Technical Field
[0001] This utility model relates to the field of medical packaging bag sealing performance testing technology, specifically a medical packaging bag sealing performance testing device. Background Technology
[0002] Medical packaging bags consist of one side of paper and one side of plastic composite film. They are used to package medical devices that are to be sterilized and are considered the initial inner packaging of the product. The paper side of the packaging bag usually needs to be printed with information about the manufacturer of the medical device or the product.
[0003] Existing medical packaging bag sealing testing devices involve injecting water into the testing cylinder and then using an internal air pump to evacuate the cylinder, creating a vacuum. This allows for observation of whether the medical packaging bags inside bubble in the water. However, when multiple medical packaging bags are placed in the testing cylinder for simultaneous testing, they stack together due to the water. If bubbling occurs in some bags, it becomes difficult to pinpoint which bag has a sealing problem, making the testing process inconvenient. Furthermore, the large internal space of the testing cylinder results in a slow vacuum extraction speed, consequently slowing the testing response and affecting the device's efficiency in detecting the sealing of medical packaging bags.

[0025] Please see Figure 1-4 This utility model provides a technical solution for a medical packaging bag sealing test device: a medical packaging bag sealing test device includes a test device body 1 and a sealing cover 3.

An auxiliary structure 5 is provided on the inner and outer sides of the test cylinder 2 and the sealing cover 3. The auxiliary structure 5 is used to improve the testing efficiency of the device for the sealing of medical packaging bags.
[0026] The auxiliary structure 5 includes a cross-shaped partition 501, a cover assembly, and a snap-fit assembly;
[0027] The cross-shaped partition 501 is fixedly connected to the inside of the detection cylinder 2, and the cross-shaped partition 501 is used to divide the internal space of the detection cylinder 2;
[0028] The cover assembly is used to seal the independent space inside the detection cylinder 2;
[0029] The snap-fit assembly is used to lock and limit the position of the cover plate assembly.
[0030] Please refer to this carefully. Figure 3 The buckle assembly includes a connecting rod 502, a spring 503, a locking block 507, and a locking groove 508;
[0031] The connecting rod 502 is slidably connected to the sealing cover 3. The spring 503 is sleeved on the outside of the connecting rod 502, and the two ends of the spring 503 are fixedly connected to the sealing cover 3 and the protrusion of the connecting rod 502 respectively. The locking block 507 is fixedly connected to one side of the protrusion of the connecting rod 502, and the locking groove 508 is opened on the surface of the sealing cover 3.
[0032] In this embodiment: the protrusion of a connecting rod 502 in a downward moving state drives a locking block 507 to insert into a slot 508, so that the locking block 507 and the slot 508 in the locked state lock and limit the movement of the connecting rod 502, thereby locking and limiting the position of a cover plate 504 in a descending state.
[0033] Please refer to this carefully. Figure 3 The slot 508 is used for inserting the block 507 into it, and the block 507 and the slot 508 in the engaged state are used to lock and limit the movement of the connecting rod 502.
[0034] In this embodiment: a locking block 507 and a locking groove 508 in the locked state lock and limit the movement of a connecting rod 502, thereby locking and limiting the position of a lowered cover plate 504.
[0035] Please refer to this carefully. Figure 4 The cover plate assembly includes a cover plate 504, a seal 505, a bellows 506, and a through hole 509;
[0036] The cover plate 504 is fixedly connected to the bottom of the connecting rod 502, the seal 505 is disposed on the outside of the cover plate 504, the bellows 506 is disposed on the bottom of the sealing cover 3, and the through hole 509 is opened on the surface of the seal 505 and extends into the inner cavity of the sealing cover 3.
[0037] In this embodiment: two medical packaging bags are placed in two areas inside the detection cylinder 2, which is divided by the cross-shaped partition 501. Then, the sealing cap 3 is tightly covered at the opening of the detection cylinder 2. The hand presses a connecting rod 502 in sequence, causing the connecting rod 502 to move downward. The connecting rod 502 in the downward state compresses a spring 503, so the spring 503 is compressed. At the same time, the connecting rod 502 in the downward state drives a cover plate 504 to move downward, so that the cover plate 504 in the descending state stretches the bellows 506. The cover plate 504 in the descending state seals one area inside the detection cylinder 2 divided by the cross-shaped partition 501, and one medical packaging bag is stored in a sealed area.
[0038] Please refer to this carefully. Figure 4 The cover plate 504 has a quarter-circular structure, and the connecting rod 502 in the moving state is used to drive the cover plate 504 to move up and down.
[0039] In this embodiment: a connecting rod 502 is moved downwards. When the connecting rod 502 moves downwards, it compresses a spring 503, causing the spring 503 to be compressed. At the same time, the connecting rod 502 moves downwards, causing a cover plate 504 to move downwards.
[0040] Please refer to this carefully. Figure 3 The cover plate 504 in the lowered state is used to stretch the bellows 506, and the cover plate 504 in the raised state is used to compress the bellows 506.
[0041] In this embodiment: when the cover plate 504 in the lowered state stretches the bellows 506, the cover plate 504 in the lowered state seals a region inside the detection cylinder 2 divided by the cross-shaped partition 501, and when the cover plate 504 in the raised state compresses the bellows 506, the cover plate 504 in the raised state releases the seal on a region.
[0042] Please refer to this carefully. Figure 1 A conduit 4 is fixedly connected to one side of the detection device body 1, and the conduit 4 is connected to the mating end of the sealing cover 3.
[0043] In this embodiment: the air pump inside the detection device body 1 is powered on and operated, so that the air pump in operation draws air from the sealing cover 3 and the inside of the detection cylinder 2 through the conduit 4.
[0044] Working principle: When testing the seal of two medical packaging bags, first inject water into the testing cylinder 2, then place the two medical packaging bags in the two areas inside the testing cylinder 2, which are divided by the cross-shaped partition 501. Then, tightly cover the opening of the testing cylinder 2 with the sealing cap 3. Press one of the connecting rods 502 in sequence, causing one of the connecting rods 502 to move downward. The downward-moving connecting rod 502 compresses a spring 503, thus compressing the spring 503. At the same time, the downward-moving connecting rod 502 drives a cover plate 504 to move downward, causing the cover plate 504 to descend. When the bellows 506 is stretched, the cover 504 in the lowered state seals an area inside the detection cylinder 2 divided by the cross-shaped partition 501. A medical packaging bag is stored in an area in the sealed state. The protrusion of a connecting rod 502 in the downward moving state drives a locking block 507 to insert into a slot 508. The locking block 507 and the slot 508 in the locked state lock and limit the movement of the connecting rod 502, thereby locking and limiting the position of the cover 504 in the lowered state. As described above, an area containing another medical packaging bag is sealed.
[0045] At this time, the air pump inside the main body 1 of the detection device is powered on and operated. The air pump, in operation, evacuates the air inside the sealing cover 3 and the detection cylinder 2 through the conduit 4. The air inside the two sealing areas is then extracted through the two through holes 509, and the two sealing areas are in a vacuum state. Then, observe whether the two medical packaging bags in the two sealing areas bubble in the liquid. Since the detection cylinder 2, which is divided by the cross-shaped partition 501, has multiple independent areas inside, the above structure makes it easy to detect the sealing performance of multiple medical packaging bags at the same time. It also avoids the situation where multiple medical packaging bags are stacked together and are inconvenient to observe in the original structure. In addition, the smaller independent space area allows the vacuum gas inside to be extracted faster, thereby increasing the detection response speed and effectively improving the detection efficiency of the device for the sealing performance of medical packaging bags.
