Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a restraint device for arteriovenous fistula patients undergoing hemodialysis. Background Technology
[0002] Arteriovenous fistulas (AVFs) in hemodialysis are vital vascular access points for maintaining the lives of hemodialysis patients. They surgically connect an artery and a vein, providing a stable and sufficient blood supply for dialysis treatment. However, during dialysis, the patient's hand movements can accidentally impact or compress the fistula site, potentially leading to serious complications such as thrombosis, stenosis, or occlusion. Therefore, to protect the integrity and function of the fistula, ensure the smooth progress of dialysis treatment, and improve patient comfort, the use of restraints to limit the patient's hand movement is crucial. Proper use of restraints can effectively reduce the adverse effects of the patient's hand on the fistula site, ensuring the safety and effectiveness of dialysis treatment.
[0003] However, existing glove-type restraints are all applied to the wrist, and the restraint position is too high, causing them to slide up and down during use, which can easily lead to occlusion of arteriovenous fistulas in the forearm of hemodialysis patients. Furthermore, most existing glove-type restraints are disposable, and the materials are not easy to sterilize and cannot be recycled. Additionally, existing glove-type restraints are designed with five fingers spread apart, making them inconvenient for patients with different hand shapes. Therefore, this application proposes a restraint device for hemodialysis patients with arteriovenous fistulas to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a restraint device for arteriovenous fistula patients undergoing hemodialysis, thereby solving the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a restraint device for arteriovenous fistula patients undergoing hemodialysis, comprising a restraint sleeve body, a limiting groove being formed on the rear side wall of the restraint sleeve body, a first limiting band, a second limiting band, and a binding band being provided below the limiting groove, both ends of the first limiting band and the second limiting band being fixedly connected to the outer side wall of the restraint sleeve body, the binding band being located inside the first limiting band, the second limiting band being located in front of the first limiting band, and an external fixing band being provided inside the second limiting band.
[0006] Preferably, two auxiliary limiting bands are fixedly connected to the outer side wall of the constraint sleeve body. Both auxiliary limiting bands are fixedly connected to the outer side wall of the constraint sleeve body, and the two auxiliary limiting bands are symmetrically arranged on both sides of the limiting groove.
[0007] Preferably, two pipe adjustment bands are fixedly connected to the side of the outer wall of the constraint sleeve body away from the auxiliary limiting band, and the two pipe adjustment bands are connected to the constraint sleeve body at the left and right sides of the limiting groove, respectively.
[0008] Preferably, the main body of the constraint sleeve is made of a soft material.

The main body of the restraint sleeve adopts a tubular structure, and the four fingers of the finger part are connected, which can be adapted to different hand shapes, greatly improving the practicality of the device. At the same time, the device is equipped with a tube opening adjustment strap, which allows for adjustment of the size of the front port of the restraint sleeve main body through the connection of two tube opening adjustment straps, thereby improving the device's restraint effect on the patient's hand position. In addition, the binding strap, external fixation strap and restraint sleeve main body of this device are all detachable, which facilitates disinfection and sterilization, thereby enabling the device to be reused and reducing the economic burden on patients.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a restraint device for hemodialysis patients with arteriovenous fistulas, including a restraint sleeve body 1. A limiting groove 2 is opened on the rear side of the side wall of the restraint sleeve body 1. A first limiting band 6, a second limiting band 7, and a binding band 4 are arranged below the limiting groove 2. Both ends of the first limiting band 6 and the second limiting band 7 are fixedly connected to the outer side wall of the restraint sleeve body 1. The binding band 4 is located inside the first limiting band 6, and the second limiting band 7 is located in front of the first limiting band 6. An external fixing band 5 is arranged inside the second limiting band 7. The device is bound to the patient's hand using the binding band 4, and then fixedly connected to the patient's bed using the external fixing band 5. This provides a good restraint effect on the device and the patient's hand, and also prevents the device from moving during use, thus preventing the arteriovenous fistula in the forearm of the hemodialysis patient from becoming blocked.
