野战输血输液加压装置的研制与应用

Design and application of wartime blood transfusion pressurized device

目的:研制一套适应野战时运输伤员过程中使用的快速输血输液加压装置,提高我军野战条件下救治效率和安全性。方法:选择碳纤维材料作为加压板,高强度扭力弹簧提供压力,加压板大小适用于不同规格的血袋和输液袋。输血器与血袋连接处独立配备声光报警器,探测到空气即刻发出声光报警并及时卡住输血管,在加压板的下沿设计断流磁条,输血完毕及时卡住血袋下沿以防止空气输入,确保输注安全。设计完成后的原理样机与现有加压装置进行平行对比测试比较。结果:本研究设计的加压装置可提供5~10 Kpa的施压强度,可以提高输血输液速度3倍以上,输注过程无需电力和人员干预,输注完毕及时报警,克服了现有设备的不足,达到了快速输血输液的目的,加压过程对血液质量基本没有影响。结论:该输血加压装置很好地解决了紧急抢救情况下快速输血输液的问题,操作简单,功能齐全,与现有装置比较各有利弊,本研究设计的加压装置更适用于战时营连级救护所以及伤员在转运过程中使用,值得作为后勤战备急救器材和平时急救物资使用。

Objective:To development a set of rapid transfusion device in order to improve the treatment efficiency and safety under the military field conditions and the transportation of the wounded.Methods:The light and rigid carbon fiber material as the pressure plate and the torsion spring provided pressure high strength.The pressing plate accommodated different sizes of transfusion bags.The sound and light alarm set were connected with the transfusion pipeline immediately audible alarm and clamp the infusion links when detected air through.Results:The pressurizing device was designed to provide a compressive strength of 5-10 Kpa.The transfusion speed improved more than three times after using this apparatus.The power and the process were without human intervention and alarm occurredin time after infusion,so that it made up the disadvantages of existing equipment.The device achieved the purpose of rapid transfusion.There was no effect on the blood quality.Conclusion:The blood pressure device solved the problem of rapid transfusion in case ofemergency treatment.Its pressing process was without human intervention,easy to use,full functioning,especially applied to the battalion aid station even under the field conditions and used of the wounded during transporting.It was more suitable as anemergenceaid equipment for logistics war preparedness and peacetime material.
