Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a hemiplegia side support fixing device and hemiplegia side adjustable support wheelchair. BACKGROUND

[0002] Hemiplegia is also called hemiparesis, which refers to the movement disorder of the same side of upper and lower limbs, facial muscles and lower part of tongue muscles. It is a common symptom of acute cerebrovascular disease. Although the mild hemiplegia patient can still move, when walking, the upper limbs are often flexed and the lower limbs are straightened, and the paralyzed lower limbs draw a semicircle when walking a step. This special walking posture is called hemiplegic gait, so a wheelchair needs to be used in the daily life of the hemiplegia patient.

[0003] When using the traditional wheelchair, the hemiplegia patient sits on the wheelchair, and the hip joint of the patient's lower limbs is in the external rotation state. The patient's upper limbs are directly placed on the armrest of the wheelchair, which leads to the lack of support for the patient's upper limbs, and further causes the sinking of the shoulder joint, resulting in shoulder-hand syndrome or shoulder joint dislocation. In addition, the patient's upper limbs are not fixed, which leads to the uncomfortable sitting posture of the patient and affects the subsequent rehabilitation of the patient.

[0004] After searching, the Chinese patent document CN221205935U discloses a hemiplegia patient wheelchair sitting good limb position pillow, which comprises a support pad, a left binding belt is fixedly assembled at the top of the support pad, a limiting hole is formed in the outer wall of the left binding belt, a magic mother paste binding belt is fixedly assembled on the outer wall of the support pad, and a magic son paste is fixedly assembled on the outer wall of the support pad. The hemiplegia patient wheelchair sitting good limb position pillow is provided with a support pad, which is installed on the armrest of the wheelchair when the patient sits on the wheelchair. The magic mother paste binding belt is connected with the magic son paste through the armrest of the wheelchair, so that the support pad can be fixed on the wheelchair. At this time, the patient can place the arm in the support groove formed in the top of the support pad, and the top of the support pad can support the arm of the patient to a certain extent, avoiding the placement of the patient's arm, and further causing the sinking of the shoulder joint, resulting in shoulder-hand syndrome or shoulder joint dislocation.

[0005] The Chinese patent document CN213218357U discloses a hemiplegic upper limb wheelchair armrest support device, which comprises an L-shaped support plate, an adjusting mechanism, a limiting mechanism and a supporting mechanism. The fixed part of the support plate is provided with an adjusting groove opening downward in the lower half of the side away from the bent part of the support plate, and the center of the adjusting groove is provided with an adjusting mechanism penetrating through the support plate. The bottom of the outer periphery of the adjusting mechanism is fixedly welded with the top of the limiting mechanism, and the inner periphery between the limiting mechanism and the support plate is matched with the outer periphery of the wheelchair armrest. The top of the support plate is provided with two groups of symmetrical supporting mechanisms, and the arms of the patient are placed between the two groups of supporting mechanisms. The side close to the arm of each supporting mechanism and the top of the support plate are both attached with a sponge pad through adhesive. The hemiplegic upper limb wheelchair armrest support device can adapt to different wheelchair armrests and can be adjusted and fixed as needed.

[0006] The Chinese patent document CN211356333U discloses an adjustable anti-spasm support for hemiplegic upper limbs of a wheelchair. The support comprises a first support frame and a second support frame with an arc-shaped cross section. The first support frame is located below the second support frame and is in sliding connection with the second support frame. A telescopic rod is arranged below the first support frame. The upper end of the telescopic rod is hingedly connected to the first support frame by a bolt, and the lower end of the telescopic rod is provided with a buckle for fixing with the wheelchair armrest. The bolt is perpendicular to the axis of the first support frame. An adjusting plate is arranged on the upper surface of one end of the second support frame. The adjusting plate is hingedly connected to the second support frame by a hinge shaft, which is perpendicular to the axis of the second support frame. A vertical screw rod is arranged below the adjusting plate. A turntable is rotatably connected to the upper end of the screw rod. The turntable is in sliding connection with the adjusting plate in a direction perpendicular to the hinge shaft. The lower end of the screw rod penetrates through the second support frame and is threadedly connected to the second support frame.

[0007] During the rehabilitation process, hemiplegic patients need a wheelchair with flexible support position adjustment to assist them in their daily life and rehabilitation training due to insufficient muscle strength and limited body coordination. The existing technology, such as the hemiplegic patient wheelchair sitting and limb position pillow (CN221205935U), the hemiplegic upper limb wheelchair armrest support device (CN213218357U), or the adjustable anti-spasm support for hemiplegic upper limbs (CN211356333U), often lacks sufficient adjustability and adaptability, making it difficult to meet the individual needs of hemiplegic patients. Therefore, it is particularly important to develop a hemiplegic side adjustable support wheelchair that can automatically adjust the support position. Practical new type content

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Embodiment 1

[0030] Referring to Figures 1-4 , a hemiplegia side support fixing device of the present embodiment comprises a support arm 1, the support arm 1 adjusts the height up and down through a motor 2; the end of the support arm 1 is fixed with a support plate 3, the support plate 3 is fixed with a support pad 4, the support pad 4 is provided with a pressure sensor 5; the pressure sensor 5 is electrically connected or wirelessly signal connected with a controller 6, the motor 2 is electrically connected or wirelessly signal connected with the controller 6.

[0031] The pressure sensor 5 can be a plurality of pressure sensors distributed in the support pad.

[0032] The support pad 4 can be selected as a memory foam pad. The memory foam pad is a kind of slow-rebound sponge material made of polyurethane. When the outer wall acts on the memory foam pad, it will be deformed, so that the memory foam pad can well fit the human arm and provide uniform support force. The memory foam pad has certain antibacterial and anti-mite performance and can maintain a certain degree of cleanliness, so it is suitable for use for a long time.

[0033] In order to better fix the arm, as a preferred specific embodiment, one side of the support pad 4 is connected with a magic mother tape binding band 71, and the other side of the support pad is connected with a magic son tape 72. In this way, the arm on the hemiplegic side is further fixed by sticking the magic mother tape binding band to the magic son tape.

[0034] The structure of the support arm 1 for adjusting the height up and down by the motor 2 can be various. As a specific embodiment, the support arm 1 comprises a sleeve 11 and a ball screw, the ball screw is installed in the sleeve 11, and the nut end 12 of the ball screw is fixedly connected with the support plate 3; the screw end 13 of the ball screw is coaxially connected with the output end of the motor 2, for example, a plum blossom coupling can be used for coaxial connection. In this way, more accurate adjustment of the height up and down can be realized. Among them, the motor can be installed in the sleeve to form an integral module.

[0035] Other structures can also be used to realize it. For example, the height up and down can also be adjusted by the way of eccentric wheel, wherein the eccentric wheel is fixedly connected with the output shaft of the motor. The eccentric wheel is a kind of transmission element, and its geometric center and rotation center are not coincident, so when the eccentric wheel rotates, a certain displacement or swing will be generated. By designing the structure of the eccentric wheel and the mounting position of the support arm, the rotary motion can be converted into linear motion, so as to realize the adjustment of the height up and down of the support arm. The motor serves as a power source to provide the torque required for driving the eccentric wheel to rotate.

[0036] As a specific embodiment of the hemiplegic side support fixing device, the working process is as follows:

[0037] When working, the hemiplegic side arm of the hemiplegic patient is placed on the support pad, and the magic mother tape binding band is further bound, the pressure sensor on the support pad monitors the support pressure on the arm in real time,

[0038] The controller is responsible for receiving the signal from the pressure sensor and controlling the operation of the motor according to the preset pressure value range, so as to drive the motor to rotate and drive the support arm to be at the height up and down in the appropriate pressure range, so that the pressure value is in the pressure value range preset by the controller, thereby realizing the automatic adjustment of the position of the support arm and providing the technical effect of stable and suitable support.

[0039] It should be noted that the pressure sensor and the controller can be connected by wire (i.e. electrical connection) or wirelessly (i.e. wireless signal connection). When it is wirelessly connected, a wireless pressure sensor can be used, which is composed of a pressure sensor module and a wireless communication module. The pressure sensor module is responsible for measuring the pressure signal and converting it into an electrical signal, while the wireless communication module is responsible for transmitting the measured pressure information to the controller wirelessly.

[0040] Similarly, the controller can also wirelessly control the motor. The principle of wireless control of the motor is to send a wireless signal to control the start-stop and running direction of the motor. Embodiment 2
