Present status of oxygen supply devices for high altitude parachuting at home and abroad / 医疗卫生装备

ABSTRACT

The necessity of paratroopers equipped with high altitude parachuting oxygen supply devices was elaborated firstly,the selection of oxygen source,working principle and the physiological requirements of high altitude parachuting oxygen supply device were also expounded in detail.The technical indexes of high altitude parachuting oxygen supply devices produced by COBHAM and Airborne systems were mainly introduced.The present status of high altitude parachuting oxygen supply devices in China was summarized.The advantages of high altitude parachuting oxygen supply devices at abroad were analyzed,the gaps between domestic and foreign high altitude parachuting oxygen supply devices and the future development direction of them in China were proposed.In order to provide life support for paratroopers to perform special tasks such as parachuting,the following points need to be specifiedmore scientific researches need to be strengthened in China and the superior performance of high altitude parachuting oxygen supply devices than foreign ones should be developed as soon as possible.
