Description

Technical Field

[0001] This invention relates to the field of hand rehabilitation equipment technology, specifically a human hand nerve therapy and rehabilitation training device. Background Technology

[0002] Nerve damage in the hand often leads to finger dysfunction, including limited finger movement and decreased dexterity. To restore normal finger function, devices such as pneumatic gloves are usually worn on the patient's hand. By changing the air pressure, the fingers or wrist can be moved to open, close, and extend, which reduces muscle atrophy, maintains the range of motion of the joints, and gradually restores finger dexterity.

[0003] Traditional rehabilitation equipment is usually limited to enabling basic opening and closing and grasping movements of the fingers and wrists, and has limited ability to provide effective hand massage and stimulation. This may not be enough to fully activate the nerve endings in the hand, thus affecting the speed and quality of the nervous system's recovery. In addition, such equipment often has difficulty in performing stretching, opening and closing, and bending movements of the fingers simultaneously, which limits the targeted nature and overall effectiveness of rehabilitation training. Summary of the Invention

Several air holes are provided on the upper surface of the elastic ball, and the air inside the elastic ball communicates with the outside through the air holes. A one-way valve is provided on one side of the lower end of the elastic ball, so that external air can only enter the interior of the elastic ball through the one-way valve.

[0017] The beneficial effects of this invention are:

[0018] 1. When in use, the invention controls the opening of the cover of each front and rear fixed chamber by simultaneously activating the lifting mechanism in the front and rear fixed chambers. The upper covers of every two adjacent fixed chambers come into contact, limiting the upper end of the finger. In conjunction with the air pump, the clamping airbag inflates to massage and stimulate both sides of the proximal and middle phalanges, while simultaneously clamping the proximal and middle phalanges of the patient.

[0019] 2. When in use, the present invention activates the bending component, causing the finger plate to flip upward or downward relative to the palm plate. Through the gripping of the fingers by the front and rear finger clamping components, the finger plate causes the middle phalanx to extend upward or bend downward relative to the proximal phalanx, thus activating the finger joint. At the same time, the bending component extends and retracts to control the finger plate away from the palm plate, stretching the finger joint, improving the flexibility of the finger joint, increasing its range of motion, and helping to maintain muscle strength and volume.

[0020] 3. When in use, the present invention drives the tensioning component to extend outward in the horizontal direction by setting the transmission component, controls the five fingers to complete the opening and closing tensioning action in the horizontal direction, and simultaneously starts the cylinder to drive the support and palm plate to move forward to stretch the wrist joint, and at the same time cooperates with the bending component to realize the synchronous bending and opening and closing tensioning action of the fingers.

[0021] 4. In use, this invention uses an elastic ball adhesively bonded to the edge of the palm hole. When the fingers are closed, the palm of the hand bulges, causing the anti-loosening band to move upward. At this time, a section of the anti-loosening band at the lower end of the palm plate tightens, pushing the elastic ball upward and making it fit against the palm, providing support and massage to the palm and improving hand comfort. At the same time, when the elastic ball is squeezed, the gas inside the elastic ball is blown out from the air hole, blowing air into the palm to dissipate heat and improve the patient's palm comfort.

The terms "first," "second," etc., used in this application are used to distinguish the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage," unless otherwise specified, include both direct and indirect connections (linkages). The foregoing and other technical contents, features, and effects of this invention are described below in conjunction with the accompanying drawings. Figures 1 to 10 As will be clearly shown in the detailed description of the embodiments, the structural contents mentioned in the following embodiments are all with reference to the accompanying drawings.

[0034] Example 1: This example provides a human hand nerve therapy and rehabilitation training device, such as... Figure 1-10As shown, the table includes a table body 1, which consists of a tabletop 102, table legs 103, and casters. A groove 4 is provided on the tabletop 102, and a support 5 is slidably mounted within the groove 4. A cylinder 7 is located at the rear end of the groove 4 to drive the support 5 to slide back and forth. A palm plate 6 is fixedly connected to the upper surface of the support 5. A rear arc-shaped groove 42 is provided at the front end of the palm plate 6, and a palm plate chamber 54 is formed in conjunction with the rear arc-shaped groove 42. A rear tensioning assembly is provided within the palm plate chamber 54, which slidably engages with the rear arc-shaped groove 42. A transmission assembly is engaged at the rear end of the rear tensioning assembly. Six rear finger clamping assemblies are fixedly connected to the upper end of the rear tensioning assembly. The front ends of the five rear finger clamping assemblies on the right side are all fixedly connected to corresponding bending assemblies. The other end of each bending assembly is hinged to a corresponding front finger clamping assembly. A front tensioning assembly is fixedly connected to the lower end face of the front finger clamping assembly. A finger plate connecting assembly is fixedly connected to the front of the palm plate 6, and a finger plate 11 is hinged to it through the finger plate connecting assembly. The front end of the finger plate 11 has a front arc-shaped groove 56, and a finger plate cavity 57 is formed in conjunction with the front arc-shaped groove 56. The front tensioning assembly is located in the finger plate cavity 57 and slides in conjunction with the front arc-shaped groove 56. A heat dissipation assembly is adhesively bonded to the rear end of the palm plate 6. In this embodiment, the specific operation process is as follows:

[0035] Place the patient's hand on top of the palm plate 6, then spread each finger and place it in the gap between each pair of rear and front finger clamping components. The fingers are then fixed by the front and rear finger clamping components. By activating the bending component, the finger plate 11 is rotated upwards or downwards relative to the palm plate 6. Through the clamping of the fingers by the front and rear finger clamping components, the finger plate 11 causes the middle phalanx to extend upwards or bend downwards relative to the proximal phalanx, thus activating the finger joint. At the same time, the bending component extends and retracts to control the finger plate 11 away from the palm plate 6, stretching the finger joint. By setting a rear tensioning component, the transmission component drives the tensioning component to extend outwards in the horizontal direction, controlling the five fingers to complete the opening and closing tensioning action in the horizontal direction. Simultaneously, the cylinder 7 is activated to move the support 5 and the palm plate 6 forward to stretch the wrist joint, and at the same time, it works in conjunction with the bending component to achieve synchronous bending and opening and closing tensioning actions of the fingers. When the fingers are bent, the heat dissipation component automatically blows air into the palm to improve the comfort of the palm area.

[0036] Example 2, based on Example 1, such as Figure 10 As shown, the post-tensioning assembly includes two sickle-shaped rear swing rods 44 arranged facing each other in the palm plate chamber 54. Each rear swing rod 44 has three rear sliding air rods 43 integrally fixed at equal intervals on its upper end surface, which cooperate with the rear arc-shaped groove 42. The rear swing rods 44 and the rear sliding air rods 43 are connected by an air passage 26. The process is as follows:

[0037] The two rear swing rods 44, which are slidably arranged in the palm plate chamber 54, play a role in fixing and limiting the rear sliding air rod 43 and the rear fixed chamber 10, maintaining the stability of the rear fixed chamber 10 and preventing the rear fixed chamber 10 and the rear sliding air rod 43 from detaching from the rear arc groove 42. The rear swing rods 44 and the rear sliding air rod 43 are connected by an air passage 26, and the upper end of the rear sliding air rod 43 extends to the air delivery pipe 25, which can deliver the gas delivered at the air delivery hose 41 to the inside of the air delivery pipe 25.

[0038] Example 3, based on Example 2, such as Figure 4 As shown, the rear clamping assembly includes a rear fixed chamber 10 fixedly inserted from the bottom by a rear sliding air rod 43. The rear fixed chamber 10 has expansion slots 58 on both the front and rear sides of its upper end. Two relatively movable hatch covers 16 are slidably connected within the expansion slots 58, and the two hatch covers 16 are elastically connected by an elastic band 18. A lifting mechanism is provided between the bottom of the rear fixed chamber 10 and the two hatch covers 16 to control the opening and closing of the two hatch covers 16. Airbag clamping slots 23 are symmetrically provided on the left and right sides of the rear fixed chamber 10. Clamping airbags 24 are adhesively bonded within the airbag clamping slots 23. Air delivery pipes 25 are fixedly connected to the inward side of the clamping airbags 24. The other ends of the two air delivery pipes 25 are perpendicularly and three-way connected to the rear sliding air rod 43 inserted into the rear fixed chamber 10. The process is as follows:

[0039] The opening mechanism inside the rear fixed chamber 10 controls the opening of the cover 16 of each rear fixed chamber 10. The covers 16 of every two adjacent fixed chambers come into contact, limiting the upper part of the fingers. An air pump 36 is installed in one corner of the tabletop 102. The air pump 36 has two air supply hoses 41 at its outlet. Each air supply hose 41 is divided into two branches (not shown in the figure) at its outlet, which are respectively connected to the air inlet of each rear swing rod 44. The air enters the rear sliding air rod through the air passage 26 inside the rear swing rod 44. Inside 43, air is supplied to the clamping airbag 24 through the three-way assembly to each air supply pipe 25, thereby controlling the inflation of the clamping airbag 24. The surface of the clamping airbag 24 is provided with soft barbs. When the clamping airbag 24 inflates, it massages and stimulates both sides of the proximal phalanx, and continues to increase the air pressure to increase the friction on the patient's fingers and clamp the proximal phalanx of the patient. Multiple elastic bands 18 are provided below the two hatches 16. When the lifting mechanism descends, the two hatches 16 are closed by the tension of the elastic bands 18.

[0040] Example 4, based on Example 3, such as Figure 4As shown, the lifting mechanism includes a lifting protrusion 17 elastically connected to the bottom of the rear fixed compartment 10. Several tension springs 37 are fixed to the bottom of the lifting protrusion 17, and the other end of the tension springs 37 is fixed to the bottom of the rear fixed compartment 10. A lifting pin 19 is fixed to the bottom of the lifting protrusion 17, and a permanent magnet 20 is fixed to the lower end of the lifting pin 19. The lifting pin 19 is slidably sleeved in a sleeve 21. An electromagnet 22 is provided at the bottom of the inner cavity of the sleeve 21. The other end of the sleeve 21 is fixed to the bottom of the rear fixed compartment 10. The lifting protrusion 17 is chamfered to fit with two compartment covers 16. When the lifting protrusion 17 lifts, both compartment covers 16 open outward to fix the fingers. The process is as follows:

[0041] By installing an electromagnet 22 inside the sleeve 21, when the electromagnet 22 is powered, the repulsive force generated by the electromagnet 22 on the permanent magnet 20 drives the lifting pin 19 to be lifted upward inside the sleeve 21, thereby causing the lifting protrusion 17 to move upward. When the lifting protrusion 17 moves upward, the inclined surface at the top pushes open the two covers 16, thereby limiting the area above the finger. Each cover 16 has a layer of elastic film glued to the bottom to prevent the cover 16 from directly contacting the finger and causing damage.

[0042] Example 5, based on Example 3, such as Figure 7 As shown, the bending assembly includes a push cylinder 30 fixed to the front end of the rear fixed chamber 10. A stabilizing block 31 is fixed to the output end of the push cylinder 30. A bending cylinder 32 and a support rod 35 are vertically arranged on the other side of the stabilizing block 31. A flipping connecting block 34 is hinged to the bending cylinder 32 and the support rod 35. The process is as follows:

[0043] A plastic shell 33 is fitted onto the bending assembly. A push cylinder 30 is fixedly installed at the front end of the rear fixed chamber 10. When the push cylinder 30 is activated, it pushes the stabilizing block 31, support rod 35, bending cylinder 32 and flip connecting block 34 to move, thereby causing the front finger clamping assembly to move away from the rear finger clamping assembly, thus stretching the finger joint. When the bending cylinder 32 is activated, the output shaft of the bending cylinder 32 moves back and forth, causing the flip connecting block 34 to rotate, thereby adjusting the rotation angle of the front finger clamping assembly, and thus causing the finger to extend upward or bend downward.

[0044] Example 6, based on Example 5, such as Figure 2 As shown, the front clamping finger assembly includes a front fixing chamber 28 that is fixed to and flips the connecting block 34, and the front fixing chamber 28 has the same structure as the rear fixing chamber 10. The process is as follows:

[0045] The anterior fixation chamber 28 and the posterior fixation chamber 10 have the same structure and act on the middle phalanx and proximal phalanx, respectively.

[0046] Example 7, based on Example 6, such as Figure 9As shown, the pre-tensioning assembly includes two left and right front swing rods 55 arranged on the same arc within the finger plate chamber 57. A front sliding air rod 27 is integrally fixed to both sides of the upper end face of the left front swing rod 55, and three front sliding air rods 27 are integrally fixed to the upper end face of the right front swing rod 55 at equal intervals. All front sliding air rods 27 slide in cooperation with the front arc-shaped groove 56. Each front sliding air rod 27 is fixedly inserted through the bottom of the front fixed chamber 28, and each front sliding air rod 27 is vertically and three-way fixedly connected to the air supply pipes 25 on both sides of the corresponding front fixed chamber 28. The process is as follows:

[0047] The two front swing rods 55, which are slidably arranged in the plate chamber 57, play a role in fixing and limiting the front sliding air rod 27 and the front fixed chamber 28, maintaining the stability of the front fixed chamber 28 and preventing the front fixed chamber 28 and the front sliding air rod 27 from detaching from the rear arc groove 42. The front swing rods 55 and the front sliding air rod 27 are connected by an air passage 26, and the upper end of the front sliding air rod 27 extends to the air delivery pipe 25, which can deliver the gas delivered at the air delivery hose 41 to the inside of the air delivery pipe 25.

[0048] Example 8, based on Example 1, such as Figure 9 As shown, the transmission assembly includes a rack 49 fixed to the bottom of the slide groove 4, a power input gear 48 meshing with the rack 49, a gear connecting rod coaxially fixed to the power input gear 48, a power output gear 46 coaxially fixed to the upper end of the gear connecting rod, a transmission gear 14 meshing with the power output gear 46, and oscillating gears 45 meshing with the power output gear 46 and the transmission gear 14 on their respective sides. The upper ends of the two oscillating gears 45 are respectively fixed to the corresponding rear oscillating rods 44. The process is as follows:

[0049] The power input gear 48, power output gear 46, transmission gear 14, and swing gear 45 are all rotatably mounted inside the palm plate 6. When the cylinder 7 pushes the support 5 to move the palm plate 6, the palm plate 6 drives the power input gear 48 to move. Through the meshing of the power input gear 48 and the rack 49, the power input gear 48 rotates on the rack 49 while moving, and at the same time drives the gear connecting rod to rotate, which in turn drives the power output gear 46 to rotate. The power output gear 46 drives one of the swing gears 45 and the transmission gear 14 to rotate relative to each other. The transmission gear 14 drives the other swing gear 45 to rotate relative to the first swing gear 45. Finally, it drives the two rear swing rods 44 to swing in a direction away from or close to each other. Through the action of the rear sliding air rod 43 and the rear finger clamping assembly, when the palm plate 6 moves with the support 5, it can automatically complete the opening and closing stretching action of the five fingers in the horizontal direction, while stretching the wrist joint, and simultaneously cooperate with the bending assembly to realize the synchronous bending and opening and closing stretching action of the fingers.

[0050] Example 9, based on Example 1, such as Figure 8As shown, the finger plate connecting assembly includes a stabilizing connecting rod 52 fixed to the front end face of the palm plate 6, and a sliding connecting rod 53 hinged to the other end of the stabilizing connecting rod 52. A stabilizing sliding groove 51 is provided at one end of the finger plate 11 near the palm plate 6, and the stabilizing sliding groove 51 provides a limiting sliding engagement with the stabilizing connecting rod 52, as follows:

[0051] By hinged connecting rod 52 and sliding connecting rod 53, when finger plate 11 is flipped relative to palm plate 6, sliding connecting rod 53 rotates relative to connecting rod 52. By providing a stabilizing sliding groove 51, when finger plate 11 moves away from palm plate 6, stabilizing connecting rod 52 slides in stabilizing sliding groove 51. By providing finger plate connecting assembly, the connection between finger plate 11 and palm plate 6 is maintained, preventing finger plate 11 from shifting position when the front finger clamping assembly moves on finger plate 11.

[0052] Example 10, based on Example 1, such as Figure 2 As shown, the palm plate 6 has a palm hole 9, and an anti-loosening strip 13 is arranged around the palm hole 9. The heat dissipation component includes an elastic ball 15 that is adhesively bonded to the edge of the palm hole 9. The elastic ball 15 is adhesively bonded to the bottom of the anti-loosening strip 13. Several air holes 8 are opened on the upper surface of the elastic ball 15, and the air inside the elastic ball 15 communicates with the outside through the air holes 8. A one-way valve 2 is provided on one side of the lower end of the elastic ball 15. External air can only enter the interior of the elastic ball 15 through the one-way valve 2, as follows:

[0053] When the fingers are closed, the palm of the hand bulges up, causing the anti-loosening band 13 to move upward. At this time, the anti-loosening band 13 at the lower end of the palm plate 6 tightens, pushing the elastic ball 15 upward so that the elastic ball 15 fits against the palm, providing support and massage to the palm and improving hand comfort. At the same time, when the elastic ball 15 is squeezed, the gas inside the elastic ball 15 is blown out from the air hole 8, blowing air onto the palm to dissipate heat from the hand. When the fingers are straightened, the palm straightens, at which time the elastic ball 15 returns to its original position, and at the same time, it is quickly replenished with air through the one-way valve 2.

[0054] Working principle: During use, place the patient's hand above the palm plate 6, then spread each finger and place it in the gap between each pair of rear and front finger clamping components. The bracket 3 supports the patient's arm. A controller is installed on the tabletop 102, and the cylinder, air pump 36, pushing cylinder 30, bending cylinder 32, and electromagnet 22 are all electrically connected to the controller. By synchronously activating the lifting mechanism in the front and rear fixing chambers 28 and 10, the cover 16 of each front and rear fixing chamber 10 is opened, and the covers 16 of each pair of adjacent fixing chambers contact each other, limiting the upper part of the fingers. An air pump 36 is installed in one corner of the tabletop 102, and two air delivery hoses 41 are installed at the air outlet of the air pump 36. Each air delivery hose 41 has an air outlet... Two separate air inlets (not shown in the diagram) connect to the air inlets of each front swing rod 55 and rear swing rod 44. Air enters the front sliding air rod 27 and rear sliding air rod 43 through the air passages 26 inside the front and rear swing rods 55 and 44, respectively. Then, through a three-way connector, air is supplied to each air delivery pipe 25 to control the inflating of the clamping airbag 24. The surface of the clamping airbag 24 is covered with soft barbs. When the clamping airbag 24 inflates, it massages and stimulates both sides of the proximal and middle phalanges. Continuing to increase the air pressure increases the friction on the patient's fingers, clamping the proximal and middle phalanges. Activating the push cylinder 30 moves the stabilizing block 31, support rod 35, bending cylinder 32, and flipping connecting block 34, thus moving the front finger clamp. The component moves away from the rear finger clamping component, thereby stretching the finger joint. By activating the bending cylinder 32, the output shaft of the bending cylinder 32 reciprocates, driving the flipping connecting block 34 to rotate, thereby adjusting the rotation angle of the front finger clamping component, which in turn causes the finger to extend upward or bend downward. The two front swing rods 55 slidably arranged in the finger plate cavity 57 fix and limit the front sliding air rod 27 and the front fixed chamber 28, maintaining the stability of the front fixed chamber 28 and preventing the front fixed chamber 28 and the front sliding air rod 27 from disengaging from the rear arc-shaped groove 42. The two rear swing rods 44 slidably arranged in the palm plate cavity 54 fix and limit the rear sliding air rod 43 and the rear fixed chamber 10, maintaining the stability of the rear fixed chamber 10 and preventing the rear fixed chamber 10 from disengaging from the rear fixed chamber 10. When the cabin 10 and the rear sliding pneumatic rod 43 disengage from the rear arc-shaped groove 42, and the cylinder 7 pushes the support 5 to move the palm plate 6, the palm plate 6 drives the power input gear 48 to move. Through the meshing of the power input gear 48 and the rack 49, the power input gear 48 rotates on the rack 49 while moving, and at the same time drives the gear connecting rod to rotate, which in turn drives the power output gear 46 to rotate. The power output gear 46 drives one of the swing gears 45 and the transmission gear 14 to rotate relative to each other. The transmission gear 14 drives the other swing gear 45 to rotate relative to the first swing gear 45. Finally, it drives the two rear swing rods 44 to swing in a direction that moves away from or closer to each other. The action of the rear sliding pneumatic rod 43 and the rear finger clamping assembly enables the palm plate 6 to move with the support 5.It can automatically perform opening and closing stretching movements of the five fingers in the horizontal direction, while simultaneously stretching the wrist joint. It also works in conjunction with a bending component to synchronously bend and open / close the fingers. When the fingers are closed, the palm bulges, causing the anti-loosening band 13 to move upwards. At this time, the lower section of the anti-loosening band 13 on the palm plate 6 tightens, pushing the elastic ball 15 upwards so that it fits against the palm, providing support and massage, improving hand comfort. Simultaneously, when the elastic ball 15 is compressed, the air inside it is blown out through the air hole 8, cooling the palm and further improving patient comfort.
