[0032] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0033] Please refer to Figures 1 to 6 As shown, a medical device airtightness testing device includes a water tank 1 and an outer frame 2. Wheels 101 are fixedly installed at the four corners of the bottom of the water tank 1. The outer frame 2 is fixedly connected to the rear side of the water tank 1. Two sets of fixing plates 3 are fixedly connected to the outer side of the outer frame 2. A lifting mechanism 4 is arranged between the two sets of fixing plates 3. An L-shaped lifting plate 5 is fixedly connected to the outer surface of the lifting mechanism 4. Several sets of connecting plates 6 are linearly connected to the front side of the L-shaped lifting plate 5. A locking mechanism 7 is provided on the front side of each connecting plate 6. The lifting mechanism 4 includes a drive motor 401 fixedly installed on the top of the upper fixing plate 3. The two sets of fixing plates 3... A threaded rod 402 is rotatably connected between the two sets of fixed plates 3. The output end of the drive motor 401 extends between the two sets of fixed plates 3 and is fixedly connected to one end of the threaded rod 402. Two sets of fixed rods 403 are also fixedly connected between the two sets of fixed plates 3. A moving block 404 is threadedly connected to the outer circumferential surface of the threaded rod 402. The moving block 404 slides with both sets of fixed rods 403. A through groove 405 is opened on the outer surface of the L-shaped lifting plate 5. A slider 406 is fixedly connected to the outer surface of the moving block 404. The slider 406 extends through the through groove 405 to the front side of the L-shaped lifting plate 5 and is fixedly connected to the L-shaped lifting plate 5.

[0034] In this scheme, the device is first moved to a designated location by the wheel 101 and an appropriate amount of water is injected into the water tank 1. Then, the drive motor 401 is turned on, and the drive motor 401 drives the threaded rod 402 to rotate. The moving block 404 is moved by the guidance of the two sets of fixed rods 403. Then, the L-shaped lifting plate 5 is moved up or down by the slider 406. Thus, several sets of locking mechanisms 7 on the outer surface of the L-shaped lifting plate 5 are moved to a position that is convenient for the user to install the medicine bottle, or the L-shaped lifting plate 5 drives the medicine bottle fixed by the locking mechanism 7 into the water tank 1 for airtightness testing.

[0035] Locking mechanism 7 includes a housing 701, the outer surface of which is fixedly connected to connecting plate 6. An arc-shaped groove 702 is formed on the outer surface of housing 701, and a bending tension spring 703 is fixedly connected within the arc-shaped groove 702. A sliding groove 704 is also formed in the middle of the inner side of housing 701. Several fixing strips 705 are fixedly connected to the inner side of housing 701. Each fixing strip 705 has a sliding groove 706 on its outer surface. A circular ring plate 707 is fixedly connected to the end of each fixing strip 705 away from housing 701. A lever 708 is slidably connected within the arc-shaped groove 702. Furthermore, the lever 708 is fixedly connected to the bending tension spring 703, and a circular plate 709 is fixedly connected to the inner side of the lever 708. The circular plate 709 is slidably connected inside the first slide groove 704. A polygonal slide groove 710 is opened at the top of the circular plate 709, and a through groove 711 is opened in the middle of the circular plate 709. Sliding sliders 712 are slidably connected inside the slide groove 710. A connecting plate 713 is fixedly connected to the upper side of the sliding slider 712. A sliding rod 714 is fixedly connected to the upper side of the connecting plate 713. The sliding rod 714 is slidably connected inside the second slide groove 706.

[0036] In this design, when the medicine bottle enters the outer casing 701 from top to bottom, the lever 708 is first activated. The lever 708 drives the circular plate 709 to slide in the first slide groove 704, thereby driving the second slider 712 to slide in the third slide groove 710. Each second slider 712 then drives the second connecting plate 713 to rotate outward, and the sliding rod 714 on each second connecting plate 713 slides with the second slide groove 706. At this time, the second connecting plate 713 is in an open state, and the medicine bottle can pass through the circular ring plate 707 and the second through groove 711 and abut against the bottom of the L-shaped lifting plate 5. Then, the lever 708 is released, and the lever 708 is subjected to the bending tension spring 703, thereby causing the second connecting plate 713 to close again, thus completing the clamping and fixing of the medicine bottle.

[0037] Sealing mechanisms 8 are provided on the upper side of the locking mechanism 7 and on the outer surface of the L-shaped lifting plate 5. A fixing plate 3 9 is also fixedly connected to the front side of the L-shaped lifting plate 5. An air pump 10 is fixedly installed on the top of the fixing plate 3 9. A connecting plate 3 11 is provided between the locking mechanism 7 and the sealing mechanism 8. One end of the connecting plate 3 11 is connected to the L-shaped lifting plate 5, and a micro-pressure differential sensor 12 is fixedly installed on the other end of the connecting plate 3 11. The sealing mechanism 8 includes a fixing plate 2 801 fixedly connected to the outer surface of the L-shaped lifting plate 5. A pressure differential sensor 12 is fixedly connected to the bottom of the fixing plate 2 801. The telescopic rod 802 and the thrust spring 803 are sleeved on the outer circumference of the telescopic rod 802. The end of the telescopic rod 802 and the thrust spring 803 away from the fixed plate 801 is fixedly connected to the movable plate 804. The outer surface of the L-shaped lifting plate 5 is also provided with a sliding groove 805. The sliding block 806 is slidably connected inside the sliding groove 805. The sliding block 806 is fixedly connected to the movable plate 804. The bottom of the movable plate 804 is fixedly connected to a sealing plate 807. Ventilation grooves 808 are provided in the middle of both the sealing plate 807 and the movable plate 804.

[0038] In this solution, when the medicine bottle is placed inside the locking mechanism 7, the movable plate 804 is first pushed upward. The movable plate 804 drives the slider 3 806 to slide upward along the slide groove 4 805, so that the thrust spring 803 is in a compressed state. Then, the medicine bottle is passed from top to bottom through the differential pressure sensor 12, the annular plate 707 and the through groove 2 711. After the medicine bottle is fixed, the movable plate 804 is released. The movable plate 804 drops due to the thrust of the thrust spring 803, which in turn drives the sealing plate 807 to abut against the opening at the top of the medicine bottle, preventing water from entering the medicine bottle. Then, the lifting mechanism 4 drives the L-shaped lifting plate 5 to descend into the water tank 1. Then, the air pump 10 is turned on. The air pump 10 fills the medicine bottle with appropriate gas through the connecting pipe and the air groove 808. The micro differential pressure sensor 12 can detect the gas discharged from the outer shell of the medicine bottle, thereby completing the detection and alarm of the medicine bottle, meeting the needs of the staff.

[0039] The working principle and usage process of this device are as follows: First, the device is moved to a designated location by the wheel 101 and appropriate water is injected into the water tank 1. Then, the drive motor 401 is turned on, and the drive motor 401 drives the threaded rod 402 to rotate. The moving block 404 is moved by the guidance of the two sets of fixed rods 403. Then, the L-shaped lifting plate 5 is moved up or down by the slider 406. Thus, several sets of locking mechanisms 7 on the outer surface of the L-shaped lifting plate 5 are moved to a position that is convenient for the user to install the medicine bottle, or the medicine bottle fixed by the locking mechanism 7 is moved into the water tank 1 by the L-shaped lifting plate 5 for airtightness testing.

[0040] When the medicine bottle enters the outer casing 701 from top to bottom, the first step is to move the lever 708. The lever 708 drives the circular plate 709 to slide in the first slide groove 704, thereby driving the second slider 712 to slide in the third slide groove 710. Each second slider 712 drives the second connecting plate 713 to rotate outward, and the sliding rod 714 on each second connecting plate 713 slides with the second slide groove 706. At this time, the second connecting plate 713 is in the open state, and the medicine bottle can pass through the circular ring plate 707 and the second through groove 711 and abut against the bottom of the L-shaped lifting plate 5. Then, the lever 708 is released. The lever 708 is subjected to the bending tension spring 703, thereby causing the second connecting plate 713 to close again, thus completing the clamping and fixing of the medicine bottle.

[0041] When the medicine bottle is placed inside the locking mechanism 7, the movable plate 804 is first pushed upwards. The movable plate 804 drives the slider 3 806 to slide upwards along the slide groove 4 805, so that the thrust spring 803 is in a compressed state. Then, the medicine bottle is passed from top to bottom through the differential pressure sensor 12, the annular plate 707 and the through groove 2 711. After the medicine bottle is fixed, the movable plate 804 is released. The movable plate 804 drops due to the thrust of the thrust spring 803, which in turn drives the sealing plate 807 to abut against the opening at the top of the medicine bottle, preventing water from entering the medicine bottle. Then, the lifting mechanism 4 drives the L-shaped lifting plate 5 to descend into the water tank 1. Then, the air pump 10 is turned on. The air pump 10 fills the medicine bottle with appropriate gas through the connecting pipe and the air groove 808. The micro differential pressure sensor 12 can detect the gas discharged from the outer shell of the medicine bottle, thereby completing the detection and alarm of the medicine bottle, meeting the needs of the staff.
