The functional position refers to the position where the limb can exert the maximum function. Therefore, after the limb is injured, it generally needs to be fixed in the functional position.

The traditional hand fixation device only fixes the metacarpophalangeal joint and the proximal and distal interphalangeal joints in the functional position, while ignoring the fixation of the wrist joint. In the actual clinical process, the antispasmodic treatment of the wrist is also very important for hemiplegic patients. .

As shown in FIG. 1 to FIG. 3 , in this embodiment, a fixing device for keeping the hand and the wrist in the functional position is used to keep the fingers, the palm, and the wrist in the functional position. The fixing device includes: :

Support seat 1;

The wrapping sheet 2, which is arranged on the support base 1, is used to wrap the palm and the wrist;

Six partition protrusions 3 are respectively disposed on the support base 1, two adjacent partition protrusions 3 are clamped to form an accommodating channel 5 for accommodating the fingers, and the partition protrusion 3 is provided with a protrusion toward the accommodating channel 5. The wrapping portion 4 that is raised and used to wrap the fingers;

The support base 1, the wrapping sheet 2, and the six separating protrusions 3 are surrounded by an accommodating cavity 6 for accommodating fingers, palms, and wrists; the wrapping sheet 2 and the separating protrusions 3 are all made of elastic materials; The wrist part and the palm part can stretch the wrapping sheet 2 to accommodate the accommodating cavity 6 ; the fingers can stretch the wrapping part 4 to accommodate the accommodating channel 5 . Specifically, when in use, fingers, palms, and wrists are respectively pressed downwards from the top of the fixing device, and the wrapping sheet 2 and the separating protrusions 3 are spread apart, so that the fingers enter the accommodating channel 5, and the palms and wrists enter the accommodating cavity 6, and is wrapped, so that both the hand and the wrist remain in the functional position. The fixing device has a simple structure and greatly reduces the use cost. By increasing the wrapping area of the fixing device, the pressing force on the hand and the wrist caused by the fixing device during use is reduced, and the comfort during use is greatly improved, which has good practical significance.

Specifically, the one-piece molding can make the gripping force of the hand act on the fixing device well, and the fixing device can be reset after the hand is released, and the hand can be re-fixed in the functional position state. The elastic material is a prior art material such as rubber and silica gel, which will not be repeated here.

As shown in FIGS. 1 to 3 , in this embodiment, the fixing device further includes a detachable wrapping support base 1 , wrapping sheets 2 , and a sheath for separating the protrusions 3 . Specifically, the fixing device will inevitably get dirty during use, and it is wrapped with a detachable sheath. After the fixing device is soiled, it is only necessary to replace, clean and disinfect the sheath instead of replacing the entire sheath. It saves the user's cost and has good practical significance.

As shown in FIG. 1 to FIG. 3 , in this embodiment, the fixing device includes a glove that can be adhered to the sheath to prevent the hand and the wrist from falling off the fixing device. Specifically, a hook surface or a mushroom hasp of the Velcro is arranged on the sheath at the position at the bottom of the accommodating cavity 6 and the accommodating channel 5, and a fleece surface or a mushroom hasp of the Velcro is arranged on the glove, so that the When the fingers, palms, and wrists open the wrapping portion 4 and wrapping sheet 2 respectively, no resistance is increased, and when the fingers, palms, and wrists are accommodated in the accommodating channel 5 and the accommodating cavity 6 , can play a very good role in fixing, has very good practical significance.

As shown in FIGS. 1 to 3 , in this embodiment, the sheath is equipped with a neuromuscular electrical stimulation device for inducing hand muscle action. Specifically, the neuromuscular electrical stimulation device is arranged on the sheath, which can be used for inducing muscle movements of the forearm and hand of the patient with retardation type paralysis. For strength training of disused muscles to maintain muscle mass, maintain and increase joint range of motion, promote voluntary muscle control, and reduce spasticity. The neuromuscular electrical stimulation device belongs to the existing conventional technology and will not be repeated here.

As shown in FIG. 1 to FIG. 3 , in this embodiment, the support base 1 , the wrapping sheet 2 , and the partition protrusion 3 are all provided with a plurality of ventilation holes. Specifically, adding ventilation holes can keep fingers, palms, and wrists in a functional position in a dry state, which greatly improves the comfort of the fixing device during use, and has great practical significance.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes.
