Improved design and application of central oxygen supply system in treatment group of field medical unit / 医疗卫生装备

ABSTRACT

Objection To improve the central oxygen supply system at field conditions to realize rapid transport of oxygen cylinders and enhanced application of medical oxygen.Methods The modified central oxygen supply system was composed of the 40-L oxygen cylinder,triple ball valve,flowmeter,dichotomantheshos hose,disposable nasal catheter for oxygen inhalation,pressure relief valve,immovable hanger and L-shaped trolley for oxygen cylinder.The trolley was composed of a bearing frame designed according to the size of oxygen cylinder,a fixing band and two wheels,which could be used for efficient fixation and rapid transport of oxygen cylinder.Results The improved system met the requirements for materials storage,loading,deployment and withdrawal during oxygen supply,and saved manpower and space.Conclusion The improved system enhances the efficiency of medical oxygen application and the supportability of field medical unit,and thus is worthy promoting in mobile medical unit.
