Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a finger rehabilitation device. Background Technology

[0002] A finger rehabilitation device is a rehabilitative device used to aid in the recovery of hand and finger function, typically used during rehabilitation from finger injuries, post-surgery, or hand conditions such as arthritis and tendon injuries. Through specific training methods and device design, it helps enhance finger strength, flexibility, and range of motion. Finger rehabilitation devices play a crucial role in hand function recovery; with proper use, they can significantly improve finger mobility and quality of life. A similar finger rehabilitation device is disclosed in utility model patent publication number CN219763877U.

[0003] The aforementioned finger rehabilitation devices connect to the hand via a glove. To facilitate the generation of resistance to the fingers, finger sleeves are typically placed at the fingertips of the glove for the user to insert their fingers, thus securing the glove's fingertips to the user's fingers. However, these finger sleeves are usually made of flexible fabric, which not only causes a loss of force during hand resistance training, affecting the effectiveness of finger rehabilitation, but also leads to loosening after repeated use, affecting the tightness of the connection between the glove and the fingers. Therefore, there is still room for improvement. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a finger rehabilitation device. A rigid finger sleeve securely connects the fingertip of the glove to the user's hand, preventing force loss during resistance training and effectively preventing the finger sleeve from loosening, thereby improving the training effect.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A finger rehabilitation device includes a glove with a rigid finger sleeve at the fingertip. The rigid finger sleeve has a slot for finger insertion. A replaceable flexible patch is provided on the side wall of the slot away from the fingertip. At least one connecting post is provided on the side of the replaceable flexible patch away from the fingertip. A connecting hole is provided on the side wall of the slot for the connecting post to pass through. An elastic positioning ring is provided around the part of the connecting post that extends beyond the rigid finger sleeve to prevent the connecting post from disengaging from the connecting hole.

[0007] The above solution uses rigid finger cots instead of flexible ones to securely connect the glove's fingertips to the user's fingers. This not only prevents loss of force during resistance training, improving training efficiency, but also effectively prevents the finger cots from loosening, maintaining a good fit between the cots and fingers. Replaceable flexible patches within the slots enhance finger comfort and increase fingertip friction, further strengthening the connection between the fingers and the finger cots. The interplay between the connecting post, connecting hole, and elastic positioning ring allows for a detachable connection between the replaceable flexible patches and the slot sidewalls, enabling users to easily replace patches of different thicknesses to suit their finger width, further improving the fit between the fingers and the rigid finger cots.

[0008] Preferably, the rigid finger sleeve includes a fixed part fixed to the fingertip and a movable part covering the fixed part away from the fingertip. The movable part is pivotally connected to the fixed part near the slot opening on the side near the slot opening, and the plane of rotation is perpendicular to the plane where the fingertip is located. A locking mechanism is provided between the movable part and the fixed part to keep the movable part in a closed state.

[0009] The above design allows the movable part to fold outwards, fully exposing the inner side of the slot, thus facilitating the replacement of the flexible patch and cleaning of the slot, further improving operational convenience. The locking mechanism keeps the movable part closed, allowing the rigid finger sleeve to be used normally.

[0010] Preferably, the fixed part has pivot seats on both sides near the slot opening, and the movable part has pivot shafts on both sides near the slot opening, which are respectively rotatably inserted into the two pivot seats.

[0011] By adopting the above solution, the cooperation between the pivot shaft and the pivot seat can achieve stable rotation of the moving part, while improving the smoothness of the rotation.

[0012] Preferably, the movable part has an arc-shaped surface on the side near the fixed part and at the slot opening.

[0013] Using the above solution, the arc surface can flatten the corners of the moving part, thereby preventing the moving part from being obstructed when flipping.

[0014] Preferably, the locking mechanism includes a first fixed seat disposed on the side of the movable part away from the slot opening and a second fixed seat disposed on the side of the fixed part away from the slot opening. When the movable part is closed on the fixed part, the first fixed seat is engaged with the second fixed seat, and a locking component is provided between the first fixed seat and the second fixed seat to prevent the first fixed seat from disengaging from the second fixed seat.

[0015] Preferably, the locking assembly includes a locking hole on the first fixed seat and a threaded hole on the second fixed seat, wherein a screw threaded into the locking hole and screwed into the threaded hole is provided to prevent the first fixed seat from disengaging from the second fixed seat.

[0016] By adopting the above solution, the moving part can be stably connected to the fixed part, thereby improving the locking performance of the locking mechanism.

[0017] As a preferred alternative, a silicone pad can be used instead of a flexible patch.

[0018] Using the above solution, silicone material has the advantages of good feel and low allergenicity, which can effectively improve the user experience of replaceable flexible patches.

[0019] Preferably, the glove has an air tube along the length of each finger on the back side of the hand, and each air tube has several retractable corrugated segments distributed along its own length. The port of the air tube near the fingertip is sealed.

[0020] Using the above method, the expansion and contraction of the trachea can provide resistance to the finger area of ​​the glove, thereby helping the user to perform rehabilitation training.

[0021] Preferably, the back of the glove is provided with several buckles for securing the air tube, with the notches of the buckles facing to the right.

[0022] The above solution allows the trachea to be stably installed on the back of the glove, while ensuring the ease of installation and removal of the trachea.

[0023] This invention, employing the above technical solutions, achieves significant technical advantages: by replacing flexible finger sleeves with rigid finger sleeves to securely connect the glove's fingertips to the user's fingers, it not only prevents force loss during hand resistance training, thus improving training efficiency, but also effectively prevents the finger sleeves from loosening, maintaining a secure fit between the finger sleeves and the fingers. The replaceable flexible patch within the slot enhances finger comfort and increases fingertip friction, further strengthening the connection between the finger and the finger sleeve. The cooperation between the connecting post, connecting hole, and elastic positioning ring enables a detachable connection between the replaceable flexible patch and the slot sidewall, allowing users to easily replace flexible patches of different thicknesses according to their finger width, further improving the fit between the finger and the rigid finger sleeve.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0035] like Figure 1 and Figure 2As shown, this embodiment discloses a finger rehabilitation device, including a glove 1. A rigid finger sleeve 3 is fixedly mounted on the fingertip portion 2 and the palm side of the glove 1. The rigid finger sleeve 3 is preferably made of plastic, making it lightweight and sturdy. An air tube 20 is provided on the back side of the glove 1 along the length of each finger. Each air tube 20 has several stretchable corrugated segments 21 distributed along its length. The port of the air tube 20 near the fingertip portion 2 is sealed. Several buckles 30 for engaging the air tubes 20 are provided on the back side of the glove 1. Each set of buckles 30 is arranged along the finger portion of the glove 1, so that the resistance generated by the expansion and contraction of the corrugated segments 21 can be evenly distributed on the user's fingers. The notches 31 of the buckles 30 face to the right, thereby improving the ease of assembling and disassembling the air tubes 20. All the ends of the air tubes 20 away from the fingertip 2 are connected to a manifold 22. The manifold 22 is connected to an external connector 24 through an air guide tube 23. The external connector 24 is provided with an air inlet connector 26 for connecting to an external air source 25.

[0036] In this embodiment, when the external air source 25 blows air into the air pipe 20 through the air guide pipe 23 and the confluence device 22 in sequence, the corrugated section 21 on the air pipe 20 can expand along its own length direction to drive the corresponding air pipe 20 to straighten, thereby forming resistance against the opening of the fingers, so that the user can perform resistance training to straighten the fingers.

[0037] Conversely, when the external air source 25 operates in the reverse direction to draw air into the air tube 20 through the air guide tube 23 and the confluence device 22, the corrugated section 21 on the air tube 20 can contract along its own length direction to drive the corresponding air tube 20 to shorten, thereby forming resistance against the inward bending of the fingers, allowing the user to perform resistance training for finger bending.

[0038] To enable independent operation of each tracheal tube 20, a regulating valve 27 is installed on each tracheal tube 20 to control its operation. When a tracheal tube 20 needs to be operational, simply open the regulating valve 27 on that tracheal tube 20 to allow it to be open, thus enabling the external air source 25 to supply or evacuate air from that tracheal tube 20. Conversely, when a tracheal tube 20 needs to be stopped, simply close the regulating valve 27 on that tracheal tube 20 to cut off its operation, thus preventing the external air source 25 from supplying or evacuating air from that tracheal tube 20.

[0039] like Figure 3 As shown, in order to achieve the hand heating function, a heating layer 28 is sewn inside the glove 1, and heating wires (not shown) are distributed on the heating layer 28. An electrical connector 29 is also provided on the external connector 24 to connect to the heating wires and supply power to the heating wires via an external power source (not shown).

[0040] like Figures 4 to 7As shown, to improve the comfort and fit of the finger within the rigid finger sleeve 3, the rigid finger sleeve 3 has a slot 4 for finger insertion. A replaceable flexible patch 5 is provided on the side wall of the slot 4 away from the fingertip portion 2. At least one connecting post 6 is provided on the side of the replaceable flexible patch 5 away from the fingertip portion 2. A connecting hole 7 is provided on the side wall of the slot 4 for the connecting post 6 to pass through. A retaining ring 8 is provided around the portion of the connecting post 6 extending beyond the rigid finger sleeve 3 to prevent the connecting post 6 from disengaging from the connecting hole 7. In this embodiment, the replaceable flexible patch 5 is a silicone pad, and the connecting post 6 and the retaining ring 8 are also made of silicone and are integrally formed with the replaceable flexible patch 5.

[0041] like Figure 8 and Figure 9 As shown, to facilitate the replacement of the flexible patch and the cleaning of the slot 4, the rigid finger sleeve 3 includes a fixing part 9 that is glued to the fingertip part 2 and a movable part 10 that covers the side of the fixing part 9 away from the fingertip part 2. The movable part 10 is pivotally connected to the side of the fixing part 9 near the opening of the slot 4, and the plane of rotation is perpendicular to the plane of the fingertip part 2. A locking mechanism 11 is provided between the movable part 10 and the fixing part 9 to keep the movable part 10 in a closed state. Specifically, pivot seats 12 are provided on both sides of the fixing part 9 near the opening of the slot 4, and pivot shafts 13 are provided on both sides of the movable part 10 near the opening of the slot 4, which are respectively rotatably inserted into the two pivot seats 12. An arc surface 14 is provided on the side of the movable part 10 near the fixing part 9 and near the opening of the slot 4 to prevent the movable part 10 from being obstructed when it is flipped.

[0042] like Figure 4 and Figure 8 As shown, to ensure the locking capability of the locking mechanism 11, the locking mechanism 11 includes a first fixed seat 15 disposed on the side of the movable part 10 away from the opening of the slot 4 and a second fixed seat 16 disposed on the side of the fixed part 9 away from the opening of the slot 4. When the movable part 10 is closed onto the fixed part 9, the first fixed seat 15 abuts against the second fixed seat 16. A locking component is provided between the first fixed seat 15 and the second fixed seat 16 to prevent the first fixed seat 15 from disengaging from the second fixed seat 16. Specifically, the locking component includes a locking hole 17 opened on the first fixed seat 15 and a threaded hole 18 opened on the second fixed seat 16. A screw 19, threaded into the threaded hole 18, passes through the locking hole 17 to prevent the first fixed seat 15 from disengaging from the second fixed seat 16.

[0043] The specific usage process is as follows:

[0044] When using the finger rehabilitation device, first put on the glove 1 and secure it in place. Then, insert each of the five fingers into the corresponding slot 4 of the rigid finger sleeve 3 to connect the user's hand to the glove 1. During finger rehabilitation training, the rigid finger sleeve 3 provides stable support to the fingers, enhancing the effectiveness of the training. Simultaneously, the rigid finger sleeve 3 effectively prevents loosening, thus maintaining a tight connection between the fingers and the finger sleeves.

[0045] To improve the fit between the finger and the rigid finger sleeve 3, replaceable flexible patches 5 of different thicknesses can be installed on the side wall of the slot 4 of the rigid finger sleeve 3. During installation, first remove the screws 19 on the corresponding rigid finger sleeve 3 to release the lock between the first fixing seat 15 and the second fixing seat 16. Then, using the pivot shaft 13 as the center, open the movable part 10 on the rigid finger sleeve 3 outwards to expose the interior of the slot 4. At this point, the original replaceable flexible patch 5 can be removed from the inside of the movable part 10. During disassembly, the elastic positioning ring 8 can contract under the pressure of the connecting hole 7, allowing the connecting post 6 to smoothly disengage from the connecting hole 7. Once all the connecting posts 6 have disengaged from the connecting hole 7, the entire replaceable flexible patch 5 can be removed from the movable part 10.

[0046] After removing the replaceable flexible patch 5, reinstall a replaceable flexible patch 5 of appropriate thickness inside the movable part 10. During installation, insert the connecting posts 6 on the back of the replaceable flexible patch 5 into the corresponding connecting holes 7 in sequence. During insertion, the elastic positioning ring 8 at the end of the connecting post 6 can contract under the compression of the connecting hole 7, allowing the connecting post 6 to smoothly enter the connecting hole 7. After the connecting post 6 has passed through the entire connecting hole 7, the elastic positioning ring 8 returns to its original position, thus completing the axial positioning of the connecting post 6. Once all the connecting posts 6 are aligned with the connecting holes 7, the installation of the replaceable flexible patch 5 is complete.

[0047] After installing the flexible patch, close the movable part 10 again so that the first fixed seat 15 mates with the second fixed seat 16. At this time, insert the screw 19 into the locking hole 17 and screw it into the threaded hole 18 to complete the fixed connection between the first fixed seat 15 and the second fixed seat 16, thereby locking the movable part 10 and the fixed part 9, and enabling the corresponding hard finger sleeve 3 to be used normally.
