Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a fixing brace. Background Art

[0002] An external skeletal fixation brace is an external fixation brace that is generally installed on the limbs, trunk and other parts of the human body. It is used to prevent or correct deformities of the limbs or trunk, treat bone and joint diseases, and promote bone and joint healing during postoperative repair.

[0003] Plaster is widely used to fix fractures during postoperative healing because it is easily accessible, inexpensive, and possesses excellent plasticity and sufficient strength. During plaster fixation, the plaster is placed over the patient's fracture site to fix it, preventing displacement and allowing the fracture to heal through the body's own tissue metabolism. While this plaster fixation technique achieves fixation of the fracture site, it is not breathable, making it extremely susceptible to bacterial growth on the patient's skin, which can lead to skin ulcers. Plaster also presents challenges such as being cumbersome to manufacture, being heavy, and being impervious to water. Utility Model Content

[0004] The utility model aims to solve the problems of airtightness and heaviness of plaster fixation of fractured bones. The utility model provides a fixation brace that is light and breathable.

[0047] refer to Figure 1 The present embodiment provides a fixation brace 1 for fixing a part of a user that needs to be fixed (e.g., a fracture). Those skilled in the art will appreciate that the user of the fixation brace 1 can be a human or other animal. This embodiment is described using the fixation brace 1 for fixing a human fracture as an example.

[0048] like Figure 1 and Figure 2 As shown, Figure 2 A schematic diagram shows the first housing portion 220 and the second housing portion 230 in a separated state. The fixation brace 1 includes a first flexible member 2 and a second flexible member 3. The first flexible member 2 includes a first housing portion 220 and a second housing portion 230. The first housing portion 220 and the second housing portion 230 are connected to form a hollow chamber 20. The hollow chamber 20 is a closed chamber for pouring curable material.

[0049] In this embodiment, the first housing portion 220 includes a plurality of interconnected first grooves 221, and the second housing portion 230 includes a plurality of interconnected second grooves 231. The second grooves 231 and the first grooves 221 are arranged opposite to each other in the thickness direction Z of the first flexible member 2 and correspond one to one. The second housing portion 230 covers the first housing portion 220 to form a hollow chamber 20 between the first housing portion 220 and the second housing portion 230. That is, the first housing portion 220 and the second housing portion 230 are symmetrical in vertical direction. When the two are covered together, the second grooves 231 and the first grooves 221 are connected in vertical direction, forming a closed hollow chamber 20 for accommodating the curable material.

[0050] Those skilled in the art will appreciate that in other embodiments, Figure 3As shown in FIG, a schematic diagram of a state in which the first housing portion 220 and the second housing portion 230 are separated is shown. A plurality of first grooves 221 communicating with each other can be provided only in the first housing portion 220, and the second housing portion 230 is in the shape of a plate, and the second housing portion 230 covers the first housing portion 220 to form a hollow chamber 20 between the first housing portion 220 and the second housing portion 230, that is, the curable material is contained in the first groove 221. Alternatively, Figure 4 As shown, a schematic diagram of the state in which the first shell part 220 and the second shell part 230 are separated is shown, and a plurality of second grooves 231 interconnected with each other are provided only in the second shell part 230. The first shell part 220 is in the shape of a plate, and the first shell part 220 covers the second shell part 230 to form a hollow chamber 20 between the first shell part 220 and the second shell part 230, that is, the curable material is accommodated in the second grooves 231.

[0051] In this embodiment, the first housing portion 220 and the second housing portion 230 are integrally formed. However, those skilled in the art will appreciate that in other embodiments, the first housing portion 220 and the second housing portion 230 may be connected by bonding, ultrasonic welding, or the like.

[0052] like Figure 1 and Figure 5 As shown, the first flexible member 2 includes a plurality of vent holes 21, which penetrate the first housing portion 220 and the second housing portion 230 along the thickness direction Z of the first flexible member 2. Figures 2 to 4 The dotted line portion is the ventilation hole 21 that passes through the first housing portion 220 and the second housing portion 230. The hollow chamber 20 is not connected to the plurality of ventilation holes 21.

[0053] In other words, the plurality of air holes 21 are arranged at intervals, and the connection between the air holes 21 is hollow, thereby forming a hollow chamber 20. The hollow chamber 20 includes a plurality of flow channels that are interconnected and crisscrossed.

[0054] For example, in a flat state (ie, not installed on a human fracture site), the first flexible member 2 is sheet-shaped. After being installed on a human fracture site, the first flexible member 2 forms a fixed space with a U-shaped or circular cross-section.

[0055] Figure 1 Shown is a fixing brace 1 for installation from the wrist to the palm of a human body. Figure 5 Shown is Figure 1 The first flexible member 2 corresponding to the fixing brace 1 is designed according to the shape of the human body from the wrist to the palm. Figure 5As shown, the first flexible member 2 includes a first edge 201, a second edge 202, a third edge 203, a fourth edge 204, a fifth edge 205, a sixth edge 206, a seventh edge 207, an eighth edge 208, a ninth edge 209, a tenth edge 210, an eleventh edge 211, a twelfth edge 212, a thirteenth edge 213 and a fourteenth edge 214 connected end to end in sequence; wherein the first edge 201 is perpendicular to the second edge 202 and the fourteenth edge 214 respectively; the second edge 202 and the third edge 203 are arranged at an obtuse angle ; The fourth edge 204 is perpendicular to the third edge 203 and the fifth edge 205 respectively; the fifth edge 205 is parallel to the seventh edge 207; the sixth edge 206 is arc-shaped; the seventh edge 207 and the eighth edge 208 are set at an acute angle; the eighth edge 208 and the ninth edge 209 are set at an acute angle; the ninth edge 209 and the eleventh edge 211 are parallel; the tenth edge 210 is arc-shaped; the twelfth edge 212 is perpendicular to the eleventh edge 211 and the thirteenth edge 213 respectively; the thirteenth edge 213 and the fourteenth edge 214 are set at an obtuse angle.

[0056] That is, the above-mentioned fourteen edges form an irregularly shaped first flexible member 2, wherein the rectangular area formed by the first edge 201, the second edge 202, and the fourteenth edge 214 corresponds to the position of the human wrist, and the trapezoidal area formed by the third edge 203, the fourth edge 204, the fifth edge 205, the sixth edge 206, the seventh edge 207, the eighth edge 208, the ninth edge 209, the tenth edge 210, the eleventh edge 211, the twelfth edge 212, and the thirteenth edge 213 corresponds to the position of the human palm. Those skilled in the art will understand that the fixation brace 1 of the present application can be installed on the limbs of the human body, such as the entire arm, calf, etc. The shape and size of the first flexible member 2 also need to be adjusted according to the corresponding fracture site of the human body.

[0057] Exemplarily, the curable material is a light-curable resin, that is, after the liquid light-curable resin is poured into the hollow chamber 20, it can be cured by light (such as ultraviolet light, natural sunlight), and the curing time is less than 10 minutes, which is convenient and quick.

[0058] In this embodiment, the curing strength of the light-curable resin after curing is 20N, and the hardness is not less than 80 Shore D.

[0059] It should be noted that before the first flexible member 2 is installed on the fracture site, the hollow chamber 20 is unfilled, allowing the first flexible member 2 to be bent to conform to the shape of the fracture site and conform to the skin. Once the first flexible member 2 is installed on the body, a curable material can be poured into the hollow chamber 20 and allowed to cure, thereby providing support for the fracture site.

[0060] In this embodiment, the first flexible member 2 is made of silicone rubber, but those skilled in the art will appreciate that in other embodiments, the first flexible member 2 may be made of other rubber materials, such as nitrile rubber, latex rubber, synthetic rubber, and the like.

[0061] like Figure 1 、 Figures 5 to 7 As shown, the above-mentioned second flexible member 3 is connected to the first flexible member 2; the second flexible member 3 includes a first connecting portion 31 and a second connecting portion 32 arranged opposite to each other, and the first connecting portion 31 and the second connecting portion 32 are connected to enclose the first flexible member 2 to form a fixed space, and the fixed space has a shape corresponding to the contour of the human fracture site to accommodate the human fracture site.

[0062] In this embodiment, the first flexible member 2 and the second flexible member 3 are integrally formed. However, those skilled in the art will appreciate that in other embodiments, the first flexible member 2 and the second flexible member 3 may also be connected by bonding, ultrasonic welding, or the like.

[0063] In this embodiment, the fixed space enclosed by the first flexible member 2 is U-shaped, and is used to wrap at least partially around the palm. Those skilled in the art will appreciate that in other embodiments, the fixed space may need to be shaped differently depending on the fracture site it corresponds to. For example, if the fracture site involves the entire arm, a cylindrical fixed space may be required.

[0064] For example, the first connection portion 31 and the second connection portion 32 of the second flexible member 3 are connected, and the first flexible member 2 which is originally in sheet form is curled into a shape that conforms to the contour of the fracture site of the human body.

[0065] In this embodiment, the second flexible member 3 is also made of silicone rubber. However, those skilled in the art will appreciate that in other embodiments, the second flexible member 3 can be made of other rubber materials, such as nitrile rubber, latex rubber, synthetic rubber, etc. The rubber-made first and second flexible members 2 and 3 are waterproof and washable, overcoming the problem of plaster casts that cannot be exposed to water.

[0066] refer to Figure 1 、 Figures 5 to 7Using the above technical solution, the fixation brace 1 is placed at the fracture site of the human body. The first connecting portion 31 and the second connecting portion 32 of the second flexible member 3 are then connected, so that the first flexible member 2 is rolled into a shape that conforms to the contour of the fracture site at that location. That is, the first flexible member 2 encloses a fixed space, which then wraps around the fracture site. A liquid curable material is then poured into the hollow chamber 20 and cured, causing the first flexible member 2 to harden as a whole, thereby providing support for the fracture site. The ventilation holes 21 provided on the first flexible member 2 provide ventilation for the skin at the fracture site.

[0067] In summary, this embodiment utilizes a first flexible member 2 and a second flexible member 3 made of flexible material, and infuses the hollow chamber 20 of the first flexible member 2 with a curable material to provide support for a fractured bone. Compared to plaster, this flexible material is lighter, more flexible, and more conformable to the skin. Furthermore, the skin at the fractured site is exposed to the outside air through the ventilation holes 21 provided in the first flexible member 2, thus preventing skin problems.

[0068] It should be noted that Figure 8 A schematic diagram showing a splint-type forearm fixation brace installed on a human body is shown; Figure 9 A schematic diagram showing the installation of a forearm fixation brace on a human body is shown.

[0069] like Figure 5 As shown, in some possible embodiments, the first flexible member 2 is provided with an injection hole 22, which is in communication with the hollow chamber 20 and is used to inject the curable material into the hollow chamber 20. For example, the first flexible member 2 is provided with two injection holes 22, which are located at both ends of the first flexible member 2.

[0070] In this embodiment, when pouring the curable material into the hollow chamber 20, one of the injection holes 22 is closed, and the curable material is poured through the other injection hole 22. However, those skilled in the art will appreciate that in other embodiments, the curable material may be poured through both injection holes 22 simultaneously to improve the pouring efficiency.

[0071] In some possible embodiments, the fixation brace 1 further includes a cover (not shown in the figure), which is used to seal the injection hole 22. That is, after the injection is completed, the injection hole 22 can be sealed by the cover to prevent the liquid curable material in the hollow chamber 20 from flowing out.

[0072] In some possible implementations, such as Figure 1 and Figure 6 As shown, in this embodiment, the second flexible member 3 is also in a sheet shape when laid flat, and its shape is substantially the same as that of the first flexible member 2 . However, the cross-sectional area of ​​the second flexible member 3 is larger than that of the first flexible member 2 .

[0073] Specifically, in this embodiment, the second flexible member 3 includes a first portion 33 and a second portion 30 that are connected. The first portion 33 covers the lower surface of the first flexible member 2 and overlaps and connects to the first flexible member 2. In other words, the first portion 33 of the second flexible member 3 and the first flexible member 2 have the same shape and size. The second portion 30 of the second flexible member 3 is located on both sides of the first flexible member 2 and includes a first connecting portion 31 and a second connecting portion 32.

[0074] Furthermore, the first portion 33 of the second flexible member 3 includes a plurality of communication holes 34. The plurality of communication holes 34 correspond to and communicate with the plurality of ventilation holes 21 in a one-to-one manner. For example, the communication holes 34 on the second flexible member 3 communicate with the ventilation holes 21 on the first flexible member 2 to prevent the second flexible member 3 from overlapping with the first flexible member 2, thereby preventing the ventilation holes 21 on the first flexible member 2 from being blocked by the second flexible member 3. This ensures that the skin at the fracture site can breathe through the ventilation holes 21.

[0075] In other embodiments, the first portion 33 of the second flexible member 3 may not completely cover the lower surface of the first flexible member 2, that is, the area of ​​the first portion 33 is relatively small, and it is only provided on the lower surface of the first flexible member 2 and close to the two sides, and is overlapped and bonded with the first flexible member 2. In this case, there is no obstruction of the air vent 21 by the second flexible member 3, so there is no need to provide a connecting hole 34 in the second portion 33, thereby further reducing the weight of the fixation brace 1 while simplifying the process and reducing the amount of material used.

[0076] In some possible implementations, such as Figure 1 and Figure 8 As shown, a connecting member 4 is further included, and the connecting member 4 connects the first connecting portion 31 and the second connecting portion 32 .

[0077] like Figure 1 and Figure 8 As shown, in this embodiment, the connecting member 4 is a Velcro 40. The first connecting portion 31 of the second flexible member 3 is provided with a first connecting hole 35, and the second connecting portion 32 is provided with a second connecting hole 36. The Velcro 40 passes through the first connecting hole 35 and the second connecting hole 36 to connect the first connecting portion 31 and the second connecting portion 32, so that the first flexible member 2 is rolled into a shape that matches the fracture site of the human body, such as a U shape.

[0078] Exemplarily, the first connection hole 35 and the second connection hole 36 are both rectangular. In this embodiment, three first connection holes 35 and three second connection holes 36 are provided, and the three first connection holes 35 and the three second connection holes 36 are distributed in a trumpet shape.

[0079] like Figure 9As shown, in other embodiments, the connecting member 4 is a zipper 41 , and the chain elements on both sides thereof are respectively arranged on the first connecting portion 31 and the second connecting portion 32 .

[0080] Those skilled in the art will appreciate that, in other embodiments, the connector 4 may also be a tie, an elastic band, a buckle, etc., or a combination of any of the above connectors.

[0081] The form of the connecting member 4 makes the fixation brace 1 of the present application easy to wear and remove.

[0082] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above description is provided to further illustrate the present invention in conjunction with specific embodiments, and that the present invention should not be construed as being limited to these descriptions. Those skilled in the art may make various changes in form and detail, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
