When the first slide plate 14 slides, it will drive the first spring 16 to move together. The first spring 16 will bring the second slide plate 17 closer to the infusion pump. After the second slide plate 17 contacts the infusion pump, the pressure will be transmitted to the first spring 16 due to the pressure effect, driving the first spring 16 to be in a compressed state. Then the first spring 16 will release the elastic potential energy and apply elastic force to the second slide plate 17. The second slide plate 17 will be close to the infusion pump and fix the infusion pump under the elastic force of the first spring 16. At this time, the staff can observe whether there are bubbles coming out of the surface of the infusion pump; after the second slide plate 17 contacts the infusion pump, the infusion pump will be fixed under the elastic force of the first spring 16, so that the device can fix the infusion pump, reduce the shaking of the infusion pump due to the effect of buoyancy during leak detection, and improve the accuracy of the device's observation of the infusion pump during leak detection.

[0031] Reference Figure 1 As shown, a plurality of transverse plates 7 are fixedly connected to the middle of the water storage tank 12; a third slide bar 72 is slidably connected to the middle of the transverse plate 7; a third spring 73 is fixedly connected to the end of the third slide bar 72; the third spring 73 and the transverse plate 7 are both fixedly connected; a scraper 74 is fixedly connected to the middle of the third slide bar 72; the water storage tank 12 is made of transparent material, and when the staff needs to observe the infusion device from multiple angles, the third slide bar 72 can be pulled so that the third slide bar 72 drives the scraper 74 together When the third slide bar 72 moves, the third spring 73 is in a compressed state, and when the scraper 74 moves, it comes into contact with the side wall of the water tank 12 and cleans the side wall of the water tank 12, thereby reducing impurities attached to the side wall of the water tank 12 and improving the cleanliness of the side wall of the water tank 12; pulling the third slide bar 72 can make the scraper 74 clean the side wall of the water tank 12, thereby improving the convenience of the device for cleaning the water tank 12, and enabling the water tank 12 to more clearly reflect the situation during the leakage detection of the infusion set.
[0032] Reference Figure 2 As shown, a sponge 8 is fixedly connected to the end of the scraper 74; the sponge 8 is located between the scraper 74 and the water tank 12; when the scraper 74 moves, it will also drive the sponge 8 to move together, and when the sponge 8 moves, it will also clean the side wall of the water tank 12 to reduce impurities attached to the side wall of the water tank 12. At the same time, because the sponge 8 is a flexible material, the friction of the scraper 74 on the side wall of the water tank 12 is reduced, and the scratches left on the side wall of the water tank 12 are reduced.
[0033] Working principle: Place the blocked infusion set inside the water tank 12, then inflate the infusion set and start the device to drive the electric push rod 13 to start. After the electric push rod 13 is started, the length of the first slide bar 18 will change and the first slide plate 14 will slide along the slide groove 15. When the first slide plate 14 slides, it will drive the first spring 16 to move together. The first spring 16 will bring the second slide plate 17 closer to the infusion set. After the second slide plate 17 comes into contact with the infusion set, the pressure will be transmitted to the first spring 16 due to the pressure effect, driving the first spring 16 to be in a compressed state. Then the first spring 16 will release the elastic potential energy and apply elastic force to the second slide plate 17. The second slide plate 17 will be under the elastic force of the first spring 16. Under the action, the rubber pad 3 is tightly attached to the infusion set and fixed. At this time, the staff can observe whether there are bubbles coming out of the surface of the infusion set; when the second slide plate 17 contacts the infusion set, the second slide bar 2 will also contact the surface part of the infusion set and slide along the second slide plate 17. When the second slide bar 2 slides, the second spring 22 will be in a stretched state, and then the second spring 22 will release elastic potential energy to drive the second slide bar 2 to squeeze the surface of the infusion set; when the second slide bar 2 contacts the infusion set, the rubber pad 3 will also contact the infusion set. Because the rubber pad 3 is a flexible structure, the rubber pad 3 will absorb the impact generated when the second slide bar 2 contacts the infusion set, thereby reducing the impact on the infusion set. At the same time, because the surface friction coefficient of the rubber pad 3 is larger, the friction between the device and the infusion pump will be increased; when the second slide plate 17 contacts the infusion pump, the suction cup 4 will also contact the infusion pump, and the suction cup 4 will adsorb the surface of the infusion pump after being squeezed by the infusion pump; when the second slide plate 17 moves, it will also drive the bristles 5 to move together, and when the bristles 5 move, they will contact and clean the bottom of the water tank 12 and the inside of the chute 15, reducing impurities at the bottom of the water tank 12 and inside the chute 15; when the infusion pump is placed on the bottom of the water tank 12, it will contact the claw hook 6, and then the middle part of the infusion pump will be hooked by the claw hook 6, increasing the contact area between the device and the infusion pump; the water tank 12 is made of transparent material, and when the staff needs When observing the infusion pump from multiple angles, the third sliding bar 72 can be pulled so that the third sliding bar 72 drives the scraper 74 to move together. When the third sliding bar 72 moves, the third spring 73 will be in a compressed state. When the scraper 74 moves, it will come into contact with the side wall of the water tank 12 and clean the side wall of the water tank 12, thereby reducing impurities attached to the side wall of the water tank 12 and improving the cleanliness of the side wall of the water tank 12; when the scraper 74 moves, it will also drive the sponge 8 to move together. When the sponge 8 moves, it will also clean the side wall of the water tank 12, thereby reducing impurities attached to the side wall of the water tank 12. At the same time, because the sponge 8 is made of flexible material, the friction of the scraper 74 on the side wall of the water tank 12 is reduced, thereby reducing scratches left on the side wall of the water tank 12.
