Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a catheter fixing device. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. During hemodialysis, two catheters are inserted into the patient's arms at the same time. One catheter is used to discharge blood containing solutes and toxins, and the other catheter is used to discharge the purified blood into the patient's body.

[0003] During hemodialysis, the catheter needs to be fixed. In the prior art, when the catheter is fixed, the catheter is fixed to the arm with adhesive tape. The adhesive tape has a certain viscosity. When sweat appears on the patient's arm, the bonding strength between the adhesive tape and the arm is reduced, and the adhesive tape is easily separated from the arm, causing the catheter to fall off. Utility Model Content

[0004] The utility model aims to provide a catheter fixing device to solve the shortcomings in the prior art that the bonding strength between the adhesive tape and the arm is reduced, the adhesive tape is easily separated from the arm, and thus the catheter falls off.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A catheter fixing device is designed, including an anti-drop mechanism, wherein:

[0007] The anti-drop mechanism is connected to a plurality of fixing mechanisms for limiting the position of the catheter;

[0008] The anti-slip mechanism comprises a bent plate, the bent plate is connected to the fixing mechanism, a first elastic band is fixedly connected between the two ends of the bent plate, and a plurality of elastic blocks are connected to the first elastic band at equal intervals along the length direction.

[0009] Preferably, the elastic block is a sponge block.

[0010] Preferably, the fixing mechanism comprises two symmetrically arranged clamping plates, the two symmetrically arranged clamping plates are rotatably connected to the upper end of the bent plate, and a locking assembly is connected between the two symmetrically arranged clamping plates.

[0011] Preferably, the splint is an arc-shaped splint.

[0012] Preferably, the locking assembly includes a second elastic band, the second elastic band is fixedly connected to one of the clamping plates, a through hole is provided on the second elastic band, and a hook is connected to the other clamping plate, and the hook can pass through the through hole.

[0013] Preferably, an anti-slip mechanism is connected to the concave surface of the splint, and the anti-slip mechanism comprises an extrusion block, and the extrusion block is fixedly connected to the concave surface of the splint, and one end of the extrusion block is provided with a round surface layer.

[0014] Preferably, a plurality of anti-skid pads are connected to the concave surface of the clamping plate, and the anti-skid pads are located below the extrusion block.

[0015] The utility model provides a catheter fixing device, which has the following beneficial effects:

[0016] The first elastic band contracts a certain distance and contacts the arm, and the bent plate is pulled under the elastic force of the first elastic band, so that the bent plate is in close contact with the arm. At the same time, the first elastic band itself squeezes the arm to be fixed on the arm. The bent plate and the first elastic band move with the arm and will not detach from the arm under the elastic fixation of the first elastic band, thereby preventing the catheter from falling off, thereby improving the catheter fixing effect.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0024] Reference Figure 1-2 , a catheter fixing device, comprising an anti-drop mechanism 1, wherein:

[0025] The anti-drop mechanism 1 is connected to a plurality of fixing mechanisms 2 for limiting the position of the catheter;

[0026] The anti-slip mechanism 1 comprises a bent plate 11, which is connected to the fixing mechanism 2. A first elastic belt 12 is fixedly connected between the two ends of the bent plate 11. A plurality of elastic blocks 13 are connected to the first elastic belt 12 at equal intervals along the length direction. The elastic blocks 13 are sponge blocks.

[0027] Working process: pull the first elastic band 12 downward, the first elastic band 12 is stretched and generates elastic force after being pulled, the distance between the first elastic band 12 and the curved plate 11 increases, the hand wall passes through the space between the first elastic band 12 and the curved plate 11, release the first elastic band 12, the first elastic band 12 contracts under its own elastic force, the distance between the first elastic band 12 and the curved plate 11 decreases, the first elastic band 12 contacts the arm after contracting a certain distance, pull the curved plate 11 under the elastic force of the first elastic band 12, so that the curved plate 11 is in close contact with the arm, and the first elastic band 12 squeezes the arm by itself, thereby fixing it on the arm, the elastic block 13 is located between the first elastic band 12 and the arm to prevent the first elastic band 12 from causing indentations on the arm, place the catheter on the fixing mechanism 2, and the fixing mechanism 2 fixes the catheter. When the arm moves, the curved plate 11 and the first elastic band 12 move with the arm. Under the elastic fixation of the first elastic band 12, they will not detach from the arm, thereby preventing the catheter from falling off, thereby improving the catheter fixing effect.

[0028] Example 2

[0029] When the catheter is fixed by the fixing mechanism 2, the catheter fixing process is complicated and it is not convenient to quickly fix the catheter. Figure 2 As another preferred embodiment of the utility model, the difference from the embodiment 1 is that the fixing mechanism 2 includes two symmetrically arranged clamping plates 21, the two symmetrically arranged clamping plates 21 are rotatably connected to the upper end of the bent plate 11, the clamping plates 21 are arc-shaped clamping plates, and a locking assembly 22 is connected between the two symmetrically arranged clamping plates 21;

[0030] The locking assembly 22 includes a second elastic band 221, which is fixedly connected to one of the clamps 21. A through hole 222 is provided on the second elastic band 221, and a hook 223 is connected to the other clamp 21. The hook 223 can pass through the through hole 222. When fixing the catheter, the two clamps 21 are rotated to increase the distance between the two clamps 21. Then, the catheter is placed between the two clamps 21, and the second elastic band 221 is pulled. The second elastic band 221 is hung on the hook 223 through the through hole 222. The elastic force generated by the pulling of the second elastic band 221 causes the two clamps 21 to rotate toward each other. The two clamps 21 rotating toward each other clamp and fix the catheter. The two clamps 21 are pulled toward each other by the second elastic band 221 to clamp and fix the catheter. The catheter is fixed simply and quickly.

[0031] Example 3

[0032] When the catheter is clamped and fixed by the two clamps 21, relative sliding is likely to occur between the catheter and the clamps 21, thereby reducing the fixing effect of the catheter. Figure 4 As another preferred embodiment of the utility model, on the basis of embodiment 2, an anti-skid mechanism 3 is connected to the concave surface of the splint 21, and the anti-skid mechanism 3 includes an extrusion block 31, which is fixedly connected to the concave surface of the splint 21, and a round surface layer 32 is provided at one end of the extrusion block 31. A plurality of anti-skid pads 33 are connected to the concave surface of the splint 21, and the anti-skid pads 33 are located below the extrusion block 31. When the splint 21 extrudes and fixes the catheter, the extrusion block 31 squeezes the catheter from above. After the catheter is squeezed by the extrusion block 31, the two sides of the catheter squeeze the splint 21, and the anti-skid pads 33 are located between the splint 21 and the catheter, thereby increasing the friction between the catheter and the splint 21, and it is not easy for the catheter and the splint 21 to slide relative to each other, thereby improving the fixing effect of the catheter.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
