[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. Medical devices are divided into electronic devices and surgical instruments. Unlike the diverse manufacturing materials of electronic devices, surgical instruments such as scalpels and forceps are mainly made of metal materials. During the manufacturing process of medical devices, in order to ensure the quality of surgical instruments, they need to be tested for their anti-deformation performance. Medical devices need to be assisted by testing devices when conducting anti-deformation performance testing.
[0003] However, the existing detection devices have low accuracy. During the detection process, it is necessary to observe with the human eye whether the medical device is deformed. The specific deformation can only be observed when the medical device is obviously deformed. If the deformation is not obvious, it is not easy to observe. Therefore, its accuracy is low and it is unable to detect slight deformations of medical devices. The detection of the anti-deformation performance of medical devices is not accurate enough.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example: Reference Figure 1-4 The anti-deformation performance detection device for medical devices shown in the figure includes a box body 1, support blocks 2 are arranged on both sides of the bottom inner wall of the box body 1, and detection components are arranged on the support block 2 and the adjacent outer walls on both sides. A pressure component is arranged in the middle position of the top inner wall of the box body 1, and the pressure component is adapted to the support block 2. The detection component includes an infrared transmitter 3 and an infrared receiver 4 installed at an equal distance on the top of the outer walls on both sides of the adjacent support blocks 2, and the infrared transmitter 3 is adapted to the infrared receiver 4. An alarm 5 is installed at one end of the top outer wall of the box body 1, and the infrared receiver 4 is connected to a PLC controller through a wire, and the PLC controller is connected to the alarm 5 through a wire. A box door 16 is hinged on the outer wall of the box body 1, and the box door 16 is adapted to the box body 1. An observation window 17 is arranged on the outer wall of the box door 16, and the size of the observation window 17 is smaller than that of the box door 16.
[0023] By means of the above structure: when working, the box door 16 is opened, and the medical device to be inspected is placed on the support block 2 for fixing. After the fixing is completed, pressure is applied to the fixed medical device through the pressure component to squeeze the medical device. During this process, the infrared transmitter 3 emits infrared rays, and the infrared receiver 4 receives the infrared rays. As the pressure on the medical device increases, if the medical device is deformed, the middle of the medical device will gradually sink, thereby blocking the infrared rays generated by the infrared transmitter 3. At this time, the infrared receiver 4 cannot receive the infrared rays, and the alarm 5 will sound an alarm, indicating that the medical device is deformed. Compared with traditional detection devices, it can detect slight deformation of medical devices and is more accurate in detecting the anti-deformation performance of medical devices.
[0024] like Figure 2 As shown, the pressure assembly includes a hydraulic cylinder 6 installed in the middle position of the top inner wall of the box body 1, a pressure block 7 is connected to the end of the hydraulic cylinder 6, an induction groove is provided on the bottom outer wall of the pressure block 7, a pressure sensor 8 is installed on the inner wall of the induction groove, a protective pad 10 is provided at the bottom of the pressure block 7, the protective pad 10 is adapted to the pressure block 7, a display 9 is installed in the middle position of the top outer wall of the box body 1, the pressure sensor 8 is connected to the PLC controller through a wire, and the PLC controller is adapted to the display 9 through a wire. During the medical device detection process, the hydraulic cylinder 6 drives the pressure block 7 to descend to squeeze the medical device. Since the force is mutual, the pressure generated by the pressure block 7 on the medical device will react to the pressure sensor 8. The display 9 displays the pressure data received by the pressure sensor 8, and can judge the anti-deformation performance of the medical device based on the real-time observation of the pressure on the medical device. The detection result is expressed in the form of data, which is more convenient to use.
[0025] like Figure 2 As shown, installation grooves are opened on the inner walls of both sides of the box body 1, and electric telescopic rods 11 are installed on the inner walls of the installation grooves. An extrusion plate 12 is installed at the end of the electric telescopic rod 11. The extrusion plate 12 is slidably connected to the top of the support block 2. After the pressure component performs an anti-deformation performance test on the medical device, the electric telescopic rod 11 drives the extrusion plate 12 to squeeze the medical device to further verify the anti-deformation performance of the medical device.
[0026] like Figure 4As shown, threaded rods 13 are installed at both ends of the top outer wall of the box body 1 through threaded rotation, and a fixing plate 14 is installed at the end of the threaded rod 13. The bottom outer wall of the fixing plate 14 and the outer walls on both sides adjacent to the extrusion plate 12 are provided with anti-slip pads 15, and the anti-slip pads 15 are respectively adapted to the extrusion plate 12 and the fixing plate 14. After the medical device is placed on the support block 2, the threaded rod 13 is rotated to drive the fixing plate 14 to descend, and the medical device is squeezed and fixed by the fixing plate 14, so that the medical device remains stable during the detection process and prevents the medical device from moving during the detection process.
[0027] How this utility works:
[0028] During operation, the box door 16 is opened, and the medical device to be tested is placed on the support block 2 for fixing. After the fixing is completed, pressure is applied to the fixed medical device through the pressure component to squeeze the medical device. During this process, the infrared transmitter 3 emits infrared rays, and the infrared receiver 4 receives the infrared rays. As the pressure on the medical device increases, if the medical device is deformed, the middle of the medical device will gradually sink, thereby blocking the infrared rays generated by the infrared transmitter 3. At this time, the infrared receiver 4 cannot receive the infrared rays, and the alarm 5 will sound an alarm, indicating that the medical device is deformed. Compared with the traditional detection device, it can detect slight deformation of the medical device, and the anti-deformation performance detection of the medical device is more accurate;
[0029] During the medical device testing process, the hydraulic cylinder 6 drives the pressure block 7 to descend to squeeze the medical device. Since the force is mutual, the pressure generated by the pressure block 7 on the medical device will react to the pressure sensor 8. The display 9 displays the pressure data received by the pressure sensor 8, and can judge the anti-deformation performance of the medical device based on the real-time observation of the pressure on the medical device. The test results are expressed in the form of data, which is more convenient to use. The electric telescopic rod 11 drives the squeezing plate 12 to squeeze the medical device to further verify the anti-deformation performance of the medical device.
[0030] After the medical device is placed on the support block 2, the threaded rod 13 is rotated to drive the fixing plate 14 to descend, and the fixing plate 14 is used to squeeze and fix the medical device, so that the medical device remains stable during the detection process and prevents the medical device from moving during the detection process.
