The Catheter Flow Meter is specifically designed for measuring the water flow rate of medical catheters, including non-vascular catheters, intravascular catheters, and single-use sterile catheters. It is also known as a catheter flow meter, catheter flow detector, non-vascular catheter flow device, infusion set flow tester, or medical device flow tester.
Standards
GB/T 15812.1 - 2005 Non - Vascular Intravascular Catheters - Part 1: General Performance Test Methods
YY 0285.1 - 2017 Disposable Sterile Intravascular Catheters
Features
• Independently developed hydrostatic pressure testing device, capable of maintaining a liquid level of 1000 ± 10 mm.
• Flow rate of 525 ml/min, meeting standard flow rate requirements.
• Equipped with a constant temperature water bath to ensure the test water temperature is 23℃.
• Equipped with a timer for timed testing.
• Test fixture designed strictly according to standard requirements, easy to operate and highly efficient.
• Uniquely designed lifting and lowering structure allows for height adjustment, facilitating testing at different water pressures.
• Equipped with a balance station for convenient placement of balances or measuring cylinders.
• Equipped with an adjustable precision water pump for easy flow rate adjustment.
Technical Parameters
| Parameter | Specification |
|---|---|
| Testing Range | Usually within a weight/volume range (e.g., 1.00 - 600.00g, varying by catheter specifications) or a specific flow range |
| Accuracy | High testing accuracy (e.g., ±0.01%FS, one-ten-thousandth of full scale) or higher requirements |
| Static Water Level Height | e.g., 200±5mm, 1000±5mm (meets different testing needs); water pump has automatic circulation function; static water level is adjustable |
| Time Controller | Usually 0 - 60min, with an error ≤ ±1S; used to control testing time |
| Fixtures | Adapt to various catheter specifications/types, ensuring test versatility and flexibility |
| Flow Calculation | Generally uses the weighing method (imported flowmeters optional) to calculate flow, ensuring result accuracy |
| Flow Rate | e.g., 525ml/min (arbitrary selection) ±25ml/min, etc.; adapts to different testing scenarios |
| Intelligent Temperature Control | Equipped with a micro-computer intelligent temperature-control system, ensuring constancy and accuracy of test temperature |
| Special Accessories | Includes stainless-steel thermostatic water baths, special connectors, etc.; meets testing needs of different catheter specifications/types |
Accessoriess
Static pressure head, height adjustment device, constant temperature water bath, PU tubing
