Description

Technical Field

[0001] The invention relates to the technical field of neurology nursing, and in particular to a neurology nursing hemiplegic patient walker with an anti-fall function. Background Art

[0002] Hemiplegia is a neurological disease. Due to damage to the cortex, subcortical white matter and internal capsule of the brain's motor area, it leads to paralysis of one upper or lower limb. This paralysis is usually manifested by increased muscle tone, hyperreflexia of the tendon, positive pathological signs, and is often more severe with distal limb paralysis. Hemiplegic patients may also have sensory impairment in the same area, such as decreased or loss of pain and temperature sensation, deep sensory impairment and cortical sensory impairment. In addition, hemiplegic patients may also experience lateral gaze paralysis, that is, both eyes cannot look toward the lesion side. If the dominant hemisphere is diseased, it may also be accompanied by motor or sensory language disorders. For the treatment of hemiplegia, it is necessary to formulate an individualized treatment plan based on the patient's specific situation. Generally speaking, the treatment of hemiplegic patients includes drug therapy, physical therapy, rehabilitation therapy, etc. Drug therapy mainly uses drugs to relieve symptoms and promote nerve repair Physical therapy and rehabilitation treatment are mainly carried out through targeted training and guidance by professional rehabilitation technicians or therapists to help patients restore muscle strength, balance, coordination, etc., and improve the quality of life. During the training process, due to the insufficient limb support on one side of the patient, the patient is prone to fall during exercise, which causes the patient to rely on the protection of caregivers to exercise safely. Some patients exercise independently with walkers. During the exercise, if the patient's hand strength is insufficient to support the body, the patient will fall. The traditional surround-type walker is very inconvenient to use for patients with higher mobility difficulties, and the center of gravity of the walker is high. When the patient's body tilts, it is easy to cause the walker to overturn together, posing a major safety hazard. Summary of the invention

At this time, the patient buries his legs and passes through the anti-fall belt 11. At this time, the supporting electric push rod 5 is started to drive the connecting gear rod 6 to slide upward. At this time, the connecting gear rod 6 drives the support block 7 to separate from the foundation of the ground and release the support for the lower mounting ring 3, so that the universal wheel 4 is in contact with the ground for easy movement, and the connecting gear rod 6 is connected to the ground through the gear block during the upward sliding process. The meshing of the transmission gear 8 drives the transmission gear 8 to rotate, so that the inner support rod 9 drives the upper supporting ring 10 to flip upward. At this time, the upper supporting ring 10 flips up and contacts each other to close into a complete circle to surround the patient's body, and the anti-fall belt 11 moves upward under the drive of the upper supporting ring 10 and provides preliminary support and protection for the patient's crotch. When the patient loses support and falls during mobile exercise, he can prevent himself from falling by holding the upper supporting ring 10. When the patient's hand strength is insufficient, the anti-fall belt 11 prevents the patient from falling by supporting the patient's buttocks. Example
