Improving oxygen concentrator in medical gas pipeline system based on YY 1468-2016 standard / 医疗卫生装备

Objective To improve the oxygen concentrator in the medical gas pipeline system according to standard YY 1468-2016 Oxygen concentrator air supply system for medical gas pipeline system.Methods Standard YY 1468-2016 about to be implemented was analyzed based on standard YY/T 0298-1998 Medical molecular sieve oxygen generator general technical specification.Management measures were proposed for the oxygen concentrator according to standard YY 1468-2016.Results The oxygen concentrator in the medical gas pipeline system was optimized so that the requirements of compulsory standards were met.Conclusion The oxygen concentrator in the medical gas pipeline system has to be enhanced in running,supervision and management to meet the requirements of the new standard.

One-piece positive-pressure protective suite and its independent source of air supply system in BSL-4 laboratory / 医疗卫生装备

Biological safety is an important international issue. For this reason, WHO published Laboratory Biosafety Manual in 1983, 2003 and 2005. According to the concepts of Biological safety, countries all over the world have developed and established their own national codes of practice for the safe handling of pathogenic microorganism for clinical, studying and epidemiological purposes. In BSL-4 laboratories, individual biosecurity is very important for staffs when they are faced with dangerous level-4 pathogens. In this paper, individual protective equipment and correlative technical requirements for BSL-4 laboratories are introduced.

Pressure-based Monitoring of Medical Central Compressing Air Supply System / 医疗卫生装备

Objective To determine the indexes for evaluating medical central compressing air sypply system.Methods According to the gas equation,pressure calculation was perfomed with the pressure variation as the monitoring subject.Results Such parameters could be used for monitoring medical central compressing air supply system as as average velocity & instanteous velocity of gas consumption,air compressor's average exhaust velocity & exhaust velocity at start-stop point,and pressure-exhaust velocity curve of air compressor.Conclusion The method can be applied to enhancement of quality management & maintenance of the equipment.
