Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a wrist brace. Background Technology

[0002] After a wrist injury or illness, a wrist brace may be needed to immobilize and protect the wrist, preventing wrist movement from affecting recovery. In the prior art, wrist braces typically include a wrist guard, an aluminum backplate and a aluminum palmplate, and straps. For example, patent CN 209500727 U discloses a well-fitting wrist brace, specifically a well-fitting wrist brace including a wrist guard with an arm opening at the bottom, a finger opening at the top, a thumb opening on one side, a first pocket sewn onto the back of the wrist guard, and a second pocket sewn onto the palm. Both the first and second pockets have openings on their surfaces. The first pocket contains the aluminum backplate, and the second pocket contains the aluminum palmplate. A main strap is sewn onto the surface of the wrist guard, with a first strap and a second strap sewn onto both sides of the main strap. When using it, first insert the wristband through the opening on the forearm, with the thumb protruding from the thumb opening and the other four fingers protruding from the finger openings. Then, place the aluminum piece from the back of the hand into the opening of the first sleeve, and secure it together with the internal fastener through the first fixing hole. Next, place the aluminum piece from the palm into the opening of the second sleeve, and secure it together with the internal fastener through the second fixing hole. Then, use the first strap to secure the second sleeve, and use the second strap to secure the first sleeve. Finally, use the main strap to wrap around the wristband and secure it.

[0003] The disadvantages of the aforementioned wrist brace are that its structure is complex, requiring two aluminum plates for wrist fixation. Ensuring that both aluminum plates fit snugly against the wrist joint is quite difficult. Furthermore, the palm and back aluminum plates are placed in a pouch during wear and secured with a fixing hole and buckle. This method of fixation restricts the movement of the palm and back aluminum plates, making it difficult for them to fit snugly against the patient's wrist joint. Therefore, the existing wrist brace needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of complex structure and poor fit of existing wrist braces, and to provide a wrist brace.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A wrist brace includes a brace body and a support frame. The support frame is fixedly installed in the brace body. The brace body has a thumb hole corresponding to the user's thumb. The support frame includes a first curved surface corresponding to the palm of the human body, a second curved surface corresponding to the wrist joint of the human body, and an extension extending along the wrist to the arm. The first curved surface is located next to the thumb hole. The second curved surface is an arc-shaped protrusion that matches the shape of the base of the human hand. A brace fixing member is provided on the outer surface of the brace body.

[0006] In the above scheme, the protective gear fixing component is a palm fixing component provided at the front end of the protective gear body. The position of the palm fixing component corresponds to the position of the first curved surface of the supporting frame. A wrist fixing component is provided on the protective gear body at the part corresponding to the wrist.

[0007] In the above solution, the brace fastener is a knob, which is fixedly mounted on the outer surface of the brace body. Multiple rope-locking buckles are located on the outer surface of the brace body, and rope is wound along a curve between these rope-locking buckles, with the end of the rope connected to the knob. This design allows for easy tightening and loosening of the wrist brace simply by rotating the knob. Furthermore, the rope applies even pressure to the brace body along the curve, resulting in a more uniform tightening force on the outside of the brace and more suitable pressure on the patient's wrist.

[0008] In the above-described design, the protective gear body includes a support portion and positioning portions disposed on both sides of the support portion. The support frame is disposed within the support portion, and the palm fixation component and wrist fixation component are respectively fixedly disposed on the positioning portions. With this design, the support portion of the protective gear body can support the patient's palm and wrist joint, while the positioning portions on both sides can wrap and fix the wrist joint from both sides, making the fixation of the patient's wrist joint more stable and preventing positional shift during wear.

[0009] In the above solution, the hand fixing component includes a fixing ring and a strap. The fixing ring is fixedly mounted on a positioning part on one side of the support, and the strap is fixedly mounted on a positioning part on the other side. By setting the fixing ring and the strap, and placing them on different sides of the support, when fixing with the strap, the strap is first passed through the fixing ring, and then pulled tight in the opposite direction. The fixing ring can guide and limit the strap, preventing it from shifting, and making the strap more secure.

[0010] In the above solution, the wrist fixation components are provided in several groups, each group including a fixing ring and a strap. Different groups of wrist fixation components are set on the positioning parts on different sides of the protective gear body. For example, two groups of wrist fixation components can be set, one group is set on the positioning part on the left side of the support part of the protective gear body, and the other group is set on the positioning part on the right side of the support part. By tightening the two groups of wrist fixation components in opposite directions, the positioning of the wrist can be more stable.

[0011] In the above solution, both the palm fixation component and the wrist fixation component have Velcro straps. The Velcro straps facilitate securing the straps.

[0012] In the above solution, an elastic connecting fabric is provided between the positioning parts on both sides of the support, and the elastic connecting fabric and the protective gear body form a receiving cavity to accommodate the palm and wrist. By setting the elastic connecting fabric, it is easier to wear the protective gear. When wearing it, the patient can first put their hand into the receiving cavity, and the elastic fabric can form an initial wrap around the patient's palm and wrist joint, so that it can be further fixed by the straps.

[0013] In the above solution, the protective gear body has an elastic protective layer inside, ventilation holes on the inner wall of the protective gear body, and ventilation holes distributed on the surface of the supporting frame. By setting the elastic protective layer, protection can be provided for the palm and wrist joints, while the ventilation holes on the protective gear body and supporting frame can ensure the breathability of the protective gear, making it more comfortable to wear.

[0014] This invention has several positive effects: The wrist brace of this invention has a simple structure and is easy to use. The supporting frame is designed with a curved surface according to the shape of one side of the human palm. The frame includes a first curved surface corresponding to the palm, a second curved surface corresponding to the wrist joint, and an extension extending from the wrist to the arm. The first curved surface supports the user's palm and restricts the bending of the palm to one side. The second curved surface is an arc-shaped protrusion that matches the shape of the base of the palm, allowing for precise fit and positioning of the base of the palm. The extension extends along the wrist to the straight arm. Therefore, the wrist brace of this invention provides stable support and fixation from the patient's palm to the arm, inhibiting bending movements of the wrist joint and promoting the recovery of the wrist bones.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below through embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 and 2 As shown, the wrist brace of this utility model includes a brace body 1 and a support frame 2.

[0022] The protective gear body 1 is made of breathable fabric. It can be made of a fabric with a certain degree of elasticity, and an elastic protective layer can be set inside the protective gear body 1 to protect the palm and wrist joints.

[0023] Ventilation holes can also be provided on the inner wall of the protective gear body 1. By providing ventilation holes on the protective gear body 1, the breathability of the protective gear can be ensured, making it more comfortable to wear.

[0024] The protective gear body 1 includes a support portion 11 and positioning portions 12 disposed on both sides of the support portion 11. The support frame 2 is disposed inside the support portion 11. The support portion 11 has thumb holes 13 corresponding to the user's thumb. The palm fixation component and the wrist fixation component are respectively fixedly disposed on the positioning portions 12. The support portion 11 of the protective gear body 1 can be used to support the patient's palm and wrist joint, while the positioning portions 12 on both sides can wrap and fix from both sides, making the fixation of the patient's wrist joint more stable and preventing positional displacement during wearing.

[0025] An elastic connecting fabric is provided between the positioning parts 12 on both sides of the support part 11, forming a receiving cavity between the elastic connecting fabric and the protective gear body 1 to accommodate the palm and wrist. By providing the elastic connecting fabric, it is easier to wear the protective gear. When wearing it, the patient can first put their hand into the receiving cavity, and the elastic fabric can form an initial wrap around the patient's palm and wrist joint, so that it can be further fixed by the protective gear fixing parts.

[0026] Protective gear fasteners are provided on the outer side of the protective gear body 1. The protective gear fasteners can be selected as needed, for example, straps or buckles can be used as protective gear fasteners.

[0027] like Figure 3 As shown, the support frame 2 can be a one-piece injection molded part. The support frame 2 includes a first curved surface 21 corresponding to the palm of the human body, a second curved surface 22 corresponding to the wrist joint of the human body, and an extension 23 extending along the wrist to the arm. The support frame 2 is longitudinally sewn into the support part 11, and the first curved surface 21 is located next to the thumb hole 13. After the user's thumb passes through the thumb hole 13, the palm is exactly located at the position of the first curved surface 21. The second curved surface 22 is an arc-shaped protrusion that matches the shape of the base of the human hand. The arc-shaped protrusion faces the palm side, while the side of the user's palm is an arc-shaped concave surface. The base of the palm has a corresponding protruding shape. Through this design, the support frame 2 can better fit the human body.

[0028] Ventilation holes 24 are provided on the surface of the support frame 2, which can improve the breathability of the wrist brace.

[0029] The structure of the support frame 2 of this utility model is suitable for both the left and right hands of the human body, so there is no need to consider the difference between the left and right hands during assembly, and it is set in the corresponding protective body 1. Figure 3 The diagram shows a structural schematic of a wrist brace for the right hand. In practical applications, the main difference between a wrist brace for the left hand and a wrist brace for the right hand lies in the relative positions of the thumb hole 13 and the support frame 2. During manufacturing, only symmetrical arrangement is required.

[0030] Multiple ventilation holes 24 are distributed on the support frame 2. The ventilation holes 24 improve the breathability of the wrist brace.

[0031] like Figure 1 and 2As shown, in the first embodiment of the protective gear fixing component of this utility model, a palm fixing component 31 is provided at the front end of the protective gear body 1. The position of the palm fixing component 31 corresponds to the position of the first curved surface 21 of the support frame 2. The palm fixing component 31 includes a fixing ring 32 and a strap 31. The fixing ring 32 is fixedly disposed on the positioning part 12 on one side of the support part 11, and the strap 31 is fixedly disposed on the positioning part 11 on the other side. By setting the fixing ring 32 and the strap 31, and the strap 31 and the fixing ring 32 are respectively disposed on different sides of the support part 11, when fixing with the strap 31, the strap 31 is first passed through the fixing ring 32, and then pulled tight in the opposite direction to fix it. The fixing ring 32 can guide and limit the strap 31 to prevent it from being misaligned, and can make the fixing of the strap 31 more secure.

[0032] A wrist fixing component 4 is provided on the protective gear body 1 at the location corresponding to the wrist. Several sets of wrist fixing components 4 are provided, each set including a fixing ring and a strap. Different sets of wrist fixing components 4 are located on positioning parts 12 on different sides of the protective gear body 1. The arrangement of the wrist fixing components can be selected as needed. For example, two sets of wrist fixing components can be provided: one set is located on the positioning part on the left side of the support part of the protective gear body, and the other set is located on the positioning part on the right side of the support part. By tightening the two sets of wrist fixing components in opposite directions, the wrist positioning can be more stable. During installation, the fixing ring and strap of each set of wrist fixing components are fixed on the positioning part on the same side of the support part. When fixing the strap, the strap can be wrapped around the outside of the protective gear body once, then passed through the fixing ring, then pulled tight in the opposite direction, and then fixed with Velcro. The wrist fixing component 4 can also be arranged in the same way as the palm fixing component, with the fixing ring on one side of the positioning part and the strap on the other side of the positioning part. Two sets of wrist fixation components can be set. The fixing ring of one set of wrist fixation components is set on the positioning part on the left side of the support part of the protective gear body, and the strap is set on the positioning part on the right side of the support part. The fixing ring of the other set of wrist fixation components is set on the positioning part on the right side of the support part of the protective gear body, and the strap is set on the positioning part on the left side of the support part. Through this reverse binding and fixing, the wrist positioning can be more stable.

[0033] Both the hand fixation component 3 and the wrist fixation component 4 have Velcro straps. The Velcro straps make it easier to secure the straps.

[0034] like Figure 4As shown, in a second embodiment of the wrist brace fastener of this utility model, the fastener is a knob 5. The knob 5 can be an existing knob, simply connected to the end of the binding rope 6 in the existing manner. When setting the knob 5, the binding rope limiting buckles 7 can be respectively set on the positioning portions 12 on both sides of the support portion 11 of the brace body 1. The binding rope 6 is preferably an elastic binding rope 6, which can be arranged along an approximately S-shaped curve between the binding rope limiting buckles 7 on both sides of the positioning portions 12. The knob 5 is fixedly set on the outer surface of the brace body 1 and located in the middle of the binding rope 6. Both ends of the binding rope 6 are fixedly connected to the knob 5. Tightening and loosening the wrist brace can be completed by rotating the knob 5. The operation is very simple, and by applying pressure evenly to the brace body along the curve of the binding rope, the tightening force on the outside of the brace body is more uniform, making the pressure on the patient's wrist more moderate.

[0035] This invention relates to a wrist brace. When in use, the patient selects either the left or right wrist brace according to their needs. The patient inserts their palm into the cavity between the elastic connecting fabric and the brace body, then inserts their thumb into the thumb hole, aligning the palm with the first curved surface of the supporting frame. Simultaneously, the base of the palm fits against the second curved surface of the supporting frame, with the extension naturally extending to the arm. The hand straps on the outside of the brace body are then passed through the corresponding fixing rings and pulled back, secured with Velcro. The wrist straps are then secured in sequence. After securing, the palm side of the hand receives effective support, restricting palm movement towards the palm. Furthermore, the hand and wrist straps effectively limit wrist movement, inhibiting flexion of the wrist joint and promoting wrist bone recovery.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
