Description

A wheelchair combined multifunctional nursing bed

technical field

The utility model relates to a nursing bed, in particular to a wheelchair combined multifunctional nursing bed.

Background technique

At present, there are two main types of nursing beds on the market: one has a relatively simple function, such as only lifting the back and raising the legs; the other is an imported product with relatively many functions, but the price is expensive and unacceptable to the general population. In the face of the increasing number of elderly people in our country, the one-child family is very common, and the work of caring for the elderly and the sick is very arduous, which requires a simple structure, full function, practical and affordable nursing bed to reduce people's burden.

In the nursing process, the transfer operation between the wheelchair and the bed is a great burden for the caregiver. Therefore, a nursing bed combined with a wheelchair and a bed has emerged. The wheelchair of this nursing bed can be disassembled and used as a separate Wheelchair use, it can also be assembled to the bed as part of the bed body, so that the patient does not need to suffer from the transfer between the wheelchair and the bed. For example, Chinese patent application No. 201310029447.7, the application publication date is May 22, 2013, and the name of the invention is: A wheelchair bed consisting of a wheelchair and a bed with bent legs, standing, defecation, and hair washing. The wheelchair bed of this application is composed of Wheelchair, bed and chair connecting frame or movable bed block are butted and assembled and connected and positioned or separated by positioning parts; the seat surface and part of the bed surface are divided into two layers: support and upper layer, the overall shape of the surface is comb-like, and the teeth are arranged in the teeth. , the tooth end is hinged with the corresponding support; the calf support, the pedal support and the corresponding linkage or lifter are arranged; the head support is in contact or hinged with the bed and chair connecting frame; Lifters or linkage rods or linkage parts; linkage rods are placed in whole or in sections and stretched sleeves or electric extension rods or threads or live or hinged shafts are arranged on the linkage rods; Positioning parts are arranged between the supports or between the linkage rods; the seat surface is divided into two parts: the buttocks and the thigh surface, and the outer bed surface support of the pedal surface, the outer bed surface support of the thigh surface, the outer bed surface support of the calf surface and the corresponding linkage parts are arranged or lift rod. By connecting or stripping the wheelchair from the bed, the application enables both the wheelchair to be used alone and the ability to sleep without leaving the wheelchair, which to a certain extent solves a major problem in the nursing process of the elderly and patients with limb diseases . However, the overall structure of the application is relatively complex. The turning over action requires the side bed board to be lifted as a whole to form an upside-down "V" shape. Both the back-lifting action and the turning over action require the synchronous movement of the bed body and the wheelchair, which is complicated in structure and inconvenient to use; and , the wheelchair bed does not have the function of rehabilitation training, and cannot help the patient to perform physical exercise.

In addition, there are many wheelchair bed solutions similar to the above-mentioned applications, such as patent application numbers 201210048295.0, 201520145808.9, 201611065305.6 and 201710807816.9, etc. However, most of these applications have only one function due to the interference of back-lifting or turning over structures, and none of them have The defects of rehabilitation exercise function cannot meet people's needs.
