Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a rehabilitation device for stroke patients with the function of maintaining a good limb position. Background Art

[0002] Stroke is characterized by high morbidity, high mortality, high disability rate and high recurrence rate, which brings heavy economic and social burden to families and society. Hemiplegia is the most common sequela of stroke patients. According to statistics, there are 2 million new stroke patients in China every year, of which about 70%-80% of patients still have limb dysfunction after treatment. Incorrect supine posture can cause joint contracture of patients, induce and aggravate limb spasm, cause shoulder dislocation, cause shoulder-hand syndrome, and aggravate functional impairment of patients, which is not conducive to the rehabilitation of affected limbs. Correct limb positioning can also maintain good blood circulation and prevent pressure sores. Early good limb positioning can protect joints and surrounding soft tissues. In the later rehabilitation treatment, the pain of patients during passive activities is reduced, and they can enter the role of rehabilitation treatment more quickly, and their resistance to rehabilitation is reduced, thereby reducing the disability rate to varying degrees, improving the quality of life of patients, reducing a certain economic and care burden for patients' families and society, and creating conditions for patients to rebuild their confidence and return to society as soon as possible. In clinical practice, due to various reasons, such as the cognition and cooperation of patients and their families, it is difficult to properly position the limbs.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1

[0026] The present invention discloses a rehabilitation device for stroke patients with a good limb position maintaining function, comprising: a box 10, a headrest 1, a center pad 19, a back pad assembly, an arm pad assembly, a leg pad assembly, a knee pad assembly, a filling structure 18, a cylinder and a transmission assembly 12; the headrest 1, the center pad 19, the back pad assembly, the arm pad assembly, the leg pad assembly, the knee pad assembly, and the filling structure 19 are fixed to the upper part of the box 10, the cylinder and the transmission assembly are fixed to the inside of the box 10, the headrest 1 is fixed to the top of the box 10, and the center pad 19 is fixed to the center of the lower side of the headrest 1.

[0027] Example 2

[0028] In this embodiment, the back pad assembly includes a left back pad 5 and a right back pad 4, which are movably installed on both sides of the center pad 19. One side of the back pad assembly is a soft bag tissue, and the other side is a metal structure. One side of the metal structure is provided with a rotating shaft support and a connecting rod. The rotating shaft support is fixed to the two ends of the back pad and is hinged to the cylinder and the cylinder connector 12. The connecting rod is fixed to the middle and top of the back pad and is hinged to the box rotating shaft support. There is a guide rod structure 14 on the connecting rod that is connected to the arm pad assembly. An inclined groove is opened on one side of the metal structure to avoid other components. The left and right back pad assemblies are each connected to a cylinder. According to the requirements of the affected side lying position in the good limb position, the patient needs to turn over to one side to increase the stimulation felt by the affected limb, reduce spasms, and enable the healthy limb to move freely. Therefore, the back pads 4, 5 and leg pads 6, 7 can be rotated a certain angle with the center pad 19 as the rotation center under the push of the cylinder to assist the patient in turning over.

[0029] Example 3

[0030] In this embodiment, the arm pad assembly is divided into a left arm pad assembly and a right arm pad assembly, which are respectively installed on both sides of the center pad. The left arm pad assembly consists of a left arm pad upper assembly 3 and a left arm pad lower assembly 11. The right arm pad assembly consists of a right arm pad upper assembly 2 and a right arm pad lower assembly 17. The arm pad upper assembly is a soft bag tissue with a massage function structure inside the soft bag tissue. One end of the arm pad upper assembly 2 and 3 is a right-angled side with side baffles on both sides. The other end of the arm pad upper assembly 2 and 3 is semicircular, and the lower part of the end has a shaft hole for rotationally connecting with the arm pad lower assembly 17 and 11. The arm pad lower assembly 17 and 11 are metal structures with upper surfaces. There is a rotating shaft that cooperates with the upper component of the arm pad, a scissor-shaped connecting rod structure 13 is provided on the lower surface, and two slide grooves are provided on the inner side. Each slide groove is slidably matched with a rotating shaft seat, and the rotating shaft seat is fixedly installed on the other side of the slide groove. Another scissor connecting rod mechanism and a slider connecting rod mechanism 14 are provided at the lower end of the structure to connect with the back pad component. In order to reduce the pressure on the shoulder joint, prevent the shoulder joint from being dislocated, promote blood circulation, prevent muscle atrophy and promote rehabilitation when the patient is lying on the affected side or the healthy side, a pillow is often placed under the lower arm after the patient turns over. The arm pad of the device can be automatically raised under the linkage of the rotation of the back pad to replace manual pillow placement under the patient's arm, for example Figure 3 , Figure 5 As shown, when the left back pad 5 and the left leg pad 7 are turned over by the cylinder, the right arm pad upper component 2 and the right arm pad lower component 17 can be raised at the same time through the driving of the linkage mechanism. In addition, according to the different needs of placing the arm at different angles, Figure 3 As shown, the right arm pad component 2 can be rotated relative to the arm pad component 17 to serve as an arm support. There is a massage mechanism inside the arm pad component 2, which can massage the affected limb to improve blood circulation, relieve muscle spasms and pain, and promote the recovery of limb function.

[0031] Example 4

[0032] In this embodiment, the leg pad assembly is divided into a left leg pad assembly 7 and a right leg pad assembly 6, which are respectively installed on both sides of the center pad 19. The leg pad assembly is fixedly installed on the lower side of the back pad and can rotate under the drive of the side back pad. Figure 3As shown, the flipping of the left back pad 5 can drive the left leg pad 7 to flip at the same time to assist the patient to turn over. There is a notch at the lower end of the leg pad assembly to store the knee support pad inside; the knee pad assembly is divided into a left knee pad 9 and a right knee pad 8, which includes a knee support pad and a linkage mechanism. The knee support pad is a soft bag tissue, which is stored between the grooves of the leg pad assembly and fixedly connected to the linkage mechanism. The linkage mechanism includes a parallelogram linkage mechanism 15 and a guide rod mechanism 16; in the affected side lying position and the healthy side lying position, in order to reduce the muscle spasm of the affected lower limb, improve the blood circulation of the lower limb, reduce the pressure on the hip joint and knee joint, maintain the joint mobility, and prevent joint stiffness and contracture, the upper leg after lying on the side often needs to bend the knee. Regardless of whether it is the affected side lying position or the healthy side lying position, the caregiver needs to help the patient perform a knee flexion operation. In order to solve the problem that some caregivers are unable to complete this operation for the patient, the device is provided with an auxiliary knee flexion device without the need for other active parts, such as Figure 3 , Figure 5 , Figure 6 As shown, the rotation of the left leg pad 7 can be linked with the guide rod mechanism 16 through the parallelogram mechanism 15, so that the left knee pad 9 is raised to assist the patient in bending the knee. After turning over, the leg with the bent knee can fall on the other leg.

[0033] Example 5

[0034] In this embodiment, the filling structure 18 is a soft-packed elastic tissue, which is fixedly installed in the gap between the center pad 19 and the back pad assembly and the leg pad assembly. While ensuring that the mechanism linkage can operate normally and the various components do not interfere with each other, it protects the patient from being clamped by the flipping mechanism, and at the same time provides support for the patient's back to ensure the patient's comfort; the headrest 1 is a soft-packed tissue with side baffles on the outside, which is higher than other cushions, conforms to ergonomics, does not require other pillows, and can ensure that the patient still has a good pillow posture after the flipping action.

[0035] Example 6

[0036] The device can meet the needs of different patients with different diseased sides, and can be turned to the left or right. Figure 7 To turn over to the left side, the left arm pad will rise, the right back pad and leg pad will rotate, and the right knee pad will rise, and vice versa. In addition, as the rehabilitation process progresses, the user of the device can gradually transition to self-adjustment of body position and enhance self-care ability. According to previous practice, it is recommended to change body position every 2 hours.

[0037] Example 7

[0038] In this embodiment, the device is provided with a plurality of emergency stop buttons, which are convenient for caregivers and patients to use in time, so as to immediately cut off the power supply and stop the operation of the device in case of emergency.

[0039] Example 8

[0040] The present invention discloses a rehabilitation device for stroke patients with a good limb position maintaining function, and the specific working principle and process are as follows:

[0041] Before using the device, a professional medical staff is required to conduct an assessment to determine the patient's appropriate body position and support requirements. After the patient lies flat on his back, the patient is placed in the affected side position. After the caregiver or patient chooses to turn over to the left or right side, press the control switch on that side. For example, if the patient turns over to the right side, Figure 3 , Figure 5 , Figure 6 The cylinder starts to slowly push the left back pad 5, and the left back pad 5 drives the left leg pad 7 to flip, so as to push the patient to flip to the right side. During the flip, the right arm pad upper component 2 and the right arm pad lower component 17 slowly rise through the linkage of the guide rod mechanism 14 and the scissor-shaped connecting rod 13, so that the patient's right arm is lifted up. At the same time, the left knee pad 9 rises at the same time under the linkage of the parallelogram connecting rod 15 and the guide rod mechanism 16, so as to assist the patient to bend his knees. In addition, with the assistance of gravity, the patient's knee will fall on the other leg after being bent. When the patient has completed turning over, the cylinder is retracted and the device returns to its original position. At this time, the caregiver can fine-tune the patient's posture. The caregiver can turn the right arm pad upper component 2 to adjust the patient's arm to a comfortable position. In addition, the massage function of the arm pad upper component 2 can be turned on as needed to promote blood circulation in the affected limb. At this point, the complete working process of the device is completed. In addition, the structure and function of turning over on the left side and turning over on the right side are basically the same, and can be used according to the needs of the patient.

[0042] In summary, the present invention, driven by the cylinder, completes the work of assisting patients and caregivers to place patients in optimal limb positions through a series of connecting rod mechanisms, replacing caregivers' help for patients to put pillows under their arms, helping patients to turn over to one side, helping patients to bend their knees and other actions that patients cannot complete independently, thereby reducing the work intensity and pressure of caregivers, while also increasing the frequency of position changes, helping to prevent pressure sores and promoting blood circulation. In addition, the device only needs one pneumatic component each to complete turning over to the left and turning over to the right, thereby reducing the cost of drive components, the difficulty of control, and the time and cost of maintenance and repair.

[0043] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only the specific implementation methods described.
