Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pushing / suctioning type defecation apparatus used for defecation of persons who cannot move, such as severely ill patients and elderly people, and is suitable for installation in hospitals and nursing homes.

[0002]

2. Description of the Related Art There is a model of a pushing and suctioning type defecation apparatus [Patent No. 1586604 (Japanese Patent Publication No. 8738)] which the applicant of the present application filed earlier and made a patent.

[0003]

With this type, since the inside of the hood cannot be cleaned, not only the odor of urine leaks to the outside after use, but also the urine directly flows into the defecation chamber. Therefore, even when the device is in use, the defecation chamber and the hood can always communicate with each other, and the odor of stool may leak to the outside only by the suction force of defecation.

Further, since the cleaning of the defecation chamber is performed by causing the liquid to flow out from the outflow hole of the liquid supply passage arranged around the defecation port, it cannot be flushed on the wall surface completely, and when diarrhea occurs, the liquid is wet. There was a case where it couldn't be washed off because it stuck to a wall that wasn't there. The present invention is intended to provide a defecation device that more effectively prevents leakage of odor and keeps the wall surface of the defecation chamber clean.

[0005]

The push-type toilet body of the push-pull and suction-type defecation device of the present invention has a defecation chamber inside itself, and a defecation port of the defecation chamber is opened on the upper surface of the defecation chamber. There is a hood that communicates through a small hole in the barrier floor. The main body has a urine reservoir, a pressure gas outlet, a defecation suction port, a drying cylinder, a cleaning cylinder, an air supply port, and a cleaning port.

The urine reservoir is located below the shut-off bed and has, on the one hand, an outlet communicating with the small hole, and on the other hand having a shut-off valve which is temporarily opened by the pressure of a predetermined amount of liquid. There is. Further, the outlet for the pressurized gas is open to the defecation chamber on the one side on the axis passing through the bottom of the defecation chamber. The defecation suction port is axially opposite to the above-mentioned delivery port and opens in the defecation chamber, and the urine outflow port is also in communication with this.The suction pipe is connected to the pump suction port via the defecation tank. It is in communication.

Further, the drying cylinder and the cleaning cylinder are supported by the main body so as to be slidable in their own axial direction and rotatable about their own axes, so that the ejection port at the tip can advance into the defecation chamber. The air supply port and the cleaning port are opened downward on the inner surface of the upper part of the dust shield.

The pressure gas delivery port, the drying cylinder and the air delivery port are connected to the air delivery pipe following the pressure gas delivery port of the pump so as to be able to be shut off. The cleaning cylinder and the cleaning port are connected to the supply pipe of the pressure liquid so as to be shut off. Further, the liquid supply pipe communicates with the air supply pipe so as to be able to be shut off before the outlet for the pressurized gas. The closing tendency of the closing valve of the urine reservoir is given by its own weight and the biasing means.

[0009]

[Function] Inserting the tip of the body under the hips of a person who has a bowel movement and inserting the cloak tightly between both groins, the anus is located above the defecation opening, and the defecation room is sealed. It
When the pump is started here, the pressure gas is discharged from the discharge port through the delivery pipe, and the gas is sucked through the suction pipe through the suction port. Therefore, a strong airflow is generated from the delivery port to the suction port at the bottom of the defecation chamber. At the same time, the pressure liquid is supplied from the liquid tank to the air supply pipe through the liquid supply pipe and the valve through the pump or the tap, and it is atomized with the gas from the outlet into the defecation chamber to wet the wall surface. While flowing down, prevent defecation from adhering. This pressure liquid may be sent simultaneously to the cleaning port of the hood.

When defecation starts in this state, the stool drops toward the bottom. On the other hand, urine is similarly discharged toward the bottom, or is discharged toward the inner wall of the hood and then flows down through the wall or net to the bottom in the same way, and passes through the small holes in the barrier floor to collect urine. to go into. Then, when the amount of urine reaches a certain amount, the closing valve is pushed open by the pressure, flows out from the outflow port, enters the suction pipe, and is sucked into the defecation tank.

On the other hand, when stool falls and is placed in the air flow from the delivery port toward the suction port, a positive wind pressure is applied to the delivery port side and a negative wind pressure is simultaneously applied to the suction port side, so that defecation is sprayed and washed. With the liquid for use, it instantly enters the suction port, is transported by the air flow in the suction pipe, and reaches the defecation tank. Here, as usual, gas and liquid are surely separated, defecation is stored here, and only gas is pushed out again from the discharge port.

After the defecation is completed, the washing cylinder is pushed in and the ejection port at the tip is advanced to the center of the defecation chamber. Then, the valve of the liquid supply path is switched to supply the cleaning liquid to the cleaning port of the cleaning cylinder and the concealer. If the cleaning liquid is supplied to the cleaning port from the front, of course, it is not necessary. In the case of a cleaning cylinder, the excretion part is cleaned while changing the position and direction of the spout appropriately.

Even if the cleaning liquid flows down to the upper surface of the introduction edge portion of the suction port, the air flow at the bottom does not act on the upper surface of the defecation chamber, so that the cleaning liquid is not scattered by wind pressure. In the case of the sterilizer, the washing liquid flows down from the washing port along the inner wall surface and the net to wash them, and then flows into the urine reservoir through the small holes in the blocking floor. Then, when the amount of waste water in the urine reservoir reaches a certain amount, the closing valve is pushed open by the pressure and flows from the outflow port to the suction pipe.
Then, the waste water that has been washed is conveyed to the air flow and collected in the defecation tank.

When the washing is completed, the valve is closed, the washing cylinder is pulled back, and the ejection port at the tip end is made to escape from the defecation chamber. Next, the drying cylinder is pushed in, and its ejection port is advanced into the defecation chamber. The valve is operated to allow the pressure gas to flow from the delivery pipe connected to the delivery port to the air delivery port of the drying cylinder and the screen. The gas flowing out from the ejection port of the drying cylinder quickly dries the wet skin surface by washing. Properly changing the position and direction of the jet port is the same as in the previous case. In addition, the gas flowing out from the air supply port dries the inner wall surface of the dust shield and the net. When dry, shut off the air flow with a valve, pull out the toilet bowl from the bottom, and finish the series of defecation.
