nasal cannulaleakPerformance testerLike a rigorous medical guardian, dedicated to safeguarding the sealing performance of nasal oxygen tubes. This precision instrument strictly followsYY/T 1543-2017Standard, conduct full angle analysis of oxygen delivery channels'physical examination'Its core testing projectsWhat are they all?beloweditorIntroduce from multiple dimensions

‌Leakage test (airtightness)

In50kPaMaintain under pressure30Within seconds, there must be no continuous bubble generation or pressure drop exceeding the limit to ensure the sealing of the oxygen delivery path. ‌

Pressure resistance test

exert300 kPaContinuous pressure15Second, the catheter must not rupture or undergo irreversible deformation to verify structural integrity. ‌

Airflow resistance test

In5L/minUnder the flow rate, the pressure difference should be ≤3.0kPa；10L/minThe pressure difference under the flow rate should be ≤6.0kPaEnsure the efficiency of oxygen delivery. ‌

‌Anti collapse test

Simulate squeezing scenarios, and the flow rate reduction rate needs to be controlled within the standard range (usually≤25%）To prevent ventilation interruption caused by bending during use. ‌

Therefore,Nasal Oxygen Tube Performance TesterMainly used to test key performance indicators such as airtightness, pressure resistance, airflow resistance, and anti collapse of nasal oxygen tubes, which must comply withYY/T1543-2017National standard requirements for nasal oxygen tubes
