Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training equipment, and particularly relates to an upper limb movement training device for stroke hemiplegic patients. Background Art

[0002] Stroke is a common neurological disease, and patients often have sequelae such as hemiplegia, which seriously affect their quality of life. During the rehabilitation treatment process, the recovery of upper limb motor function is particularly important. Traditional upper limb movement training methods mainly rely on the manual operation of physicians or therapists, which are not only inefficient but also difficult to perform personalized training according to the specific conditions of patients. Therefore, it is of great significance to develop an upper limb movement training device that can automatically and accurately control the training intensity and adapt to the individual differences of patients.

[0003] At present, there are already some upper limb movement training devices for stroke hemiplegic patients on the market. Most of these devices use mechanical structures to simulate upper limb movements and achieve the automation of training actions through motor drive. However, these devices generally have some problems. First of all, they can only provide a fixed training intensity and cannot be adjusted according to the actual situation of patients, which easily leads to overtraining or undertraining. Secondly, these devices lack an accurate assessment of the patient's motor ability and cannot provide personalized training programs for patients. Finally, the operation of these devices is complex and requires professional personnel for operation and maintenance, increasing the use cost and difficulty.

[0004] The patent with the application number CN202023119614.1 discloses a forced use training device for hemiplegic limbs of stroke patients, including a waistband, a wrist guard, and a spring. The waistband is matched with the human waist. The waistband includes a belt body, a buckle, and a sliding sleeve. The buckle is arranged at one end of the belt body, and a plurality of locking holes are arranged at the other end of the belt body. The buckle is matched with the locking holes. Two sliding sleeves are sleeved on the belt body and can move along the belt body. There are two wrist guards, which correspond to the sliding sleeves. One wrist guard is matched with the human upper arm, and the other wrist guard is matched with the human lower arm. There are two springs, and the wrist guard and the sliding sleeve are connected by springs. The present invention can forcibly remind patients to exercise the hemiplegic upper limb on one side, avoid the functional degradation of the hemiplegic upper limb on one side due to long-term disuse, and improve the rehabilitation effect and progress.

[0005] However, the above patent technology is a wearable device and does not solve the technical problems existing in the prior art. Summary of the Invention

[0006] The purpose of the present invention is to provide an upper limb movement training device for stroke hemiplegic patients to solve the problems raised in the above background art:

[0007] (1) In the prior art, the main focus is on the optimization of mechanical structures and the simulation of training movements, and how to pay attention to the individual differences of patients and the adaptive adjustment of training intensity.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0014] The wearing component includes a suspension rope and a sleeve. The upper end of the suspension rope is fixedly connected to the slider of the sliding component, and the lower end of the suspension rope is fixedly connected to the sleeve;

[0015] Before use, the patient wears the sleeve. The patient uses the wearing component to pull the slider of the sliding component to move towards the end of the arc-shaped slide rail, and controls the magnitude of the torque of the rotating shaft of the swing component during the upper limb movement training of stroke hemiplegia patients by triggering the number of proximity switches of the sensing component through the slider of the sliding component.

[0016] On the basis of the above technical solutions, the present invention can also be improved as follows.

[0017] Furthermore, it further includes a driving component. The driving component includes a servo motor with adjustable torque and a gear transmission mechanism. The output shaft of the servo motor is driven by the gear transmission mechanism between the rotating shaft of the swing component.

The arc-shaped guide rod is located inside the arc-shaped slide rail. The two ends of the arc-shaped guide rod are respectively fixed to the starting end and the ending end of the arc-shaped slide rail. The slider is sleeved on the arc-shaped guide rod and also cooperates with the arc-shaped guide rod. The return spring is sleeved on the arc-shaped guide rod. One end of the return spring abuts against the slider, and the other end of the return spring abuts against the ending end of the arc-shaped slide rail.

[0023] By introducing the sensing assembly and the driving assembly, the present invention realizes the real-time evaluation of the upper limb motor ability of the patient and the precise control of the training intensity. The sensing assembly can monitor the movement state of the patient in real time. By processing and analyzing these data, we can accurately judge the motor ability and training needs of the patient. The driving assembly can automatically adjust the training intensity according to the feedback of the sensing assembly to ensure the safety and effectiveness of the training.

[0024] In addition, the present invention also adopts the design of the wearing assembly, enabling the patient to train more conveniently.
