便携式负压校准装置的研制

摘要

Objective: Develop a kind of portable negative pressure calibrator by the design and implement of method. Methods:By the working principle of negative pressure sensor and gas flow sensor, the negative pressure aspirator realizes the calibration function and stability of the monitoring function of the pressure and flow. Results:Stating from the design concept, this portable negative pressure can satisfy the requirement of the quality control and test work. Conclusion:Guarantee the accuracy and efficiency in the clinical first aid and field battle when using attractor. This avoids attractor of iatrogenic injury accident caused by negative pressure fall off.%目的：通过负压校准装置的实现方法和结构设计，研制一种便携式负压校准装置。方法：利用负压传感器和气体流量传感器的工作原理，实现负压吸引器的压力与流量的校准功能及其稳定性的监测功能。结果：从设计理念出发，研制的便携式负压校准装置能满足负压吸引器质量控制检测工作的基本需求。结论：在医院临床急救和野战应急使用时能够保障负压吸引器的准确性和高效性，避免吸引器因负压失准导致的医源性损伤事故。
