The guidewire rupture test device complies with YY04501-2020 Test requirements in Appendix F of Single-Use Sterile Endovascular Catheter Accessories Part 1: Guiding Devices.
The guidewire rupture test is an experimental method used to test the bending resistance of the guidewire and the softness of the tip. Here are the general steps for this test:
1.Prepare the test setup: Select the appropriate guidewire and rupture test device to ensure the accuracy and reliability of the device.
2.Wrap the guidewire: Wrap the guidewire tightly around the cylinder of the test setup, ensuring that the tip end of the guidewire is fixed in the fixture.
3.Unwrap the guidewire: In the process of unfolding the guidewire, observe whether the guidewire is cracked or the surface coating falls off.
4.Check for rupture: Check the rupture of the guidewire and record the location and number of ruptures.
5.Results: Based on the recorded data, the flexural resistance and tip flexibility of the guidewire were analyzed. If the guidewire cracks or the surface coating comes off, further inspection and repair of the guidewire is required to ensure its safety and reliability during use.
In order to ensure the accuracy and reliability of the guidewire rupture test, there are a few things to keep in mind:1Before performing the test, the guidewire needs to be adequately pre-treated, including cleaning, drying, and fixing steps to ensure the stability and reliability of the guidewire during the test. 2.During the test, it is necessary to select the appropriate loading speed and loading amplitude to avoid the destruction of the guidewire by too fast or too large a load. 3.During the test, it is necessary to keep the environment clean and dry to avoid the influence of environmental factors on the test results. 4.At the end of the test, the guidewire needs to be inspected and documented in detail, including the location, number and extent of rupture, for subsequent analysis and evaluation. In conclusion, guidewire rupture testing is an important experimental method that can be used to evaluate the quality and performance of guidewires, providing important support for the quality control of medical devices and products. When conducting the test, it is necessary to pay attention to factors such as pre-treatment before the test, loading speed and amplitude during the test, and the cleanliness and dryness of the environment to ensure the accuracy and reliability of the test.
