Description

Technical Field

[0001] The utility model relates to the technical field of fixing braces, in particular to a fixing brace for a middle finger or a ring finger. Background Art

[0002] As a supporting device placed outside the body, a fixation brace has the function of limiting the movement of specific parts of the body. Based on this, in the medical and related fields, fixation braces are usually used to assist surgical treatment, such as using fixation braces to fix the position of the radiotherapy site during radiotherapy; or, it can also be directly used for external fixation of non-surgical treatment, such as using fixation braces to fix the fracture site during fracture rehabilitation. With the development of the market and the advancement of technology, more and more fixation braces have begun to use plastic low-temperature thermoplastic plate materials, which are more practical than traditional plaster or hard plastic materials in fixation braces. When in use, the fixation brace made of low-temperature thermoplastic plate material is placed in hot water for heating and softening, and then its shape can be adjusted as needed so that it can fit on specific parts of the human body. Then, after standing at room temperature for a few minutes, it will harden and become plastic, thus forming a fixation effect.

[0003] The hand is an important part of the human body for maintaining daily life and is often in an active state. Among them, the middle finger and ring finger of the hand are more fragile due to their relatively slender bones, which makes them prone to fractures when impacted by external forces. They are also prone to joint pain and other lesions. Therefore, the middle finger and ring finger need to use special fixation braces to assist in radiotherapy and fracture rehabilitation (it should be noted that this application does not deny that other fingers and parts of the hand also have this need, but this application is mainly for the middle finger and ring finger).

[0004] However, most traditional low-temperature thermoplastic plate fixation braces are in the form of flat diaphragms, which need to be plasticized on site according to the shape of the treatment site during use; for example, the Chinese patent with announcement number CN208243930U provides a radiotherapy positioning membrane (in the field of radiotherapy, a fixation brace made of low-temperature thermoplastic plate material is usually called a radiotherapy positioning membrane), which includes a positioning membrane formed by a low-temperature thermoplastic plate diaphragm; this flat diaphragm form has no support of any basic shape, and the shape of the middle finger and ring finger is relatively three-dimensional and complex, so it is more difficult to plasticize, resulting in more energy and time; and for general users (i.e. users who have not specially studied and practiced shaping operations), it is easy to have inadequate shaping or even failure. In the current market, although there are some fixation braces with basic shapes, most of them are suitable for large areas of the human body such as the head, legs, and hands, and there is a lack of special fixation braces for specific parts such as the middle finger and ring finger.

[0005] In summary, it is very necessary to propose a fixation brace for the middle finger or ring finger. Utility Model Content

[0006] The purpose of the utility model is to provide a fixing brace for the middle finger or the ring finger, so as to solve the problem mentioned in the above background technology that there is a lack of special fixing braces for the middle finger and the ring finger in the prior art.

[0007] The utility model is realized by adopting the following technical solutions:

[0008] A fixing brace for a middle finger or a ring finger, comprising a positioning film and a fixed frame arranged around the outer edge of the positioning film, wherein the positioning film is made of a low-temperature thermoplastic plate, and a plurality of mesh holes are provided on the positioning film, wherein the positioning film comprises a finger area and a metacarpophalangeal joint area which are integrally connected and formed, wherein the finger area is located above the metacarpophalangeal joint area; the shape and size of the finger area are adapted to the shape and size of the middle finger and the ring finger of the human body, and the shape and size of the metacarpophalangeal joint area are adapted to the shape and size of the metacarpophalangeal joint area of ​​the human body; the metacarpophalangeal joint area is divided into area I, area II and area III, wherein area I is located below the finger area, and areas II and III are located on both sides of area I, respectively, and the size ratio of area II to area III is 1:2.

[0009] Furthermore, the finger area is a hollow cylindrical shape with upper and lower openings, and the metacarpophalangeal joint area is a hollow rectangular parallelepiped shape with upper and lower openings.

[0010] Furthermore, the finger area is a non-enclosed surrounding structure, and an opening I with adjustable width is provided in the finger area, and the width of the opening I is directly proportional to the size of the finger area.

[0011] Furthermore, the metacarpophalangeal joint area is a non-enclosed surrounding structure, and an opening II with adjustable width is provided in the metacarpophalangeal joint area, and the width of the opening II is directly proportional to the size of the metacarpophalangeal joint area.

[0012] Furthermore, the fixed frame is made of a soft strip material.

[0013] Furthermore, the outer surface of the fixed frame is covered with fluff, and the inner surface of the fixed frame is provided with adhesive.

[0014] In the present invention, by providing a finger area that matches the shape and size of the middle finger and ring finger of the human body, and a metacarpophalangeal joint area that matches the shape and size of the metacarpophalangeal joint area of ​​the human body, the fixed brace can be worn on the user's hand and the user's middle finger or ring finger can be fixed in a limited position. The metacarpophalangeal joint area is provided to achieve the wearing effect. If there is only the finger area, the fixed brace cannot be worn on the hand, which will cause the finger area to fall off easily; and the metacarpophalangeal joint area can also limit the movement of the metacarpophalangeal joint to a certain extent, thereby limiting the overall movement of the finger. Specifically, the following points need to be explained in particular:

[0015] First, the fixation brace proposed in the above scheme cannot limit the middle finger and the ring finger at the same time, but can be applied to the middle finger or the ring finger according to the actual situation; this is because in actual application, there are few cases where two fingers are fractured or diseased at the same time, and usually only one of the fingers needs to be limited. Based on this, the shape and size of the finger area in the fixation brace actually needs to be close to the average or maximum value of the shape and size of the middle finger and the ring finger (due to its thermoplasticity, it can be fine-tuned during use, so the original shape and size only need to be close).

[0016] Secondly, when the fixed brace is used to limit the middle finger, the middle finger is limited when it is inserted into the finger area, the index finger extends from the area II with a proportion of 1, and the ring finger and the little finger extend from the area III with a proportion of 2; compared with the state when it is used to limit the middle finger, the fixed brace can be used to limit the ring finger after turning it 180°, at which time the ring finger is limited when it is inserted into the finger area, the little finger extends from the area II with a proportion of 1, and the middle finger and the index finger extend from the area III with a proportion of 2. It can be imagined that in actual production, by adjusting the number and / or position of the finger area, and adjusting the distribution mode and proportion of different areas below the finger area accordingly, the limitation of different fingers can be achieved; for example, the finger area is set at the upper part of one end of the metacarpophalangeal joint area, and the area below the finger area forms a ratio of 1:3 with the remaining area of ​​the metacarpophalangeal joint area, so that the limitation of the index finger or the little finger can be achieved.

[0017] Third, by providing openings I and / or II with adjustable widths, the adjustment of the shape and size of the fixed brace during plasticization is simpler and more convenient, and the fixed brace is convenient to wear and remove. By providing the fixed frame with a soft strip material, it is easy to adapt to the shape and size changes of the positioning film. By covering the outer surface of the fixed frame with fluff, the user's comfort can be increased; and by providing adhesive on the inner surface of the fixed frame, it is easy to connect the fixed frame to the outer edge of the positioning film.

[0018] The beneficial effects achieved by the utility model are:

[0019] The utility model provides a fixing brace for the middle finger or the ring finger, which can be worn on the user's hand and limit the position of the user's middle finger or the ring finger; compared with the traditional flat diaphragm and the existing fixing brace with a basic shape, the fixing brace has a specific basic shape, which can be specially adapted to the middle finger / ring finger and the metacarpophalangeal joint area of ​​the human body, filling the gap in the current market for the lack of special fixing braces for the middle finger and the ring finger. Based on this, when using the fixing brace, it is only necessary to make slight adjustments to the shape and size of the fixing brace with the help of thermoplasticity, so that it can be well adapted to the user's hand; the operation is simple and quick, and even ordinary users can easily achieve a good shaping effect, thereby effectively ensuring the limiting and fixing effect of the fixing brace.
