Technical Field

[0001] The utility model relates to the technical field of rehabilitation, in particular to a rehabilitation assistive device. Background Art

[0002] Stroke is a common disease nowadays, which can easily cause motor dysfunction in one or both sides of the patient's limbs, making them unable to actively flex and extend. After being discharged from the hospital, stroke patients need to undergo rehabilitation training on their limbs to assist nerve recovery and prevent muscle atrophy in response to the damage to the limb motor nerves caused by the stroke. Traditional rehabilitation equipment, when assisting patients in rehabilitation, requires patients to sit in seats for a long time, which can cause back pain. In severe cases, it can further cause nerve damage, resulting in poor rehabilitation results and low practicality.

[0004] The above-mentioned public document restricts the patient's foot to a mounting plate, and then the patient extends his leg to push the mounting plate with resistance provided by the second spring. Although this can assist the patient's leg rehabilitation to a certain extent, it still has some shortcomings in actual use. For example, in the early stages of rehabilitation, the patient's legs are weak, and it is very difficult to actively extend the leg to push the mounting plate with resistance. It is impossible to passively achieve reciprocating rehabilitation training of the patient's legs by bending and straightening, which is very inconvenient to use.

[0020] Example, by Figure 1-4 It is given that the utility model includes a base 1, a seat 2 is fixedly installed on the top of the base 1, a groove 3 is opened on the top of the base 1, the groove 3 is located on one side of the seat 2, a driving mechanism and a T-shaped plate 8 are installed inside the groove 3, the driving mechanism passes through the T-shaped plate 8, the T-shaped plate 8 is located inside the groove 3 and extends to the top of the base 1, two leg rests are installed on one side of the T-shaped plate 8, the groove 3 is located between the two leg rests, the leg rest is composed of two adjustable support plates 9, the adjustable support plates 9 are composed of a hollow sleeve plate 91, a joint plate 92 and a connecting plug plate 93, the connecting plug plate 93 is fixedly connected to the side of the joint plate 92 close to the hollow sleeve plate 91, and the connecting plug plate 93 is plugged into the hollow sleeve plate 91, the two joint plates 92 are movably connected by a pin shaft, and the sides of the two hollow sleeve plates 91 away from each other are movably connected to the top of the base 1 and one side of the T-shaped plate 8 through a hinge seat.

[0021] The front and rear sides of the hollow sleeve 91 are respectively threadedly connected with a hand-tightened bolt 10, and the end of the hand-tightened bolt 10 abuts against the side of the connecting plug plate 93. The hand-tightened bolt 10 can be used to fix the adjustable support plate 9 after the length adjustment is completed to avoid the length from changing arbitrarily and affecting its use. When adjusting the length of the adjustable support plate 9, its purpose is to adjust the connection between the two adjustable support plates 9 to below the knee joint of the patient's leg. The two adjustable support plates 9 support the patient's thigh and calf respectively, which can better assist the patient in bending and straightening his legs.

[0022] The front and rear sides of the hollow sleeve 91 are respectively fixedly connected with an arc-shaped baffle 11, which can block the side of the patient's legs to prevent the patient's legs from falling off the leg support.

[0023] The driving mechanism includes a threaded rod 4 and a reduction motor 5. The threaded rod 4 is movably connected to the inside of the groove 3 through a bearing seat. The reduction motor 5 is fixedly installed inside the groove 3, and one end of the threaded rod 4 and the output shaft of the reduction motor 5 are connected to each other through a coupling. The threaded rod 4 passes through the T-shaped plate 8, and the threaded rod 4 and the T-shaped plate 8 are connected by threads. The driving mechanism can drive the T-shaped plate 8 to move, and the reduction motor 5 in the driving mechanism can be driven in both forward and reverse directions, thereby facilitating the reciprocating movement of the T-shaped plate 8.

[0024] The top of the base 1 is fixedly connected with a cover plate 6 by bolts, and the reduction motor 5 is located below the cover plate 6. The cover plate 6 can cover the reduction motor 5 below to prevent the patient or the patient's clothes from entering the groove 3 and contacting the reduction motor 5, thereby playing a protective role.

[0025] A switch 7 is fixedly installed on the top of the cover plate 6. The reduction motor 5 and the switch 7 are electrically connected. The reduction motor 5 can be controlled to start and stop by the switch 7. As for the forward and reverse control of the reduction motor 5, it is an existing technology and will not be described in detail here.

[0026] Working principle:

[0027] When the patient is undergoing rehabilitation treatment, the patient can sit on the seat 2 and then put his legs on the leg support with the soles of his feet on the side of the T-shaped plate 8. Since the height and leg length of patients are different, the lengths of the two adjustable support plates 9 in the leg support can be adjusted so that the patient's knee joint is located above the connection of the two adjustable support plates 9. When adjusting the length of the adjustable support plate 9, the hand screw bolt 10 can be loosened first. At this time, the connecting plug plate 93 can be extended and retracted inside the hollow sleeve plate 91 to adjust the distance between the joint plate 92 and the hollow sleeve plate 91. After the length is adjusted, the hand screw bolt 10 can be tightened again. The two adjustable support plates 9 respectively support the patient's thigh and calf. The arc-shaped baffle 11 can block the side of the leg to prevent the leg from falling from the adjustable support plate 9. After the above preparations are completed, the reduction motor 5 can be started by the switch 7. The output shaft of the reduction motor 5 drives the threaded rod 4 to rotate. Since the threaded rod 4 and the T-plate 8 are threadedly connected, the T-plate 8 can push the patient's foot to move along the threaded rod 4. During this period, the leg support will also bend from the knee joint when supporting the patient's leg. When the moving position is pushed, the reduction motor 5 will drive the threaded rod 4 in reverse to rotate so that the T-plate 8 moves away from the patient. At this time, the leg support will support the patient's legs and gradually straighten them. This step is repeated to assist the patient's leg rehabilitation treatment.
