more mature and developing into blood cells analysis pipeline.

The microplate maintenance and exclude plugging holes

    The purchase of our computer microplate reader , after seven years of everyday applications, this instrument performance is stable, washing board the effect is good. But in daily work, often meet cleaning head plugging hole phenomenon. Cleaning head generally fall into two (12 needles and 8 pin cleaning head), although and medical equipment company communication, but still be a problem. The most common is 12 pin cleaning head.


      In the enzyme panels in the process of cleaning, if appear cleaning head plugging hole phenomenon, the water injection dissatisfaction or not water injection, it will directly affect the quality of cleaning, cause enzyme markers cleaning not clean, leading some enzyme markers attached to the hole wall, add after news of substrate of A and B liquid, there could be false positive results.


      Cause dissatisfaction or not water injection water injection for many reasons, but the most common is: liquid crystal or foreign sucked. Usually, we will use the following method to eliminate and maintenance:

(1) By 3 mL needles absorb a certain amount of saline or distilled water, went to jam the pinhole forcibly pressure push people, repeated several times; Also can use directly to suck ears ball playing harmonica blowing hard.

(2) Must not cleaning head toward the hard mesa pat, so as to avoid the pinhole by plugging the whole. If appear this kind of circumstance, can use pliers to pull out the pinhole even outside a little, and at the same time make the height of the pinhole remain in the same level.

(3) Due to the different products, the size of the pinhole may be different, when cleaning to adjust good cleaning head pinhole to appropriate location.

(4) Every day after washing board, all want to use distilled water flushing piping system. After the above maintenance, they can get a more satisfactory washing board effect on the daily quality of the work will have certain assurance.

Automatic biochemistry analyzer optical components maintenance

    Automaticbiochemical analyzer is a medical device company research and development of medical inspection instrument main component part of physics, chemistry, optical and the combination of the biological medicine, including the spectrophotometer, automatic biochemistry analyzer, ultraviolet, visible photometric, fluorescence photometric and so on, its structure is mainly have optical system (light path) and circuit system (circuit) two parts. To make instruments often is in good working condition, often should to the instrument for the daily maintenance and maintenance.

      1, Grating
      Grating is continuous spectrum analysis and inspection instrument happened the main dispersion components. Because of its uniform dispersion, spectral lines clear, work characteristics such as wide band, has basic replaced the prism, become the protagonist of the dispersion components. Grating is composed of many as wide space, the parallel slit of optical components, according to the diffraction of light and dry shoot the work principle. Its surface coating, have a layer of aluminum film, texture is soft, easy to scratch. Therefore, in the maintenance, repair process, gentle with, forbidden by hand or other items to wipe. Otherwise, can cause the aluminum film permanent damage. If the aluminum film on the dust and unclean thing. And you can use blows balloons will go to the blow.

     2, The collimator mirror
      The collimator is actually a piece of a concave mirror. According to the nature of the concave mirrors that is parallel to the axis of paraxial rays, via a concave mirror reflects will build up after in the focal plane and the principle of work. The collimator mirror most used spherical reflector, also have a parabolic mirror the rotation. The surface of the mirror the collimator is usually coated aluminum film, if in the visible region, in order to protect the aluminum film are not destroyed, often in the aluminum film plating outside a protective layer of silicon dioxide again, but in the ultraviolet area, to guarantee a high reflectivity, generally have no such protection layer, has no protection for a straight lens, the maintenance methods and grating the same. Banned the maintenance and repair process with hand or other hard goods to wipe.
     
      3, Cuvette
       Cuvette called than than color pool, the color, the color than cup than tanks, biochemical analysis instrument is the attachment.Cuvette in optical system than the main used for holding than color sample analysis of liquid. To get the accurate measurement results, the correct use of dish than color and the maintenance, the maintenance is especially important. In visible range, cuvette than common colorless optical glass or plastic; In the uv area commonly used quartz glass production. In addition to the color dish than with the pervious to light, also should have the strong corrosion resistance. The color of the general and instrument than the dish is the form a complete set, can't mix, otherwise, it will bring big measurement error. Check whether than color dish to meet the requirements of method is, in every color dish than the same colored solution put rules of the wavelength measurement, read out of the transmission than error should be less than . Otherwise, the error is too big, should not be used. Color used than dish, attention shall be paid to its place direction, because pervious to light after the reversing direction, the pervious to light abilities may change. Some general have the dish color than before, and to indicate the direction of the light. Cheng fang in the liquid, the fluid volume than color a little more than a cup of I / 2 can, than color appearance not sticky liquid dish or other and mud. Otherwise, the meeting because of the light reflection and refraction, seriously affect the measurement results. Measuring over, should immediately put distilled water flushing, regular inspection wall if there is residual, often to keep it clean.

      4 ,The objective, the eyepiece
      The eyepiece is optical microscope objective and major components. Optical microscope as a simple optical inspection instruments, due to its simple structure, convenient operation, in big, small and medium-sized widely used in hospital. To maintain its performance and extend its life, often need to do the maintenance.
First, the objective lens in the eyepiece, surface used every time a day or after work, need to use clean brush cleaning, or with special brush mirror wipe clean paper. If the microscope vision fuzzy, or lens on the touch dirt, oil play or finger print. Or born lens mold, born the fog, should by engineering technical personnel more serious wipe:
 
      When wiping, eyepiece, focusing on through can be broken apart is wiped. The objective for structure is complex, need special instrument calibration can be restored to the original precision, so it is strictly prohibited to decomposition is wiped. Remove the eyepiece, focusing lens, want to note the following points:
(1) The movement wants light.
(2) Remove the components relative position, relative order and the face of positive and negative of lenses etc to do or do a marker record. Prevent errors heavily.
(3) The operation environment clean and dry. When wiping: first use clean brushes or blows balloons to remove the lens on the sand and dust, to prevent dust when wiping scratch lens. Then, with a clean from the lens center began to flannelette edge for spiral one-way movement, until wipe so far. If there is oily be soiled, dirt or fingerprints etc't wipe off dirt, can use a dip in alcohol and already ether without water mixture to wipe; If there are heavier mildew spot, can the cotton dips in water calcium sulfate powder was to wipe, wipe finished, should clean the powder.

Maintenance of microplate washer sensing breakdown

        Microplate washer fault phenomena: switch on the power, the instrument not through self, rose to the top in flushing head become stuck when, no longer action display tip fault information: MECHANISM JAM CLAEN JAMTHEN-(YES), eliminate card plug place, and then press YES . 

          Analysis overhaul: microplate washer standard orifice plate position is the automatic, depend on automatic screw and light sensitive components (position sensor) provide all kinds of standard orifice plate and flushing head positioning microplate every boot, want to start self-inspection program, the orifice plate flush head position and other system for testing, once abnormalities are found, the screen shows error message mechanical system is the sensor control circuit mechanical parts not the reason caused by mechanical action usually have a mechanical parts of the card to die circuit faults sensor damage according to the fault reasons such as tips, cut off the power supply in the case, artificially hedge shampoo orifice plate position and screw wheel and so on mechanical parts inspection, its action normal detection circuit position sensor and its peripheral components also no abnormalities are found so they and the WeiXiuShang contact and the factory. 


            Maintenance experience: the machine is the fault occurred, the reason is because of long use or long-term out of service, and no to maintain, cause sensor not clean or pollution caused by machine set automatic washing machine electronic pipeline for the integration of precision instruments, more than 80% of the fault mostly concentrated in the pipeline channel electrode (sensor) and mechanical parts to this kind of instrument to the daily maintenance and repair work very necessary after each use of electrode (sensor) and pipeline for a clean; Periodically mechanical parts of a maintenance; For a long time every time the instrument a debugging maintain this to keep the instrument good performance, low breakdown has important significance in addition, when instrument once breaks down, should follow the simple to numerous CongNan to easily the principle of whom, according to the first.

History of the X-ray machines (Medical x ray machine)

    Many great achievements in science and technology, often is from a chance . In 1895, a German scientist, Wilhelm konrad rontgen in a physics experiment unexpected discovered x-rays. So far, th history of the application of X-ray in the medical field(medical X-ray machine) has been 100 years . In these years, the development of the X-ray machine has a rapid development and summarizes the main up can be classified into three main stages:

    The first stage: before in the 1970s, the tube of the x ray could be developed from fixed anode to rotate anode, from medium speed development to high speed, improved  filament materials, made the tube heat capacity of x ray more and more big, the volume is more and more small, the technology is mature. High voltage generator control mode for development by mechanical vacuum tube control into transistor in control. Imaging to increase a film feeling screen mode, the same experience too slow, middle and high speed development process, perspective and photography dose is becoming more and more little. In this stage, the characteristics can be summarized as industrial frequency 50/60 Hz, increases the feeling screen a film.

   The second stage:in the 20 years of 70-90s. Firstly, the appearance of X-ray image intensifier makes X-ray TV system to become a reality. Secondly, the development of the modern electronic computer technology, let people can store and handle images.The appearance of the DSA technologies make the frequency of high voltage generator develop from 50/60 Hz to 10 kHz.With the improvement of frequency, the volume of high voltage generator is reduced dramatically and make the pulse exposure as a reality. This phase can be summarized as DSA, high frequency silicon controlled.

   The third stage: from90 s to the present day and the stage is the most rapid development of X-ray machines. Because of the applications of high power high frequency power module , such as IG-BT, IPM, GTR and high power CMOS module makes high voltage generator th frequency of up to 20-100 kHz, into the silent era. Image collection, appear l 249 line high TV system, air ionization chamber detector array detector array is more silk, semiconductor photosensitive detector array, after four ways of abandoned the traditional increase feeling screen-film combination, completed the direct digital photography. And along with the more and more quick  processing of computer  and the processing technology of computer image is mature, real-time DSA to become a reality. This period can be summarized as silent digital age.

    With the development of science and technology in medical device field , authoritative medical X-ray machine manufacturers Perlong Medical also keep the step with The Times. Perlong Medical invests a lot of money each year for product development and upgrade and has the ability to the rapid market.

How should inspection medical devices maintenance?(2)

2. Special maintenance work
This part of the content is mainly aimed at the characteristics of the testing instrument is concerned, because each test instruments have their respective characteristics, here only introduce some typical representative respects.

(1) The photoelectric components such as light power supply, cell, photomultiplier tubes, etc in the store and work all should avoid light, because they be glare easy ageing, shorten service life, reduce the sensitivity and in severe cases even can damage the components.

(2) Test instruments used and stored in the process should be to prevent contamination. If acid-base environment will affect millions of acidity measurement results; Do many samples measure, sample containers after each use all should immediately rinse off. In addition, stray magnetic field on the influence of the electric current is also a generalized pollution.

(3) If the instrument have calibration battery, best inspected once every six months, such as voltage is not required to replace, otherwise, it will affect the measurement accuracy.

(4) All kinds of measuring film electrode used to often flush, and regular cleaning, long-term when not in use, should take immerse save electrode, to prevent electrode weather-shack, performance becomes poor.

(5) A headscarf inspection flow meter in the instrument as testing the use of indicators more, but it very afraid of hard-hit, so every time with finish after, especially in the instrument move process, should make its a short circuit state.

(6) The instrument mechanical transmission device of friction surface mission activities between regular cleaning, add the lubricating oil, to delay or reduce wear resistance.

(7) Testing instruments are generally quantitative testing instrument, the accuracy of the assured shall, in accordance with relevant provisions, therefore need regular check, calibration. Also, in the instrument after after repair, also should be set before was qualified to use again.

      In addition, medical equipment maintenance, there are many other special content, such as organic glass element, should avoid to touch the organic solvents; Gas chromatography when use need to avoid flammable gas, and the hydrogen source must be away from fire, etc. Usually these content in the instrument using the specifications have detailed hand over to treat, shall be responsible for the maintenance work of the staff should read carefully the instructions to the relevant content, for the correct maintenance.


      The second quarter medical test instruments maintenance should have the conditions.

How should inspection medical devices maintenance?(1)

     Any medical equipment, no matter how advanced the design, perfect, in use process all can't avoid for various reasons, have this or that kind of fault, just different brand, different manufacturer medical equipment failure rate different ways. To guarantee the normal work of the instrument, to the instrument for regular maintenance and repair in time is very important. Below Perlong Medical  nets , for medical test instruments characteristics and maintenance requirements, instrument maintenance should have the condition, instrument malfunction, types and reasons, the rule of the instrument maintenance program and the commonly used method, the medical test instruments used electronic parts inspection content to do some simple introduction.

      The first chapter medical test the characteristics of the medical devices and maintenance requirements:

1. The characteristics of the medical test instruments
Medical test instrument is used for disease diagnosis, disease research and drug analysis of the modernization of the laboratory instruments, its main characteristics are as follows:
1). The structure is very complicated
Medical test instruments is more with light, machine, electricity in one of the instrument, use the devices of various kinds. Especially as instruments of automation degree of the instrument and improve miniaturization, instrument function unceasingly strengthens, various automatic detection, automatic control functions of increased more compact structure, instrument more complex.
2). Medical test medical equipment involving technology field widely
Medical test instruments often involving optical, mechanical, electronic, computer, materials, sensors, biochemistry, radiation technology field, is multidisciplinary technical mutual infiltration and union product.
3). Medical test medical equipment technology are very advanced
Medical test instruments always follow the relevant subject's front. The development of electronic technology, computer application, new material and new devices and the application of the new analysis method and so on are in medical test instruments reflected.
4). Medical test medical instrument accuracy is very high
Medical test instruments specifically used to measure the some the existence of matter, composition, structure and characteristics, and give the qualitative or quantitative analysis result, so accuracy requirement is very high. Medical test instruments is precision instruments.
5). Demand is high for the environment
Due to medical test instruments has above characteristic, as well as some of the key parts of the special properties, decided to instrument for environmental conditions demanding.

2. Medical test instruments maintenance
      Instrument maintenance the purpose of the work is to reduce or avoid contingency of failure, delay the inevitability of failure, and make sure that the performance stability and reliability. Instrument maintenance work throughout the entire process is a long-term work, and therefore must be the instrument according to the characteristics, structure and use process, and in the light of easy to malfunction link, make specific maintenance measures, by the specialist is responsible for the implementation.
1) General maintenance work
General maintenance work include the are those which have a common, almost all the instruments are need to pay attention to the question, basically have the following:
(1) the instrument grounding: grounding problem in addition to instrument performance, reliability has the influence, but also about the users of the personal safety is of vital importance, so all the utility grid access device must be meet reliable landlines.

(2) the power supply voltage: because the utility voltage fluctuation is bigger, often beyond the scope of the requirements, in order to ensure the stability of power supply is to be baled, an interfluent stable power supply. Demanding instrument with separate best voltage stabilizer. In addition, note that the plug wire connection should be good, when using, never put jack position to make wrong, causing damage to the instrument.

(3) instruments work environment: environment on precision testing instrument performance, reliability, measurement results and life has a great influence, therefore it has the following several aspects of the requirements:
One: Dust: all kinds of optical devices and instruments some switch, contacts and so on, often should keep clean. But because of the high precision optical components, so the method, clean liquid and other clean all have special requirements, in doing the cleaning carefully before reading the instruments maintenance instructions, should not be hasty, in order to avoid bruising, damage the optical surface.

Two: The moistureproof: the optical components, photoelectric instrument components, electronic components after damp, easy to mildew, damage, therefore, it is necessary to check regularly, often change in time desiccant; Long-term need not when should be regularly boot electricity to keep off the moisture to moistureproof purpose.

Three: To prevent heat: inspection instrument generally require and storage environment appropriate, fluctuation of smaller temperature, so general configuration temperature regulator (air conditioning), usually temperature to keep in 20-25 ℃ the most appropriate; In addition also requires far away from heat and avoid direct sunlight.

Four: The shock: will not only affect the vibration test instrument performance and measurements, still can cause certain precision components damage, therefore, request the instrument and laid the table or away from the source of cement on the vibration reduction.
Five: And corrosion prevention: in the use of the instrument in the process and stored, should avoid to contact a soda acid corrosive gas and liquid environment, in order to avoid the various components erosion and damage.

The above is the instrument of the main content of the general maintenance, plus external all instruments in shutdown stop when, want to shut off the switchboard power source, and power plug pulled out, to ensure safety.

Machines Used in Operating Room & Their Uses

   Today, operating rooms in major hospitals throughout the industrialized world are equipped with a wide range of specialized machinery designed to achieve a single set of goals: assisting the surgical team to execute the operation as quickly and efficiently as possible. Medical technology also plays a crucial role in patient safety by monitoring vital signs (body temperature, blood pressure and respiration), warning of any impending complications, and helping to head them off before they become life-threatening. According to the Encyclopedia of Surgery, machines used in operating rooms can be grouped into 4 main categories.


      Emergency and Life Support Equipment
      When the heart has to be stopped during surgery or arrests unexpectedly on the operating table, the patient becomes unable to breathe without help so a heart-lung bypass machine, also known as a cardiopulmonary bypass pump, is used to remove carbon dioxide from the blood and replace it with the oxygen needed to sustain life. An intra-aortic balloon pump helps reduce strain on the heart by boosting blood flow to coronary arteries while the patient's vital signs are continuously monitored and displayed on the machine's console. A ventilator (or respirator) is also kept nearby to control or stabilize breathing. Infusions of saline, anesthesia, blood and drugs are delivered by a programmable pump, the bags of fluids suspended from an intravenous pole beside the operating table. In case vital signs stray into the danger zone, a portable cart, called a crash, resuscitation or code cart, stocked with emergency resuscitation equipment, is always close at hand.


      Monitoring Equipment
      Interconnected monitoring machines, all connected to the patient with electrodes and sensors, include an electrocardiogram (ECG) to monitor the heart's electrical activity, a pulse oximeter taped to a finger or toe to keep track of levels of blood oxygen, and an intracranial pressure monitor to gauge the pressure of fluids on the brain.


      Diagnostic Equipment
      During surgery, especially of the chest cavity, additional X-rays may reveal more than earlier radiography was able to capture. In case this becomes necessary, a mobile X-ray unit powered by a battery-operated generator is kept close to the bedside.


      New Surgical Technologies  
      The ideal of all surgery is to get the required job done with minimal trauma to the patient's body and, to that end, new ways of reducing unnecessary risk are constantly being devised and perfected. During some operations, especially very complicated ones, a surgeon may now sit at a console a few feet away from the operating table and guide robotic arms holding tiny cameras or instruments while studying magnified 3-D images of the process as they are projected on a screen. "Scalpels of light," laser beams, may be used to burn, cut or destroy diseased tissue, seal off blood vessels or remove tumors. The laparascope is a fiber-optic instrument similar to a telescope but only about as big around as a fountain pen; increasingly, laparoscopic surgery, also known as minimally invasive surgery (MIS), is replacing techniques that used to require big incisions.

Mobile X-ray Machine

     Mobile X-ray Machine is also called portable x-ray machine, it is widely used in hospitals and clinics to take radiography of patients. 

      Perlong Medical, Nanjing Perlove Medical Equipment Co., Ltd is a professional manufacturer since 1993. There are five models of mobile x-ray equipment in this company, that is PLX102, PLX100, PLX101A, PLX101C, and PLX101D. PLX102 is normal frequency with power supply 3 kw.

How to do a urine test ?

    If you need do a urine test by the urine chemistry analyzer in hospital, then you should do the following by the oder of doctors. 


      Thoroughly wash and rinse the area between the lips of the vagina or the head of the penis. Open the urine collection bag (the plastic bag with an adhesive paper on one end), and place it on your infant. For males, the entire penis can be placed in the bag and the adhesive attached to the skin. For females, the bag is placed over the lips of the vagina.


      Place a diaper over the infant (bag and all). The infant should be checked frequently and the bag changed after the infant has urinated into the bag. For active infants, this procedure may take a couple of attempts. Lively infants can displace the bag, causing an inability to obtain the specimen. Drain the urine into the container for transport to the laboratory. As with adults, the container must be kept refrigerated.


      Deliver it to the laboratory or your health care provider as soon as possible upon completion.
