Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a fixing and clamping device for testing medical devices and a use method thereof. Background Art

[0002] The fixed clamping device for medical device testing is a specially designed tool used to firmly fix and support test tubes during the medical device testing process. This device is usually used in laboratory environments to ensure that the test tubes remain vertical or at a specific angle during sampling, adding samples, mixing, centrifugation, heating or other testing operations, preventing the test tubes from tilting or tipping over, thereby ensuring the accuracy and safety of the experiment. The fixed clamping test tube device may include components such as clamps, brackets, clamp seats, and adjustment screws. It is suitable for test tubes of different diameters and heights and can adapt to the needs of various experimental operations.

[0003] Although the current fixed clamping device for medical device inspection can stably clamp and fix the test tube, the clamping range of the clamping device is generally fixed and not easy to adjust, and can only be used for test tubes of specified diameters. When the diameter of the test tube is too large or too small, it cannot be adapted to clamp and fix it, resulting in poor overall applicability. At the same time, the clamping structure used to clamp the test tube is generally in a fixed state and there are generally two clamping structures. When the length of the test tube is less than the distance between the two clamping structures, the two clamping structures cannot clamp and fix the test tube. At the same time, when the test tube is long, the clamping structure can only clamp a section of the test tube, resulting in a portion of the test tube being located above the clamping structure, affecting the stability of the test tube clamping and fixing. Therefore, a fixed clamping device for medical device inspection and a method for use are proposed. Summary of the invention
