Physical Rehabilitation Trainer

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a limb rehabilitation training device.

Background technique

Patients with mild hemiplegia, especially those with injuries to the upper or lower limbs, sometimes need to properly move their joints for rehabilitation training while recuperating to speed up the recovery effect. At present, rehabilitation training is generally a "one-to-one" training method between a therapist and a patient, that is, the therapist assists the patient to complete various training movements of the upper or lower limbs, which is inefficient; and requires the therapist to assist each time. , therapists are labor-intensive and inconvenient.

In order to change this situation, it is necessary to design a limb rehabilitation trainer to replace the role of the therapist in assisting the patient, and this case was born.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide a multifunctional rehabilitation training device that promotes the recovery and improvement of the patient's limb motor function.

In order to solve the above technical problems, the limb rehabilitation training device of the present invention includes a base, a crank-slider mechanism arranged under the base, a motor for driving the action of the crank-slider mechanism, and the motor is fixedly connected with the base; The leg collar is used to drive the action of the human body's legs; the massage wheel device is used for massaging the foot of the human body, and the massage wheel device is slidably connected to the base.
