Description

Assisted standing trolley with combined seat pan

technical field

The invention relates to the technical field of old-age assistance equipment, in particular to an auxiliary standing trolley with a combined seat plate.

Background technique

With the continuous improvement of people's living standards and the continuous improvement of social civilization, the voice of caring for the elderly and the disabled is getting louder and louder. Due to the gradual decline of the physical function of the elderly, it becomes more and more difficult to walk, especially for those due to For the elderly who have difficulty in mobility due to diseases, as the body ages, the physical fitness of the elderly is getting worse and worse, and it is more difficult to sit, stand and walk, especially when standing up, the legs need to be spread out at a larger angle, and the muscles must be overcome. The larger the weight, the more force the muscles bear than when walking, making it very difficult for the elderly to get up, and even some elderly people need to be assisted by others to get up and stand, so they often need to be accompanied by their family members to complete their daily routines. Especially for those elderly people in wheelchairs, sitting in a sitting position for a long time, long-term lack of standing and walking exercises can easily lead to muscle atrophy in the legs, which is not good for the health of the elderly. Therefore, the elderly need to get up and get rid of the wheelchair in a timely manner. Physical activity, and at the same time, when the elderly need to rest, go to the toilet and other necessary physiological activities, they all need to stand up. Due to the inconvenience of the elderly and the weakness of the legs, it is relatively difficult to get up and leave the wheelchair alone and there are certain safety risks. Stand up and get out of the wheelchair with the assistance of the old man, but it is impossible for the old man to be surrounded by people all the time, and it is inconvenient to need the assistance of others. Therefore, a device for assisting the old man to stand up and stand is urgently needed.
