Development of high altitude stretcher / 医疗卫生装备

ABSTRACT

Objective To develop a new type of stretcher to meet the needs of medical evacuation in high altitude region. Methods The stretcher was composed of a bearing plate, a protective shield, a control unit and external accessories. An enclosed space was formed by the shield and plate,and there were an air inlet and outlet in the shield to regulate the pressure and oxygen content in the space. An electric blanket was put on the plate, which was combined with the control unit to execute dynamic monitoring and control of the temperature and oxygen content in the shield.Results The stretcher enhanced the casualty safety during transport so that the effect of high altitude on casualty conditions could be decreased effectively. Conclusion The stretcher can be used for casualty transport in high-altitude conditions while reduce the casualty riks.
