Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, specifically to a split-type bedside assistive handrail for hemiplegic patients to sit up. Background Technology

[0002] Hemiplegia, also known as paralysis of one side of the body, refers to motor dysfunction of the upper and lower limbs, facial muscles, and lower part of the tongue on the same side. It is a common symptom of acute cerebrovascular disease. Patients with mild hemiplegia can still move, but when walking, the upper limb is often flexed and the lower limb is extended; the paralyzed lower limb makes a semi-circular movement with each step. This distinctive gait is called hemiplegic gait. Severe cases often result in bedridden patients who lose their ability to live independently. Based on the degree of hemiplegia, it can be classified as mild paralysis, incomplete paralysis, and complete paralysis.

[0003] Currently, it is quite difficult for hemiplegic patients to get out of bed because they have difficulty exerting force. Generally, medical staff or family members pull the patient's arm to help them get up. However, sometimes the medical staff or family members may not be around, making it even more inconvenient for the patient to get up. Utility Model Content
