Description

Technical Field

[0001] This utility model relates to the field of limb rehabilitation training technology, specifically a limb rehabilitation training device for nursing. Background Technology

[0002] Arthritis is a chronic systemic disease of unknown cause. Common symptoms include inflammation of the small joints of the hands and feet, accompanied by pain. In severe cases, it can lead to joint deformities and loss of function. This disease is not easily treated surgically, and symptoms are usually relieved through rehabilitation exercises and medication.

[0003] For example, a rheumatoid arthritis lower limb rehabilitation exercise device with authorization announcement number CN216366514U uses a threaded tube connected to a threaded rod on a suction cup at one end of an elastic tension band. This allows the suction cup to adhere to the bottom surface, and the threaded tube to adjust the tension. The patient sits on a chair with their feet passing through the loops of the elastic tension band to perform leg-raising rehabilitation exercises. This device is small, simple in structure, easy to use, and inexpensive, making it convenient for patients to perform rehabilitation exercises at home. However, the existing elastic band in the limb rehabilitation training device described in the above document has a relatively uniform elasticity and cannot be adjusted to suit different patients' conditions, thus failing to meet the needs of different patients.

The axial length of the connecting groove is the same as the axial length of the circular hole, and the radial cross-sectional shape and size of the connecting groove are exactly the same as the radial interface size of the positioning groove.

[0011] The outer ring surface of one side of the card holder is provided with two sets of threaded holes, and the threaded holes on both sides are symmetrically mirrored.

[0012] Preferably, the inner diameter of the cavity is the same as the outer diameter of the disc, the cavity can match the disc, and a spring is provided between the cavity and the disc.

[0013] Preferably, the elastic band is provided with connecting posts at both ends, and the outer ends of the connecting posts are provided with two sets of locking blocks, and the two sets of locking blocks are symmetrically and mirror-distributed.

[0014] Preferably, the radial cross-sectional dimension of the card block is the same as the radial cross-sectional dimension of the positioning groove and the connecting groove, and the axial length of the card block is the same as the axial length of the positioning groove.

Before the connecting column enters the cavity, a locking block aligns with a connecting groove, allowing the locking block to follow the connecting column into the cavity. Simultaneously, the connecting column moves a circular plate, which in turn compresses a spring. Rotating the connecting column then aligns the locking block with the positioning groove. The connecting column then causes the locking blocks on both sides to match the positioning groove. At this point, the spring force prevents the circular plate from limiting the connecting column, thus adding an elastic band to the locking seat. Similarly, the connecting column causes the locking block to separate from the positioning groove. Rotating the connecting column again aligns the locking block with the connecting groove, separating the connecting column from the cavity and disassembling the elastic band, thereby meeting the training intensity requirements of different patients' limbs.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] See attached document Figure 1-5This utility model proposes a limb rehabilitation training device for nursing care, including a snap-fit ​​assembly 1 and an elastic band 4. The snap-fit ​​assemblies 1 are respectively arranged on both sides of the elastic band 4, and the snap-fit ​​assemblies 1 on both sides are arranged symmetrically and mirror images. The snap-fit ​​assembly 1 includes a snap-fit ​​seat 101, a spring 102 and a disc 103. The snap-fit ​​seat 101 is provided with a plurality of springs 102 and discs 103 inside, and the number of springs 102 is the same as the number of discs 103. The two ends of the springs 102 are fixedly connected to the snap-fit ​​seat 101 and the discs 103 respectively.

[0028] The snap-fit ​​base 101 has multiple circular cavities 1011 in its center, with the axis of one of the cavities 1011 aligned with the axis of the snap-fit ​​base 101. The remaining cavities 1011 are arranged in a ring array around the axis of the snap-fit ​​base 101. A circular hole 1012 is provided on the side of each cavity 1011 adjacent to the elastic band 4. The axis of the circular hole 1012 is aligned with the axis of the cavity 1011 and penetrates the snap-fit ​​base 101. The inner annular surface of the circular hole 1012 is respectively provided with… It has two sets of positioning grooves 1014 and connecting grooves 1013, and the two sets of positioning grooves 1014 are symmetrically arranged, and the two sets of connecting grooves 1013 are symmetrically mirrored. The axial length of the connecting groove 1013 is the same as the axial length of the circular hole 1012. The radial cross-sectional shape and size of the connecting groove 1013 are exactly the same as the radial interface size of the positioning groove 1014. Two sets of threaded holes 1015 are provided on the outer ring surface of one side of the snap-fit ​​seat 101, and the threaded holes 1015 on both sides are symmetrically mirrored.

[0029] The inner diameter of the cavity 1011 is the same as the outer diameter of the disc 103. The cavity 1011 can match the disc 103, and the disc 103 can slide along the cavity 1011. The disc 103 can drive the spring 102 to deform. A spring 102 is provided between the cavity 1011 and the disc 103. Connecting posts 401 are provided at both ends of the elastic band 4. Two sets of locking blocks 402 are provided at the outer ends of the connecting posts 401, and the two sets of locking blocks 402 are symmetrically and mirror-distributed. The connecting posts 401 penetrate into the cavity 1011 through the circular hole 1012. At the same time, before the connecting posts 401 enter the cavity 1011, the locking blocks 402 will correspond to the connecting grooves 1013, so that the locking blocks 402 will follow the connecting posts. 401 enters the interior of the circular cavity 1011. At the same time, the connecting post 401 drives the circular piece 103 to move. The circular piece 103 drives the spring 102 to compress. Then, the connecting post 401 is rotated so that the locking block 402 corresponds to the position of the positioning groove 10. The connecting post 401 drives the locking blocks 402 on both sides to match the positioning groove 1014. At this time, the elastic force of the spring 102 causes the circular piece 103 to be unable to limit the connecting post 401, so that the elastic band 4 is added to the locking seat 101. Similarly, the connecting post 401 drives the locking block 402 to separate from the positioning groove 1014. Rotating the connecting post 401 makes the locking block 402 correspond to the connecting groove 103, separating the connecting post 401 from the circular cavity 1011, so as to disassemble the elastic band 4.

[0030] The radial cross-sectional dimensions of the locking block 402 are the same as those of the positioning groove 1014 and the connecting groove 1013, and the axial length of the locking block 402 is the same as that of the positioning groove 1014. The threaded hole 1015 is threadedly connected to one side of the handle 3. The outer wall of the handle 3 is provided with sponge to reduce the hard contact between the handle 3 and the patient, thereby increasing the patient's comfort.

[0031] One end of the snap-fit ​​seat 101 away from the elastic band 4 is provided with a connecting strap 2. The connecting strap 2 is used to slip on the patient's limb to facilitate exercise. The other end of the snap-fit ​​seat 101 away from the elastic band 4 is provided with a fixing component 5. The fixing component 5 includes a fixing plate 501, guide posts 502, a connecting seat 503, a screw 504, a circular plate 505, and a rubber pad 506. The outer wall of the circular plate 505 is textured to increase the friction between the user's hand and the circular plate 505, making it easier for the user to rotate the circular plate 505. The circular plate 505 drives the screw 504 to move, and the screw 504 drives the fixing plate 501 to move away from the connecting seat 503. The fixing plate 501 drives the guide posts 502 on both sides to move. The guide posts 502 move along the sliding holes 5031. At the same time, the screw 504 stretches along the rubber pad 506, so that a negative pressure cavity is formed between the rubber pad 506 and the ground, thereby fixing the connecting seat 503 to the ground. By rotating the circular plate 505, The fixing plate 501 moves toward the adjacent connecting seat 503, and is clamped by the connecting seat 503 and the fixing plate 501, achieving different fixing methods. This makes it convenient for the training equipment to be clamped at the foot of the bed for patients to train while lying down. One end of the fixing plate 501 is fixedly connected to the snap-fit ​​seat 101 on the side away from the connecting belt 2. Guide posts 502 are respectively provided on both sides of the fixing plate 501. The middle part of the fixing plate 501 is fixedly connected to the screw 504. The outer wall of the screw 504 is threadedly connected to the circular plate 505. The end of the screw 504 away from the fixing plate 501 is fixedly connected to the rubber pad 506. The end of the rubber pad 506 adjacent to the screw 504 is fixedly connected to the connecting seat 503. The middle part of the connecting seat 503 is rotatably connected to the circular plate 505. Sliding holes 5301 are respectively provided on both sides of the connecting seat 503. The inner diameter of the sliding hole 5301 is the same as the outer diameter of the guide post 502, and the guide post 502 can match the sliding hole 5301.

[0032] Specifically, during use, an appropriate number of elastic bands 4 are added according to the patient's joint recovery and individual condition. The connecting post 401 extends into the cavity 1011 through the round hole 1012. Before the connecting post 401 enters the cavity 1011, the locking block 402 corresponds to the connecting groove 1013, so that the locking block 402 follows the connecting post 401 into the cavity 1011. At the same time, the connecting post 401 drives the disc 103 to move, and the disc 103 drives the spring 102 to compress. Then, the connecting post 401 is rotated so that the locking block 402 engages with the fixed groove. The position of the slot 10 corresponds to the position of the connecting column 401, which drives the two side blocks 402 to match the positioning slot 1014. At this time, the elastic force of the spring 102 causes the disc 103 to be unable to limit the connecting column 401, thus realizing the addition of the elastic band 4 to the card seat 101. Similarly, the connecting column 401 drives the block 402 to separate from the positioning slot 1014. Rotating the connecting column 401 makes the block 402 correspond to the connecting slot 103, separating the connecting column 401 from the cavity 1011, thus realizing the disassembly of the elastic band 4, thereby meeting the training intensity of different patients' limbs.

[0033] The operator rotates the circular plate 505, which drives the screw 504 to move. The screw 504 drives the fixing plate 501 to move away from the connecting seat 503. The fixing plate 501 drives the guide columns 502 on both sides to move. The guide columns 502 move along the sliding hole 5031. At the same time, the screw 504 stretches along the rubber pad 506, so that a negative pressure cavity is formed between the rubber pad 506 and the ground, thus fixing the connecting seat 503 to the ground. By rotating the circular plate 505, the fixing plate 501 moves towards the adjacent connecting seat 503. The connecting seat 503 and the fixing plate 501 achieve clamping, realizing different ways of fixing. It is convenient for the training equipment to be clamped at the foot of the bed so that the patient can train while lying down. By attaching the two sets of connecting straps to the patient's limbs, the limbs are stretched to exert force. By gripping the handle 3, both limbs can be trained at the same time.
