Description

a nursing bed

technical field

The invention relates to the technical field of nursing equipment, in particular to a nursing bed.

Background technique

At present, our country has entered the stage of accelerated aging. The needs of the elderly have formed a sharp contradiction with the lack of the current pension industry. The current nursing bed needs the help of transfer equipment to complete the movement of the elderly. The lack of richness of transformation will cause local tissues to be oppressed for a long time, and pressure sores are prone to occur. The transfer function can expand the living space of the elderly, improve the quality of life of the elderly, and solve some mental problems.

Chinese invention patent CN 105877944 A discloses a multifunctional nursing bed, which uses a bed frame assembly and a movable bed board assembly, the movable bed board assembly and the bed frame assembly are detachably connected, and the movable bed board assembly can be combined into a wheelchair. Conversion between bed and wheelchair. But there are four major problems in this technology: first, when the movable bed board assembly and the bed frame assembly are combined into a nursing bed, the back board and the triangular support board of the bed are supported, but the pedal part is fully supported by the electric cylinder. Support wastes energy at the same time and there is a risk of electric cylinder failure; second, this technology uses mosaic splicing, which is complicated, requires high precision in splicing operations, and has a low degree of automation, requiring manual auxiliary splicing; third, this technology nursing bed does not have Mobility, with displacement limitations. The 4th, this technical armrest adopts pin buckle type, and flexibility is poor, and wheelchair does not have lifting function. The reason why the inventor has these problems is because he did not consider that the active opening and closing of the movable plate can be realized by installing a motor on the bed frame assembly, but adopted a manual connecting rod. At the same time, the height of the movable bed board is equivalent to that of the bed frame, which cannot be overlapped.

Midest Company has developed and produced an ABS manual wheelchair bed, which requires additional assisting personnel to remove the side baffle of the bed when the bed and chair are separated, which is time-consuming and laborious.
