Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toilet bowl that allows a patient to relieve himself while lying on a bed.

Patients who cannot go to the toilet by themselves usually use a potty or a diaper, but when using a potty, a nurse's help is required before and after using the potty. In the case of "diapers", the waste remains on the patient until it is disposed of by a nurse, so it is highly aversive to conscious patients, and it is difficult to dispose of it in unconscious patients. This can result in a delay in skin treatment, which can cause damage to the skin, and in both cases, patients and nurses experience considerable hardship.

The present invention uses a negative pressure generating device that can suck both solid and liquid materials using the principle of a commercially available wet and dry vacuum cleaner as a toilet bowl, and a specially designed toilet receiver. Therefore, the object of the present invention is to provide a toilet that allows a patient to defecate while lying down, automatically disposes and cleans the filth, and does not require any human intervention during this process.

The present invention will be explained below based on the illustrated embodiments. Fig. 1 is an overall view of the toilet bowl of the present invention, Fig. 2 is a usage situation diagram of the present invention, Fig. 3 is another embodiment of the toilet receptacle and suction rim, and Fig. 4 is a sectional view of the negative pressure generator. It is.

Reference numeral 1 denotes a toilet receptacle, the main body of which is a container made of rubber or plastic having appropriate elasticity to the extent that it will not be crushed by the negative pressure of the negative pressure generating device. An airtight and flexible suction edge 2 is removably attached to the periphery of the toilet receiver, and a cleaning nozzle 3 is installed inside. The bottom of the toilet bowl is shaped like a funnel and is connected to a filth suction hose 4, and the cleaning nozzle 3 is connected to a hose 5. The filth suction hose 4 is connected to a negative pressure generator 6. The negative pressure generator 6 has a window 7 for adjusting suction pressure. A discharge hose 9 is connected to the bottom of the tank via an on-off valve 8, and the discharge hose 9 is connected to a sewage pipe. A hot water pump 10 and a hot air dryer 11 are connected to the hose 5, and an automatic switching valve 12 is provided at the connection part of the hose 5. hot water tank 1
3 is equipped with a heater with a thermostat,
Equipped with an automatic water supply valve. The structure of the negative pressure generating device is as shown in the cross-sectional view in Fig. 4.A motor 20 and a fan 21 are located at the top of the device, and an inlet 19 for cooling the motor and an inlet 4 for air containing sewage.
Since it is in a separate system, there is no risk of water being sucked into the motor. Further, when the liquid level in the tank rises or the device falls over, the float 22 closes the air inlet of the fan 21, so the fan does not suck in water. Due to the above structure, it is possible to suction both urine and urine.

The toilet bowl body is placed under the patient's bed as shown in FIG. 2, and the discharge hose 9, water supply pipe and power supply are connected. The filth suction hose 4 and the hose 5 pass through a hole provided under the patient's anus in the bed, and are connected to the toilet receptacle 1.
leading to. Place the toilet receiver against the patient's crotch as shown in the diagram.
The ``diaper cover'' 15 is attached so that the suction edge makes soft contact with the patient's crotch skin, but depending on the patient, it may be effective to use an air pillow type toilet bowl as the suction edge as shown in FIG. 3.

When the patient is conscious and able to operate the toilet by himself, he operates it using 14 operation switches. If the operation of the negative pressure generator 6 is started by 14a before starting to use the toilet, the suction edge 2 which is in a soft contact state
adsorbs to the patient's groin skin, creating a nearly airtight state. In this state, excrete any urine or urine, and then
When the hot water pump is operated by 4b, hot water is ejected from the cleaning nozzle 3 to clean the private parts. The filth is carried along with the cleaning water through the suction hose 4 into the tank of the negative pressure generator. While the negative pressure generator is in operation, the valve 8 at the bottom of the tank is closed, so filth remains in the tank. When the hot water pump is stopped and the dryer 11 is operated by the switch 14c, the valve 12 is automatically switched and warm air is blown out from the nozzle 3, and this air is also sucked and discharged. Thereafter, when the operation of the negative pressure generator is stopped, the valve 8 at the bottom of the tank is opened by the water pressure of the waste water, and the waste water is discharged through the discharge hose 9 to the sewer pipe.

If the patient is unable to press the switch on their own, a moisture sensor can be attached to the toilet receiver to detect when the patient has started defecating, and to control subsequent operations at appropriately set time intervals. It is also possible to make the process proceed automatically, or to perform intermittent operation using a time switch with preset time intervals.

The suction edge gets dirty relatively easily, so remove it and clean it from time to time. In addition, since the suction edge only lightly contacts the patient's skin except when using the toilet, there is no risk of damaging the skin or causing internal swelling.

The toilet bowl according to the present invention has the above-described configuration, and defecation, washing, and drying are all performed inside the toilet bowl. The inside of the toilet receiver is under negative pressure due to the suction power of the negative pressure generator, so even if there is a slight gap around the suction rim, the air in that area will still flow inward and the sewage will not drain. It will not spill out and stain bedding or leak odors. Since there is no risk of dirty water leaking, sufficient hot water can be used for washing and the patient can be kept clean. Since there is no need to use paper or the like, it is also suitable for people suffering from hemorrhoids. If the suction pressure inside the toilet holder is too strong, it is harmful to the patient, but this can be adjusted as appropriate by adjusting the opening area of the suction pressure adjustment window 7. Appropriate suction force applied to the anal region also has the effect of promoting pleasurable defecation.

As described above, according to the present invention, the disposal of feces, which is the most troublesome and difficult problem for patients and nurses, can be done at the same time as excretion, without having to involve anyone, and in a way that can be seen by anyone. Since it is carried out in an extremely hygienic manner without leaking any odor at all, we are confident that it will be able to greatly alleviate the labor of families and hospitals who are tired of caring for bedridden patients.
