Description

Technical Field

[0001] The invention specifically relates to a multifunctional rehabilitation exercise device for hand injuries. Background Art

[0002] The hand is the most commonly used organ in daily life and work. Since the hand does not have much protection in most cases and needs to constantly contact various tools and objects, its reflex support and bracing in the event of trauma (such as falls or collisions) also makes it the most vulnerable part of the body.

[0003] The treatment of hand injuries includes conservative treatment, surgical treatment and drug treatment. For hand injuries treated conservatively and surgically, after ensuring wound healing through immobilization, staged rehabilitation training can be carried out under the doctor's permission, including raising the affected limb, grasping training, joint extension and resistance training. There is currently no device specifically used for rehabilitation training of hand injuries, and patients need to use various auxiliary tools for training on their own, which is more troublesome. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a multifunctional rehabilitation training device for hand injuries, which can help patients perform rehabilitation training for various hand injuries.

[0005] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a multifunctional rehabilitation exercise device for hand injuries, comprising a support frame, a hand fixing mechanism and an auxiliary movement mechanism;

[0006] The hand fixing mechanism comprises a sleeve, an airbag and a splint, wherein the airbag is circumferentially arranged on the inner wall of the sleeve, and the two splints are symmetrically arranged on the outer walls of both sides of the sleeve and can move along the axial direction of the splints, the splints are connected to each other through an adjuster, and the adjuster can drive the two splints to move relative to each other, and the sleeve is connected to a grip ball through a sling;

[0007] The auxiliary motion mechanism includes a first slide rail, a slider, a fixed rod and a driver. The first slide rail is arc-shaped and fixedly mounted on a support frame. The slider is slidably connected to the first slide rail. The two ends of the fixed rod are respectively connected to the slider and the sleeve. The driver is arranged on the slider and can drive the slider to move in the first slide rail.

[0008] When in use, the patient can pass the hand through the sleeve, fix the arm position by inflating the airbag, and move the shackle relative to the sleeve to both sides of the wrist. The two splints can be moved towards each other by the regulator to fix the wrist and keep the joint straight. At the same time, the patient can also hold the grip ball for grip training. The driver drives the slider to move back and forth in the first slide rail, thereby driving the arm to rotate along the arc trajectory and rotate relative to the body, thereby completing the training action of lowering and raising the affected limb.

[0009] The beneficial effects of the above-mentioned multifunctional rehabilitation exercise device for hand injuries are: it can not only help patients lift up the patients and do reciprocating limb lifting training, but also allow patients to do grasping training through a grip ball, and can also keep the patient's joints straight through a splint.

[0010] Furthermore, the sleeve includes an outer cylinder layer and an inner cylinder layer, the inner cylinder layer is rotatably sleeved in the outer cylinder layer, a limiting slide groove is circumferentially provided on the inner wall of the outer cylinder layer, a limiting slider is provided on the outer wall of the inner cylinder layer, and the limiting slider is slidably connected to the limiting slide groove.

[0011] After the patient passes through the inner tube layer and is fixed inside, he can rotate relative to the outer tube layer. The limit slider slides in the limit slide groove, allowing the patient's hand to have a certain rotation space, which is convenient for the patient to adjust to a more comfortable angle.

[0012] Furthermore, the regulator includes a connecting rod, a sliding rod and a threaded tube, the clamping plates are connected to the connecting rod, the connecting rod is L-shaped, and one end away from the clamping plate is arranged in a direction close to each other and is provided with an external thread, and the thread directions of the two ends of the threaded tube are opposite, and are respectively threadedly connected to the two connecting rods;

[0013] The outer wall of the outer cylinder layer is provided with a T-shaped groove and a groove along the axial direction, one end of the sliding rod is slidably connected to the T-shaped groove, and the other end is connected to the threaded pipe, and the clamping plate is slidably connected to the groove.

[0014] After the patient's hand passes through the inner tube layer, the splint is moved along the axial direction of the sleeve to the outside of the groove, and the slide bar slides in the T-slot to prevent the regulator from falling off. After moving to both sides of the hand joint, the threaded tube can be rotated to drive the two connecting rods to move towards each other, thereby driving the splint to clamp the hand joint and keep the joint straight.

[0015] Furthermore, the driver comprises a motor, a dial wheel and a lever, wherein the motor is arranged on the slider and connected to the dial wheel, the lever is arranged on the outer wall of the dial wheel at even intervals around the circumference, and the fixing rod is rotatably connected to the slider;

[0016] The first slide rail includes an arc rail and a passive rod. Two arc rails are provided in parallel and are interconnected at both ends. A plurality of passive rods are arranged between the two arc rails and are evenly spaced around the circumference of the arc rails. The rotation of the dial wheel can drive the dial rod to be inserted between the passive rods.

[0017] The rotation of the motor can drive the rotation of the dial wheel, and then the lever is pushed on the passive rod to make the slider slide in the arc track. After reaching the end, it slides into another arc track and is located on the other side of the passive rod, so that it can slide back and forth in the two arc tracks and drive the sleeve to slide back and forth circumferentially through the fixed rod, thereby helping the patient's affected limb to perform reciprocating limb lifting movements.

[0018] Furthermore, universal wheels are provided at the bottom of the support frame.

[0019] The support frame can be easily moved by the universal wheels to adjust its position relative to the patient.

[0020] Furthermore, it also includes a resistance training mechanism, including a push rod, a spring, a rotating shaft and a push plate. The support frame is provided with a fixed plate, the push rod is plugged into the fixed plate, the spring is sleeved on the push rod, and the two ends are respectively connected to the push rod and the fixed plate, the rotating shaft is rotatably connected to the support frame, and a plurality of push plates are evenly spaced around the circumference, and the push plate can abut against one end of the push rod away from the fixed plate.

[0021] The patient can place his palm on the rotating shaft and rotate the push plate toward the palm with his fingers, which can make the push plate on the other side rotate and push the push rod. The spring can provide resistance. After completing one rotation, the spring drives the push rod to reset, and the next finger grasping training can begin.

[0022] Furthermore, the resistance training mechanism also includes a latch pin, a plurality of which are arranged in parallel on the push rod, and a pin hole is provided at one end away from the push plate, and the latch pin can be inserted into the pin hole.

[0023] After the spring is compressed, it can be inserted into the pin hole on the other side of the support frame through the pin hole. According to the force adjustment of the resistance training, a corresponding number of push rods can be released to contact the push plate to adjust the resistance.

[0036] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0037] See also Figures 1 to 6 The present invention provides a multifunctional rehabilitation exercise device for hand injuries, including a support frame 10, a hand fixing mechanism 20 and an auxiliary movement mechanism 30. After the position and posture of the patient's hand are fixed by the hand fixing mechanism 20, rehabilitation training is convenient, and the auxiliary movement mechanism 30 can be used to help the patient complete rehabilitation exercises.

[0038] Specifically, Figures 1 to 3As shown, the hand fixing mechanism 20 includes a sleeve 21, an airbag 22 and a splint 23. The airbag 22 is circumferentially arranged on the inner wall of the sleeve 21. After the hand passes through the sleeve 21, the hand is fixed in the sleeve 21 by the expansion of the airbag 22, which can help the patient fix the hand position and is relatively labor-saving. Two splints 23 are symmetrically arranged on the outer wall of the sleeve 21. Grooves are axially provided on both sides of the sleeve 21. The splints 23 are slidably connected to the grooves, and the two splints 23 are connected to each other through an adjuster 24, which can clamp the hand joints. The sleeve 21 is also connected to a grip ball 213 through a sling, which can be used for grip training.

[0039] In this embodiment, the regulator 24 includes a connecting rod 241, a sliding rod 242 and a threaded tube 243. The connecting rod 241 is provided on each of the splints 23. The connecting rod 241 is L-shaped, and the other end is arranged in a direction close to each other and is provided with an external thread. The thread directions of the two ends of the threaded tube 243 are opposite, and they are respectively threadedly connected with the two connecting rods 241. A T-shaped groove 2111 is axially provided on the outer wall of the sleeve 21. One end of the sliding rod 242 is connected to the threaded tube 243, and the other end is slidably connected to the T-shaped groove 2111. After the patient's joint passes through the sleeve 21, the splint 23 can be slid out of the groove and located on both sides of the joint. At this time, the threaded tube 243 and the sliding rod 242 are also driven to move together. Rotating the threaded tube 243 can drive the two connecting rods 241 to move relative to each other, thereby driving the two splints 23 to move toward each other, clamping the patient's hand joint, and keeping the clamping state through the threaded tube 243, so that it is convenient for the patient to keep the joint straight to complete the training action.

[0040] Specifically, the sleeve 21 includes an outer cylinder layer 211 and an inner cylinder layer 212. The inner cylinder layer 212 is sleeved inside the outer cylinder layer 211. The inner wall of the outer cylinder layer 211 is provided with a limit slide groove around the circumference. The outer wall of the inner cylinder layer 212 is provided with a limit slider 32. The limit slider 32 is slidably connected with the limit slide groove, so that the inner cylinder layer 212 can rotate relative to the outer cylinder layer 211. After the arm is fixed by the airbag 22, there is a certain rotation space, which is convenient for the patient to adjust. After being fixed by the splint 23, since the splint 23 is connected to the outer cylinder layer 211 through the slide rod 242, the hand can be completely fixed and cannot rotate.

[0041] Specifically, Figure 1 and Figure 4As shown, the auxiliary motion mechanism 30 includes a first slide rail 31, a slider 32, a fixed rod 33 and a driver 34. The first slide rail 31 is in an arc shape, fixedly arranged on the support frame 10, and bends from the bottom to the top, which is the trajectory of the patient's affected limb lifting. The slider 32 is slidably connected to the first slide rail 31, and the sleeve 21 is connected to the slider 32 through the fixed rod 33. The slider 32 is driven by the driver 34 to move back and forth in the first slide rail 31, which can help the patient's affected limb to lift the limb reciprocally. In this embodiment, the driver 34 includes a motor, a dial wheel 341 and a dial rod 342. The motor is arranged in the slider 32, the dial wheel 341 is rotatably arranged on the slider 32 and connected to the motor, and the dial rod 342 is evenly arranged on the circumferential outer wall of the dial wheel 341 around the circumference. The first slide rail 31 includes two arc rails 311 arranged in parallel, and the two ends of the two arc rails 311 are connected, so that the slider 32 can enter from one arc rail 311 into the other arc rail 311, and a passive rod 312 is provided between the two arc rails 311. Multiple passive rods 312 are evenly arranged around the trajectory of the arc rails 311, and the lever 342 can be inserted between the passive rods 312. The fixed rod 33 is rotatably connected to the slider 32.

[0042] The rotation of the motor can drive the dial wheel 341 to rotate, and the lever 342 can be inserted between the passive rods 312, thereby driving the slider 32 to slide in the arc track 311. After reaching the end, it enters another arc track 311 and is located on the other side of the passive rod 312, thereby continuing to move, so that the slider 32 drives the sleeve 21 to rotate reciprocatingly upward and downward, helping the patient's affected limb to do limb lifting training.

[0043] Specifically, Figure 1 , Figure 5 and Figure 6 As shown, the resistance training mechanism 40 is also included, including a fixed plate 41, a push rod 42, a spring 43, a rotating shaft 44 and a push plate 45. The fixed plate 41 is set on the support frame 10, the push rod 42 is inserted on the fixed plate 41, and a baffle 421 is provided at the end away from the fixed plate 41. The spring 43 is sleeved on the push rod 42, and the two ends are respectively connected to the baffle 421 of the push rod 42 and the fixed plate 41. The rotating shaft 44 is rotatably connected to the support frame 10 and is located at the end of the push rod 42. The push plates 45 are evenly spaced around the rotating shaft 44. After the hand is fixed by the sleeve 21, the palm can be extended to the rotating shaft 44, and the fingers are gripped inward to drive the push plate 45 to rotate, so that the push plate 45 on the other side abuts against the baffle 421 and pushes the push rod 42 to move axially. The spring 43 can provide resistance, so that the patient can complete the grip training. After one exercise is completed, the push rod 42 is reset under the action of the spring 43, thereby enabling reciprocating training.

[0044] In this embodiment, a plurality of push rods 42 are provided in parallel, and each of them is provided with a pin hole 422. After the spring 43 is compressed, the pin 423 is inserted into the pin hole 422 on the other side of the fixing plate 41 to prevent the push rod 42 from resetting. During resistance training, the push rods 42 can be adjusted according to actual needs, and the pin 423 can be removed to release a corresponding number of push rods 42, thereby adjusting the resistance.

[0045] Specifically, universal wheels are provided at the bottom of the support frame 10, and the entire device can be easily moved through the universal wheels, so that the patient can adjust it to a suitable position for use.

[0046] The working principle of the above-mentioned multifunctional rehabilitation exercise device for hand injuries is: move the support frame 10 to the patient, pass the affected limb through the sleeve 21, and fix it by inflating the airbag 22. If the joint needs to be fixed, the splint 23 can be slid out to both sides of the joint, and the splint 23 is driven to clamp the hand joint through the rotation of the threaded tube 243 to keep it straight. During limb lifting training, the motor drives the dial wheel 341 to rotate, and the lever 342 drives the slider 32 to move in the arc frame through the passive rod 312, thereby driving the affected limb to rotate up and down. During grip training, the training can be completed through the grip ball 213, or it can be extended to the rotating shaft 44, and the push rod 42 can be driven to move by grasping the push plate 45 to complete the resistance grip training, and the resistance can be adjusted.

[0047] The use of the above-mentioned multifunctional rehabilitation exercise device for hand injuries can help patients perform various hand rehabilitation training, including limb lifting training, grip resistance training, and joint extension, etc., and is easy to use and has good training effects and convenience.
