Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a thumb brace. Background Technology
[0002] After a thumb injury or disease (such as tenosynovitis), a thumb brace may be needed to immobilize and protect the thumb, preventing thumb movement from affecting its recovery. In the prior art, thumb braces typically include a main body, support strips, and several straps. For example, patent CN210077987U discloses a thumb wrist brace including a main body and a knob-and-strap system. The main body has a cylindrical structure, and the knob-and-strap system is located on the front of the main body, connecting the left and right ends for adjusting the tightness. The main body includes a thumb protection device connected to the right end of the main body. Vertical support strips are provided on the middle and right side of the back of the main body. The support strip on the right side of the main body extends from the bottom to the thumb protection device. The support strip is made of aluminum alloy. The support strip has an arc shape, designed to conform to the skeletal structure of the human wrist joint and thumb, allowing for better fit, fixation, and support of the wrist and thumb. The drawback of existing thumb braces is that the support bar is placed on the back of the thumb, while the thumb is fixed to the palm side by a strap. The disadvantage of this approach is that, based on the structural characteristics of the thumb joint, the thumb moves from an open palm towards the center of the hand. Therefore, the support bar on the back of the hand cannot prevent the thumb from moving directly, resulting in poor fixation and a certain range of motion for the user's thumb. This range of motion can affect the recovery of the thumb, so improvements are needed. Summary of the Invention
[0003] The purpose of this invention is to solve the problem in existing thumb protectors where the support strip is located on one side of the back of the hand and cannot prevent thumb movement from the front, resulting in poor thumb fixation. This invention provides a thumb protector.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A thumb brace includes a brace body and a support frame. The support frame is fixedly installed in the brace body. The support frame includes a first curved surface that conforms to the contour of the palm side of the thumb, a second curved surface that conforms to the thenar eminence and the middle of the palm, and a third curved surface that conforms to the wrist. A fixing part for fixing the thumb is provided at the front end of the brace body. The fixing part is located at the front end of the first curved surface of the support frame. A thumb strap is provided on the outside of the fixing part.
[0005] In the above-described design, the protective gear body includes a support portion and positioning portions disposed on both sides of the support portion, with the support frame housed within the support portion. This design allows the support portion of the protective gear body to support the patient's thumb, palm, and wrist joints, while the positioning portions on both sides can wrap and fix the brace from both sides, making the thumb brace more stable.
[0006] 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.
[0007] 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 thumb, palm, and wrist joint, 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.
[0008] In the above solution, an elastic connecting fabric is provided on the inner side of the fixing part, and a thumb receiving cavity is formed between the elastic connecting fabric and the fixing part to accommodate the thumb. By providing an elastic connecting fabric in the fixing part, it is convenient to initially wrap the thumb, and it is convenient to further fix the thumb subsequently using thumb straps and thumb-mouth straps.
[0009] In the above-described design, the protective gear body is further equipped with a thenar eminence strap and a wrist strap. The thenar eminence strap is positioned corresponding to the thenar eminence of the palm, and the thenar eminence strap and wrist strap are fixed in opposite directions. This design allows for separate fixation at the thenar eminence and wrist positions, making the protective gear more stable. The opposite direction of the thenar eminence strap and wrist strap allows for tightening from two opposite directions, resulting in a more secure fit.
[0010] In the above solution, both the wrist strap and the forefinger strap are equipped with Velcro, and the protective gear body has fixing rings corresponding to the forefinger strap and the wrist strap, respectively. By using Velcro, the connection between the wrist strap and the forefinger strap is made easier, and by using fixing rings, the straps can be guided and limited to prevent misalignment, and the wrist strap can be fixed more securely.
[0011] This invention has several advantages: The thumb brace of this invention features a support frame designed with a curved surface based on the shape of the palm side of the human hand. The support frame includes a first curved surface that conforms to the contour of the palm side of the thumb, a second curved surface that conforms to the thenar eminence and the middle of the palm, and a third curved surface that conforms to the wrist. This design extends the support frame from the thumb towards the middle of the palm, covering the thenar eminence, then to the middle of the palm, and finally to the wrist joint. This design fully considers the structural characteristics of the thumb joint, which bends towards the palm side. Therefore, the support frame provides stable support and fixation for the patient's thumb, palm, and wrist joint. Compared to existing thumb braces that fix the thumb from the back of the hand, this design offers more stable fixation and is more conducive to the recovery of the thumb bones.
