YY 0285.1 - 2017 Disposable Sterile Intravascular Catheters

Main Uses

The catheter flow tester is mainly used to measure and evaluate the flow performance of medical catheters, such as intravascular catheters, non - intravascular catheters, and infusion set catheters. In the medical field, this tester has a wide range of applications, including but not limited to the following aspects: Product R & D: During the design and R & D stage of catheter products, the tester can help engineers accurately assess the flow performance of different design schemes, providing powerful data support for product iteration. Quality Control: Through batch testing, the tester can ensure that each batch of catheters meets the established flow standards and performance requirements, thus improving the overall quality of products. Clinical Application: The tester can be used to monitor the flow changes of catheters in patients, providing real - time physiological parameter feedback to doctors, which is helpful for adjusting treatment plans, assessing the progress of the disease, and preventing complications.

Technical Parameters

Testing Range: Usually within a certain weight or volume range, such as 1.00 - 600.00g (varying according to catheter specifications) or a specific flow range. Accuracy: The testing accuracy is usually high, such as ±0.01%F.S. (one - ten - thousandth of the full scale) or higher accuracy requirements. Static Water Level Height: Such as 200±5mm and 1000±5mm, etc., to meet different testing needs. The water pump has an automatic circulation function, and the static water level is adjustable. Time Controller: Usually 0 - 60min, with an error not exceeding ±1S, used to control the testing time. Fixtures: Can adapt to catheters of various specifications and types, ensuring the versatility and flexibility of the test. Flow Calculation: Generally, the weighing method is used to calculate the flow (imported flowmeters can also be selected), to ensure the accuracy of the results. Flow Rate: Such as 525ml/min (arbitrary selection) ±25ml/min, etc., to adapt to different testing scenarios. Intelligent Temperature Control: The tester is usually equipped with a micro - computer intelligent temperature - control system to ensure the constancy and accuracy of the test temperature. Special Accessories: Including stainless - steel thermostatic water baths, special connectors, etc., to meet the testing needs of catheters of different specifications and types.
