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).
