Respiratory tube residual vacuum tester

The residual vacuum testing instrument for respiratory catheters is designed and manufactured according to the relevant standards of YY/T0339-2019 "Inhalation catheters for respiratory tract use", and is a specialized testing instrument for detecting respiratory catheters.

Test Principle

Place the vacuum control device in the release position, apply suction at the machine end of the conduit, and test the residual vacuum at the conduit end to verify the effectiveness of the vacuum control device in releasing vacuum at the machine end.

technical features

Printing test data, the instrument consists of an adjustable flow exhalation source (positive pressure gas source), a standard prescribed exhalation pipeline system, etc. It uses special gas path conversion components to ensure easy and fast replacement of the exhalation pipeline system, digital display of inspiratory resistance, zero point correction, accuracy correction, and over range alarm functions, and adopts an electronic flowmeter with high flow control accuracy.

Developed in accordance with Appendix C of YY/T0339-2019 "Inhalation catheters for respiratory use".
