Description

Technical Field

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

[0002] During the treatment of neurosurgery patients, in order to avoid muscle atrophy caused by long-term bed rest, patients need to undergo corresponding rehabilitation training and nursing operations regularly. Taking lower limb rehabilitation training as an example, after long-term bed rest, the muscles of both legs of patients will atrophy. In the subsequent rehabilitation process, if patients need to stand or walk, muscle atrophy will increase the pressure on the knee and hip joints, causing the patients to be unable to maintain balance when standing, and thus have difficulty walking independently.

[0003] In response to this type of situation, in clinical nursing, medical staff and patients' families need to use their hands to pull the patients' legs to assist them in completing flexion and extension exercises. After the patients are familiar with the movements of leg flexion and extension exercises, they can then perform leg flexion and extension exercises independently to promote muscle recovery and health. However, in actual operations, when medical staff and patients' families use their hands to pull the patients' legs, as time goes by, they will consume a lot of physical energy and their hands will feel sore, making it difficult for them to continue to perform stable pulling movements on the patients' legs. As a result, the patients' leg flexion and extension exercises will be irregular or inadequate, which will not only increase the workload of medical staff and patients' families, but also prolong the time it takes for patients to adapt to leg flexion and extension exercises, and result in the inability of patients' lower limbs to receive effective rehabilitation training.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] The embodiment of the utility model provides a limb rehabilitation training device, including a base plate 1 and a leg flexion and extension auxiliary device 2, the base plate 1 is a rectangular parallelepiped as a whole, and a plurality of supporting legs that can support the base plate 1 are arranged at the bottom of the base plate 1, a seat 3 with a backrest angle adjustment function is arranged on the base plate 1, the leg flexion and extension auxiliary device 2 is located on the front side of the seat 3, and the leg flexion and extension auxiliary device 2 is composed of a push plate 21 and two foot pedals 22, the push plate 21 is horizontally placed on the base plate 1, that is, the left and right ends of the push plate 21 correspond to the two longer sides of the base plate 1, and the two foot pedals 22 are symmetrically arranged on the push plate 21;

[0026] A driving device 4 is provided below the base plate 1, which can drive the push plate 21 to reciprocate toward the seat 3 and the front side of the base plate 1. The driving device 4 is provided with a matching controller. The driving device 4 can be a device with a linear driving function such as a slide cylinder. A through groove 11 is provided at a corresponding position of the driving device 4 on the base plate 1, and the length of the through groove 11 is adapted to the driving stroke of the driving device 4. The output end of the driving device 4 passes through the through groove 11 and is fixedly connected to the bottom of the push plate 21. The two ends of the push plate 21 are in sliding cooperation with the base plate 1.

[0027] When in use, the patient needs to sit on the seat 3 and place both feet on the two foot pedals 22 on the push plate 21, and then operate the controller according to the lower limb rehabilitation situation. The controller can be used to set the moving speed of the output end of the driving device 4 and the interval time of the reciprocating movement accordingly;

[0028] When the patient is doing the initial training, take the end of the push plate 21 on the through slot 11 of the bottom plate 1 away from the seat 3 as the initial position as an example. When the patient sits on the seat 3 and puts both feet on the two foot pedals 22, the lower limbs are in an extended state. During the operation of the driving device 4, its output end will apply driving force to the push plate 21 from below the through slot 11 on the bottom plate 1, and drive the push plate 21 to move slowly toward the seat 3. As the push plate 21 starts to operate, the two foot pedals 22 will simultaneously apply thrust to the patient's feet, and prompt the patient's knees to gradually move up. Bending, the patient's knees will assist the patient's ligaments and muscle tissues of the calf, knee joint, thigh and hip to exercise during the bending process. When the position of the push plate 21 on the through slot 11 is close to the seat 3, the driving device 4 can be suspended and the push plate 21 can be controlled to remain stationary. At this time, the patient's legs will maintain the knee bending state under the pushing action of the two foot pedals 22 and the push plate 21, so that the patient's knee joints can be in a bent state, and their muscle tissues and ligaments can adapt to the corresponding state and play a relieving role;

[0029] Then the driving device 4 can drive the pushing plate 21 to move away from the seat 3, that is, the pushing plate 21 returns to the initial position. During the movement of the pushing plate 21, the two foot pedals 22 can guide the patient's legs and drive the patient's knee joints to gradually stretch from the original bent state, so that the ligaments, joints and muscle tissues of the patient's legs can be stretched. When the position of the pushing plate 21 on the through groove 11 is away from the seat 3, the driving device 4 can be suspended again and the pushing plate 21 can be controlled to remain stationary, so that the patient's legs can maintain a straight state for a certain period of time, thereby helping the muscle tissues and ligaments of the patient's legs to adapt to the corresponding state.

[0030] In this reciprocating manner, when the driving device 4 drives the pushing plate 21 and the two foot pedals 22 to move back and forth, the patient's legs will be intermittently flexed and extended, and the rehabilitation training of the leg muscle tissue and toughness will be promoted.

[0031] In a further preferred embodiment, the middle portion of each footrest 22 is bent, and the rear half of each footrest 22 is in a horizontal state, that is, the half portion of each footrest 22 close to the seat 3 is in a horizontal state, and the front half portion of each footrest 22 is bent from its middle portion and extends to the upper front area of ​​the base plate 1, and the angle formed between the front half portion and the rear half portion of each footrest 22 is greater than 90 degrees, and the angle portion formed by the combination of the front half portion and the rear half portion of each footrest 22 can be placed on the patient's heel, and the front half portion of the footrest 22 is bent from its middle portion and extends to the upper front area of ​​the base plate 1 to form an inclined shape for placement on the sole of the patient's foot;

[0032] Among them, the front half of each foot pedal 22 can also be used to place the patient's toes, and the sole of the foot close to the toes can be placed on the corresponding rear half of the foot pedal 22, so that the entire foot is placed in a tiptoe-like state, and then when the push plate 21 moves toward the seat 3, the foot pedal 22 can apply pressure to the toe joints of the patient's sole to promote blood circulation in the sole.
