Description

Technical Field

[0001] The present invention relates to the field of medical technology, in particular to a rehabilitation device for the upper limbs of hemiplegic patients. Background Art

[0002] According to the 2019 Systematic National Overall Burden of Disease Study, stroke has become the leading cause of death in my country, and the number of stroke deaths in my country accounts for almost one-third of all stroke deaths worldwide. Ischemic stroke (i.e., cerebral infarction) is the most common type of stroke, accounting for approximately 80% of all strokes. Even with active medical treatment, the mortality rate can still be as high as 60% to 80%, and approximately two-thirds of surviving patients are left with severe disabilities. More than 60% of stroke patients present with severe and persistent upper limb motor impairment and lack effective grip strength. Due to the loss of autonomy in daily living activities, the restoration of upper limb motor function remains the main goal of rehabilitation. Existing rehabilitation equipment is insufficient to allow patients to exercise their fingers, forearms (the part of the arm connected to the wrist is called the forearm), and upper arms (the part of the arm connected to the shoulder is called the upper arm) simultaneously, which can easily cause secondary injuries during rehabilitation exercises.

Through the setting of the first spring telescopic rod, the patient's finger can adapt itself during the training process, which can effectively protect the patient's finger. At the same time, it can be adapted according to the thickness of the patient's finger. The setting of the rod and the socket makes the sixth fiber binding band more firmly fixed when tightened; the patient's grip strength and the force exerted on the finger movement are also monitored by the thin film pressure sensor. The monitoring data can be connected to the display for a more intuitive display, thereby better training the patient; multiple cavities are connected by a hollow hose to make the pressure in the multiple cavities consistent, so as to better adapt the fingers for rehabilitation training; the fingers make a cycle of gripping and releasing, with a frequency of 30 seconds / time, to avoid damage to the patient's joints caused by excessive frequency.
