Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a leg burn rehabilitation training device. Background Art

[0002] Burn patients need to perform functional exercises during their postoperative rehabilitation period, mainly to prevent or alleviate contracture deformities after burn healing, and also to help restore limb muscle strength, improve blood circulation, and facilitate wound repair. Functional exercise methods mainly include passive and active movements. Passive movement relies on massage, manipulation, traction, and other methods from others to restore a certain degree of joint mobility, creating a relatively relaxed environment for active movement. Active movement is a method for patients to move themselves after their condition stabilizes. Active movement can increase physical strength and improve cardiopulmonary function. Existing leg rehabilitation training devices have a single training method and are not easy to adjust.

[0003] Patent application number CN202220101405.4 discloses a leg exercise rehabilitation device for burn patients, comprising a mounting plate and a leg exerciser mounted on the mounting plate. The leg exerciser includes a support frame and a foot damping assembly mounted on top of the support frame. The support frame comprises two parallel mounting tubes and a support tube connected between the middle portions of the two mounting tubes. The support tube is a bent structure with its opening facing downward. The foot damping assembly includes a connecting tube, a crankshaft rotatably mounted within the connecting tube, and a damping adjustment bolt radially threaded into the connecting tube. The end face of the damping adjustment bolt abuts against the outer wall of the crankshaft. Foot pedals are rotatably connected to both ends of the crankshaft. The connecting tube is arranged parallel to the mounting tube, with the middle portion of the connecting tube fixedly connected to the middle portion of the top of the support tube. The mounting tube is adjustably mounted on the mounting plate via a guide tube, which is arranged parallel to the mounting plate surface. However, this patent still fails to implement various leg training methods, such as flexion and extension, straightening, opening, and closing. Summary of the Invention

[0004] The purpose of the present invention is to provide a leg burn rehabilitation training device, which solves the problem that existing leg burn rehabilitation training equipment is difficult to achieve the training functions of flexion, extension, opening and closing of the legs through the functions of movable legs, leg support components and pedals.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention relates to a leg burn rehabilitation training device, comprising a support frame for supporting the weight of a patient and the device, a seat cushion for the patient to sit on fixedly installed on the top of the support frame; a back cushion for leaning on the back of the seat cushion is installed at an angle; there are two movable legs, which are symmetrically rotated and arranged under the seat cushion; a grip rod for manually assisting the horizontal rotation of the movable legs is fixed on the top of the movable legs near the seat cushion; a leg support assembly, the leg support assembly comprises a leg support plate detachably mounted on one side of the movable leg for supporting the thigh; restraint belts for restraining the thigh and Velcro adhered to the restraint belts are respectively fixed on both sides of the leg support plate.

[0007] As a preferred technical solution of the present invention, at least a pair of limiting rods are fixed on one side of the leg support plate and matched with nuts; a strip-shaped limiting groove that matches the limiting rods is opened on one side of the movable leg.

[0008] As a preferred technical solution of the present invention, a hinge seat is provided at one end of the leg support plate, and is hingedly connected to a second leg support plate for supporting the calf.

[0009] As a preferred technical solution of the present invention, a limiting column 1 is fixed on one side of the leg support plate 2, and several springs are installed to adjust the restoring force; a limiting column 2 installed with a spring is fixed on the side of the movable leg close to the leg support plate 2.

[0010] As a preferred technical solution of the present invention, the two sides of the leg support plate are respectively fixed with a restraining belt for restraining the thigh and a Velcro fastener bonded to the restraining belt.

[0011] As a preferred technical solution of the present invention, a connecting bracket is fixed on the other side of the movable leg; the connecting bracket is fixed with several anti-collision tubes on the side close to the other connecting bracket for mitigating the impact of the movable leg.

[0012] As a preferred technical solution of the present invention, side pads for fitting the sides of the legs are fixed on the connecting bracket.

[0013] As a preferred technical solution of the present invention, a universal wheel is fixed to the bottom of one end of the movable leg for rotating with the movable leg; the other end of the movable leg is rotatably connected to the bottom of the support frame.

[0014] As a preferred technical solution of the present invention, the bottom of the leg support plate is rotatably connected to a pedal for the patient to step on through a vertical rod; a fixing belt for fixing the patient's feet is fixed to the top of the pedal.

[0015] As a preferred technical solution of the present invention, a universal wheel 2 is fixedly installed at the bottom of the pedal to cooperate with the rotation of the pedal.

[0016] The present invention has the following beneficial effects:

[0017] 1. The present invention has multiple anti-collision tubes fixed on one side of the connecting bracket for reducing the impact of the movable legs. When the legs and feet drive the pedals and the movable legs to rotate for rehabilitation training, the two movable legs move closer to each other, and the anti-collision tubes buffer the impact, avoiding concussion of the patient's legs and improving the safety of training.

[0018] 2. The present invention hinges the leg support plate 1 to the leg support plate 2 to assist in supporting the calves, thereby facilitating the exercise of the patient's calves; when it is necessary to sit with the legs straight to perform leg opening or closing training, the leg support plate 2 is flipped up so that the leg support plate 1 and the leg support plate 2 are both in a horizontal state, which can fix the legs, enable sitting with the legs straight to perform leg opening and closing movements, and realize training in various postures.

[0019] 3. The present invention installs springs when the patient needs to perform leg bending and straightening training. The thigh is fixed by a restraint belt, and the calf is placed on the leg support plate 2. Then the leg is bent or straightened to drive the spring to stretch or contract, thereby performing rehabilitation training for the patient's legs, which is convenient for the patient's recovery after leg burns. The model of the spring is selected according to the needs of the patient, and the number of springs is increased or decreased according to needs.

[0020] 4. The present invention is connected to a pedal by rotating the bottom of the leg support plate 1. When the leg support plate 2 is turned down, the foot is stepped on the pedal to bind the foot with a fixed belt, and then the legs are opened and closed, which drives the pedal and the movable leg to open or close accordingly, thereby completing the leg rehabilitation training and restoring strength.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
