[0002] After treatment of wrist fracture or wrist sprain, the wrist usually needs to be fixed to avoid bone dislocation or bending. The traditional fixation method is usually to use plaster and gauze for fixation, and then remove it after the bone recovers. The process of applying and removing plaster is cumbersome, time-consuming and labor-intensive, and the plaster has poor air permeability and is relatively uncomfortable to use.

[0003] Traditional wrist guards are usually used for sports protection, mainly to prevent wrist sprains during exercise, and do not have the function of fixing bones.

[0004] In view of this, the applicant conducted in-depth research on the structure of the wrist guard and the fixing structure of the wrist, which led to the present case. Utility Model Content

[0005] The utility model aims to provide a medical wrist guard which is time-saving and labor-saving to assemble and disassemble and has relatively good comfort when used.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A medical wrist guard comprises a front support piece, a first pull tab connected to one side of the front support piece, and a second pull tab connected to the other side of the front support piece, an elastic component is arranged between the first pull tab and the second pull tab, a front bag piece is sewn to the front support piece, a front pocket is formed between the front bag piece and the front support piece, a supporting rigid plate is inserted in the front pocket, the first pull tab and the second pull tab are both connected to side bag pieces, a side pocket is formed between each side bag piece and the corresponding pull tab, an insulating bag is arranged in each side pocket, the insulating bag is filled with electrorheological fluid, the electrorheological fluid is connected to a controller through a wire, and the controller is electrically connected to a power supply.

[0008] As an improvement of the present invention, the controller is fixedly connected to the first pull tab or the second pull tab, and the controller has a wireless communication module and / or a wired communication interface.

[0009] As an improvement of the present invention, the elastic assembly includes at least two first threading buckles fixedly connected to the first pull tab, at least two second threading buckles fixedly connected to the second pull tab, a tension adjuster fixedly connected to the first pull tab or the second pull tab, and a pull rope alternately wound between the first threading buckle and the second threading buckle and connected to the tension adjuster.

[0010] As an improvement of the present invention, a thumb hole is formed between the first pull tab or the second pull tab and the front supporting piece.

[0011] As an improvement of the present invention, a telescopic piece is fixedly connected between the first pull tab and the second pull tab.

[0012] As an improvement of the present invention, the front supporting piece, the first pull tab and the second pull tab are all made of warp-knitted three-layer mesh fabrics, and the edges of the front supporting piece, the first pull tab and the second pull tab are all provided with edging.

Preferably, the front support piece 10, the first pull tab 20 and the second pull tab 30 are all warp-knitted three-layer mesh fabrics with good air permeability, and the edges of the front support piece 10, the first pull tab 20 and the second pull tab 30 are all provided with edging. Of course, edging is not required at the position where the front support piece 10 is connected to the first pull tab 20 and the second pull tab 30.

[0031] When the medical wrist guard provided in this embodiment is unfolded into a plane, the first pull tab 20, the front support tab 10 and the second pull tab 30 are arranged in sequence. When in use, the front support tab 10 is located in the palm surface direction of the palm, and the first pull tab 20 and the second pull tab 30 cover the wrist joint from both sides. For ease of description, in this embodiment, the side of the medical wrist guard facing the wrist joint when in use is the inner side, and the corresponding other side is the outer side.

[0032] An elastic component 40 is arranged between the first pull tab 20 and the second pull tab 30. The elastic component 40 can be a conventional elastic component, such as Velcro or elastic band used in traditional wrist guards. Preferably, in order to achieve quick elasticity, in this embodiment, the elastic component 40 includes at least two first threading buckles 41 fixedly connected to the first pull tab 20, at least two second threading buckles 42 fixedly connected to the second pull tab 30, an elastic regulator 43 fixedly connected to the first pull tab 20 or the second pull tab 30, and a pull rope 44 alternately wound between the first threading buckle 41 and the second threading buckle 42 and connected to the elastic regulator 43, wherein each first threading buckle 41 and each second threading buckle 42 are arranged in a straight line and the arrangement of the two is parallel to each other, and the elastic regulator 43 has the same structure as the shoelace elastic regulator sold on the market, and its matching structure with the pull rope 44 is also the same as the matching structure of the shoelace elastic regulator and the shoelace, which will not be described in detail here.

[0033] A thumb hole 11 is formed between the first pull tab 20 or the second pull tab 30 and the front support sheet 10. When in use, the user's thumb is inserted into the thumb hole 11, which helps to improve the firmness of the medical wrist guard. Whether the thumb hole 11 is specifically arranged between the first pull tab 20 and the front support sheet 10 or between the second pull tab 30 and the front support sheet 10 depends on whether the injured wrist is the left hand or the right hand.

[0034] Preferably, a telescopic piece 50 is fixedly connected between the first pull tab 20 and the second pull tab 30, and the two ends between the first pull tab 20 or the second pull tab 30 and the front support sheet 10 are respectively connected one-to-one to the inner sides of the first pull tab 20 and the second pull tab 30, so that the front support sheet 10, the first pull tab 20, the second pull tab 30 and the telescopic piece 50 can form an annular structure together. When in use, the hand can be put on or extended out of the annular structure to achieve putting on and taking off. This can avoid the need to re-thread the pulling rope 44 every time use, thereby further improving the efficiency of putting on and taking off.

[0035] A front pocket piece 12 is sewn onto the front support piece 10, and a front pocket is formed between the front pocket piece 12 and the front support piece 10.

A support rigid plate 60 is inserted in the front pocket for fixing the wrist joint. The support rigid plate 60 has a concave arc for support corresponding to the rear part of the palm surface of the human body, which helps to reduce discomfort during use. In the later stage of rehabilitation, the support rigid plate 60 can be taken out from the front pocket for proper rehabilitation training. When in use, due to the pulling force of the first pull tab 20 and the second pull tab, the front support piece 10 and the front pocket piece 12 will be tightened, and then the support rigid plate 60 can be clamped in the front pocket.

[0036] The first pull tab 20 and the second pull tab 30 are both connected with a side pocket piece 21. The number of side pocket pieces 21 provided on each pull tab 20 can be more than two, and the specific setting position can be determined according to actual needs, such as being located on the side of the wrist joint or on the back of the hand when in use. A side pocket is formed between each side pocket piece 21 and the corresponding pull tab, and each side pocket is relatively closed, that is, the side pocket has no opening, or the opening of the side pocket can be sealed by a zipper or Velcro. An insulating bag is provided in each side pocket, the inner cavity of the insulating bag is sealed, and the insulating bag is filled with an electrorheological fluid, the electrorheological fluid is connected to a controller (not shown in the figure) through a wire, and the controller is electrically connected to a power supply (not shown in the figure), so that the controller can be used to connect or disconnect the connection between the power supply and the electrorheological fluid, and control the current, thereby changing the state of the electrorheological fluid, so that it solidifies into a solid with a predetermined rigidity when in use. The electrorheological fluid and the controller are both conventional components and can be purchased as a set on the market.

[0037] Preferably, the controller 22 is fixedly connected to the first pull tab 20 or the second pull tab 30, preferably between two adjacent first threading buckles 41 or two adjacent second threading holes 42, and preferably embedded between two layers of fabric of the corresponding pull tab to form a hidden design. The controller itself does not have any operating buttons, and it has a wireless communication module and or a wired communication interface, which can minimize the size of the controller 22 and reduce the weight of the medical wristband, and also avoid false triggering during use. When it is necessary to open or close or adjust the current, a mobile phone is used to communicate with the controller 22 by wire or wirelessly for operation. Of course, the relevant software needs to be pre-installed in the mobile phone, and the mobile phone and the relevant software are not part of the medical wristband provided in this embodiment, and need to be configured separately when used.
