Description

Technical Field

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

[0002] Wheelchairs are aids for the mobility and transportation of injured, sick, disabled, or mobility-impaired individuals, playing a vital role in medical care, rehabilitation, and daily life. However, existing wheelchair designs often focus on basic mobility while neglecting 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 prolonged use; the wheelchair's fixings may not be stable enough, making it easy for the injured to slip or get injured during movement; and traditional wheelchairs lack auxiliary functions for rehabilitation training, limiting the injured's range of motion and the effectiveness of the training during the rehabilitation process.

[0003] A typical wheelchair consists primarily of wheels, brakes, a seat, cushion, footrest, backrest, and armrests. However, for critically ill patients, especially those partially unconscious after a cerebral hemorrhage, using one presents numerous safety risks and inconveniences. For example, the seatbelt may not fully secure the patient, making it easy for them to slip downward or forward. Furthermore, the seatbelt can tighten around the patient's chest and abdomen, causing a strong sense of oppression. The lack of leg support means the patient's legs and feet can easily slip off the wheelchair and rub against the ground when turning, potentially causing secondary injuries.

[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 wrapped 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 being fixed. In the long run, it will not only make the patient feel abnormally uncomfortable, but also easily cause excessive pressure on the local epidermis, affecting blood circulation.

[0005] Patent CN111134973A discloses an improved wheelchair, which is provided with two leg safety belts and two shoulder safety belts on the seat part. 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 shoulders and fixed to the safety belt slots on the back of the backrest, thereby achieving the purpose of restraining the patient. However, this solution still uses a belt-like object to fix the patient, which easily makes the patient feel oppressed. In particular, the leg safety belt in this solution is not set reasonably, 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 with 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. By setting up a hand training structure and a leg training structure, auxiliary training of the patient's arms and legs is performed. However, in this solution, a large number of telescopic structures and support 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. 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.

[0009] The objective of the present invention is achieved through the following technical solutions: a rehabilitation wheelchair: comprising a wheelchair frame, a seat cushion, a backrest, handles, moving wheels and auxiliary wheels; the seat cushion and the backrest are provided with an anti-slip mechanism; the anti-slip mechanism comprises a chest and abdomen support vest, a thigh limiting ring and a number of strip-shaped anti-slip support bags; a leg fixing mechanism is provided on the side of the wheelchair frame; a modular support plate is provided on the wheelchair frame; and an auxiliary training component is provided on the modular support plate.

[0010] Furthermore, the chest and abdomen support vest includes a front panel, a back panel and shoulder straps of the vest. The opening of the front panel of the vest is provided with several Velcro strips to connect the two sides. The outer side of the back panel of the vest is provided with a cylindrical three-sided connecting cloth. One side of the three-sided connecting cloth is sewn and connected to the backrest cloth, and one corner of the three-sided connecting cloth is sewn and connected to the back panel of the vest. The shoulder straps of the vest and the front panel of the vest are split design, and the shoulder straps of the vest are connected to the front panel of the vest by buckles. The chest and abdomen support vest is put on the upper body of the user, which can prevent the user from sliding down and being unable to sit steadily due to body weight and control force. The cylindrical three-sided connecting cloth can provide better anti-pulling effect while also reserving a certain amount of movement space, reducing the user's sense of restraint.

[0011] Furthermore, the thigh limiting ring includes a ring belt, the bottom of which is connected to the seat cushion by Velcro, and the ring belt adopts an enlarged universal blood pressure monitor cuff. The ring belt fixes the user's thigh on the seat cushion, which can prevent the user from slipping. The enlarged universal blood pressure monitor cuff is used as the base, and the ventilation tube can be connected to the pressing device so that the air bag inside the universal blood pressure monitor cuff can be inflated and deflated using an air pump, thereby improving the fixation effect on the thigh while maintaining a larger pressure area on the skin, reducing the consequences of poor blood circulation caused by local excessive pressure.

[0012] Furthermore, the material of the strip-shaped anti-slip support bag is thermoplastic polyurethane elastomer, and the bottom of the strip-shaped anti-slip support bag is connected to the seat cushion cloth by sewing. The strip-shaped anti-slip support bag can also use a backpack shoulder pad as a substitute to prevent the user's buttocks from sliding. At the same time, the use of a material such as thermoplastic polyurethane elastomer can reduce long-term pressure on the skin.

[0013] Furthermore, the leg fixing mechanism includes a central axis rod, one end of the central axis rod is provided with two splicing brackets and connected by screws, the two splicing brackets are respectively clamped on both sides of the partial skeleton of the wheelchair skeleton, and the two splicing brackets are connected by screws, the other end of the central axis rod is provided with a circular limit block and connected, the outer side of the central axis rod is provided with a mounting sleeve, the mounting sleeve is rotatably connected to the central axis rod, the mounting sleeve is slidably provided with a mounting ring, the mounting ring and the mounting sleeve are installed with arc-shaped strips, the two arc-shaped strips are connected by a buckle, and the two arc-shaped strips are tied to the user's calf below the knee to prevent the user's feet from slipping off the footrest and rubbing on the ground.

[0014] Furthermore, the modular support plate includes a tray plate, both ends of the tray plate are fixed with lifting ears, and both ends of the bottom of the tray plate are fixed with U-shaped connectors with openings downward, and anti-displacement rings are provided at both ends of the U-shaped connector, and the anti-displacement rings are installed on the round rods of the wheelchair frame, and the U-shaped connector is forked on the round rods of the wheelchair frame. A heating pad is laid on the tray plate, and a USB port is provided on the side of one end of the tray plate, and the USB port is electrically connected to the heating pad. A plastic isolation sheet is laid above the heating pad, and a cylindrical bowl-holding groove is fixed on the top of the tray plate, and the heating pad and the plastic isolation sheet are both penetrated by the cylindrical bowl-holding groove. The inner side of the cylindrical bowl-holding groove is designed as a groove, and a number of anti-slip strips are provided on the groove. The U-shaped connector and the anti-displacement ring cooperate to fix the tray plate to the wheelchair frame. When removing it, it is only necessary to hold the lifting ears and lift it up to a certain height. Compared with various rotating shaft connectors and screw connectors, it can be removed faster, and the structure is simple and stable.

[0015] Furthermore, the auxiliary training component includes a hollow silicone ball, which is placed inside the cylindrical bowl groove and connected by a thin rope. A massage device is provided on one side of the hollow silicone ball. The surface of the massage device is provided with a drum-shaped vibration membrane. The bottom of the massage device is provided with a suction cup connected to the plastic isolation plate. A vibration motor is provided on the side of the massage device. The vibration motor drives the drum-shaped vibration membrane through an eccentric wheel, a bearing and a connecting rod to form a vibration effect. The massage device draws power from the outside. The user places his unconscious palm on the hollow silicone ball and uses the other intact palm to assist in pressing the palm on the hollow silicone ball. When the hollow silicone ball is flattened by force, the palm stretches out, and when the hollow silicone ball is lifted up, the palm bends, thereby completing a palm relaxation training. The drum-shaped vibration membrane adopts a light and thin design, which can reduce the vibration intensity while prolonging the aftershock vibration wave. Placing the palm on the drum-shaped vibration membrane can perform low-intensity and high-frequency vibration massage on the palm.

[0016] Furthermore, the auxiliary training component also includes a support base, a connector is provided above both ends of the support base, metal rods are fixed on both sides of the bottom of the connector, a magnet sleeve is provided on the inner side of the support base at a position relative to the metal rod, the metal rod is inserted into the inner side of the magnet sleeve, a plurality of horizontal bars are provided at the bottom of the support base, a rubber anti-slip strip is embedded at the bottom of the horizontal bar, four pairs of finger sleeves made of elastic cloth are provided on the top of the horizontal bar, and the four pairs of finger sleeves are respectively put on the four fingers from the index finger to the little finger, an inverted L-shaped connecting block is fixed at one end of the support base, one end of the inverted L-shaped connecting block is inserted into the inner side of the lifting ear, and a pressing device is provided between the support base and the connector.

[0018] Furthermore, the replacement components of the pressing device include a massage roller with a plurality of acupoint pressing balls on its surface and a friction roller with a plurality of transverse semi-cylindrical grooves on its surface. The pressing device, the massage roller and both ends of the friction roller are fixed with positioning rods. The massage roller and the positioning rods at both ends of the friction roller are inserted between the support base and the connector and are connected by a rotating shaft. The user places the flexor muscles of the forearm on the friction roller, and as the arm is extended forward, the palm hangs down, and the arm is pulled back and the palm is slightly lifted to complete a muscle stretching training. The massage roller can perform massage and squeezing training on the arm to reduce muscle tension.

[0019] In summary, the present invention has the following advantages compared with the prior art:

[0020] 1. The rehabilitation wheelchair provided in this invention effectively improves the user's sitting stability and reduces the risk of falling due to insufficient body control through the design of the chest and abdomen support vest and thigh limit ring.

[0048] Working Principle: When the present invention is in use, the chest and abdomen support vest is designed specifically for upper body support, effectively preventing unstable sitting posture caused by insufficient body control. The unique tubular three-sided connected fabric not only provides excellent pull-resistant performance, but also cleverly reserves appropriate movement space, greatly reducing the user's sense of restraint. The ring belt design fixes the thighs to the seat cushion fabric, further ensuring the stability of the sitting posture. In particular, an enlarged-sized universal blood pressure monitor cuff is used as the main structure of the ring belt. By connecting the ventilation tube to the compression device and using an air pump to inflate and deflate the air bag inside the cuff, it 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 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 footrest, avoiding the risk of slipping to the ground.

[0049] The clever combination of the U-shaped connector and the anti-displacement ring allows the tray plate to be securely mounted on the wheelchair frame. When disassembly is required, simply lift the lug 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 a hollow silicone ball and use your other healthy hand to assist in pressing. As the silicone ball flattens under pressure, the palm naturally stretches. When the silicone ball returns to its original shape, the palm bends accordingly, completing a comprehensive palm relaxation training. In addition, the lightweight drum-shaped vibration membrane not only reduces vibration intensity but also prolongs the aftershock wave. Simply place your palm on it to enjoy a low-intensity, high-frequency vibration massage to soothe hand muscles.

[0051] For finger straightening and muscle stretching training, place your numb palm on the horizontal bar, insert your fingers into special finger sleeves, and use the pressing device to inflate the airbag, so that the palm slowly presses down to achieve the purpose of finger straightening training. At the same time, place the forearm flexor muscles on the friction roller. As the arm extends and pulls back, the palm drops and slightly lifts, completing a complete muscle stretching training. The design of the massage roller can deeply massage and squeeze the arm, effectively relieving muscle tension and promoting muscle relaxation.

[0052] The embodiments of the present invention are not limited to the above 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 details, and these are all considered to fall within the scope of protection of the present invention.
