Catheter Residual Vacuum Tester
The Catheter Residual Vacuum Tester is a professional device used to detect the residual vacuum in respiratory suction catheters, aiming to ensure the safety of the catheters during clinical use and prevent patient injury caused by residual vacuum.
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.
Standards
YY/T 0339 - 2019: Suction Catheters for the Respiratory Tract
Features
1. High-precision measurement: It can quickly and accurately detect the location and size of leaks in the pipeline system, enabling precise measurement of minute pressure changes and flow differences.
2. Safe and reliable: It prevents safety accidents and quality problems caused by leaks, ensuring the safety and stability of the production process.
3. Easy to operate: The operation interface is simple and clear, allowing users to complete the testing process by following the prompts. Some testers also feature user-level access control and a comprehensive password protection scheme to ensure data integrity, standardization, and traceability.
4. Multifunctional: Some advanced testers offer features such as real-time data display, data recording and analysis, test report generation, and multiple testing modes, meeting the needs of different users.
Technical Parameters
| Parameter | Specification |
|---|---|
| Measurement Range (Flowmeter) | Usually can measure 30L/min or more |
| Accuracy (Flowmeter) | ±5% or higher |
| Airflow Resistance at a Specific Flow Rate (e.g., 30L/min) | Should be less than 0.1kPa |
Accessoriess
Main unit
Miniature printer
Touchscreen LCD display
Vacuum pump
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).
