technical field

The invention relates to an automatic defecating and cleaning device for a nursing bed, which belongs to the field of nursing beds.

Background technique

Most of the current nursing beds have the function of assisting in changing the body position, but the number of nursing beds with auxiliary stool cleaning devices is still very small. And most of the existing nursing bed toilet receiving devices can only complete simple toilet receiving work, and follow-up cleaning, dirt treatment and other work also need special nursing staff to complete. The patient cannot complete defecation independently, which brings inconvenience to use and increases the burden of nursing care.

Therefore, a new technical solution is needed to solve the above problems.

Preferably, the hot water pipe is U-shaped, that is, the hot water pipe protrudes toward the bed board.

In the present invention, the stool receiving system adopts a bedpan instead of a defecation box with a storage function, and the bedpan is externally connected with an automatic water tank and a sewage pipe. The automatic water tank can complete automatic flushing and water filling, and the sewage pipe can directly discharge the sewage into the outside world. Since the waste is not stored in the defecation box, it is not necessary for the nursing staff to perform secondary treatment on the waste, which realizes complete automation. The cleaning system is composed of a cleaning basin, a hot air blower, and a hot water device. The cleaning basin is respectively connected to the hot air blower and the hot water device through a two-position three-way solenoid valve. The hot water device and the hot air device only need to pass through a cleaning basin to clean and dry the user's body parts, and do not need two sets of independent mechanisms (cleaning and drying), so the structure is simple and practical. The cleaning basin is composed of two parts, the inner shell and the outer shell, so the bottom of the cleaning basin can have a drain hole. Since there is a drain hole at the bottom of the cleaning basin, the sewage from cleaning and flushing can be directly discharged into the external sewage pipe through the drain hole. After the body is cleaned by the simple rain shower head, the sewage needs to be treated twice by the nursing staff, which increases the nursing burden. This structure can realize the complete automation of cleaning. The hot water device consists of an external water source, an instant faucet, a drain valve, and an increasing pump. Since there is no water tank in the hot water device, there is no need for nursing staff to manually add water, which can realize complete automation. And there is a drain valve in the structure to release the cold water remaining in the pipeline to the outside, which ensures that the body is warm water every time it is cleaned, and avoids the discomfort caused by the cold water remaining in the pipeline to the body. The driving mechanism of the bedpan and the cleaning basin is composed of a single rocker double slider mechanism. Only one driving part is needed to simultaneously drive two executive components, and ensure the synchronous operation of the two executive components, the structure is simple and practical, and the efficiency is high. The bedpan slides in the slide rail under the bed board, and the top of the bedpan is close to the bottom of the bed board. Because the bedpan does not store dirt like a defecation box, the dirt in the bedpan will be flushed into the external dirt pipe after each defecation, and the bedpan will move out of the position where the bed board is connected to the toilet hole after defecation. To the sealing effect, so the odor is small, the care environment is better.

Beneficial effects: Compared with the prior art, after adopting such a structure, the present invention can realize the functions of automatic defecation and flushing through the automatic water tank, the bedpan and the driving mechanism. The user's body parts can be automatically washed and dried through the hot water device, the hot air device and the cleaning basin. In addition, each mechanism and electrical components can be controlled by PLC to realize one-button nursing care, which can facilitate patients to move on their own without the care of medical staff.
