Description

A multifunctional electric nursing bed

technical field

The present invention relates to a nursing bed, more particularly, to a multifunctional electric nursing bed, in particular to an electrically controlled nursing bed with functions such as lifting, lifting, bending legs, sitting on toilet and table board.

Background technique

With the continuous improvement of living standards, people's life expectancy is greatly prolonged, and the population is aging. More and more patients need long-term bedridden treatment or rehabilitation. These long-term bedridden patients who have lost their ability to take care of themselves mainly rely on hospitals, welfare institutions and families. It is difficult for them to get up and down, and they need staff to take care of their meals and daily life. For the medical staff and the family members of the patients, the daily nursing work of the patients is very heavy.

Because of this, nursing beds have become the main tool to help care for long-term bedridden patients, and the demand for nursing beds is increasing. Most of the existing electric nursing beds have basic functions such as lifting and getting up, but these basic functions are currently difficult to meet the needs of daily life and diet of long-term bedridden patients, among which the defecation problem of patients is particularly prominent. In order to solve the problem of patient's urination and defecation care, some nursing beds with toilet function have appeared on the market, but most nursing beds with toilet function are equipped with toilets at the bottom of the nursing bed. This method is not only structural It is complicated and will occupy the space at the bottom of the nursing bed, so that the nursing bed loses its original height lifting function; some nursing beds directly open a toilet hole in the middle of the nursing bed, and set an openable cover at the bottom of the toilet hole. When in use, open the cover on the toilet hole and place the bedpan under the toilet hole. This method is usually difficult to control the distance from the bedpan to the toilet hole. When the distance from the bedpan to the toilet hole is too far, the patient's excrement is also prone to occur. Problems such as external splashing make it inconvenient to use.

In addition, for long-term bedridden patients, their daily diet, entertainment and learning are often completed on the bed. In the existing nursing bed, a detachable table is usually placed on the guardrails on both sides of the nursing bed or is set beside the bed. A movable table board. The detachable table board can only be used on a horizontal nursing bed. It is difficult to apply to a nursing bed that can be tilted back and forth to facilitate the patient to get up and down. On the one hand, the table board is difficult to fix on the guardrail, on the other hand The inclined table board is difficult to place tableware and other items stably; although the movable table board can be used flexibly, it increases the space occupation, and usually adopts a single-sided cantilever support structure, and the stability and load-bearing capacity of the table board are also poor. It is also not convenient enough to use.

Based on the above problems of the existing electric nursing beds, it is necessary to propose solutions to the above pain points to improve and enrich the functions of the nursing beds.

SUMMARY OF THE INVENTION

1. The technical problem to be solved by the invention

The purpose of the present invention is to overcome the shortcomings of the existing electric nursing bed, such as complicated defecation structure, unreasonable spatial layout and easy interference with other functions, etc., and to provide a multifunctional electric nursing bed, adopting the technical scheme of the present invention, the nursing bed has an electric The functions of lifting, lifting, bending legs, sitting on the toilet and folding the table board, etc., and the closing or opening of the toilet mouth of the toilet mechanism and the telescopic movement of the bedpan support plate are designed in linkage, and the bedpan support plate can be opened with the toilet mouth. Closing and telescopic motion, when the toilet mouth is closed, the bedpan support plate shrinks upward, and when the toilet mouth is opened, the bedpan support plate expands downward. The structure design is simple and ingenious. When the toilet seat function is not used, the structure of the entire electric toilet mechanism is compact. , occupies less space, and does not affect the original functions of the electric nursing bed, such as lifting and sleeping; when using the toilet function, the bedpan support plate can be expanded, which is convenient for placing the bedpan, and the distance between the bedpan and the toilet mouth is more reasonable, and it is not easy to cause The patient's excrement splashes and other problems, and it is convenient and hygienic to use.
