Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device tensile testing technology, specifically a medical device tensile testing device. Background Technology
[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, including the necessary computer software. Medical devices include medical equipment and medical consumables.
[0003] Existing medical devices require tensile testing, but the fixing devices used cannot be adjusted according to the medical device. For example, when tensile testing is required for round medical devices, clamping with a splint cannot hold the round medical device well, which may cause the medical device to fall off during the tensile process, resulting in inaccurate test results. Utility Model Content
[0004] The purpose of this invention is to provide a medical device tensile testing device to solve the problem mentioned in the background art where medical devices need to be tested for tensile strength, but the fixing device used cannot be adjusted according to the medical device. For example, when tensile testing is required for a round medical device, if a clamp is used, it cannot hold the round medical device well, which will cause the medical device to fall off during the tensile process, resulting in the problem of test distortion.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a medical device tensile testing device, comprising a testing table and a support plate fixedly installed on the testing table, two reinforcing rods fixedly installed between the support plate and the testing table, a fixing component for fixing a circular medical device is provided on the side wall of the support plate, a clamping component for clamping a strip-shaped medical device is provided on the side wall of the support plate, and a testing component for performing tensile testing on the testing table.
[0006] Preferably, the fixing component includes a hook fixedly installed on the side wall of the support plate, two fixing blocks fixedly installed on the upper end of the support plate, a rotating shaft rotatably installed between the two fixing blocks, a baffle fixedly installed on the axial side wall of the rotating shaft, a first limiting groove and a second limiting groove opened on the hook, an installation groove opened on the baffle, a limiting block slidably installed on the installation groove, a spring provided between the limiting block and the installation groove, and the baffle inserted into the hook.
[0007] Preferably, the clamping assembly includes two first sliding grooves formed on the support plate, a first clamping plate is fixedly installed on the side wall of the support plate, a threaded rod is rotatably installed on the first clamping plate, a second clamping plate is slidably installed on both first sliding grooves, the second clamping plate and the threaded rod are threadedly connected, and friction pads are bonded to both the first clamping plate and the second clamping plate.
[0008] Preferably, the inspection assembly includes two second slide grooves formed on the inspection table, a displacement plate is slidably installed on the two second slide grooves, a fixed plate is fixedly installed on the inspection table, a telescopic cylinder is fixedly installed on the side wall of the fixed plate, and the telescopic end of the telescopic cylinder is fixedly connected to the displacement plate.
[0009] Preferably, the size of the locking block on the baffle is smaller than the size of the first limiting groove.
[0010] Preferably, the fixing components and clamping components on the support plate correspond in position to the fixing components and clamping components on the displacement plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. First, place the round medical device on the hook. Then, rotate the baffle through the rotating shaft. At this time, the baffle enters the first limiting groove, and the limiting block enters the second limiting groove through the action of the spring, thus forming a closed opening. This prevents the round medical device from falling off the hook during the tensile test, which would lead to test failure. After the round medical device is fixed in place, activate the telescopic cylinder. The telescopic end of the telescopic cylinder drives the displacement plate and the fixing component to slide backward along the second slide groove, thereby performing the tensile test on the round medical device.
[0013] 2. When testing a strip-shaped medical device, place the device on the friction pad and rotate the threaded rod. Because the threaded rod is threadedly connected to the second clamping plate, and the second clamping plate is slidably connected to the two first sliding grooves, the two first sliding grooves restrict the rotational displacement of the second clamping plate. At this moment, the threaded rod drives the second clamping plate to move towards the first clamping plate, thus clamping the strip-shaped medical device through the first and second clamping plates. The friction pad increases the friction with the strip-shaped medical device. Then, activating the telescopic cylinder allows for tensile testing of the strip-shaped medical device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1: Please refer to Figure 1 - Figure 5 A medical device tensile testing device includes a testing table 1 and a support plate 11 fixedly installed on the testing table 1. Two reinforcing rods 12 are fixedly installed between the support plate 11 and the testing table 1. The reinforcing rods 12 can increase the stability of the support plate 11. A fixing component 2 for fixing a circular medical device is provided on the side wall of the support plate 11. A clamping component 3 for clamping a strip-shaped medical device is provided on the side wall of the support plate 11. A testing component 4 for performing tensile testing on the medical device is provided on the testing table 1.
[0022] The fixing component 2 includes a hook 21 fixedly installed on the side wall of the support plate 11. Two fixing blocks 22 are fixedly installed on the upper end of the support plate 11. A rotating shaft 23 is rotatably installed between the two fixing blocks 22. A baffle 24 is fixedly installed on the axial side wall of the rotating shaft 23. A first limiting groove 25 and a second limiting groove 26 are provided on the hook 21. An installation groove 27 is provided on the baffle 24. A limiting block 28 is slidably installed on the installation groove 27. A spring 29 is provided between the limiting block 28 and the installation groove 27. The baffle 24 is inserted and installed on the hook 21.
[0023] The inspection component 4 includes two second slide grooves 41 formed on the inspection table 1. A displacement plate 42 is slidably installed on the two second slide grooves 41. A fixed plate 43 is fixedly installed on the inspection table 1. A telescopic cylinder 44 is fixedly installed on the side wall of the fixed plate 43. The telescopic end of the telescopic cylinder 44 is fixedly connected to the displacement plate 42.
[0024] The size of the locking block on the baffle 24 is smaller than the size of the first limiting groove 25. When the baffle 24 rotates, it can smoothly lock onto the hook 21, thereby preventing the round medical device from coming off the hook 21 when it is pulled.
[0025] The fixing components 2 and clamping components 3 on the support plate 11 correspond to the fixing components 2 and clamping components 3 on the displacement plate 42, which can prevent the medical device from being misaligned when stretched, thereby causing the test data to be distorted.
[0026] In this embodiment: First, the circular medical device is placed on the hook 21. Then, the baffle 24 is rotated by the rotating shaft 23. At this time, the baffle 24 enters the first limiting groove 25, and the limiting block 28 enters the second limiting groove 26 by the action of the spring 29, thereby forming a closed opening to prevent the circular medical device from falling off the hook 21 during the tensile test, thus causing the test to fail. After the circular medical device is fixed in place, the telescopic cylinder 44 is activated, so that the telescopic end of the telescopic cylinder 44 drives the displacement plate 42 and the fixing component 2 to slide backward along the second slide groove 41, thereby performing a tensile test on the circular medical device.
[0027] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 and Figure 5 The clamping assembly 3 includes two first sliding grooves 31 formed on the support plate 11. A first clamping plate 32 is fixedly installed on the side wall of the support plate 11. A threaded rod 34 is rotatably installed on the first clamping plate 32. A second clamping plate 33 is slidably installed on both of the first sliding grooves 31. The second clamping plate 33 and the threaded rod 34 are threadedly connected. Friction pads 35 are bonded to both the first clamping plate 32 and the second clamping plate 33. The friction pads 35 can increase the friction with the medical device.
[0028] In this embodiment: When it is necessary to test the strip-shaped medical device, the strip-shaped medical device needs to be placed on the friction pad 35, and then the threaded rod 34 is rotated. Because the threaded rod 34 is threadedly connected to the second clamping plate 33, and because the second clamping plate 33 is slidably connected to the two first sliding grooves 31, the two first sliding grooves 31 can restrict the rotational displacement of the second clamping plate 33. At this time, the threaded rod 34 drives the second clamping plate 33 to move towards the first clamping plate 32, so that the strip-shaped medical device can be clamped by the first clamping plate 32 and the second clamping plate 33. The friction pad 35 is used here to increase the friction with the strip-shaped medical device. Then, the telescopic cylinder 44 is activated to perform a tensile test on the strip-shaped medical device.
