AI Technical Summary
Existing wrist binding restraints pose a risk of compression and obstruction to the wrist fistula blood vessels of hemodialysis patients, which may lead to reduced blood flow, decreased fistula function or even occlusion, affecting the dialysis effect and the life of the fistula.
A palm-fixed restraint was designed, which fixed the thenar, tiger's mouth, hypothenar and finger gaps of the palm with a fixing rope. A tightener and spring component structure was used to form a stable fixing network to avoid direct compression of the internal fistula. The elastic clamping mechanism of the spring component was used to prevent the rope from loosening.
It can effectively fix the palm without affecting the blood flow of the internal fistula, improve the dialysis effect, extend the service life of the internal fistula, and reduce the risk of skin damage. It is suitable for patients with newly-created internal fistulas and agitated patients to ensure the safety of treatment.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a palm fixed type improved restraint. BACKGROUND
[0002] Hemodialysis patients need to undergo arteriovenous fistula surgery, and the surgical site is usually on the radial side of the wrist. This internal fistula is formed by directly connecting the artery and vein, forming a high-flow, low-resistance vascular access. For new dialysis patients and restless patients, to prevent needle hematoma or needle loss, in addition to reinforcement and fixation, restraint is also needed to ensure dialysis safety.
[0003] However, most of the restraint fixers on the market currently use wrist binding fixation methods, which have serious problems. Wrist binding may compress the internal fistula blood vessels, causing reduced or blocked blood flow. Long-term use may cause internal fistula function to decline, and even cause internal fistula occlusion or thrombosis. This not only affects the dialysis effect, but also may cause the internal fistula to fail, requiring another surgery to establish a new internal fistula.
[0004] Therefore, it is necessary to make further improvements. CONTENT OF THE UTILITY MODEL

[0008] In one or more embodiments, the base is provided with a spring member abutting against the operating part, and under normal circumstances, the spring member lifts the operating part and makes the rope passing hole dislocated from the rope channel.
[0009] In one or more embodiments, at least a part of the operating part protrudes from the base under the action of the spring member.
[0010] In one or more embodiments, the base is provided with a positioning column for the spring member to be sleeved on, and the operating part is provided with a recess cavity for the spring member to extend into.

If the first, the second are described, it is only used for distinguishing technical features for the purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.
[0021] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
[0022] In this utility model, unless otherwise expressly defined, terms such as "disposed," "installed," and "connected" should be interpreted broadly. For example, they may refer to direct connection or indirect connection through an intermediate medium; fixed connection or detachable connection or integral molding; mechanical connection; internal communication between two components or interaction between two components.

[0023] Please see Figures 1-4 The present application provides an improved palm-fixing restraint, which includes a tightener and several fixing ropes 1. The several fixing ropes are connected to the tightener and tightened through the tightener. The fixing ropes are used to be sleeved on the palm of the human body. Specifically, the fixing ropes are tightened on the thenar eminence, tiger's mouth, hypothenar eminence and finger gaps of the palm to form a stable fixing network, ensuring that the fixing ropes fit the contour of the hand to ensure the fixing effect and comfort. The fixing ropes sleeved on the palm are tightened by pulling the end of the fixing rope connected to the tightener. After tightening, the fixing ropes are fixed by the tightener to prevent the fixing ropes from loosening, thereby completing the fixation of the palm.
[0024] The tightener includes a base 2 and an operating part 3. The base is provided with a rope path 4 for the fixing rope to pass through. The operating part 3 is movably mounted on the base and is provided with a rope hole 5. The operating part can be moved relative to the base to make the rope hole correspond to or be misaligned with the rope path. When tightening the fixing rope, the medical staff first controls the operating part to make the rope control correspond to the rope path. Then, after tightening the fixing rope, the medical staff operates the operating part again to make the rope hole and the rope path misaligned, thereby clamping the fixing rope to prevent the fixing rope from loosening.
[0025] In order to further simplify the operation process of the tightener, a spring member 6 is provided on the base 2 to abut against the operating part 3. Under normal circumstances, the spring member lifts the operating part and causes the rope hole 5 to be misaligned with the rope path 4. Therefore, when it is necessary to tighten the fixed rope, the medical staff first presses the operating part to compress and deform the spring member, and at the same time, the rope hole and the rope path correspond to each other, and then tighten the fixed rope. After the fixed rope is tightened, the pressure on the operating part is released, and the spring member quickly recovers its deformation, causing the rope hole and the rope path to be misaligned, thereby clamping the fixed rope to prevent it from loosening.
[0026] In order to facilitate the medical staff to press the operation part, the operation part 3 is at least partially protruding from the base 2 under the action of the spring member 6.
[0027] The base 2 is provided with a positioning column 7 for the spring member 6 to be sleeved, and the operation part 3 is provided with a recess cavity 8 for the spring member to extend into, and the positioning column and the recess cavity are used for positioning the spring member, avoiding displacement, distortion and other problems of the spring member in compression or normal state.
[0028] The bottom of the tightener is provided with a soft gasket 9, the tightener is located at the middle position of the soft gasket, the soft gasket 9 is adhesively fixed with the bottom of the tightener, and the soft gasket can adopt a sponge block or other elastic or soft rubber pad, so as to improve the comfort of the restraint device in use.
[0029] The plurality of fixing ropes 1 pass through the tightener and are connected with a thread organizer 10, the thread organizer can collect and arrange each fixing rope, avoiding mutual entanglement and knotting of the fixing ropes.
[0030] The restraint device of the present application avoids the direct compression of the traditional wrist binding on the arteriovenous fistula (AVF), effectively protects the hemodynamics of the vascular access; by dispersing the stress points, the local pressure is reduced, the risk of skin damage and pressure sores is reduced, a more stable fixing effect is provided, and accidental needle removal during hemodialysis is effectively prevented. The fixing method is not only suitable for conventional hemodialysis patients, but is especially beneficial for newly built fistula patients and patients with agitation tendency, which can maximize the protection of fistula function while ensuring treatment safety, prolong the service life of the fistula.
[0031] Of course, the utility model is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent transformations or replacements without departing from the spirit of the utility model, and these equivalent transformations and replacements are all included in the range defined by the claims of the present application.
