Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation therapy, in particular to an upper limb combined exerciser for stroke rehabilitation. Background Art

[0002] Stroke, also known as stroke, is an acute cerebrovascular disease that mostly occurs in middle-aged and elderly people and has a high disability rate. Some stroke patients are unwilling to move due to movement dysfunction, and some patients feel that they must stay in bed and rest after a stroke. However, for stroke patients, long-term bed rest may bring many adverse consequences.

[0003] Stroke rehabilitation is mainly divided into three levels. Level one rehabilitation mainly involves good limb positioning, passive joint movement, early bedside sitting and sitting balance training. The most important thing in the acute phase is to prevent recurrent stroke and complications. Level two rehabilitation mainly strengthens the active movement of the affected limb and combines it with daily life activities, conducts relevant occupational therapy, speech therapy, psychotherapy, and traditional rehabilitation therapy, reduces the degree of muscle spasm in the hemiplegic limb and avoids strengthening abnormal movement patterns. Level three rehabilitation is routine exercise to maintain function. Both level two and level three rehabilitation require patients to actively use various exercise devices, such as upper limb exercisers to exercise upper limb ability.

[0004] Existing upper limb exercisers are mainly divided into two types. One is the wheel-type exerciser in the park, also known as the shoulder joint trainer, which exercises the flexibility of the upper limbs by rotating the wheel with the patient's upper limbs. However, the rotation of the wheel is relatively light, so the strength training effect is poor. Therefore, a second type of pulling device is needed for strength training. The pulling device is that the patient's upper limbs are constantly pulling down and raising their hands. The activity trajectory is monotonous and the range is small, and the effect of exercising the flexibility of the upper limbs is poor. The two devices cannot exercise at the same time. Therefore, an upper limb combination exerciser that integrates flexibility training and strength training is designed. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an upper limb combined exerciser for stroke rehabilitation to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an upper limb combination exerciser for stroke rehabilitation, comprising a bracket, a rotating frame passing through one side of the bracket; and a friction disk is sleeved on the outside of the rotating frame; a handle glove is connected to the outer surface of the rotating frame, and a pull frame is connected to the inside of the handle glove, a pull plate is connected to one side of the inside of the bracket through a tension spring and a telescopic rod, and a cable is connected between the pull frame and the pull plate, and fixed sleeves are sleeved on both ends of the cable; a screw rod passes through one side of the pull plate, and one end of the screw rod is connected to a mounting frame, and a friction plate is connected to one side of the mounting frame.

[0007] By adopting the above technical scheme, in the early stage of rehabilitation, when the patient's strength has not yet recovered, the patient can grab the handle glove with his hand to make the handle glove revolve, so that the rotating frame rotates. At this time, the patient's arms and shoulders and back can all move, so as to facilitate the exercise of the flexibility of the patient's upper limbs; when the flexibility of the patient's limbs increases, the patient changes the operation of grabbing the handle glove to the thumb buckling the handle glove, and the patient's other four fingers pull the pull frame to displace the pull frame, and after the pull frame is displaced, the pull plate is driven to displace by the cable, and the cable is prevented from falling off by the fixing sleeve. After the pull plate is displaced, the tension spring and the telescopic rod are extended, and at this time, the tension spring applies a force in the opposite direction to apply force to the patient's fingers, so as to facilitate the exercise of the patient's hand grip, and the pull plate drives the friction plate to displace through the mounting frame while displacing, so that the friction plate and the friction disk are offset, and at this time, the friction between the friction plate and the friction disk increases the rotation resistance of the rotating frame, and at this time, the patient needs to increase the upper limb strength to make the rotating frame continue to rotate, so as to facilitate the exercise of the patient's upper limb strength.

[0008] Furthermore, the rotating frame is rotatably connected to the bracket, and the glove is rotatably connected to the rotating frame.

[0009] By adopting the above technical solution, the patient can grasp the glove with his hand to make the glove revolve, thereby making the rotating frame rotate. At this time, the patient's arms and shoulders and back can all move, thereby facilitating the exercise of the flexibility of the patient's upper limbs.

[0010] Furthermore, the pull frame is slidably connected to the handle cover, and the pull plate is slidably connected to the bracket.

[0011] By adopting the above technical solution, the patient changes the operation of grasping the handle glove into buckling the handle glove with the thumb, and the patient pulls the pull frame with the other four fingers to displace the pull frame, and after the pull frame is displaced, the pull cable drives the pull plate to displace.

[0012] Furthermore, the screw rod is threadedly connected to the pull plate, and the screw rod is rotationally connected to the mounting frame.

[0013] By adopting the above technical solution, at the early stage of exercise, medical staff can rotate the screw rod to move the mounting frame and the friction plate closer to or away from the friction disk, thereby facilitating the adjustment of the strength.

[0014] Furthermore, four guide rods distributed in a ring array are fixed on the other side of the mounting frame, and the mounting frame is slidably connected to the pull plate through the guide rods.

[0015] By adopting the above technical solution, medical staff can rotate the screw rod to move the mounting frame, and at the same time, the mounting frame can be prevented from rotating and guided by the four guide rods on the other side of the mounting frame.

[0016] Furthermore, the friction plate is in contact with the friction disc, and the two fixing sleeves are rotatably connected to the pull frame and the pull plate respectively.

[0017] By adopting the above technical solution, the pull plate drives the friction plate to move through the mounting frame while displacing, so that the friction plate and the friction disk are against each other. At this time, the friction between the friction plate and the friction disk increases the rotation resistance of the rotating frame, and the fixed sleeve can rotate to ensure the shape of the cable, avoiding the cable being twisted off due to rotation.

[0018] Furthermore, a plurality of the tension springs and telescopic rods are provided, and the plurality of tension springs and telescopic rods are distributed in a ring array, and the pull plate and the mounting frame are made of aluminum alloy material.

[0019] By adopting the above technical solution, the pull plate is displaced to extend the tension spring and the telescopic rod. At this time, the tension spring applies force in the opposite direction to apply force to the patient's fingers, so as to exercise the grip strength of the patient's hand. The pull plate and the mounting frame are both made of aluminum alloy material, thereby reducing the weight of the structure.

[0020] Furthermore, the top and bottom of the bracket are connected to inspection doors, and dustproof nets are installed inside the two inspection doors.

[0021] By adopting the above technical solution, the setting of the inspection door facilitates the inspection of the internal structure. At the same time, due to the setting of the dustproof net, the air inside the bracket can exchange with the outside air, thereby increasing the heat dissipation effect of natural cooling on the friction plate and the friction plate, and the dustproof net can reduce the entry of dust and impurities.

[0022] Furthermore, two friction discs are provided, and two first screws are passed through the outer rings of the two friction discs. The two friction discs are detachably connected to the rotating frame through the four first screws.

[0023] By adopting the above technical solution, the medical staff removes the first screw and then the friction disc. Finally, the staff fits the friction disc and the rotating frame and then passes the first screw through and tightens it, thereby completing the friction disc replacement operation.

[0024] Furthermore, two friction plates are provided, and a positioning block is fixed on one side of each friction plate, positioning grooves are provided on the upper side and the lower side of the mounting frame, two second screws are passed through the top and the bottom of the mounting frame, and the two friction plates are detachably connected to the mounting frame through the second screws, the positioning grooves and the positioning blocks.

[0025] By adopting the above technical solution, the medical staff removes the second screw and then moves the friction plate horizontally to separate the friction plate from the mounting frame to complete the disassembly. Then the medical staff places the new friction plate on the side of the mounting frame. Then the medical staff fits the new friction plate to the mounting frame so that the positioning block on the side of the friction plate enters the positioning groove on the side of the mounting frame. Finally, the medical staff passes the second screw through and tightens it to complete the friction plate replacement operation.

[0026] In summary, the present invention mainly has the following beneficial effects:

[0027] 1. The present invention arranges the mounting frame, the friction plate and the friction disc. When the pull plate is displaced, the friction plate is driven to displace through the mounting frame, so that the friction plate and the friction disc are offset. At this time, the friction between the friction plate and the friction disc increases the rotation resistance of the rotating frame. At this time, the patient needs to increase the strength of the upper limbs to make the rotating frame continue to rotate, so as to exercise the upper limb strength of the patient; it is convenient to conduct synchronous strength and flexibility training of the upper limbs, and there is no need to use two training devices in two-step operation, which reduces the floor space and exercise time, thereby improving the rehabilitation efficiency;

[0028] 2. The present invention provides a rotating frame and a handle glove. In the early stage of rehabilitation, when the patient's strength has not yet recovered, the patient can grab the handle glove with his hand to make it revolve, thereby causing the rotating frame to rotate. At this time, the patient's arms and shoulders can all move, thereby facilitating the exercise of the patient's upper limb flexibility; facilitating the flexibility training of the upper limbs;

[0029] 3. The present invention is provided with a pull frame, a pull cable, a fixed sleeve, a pull plate, a tension spring and a telescopic rod. When the flexibility of the patient's limbs increases, the patient can hold the handlebar with his thumb and pull the pull frame with the other four fingers to move the pull frame. After the pull frame is moved, the pull plate is driven to move by the pull cable, and the fixed sleeve is used to prevent the pull cable from falling off. After the pull plate is moved, the tension spring and the telescopic rod are extended. At this time, the tension spring applies a force in the opposite direction to apply force to the patient's fingers, so as to exercise the grip strength of the patient's hands and facilitate strength training of the hands.

[0030] 4. The present invention arranges the screw rod and the mounting frame. In the early stage of exercise, the medical staff can rotate the screw rod to move the mounting frame and the friction plate closer to the friction disk, so that the stroke of the pull frame is reduced and the tension of the tension spring is reduced, thereby reducing the strength of the hand grip. In the later stage of exercise, the medical staff can reverse the screw rod to move the mounting frame and the friction plate away from the friction disk, increase the stroke of the pull frame and the tension of the tension spring, so that the patient needs to hold the pull rod tightly to make the friction plate and the friction disk fit together, thereby increasing the force output and thus increasing the effect of strength training; the strength can be adjusted flexibly, so that it is convenient for patients to use.

At this time, the patient's arms and shoulders and back can all move, so as to facilitate the exercise of the patient's upper limb flexibility; the handle glove 3 is connected to the inside of the pull frame 4, and one side of the inside of the bracket 1 is connected to a pull plate 7 through a tension spring 8 and a telescopic rod 9.

When the pull plate 7 moves, it drives the friction plate 12 to move through the mounting frame 10, so that the friction plate 12 abuts against the friction disc 13. At this time, the friction between the friction plate 12 and the friction disc 13 increases the rotation resistance of the rotating frame 2.

[0043] See also Figure 1-Figure 3 In the above embodiment, the top and bottom of the bracket 1 are connected with inspection doors 18 to facilitate the inspection of the internal structure; dustproof nets 19 are installed inside the two inspection doors 18, so that the air inside the bracket 1 can exchange with the outside air, thereby increasing the heat dissipation effect of natural cooling on the friction plate 12 and the friction plate 12, and the dustproof nets 19 can reduce the entry of dust and impurities.

[0044] Embodiment 2:

[0045] On the basis of the above-mentioned first embodiment, in order to facilitate the replacement of the friction plate 12 and the friction disc 13, the following arrangement is adopted.

[0046] See, 2- Figure 6In the above embodiment, two friction discs 13 are provided, and two first screws 14 are passed through the outer rings of the two friction discs 13. The two friction discs 13 are detachably connected to the rotating frame 2 through four first screws 14. The medical staff removes the first screws 14 and then removes the friction disc 13. Finally, the staff fits the friction disc 13 with the rotating frame 2 and then passes through the first screws 14 and tightens them, thereby completing the replacement operation of the friction disc 13; two friction plates 12 are provided, and positioning blocks 17 are fixed on one side of the two friction plates 12. Positioning grooves 16 are opened on the upper side and the lower side of the mounting frame 10. The top and bottom of the mounting frame 10 are penetrated Two second screws 15 are inserted therethrough, and the two friction plates 12 are detachably connected to the mounting frame 10 through the second screws 15, the positioning grooves 16 and the positioning blocks 17. The medical staff removes the second screws 15 and then moves the friction plates 12 laterally to separate the friction plates 12 from the mounting frame 10 to complete the disassembly. Then the medical staff places the new friction plates 12 on the side of the mounting frame 10. Then the medical staff fits the new friction plates 12 with the mounting frame 10 so that the positioning blocks 17 on the side of the friction plates 12 enter the positioning grooves 16 on the side of the mounting frame 10. Finally, the medical staff passes the second screw 15 through and tightens it, thereby completing the replacement operation of the friction plates 12.

[0047] The implementation principle of the present invention is as follows: first, the construction personnel fix the bracket 1 on the ground by bolts, thereby completing the installation operation of the exerciser and placing the exerciser stably to prevent the bracket 1 from tipping over during exercise; in the early stage of rehabilitation, when the patient's strength has not yet recovered, the patient can grab the handle glove 3 with his hand to make the handle glove 3 revolve, thereby making the rotating frame 2 rotate, and at this time, the patient's arms and shoulders and back can all exercise, thereby facilitating the exercise of the flexibility of the patient's upper limbs;

[0048] When the flexibility of the patient's limbs increases, the patient changes the operation of grasping the handle glove 3 to buckling the handle glove 3 with the thumb, and the patient's other four fingers pull the pull frame 4 to displace the pull frame 4. After the pull frame 4 is displaced, the pull cable 5 drives the pull plate 7 to displace, and the fixing sleeve 6 prevents the pull cable 5 from falling off. After the pull plate 7 is displaced, the tension spring 8 and the telescopic rod 9 are extended. At this time, the tension spring 8 applies a force in the opposite direction to apply force to the patient's fingers, so as to exercise the patient's hand grip strength. When the pull plate 7 is displaced, the friction plate 12 is driven to displace through the mounting frame 10, so that the friction plate 12 and the friction disk 13 are against each other. At this time, the friction between the friction plate 12 and the friction disk 13 increases the rotation resistance of the rotating frame 2. At this time, the patient needs to increase the upper limb strength to make the rotating frame 2 continue to rotate, so as to exercise the patient's upper limb strength.

[0049] In the early stage of exercise, the medical staff can rotate the screw rod 11 to move the mounting frame 10 and the friction plate 12 closer to the friction disk 13, so that the stroke of the pull frame 4 is reduced and the tension of the tension spring 8 is reduced, thereby reducing the strength of the hand grip. In the late stage of exercise, the medical staff can reverse the screw rod 11 to move the mounting frame 10 and the friction plate 12 away from the friction disk 13, increase the stroke of the pull frame 4 and the tension of the tension spring 8, so that the patient needs to hold the pull rod tightly to make the friction plate 12 and the friction disk 13 fit together, increase the power output and thus increase the effect of strength training; at the same time, due to the setting of the dustproof net 19, the air inside the bracket 1 can communicate with the outside air, thereby increasing the heat dissipation effect of the friction plate 12 and the friction plate 12 by natural cooling, and the dustproof net 19 can reduce the entry of dust and impurities;

[0050] When the friction plate 12 and the friction disc 13 are severely worn due to long-term use, the medical staff can open the upper and lower inspection doors 18. When replacing the friction disc 13, the medical staff removes the first screw 14 and then removes the friction disc 13. Finally, the staff fits the friction disc 13 with the rotating frame 2 and then passes through the first screw 14 and tightens it, thereby completing the replacement operation of the friction disc 13; when replacing the friction plate 12, the medical staff removes the second screw 15 and then moves the friction plate 12 horizontally to separate the friction plate 12 from the mounting frame 10 to complete the disassembly, and then the medical staff places the new friction plate 12 on the side of the mounting frame 10, and then the medical staff fits the new friction plate 12 with the mounting frame 10, so that the positioning block 17 on the side of the friction plate 12 enters the positioning groove 16 on the side of the mounting frame 10, and finally the medical staff passes through the second screw 15 and tightens it, thereby completing the replacement operation of the friction plate 12; after the friction plate 12 and the friction disc 13 are replaced, the medical staff closes the inspection door 18.

[0051] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention.
