Design and development of intelligent infusion device under natural disaster condition

目的探讨输液泵在自然灾害条件下医学救援作用和特点,研制一种高性能、便捷性和多功能的智能输注装置,提高其医学救援保障能力。方法该装置集成输液单元、注射单元、加温单元、体征监护单元、网络通讯单元和控制单元设计研制。输液单元采用半挤压式工作原理,与注射泵共同实现“一快两慢”功能,输注液体进行可控加温,体征监护单元实时采集患者生命体征参数。结果经测试,高低温环境下,对比输注流速,温度补偿后输液流速误差小于4%;高压或低压环境下,对输液泵输注速率和准确性无显著影响;湿度对输注准确性无显著影响;电池自持时间大于6 h,满足自然灾害条件下出现的重大伤情救治对患者液体输注和加温、体征监护及管理等需求。结论该智能输注装置具有集成化程度高、操作简单、方便携带,环境适应性强,可实时监测报警及管理等优点,同时还可安装于智能生命救治后送舱成套装备应对多样化自然灾害现场的急救和治疗,有效地提高自然灾害条件下医学救援保障能力。

Objective Based on the analysis of the function and characteristics of infusion pump in medical rescue under natural disaster conditions,an intelligent infusion device with high performance,convenience and multifunction is designed to improve its medical rescue support capacity.Methods This intelligent infusion device integrates the infusion unit,the injection unit,the heating unit,the physical signs monitoring unit,the network communication unit and the control unit.Among them,the infusion unit adopts the working principle of semi-extrusion,and realizes the function of"one fast and two slow"together with the injection pump.The infusion fluid can be controlled heated.The physical signs monitoring unit can collect the vital sign parameters of patients in real time.Results Compared with the infusion velocity in high and low temperature environment,the error after temperature compensation was less than 4%.Under high pressure or low pressure,the effect on infusion rate and accuracy of infusion pump is not obvious.Humidity had no significant effect on infusion accuracy.The battery self-sustaining time was more than 6 hours,which met the needs of liquid infusion and heating,physical signs monitoring and management of patients in the treatment of major injuries under natural disaster conditions.Conclusion The intelligent infusion device has high integration degree,simple operation,convenient port capacity,strong environmental adapt capacity,real-time monitoring alarm system,etc.It can also be installed in the complete equipment of intelligent life treatment and transport cabin to deal with the first aid and treatment of diversified natural disaster sites,which effectively improves the medical rescue support capacity under natural disaster conditions.
