Description

Technical Field

[0001] This utility model relates to the field of upper limb exercise device technology, and in particular to an upper limb exercise device for stroke patients. Background Technology

[0002] Stroke is characterized by a high disability rate. Patients often suffer from upper limb motor dysfunction, which seriously affects their ability to live independently. Clinical studies have shown that scientific early rehabilitation training can significantly improve upper limb muscle strength, joint range of motion and nerve function recovery. However, traditional upper limb rehabilitation exercise devices have limited functions and complex height adjustment structures, making it difficult to adapt to the personalized needs of patients with different body types.

[0003] For example, the patent publication number CN222693735U discloses an upper limb exercise device for stroke patients, which includes two support frames and a seat. The seat is located between the two support frames. Each of the two support frames is connected to a support plate through a lifting adjustment component. A top plate is horizontally fixed at the top of the two support plates. The top plate is provided with a first exercise component for assisting the stroke patient's upper limb extension and swinging, and a second exercise component for weight-bearing exercise of the stroke patient's upper limb. The beneficial effects of this utility model are: while providing weight-bearing exercise for the upper limbs of stroke patients, it can also effectively assist stroke patients in extending and swinging their upper limbs. It also has a height adjustment function, so it can be used by stroke patients with different upper limb lengths, greatly improving its practicality and making it suitable for promotion. However, the height adjustment is done manually by fixing it with bolts, which is not only cumbersome and time-consuming, but also lacks lateral force training, greatly reducing its practicality.

[0004] Therefore, we propose an upper limb exercise device for stroke patients. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an upper limb exercise device for stroke patients.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An upper limb exercise device for stroke patients includes a base and an auxiliary mechanism. A metal frame is fixedly connected to the upper surface of the base. A groove is formed on the inner side of the metal frame. The auxiliary mechanism is movably arranged inside the groove. The auxiliary mechanism includes a push-pull rod, a steel wire rope, and a hook-lock spring. The push-pull rod is slidably arranged inside the groove. A pulley is fixedly installed at the bottom end of the push-pull rod. Two sets of pulleys are symmetrically arranged. A steel wire rope is movably engaged above the pulley. A pull ring is fixedly connected to one end of the steel wire rope, and a hook-lock spring is fixedly connected to the other end of the steel wire rope. The steel wire rope and the top of the hook-lock spring are fixed by welding. The bottom end is fixed by welding. A drive motor is fixedly installed on one side of the metal frame. A transmission gear is connected to the output end of the drive motor. A rack is meshed on one side of the transmission gear. The rack is movably arranged in a slide groove one. The push-pull rod is fixedly connected to one side of the rack. A horizontal block is fixedly welded to one side of the metal frame. A slide groove two is opened on one side of the horizontal block. A sliding block is movably arranged inside the slide groove two. A sponge pad is fixedly connected to the inner side of the sliding block. Two sets of sliding blocks are symmetrically arranged. A fastening spring is fixedly installed at the end of the sliding block away from the sponge pad. A handle is fixedly connected to one side of the sliding block. Anti-slip texture is opened on the top of the handle.

[0007] As a further improvement of this utility model: a mounting box is provided on one side of the upper surface of the base, a limit opening is provided at the top of the mounting box, and a hook-lock spring is movably provided inside the mounting box.

[0008] As a further improvement of this utility model: a seat is fixedly installed in the center of the upper surface of the base, a rubber pad is provided above the seat, and the seat and the base are an integral structure.

[0009] Compared with the prior art, this utility model provides an upper limb exercise device for stroke patients, which has the following beneficial effects: 1. This utility model, through the cooperation of the drive motor, transmission gear and rack, can drive the push-pull rod to move vertically in the slide groove. It can be flexibly adjusted according to the patient's height. At the same time, the patient can also pull the pull ring to use the steel wire rope above the pulley and the hook lock spring connected to the other end to carry out resistance training, thereby effectively improving the efficiency of rehabilitation training.

[0010] 2. In this utility model, the fastening spring and the sliding block groove cooperate with each other. When the patient holds the handle and pulls it to both sides, the fastening springs inside the two sides provide elasticity, which makes it convenient for the patient to pull laterally. The anti-slip texture on the handles on both sides makes it easy for the patient to grip, thereby effectively improving the practicality of the device.
