Description

Technical Field

[0001] The utility model relates to the technical field of medical care, in particular to a catheter fixing clamp with adjustable inner diameter. Background Art

[0002] Currently, after putting on a patient's hospital gown, nurses typically secure the catheter using a rubber band, skillfully wrapping the band around the catheter to keep it in place. However, this process requires a considerable amount of time and effort on the part of the nurse, which undoubtedly affects their work efficiency to a certain extent.

[0003] Currently, catheters are mostly fixed using rubber bands that are then clamped to the patient's arm on a hospital gown. Furthermore, the rubber band needs to be wrapped around the catheter several times during operation, making it difficult to quickly secure and clamp catheters of different sizes. This operation also affects the work efficiency of nursing staff. Therefore, a catheter clamp with an adjustable inner diameter is needed.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] The purpose of the utility model is to provide two opposite catheter positioning parts, insert the catheter between the two catheter positioning parts, apply a constant pressure to the catheter surface through the positioning block, and fix the catheter so that the catheter forms an S-shaped fixed structure between the two positioning blocks, thereby preventing the catheter from sliding and achieving a stable limiting effect. At the same time, the clothing is clamped between the positioning protrusion and the positioning long groove, so that the catheter is better fixed to the patient's clothing surface, and the operation is simple.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a catheter fixing clamp with adjustable inner diameter, comprising a clamp and a clamping part, two parallel connecting parts are fixedly provided on one side surface of the two clamps, a hinge shaft is movably connected between the four connecting parts, the outer surface of the hinge shaft is covered with a pressure spring, the ends of the pressure spring are respectively in movably contact with the inner surfaces of the two clamps, the bottom end surfaces of the two clamps are fixed with a catheter positioning part, the inner side surfaces of the two catheter positioning parts are fixed with a positioning mechanism, the bottom end surfaces of the two catheter positioning parts are fixed with an extension part, and the two clamping parts are fixed to the bottom end surface of the extension part.

[0007] Furthermore, the positioning mechanism includes a positioning block and a telescopic assembly, the telescopic assembly is fixedly arranged on the inner side surface of the catheter positioning portion, and the positioning block is fixedly arranged on the outer surface of the telescopic assembly.

[0008] Further, the telescopic component includes a fixed cylinder and a compression spring. The fixed cylinder is fixedly arranged on the inner side surface of the catheter positioning part. A pressure shaft is movably connected to the inner wall of the fixed cylinder. The compression spring is connected between the inner wall of the fixed cylinder and the end surface of the pressure shaft. The positioning block is fixedly arranged on the outer surface of the pressure shaft.

[0009] Further, the two positioning mechanisms are respectively oppositely arranged on the inner side surfaces of the two catheter positioning parts. The cross-section of the positioning block is a semi-annular structure. The arc convex surfaces of the positioning blocks are oppositely arranged, and there is a limiting gap between the two positioning blocks.

[0010] Further, a positioning convex block is fixedly arranged on one side surface of any one of the clamping parts, and a positioning long groove corresponding to the positioning convex block is formed on one side surface of the other clamping part. The outer surface of the positioning convex block is in movable contact with the inner wall of the positioning long groove.

[0011] Further, a first magnetic block is fixedly arranged inside any one of the clamping parts, and a second magnetic block is fixedly arranged inside the other clamping part. The corresponding surfaces of the first magnetic block and the second magnetic block have opposite magnetic properties.

[0012] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] By arranging two opposite catheter positioning parts, after adjusting the flexible catheter to an appropriate length, the catheter is inserted between the two catheter positioning parts. A constant pressing force is applied to the surface of the catheter through the positioning blocks. The two positioning blocks are parallel to each other but not on the same horizontal line. Therefore, there is a limiting gap between the two positioning blocks. After the catheter is fixed, the catheter forms an S-shaped fixed structure between the two positioning blocks, avoiding the sliding of the catheter, and achieving a stable limiting effect. At the same time, by arranging the positioning convex block, the clothing is clamped between the positioning convex block and the positioning long groove, increasing the stress area of the clamping. Since the corresponding surfaces of the first magnetic block and the second magnetic block have opposite magnetic properties, under the action of the magnetic attraction force, the clamping and fixing between the two clamping parts are more stable, and the catheter is better fixed on the clothing surface of the patient, and the operation is simple.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Embodiment:

[0021] As Figures 1-4 shown, an inner diameter adjustable conduit fixing clip includes a chuck 1 and a clamping part 7. On one side surface of the two chucks 1, two juxtaposed connection parts 2 are fixedly provided. Between the four connection parts 2, a hinge shaft 3 is movably connected. A pressure spring 4 is sleeved on the outer surface of the hinge shaft 3. The ends of the pressure spring 4 are respectively in movable contact with the inner side surfaces of the two chucks 1. On the bottom surface of the two chucks 1, conduit positioning parts 5 are fixedly provided. On the inner side surfaces of the two conduit positioning parts 5, positioning mechanisms are fixedly provided. On the bottom surface of the two conduit positioning parts 5, extension parts 6 are fixedly provided. The two clamping parts 7 are fixedly provided on the bottom surface of the extension parts 6.

[0022] The positioning mechanism includes a positioning block 8 and a telescopic component. The telescopic component is fixedly provided on the inner side surface of the conduit positioning part 5. The positioning block 8 is fixedly provided on the outer surface of the telescopic component.

[0023] The telescopic component includes a fixed cylinder 9 and a compression spring 11. The fixed cylinder 9 is fixedly provided on the inner side surface of the conduit positioning part 5. A pressure shaft 10 is movably connected to the inner wall of the fixed cylinder 9. The compression spring 11 is connected between the inner wall of the fixed cylinder 9 and the end surface of the pressure shaft 10. The positioning block 8 is fixedly provided on the outer surface of the pressure shaft 10.

[0024] The two positioning mechanisms are respectively oppositely arranged on the inner side surfaces of the two conduit positioning parts 5. The cross-section of the positioning block 8 is a semi-annular structure. The arc convex surfaces of the positioning blocks 8 are oppositely arranged, and there is a limiting gap between the two positioning blocks 8.

[0025] On one side surface of any clamping part 7, a positioning convex block 12 is fixedly provided. On one side surface of the other clamping part 7, a positioning long groove 13 corresponding to the positioning convex block 12 is provided. The outer surface of the positioning convex block 12 is in movable contact with the inner wall of the positioning long groove 13.

[0026] A first magnetic block 14 is fixedly disposed inside any one clamping portion 7 , and a second magnetic block 15 is fixedly disposed inside the other clamping portion 7 . The corresponding surfaces of the first magnetic block 14 and the second magnetic block 15 have opposite magnetic properties.

[0027] When in use, the two clamps 1 are pinched with the index finger and thumb respectively, and the two clamps 1 are squeezed relative to each other, so that after the pressure spring 4 is compressed, the connecting part 2 rotates relatively along the hinge part, so that the catheter positioning part 5 is relatively separated, and the clamping part 7 is also relatively separated. The catheter positioning part 5 is a semi-cylindrical structure. When the two catheter positioning parts 5 are closed, a cylindrical structure is formed. After the flexible catheter is adjusted to an appropriate length, the catheter is inserted between the two catheter positioning parts 5. At this time, the clamping blocks are separated from the outside of the patient's clothing;

[0028] Further adjust the position of the catheter so that the outer side of the catheter contacts the two positioning blocks 8. At this time, release the chuck 1, the two catheter positioning parts 5 are closed, and there is an extrusion force between the catheter and the positioning blocks 8. According to the size of the catheter, the compression spring 11 is adaptively compressed, and the pressure shaft 10 moves along the fixed cylinder 9, applying a constant pressure to the surface of the catheter through the positioning blocks 8. The two positioning blocks 8 are parallel to each other but not on the same horizontal line. Therefore, there is a limiting gap between the two positioning blocks 8. After the catheter is fixed, the catheter forms an S-shaped fixed structure between the two positioning blocks 8, which prevents the catheter from sliding and plays a stable limiting effect.

[0029] When the clamp 1 is loosened, the clamping part 7 is driven to move relative to the patient's clothes under the resetting action of the pressure spring 4, and the patient's clothes are clamped and fixed. By setting the positioning protrusion 12, the clothes are clamped between the positioning protrusion 12 and the positioning long groove 13, thereby increasing the clamping force area. At the same time, since the corresponding surfaces of the first magnetic block 14 and the second magnetic block 15 have opposite magnetism, the clamping and fixing between the two clamping parts 7 are more stable under the action of magnetic attraction, and the catheter is better fixed to the surface of the patient's clothes. The operation is simple. When disassembly is required, the clamp 1 can be held again to easily remove the catheter fixing clamp and separate it from the patient's clothes.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
