Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation exercise, in particular to an upper limb rehabilitation exercise device for severe hemiplegic patients. Background Art

[0002] Patients with severe hemiplegia are often bedridden, unable to control themselves, and lose their ability to live. Therefore, exercise training for patients' limbs is very important and critical. In order to perform rehabilitation training for patients with severe hemiplegia, some special rehabilitation nursing devices are needed. Patients have poor active awareness and need passive limb rehabilitation training. However, when performing rehabilitation training on patients, existing devices passively rotate the patient's joints, thereby increasing the burden on the patient's joints during the rehabilitation training process and causing joint damage. Summary of the Invention

[0003] In response to the problems in the prior art, the present invention provides an upper limb rehabilitation exercise device for severe hemiplegic patients, which can protect the patient's joints, increase the rehabilitation exercise time, and ultimately speed up the patient's recovery.

The reciprocating assembly can control the reciprocating angle and rotation speed of the forearm support plate. During the early stage of the patient's exercise, the minimum angle and the minimum rotation speed are adopted, and the angle and the rotation speed are gradually increased in the later stage. The patient is exercised step by step, which can effectively protect the patient's joints, improve the rehabilitation exercise time, and ultimately speed up the patient's recovery.

The smaller the angle between the connecting shaft and the second rotating shaft, the smaller the reciprocating rotation angle of the first rotating shaft. Through the above setting, it can be directly adjusted during the patient's rehabilitation exercise. The above structure can enable the patient's left forearm and the patient's right forearm to cross rehabilitation training, and unidirectional rehabilitation training.

The third guide rod is set so that when the fourth motor drives the screw to rotate, the screw moves along the direction of the third guide rod, so that the first straight plate and the second straight plate move together along the direction of the third guide rod. The first straight plate or the second straight plate can push the connecting wheel to move on the fourth rotating shaft, and the rotation of the connecting wheel also drives the fourth rotating shaft to rotate. The movement of the connecting wheel on the fourth rotating shaft can change the rotation speed of the second rotating shaft, and finally adjust the reciprocating rotation speed of the first rotating shaft, that is, the reciprocating rotation speed of the forearm support plate. Through the above setting, it can be directly adjusted during the rehabilitation exercise of the patient.
