product configuration

Standard configuration: electronic control host, test host, printer

The test principle of

Airflow resistance: after adjusting the test pressure and rated flow rate, the change of pressure value (△P=P2-P1) before and after nasal oxygen tube insertion is recorded, which is airflow resistance.

Flattening resistance: On the basis of completing the airflow resistance test, bend the end of the nasal oxygen tube into a U shape, and record the change of flow rate after stabilization (△Q=Q1-Q2).

Patency: not less than 15L/ min oxygen flow can be guaranteed under normal oxygen pressure.

The test application

General functions: nasal oxygen tube airflow resistance, flattening resistance, patency, leakage test, pressure strength
