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.
