Description

Technical Field

[0001] This utility model relates to the field of medical device testing, and more specifically, to a pressure resistance testing device for medical device containers. Background Technology

[0002] Withstand voltage testing is one of the main methods for verifying the ability of electrical appliances, equipment, devices, circuits, and electrical safety tools to withstand overvoltage. Medical device containers require withstand voltage testing during the production process.

[0003] A search revealed that Chinese patent CN222926543U discloses "a high-efficiency medical device container pressure resistance testing device, particularly relating to a medical device container pressure resistance testing device, including a base, a connecting column fixed to the right side of the inner wall of the base, a lifting assembly inside the connecting column, feeding and conveying the medical device container through a feeding and conveying device, a servo motor a driving two clamping plates to clamp and fix the medical device container, a servo motor c driving the medical device container to rotate at a fixed angle to fit against the upper surface of the negative conductive sheet, a servo motor b driving the positive conductive sheet to move downwards to fit against the medical device container, and pressure resistance testing of the medical device container is performed through the positive and negative conductive sheets, and the servo motor b reversing to drive the positive conductive sheet to detach, thus repeating the pressure resistance testing of the medical device container in a cycle, solving the problem that the existing device requires frequent disassembly and assembly, which is too cumbersome and affects the testing efficiency of the medical device container." However, the following defects still exist: (1) The translational clamping method of the clamping plate in the device is difficult to ensure that containers of different sizes can be accurately clamped in the center position each time. If the container is tilted, the contact state between the container and the conductive sheet is unstable, resulting in poor contact and causing deviation in the test results.

[0004] (2) The positive and negative conductive plates of the device are in a completely exposed state. If the container breaks under extreme conditions, the fragments and impacts may easily injure nearby workers. Therefore, a pressure resistance testing device for medical device containers is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problem that the translational clamping method of the clamping plate in the existing device cannot guarantee that containers of different sizes can be accurately clamped in the center position every time. If the container is tilted, the contact state between the container and the conductive sheet is unstable, resulting in poor contact and deviation in the test results. This invention provides a pressure resistance testing device for medical device containers to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a pressure resistance testing device for medical device containers, including a base, a testing component for testing the pressure resistance of medical device containers is provided on the top of the base, and a protective component is provided on the top of the base to prevent unqualified containers from breaking and injuring workers. The detection assembly includes a sleeve bolted to the top of the base. A conductive element is slidably disposed on one side of the sleeve. Two sets of placement platforms are symmetrically disposed on the top of the base. A rotating element is rotatably connected to the sleeve. A clamping element is fixedly installed on the periphery of the rotating element. The clamping element is located above the placement platform.

[0007] As a preferred technical solution of this utility model, the protective component includes a first servo motor fixedly installed on one side of the base, a first bidirectional lead screw fixedly installed at the output end of the first servo motor, a transparent protective cover slidably connected to the first bidirectional lead screw, and two sets of transparent protective covers arranged symmetrically, with the conductive component located inside the transparent protective cover.

[0008] As a preferred technical solution of this utility model, the conductive component includes a second servo motor fixedly installed on the top of the sleeve, a second bidirectional lead screw is installed at the output end of the second servo motor, and a bent plate is symmetrically slidably connected on the second bidirectional lead screw. A positive conductive plate and a negative conductive plate are fixedly installed at the ends of the bent plate respectively, and the positive conductive plate is located above the negative conductive plate.

[0009] As a preferred technical solution of this utility model, the rotating component includes a third servo motor fixedly installed on the top of the base, a small gear is installed at the output end of the third servo motor, the small gear meshes with a large gear, the large gear is connected to a sleeve bearing, and a disc is fixedly connected to the top of the large gear.

[0010] As a preferred technical solution of this utility model, the clamping member includes a support platform bolted to the side wall of the disc. There are four sets of support platforms. A fourth servo motor is fixedly installed on one side of the support platform. A fourth bidirectional lead screw is installed at the output end of the fourth servo motor. Two sets of sliders are symmetrically slidably connected on the fourth bidirectional lead screw. Silicone pads are fixedly installed on the inner side of both sets of sliders.

[0011] As a preferred technical solution of this utility model, the support platform is located between the positive electrode conductive sheet and the negative electrode conductive sheet, inside the transparent protective cover, and the transparent protective cover has a groove corresponding to the shape of the support platform.

[0012] As a preferred technical solution of this utility model, a protrusion is symmetrically fixedly connected to one side of the slider, and a groove is opened on the side wall of the support platform corresponding to the protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. With the set detection components, when in use, first place the medical device container to be tested on the placement stage. The clamping component will hold the container and position it on the center line, ensuring the stability and accuracy of the container in the subsequent testing process. The rotating component continues to rotate, rotating the clamping component holding the container to the position of the conductive component. The sliding conductive component can be flexibly adjusted according to the position of the container to ensure good conductive contact. Connect the power supply of the detection equipment to the conductive component. The detection equipment applies a certain voltage and current to the container to perform a withstand voltage test on the container. 2. With the protective components in place, when in use, the first servo motor drives the first bidirectional lead screw to rotate, and the distance between the two sets of transparent protective covers will change. As the two sets of transparent protective covers get closer and closer, they will eventually dock with each other to form a relatively closed protective space. Even if the unqualified container breaks, the resulting fragments and impact force will be blocked inside by the transparent protective cover and will not splash to the outside to harm the staff.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] like Figure 1 As shown, this embodiment proposes a pressure resistance testing device for medical device containers, including a base 1, a testing component 2 for testing the pressure resistance of medical device containers is provided on the top of the base 1, and a protective component 3 is provided on the top of the base 1 to prevent unqualified containers from breaking and injuring workers. like Figure 2 As shown, the testing component 2 includes a sleeve 201 bolted to the top of the base 1. A conductive element 202 is slidably disposed on one side of the sleeve 201. Two sets of placement platforms 203 are symmetrically disposed on the top of the base 1. A rotating element 204 is rotatably connected to the sleeve 201. A clamping element 205 is fixedly installed on the periphery of the rotating element 204, and the clamping element 205 is located above the placement platform 203. In use, the medical device container to be tested is first placed on the placement platform 203. The clamping element 205 will clamp the container and position it on the center line, ensuring the stability and accuracy of the container in the subsequent testing process. The rotating element 204 continues to rotate, rotating the clamping element 205 holding the container to the position of the conductive element 202. The slidably disposed conductive element 202 can be flexibly adjusted according to the position of the container to ensure good conductive contact. The power supply of the testing equipment is connected to the conductive element 202, and the testing equipment applies a certain voltage and current to the container to perform a withstand voltage test on the container.

[0021] like Figure 2As shown, the protective component 3 includes a first servo motor 301 fixedly mounted to one side of the base 1. A first bidirectional lead screw 302 is fixedly mounted on the output end of the first servo motor 301. A transparent protective cover 303 is slidably connected to the first bidirectional lead screw 302. There are two sets of transparent protective covers 303, which are symmetrically arranged. The conductive element 202 is located inside the transparent protective cover 303. In use, the first servo motor 301 drives the first bidirectional lead screw 302 to rotate, and the distance between the two sets of transparent protective covers 303 will change. As the two sets of transparent protective covers 303 get closer, they will eventually dock with each other to form a relatively closed protective space. Even if the unqualified container breaks, the resulting fragments and impact force will be blocked inside by the transparent protective cover 303, preventing them from splashing out and injuring the staff.

[0022] like Figure 3 As shown, the conductive component 202 includes a second servo motor 2021 fixedly mounted to the top of the sleeve 201. A second bidirectional lead screw 2022 is mounted on the output end of the second servo motor 2021. A bent plate 2023 is symmetrically slidably connected to the second bidirectional lead screw 2022. A positive conductive plate 2024 and a negative conductive plate 2025 are fixedly mounted on the ends of the bent plate 2023, with the positive conductive plate 2024 located above the negative conductive plate 2025. In use, the second servo motor 2021 drives the second bidirectional lead screw 2022 to rotate, and the bent plate 2023 moves linearly along the axis of the second bidirectional lead screw 2022. The positive conductive plate 2024 and the negative conductive plate 2025 fixedly mounted on the ends of the bent plate 2023 also move closer to the container. After the positive conductive plate 2024 and the negative conductive plate 2025 make good contact with the container, a certain voltage and current are applied to the container to test whether the pressure resistance performance of the container meets the standard requirements.

[0023] like Figure 5 As shown, the rotating component 204 includes a third servo motor 2041 fixedly mounted to the top of the base 1. A pinion 2042 is mounted on the output end of the third servo motor 2041, and the pinion 2042 meshes with a large gear 2043. The large gear 2043 is connected to the bearing of the sleeve 201, and a disc 2044 is fixedly connected to the top of the large gear 2043. In use, the third servo motor 2041 drives the pinion 2042 to rotate, and the pinion 2042 drives the meshing large gear 2043 to rotate. The rotational motion of the large gear 2043 is directly transmitted to the disc 2044, ensuring the smooth rotation of the disc 2044 around the axis of the sleeve 201.

[0024] like Figure 5 and Figure 6As shown, the clamping component 205 includes a support platform 2051 bolted to the side wall of the disk 2044. There are four sets of support platforms 2051. A fourth servo motor 2052 is fixedly mounted on one side of each support platform 2051. A fourth bidirectional lead screw 2053 is mounted on the output end of the fourth servo motor 2052. Two sets of sliders 2054 are symmetrically slidably connected to the fourth bidirectional lead screw 2053. Silicone pads 2055 are fixedly mounted on the inner sides of both sets of sliders 2054. In use, the fourth servo motor 2052 drives the fourth bidirectional lead screw 2053 to rotate, causing the two sets of sliders 2054 to move accordingly. The distance between the two sets of sliders 2054 changes, and the silicone pads 2055 on the inner sides of the two sets of sliders 2054 gradually move closer to the container, thus stably clamping the container onto the disk 2044.

[0025] like Figure 3 As shown, the support platform 2051 is located between the positive conductive sheet 2024 and the negative conductive sheet 2025, inside the transparent protective cover 303. The transparent protective cover 303 has a groove corresponding to the shape of the support platform 2051. Because the support platform 2051 is located between the positive conductive sheet 2024 and the negative conductive sheet 2025, it can accurately position the container, ensuring that the container is in a suitable relative position with the positive conductive sheet 2024 and the negative conductive sheet 2025, thus preparing for subsequent withstand voltage testing. The transparent protective cover 303 can effectively block dangerous factors such as electric arcs and splashes that may occur during the testing process, protecting the safety of the operators.

[0026] As shown in Figure 6, a protrusion is symmetrically fixed to one side of the slider 2054, and a groove 4 is provided on the side wall of the support platform 2051 corresponding to the protrusion. Under the constraint of the groove 4, the slider 2054 can only move along the straight line direction specified by the groove 4, and will not rotate around its own axis or deviate in other directions.

[0027] Specifically, when using this medical device container pressure resistance testing device: (e.g.) Figure 2As shown, the medical device container to be tested is first placed on the placement platform 203. The clamping member 205 clamps the container and positions it on the center line, ensuring the stability and accuracy of the container in the subsequent testing process. The rotating member 204 continues to rotate, rotating the clamping member 205 holding the container to the position of the conductive member 202. The sliding conductive member 202 can be flexibly adjusted according to the position of the container to ensure good conductive contact. The power supply of the testing equipment is connected to the conductive member 202. The testing equipment applies a certain voltage and current to the container to perform a withstand voltage test. The first servo motor 301 drives the first bidirectional lead screw 302 to rotate, and the distance between the two sets of transparent protective covers 303 will change. As the two sets of transparent protective covers 303 get closer and closer, they will eventually dock with each other to form a relatively closed protective space. Even if the unqualified container breaks, the resulting fragments and impact force will be blocked inside by the transparent protective cover 303 and will not splash to the outside to harm the staff.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
