Standards
GB/T 15812.1: Disposable sterile catheters - Part 1: General requirements
Technical Parameters
| Parameter | Specification |
|---|---|
| Test Flow | Usually 30L/min, with an error ≤ ±5%; ensures stable and accurate flow during testing |
| Pressure Range | Generally 0 - 500KPa, with a resolution of 0.01KPa and an error ≤ ±1%; covers the pressure range most catheters withstand in actual use (ensures test comprehensiveness) |
| Measurement System Holding Time | Usually 1 minute (configurable); maintains a stable measurement environment during testing (improves test accuracy) |
| Test Duration | Generally 1 second - 99.9 minutes, with an error ≤ ±1 second; allows flexible setting of test time according to actual needs (ensures test adequacy and effectiveness) |
| Applicable Catheter Types | Applicable to various medical device products: infusion sets, blood transfusion sets, infusion needles, filters, pipelines, catheters, quick-connect fittings, etc. (meets testing needs of different products) |
Accessoriess
Main unit, hydraulic tank, miniature printer
Test Procedures
1. Pre-test preparation
Check the equipment power supply and hydraulic system sealing, and prepare the test tubing and adapter fittings;
2. Sample installation
Connect the tubing to the equipment's hydraulic circuit using a special connector, ensuring a sealed connection;
3. Parameter setting
Select the corresponding standard (e.g., GB/T 15812.1) via the touchscreen, and set parameters such as test flow rate, pressure range, and pressure holding time;
4. Start testing
The equipment automatically fills with fluid and pressurizes, maintaining the set parameters and monitoring for leaks;
5. Process monitoring
Observe pressure changes to confirm whether there are any leakage abnormalities;
6. Completion
After the equipment depressurizes, remove the tubing, record the results, and clean the pipeline.
