Description

Technical Field

[0001] The invention relates to a wheelchair for rehabilitation, belonging to the technical field of wheelchairs specially suitable for patients or disabled people or special transportation tools. Background Art

[0002] Wheelchairs are auxiliary tools for the movement and transportation of the wounded, sick, disabled or mobility-impaired, and they play a vital role in medical treatment, rehabilitation and daily life. However, existing wheelchair designs often focus on basic mobility functions while ignoring the comfort, safety and rehabilitation needs of the injured. For example, the seat cushions and backrests of many wheelchairs are made of hard materials, which can cause discomfort to the injured after long-term use; the wheelchair's fixing device may not be stable enough, which can easily cause the injured to slip or get injured during movement; in addition, traditional wheelchairs lack auxiliary functions for the rehabilitation training of the injured, which limits the range of motion and training effect of the injured during the rehabilitation process.

[0003] Common wheelchairs are mainly composed of wheels, brakes, seats, cushions, footrests, backrests and armrests. However, for critically ill patients, especially those who are partially unconscious after cerebral hemorrhage, there are many safety hazards and inconveniences in using them. For example, the safety belt cannot completely fix the patient, and the patient is easy to slip down and forward. At the same time, there is also the disadvantage that the safety belt tightens the patient's chest and abdomen, causing a strong sense of oppression; there is a lack of leg support, and when the wheelchair turns, the patient's unconscious legs and feet are easy to slip off the wheelchair and rub against the ground, which may cause secondary injuries in severe cases.

[0004] Patent CN207898601U discloses a waist and leg wheelchair restraint belt, which is fixed to the wheelchair seat by a pad and a belt body. After the patient's waist is fixed by an elastic belt, the leg restraint belts on both sides are respectively passed around the patient's thighs and fixed by Velcro, so as to achieve the purpose of restraining the patient in the wheelchair. However, the belt used to restrain the patient in this scheme will still press on the patient's chest, abdomen and legs after fixation. In the long run, it will not only make the patient feel abnormally uncomfortable, but also easily cause the local epidermal pressure to be too strong, affecting the blood circulation.

[0005] Patent CN111134973A discloses an improved wheelchair, which achieves the purpose of restraining the patient by arranging two leg safety belts and two shoulder safety belts at the seat part, wherein one end of the leg safety belt is connected to the seat cushion, and the other end is connected to the safety belt slots on the left and right sides through the safety belt buckle, one end of the shoulder safety belt is fixed to the front of the backrest, and the other end is passed around the patient's shoulder and fixed to the safety belt slots on the back of the backrest, thereby achieving the purpose of restraining the patient. However, this scheme still exists the situation of using belts to fix the patient, which easily makes the patient feel oppressed, especially the leg safety belt in this scheme is not reasonably arranged, and when the patient slides down slightly, it will produce huge tightening pressure on the crotch.

[0006] Moreover, none of the above solutions has redundant moving space, and the patient cannot maintain a sitting posture all the time, which will have additional negative effects on him. In addition, conventional wheelchair dining tables are usually fixed to the wheelchair frame by brackets and shafts, but this also makes it easy to flip and difficult to disassemble. The huge size makes it still lack a good accommodation effect after flipping and folding.

[0007] Patent CN113768703A discloses an intelligent wheelchair based on flexible impedance training, which assists the patient's arms and legs in training by setting up a hand training structure and a leg training structure. However, in this solution, a large number of telescopic structures and supporting structures are set up, making the overall structure extremely bloated and inconvenient to store. In addition, both training structures use strong external forces to stimulate the patient's torso movement, and patients who are still sitting in a wheelchair find it difficult to adapt to this high-intensity training, which can easily cause muscle tissue damage. Summary of the invention

[0008] In view of the defects existing in the above-mentioned prior art, the present invention provides a rehabilitation wheelchair to solve the problems that common wheelchairs lack an effective and comfortable fixing structure for patients, the dining table board is large and difficult to store, and the auxiliary training structure has poor applicability.

[0048] Working principle: When the scheme of the present invention is in use, the chest and abdomen support vest set is specially designed for upper body support, which effectively prevents unstable sitting posture caused by insufficient body control. The unique cylindrical three-side connected fabric not only provides excellent anti-pulling performance, but also cleverly reserves a moderate activity space, which greatly reduces the user's sense of restraint. The ring belt design fixes the thigh on the cushion cloth, further ensuring the stability of the sitting posture. In particular, an enlarged size of the universal cuff of the blood pressure monitor is used as the main structure of the ring belt. By connecting the ventilation tube to the pressing device, the air pump is used to inflate and deflate the air bag inside the cuff, which not only strengthens the fixation effect of the thigh, but also effectively avoids blood circulation disorders caused by excessive local pressure by increasing the pressure distribution area. In addition, the addition of the anti-slip support bag not only effectively prevents the buttocks from sliding, but also its selected thermoplastic polyurethane elastomer material greatly reduces the long-term pressure on the skin. The two arc-shaped strips below the knee are tied to the calf to ensure that the user's feet are firmly fixed on the pedals, avoiding the risk of sliding off the ground.

[0049] The clever combination of the U-shaped connector and the anti-displacement ring allows the tray plate to be firmly installed on the wheelchair frame. When it needs to be disassembled, you only need to easily lift the lifting ear to a certain height. Compared with complex shaft and screw connectors, this design is not only more convenient to operate, but also more stable and reliable in structure.

[0050] A new training method is provided for palm function recovery: place the insensitive palm on the hollow silicone ball, and use another healthy palm to assist in pressing. As the silicone ball becomes flat under pressure, the palm naturally stretches, and when the silicone ball returns to its original shape, the palm bends accordingly, thus completing a comprehensive palm relaxation training. In addition, the thin and light drum-shaped vibration membrane not only reduces the vibration intensity, but also prolongs the aftershock wave. Just place your palm lightly on it to enjoy a low-intensity, high-frequency vibration massage to soothe your hand muscles.

[0051] For finger straightening and muscle stretching training, place the numb palm on the horizontal bar, insert the fingers into the special finger sleeve, inflate the airbag through the pressing device, and slowly press the palm downward to achieve the purpose of training finger straightening. At the same time, place the forearm flexor muscles on the friction roller. As the arm extends forward and pulls back, the palm drops and slightly lifts to complete a complete muscle stretching training. The design of the massage roller can deeply massage and squeeze the arm, effectively relieve muscle tension and promote muscle relaxation.

[0052] The implementation of the present invention is not limited to the above-mentioned embodiments. Without departing from the spirit and scope of the present invention, ordinary technicians in this field can make various changes and improvements to the present invention in form and detail, and these are considered to fall within the protection scope of the present invention.
