Technical Field

[0001] The utility model relates to the technical field of medical device detection, in particular to a deformation detection device for medical devices. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body. During the production process of medical devices, a series of tests need to be carried out on them to ensure that the devices meet the production and use requirements.

[0003] After searching, the existing Chinese patent announcement number is: CN220170220U, which provides a deformation detection device for medical devices. The patent has a fixed plate installed at the end of the stud and a movable plate is movably connected to the surface of the fixed plate through a spring. The spring plays a connecting role between the fixed plate and the movable plate, so that the movable plate still has a certain movable space after the position of the fixed plate is fixed. During the pressure test of the medical device, if the detection part is deformed, the spring will drive the displacement of the movable plate and the limit rod, and the displacement sensor can monitor the displacement data and transmit it to the external data processing equipment, which can quickly determine the critical deformation value of the device.

[0004] Although the above patent can quickly determine the critical deformation value of the instrument, the above-mentioned deformation detection equipment of a medical device still has the following problems: the medical device is not fixed, resulting in detection offset, but most of the fixtures on the market have relatively single functions. When the shapes of the workpieces to be processed are different, the fixture needs to be replaced, which is time-consuming, and the same fixture can only fix workpieces of the same size, which is not convenient for fixing workpieces of different sizes.

[0005] In view of the above problems, a deformation detection device for medical equipment is proposed. Utility Model Content
