Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and more specifically relates to a mechanism for testing the sealing performance of an injection pump. Background Technology

[0002] An infusion pump is a precision and complex medical infusion device. Its internal tubing contains a variety of functional components and multiple connection points. If there is a leak in the tubing system, it cannot be used to deliver medication normally. Therefore, a leak test is required after the infusion pump is connected to the tubing.

[0003] The current common method is to use water filling for testing. The entire infusion pump is immersed in water, and then air is injected into the pipeline. The bubbling of the pipeline under air is observed. However, this method usually requires manual visual inspection throughout the process, which is visually demanding and inefficient. After testing, the infusion pump also needs to be dried and disinfected to prevent water vapor from seeping into the pipeline and contaminating the medicine during later use. Therefore, the entire testing process is cumbersome, complicated, and inefficient.

[0004] The existing patent with publication number CN114935438A discloses a leak detection device and method for an infusion pump pipeline. It first seals the pipeline of the infusion pump by means of several sealing components, and then tests the pipeline sealing performance by means of an air leak tester, without immersing the infusion pump in water, eliminating the need for visual inspection, reducing labor intensity, and eliminating the need for drying, disinfection and sterilization steps, thus greatly improving the detection efficiency.

[0005] The aforementioned equipment has a fixed testing workbench with grating detection mechanisms on both sides. When workers are installing infusion pump pipeline components, the grating detection mechanisms can prevent sudden equipment operation from causing personal injury. This also means that when testing multiple infusion pump pipelines, the pipeline components (dosing tee, precision filter, and dispensing end) must be installed on all the mounting brackets at once, and then tested together. After testing, they are removed all at once. Obviously, there is still room for improvement in efficiency in this method. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a pump sealing performance testing mechanism that enables simultaneous testing and placement, resulting in continuous placement and testing, and thus higher testing efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pump sealing performance testing mechanism, comprising a workbench and a gas sealing tester located on one side of the workbench, a placement area and a testing area on the workbench, a plurality of slides slidably connected to the workbench, the slides sliding between the placement area and the testing area, a plurality of retainers provided on the slides, a plurality of sealing components provided around the retainers, and the plurality of sealing components being located on the front and rear sides of the slide movement direction and above the retainers respectively, and a driving mechanism provided between the slides and the workbench.

[0008] Furthermore, grating detection mechanisms are provided on both sides of the worktable, and the grating detection mechanisms are close to the detection area of ​​the slide table.

[0009] Furthermore, the driving mechanism includes a drive motor, a lead screw, and a lead screw nut. The drive motor is connected to the lead screw, the lead screw is rotatably connected to the worktable, the lead screw nut is threadedly connected to the lead screw, and the lead screw nut is fixed to the slide.

[0010] Furthermore, a slider is provided on the slide table, and a corresponding slide rail is provided on the worktable. The two ends of the slide rail pass through the placement area and the detection area respectively, and limit blocks are provided at the two ends of the slide rail at the edges of the placement area and the detection area.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During the initial inspection, all slides are moved from the inspection area to the placement area by the drive mechanism, i.e., they slide out. Then, the worker first places the pipeline component of the injection pump on the holder of one of the slides. After placement, the front and rear sides are sealed. Then, the slide immediately moves back to the inspection area and the top is sealed. After sealing, it can be inspected by the gas seal tester. During the inspection, the worker can place another pipeline component of the injection pump on another slide located in the placement area, thus forming continuous placement and continuous inspection, which improves the inspection efficiency.

[0016] Reference Figure 1 The present invention will be further described below.

[0017] A pump sealing performance testing mechanism includes a workbench 1 and a gas sealing tester (not shown in the figure) located on one side of the workbench 1. The workbench 1 is provided with a placement area 2 and a testing area 3. A plurality of slides 4 are slidably connected to the workbench 1. The slides 4 slide between the placement area 2 and the testing area 3. A plurality of retainers 5 are provided on the slides 4. A plurality of sealing components 6 are provided around the retainers 5. The sealing components 6 are respectively located on the front and rear sides of the slides 4 in the direction of movement and above the retainers 5 (not shown in the figure). A driving mechanism is provided between the slides 4 and the workbench 1.

[0018] Specifically, the workbench 1 is equipped with a controller (not shown in the attached diagram), and the workbench 1 is equipped with control buttons 12 corresponding to each slide 4. The control buttons 12 are electrically connected to the controller. After the pipe components are placed on the slide 4, pressing the control button 12 will move the slide 4 back to the detection area 3. This can be done manually. Alternatively, a vision mechanism corresponding to the slide 4 can be installed above the placement area 2 to automatically detect the placement of each pipe component and then automatically drive the slide 4 to move to the detection area 3.

[0019] like Figure 1As shown, during the initial test, all slides 4 are moved from the test area 3 to the placement area 2 by the drive mechanism, i.e., they slide out. Then, the worker first places the pipeline component of the injection pump on the seat 5 of one of the slides 4. After placement, the front and rear sides are sealed. Then, the slide 4 immediately moves back to the test area 3 and the top is sealed. After sealing, it can be tested by the gas seal tester. During the test, the worker can place another pipeline component of the injection pump on another slide 4 located in the placement area 2, thus forming continuous placement and continuous testing, which improves testing efficiency.

[0020] Specifically, the card holder 5 and the sealing component 6 described in this embodiment both adopt the structure disclosed in the patent publication number CN114935438A, entitled "A Leak Detection Device and Leak Detection Method for Infusion Pump Pipeline", to correspond to different infusion pump pipeline components (dosing tee, precision filter, dosing outlet). Specifically, since the pipeline components are all connected by conduits, the movement of the slide 4 will not affect the sealing effect on the pipeline components.

[0021] like Figure 1 As shown in this example, preferably, the workbench 1 is provided with grating detection mechanisms 7 on both sides. The grating detection mechanisms 7 are close to the detection area 3 of the slide table 4 to prevent the worker's hand from reaching into the detection area 3 during detection. Once the grating detection mechanism 7 detects a hand, it will immediately stop the detection to ensure the worker's personal safety.

[0022] like Figure 1 As shown in the preferred embodiment, the driving mechanism includes a drive motor 11, a lead screw 8, and a lead screw nut (not shown in the figure). The drive motor 11 is connected to the lead screw 8, the lead screw 8 is rotatably connected to the worktable 1, the lead screw nut is threadedly connected to the lead screw 8, and the lead screw nut is fixed on the slide table 4. That is, after the drive motor 11 drives the lead screw 8 to rotate, the slide table 4 can be moved through the threaded lead screw nut.

[0023] like Figure 1 As shown in the preferred embodiment, the slide table 4 is provided with a slider (not shown in the attached figure), and the worktable 1 is provided with a slide rail 9 corresponding to the slider. The two ends of the slide rail 9 pass through the placement area 2 and the detection area 3 respectively. Limit blocks 10 or limit sensors are provided at the positions of the two ends of the slide rail 9 at the edges of the placement area 2 and the detection area 3. That is, the slide rail 9 slider ensures the accuracy of the movement of the slide table 4 and improves the accuracy of the sealing. The limit blocks 10 limit the maximum movement position of the slide table 4 in the detection area 3 and the placement area 2.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
