Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation nursing seats, and in particular to an upper limb rehabilitation safety nursing seat. Background Art

[0002] A chair is a kind of seat with a backrest and sometimes armrests. During the rehabilitation process of patients, patients with limited mobility often need to use a chair device to move around, and a common chair device is a wheelchair. A wheelchair is a chair with wheels that can help replace walking. It is an important means of transportation for the injured, sick, and disabled for home rehabilitation, turnover transportation, medical treatment, and outdoor activities. Wheelchairs not only meet the mobility needs of people with limb disabilities and limited mobility, but more importantly, they facilitate family members to move and take care of patients, allowing patients to exercise and participate in social activities with the help of wheelchairs. Although existing wheelchairs can help patients travel, due to their relatively single functions, they can often only meet simple movement. When patients sit in the chair for a long time, they are also restricted from exercising, making it difficult to meet the nursing needs for rehabilitation exercises for the upper limbs, which greatly affects the use effect of the device.
