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] Example

[0023] Please see Figure 1-4 This utility model provides a technical solution: a Velcro fastening device for an indwelling vein catheter on the back of the hand, comprising:

[0024] The dressing 1 has its bottom end bonded to the outer wall of the indwelling intravenous catheter tubing, and its top end bonded to a positioning device 2. The outer wall of the positioning device 2 is fixedly connected to a limiting device 3, which is adjusted by snap-fit. In use, the bottom end of the dressing 1 can be bonded and fixed to the indwelling catheter tubing. Then, the positioning device 2 and the limiting device 3 fix the position of the indwelling catheter tubing at the patient's wrist and arm, strengthening the fixation of the indwelling catheter in the hand.

[0025] The positioning device 2 includes a collar 20, with an adhesive surface 21 fixedly connected to the inner wall of the collar 20. A tear-off block 22 is attached to the end of the adhesive surface 21 away from the collar 20. The outer wall of the collar 20 is fixedly connected to the limiting device 3. The outer wall of the adhesive surface 21 contacts the patient's wrist. The end of the tear-off block 22 away from the adhesive surface 21 is fixedly connected to the outer wall of the collar 20. The bottom end of the dressing 1 is tightly adhered to the outer wall of the indwelling intravenous catheter tubing. The entire fixing device is then installed onto the indwelling needle. Subsequently, the collar 20 in the positioning device 2 is wrapped around the patient's hand. At the wrist, since the inner wall of the adhesive surface 21 is in contact with the wrist, the adhesive surface 21 of the inner wall of the collar 20 is in contact with the hand. The adhesiveness of the adhesive surface 21 is used to achieve the initial accurate positioning of the indwelling needle tubing in the hand. Then, the tear-off surface is glued to the collar 20. The adhesive surface 21 can be used to fix the indwelling needle tubing. When it needs to be removed later, simply pull the collar 20 with the tear-off block 22 attached to it and tear it off from the outer wall of the adhesive surface 21. The tear-off block 22 makes it easy to remove or adjust the adhesive surface 21 without damaging the patient's skin.

[0026] The limiting device 3 includes a limiting sticker 30, with a sponge ring 31 adhered to the inner wall of the limiting sticker 30. A fixing ring 32 is symmetrically fixed to the side wall of the limiting sticker 30. The inner wall of the sponge ring 31 contacts the patient's hand wall, and the outer wall of the fixing ring 32 is symmetrically fixed to the side wall of the collar 20. After positioning, the limiting device 3 further fixes the device. Since the sponge ring 31 is adhered to the inner wall of the limiting sticker 30, the sponge ring 31 on the inner wall of the limiting sticker 30 fits the patient's hand wall, providing soft cushioning. The fixing ring 32 connects the collar 20 and the connecting rope 33. When the patient's hand length is inconsistent, the medical staff can pull the connecting rope 33 to make the buckle 37 slide along the limiting ring 36 of the locking buckle 35.

[0027] A connecting rope 33 is slidably connected to the outer wall of the fixing ring 32. A fixing buckle 34 is fixedly connected to the outer wall of the connecting rope 33. A locking buckle 35 is fixedly connected to the outer wall of the connecting rope 33. A limit ring 36 is fixedly connected to the inner wall of the locking buckle 35. A buckle 37 is slidably connected to the inner wall of the limit ring 36. The outer wall of the locking buckle 35 is arranged in a linear array along the outer wall of the connecting rope 33. The outer wall of the buckle 37 is slidably connected to the inner wall of the locking buckle 35. Then, the buckle 37 is snapped into the locking buckle 35 in the appropriate position. The fixing buckle 34 can help fix the position of the connecting rope 33. The linear array of locking buckles 35 provides multiple positions to realize flexible adjustment of the tightness of the limit sticker 30, thereby forming a stable fixing structure to prevent the indwelling needle from shifting or falling out.

[0028] When in use, the bottom end of the dressing 1 can be glued and fixed to the indwelling needle tubing. Then, the positioning device 2 and the limiting device 3 are used to fix the position of the indwelling needle tubing at the patient's wrist and arm, strengthening the fixation of the indwelling needle in the hand.

[0029] By tightly adhering the bottom end of the dressing 1 to the outer wall of the indwelling intravenous catheter, the entire fixation device is installed onto the catheter's tubing. Then, the collar 20 in the positioning device 2 is wrapped around the patient's hand. Since the inner wall of the adhesive surface 21 is in contact with the wrist, the adhesive surface 21 of the inner wall of the collar 20 is in contact with the hand. The adhesiveness of the adhesive surface 21 is used to achieve the initial accurate positioning of the catheter tubing on the hand. Then, the tear-off surface is adhered to the collar 20. With the adhesive surface 21 attached, the catheter tubing can be fixed. When it needs to be removed later, simply pull the collar 20 with the tear-off block 22 attached to it from the outer wall of the adhesive surface 21. The tear-off block 22 facilitates the subsequent removal or adjustment of the adhesive surface 21 without damaging the patient's skin.

[0030] After positioning, it is further fixed by limiting device 3. Since the inner wall of the limiting sticker 30 is bonded with a sponge ring 31, the sponge ring 31 of the inner wall of the limiting sticker 30 fits the patient's hand wall and provides soft cushioning. The fixing ring 32 connects the collar 20 and the connecting rope 33. When the patient's hand length is inconsistent, the medical staff pulls the connecting rope 33 to make the buckle 37 slide along the limiting ring 36 of the locking buckle 35.

[0031] Then, the buckle 37 is inserted into the locking buckle 35 in the appropriate position. The fixing buckle 34 can help fix the position of the connecting rope 33. The linear array of locking buckles 35 provides multiple positions to realize flexible adjustment of the tightness of the limiting sticker 30, thereby forming a stable fixing structure to prevent the indwelling needle from shifting or falling out.

[0032] Since the outer wall of the dressing 1 is bonded with a collar 20, the adhesive surface 21 can be torn off and the collar 20 can be torn off the surface of the dressing 1. In subsequent replacement processes, only the dressing 1 needs to be replaced.
