Résumé
Objective To design a multi-function first-aid module integrating instruments with the box to solve the existing problems in integration, operation, deployment, withdrawal, environmental adaptability and etc, so as to realize integrated storage, transport and operation of the instruments. Methods The module had its structure, modes of deployment and withdrawal, instruments buffering and vibration isolation, ergonomics and etc designed with the technologies of integrating box and instruments, integration, buffering and vibration isolation, centralized oxygen and power supply as well as the methods of system modeling,structure simulation and CAD.Results The first-aid module was gifted with the functions of respiratory and circulatory rehabilitation,vital signs monitoring,emergency treatment of complex and multi injuries, which could be used as a 2 000 mm×800 mm×600 mm emergency treatment platform when deployed. There were 4 angles for adjusting the backboard to form anti-shock positions for the severe casualties.The module had the time for deployment and withdrawal not more than 5 min,and was easy to deploy,withdraw,transport and store.Conclusion The module behaves well in structure,function,layout,operation and military service when used for the treatment of the severe casualties in the tent-form field medical system,which contributes to enhancing the casualty treatment efficiency and prognosis.[Chinese Medi-cal Equipment Journal,2018,39(5):12-16]
Résumé
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.
