Description

Wheelchair structure that can be used as a push bed

technical field

The utility model relates to a wheelchair structure which can be used as a push bed.

Background technique

Wheelchairs are the best assistive devices for people with disabilities, which can help them move for a long distance. Because of their large size and most of them need the assistance of another person when using them, the helpers usually need to take care of wheelchair users. Therefore, it is necessary to be on the side for a long time, and when the wheelchair is used up, it can only be placed on the side, so that the standing of the wheelchair forms a waste of space.

Furthermore, general wheelchairs are not only used by people with reduced mobility, but also for critically ill patients. Because they are critically ill patients, it is quite difficult to move between wheelchair beds. When the situation requires CPR first aid, it is necessary to find a hospital bed for the patient to move and lie down before first aid, or directly put the patient on the ground to lie flat for first aid. It takes time to find the bed and it is inconvenient to move, and moving directly to the ground is unhygienic on the one hand. It is also inconvenient for intubation first aid; if the wheelchair can be stretched immediately without moving the patient, the wheelchair can be turned into a push bed so that the patient can immediately lie flat for CPR first aid, which will save time and avoid the inconvenience of moving the patient. And the push bed can also be immediately moved to the place where rest or first aid is required, then the described wheelchair push bed will be the gospel of the patient, and can also reduce the work pressure of the nurse.
