Background
Hospital beds can also be called medical beds, nursing beds and the like, are used when patients are in rest, are mainly used in various hospitals, village and town health hospitals, community health service centers and the like, and are designed into bed body structures with guardrails arranged at the bedside by people in order to improve the safety of the hospital beds and prevent the hospital beds from falling from the hospital beds for babies and children.
So now a number of highly safe pediatric beds have been developed, which by the team through regular visits to several medical institutions and users and through extensive search and reference we have found that existing pediatric beds are mainly represented as the pediatric beds disclosed under the publication numbers KR101294314B1, US5289603A, US20030038725a1 and CN103027523B, wherein the pediatric bed disclosed under the publication number KR101294314B1, is structured to provide a foldable front door at the front of the bed and to form a transparent window on a protection plate, while having protection plates at a certain height around both sides and the rear of the bed of the cot, providing a front door for providing a bed for a pediatric patient and an auxiliary bed for a guardian installed to be opened and closed by hinges provided on both side panel portions of the protection panel, which in a folded state can be used as a protection plate for the front side of a juvenile mattress, the structure is similar to that of the added guardrails, the moving range of children is limited by increasing some limiters as a main mode, the limiters limit the movement of the children and often generate certain potential safety hazards for the children, for example, soft limbs of the children are easily clamped into the gaps of the guardrails, or the children curiosity want to fall down on the auxiliary bed connected by the hinges, and as a result, the hinges loosen, fall and pound the children, so that the equipment increases other potential safety hazards after solving the potential safety hazards, and in order to facilitate the use of medical equipment such as an atomizer, a needle water fixing frame and other equipment, too many articles are often needed to be kept on a bed plate, so that the smoothness and the multiple functions of the hospital bed are needed to be kept, and meanwhile, the problem that the children fall down from the bed is solved, and the main research direction of the existing hospital bed is provided.
