Description

DETAILED DESCRIPTION OF THE INVENTION (a) Object of the Invention Industrial Application Field The present invention is used for defecation of people who are unable to live, such as critically ill patients or senile patients, and is suitable for use in hospitals and nursing homes.

BACKGROUND ART Conventionally, various types of vacuum pumps that force suction, and those that utilize gravity are known.

Problems to be Solved by the Invention Vacuum type pumps have a limited suction power because they use vacuum pressure, and if a strong suction power is to be obtained, the pump will become larger and the cost will increase. Therefore, when a small-sized device is used, the suction of feces is insufficient, and the pipes are clogged with feces, making post-treatment very troublesome.

Additionally, gravity-type toilets require the toilet to be located at a high location, and are suitable for Western-style beds, but cannot be used for Japanese-style beds.

The present invention aims to provide a defecation device that uses a small pump, has good defecation efficiency, effectively prevents odor leakage, and does not cause contamination of bedding due to scattering of urine, washing liquid, etc.

B. Effects of the Invention Means for Solving the Problems The present invention provides an insert-type toilet main body having a defecation opening on the upper surface and a diaphragm connected to the defecation opening, and an axial line passing through the bottom of the defecation opening. A pressure gas delivery port which opens to this defecation port and communicates with the pump's discharge port through a delivery pipe, and a defecation suction port which communicates with the pump's suction port via a defecation tank by a suction pipe, and its own axis. a drying tube that is supported by the main body so as to be able to slide freely in the direction of the toilet bowl, and whose distal end has a spout that can advance into the defecation port and whose rear end communicates with the delivery pipe via a switching valve; A liquid supply path is arranged along the main body and the outflow port is open to the defecation port, and one end is connected to the pressurized cleaning liquid supply port, and the distal end is supported by the main body so as to be slidable in the direction of its own axis. The present invention is characterized in that it has a cleaning cylinder for human body excretory part cleaning liquid, the spout of which can advance into the defecation port, and the rear end of which communicates with the liquid supply path via a switching valve.

It would be convenient to put the tank, pump, motor, etc. in one set as in the past, and make it movable by attaching wheels.

How it works: When the tip of the device is inserted under the buttocks of a person who has the urge to defecate, and the urinary comb is held tightly between the crotches, the stent will be positioned above the defecation opening. When the pump is started, pressurized gas is discharged from the discharge port through the delivery pipe, and gas is sucked from the suction port through the suction pipe. Therefore, a strong airflow is generated at the bottom of the defecation port from the outlet to the suction port. At the same time, cleaning liquid is supplied from the liquid tank by a pump or through a water tap through the liquid supply path, and the cleaning liquid flows out from the outflow hole onto the wall surface of the defecation port to wet it and prevent adhesion of defecation.

When defecation begins in this state, the stool falls towards the bottom. On the other hand, urine is similarly discharged toward the bottom, or after being discharged toward the inner wall surface of the urinary comb, it travels through the wall surface or mesh and similarly falls to the bottom. At this time, because there is a net, even if it is released with considerable force, it will not scatter outside from the sieve. When these defecations are carried by the airflow from the outlet to the suction port, they receive positive wind pressure on the outlet side and negative wind pressure on the suction port at the same time, so the defecation instantly enters the suction port. It is carried by the wind current inside the suction pipe and reaches the defecation tank. Here, gas and liquid are reliably separated as usual, feces are stored here, and only gas is pushed out again from the discharge port.

If the suction pipe that conveys feces is constricted by restricting its suction power and the diameter of the outlet to the feces tank by interposing a ring, etc., the efficiency of conveying the feces will be extremely high.

After defecating, push in the cleaning tube so that the spout at the tip advances into the defecation port, then switch the valve on the liquid supply path to supply cleaning liquid. Finish cleaning the excretory part by appropriately changing the position and direction of the spout. Even if the cleaning liquid flows down to the upper surface of the inlet edge of the suction port, the airflow at the bottom does not act on the upper surface, so the cleaning liquid will not scatter due to wind pressure, and even if it does, the screen will cover the top. Since it is attached, it will not jump out of the toilet body. After washing, the wastewater is carried by the airflow and collected in the defecation tank.

When cleaning is complete, stop the valve and pull back the cleaning cylinder to allow the spout at the tip to escape from the defecation port. Next, push the drying tube in and advance the spout into the defecation opening. When pressurized gas flows into this drying cylinder from the delivery pipe connected to the delivery port using the switching valve, it flows out from the jet port,
Quickly dry skin surfaces that have been wet by washing. Appropriately changing the position and direction of this jet port is the same as in the previous case. Once the toilet is dry, the airflow is shut off using a valve, and the toilet body is pulled out from the buttocks to complete the defecation process.

Embodiment 1 is an insert-type toilet bowl body, and the upper surface slopes downward toward the insertion side as usual. A defecation port 2 is opened in the upper surface, and a comb 3 is curved upward from the defecation port 2 toward the insertion side. This toilet 3 has an opening 4 on the insertion side, and a collar 5 facing inward is formed on both sides of the opening 4 to prevent leakage, and the opening 4 on the defecation opening 2 side allows the opposing collars 5 to approach each other slightly. It is preferable to make the tube narrower in order to prevent leakage.

By providing a net 7 on the urine receiving surface 6 of this water closet 3, it is possible to prevent urine from splashing back and scattering to the outside. In addition, when the lower end 8 of this net 7 is curved toward the defecation port 2 side to cover the upper edge 10 of the introduction path 9 to the defecation suction port 12 (described later), the cleaning liquid becomes droplets due to wind pressure and is sprayed onto the main body. It can effectively prevent the particles from scattering to the outside of 1.

11 is a pressure gas delivery port, and 12 is a defecation suction port, both of which are open to the defecation port 2 facing each other on an axis 13 passing through the bottom 2' of the defecation port 2. The delivery port 11 communicates with the discharge port 16 of the pump 15 at the other end of the delivery pipe 14, and the suction port 12
The other end of the suction pipe 17 communicates with the suction port 18 of the pump 15 via a defecation tank 19.

The diameter d of this suction port 12 is the inner diameter of the suction pipe 17.
When the diameter is smaller than d' and somewhat larger than the aperture d'' of the outlet 11, the velocity of the airflow at the suction port 12 becomes large, making it possible to remove feces very effectively.

Reference numeral 20 denotes a drying cylinder for drying the skin by supplying drying gas, and is supported by the main body 1 so as to be able to slide freely in the direction of its own axis, and the spout 21 at the tip can advance into the defecation port 2. There is. And this drying cylinder 2
The rear end of the air conditioner 0 communicates with the pressurized gas delivery pipe 14 via the switching valve 22.

This drying tube 20 is made into a cylinder, and the through hole 23 of the main body 1
When inserted loosely, the drying tube 20 can freely rotate around the axis, making it possible to widen the range of work.

Reference numeral 24 denotes a liquid supply path, which is arranged along the opening edge of the defecation port 2 of the toilet main body 1 as shown in FIG. It communicates with a pressurized supply port 26 for (water, etc.). The number of the outflow holes 25 and their arrangement at the edge of the opening are determined appropriately.

Reference numeral 27 denotes a washing cylinder for washing the excretory part of the human body with a washing liquid (water, etc.), which is supported by the main body 1 so as to be able to slide freely in the direction of its own axis, and the spout 28 at the tip can advance in relation to the defecation opening 2. It's becoming like that. A rear end portion of this cleaning cylinder 27 communicates with the liquid supply path 24 via a switching valve 29.

This cleaning cylinder 27 is a cylinder, and the through hole 30 of the main body 1
When inserted loosely, the cleaning cylinder 27 can freely rotate around the axis, making it possible to widen the working range.

In the drawings, 31 is a handle, and 32 is a wheel.

When in use, the main body 1 is inserted under the buttocks, and the hair comb 2 is held between the thighs. When the pump 15 is started and liquid is sent to the liquid supply path 24, the liquid wets the wall surface of the defecation port 2, and a high-pressure air current flows from the delivery port 11 to the suction port 12 at the bottom thereof. When the person defecates here, the feces falls directly to the bottom, is carried by the air current, and is promptly collected in the tank 19. In addition, urine may fall directly, or it may hit the urine receiving surface 6 of the urinary comb 3 and flow down this surface or through the mesh, but in both cases, it is eventually carried by the airflow and is quickly transported. is collected in tank 19.
The gas from which the excreta have been separated in the tank 19 is again pressed out from the discharge port 16 by the pump 15 and used for circulation.

After finishing using the toilet, the user pushes in the cleaning cylinder 27, cuts off the liquid supply path 24 using the switching valve 29, sends the cleaning liquid to the cleaning cylinder 27, and squirts the liquid from the spout 28 to clean the excretory area. The waste liquid flows down to the bottom and is likewise carried into the tank 19 by the air flow.

When cleaning is finished, the liquid is stopped, the cleaning cylinder 27 is pulled back, the drying cylinder 20 is pushed in, the switching valve 22 is switched, and the pressure gas is guided to the drying cylinder 20. Gas is ejected from the ejection port 21 and quickly removes water droplets adhering to the skin. Once dry, the gas is shut off using the switching valve 22 and the drying tube 20 is pulled back.

All you have to do now is pull out the main body 1 from under your butt.

Effects of the Invention According to the present invention, since the defecation opening of the toilet bowl body is made to face the pump's discharge and suction circulation system, defecation can be discharged not only by the simple suction force but also by the synergistic effect of the discharge force and the suction force. The discharge force is extremely strong, the discharge passage does not become clogged, maintenance is easy, and it can effectively prevent odors, urine, cleaning, etc. from leaking outside the main unit, and it is extremely safe. There are various features that can be used.
