Applications
The catheter residual vacuum tester is mainly used to determine the physical properties of residual vacuum and leakage in suction catheters for the respiratory tract and other similar medical devices. It is one of the important means to evaluate the performance of medical devices such as suction catheters for the respiratory tract, ensuring the safety and effectiveness of these devices during use. By testing the residual vacuum of catheters, the effectiveness of the vacuum control device at the machine end in releasing vacuum can be verified, thus ensuring that respiratory catheters can meet specific performance requirements during use. In addition, this tester can also be used for detecting vacuum leakage in catheter systems of medical devices such as hemodialysis machines, intravenous infusion devices, and ventilators, to promptly identify and resolve leakage issues and avoid medical accidents caused by leakage.

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).
