[0036] See Figures 1 to 4 .

[0037] This utility model relates to a finger-separating finger fixing device, comprising:

[0038] Support base 100, used to support the hand and install finger fixing mechanism 200;

[0039] Several finger fixing mechanisms 200 are installed on the support base 100, including a clamping member 210 for clamping the finger, a pressing member 220 for pressing the finger, and an adjusting member 230 for moving the pressing member 220 closer to or away from the finger.

[0040] In this invention, the support base 100 is used to support the hand and install the finger fixing mechanism 200, so as to simultaneously restrict and fix each finger for subsequent hand rehabilitation. Each finger fixing mechanism 200 can be used to fix one finger. In use, the adjusting member 230 drives the pressing member 220 as far away from the support base 100 as possible. Then, the finger is inserted into the clamping member 210. The clamping member 210 initially restricts the finger to a certain space. Then, the adjusting member 230 drives the pressing member 220 to move towards the finger, so that it fits the finger and fixes it. Finally, the finger of the hand is fixed separately on the fixing device of this invention.

[0041] This utility model has a simple overall structure, is easy to operate, provides good finger fixation and high comfort, and is convenient for finger rehabilitation work in various occasions. It can be operated with one hand and worn independently. The pressing part can be positioned in different positions through the adjustment part, so it can be adjusted according to different users and / or different hand shapes and rehabilitation requirements. The adjustment is also convenient and can adapt to the needs of different people and different rehabilitation environments, making it widely applicable.

[0042] See Figure 1 and Figure 2 In one embodiment, the finger fixing mechanism 200 is positionally adjustable on the support base 100. This design allows the finger fixing mechanism 200 to be adjusted in position on the support base 100 as needed, enabling finger fixation at different positions on the support base, thus facilitating finger fixation for different individuals and expanding its applicability.

[0043] See Figure 1 and Figure 2In one embodiment, the finger fixation mechanism 200 is mounted on the support base 100 in an adjustable position using the following structure: the support base 100 includes a palm portion 110 and a plurality of finger portions 120, and each finger fixation mechanism 200 is slidably fitted onto each finger portion via a sleeve interface 211 provided on the corresponding clamping member 210. This design adapts the shape of the support base 100 to the shape of the hand, allowing the palm portion to support the patient's hand, while the finger fixation mechanism 200, slidably fitted onto the finger portion 120 of the support base via the sleeve interface 211, allows for more precise and convenient position adjustment, enabling the selection of an appropriate preset position for hand fixation according to the patient's requirements.

[0044] In use, the finger fixing mechanism 200 can be adjusted to a suitable position on the finger 120, such as the end of the finger. The cooperation and constraint between the clamping member 210 and the pressing member 220 fixes the finger on the support base 100.

[0045] See Figures 2 to 4 In one embodiment, the pressing member 220 is movably disposed within the clamping member 210, and the adjusting member 230 is disposed on the clamping member 210 and connected to the pressing member 220. The adjusting member 230 can drive the pressing member 220 to reciprocate within the clamping member 210. This design is simple and reasonable in structure and easy to operate.

[0046] See Figures 2 to 4 In one embodiment, the clamping member 210 has a frame-shaped structure, with its bottom end mounted on the support base 100 and the adjusting member 230 disposed at its top end. This design creates an internal accommodating space within the clamping member 210, allowing fingers to be placed within this space and secured by the pressing member 220.

[0047] The bottom end of the clamp 210 has a sleeve interface 211. The width of the sleeve interface 211 is adapted to the finger part 120. The sleeve interface 211 engages and fixes with the finger part 120 to maintain a small plane difference with it, so that the hand can fit better with the support base 100 and the finger fixing mechanism 200 after it is fixed to the support base 100.

[0048] See Figures 2 to 4 In one embodiment, the adjusting member 230 includes a screw 231 that is threadedly engaged with a screw hole 212 formed on the clamping member 210, and the inner end of the screw 231 is hinged to the pressing member 220. This design is simple in structure and easy to adjust. The position of the pressing member 220 can be adjusted by rotating the screw 231. Since the screw 231 is hinged to the pressing member 220, the pressing member 220 does not need to rotate with the screw 231, thus achieving stable pressing of the finger.

[0049] See Figure 3 , in a specific implementation, the pressing member 220 is hinged to the inner end of the screw rod 231 through a ball hinge 221. With this design, the structure is simple, and the hinge has a higher degree of freedom and the structure is more stable.

[0050] See Figure 3 , in a specific implementation, the outer end of the screw rod 231 is connected with a knob 232. With this design, the screw rod 231 can be rotated through the knob 232, and the operation is more convenient.

[0051] See Figure 6 , in another embodiment, the adjusting member 230 is a driving member 233 that can expand and contract by inflating and deflating, such as a bellows-shaped bladder. With this structure, the pressing member 220 can be reciprocally moved within the clamping member 210 by inflating and deflating, and the operation is more convenient. In a specific implementation, the top of the driving member 233 is connected to the clamping member 210, and the bottom is connected to the pressing member 220. The driving member 233 is connected to an inflating and deflating device, such as an air pump.

[0052] See Figures 2 to 4 , in an embodiment, a slide rail 213 is provided on the clamping member 210, the slide rail 213 is arranged along the expansion and contraction direction of the adjusting member 230, and the pressing member 220 is slidably connected to the clamping member 210 through the slide rail 213. With this design, the pressing member 220 and the adjusting member 230 form a lead screw-nut mechanism, and the rotational movement of the adjusting member 230 can be converted into the linear sliding of the pressing member 220, and the pressing member will not rub the finger skin.

[0053] See Figures 2 to 4 , in an embodiment, the slide rail 213 is a groove structure, and the slide rail 213 penetrates through the bottom surface of the clamping member 210. With this design, it is convenient for the formation of the slide rail 213, and it is also convenient for the pressing member 220 to enter the slide rail while being inserted into the clamping member 210, which is convenient for meeting the overall manufacturing and installation requirements.

[0054] See Figures 2 to 4 , in an embodiment, the pressing member 220 has a "door" - shaped structure, and the bottom ends of the pressing member 220 and the clamping member 210 enclose a space for accommodating a finger. With this design, the pressing member 220 has a better limiting effect on the finger.

[0055] Or the pressing member 220 having a "work" - shaped structure can also achieve the function of pressing and limiting.

[0056] See Figures 2 to 4 , more preferably, slide rails 213 are respectively provided on the inner walls of the left and right sides of the clamping member 210, and the left and right sides of the pressing member 220 are respectively slidably installed in the corresponding slide rails 213. With this design, the structure is more stable.

[0057] In one embodiment, the inner circumferential surface of the pressing member 220 and the inner bottom surface of the clamping member 210 are both provided with sponge pads to reduce the squeezing sensation on the fingers when fixing them, thereby protecting the fingers and improving the comfort of fixing them.

[0058] See Figure 5 In one embodiment, the support base 100 is a malleable support plate. The support plate can be bent arbitrarily under external force to better adapt to the patient's hand shape. It can also deform according to the patient's hand movements during finger training, reducing restriction on the hand and improving wearing comfort. The support plate can adjust the bending angle according to the degree of finger spasm to adapt to finger fixation in different states and finger rehabilitation training in different states. The bending angle of the fingers can be changed according to the user's requirements to achieve hand rehabilitation training at different angles, improving comfort. The overall structure is simple, easy to carry, suitable for various groups of people, and can be used in various situations. The bending angle can be adjusted according to the degree of finger spasm to adapt to finger rehabilitation training in different situations, especially conforming to the different angles of the thumb and other four fingers. The palm and / or wrist portion of the support base can also be a tabletop structure, suitable for public training environments, improving efficiency.

[0059] In other embodiments, the support base 100 may also be other support platforms capable of supporting the hand and mounting the clamp 210.

[0060] In summary, this invention's finger-separating fixing device utilizes the cooperation of the pressing member 220 and the clamping member 210 to fix the fingers, and combines this with the adjusting member 230 to precisely fix the fingers, enabling wide application for different individuals and in different situations. Simultaneously, a sponge pad is placed in the area where the finger-separating device directly contacts the fingers, improving comfort while fixing the fingers. The adjustment method is simple and convenient; simply rotating the knob 232 on the adjusting member 230 allows for tightening and loosening of the pressing member 220 relative to the fingers. The support plate adapts to the shape of the hand and can bend with the hand, facilitating hand movement and improving comfort. The overall structure is simple, portable, and can be operated with one hand for independent donning. It is suitable for various groups of people and can be used in various situations, demonstrating strong practicality and wide applicability.
