[0002] Long-term bed rest (or long-term bed rest, bedridden) refers to a clinical phenomenon in which the elderly have reduced their ability to live in daily life due to long-term illness and disability, and partially or completely need help from others, including long-term bed rest, sitting in a chair, and can only live indoors and cannot go out. The consequences of long-term bed rest are serious. Once it happens, the hope of recovery is small, so prevention should be the focus. Its causes include cerebrovascular disease, bone and joint disease, advanced age, senile dementia, etc.

[0003] Long-term bed rest can cause body stiffness and worsen the condition. 1. After long-term bed rest, the muscles of bedridden elderly people cannot be exercised for a long time, and they may have increased muscle tension, resulting in whole body stiffness; 2. Cerebral infarction is mainly a brain disease caused by damage or occlusion of cerebral blood vessels due to factors such as atherosclerosis and cerebral thrombosis. Due to damage to cerebral blood vessels and brain tissue, functional defects in the corresponding parts occur, and patients generally experience symptoms such as hemiplegia, coma, and body stiffness; 3. Cerebral hemorrhage is usually a brain hemorrhage disease caused by hypertension combined with small arteriosclerosis, cerebral artery malformations and other reasons. Due to the rupture of local cerebral blood vessels, local brain tissue ischemia occurs, resulting in dysfunction of the nervous system, and patients will experience symptoms such as stiff limbs, dizziness, and headaches. In addition, the stiffness of the elderly may also be related to factors such as cerebral infarction and meningitis.

[0004] For the elderly who are bedridden for a long time, their limbs are too stiff, which increases the difficulty of nursing for nurses when replacing the upper limb indwelling needles and accessories, and also brings pain to the patients. Based on the above reasons, an adjustable upper limb placement aid is urgently needed to solve the problems existing in the prior art. Utility Model Content
