Test Procedures

Open-system catheter: Open the catheter vacuum control device to the release position, turn on the vacuum pump, and adjust the flow rate to the specified value (e.g., 30 L/min).

Closed-system catheter: Remove the pressure gauge, turn on the vacuum control device and vacuum pump, adjust the flow rate to the specified value, then switch the vacuum control device to the closed position, and reattach the pressure gauge. Read and record the residual vacuum value measured on the pressure gauge, which is usually expressed in kPa. For respiratory tract suction catheters, the residual vacuum should not exceed the specified value (e.g., 0.33 kPa or 3.4 cmH₂O).
