Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a leak-proof connection device for intravenous infusion. Background Technology

[0002] The infusion leak-proof connection device can be fixed on the infusion bag and limit the needle of the infusion tube to prevent the needle from loosening, thus playing a good role in preventing loosening and leakage. In the existing technology, the infusion tube is easy to come out of the connection device and can easily hinder the operation of medical staff, making the convenience and stability of use less than ideal.

[0003] For example, patent publication number CN217245944U specifically describes an anti-dislodgement fixing device applied at the connection between an infusion bag and an infusion set. After the infusion bag and infusion set are connected, the anti-dislodgement fixing device is installed for use. During installation, the ferrule is first slipped onto the infusion tubing of the infusion set near the connecting seat, then lifted upwards and placed on the connecting seat, abutting against the underside of the pressing plate. Next, the first and second arc-shaped arms of the clamp are opened to fit onto the tubing. At this point, due to the presence of two elastic bands between the ferrule and the clamp, the infusion set... During use, the pillow will not fall off the infusion head, providing an anti-dislodgement effect. When changing the infusion bag during infusion, simply pull down to stretch the elastic band, allowing the retainer to be removed from the infusion tube. This allows the needle of the infusion set to be inserted into another infusion bag. Then, remove the anti-dislodgement retainer from the original infusion bag and reinstall it. However, this design presents the problem that the infusion tube can easily detach from the connection device, potentially hindering the operation of medical personnel, resulting in less than ideal convenience and stability in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a leak-proof connection device for intravenous infusion, which solves the problems that the infusion tube is easily detached from the connection device and can easily hinder the operation of medical staff, resulting in less than ideal convenience and stability in use.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a leak-proof connection device for infusion, including a spring clip, a handle provided on the spring clip, an anti-disengagement limiting mechanism installed at the bottom end of the spring clip, and an adjustment mechanism provided on the spring clip;

[0006] The anti-detachment limiting mechanism includes a connecting rod, a rotating seat rotatably connected to the bottom end of the connecting rod, a limiting ring fixedly connected to the bottom end of the rotating seat, an inlet on the limiting ring, a guide groove on the limiting ring, a guide slide block slidably connected inside the guide groove, a lever fixedly connected to the guide slide block, a first spring on one side of the guide slide block, a connecting block inside the guide slide block, a limiting groove on the connecting block, a connecting shaft fixedly connected to the top and bottom ends of the connecting block, a second spring on the connecting shaft, and an anti-detachment baffle fixedly connected to the end of the connecting block.

[0007] Preferably, the top end of the connecting rod is fixedly connected to the spring clip, and the bottom end of the connecting rod is rotatably connected to the rotating seat through a damping shaft, so that the rotating seat can rotate and can be easily fixed at any position using damping.

[0008] Preferably, the guide groove matches the guide slide block, and one end of the guide groove is connected to the outside, so that the guide slide block and the anti-detachment baffle can enter and exit the guide groove.

[0009] Preferably, one end of the first spring is fixedly connected to the inner wall of the guide groove, and the other end of the first spring is fixedly connected to the guide slide, so that the first spring can play a resetting role on the guide slide.

[0010] Preferably, the connecting block is rotatably connected to the guide slide via two connecting shafts, and the second spring is configured as a torsion spring, so that the second spring can reset the connecting block.

[0011] Preferably, the length of the anti-dislodgement baffle is greater than the length of the inlet, and the end of the anti-dislodgement baffle extends into the inner side of the limiting ring, so that the anti-dislodgement baffle can block the inlet and prevent the infusion tube from coming out.

[0012] Preferably, the adjusting mechanism includes two fixing nuts, which are fixedly installed on both sides of the spring clip. Each fixing nut is internally threaded with a wing bolt. An adjusting plate is rotatably connected to the end of the wing bolt. A telescopic rod is fixedly connected between the adjusting plate and the inner wall of the spring clip, which can adapt to infusion containers of different sizes.

[0013] This invention provides a leak-proof connection device for intravenous infusion. Compared with the prior art, it has the following advantages:

[0014] 1. This leak-proof connection device for infusion uses a spring clip to clamp onto the infusion bag. Then, the limiting ring is rotated to the bottom outside of the spring clip to avoid obstructing the operation of medical personnel. The infusion tube is then brought close to the anti-dislodgement baffle. The anti-dislodgement baffle rotates inward under force, and the infusion tube enters the limiting ring. The second spring resets the anti-dislodgement baffle to close the inlet, preventing the infusion tube from coming out of the limiting ring, effectively improving the convenience and stability of use.

[0015] 2. This leak-proof connection device for infusion uses a wing bolt. By rotating the wing bolt, the wing bolt rotates and, under the action of the fixing nut, pushes the adjusting plate to move, adjusting the distance between the two adjusting plates, thus adapting to infusion containers of different sizes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3This utility model provides a technical solution: a leak-proof connection device for infusion, including a spring clip 1, a handle 3 on the spring clip 1, an anti-dislodgement limiting mechanism 2 installed at the bottom of the spring clip 1, and an adjustment mechanism 4 on the spring clip 1. The anti-dislodgement limiting mechanism 2 can limit the infusion tube and prevent the needle on the infusion tube from being stably connected to the infusion bag, thus preventing leakage. At the same time, it will not hinder the operation of medical staff, effectively improving the stability and convenience of use.

[0023] The anti-dislodgement limiting mechanism 2 includes a connecting rod 201, with a rotating seat 202 rotatably connected to the bottom end of the connecting rod 201. The top end of the connecting rod 201 is fixedly connected to the spring clip 1. The bottom end of the connecting rod 201 is rotatably connected to the rotating seat 202 via a damping shaft, allowing the rotating seat 202 to rotate and be easily fixed at any position using damping. A limiting ring 203 is fixedly connected to the bottom end of the rotating seat 202, which can limit the protruding parts on the infusion tube, thereby preventing the infusion tube from dislodging. The needle is separated from the infusion bag to prevent leakage. The limiting ring 203 can rotate to the outside, making it convenient for medical staff to insert the needle into the infusion bag without hindering the operation. The limiting ring 203 has an inlet 204 and a guide groove 205. The guide groove 205 matches the guide slide 206, and one end of the guide groove 205 is open to the outside, allowing the guide slide 206 and the anti-dislodgement baffle 213 to enter and exit the guide groove 205. The guide slide 206 is slidably connected inside the guide groove 205. A lever 207 is fixedly connected to the guide slide 206. A first spring 208 is provided on one side of the guide slide 206. One end of the first spring 208 is fixedly connected to the inner wall of the guide groove 205, and the other end of the first spring 208 is fixedly connected to the guide slide 206, so that the first spring 208 can play a resetting role for the guide slide 206. A connecting block 210 is provided inside the guide slide 206. A limit groove 209 is provided on the connecting block 210. A connecting shaft 211 is fixedly connected to the top and bottom of the connecting block 210. A second spring 212 is provided on the 11. The connecting block 210 is rotatably connected to the guide slide 206 through two connecting shafts 211. The second spring 212 is set as a torsion spring, so that the second spring 212 can reset the connecting block 210. An anti-dislodgement baffle 213 is fixedly connected to the end of the connecting block 210. The length of the anti-dislodgement baffle 213 is greater than the length of the inlet 204, and the end of the anti-dislodgement baffle 213 extends into the inner side of the limiting ring 203, so that the anti-dislodgement baffle 213 can block the inlet 204 and prevent the infusion tube from coming out.

[0024] Please see Figure 1 and Figure 4The adjusting mechanism 4 includes two fixing nuts 401, which are fixedly installed on both sides of the spring clamp 1. Both fixing nuts 401 are threaded with wing bolts 402. The ends of the wing bolts 402 are rotatably connected to adjusting plates 403. A telescopic rod 404 is fixedly connected between the adjusting plate 403 and the inner wall of the spring clamp 1. The telescopic rod 404 can guide the movement of the adjusting plate 403. By rotating the wing bolts 402, the wing bolts 402 rotate and push the adjusting plate 403 to move under the action of the fixing nuts 401, thereby adjusting the distance between the two adjusting plates 403 and thus accommodating infusion containers of different sizes.

[0025] During operation, the spring clip 1 is clamped onto the infusion bag, and then the limiting ring 203 is rotated to the bottom outer side of the spring clip 1 to avoid obstructing the operation of medical personnel. After the medical personnel insert the needle on the infusion tube into the infusion bag, the limiting ring 203 is reset, and then the infusion tube is brought close to the anti-dislodgement baffle 213, causing the anti-dislodgement baffle 213 to rotate inward under force, so that the infusion tube enters the limiting ring 203. The second spring 212 resets the anti-dislodgement baffle 213 to close the inlet 204, preventing the infusion tube from coming out of the limiting ring 203. When it is necessary to remove the infusion tube from the limiting ring 203, push the lever 207. The lever 207 moves and drives the guide slide 206 to move. The guide slide 206 moves and drives the anti-dislodgement baffle 213 to move, so that the anti-dislodgement baffle 213 is retracted into the guide slide 205, opening the inlet 204 to remove the infusion tube, effectively improving the convenience and stability of use.
