Technical Field

The utility model belongs to the technical field of medical clinical nursing facility, concretely relates to rehabilitation and nursing bed.

Background

The aforementioned rehabilitation nursing bed can also be called a medical nursing bed, and technical information about the rehabilitation nursing bed is not lacked in published Chinese patent documents, such as "combined nursing bed" recommended by CN103156743B, which has positive significance: the movable backrest is arranged on the fixed bed body, and the wheelchair which can be separated from the bed body is arranged from the outside of the movable backrest to one side of the bed tail, namely from the hip position of a human body, so that the nursing bed has the function of the wheelchair and meets the requirements that a nursed person moves to the outdoor for activities, eats in a restaurant, bathes in a bathroom, can sit for stool and urine, and the like. For another example, CN101978939B provides a "medical foldable nursing bed", which can be completely folded to facilitate transportation, storage, etc., specifically, the left and right frames are hinged to the middle base frame, but the folded state is pi-shaped, i.e. the left and right frames are folded from two ends to the middle, and the folded state is not in the category of compression-type folding in the height direction, so the volume is still relatively large. Further, CN101461751B describes a liftable medical nursing bed, which is a patent that a bed frame is hinged to a base through a Jiong-shaped support frame to realize quick lifting. Further, the patent of "automatic folding electric multifunctional nursing bed" disclosed in patent publication No. CN103405314B can embody multiple effects of different operation and same work as the aforementioned CN101978939B, and refer to paragraphs 0006 to 0008 of the specification of the patent.
