SUMMARY OF THE INVENTION
No. 17 pants are formed by an air bladder belt that hits the thighs, waist, lower abdomen, and buttocks of the human body to form a sealing levee and spill out excrement, and warm water and warm air flow inside the enclosure surrounded by the sealing ridge. Washing and drying are performed, and excrement and washing liquid flow down from the outlet facing the buttocks to a drainage reservoir provided immediately below by their own weight and are collected. In the above configuration, wastewater such as excrement and washing liquid is drained and temporarily accumulates in the pants, so that the patient cannot be used in a horizontal position. Therefore, the patient may have a bedsore. In addition, since the excrement is drained off, the outlet may be clogged. In addition, since the supply of hot water and hot air needs to be performed by the caregiver turning the supply switch ON / OFF, it is necessary that the caregiver be completely attached to the caregiver. Such operations are often impossible for severely ill patients.

A diaper disclosed in Japanese Patent Application Laid-Open No. Hei 6-237953 discloses a diaper in which compressed air is supplied to air bags provided around the waist and the thigh to make the air bag adhere to the wearer, and after supplying hot water for washing, the warm air is washed. Supply air and dry. Further, when hot water is injected, a negative pressure is applied to the discharge port, and sewage is collected from the suction port into the toilet tank. In the above configuration, since the hot water / hot air discharge port is provided above the lower abdomen of the wearer, it is possible to wash from a site far away from the local area, and it is doubtful whether a sufficient cleaning effect can be obtained. Also,
Since the suction port is formed with a large number of holes, clogging is likely to occur due to excrement, and a tube for supplying compressed air or hot water / hot air and a discharge tube are connected to a female connector provided on the side of the diaper. It is provided to be detachable via a mold connector. Therefore, it is impossible to turn over while the tube is connected to the diaper, and even if the tube is removed, it is difficult because the connector portion has an uncomfortable feeling.

In the excrement disposal apparatus disclosed in Japanese Patent Application Laid-Open No. 10-272150, a plastic undergarment having a water supply channel formed therein and a discharge hole or an outflow groove formed on a mounting surface side is mounted on the body.

Then, the discharge of excrement by the suction device and the injection of hot water by the water heater are performed in parallel, and the underwear and the body are washed. After the washing, the air is blown by the suction device to dry the underwear and the body. Further, the excrement collected by the discharge hose is separated into air and other excrement by a separator to be collected. According to the above configuration, the underwear is made of plastic and is always in close contact with the body, so that the underwear is not only comfortable to wear, but also the air permeability may be poor. In addition, since a discharge hose, a supply pipe, and the like are inserted into the underwear from the outside, they become obstructive and do not turn over, so that bedsores are likely to occur. Further, it is not known whether the structure of the discharge hose or the feed pipe inserted into the underwear is maintained or not.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a diaper which is comfortable to wear and does not restrict the degree of freedom of the body and a connection hose connected to the diaper. It is another object of the present invention to provide an automatic excrement processing apparatus that automatically reduces the caregiver's care load by automatically processing the excrement excreted in the diaper, and also enables the caregiver to always save time and effort.

Prior to the activation of the vacuum pump 51 and the cleaning pump 52, it is preferable that the melody be flown by the notification unit 53 to notify the user of the treatment of the excrement. The drying inside the diaper body 2 is as follows.
This is performed by switching the air supply passage of the blower 50 from the air passage to the washing and drying passage. Alternatively, air for drying may be pressure-fed by a pump for washing, and a blower for drying may be provided exclusively. After the drying is completed, the air is removed from the main-body-side inflatable section 5 and the sealing inflatable section 6, and the state returns to the normal cloth diaper 1 mounting state.

Here, the excrement processing operation of the diaper apparatus for automatic excrement processing described above will be described. The diaper 1 is worn on a bedridden elderly person or a sick person. The binding margin 2b on both sides of the diaper main body 2 can be opened and closed by a hook-and-loop fastener, and the degree of tightening can be adjusted by the index 14. At this time, the connection hose 4 may be connected to the diaper main body 2 or may be connected later. Further, the diaper main body 2 is of a front opening / closing type, but may be of a pants type. The diaper body 2 and the connection hose 4 allow internal moisture to escape to the outside, but are made of a breathable cloth that does not take in external moisture, so that they are comfortable to wear and remain deflated when no fluid is pumped. 4 does not get in the way, it can freely turn over and raise the upper body, and the body has a high degree of freedom, so that bedsores and the like hardly occur.

Next, when there is excrement such as defecation and urination in the diaper 1, the excrement sensor 49 detects the odor and the degree of wetting, and when a detection signal is input to the control unit 47 of the excrement processing apparatus 3, The notification unit 53 gives a notice of the excrement disposal by melody. Then, by operating the blower 50, air is pressure-fed to the diaper main body 2 through the air supply pipe passage 40 and the air passage portion 21 of the connection hose 4 to expand the main body side expansion portion 5 and the sealing expansion portion 6. While opening the leg while pressing the waist and both thighs to form a closed space inside,
The inflation portion 7 is inflated to lift the buttocks 13 to form a washing space. At this time, the air passage 21 in the outer wall of the connection hose 4 expands, and then the hose joint 1
Since the second airbag 19 is inflated and the connection portion is pressed in the radial direction, the sealing property between the hose joint portion 12 and the connection hose 4 is maintained well.

Then, the suction operation of the excrement is started by the vacuum pump 51, and the excrement is discharged from the discharge port 11 through the suction passage 28.
And is collected in the collection tank 46 via the suction pipe 42 in the excrement disposal apparatus 3. Further, the cleaning pump 52 is operated, and the cleaning / drying passage of the diaper main body 2 is supplied to the cleaning space including the inside and the local portion of the diaper main body 2 via the fluid supply piping 41 and the cleaning / drying passage 22 of the connection hose 4. A cleaning liquid such as hot water is pressure-fed to the part 9 to be jetted radially from the jet holes 10 to wash the inside of the diaper main body 2 and a local part for a predetermined time. Further, the cleaning liquid is caused to flow out of an outflow hole 22a provided in the cleaning / drying passage portion 22 of the connection hose 4, so that no dirt remains on the inner wall of the hose.

When the cleaning operation is completed, the air supply path of the blower 50 is switched from the air supply pipe 40 to the fluid supply pipe 41, and the diaper main body 2 is connected via the washing / drying passage 22 of the connection hose 4. The washing space in the diaper main body 2 is dried for a certain period of time by blowing out hot air from the ejection holes 10 provided in the washing / drying passage 9. When the drying operation ends, the blower 50 is stopped, and the suction operation ends. Then, the air in the main-body-side inflatable portion 5 and the sealing inflatable portion 6 of the diaper main body 2 is evacuated, thereby completing one cycle of excrement suction / removal operation.

According to the above configuration, the diaper 1 and the connection hose 4 for connecting the diaper 1 and the excrement disposal device 3 are formed by superposing a water-resistant cloth on the inside of the diaper main body 2 during excretion. The air is pressure-fed to the fluid passage portion via the connection hose 4 to form a sealed space, so that the diaper made of a non-reversible cloth diaper that normally releases internal moisture to the outside and does not take in external moisture during normal mounting. Since the comfort is good and the connecting hose 4 is not in the way, the connecting hose 4 can be turned over and the upper body can be raised, the freedom of the body is not restricted, and the bedsore is unlikely to occur. Also,
When there is excretion in the diaper 1, air is pressure-fed from the excrement disposal device 3 to the main body-side inflating section 5, and the diaper main body 2 is inflated, and the sealing inflating section 6 is inflated, so that the waist circumference and both thighs are expanded. The vicinity of the hole 2a into which the part is inserted is sealed to form a sealed space inside, and the inflation portion 7 for lift is inflated to form a washing space between the buttocks 13 and the diaper main body 2; The hot water or hot air pumped from the excrement disposal device 3 is blown into the closed space from the washing / drying passage 9 provided between the seal 5 and the sealing expansion portion 6, so that the excrement is sucked and removed.

According to the present invention, a diaper and a connecting hose for suction are formed by laminating water-resistant cloths in multiple layers, and fluid passage portions formed in the diaper main body and the connecting hose during excretion communicate with each other. Air is pumped through to form a sealed space inside the diaper body, so when wearing it normally, internal moisture escapes to the outside and irreversible cloth diapers that do not take in external moisture make it comfortable to wear In addition, since the connecting hose is not in the way, it can be rolled over and raised, and the freedom of the body is not restricted, and bedsores are unlikely to occur. In addition, when excretion is present in the diaper, air is pressure-fed from the excrement disposal device to the main body-side inflating section to inflate the diaper main body, expand the sealing inflating section, and insert the waist portion and both thighs. Seals the vicinity of the hole to form a sealed space inside, and expands the inflating portion for lift to form a washing space between the buttocks and the diaper main body, between the main body side inflating portion and the sealing inflating portion. The washing liquid or warm air blown from the excrement disposal device is blown into the enclosed space from the washing and drying passage provided in the toilet, so that the suction and removal of excrement and the washing and drying operation are automatically performed continuously. As well as reducing the caregiver's care burden,
It is also possible to eliminate the need for the caregiver to always attend. In addition, on the inner layer side of the diaper main body, there are provided an inflation part for lift that forms a washing space between the buttocks and the diaper main body, and an inflation part for leg opening that expands so that both groin parts are pushed outward. In this case, a cleansing space is reliably formed between the buttocks and the diaper main body, and a local part which is difficult to clean can be easily and effectively cleaned and dried, and a good hygiene condition can be maintained. In addition, a soft hose joint is formed at the outlet of the diaper body, and the inner wall of the connecting hose and the outer wall of the hose joint are connected by a concave and convex fitting having a tapered surface, and the expansion of the connecting hose is performed. When the fitting portion is nipped by the pressure and the expansion pressure on the hose joint side, and the fluid passage portions communicate with each other, the sealability between the diaper main body and the connection hose can be maintained well.
