Discussion On The Setting Up Of Metrological Assurance Program About Scientific Equipments Based On The Measurements Of Medical Laser

Medical measurements, as a kind of metrological assurance program, is used in medical science, which is based on traditional metrological science and compiled with physical or chemical parameters and the tests of relative medical equipments. It includes the administrative framework, technical framework and medical measurement criterion or standard, measurement equipment, administrative regulation, system, specification, and lab certification etc.In order to make the administration of military medical measurements systematize or standardize and improve the effectiveness of military medical metrological assurance, the quality management system and the operating mechanisms should be set up and carried out to achieve the target of military medical measurement assurance.Facing new conditions, the military medical measurement should give service for military affairs, and its aim is metrological assurance of medical equipments used in war time, the measuring instruments for compulsory verification and the other medical equipments. Metrological supervision and management should be strengthened too. In addition, we should deepen the reform of medical measurement, develop the science and technology of medical measurement and improve the effect of comprehensive assurance.In recent years, some achievements have been gained by all relative metrological verifiers with the instruction of leading organizations at all levels. As a result, the security, accuracy and reliability of medical equipments are ensured. With the development of medical measurement, metrological assurance program of medical equipment during all their life time has been put forward. Till now, some clinical first-aid equipments have been controlled during all their lifetime. But some instruments used by the person in basic military medical scientific units aren't still fully controlled now. At the same time, as the biggest military medical science research institute, there are many instruments with numerical superiority, wide range of types and high-grade precision and advancement in AMMS (Academy of Military Medical Science). So if the metrological assurance program is established in our academy, it can be extended to the other military units step by step. Because medical laser is regarded as the measuring instrument for compulsory verification, it is widely used in research work, becoming more and more important in pathology. So it's proposed to set up the metrological assurance program about scientific equipments based on the measurement of medical laser. It's also approved and supported by the Research Centre of Medical Metrology of PLA and the relative organization of our institute.The three-grade metrological guarantee program based on the mode of laser metrological assurance is composed of three kinds of personnel's whole-course monitoring and assuring, such as metrological verifiers, technical engineers and instrument operators.First, the metrological assurance program, based on technical engineers, includes the following items: buying and the basic check before acceptance .First of all, the purchasers should put up the applications about their demands, including the necessities and the specifications, and then with the help of technical engineers, the purchasers should investigate and demonstrate the laser manufacturers about their products. At last the demanded lasers are assured, according to the ratio of the function and price. After that, the engineers should check and verify the lasers; What's more, the regular check and maintenance by the engineers are also needed. If the operators find any unusual condition, the engineers should check and solve the problems of the lasers at once.Second, the metrological assurance program, based on the laser operators, includes the inspection of laser source all the time. For example, they should check the power and cables to make sure their proper conditions and etc. At the same time, they should compile the operating regulations and learn the simple maintenance knowledge in order to prolong the lasers'life-span. The register involving the status of laser, written by operators, is also needed.Third, the metrological assurance program, based on the metrological verifiers, includes the measurement according to the laser's specification. In order to put up suggestions for other purchasers, the verifiers should make commentary for each kind of laser. The verification item includes appearance, stability or repeatability, deviation of indication and so on. In addition, the metrological verifiers should train laser operators to make sure that they can operate the machines correctly. Now the assurance program has already been started. If this system is applied to the scientific works in our institute, it must improve the reliability of scientific data and assure the scientific works to go smoothly.
