Description

  The present invention relates to an excrement disposal apparatus for a care recipient and a method thereof. More specifically, the present invention relates to an elderly person living alone who is unable to urinate or defecate alone or a severe care recipient who is unable to move. , Automatically handle urination and defecation to keep care recipients clean, reduce discomfort, and reduce the labor for emergency care agencies, nurses, family members, etc. The present invention relates to an excrement disposal apparatus and method for reducing the need for the above.

According to a 2011 survey, it was said that 4.6 million people were living alone. Not all elderly people living alone need an automatic waste disposal device. Patients in care facilities and bedridden elderly care recipients need an excrement disposal device that automatically detects and processes urination and defecation and keeps the crotch of the care recipient always clean.
The urine of bedridden patients in nursing homes and hospitals is processed in a spilled state through a tube through the urethra, and the stool is defecate to a diaper, and the caregiver replaces the diaper to keep it clean. Currently. Although there are few problems at facilities with veteran caregivers, such as hospitals and nursing homes, many people feel uncomfortable with having others take care of them.

In recent years in Japan and Europe and the United States, with the declining birthrate and aging of the population, there is a problem of physical and mental fatigue to caregivers, such as the shortage of caregivers, the heavy burden on cohabitants, and elderly care where the elderly care for the elderly. The number of cases that sometimes become miserable is increasing, and the development of an excrement disposal device has become an urgent task.
There have been many patent applications in this field related to bedridden care recipients. However, in reality, for care recipients, it has not been able to demonstrate superiority compared to ordinary diapers in terms of wearing comfort, cleanliness, pressure ulcers, device defects, maintainability, etc. It is.

Conventional excrement disposal apparatuses include those described in Patent Documents 1, 2, and 3.
The invention described in Patent Literature 1 is an automatic excrement disposal apparatus for bedridden elderly people, and includes a waste tank, a suction device, a cleaning device, a diaper cup, and the like. However, the apparatus according to the present invention hardly mentions major problems associated with this type of excrement disposal apparatus such as noise, vibration, sterilization, motor overheating, patient comfort, and apparatus maintainability.

  The invention described in Patent Document 2 is a method in which an adhesive is applied to the periphery of the attachment hole in order to attach the periphery of the attachment hole of the diaper to the cup.

Is sucked into the sewage tank 22 and stored. In the sewage tank 22, the aspirated excrement and the washed sewage are separated by gravity by the work wind circulating through the suction circulation pipe 50.

When the suction motor 31 is operated, the waste receiving recess 77 of the diaper cup body 10 reaches the suction motor 31 via the filth suction hose 15, the sewage tank unit 22, and the purification processing unit 23, and further suction circulation. Through the pipe 50 and the return air hose 18, a flow of air that is returned to the inside of the diaper cup body 10 and circulated is generated.
When the suction motor 31 is operated, the work air in the suction circulation pipe 50 introduced from the suction port of the suction motor 31 is absorbed by passing through the suction motor 31, and the return air cooler 26 is discharged from the discharge port of the suction motor 31. , Flows out from the return air hose 18 into the diaper cup body 10 via the return box unit 27.

Further, about 10% of the work air sucked by the suction motor 31 is discharged from the return box unit 27 through the partial discharge hose 19, and the remaining 90% is discharged from the return box 27 via the return air hose 18. Return to the diaper cup body 10 from the air outlet. That is, air is sucked through the gap between the diaper 54 and the buttock of the diaper cup body 10 attached to the care recipient, and the air that is almost the same amount as the sucked air (about 10% of the work wind) is returned. A part of the hose 19 is discharged from the box 27 to the outside air.
In this way, warm air is blown into the diaper cup body 10 through the return air hose 18.
In order to prevent the suction motor 31 from being heated, the cooling fan 32 of the suction motor unit 24 sucks cooling air from the cooling air intake 34 through the filter 33 and cools the suction motor 31 to cool it. It is discharged from the wind outlet 35.
Therefore, comfortable cleaning can be performed in a state where warm air is present around the waistline of the care recipient.

The overall schematic operation of the above configuration will be described. Detailed processing operation for each mode based on the flowcharts of FIGS. 8 to 11 will be described later.
First, the hot water tank 38 is filled and it is confirmed whether the sewage tank 22 is empty. When the hot water tank 38 is empty or the sewage tank 22 is full, the processing operation permission is NO, an alarm is displayed by a signal from the water level sensor 42 or the water level sensor 58, and the automatic operation state is not entered.
The diaper cup main body 10 is mounted through the diaper 54 from the buttocks of the care recipient to the crotch, and the start switch of the control panel unit 56 is turned on. In this state, the sensors (the water level sensor 41, the water level sensor 42, the temperature sensor 43, the heater 44, the temperature sensor 45, the temperature sensor 49, the negative pressure sensor 52, the bimetal 57, the water level sensor 58) can be processed and operated in a normal state. State. Further, when the suction motor 31 is not operated, the light wind motor 48 is operated, and is sucked from the diaper cup body 10 through the light wind hose 16 and the light wind circulation pipe 51 to the light wind motor 48. 1 and 2, a breeze is sent as shown by the dotted line in FIG. 1 and FIG. 2, and sent into the diaper cup body 10 from the return air outlets 75 a and 75 b. When the suction motor 31 is inactive, the light wind motor 48 may be continuously operated, or may be intermittently operated for a predetermined time in order to suppress the internal temperature rise and save power. Details will be described later with reference to FIG.

Here, when excrement is detected by any one of the stool sensor 13, the urine sensor 14, and the odor sensor 80, hot water is sent from the washing water unit 25 to the diaper cup body 10 through the washing water hose 20 after a predetermined time has elapsed. It is. The washing water unit 25 includes a warm water tank 38 including a heater 44 and a temperature sensor 43 so that the warm water is kept at an appropriate temperature for the human body.
Warm water is sprayed and washed from the pubic washing water discharge port 76a of the diaper cup body 10 to the genital region, warm water is jetted and washed from the anal washing water discharge port 76b to the anus, and hot water is supplied from the cup washing water discharge port 76c to the excreta receiving recess 77. The excrement is washed by spraying, and the washed sewage and excrement are guided to the filth discharge port 74.

At the same time, when the suction motor 31 is operated to suck air from the suction circulation pipe 50, the sewage and excrement after washing are sucked into the sewage tank unit 22 from the sewage discharge port 74 through the sewage suction hose 15. When air is sucked from the inside of the sewage tank 22, the suctioned waste and sewage are gravity-separated by the work wind circulating through the suction circulation pipe 50 inside the sewage tank 22.
Here, the suction force of the suction motor 31 is set by the control panel unit 56 according to the values detected by the stool sensor 13 and the urine sensor 14. The output of the suction motor 31 is 400 W to 1 kW and is generally adjusted to large, medium, and small.

  The sewage tank 22 has a water level sensor 58 which is a limit sensor for the amount of filth. When the limit line of the filth tank 22 is reached, the signal is sent to the control panel unit 56 and a warning is displayed on a display board (not shown). At the same time, the nurse or nurse is contacted by telephone or wireless telephone. The sewage tank 22 separates solid filth, sewage and air.
