Upper limb rehabilitation training system with active-passive modes

Abstract

The invention belongs to the technical field of medical instruments, and relates to a rehabilitation training system, in particular to an upper limb rehabilitation training system with active-passive modes. The technical scheme includes that the upper limb rehabilitation training system with the active-passive modes comprises a handle, a mechanical arm, a spindle, an encoder, a computer, a display, a motor, a clutch, a coupler, a belt pulley, a belt pulley shaft, a synchronous toothed belt and a rehabilitation device base. Compared with equipment in the past, the upper limb rehabilitation training system has the advantages that active acting force is provided for a patient needing rehabilitation, the mechanical arm can drive an arm of the patient to perform rehabilitation training in the active mode so as to achieve better rehabilitation training effects, and a threshold safety module is arranged inside the computer so that safety of the patient in rehabilitation training can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a rehabilitation training system, in particular to an upper limb rehabilitation training system with active and passive modes. Background technique [0002] The traditional method of rehabilitation treatment for some common middle-aged and elderly diseases (such as: stroke, hemiplegia, senile dementia) and disabled patients is that doctors conduct hands-on training for patients. There are some problems in this training method: First, one therapist can only perform exercise training on one patient at the same time, the training efficiency is low, and due to the therapist's own reasons, it may not be possible to ensure that the patient receives sufficient training intensity and the therapeutic effect It mostly depends on the experience and level of the therapist; secondly, the training parameters (movement speed, trajectory, intensity, etc.) cannot be accurately controlled an...

There are some problems in this training method: First, one therapist can only perform exercise training on one patient at the same time, the training efficiency is low, and due to the therapist's own reasons, it may not be possible to ensure that the patient receives sufficient training intensity and the therapeutic effect It mostly depends on the experience and level of the therapist; secondly, the training parameters (movement speed, trajectory, intensity, etc.) cannot be accurately controlled and recorded, which is not conducive to the determination and improvement of the treatment plan; moreover, the rehabilitation evaluation indicators are not objective enough, which is not conducive to hemiplegia In-depth research on the laws of neurorehabilitation of patients; in addition, real-time and intuitive feedback information cannot be provided to patients, the training process is not attractive, patients accept treatment passively, and the initiative to participate in treatment is not enough

Although the entertainment and safety of the whole device are good, but because it only has a passive driving mode, it can only give the patient a resistance effect through the mechanical arm during rehabilitation training, and the patient can only do rehabilitation training in passive and damping modes, not by The robotic arm drives the patient's arm for active rehabilitation training, which is not applicable to some patients
