RESUMEN

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.
