Perlong Medical

    Perlong Medical is multi-function and integrated big group corporation. It own 11 subsidiaries and thousands of employees, even more important ,the group specialized in all different medical products, for example, mobile x-ray machine, stationary x-ray machine, hematology analyzer, diagnostic equipment,clinical lab device,biochemistry analyzer,immunoassay analyzer,etc.In other words,our product line include more styles in medical products.


      Perlong Medical is a growing and more experience group corporation.It was established in 1993,till now,it have 18 years’ developing history.The speed is fast and the result is admired.Why does it last long development?The answer include three sides,one is high quality,All of our products have been awarded the ISO 9000 and ISO 13485 quality management system management certification and TUV quality system certification.This is the lowest standard,for each product is modified according to clients’ suggestion every year ,we are chasing more and more better quality. Some of products are obtained CE certification,at the same time,We are obtaining more CE for producuts, FDA is getting on……I believe our products are popular for home and aboard!


      The second is that price is competitive.You know,we are big manufacturer,if so ,we make more mechanical parts by ourselves,of course,buy some stable and better other parts,then,we can control product costs,the price is reasonable,you don’t worry about it!


      The third side is that we have great research team.We have 15 design rooms for high technology and full of innovation.We obtain several patent technologies to guarantedd our superiority state in medical industry.More and more patent is getting on,this is our focus!Of course,it told us that our senior managing director own good foresight and improve our product competition,that is our strong back!


      More friends,more clients,please join us!We believe we can give you best service and you will get best future!

Why are lobsters being used in new X-ray technologies?

   The latest adv­ance in the war against hidden bombs, lurking cockroaches and illegal immigr­ants comes straight from the floor of the ocean. Lobsters possess one of the most unique vision systems in the animal world, and researchers are working on adapting that system to X-ray scanners that will make steel walls about as opaque as tissue paper.

      X-rays are a form of electromagnetic energy. The spectrum of electromagnetic energy also includes radio waves and visible light. Some materials absorb X-rays, others reflect them and others let them pass through, refracting the beams so that they bend. Refracted X-rays exit the material at a different angle than the one at which they hit.

      A typical X-ray system uses an X-ray generator, which produces a beam of X-rays, and a detection medium (an optic system). To make an image, X-rays are fired at an object. Some of the X-rays pass through the object and are refracted. Other X-ra­ys are absorbed completely, and some are reflected. The detection medium "sees" the X-rays that pass through the object.

      This system works well, but it's not ideal. First, the refracted X-rays are bending at different angles, so it's difficult for the optics to effectively collect and focus them. Second, since the refraction makes the system less efficient, the X-rays have to be pretty high-powered in order for the optics to gather enough energy to form an image. And high-power X-rays aren't the safest thing in the world.

      The eyes of humans and other animals also rely on refraction. But not lobsters. The way a lobster perceives light is different, and it's a visual system that's almost entirely unique to crustaceans. So what makes lobster vision so special? Next, find out why the eye of a lobster is a lesson in visual efficiency.
