Catheter Flow Meter
Applications
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.

Test Procedures
1. Before testing, appropriate test conditions, such as water flow rate and pressure, should be set according to the pipe specifications and testing requirements. This helps to ensure the accuracy and reliability of the measurement results.
2. When connecting the pipes, ensure a tight, leak-free connection. Any leaks will affect the accuracy of the measurement results.
3. During the testing process, keep the testing instrument and pipes clean to avoid contamination affecting the test results. Regularly clean and maintain the instrument to ensure its proper functioning and extend its service life.
4. After the test is completed, turn off the testing instrument, disconnect the pipes, and clean and dry them for future use. This helps prevent corrosion and damage to the instrument and pipes due to prolonged disuse.
