Study on medical technical support system in tent-form field medical system / 医疗卫生装备

ABSTRACT

Objective To develop a medical technical support module and box-type medical technical equipment so as to supply medical oxygen and water for the tent-form field medical system at field conditions.Methods The medical technical support module had its service orientation analyzed to determine its functional requirements and technical indexes, which involved in PSA oxygen generation technology with variable frequency,constant pressure and self-adaptability to altitudes as well as medical water preparation technology by integrated membrane separation. Box-type modules for medical oxygen generation and medial water preparation were trial-produced with the mode of integrated box and instruments as well as high-density polyethylene as the box material.Results The oxygen production was 1.3 Nm3/h,and the oxygen concentration was 92.7%.The flow volume of cleaning water and purified water was 433.7 and 37.2 L/h respectively at 25℃,and the water quality accorded with the relevant water quality indexes of GB 5749—2006 and the national pharmacopoeia(2010 edition). Conclusion This set of medical equipment can meet the design requirements and can effectively guarantee the medical oxygen and medical water needed for medical treatmentin field tent hospital under field conditions.
