RESUMO
Objective To develop a portable hanging perfusion support used in the medical tent of field medical unit.Methods The support was composed of a support body,a hanging hook at one end of the body,hanging components and an automatic locking mechanism.The hanging components included two screw hangers and two inverted cone-shaped sleeves.The support body consisted of three stainless steel tubes with different sizes,whose height could be regulated through connecting thread to adapt the support to hanging the dropping bottle.Results The support gained advantages over the traditional one in convenience as well as deployment and withdrawal time,and enhanced medical training efficacy and casualty treatment timeliness greatly.Conclusion The support behaves well in structure,operation and portability,and can be used for patient treatment in battlefield,disaster relief and etc.
RESUMO
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.
