Of these, the wash water jet nozzle 27 located at the upper side is for a female and jets wash water that spreads in a fan shape in the vertical plane from the upper part of the urethral opening to the lower part of the urethral opening. The fan-shaped jet spread angle for women varies depending on the jetting pressure and jetting amount of the cleaning liquid, but is about 60 ° to 100 °. On the other hand, the flushing water spray nozzle 28 located at the lower level is for men and is directed toward the anus, but it sprays linearly with little spray spread.

A warm water supply mechanism for cleaning water ejected from the cleaning water ejection nozzle will be described with reference to FIG. In FIG. 9, the tip of the cleaning hose 8 is connected to either one of the connection ports 27b and 28b of the cleaning water jet nozzles 27 and 28 (set in advance according to the sex of the patient to be used, and the connection of the unused one). The mouth is covered with a cap (not shown), and the rear end of the cleaning hose 8 communicates with the level of the cleaning water in the cleaning water tank 7. The wash water purification tank 7 has a heater at the bottom and functions as a hot water tank.

Further, an exhaust pipe 62 of the vacuum pump 6 is connected above the surface of the cleaning water in the cleaning water tank 7 as a supply pressure source of the cleaning water, and the exhaust pipe 62 is connected to the first opening / closing valve 63. The hot water in the wash water tank 7 is discharged to the wash hose 8 by the exhaust pressure of the vacuum pump 6 given via the. That is, the vacuum pump 6 functions as a water supply pump, and the cleaning water stored in the cleaning water tank 7 is ejected from the cleaning water ejection nozzles 27 and 28.

In this embodiment, the exhaust pipe 62 is provided with an open pipe 65 via an open / close valve 64. Therefore, even when the on-off valve 63 is operated so as not to eject the washing water and the exhaust pipe 62 is closed, the exhaust gas is discharged through the on-off valve 64 and the open pipe 65, and the vacuum pump 6 is normally operated. Can be driven. Further, the cleaning hose 8 is provided with a second opening / closing valve 71. By closing the second opening / closing valve 71, it is possible to stop the supply of the cleaning water and pressurize the cleaning water tank 7. There is.

Next, the dirt suction mechanism will be described with reference to FIGS. 2, 3 and 9. The front end of the waste hose 3 is connected to the waste suction port 26, and the rear end of the waste hose 3 is connected to the waste tank 5 via a large-diameter first pinch valve 41 described later. Then, as shown in FIG. 12, a vacuum pump 6 functioning as a suction pump is connected to the waste tank 5 by a connecting pipe 61.

The pinch valve unit 4 has a large-diameter first pinch valve 41 interposed between the waste hose 3 and the waste tank 5 and residual water in the waste hose 3 in the middle of the waste hose 3. The second pinch valve 45 having a small diameter for sucking from the residual water suction pipe 30 provided in the through the residual water suction tube 31. Further, the pinch valves 41 and 45 are configured to open and close the passages of the waste hose 3 and the residual water suction tube 31 by operating the control valves 480 and 490.

The controller 90 shown in FIG. 9 opens the opening / closing valve 71 before use to supply cleaning water from the nozzle 27 to the reservoir 23 and closes the bottom communication port 23a with the cleaning water. After that, the pinch valve 41 is opened to constitute a control means for sucking the dirt in the reservoir 23, which is composed of washing water and excrement, into the dirt tank 5 from the dirt suction port 23a.

Next, the operation of the above configuration will be described step by step with reference to FIG. (1) Closure of Bottom Communication Port 23a by Stored Water First, washing water is supplied into the storage part 23 of the cup unit 2 and the inside of the storage part 23 is closed to a level where the bottom communication port 24 at the lower rear end is blocked. Fulfill. This is done as follows.

By pressing the “start operation” button of the remote controller 10, the pinch valves 41 and 45 are “closed” (the control valves 480 and 490 are “open”), the first opening / closing valve 63 and the second opening / closing valve 71 are opened. The vacuum pump 6 is driven in the "open" state. Since the exhaust pressure of the vacuum pump 6 is sent to the wash water tank 7, the pressure in the wash water tank 7 is increased, and the wash water (warm water) in the wash water tank 7 is connected to the wash hose 8 by the pressure. The cleaning water jet nozzle (in the present embodiment, the female washing water jet nozzle 27) flows out. Therefore, the cleaning water jet nozzle 27 functions here as a water supply port for the reservoir 23.

When a predetermined amount of cleaning water is stored in the storage portion 23 of the cup unit 2 and the bottom communication port 24 is blocked by the stored water, the second opening / closing valve 71 is closed. Therefore, by closing the second opening / closing valve 71, the supply of washing water is stopped and the inside of the washing water tank 7 is pressurized to a predetermined pressure slightly higher than that.

(2) Washing After excreting, the second opening / closing valve 71 is opened again by pressing the “Washing start” button on the remote controller 10, and the wash water (warm water in the wash water tank 7 is heated by the above-mentioned predetermined high pressure. ) Is sent to the washing hose 8 and is jetted vigorously from the washing water jet nozzle 27 for women. As described with reference to FIG. 8, this jet of wash water becomes warm water that spreads flatly and in a fan shape in the vertical plane from the upper part of the urethral opening to the lower part of the urethral opening, thus washing the crotch extensively, It can be widely washed from the female urethral meatus to the anus. Therefore, compared to the type in which the wash water is allowed to flow down from above, the contaminated wash water after washing does not reach the urethral meatus, etc., and therefore Escherichia coli etc. enter the urethral meatus, etc. It is possible to prevent the inconvenience of the onset of the above.

(3) Suction with the dirt hose This is because after the above cleaning, by pressing the “suction start” button of the remote control 10, the dirt hose 3 is sucked and the residual water suction tube 3 that follows is sucked. Residual water suction by 1.

First, of the control valves 480, 490, in the space up to the bottom communication port 23 a of the storage section 23, which is closed by the waste hose 3, the wash water and the waste that is discharged by operating the control valve 480. Suddenly becomes a negative pressure, and a large negative pressure is temporarily applied to the filth, so that the filth is completely sucked from the storage section 23.

At this time, the concave chamber 22 of the cup unit is continuous from the upper portion of the inner surface to the lower portion of the inner surface by the passage 29 of the handle 24 and communicates with the atmosphere, so that the concave chamber 22 is extremely sucked when sucking filth. There is no danger of negative pressure. In addition, since the sick person can always remove the cup unit from the crotch area by himself, the sense of danger due to suction can be completely eliminated.

Next, in order to remove the residual water remaining in the waste hose 3, the control valves 480 and 490 are opened and the degree of vacuum in the waste tank 5 is increased, and then the control valve 490 is operated. The joint portion of the residual water suction tube 31 is open to the bottom surface or the lower portion of the residual water suction tube 30 and is configured so that even the lowest level residual water in the tube is blocked by this. The inside of the space up to the opening of the residual water suction pipe 30, which is blocked by the residual water, becomes a negative pressure at once, and the residual water is completely sucked and removed by the large negative pressure. The negative pressure generated at this time also communicates with the atmosphere via the passage 29, as described above, and prevents the inner cover 2b from adsorbing.

In the above embodiment, the passage is formed as an air introduction hole, but the air introduction hole is not limited to this, and one or a plurality of holes may be provided in other portions of the cup unit. It may be. Further, the check valve is not limited to the configuration of the embodiment and may have an appropriate configuration.
