Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a restraint belt used for fixing the upper limbs of patients with arteriovenous fistula puncture. Background Art

[0002] Fixation after arteriovenous fistula puncture is a key step in ensuring the puncture needle is in place and maintaining vascular access. Improper fixation may cause problems such as needle rolling, slipping, and needle tip pain, which not only affects the dialysis effect, but may also cause additional pain and complications to the patient. Movement of the hand position can also cause the needle to slip. Therefore, how to effectively fix the puncture needle has become an important task in hemodialysis care.

[0003] Chinese patent publication number CN204050454U discloses a restraint belt for fixing the upper limbs of patients with arteriovenous fistula puncture, including a restraint belt body, wherein the restraint belt body includes an annular belt that can be sleeved on the thumb and two straight belts connected to the annular belt for fixing to the edge of the bed. Compared with traditional restraints, the restraint belt of the utility model has the following advantages: simple structure, low production cost, and very convenient use. It avoids the danger of the arteriovenous fistula puncture needle falling out during movement of the hand, stays away from the arteriovenous fistula anastomosis area, and completely avoids the pressure on the arteriovenous fistula anastomosis area caused by existing restraints during hemodialysis in patients with upper limb arteriovenous fistula puncture. The blood flow is reduced or even blocked.

[0004] However, the utility model has the following problems when actually used:

[0005] When the utility model is actually used, there is no device to control and fix the patient's hand. The patient may experience unconscious shaking of the hand due to psychological factors such as tension and anxiety. When shaking, the hand may break and fall off, causing the needle to slip.

[0018] (3) Beneficial effects

[0019] The utility model provides a restraint belt for fixing the upper limbs of patients with arteriovenous fistula puncture, which has the following beneficial effects:

[0020] The restraint belt for fixing the upper limbs of patients undergoing arteriovenous fistula puncture is configured by cooperating with a hand plate, an elastic band, and a finger cot, so that the device can fix the position of the patient's hand. By fixing the patient's hand, the puncture needle can be ensured to remain stable during the dialysis process, and the puncture needle can be reduced from coming out or shifting due to shaking of the patient's hand position, thereby ensuring the safety of the patient during hemodialysis and improving the overall nursing quality of hemodialysis. For patients who need to undergo hemodialysis for a long time, hand fixation can make them feel more at ease and reduce the anxiety caused by the worry about the puncture needle shifting. For older patients or patients with reduced hand control due to illness, hand fixation can ensure their safety during the dialysis process. BRIEF DESCRIPTION OF THE DRAWINGS
