Description

Technical Field

[0001] The present invention specifically relates to a hand rehabilitation self-training device. Background Art

[0002] The hand is one of the most commonly used organs in daily life and work. Since the hand is not well protected in most cases and needs to constantly come into contact with various tools and objects, when there is an external injury (such as a fall or impact), its reflexive support and bracing also make it the most vulnerable part of the whole body.

[0003] During the phased rehabilitation training of hand injuries, it is necessary to exercise the grasping ability of the fingers, and the amount of exercise gradually increases. However, in the initial stage of rehabilitation, the patient's fingers cannot complete or are difficult to complete the action of clenching the fist by themselves, which slows down the recovery time, or requires the help of a caregiver to complete the training action, which is rather troublesome. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a hand rehabilitation self-training device, which can help patients complete the hand clenching training action by themselves.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: A hand rehabilitation self-training device, comprising a fixed seat, and a seat is provided on the fixed seat;

[0006] An auxiliary driving part, the auxiliary driving part includes a driving seat, driving wheels, a foot pedal, a driving gear cylinder, a transmission gear and a double-sided rack. The driving seat is arranged on the fixed seat. The driving gear cylinder is rotatably arranged in the driving seat, and there are two symmetrically arranged, and they are engaged through the transmission gear. Both ends of one of the driving gear cylinders are provided with driving wheels, and a foot pedal extending out of the driving seat is provided on the driving wheels. The double-sided rack is arranged between the two driving gear cylinders, and the two driving gear cylinders can alternately engage with the double-sided rack; and

[0007] A stretching part, the stretching part includes a fixing plate, finger sleeves and traction ropes. Fixing plates are provided on both sides of the fixed seat, and finger sleeves are provided on the fixing plates through connecting ropes. The finger sleeves are elastic. Traction ropes are connected to both sides of the finger sleeves, and the ends of the traction ropes away from the finger sleeves are respectively connected to both ends of the double-sided rack.

[0008] The patient can sit on the seat, place the palm to be exercised on the fixed plate, put on the finger cots, step on the two foot pedals with both feet respectively, and drive the active gear cylinder to rotate by rotating the foot pedals. The active gear cylinder drives another active gear cylinder to move in the same direction through the transmission gear. The two active gear cylinders alternately mesh with the double-sided rack, so as to drive the double-sided rack to reciprocate axially, and then drive the two traction ropes to reciprocate and pull the finger cots. One traction rope pulls the finger towards the palm direction, and the other traction rope pulls the finger towards the direction away from the palm, thus helping the patient's hand to reciprocally perform the palm clenching movement.

[0009] The beneficial effects of the above-mentioned hand rehabilitation self-help training device are as follows: The patient can help the hand complete the rehabilitation training by stepping on the feet, thus shortening the rehabilitation time, and can complete the training independently without bothering others, which is more convenient.

[0010] Furthermore, the stretching part further includes a limiting tube, which is fixedly arranged on the fixed seat and the driving seat. The part of the traction rope between the double-sided rack and the finger cot is inserted into the limiting tube. The limiting tube has a plurality of bends, and pulleys are arranged inside the bends.

[0011] The limiting tube can facilitate the layout of the direction of the traction rope, avoid the traction rope being exposed outside and being interfered by the outside world. Setting pulleys at the bends can reduce the friction of the traction rope.

[0012] Furthermore, one end of the traction rope close to the finger cot bifurcates into two ends, and respectively passes through both sides of the fixed plate to be connected with the finger cot. The corresponding limiting tube also bifurcates into two pipe orifices.

[0013] Since the finger needs to be bent towards the palm direction, the traction rope bifurcates into two, which are respectively located on both sides of the wrist, facilitating the balance of the pulling force.

[0014] Furthermore, it further includes an active training part, which includes a pulling plate and a spring. The pulling plate is connected with the driving seat through the spring; the traction rope includes a main rope and a sub-rope, the main rope and the sub-rope are respectively connected with the double-sided rack and the finger cot, connection balls are arranged on both the main rope and the pulling plate, and the sub-rope is detachably connected with the connection ball.

[0015] After the patient's hand can move independently, the main rope and the sub-rope can be disassembled, and after connecting the sub-rope with the pulling plate through the connection ball, the patient can pull the pulling plate by rotating the finger cot, and the spring can provide resistance, thus completing the anti-resistance training of grasping.

[0016] Furthermore, the connection ball is provided with a through hole through which the sub-rope can pass along the radial direction, and a threaded hole communicated with the through hole is also provided. A groove is arranged inside the through hole, and a locking bolt that can be inserted into the groove is threadedly connected inside the threaded hole.

[0017] When in use, pass the auxiliary rope through the through hole of the connecting ball, and then fix the auxiliary rope in the connecting ball by screwing in the locking bolt, completing the connection of the auxiliary rope with the main rope or the baffle, and the locking bolt.

[0018] Furthermore, two locking blocks are symmetrically hinged on the driving seat. One end of each locking block is located inside the driving seat and can respectively abut against both sides of the double-sided rack. The other end of each locking block is located outside the driving seat, is provided with a pin hole, and can be magnetically attracted to the surface of the driving seat.

[0019] When switching to the active training mode, the double-sided rack can be fixed by rotating the two locking blocks and making them abut against the double-sided rack. The locking blocks can be fixed by inserting pins into the pin holes to maintain the fixation of the double-sided rack. When in need of use, the pins can be taken out, the locking blocks can be rotated away from the double-sided rack, and they can be magnetically attracted to the driving seat.

[0020] Furthermore, an inflatable strap is provided on the fixing plate.

[0021] The inflatable strap can help the patient fix the wrist and palm on the fixing plate.

[0022] Furthermore, a slide rail is provided on the fixed seat, and the seat is slidably connected to the slide rail.

[0023] The position of the seat can be adjusted through the slide rail, facilitating the use by people of different body types. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Hereinafter, embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0036] Please refer to Figures 1 to 5 , the present invention provides a hand rehabilitation self-training device, including a fixed seat 10, an auxiliary drive part 20 and a stretching part 30. The patient drives the auxiliary drive part 20 to work through the feet, which can drive the stretching part 30 to help the hand complete the training action, so as to independently complete the rehabilitation exercise.

[0037] Specifically, a seat 11 is provided on the fixed seat 10 to facilitate the patient to sit and save physical strength. The auxiliary drive part 20 includes a drive seat 21, a drive wheel 22, a footrest 23, an active gear cylinder 24, a transmission gear 25 and a double-sided rack 26. The drive seat 21 is fixedly arranged on the fixed seat 10. The active gear cylinder 24 is rotatably connected inside the drive seat 21, and there are two symmetrically. The drive wheels 22 are arranged at both ends of one of the active gear cylinders 24, and both are connected with a footrest 23 located outside the drive seat 21 through a connecting rod. The connecting rod is rotatably connected with the footrest 23, and the two footrests 23 are symmetrically arranged along the radial direction of the drive wheel 22. Transmission gears 25 are engaged between both ends of the two active gear cylinders 24. The double-sided rack 26 is arranged at the middle position between the two active gear cylinders 24. Only half a circle of teeth is provided at the middle of the active gear cylinder 24, and the two active gear cylinders 24 can be alternately engaged with the double-sided rack 26.

[0038] After the patient sits on the seat 11, place both feet on the footrest 23 to do cycling exercises, driving the driving gear cylinder 24 to rotate from both ends together, and driving another driving gear cylinder 24 to rotate in the same direction through the transmission gear 25. When the two driving gear cylinders 24 rotate, their teeth alternately engage with both sides of the double-sided rack 26, thereby driving the double-sided rack 26 to move reciprocally along the axis.

[0039] Specifically, the stretching part 30 includes a fixing plate 31, finger sleeves 32 and traction ropes 33. Fixing plates 31 are provided on both sides of the fixing seat 10. Inflatable straps 311 are provided on the fixing plates 31 for fixing the hands of the patient on the seat 10. The finger sleeves 32 are arranged on the fixing plates 31 through connecting ropes and are used for wearing on the patient's fingers. The finger sleeves 32 are elastic and can tightly fit on the patient's hands. Two traction ropes 33 are connected to the finger sleeves 32, respectively located on both sides of the finger sleeves 32, and are respectively connected to both ends of the double-sided rack 26. The traction ropes 33 located on both sides of the fixing seat 10 are respectively connected to both sides of the end of the double-sided rack 26. Through the movement of the double-sided rack 26, the two traction ropes 33 can respectively pull the fingers towards the palm or away from the palm. In this embodiment, the traction line on the finger pulp side bifurcates into two ends and is connected to the finger sleeve 32, which is convenient for passing through both sides of the wrist to make the pulling force more balanced.

[0040] In this embodiment, a limiting tube 34 is fixedly provided on the fixing seat 10. After the traction rope 33 passes through the driving seat 21, it passes through the limiting tube 34 and then passes through to be connected to the finger sleeve 32. The limiting tube 34 has multiple bends for guiding the routing direction of the traction rope 33 to avoid being easily interfered by the outside when exposed. When the traction line bifurcates into two ends, the corresponding limiting tube 34 also bifurcates into two pipe orifices. As Figure 4 shown, pulleys 341 are provided at the bends of the limiting tube 34, and the traction line is slidably connected to the pulleys 341, which can reduce the friction force.

[0041] Specifically, as Figure 1 、 Figure 3 and Figure 5 shown, an active training part 40 is further included, which includes a pulling plate 41 and a spring 42. Pulling plates 41 are connected to the outer walls on both sides of the driving seat 21 through springs 42, and connecting balls 43 are provided on the pulling plates 41. The traction ropes 33 all include a main rope 331 and a sub-rope 332. The main rope 331 is connected to the double-sided rack 26, and its end passes through the driving seat 21 and is provided with a connecting ball 43. The sub-rope 332 can be detachably connected to the connecting ball 43. After detaching the sub-rope 332 from the main rope 331 and connecting it to the connecting ball 43 of the baffle, the patient's fingers can make inward curling or outward abduction movements with resistance, and the spring 42 can provide resistance, thereby enabling the patient to complete resistance training.

[0042] A through hole is radially formed in the upper edge of the connecting ball 43, and a threaded hole communicating with the through hole is also formed. The auxiliary rope 332 can pass through the through hole, and a groove is formed in the hole. A locking bolt 431 that can be inserted into the groove is threadedly connected in the threaded hole. When connecting, pass the auxiliary rope 332 through the connecting ball 43 and screw in the locking bolt 431 to fix the auxiliary rope 332 on the connecting ball 43.

[0043] On the top of the driving seat 21, two locking blocks 27 are symmetrically hinged. The two ends of the locking block 27 are respectively located inside and outside the driving seat 21. The inner end can respectively abut against both sides of the double-sided rack 26. The outer ends are both provided with pin holes and can be magnetically attracted to the surface of the driving seat 21. After the patient's finger recovers to a certain stage, it can be switched from the passive mode to the active mode. After connecting the auxiliary rope 332 of the traction rope 33 to the baffle, rotate the locking block 27 to abut against the double-sided rack 26, and pass the bolt 271 through the two pin holes for fixation, so as to keep the double-sided rack 26 fixed and avoid accidentally pulling the finger. When the locking block 27 is not in use, rotate it to the driving seat 21 and fix it magnetically.

[0044] Furthermore, a slide rail 12 is provided on the fixing seat 10, and the seat 11 is slidably connected to the slide rail 12, which is convenient for patients of different body types to use.

[0045] The working principle of the above-mentioned hand rehabilitation self-training device is as follows: In the early stage of rehabilitation, the patient can fix the hand on the fixing plate 31 and put on the finger sleeve 32, sit on the seat 11 and step on the foot pedal 23. The double-sided rack 26 is driven to reciprocate axially by the driving gear cylinder 24, so as to drive the finger sleeve 32 and the finger to reciprocally grip and stretch, assisting the patient to complete the rehabilitation training. When the patient's hand recovers to be able to perform resistance training, the traction rope 33 can be connected to the baffle, and the resistance is provided by the spring 42 to complete the resistance training. At the same time, the locking block 27 can be abutted against the double-sided rack 26 to lock the auxiliary driving part 20 and avoid misoperation.

[0046] When using the above-mentioned hand rehabilitation self-training device, when the patient has no self-training ability in the initial stage of rehabilitation, it can assist the patient to complete the training actions, improve the rehabilitation efficiency, and does not need to trouble others, which is more convenient. And it can also provide the function of resistance training in the later stage of rehabilitation, with strong practicability.
