野外多功能隔离病床的设计

Design of A Multi-functional Isolation Sickbed for Field Operations

目的设计一款适用于野外救治传染病患者的隔离病床。方法在病床上安装推拉折叠式隔离罩,通过温湿度控制装置和氧浓度控制装置分别监测并控制隔离罩内气体的温湿度和氧浓度,通过废气消毒灭菌装置杀灭废气中的传染病毒,并通过定期采样检测装置检测排出的废气是否合格。结果隔离罩内气体的温湿度和氧浓度均能控制在设定范围,当其超出报警限值时病床会发出报警提示音,以便医护人员及时消除安全隐患。结论该隔离病床方便、实用,能满足临床使用要求。

Objective To design an isolation sickbed for the treatment of infectious patients in the field. Methods The push-pull and collapsible isolation hood was installed on the sickbed. The temperature, humidity and oxygen concentration of gas inside the isolation hood can be monitored and controlled with temperature and humidity control device, and oxygen concentration control device, respectively. The sterilization for exhaust gas inside the isolation hood can be conducted with sterilization device. The qualified case of sterilized exhaust gas can be detected periodically with sampling and detection device. Results The temperature, humidity and oxygen concentration of gas inside the isolation hood can be controlled within the set range. When the values of the above parameters go beyond the alarm limit, the sickbed will alarm to remind medical staff to eliminate the potential safety hazard in time. Conclusion The convenient and practical isolation sickbed can meet the clinical requirements of field operations.
