New description: [New technical field] 曰This creative department provides a wheelchair structure that can be used as a pusher bed, especially if it is technically provided. The wheelchair structure can be quickly converted into a pusher bed, which is convenient for people with reduced mobility. Change the sitting or lying position, or convert to a first-aid bed user. • [Prior Art] • The wheelchair is the best aid for people with reduced mobility, which can help them move longer distances. Because of their large size and most of their use, they need the assistance of another person. In order to take care of the user of the wheelchair, it is necessary to stay on the side for a long time, and when the wheelchair is used, it can only be placed on the side, so that it is a waste of space for the wheelchair to stand still. Furthermore, in general, wheelchairs are used for people with reduced mobility. They also provide services for critically ill patients. Because they are critically ill patients, it is quite difficult to move between wheelchair beds. If the critically ill patients are in wheelchairs, they will have temporary When the dog roll condition product needs cp R first aid, it is still necessary to find the bed for the patient to dispose and lay down, in order to be able to give emergency treatment, or directly put the patient on the ground to lay a first aid, find a disease, delay the bed and move inconveniently, and directly move To the ground, on the one hand, it is unhygienic and inconvenient to intubate first aid; if the wheelchair can be pulled directly and the patient becomes a pusher without moving the patient, the patient can immediately lie flat and c PR first aid, which will save time. And to avoid the inconvenience of moving the patient, and the push bed can be immediately moved to the place where the rest or first aid is needed, the wheelchair pusher 4 M340810 will be the gospel of the patient and can also relieve the work pressure of the care. Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure with more ideal and practicality, the actual patient and the care center are eager to meet the needs of the industry, and the relevant industry must strive to develop the breakthrough goal and direction. . v In view of this, the creator is a professional medical practitioner who, after detailed design and careful evaluation of the above objectives, will eventually have a practical and practical creation.
