Description

Technical Field

[0001] The present invention belongs to the technical field of mobile hospital beds, and particularly relates to a sitting and lying multi-functional transfer chair bed. Background Art

[0002] When treating patients in a hospital, it is usually necessary to transfer the patient's position to cooperate with the use of medical instruments, such as transferring the patient from a CT machine in the CT room back to the hospital bed, or from the hospital bed to the operating table. Conventional hospital beds in the ward cannot be moved, so specially designed transfer wheelchairs are required for transfer. Transfer wheelchairs occupy a large area, and in order to move freely in the ward, ordinary transfer wheelchairs have high requirements for the space of the ward.

[0003] The prior art CN218420259U discloses a split-type nursing bed. The nursing bed includes a bed frame. The wheelchair includes a lower wheelchair frame fixed with wheels and an upper wheelchair frame. Mattresses are provided on both the bed frame and the upper wheelchair frame. An elevating mechanism for elevating the upper wheelchair frame is provided between the upper wheelchair frame and the lower wheelchair frame. The nursing bed has a wheelchair placement area for placing the wheelchair. Two first guiding members are provided on the side of the bed frame adjacent to the wheelchair placement area, and both of the two first guiding members are arranged in the front-back direction. At least one second guiding member for cooperating with the first guiding member is provided on each of the left and right sides of the lower wheelchair frame. The side surface of the first guiding member adjacent to the wheelchair placement area is a guiding surface; when the wheelchair is located in the wheelchair placement area, the second guiding members on the left and right sides are located between the two guiding surfaces. Therefore, the prior art has the advantage of facilitating the combination or separation between the wheelchair and the nursing bed. However, this prior art only simply arranges a storage space for the wheelchair in the nursing bed, and still fails to achieve an integrated combination of the wheelchair and the hospital bed.
