Turning-over bed or multi-functional nursing wheelchair-bed composed of lying wheelchair and bed plates

Abstract

The invention relates to a turning-over bed or multi-functional nursing wheelchair-bed composed of a lying wheelchair and bed plates. The turning-over bed or multi-functional nursing wheelchair-bed comprises the lying wheelchair, bed plates and turning-over components. The surfaces of the chair or the bed for turning-over are in comb-shape with teeth arranged against one another, and the ends of the teeth are coaxially hinged to corresponding brackets. Bed-chair connecting brackets or movable bed plates are arranged, a turning-over power mechanism composed of the turning-over components is arranged on the bed-chair connecting brackets or the movable bed plates, and the turning-over action is achieved by fine methods. With the utilization of mature technology of fully flat wheelchair and turning-over nursing bed, the reliable structure and components applied on the wheelchair and turning bed are combined skillfully and uniquely, the wheelchair and the bed-chair connecting brackets can be connected and disconnected conveniently, the patient can respectively use the handy wheelchair or sleep on a wide bed without leaving the wheelchair, so that all the functions of standing, sitting, lying, rotating, pumping legs, defecation, washing hair, moving and rehabilitation training are achieved and a major problem of nursing and rehabilitating the elderly and limb-disordered patients is solved.

Description

technical field [0001] The invention relates to a living and moving aid for the elderly or patients with lower limb diseases, in particular to a turning bed and a multi-functional rehabilitation wheelchair bed composed of a flat-lying wheelchair and a bed block. Background technique [0002] According to the results of patent literature retrieval and market status investigation, there is no product in the market that operates wheelchairs through bed blocks or bed-chair connecting frames. The lifting rods on the same side of the four corners of the surface are synchronously matched to realize, but this patent is just the opposite. Strict synchronous control of different lifting rods between the two, otherwise they cannot operate, and the patented schemes complete their respective actions; the eight joints of the four push rods in the comparative patented scheme are all hinged by spherical joints, and several push rods arranged on the spherical surface are required. The magn...

Problems solved by technology

[0002] According to the results of patent literature retrieval and market status investigation, there is no product in the market that operates wheelchairs through bed blocks or bed-chair connecting frames. Similar patent publications include CN 2012100482950, ​​in which the turning action is realized through synchronous cooperation of the lifting rods on the same side of the four corners of the wheelchair seat surface, but this patent is just the opposite, and the turning action is only realized by the lifting rods on the bed-chair connecting frame; the comparison The patented solution requires strict synchronous control of different lifting rods between the wheelchair and the bed during sitting, lying and turning operations, otherwise it cannot operate, and this patented solution completes its own action; the comparative patented solution has four push rods and eight push rods. The joints are all hinged by spherical pairs, and a number of magnetically controlled pins arranged on the spherical surface are needed to cooperate with the movement, while this patent does not require magnetically controlled pins to control the articular surface, and the structure is simple, safe and reliable; from a functional point of view, they are the same, but this patent The idea of ​​realizing the same function of the patent and the comparison patent is exactly the opposite, so the structures of the two are obviously different
