DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for sucking and transporting human waste under negative pressure.

[0002]

2. Description of the Related Art For example, when a caretaker such as a bedridden sick person or an elderly person needs assistance, a caregiver such as a nurse lifts the waist and inserts a toilet bowl or urinal bottle between the buttocks and the bedding. After the addition, the local area is cleaned, and the toilet and the urine bottle that has been added are taken out, and the urine and the like stored in the urinal and the urinal bottle are flowed to a treatment plant (sewer). Are known.

[0003]

However, such human waste treatment requires a great deal of time for one caregiver, and because of the shortage of caregivers such as nurses in recent years, only those who need care can be turned on a regular basis. In the meantime, there was a problem that the human waste had to wear a "diaper" which easily causes rash and rash.

[0004] In addition, the use of a urinal is not only easy to notice because the odor is easily spread around the urine, but also to prevent the caregiver from applying the urinal to a local area so that it does not spill. Since the patient is required to be careful while watching, it may lead to complications of other diseases such as cystitis due to refusal to urinate due to mental stress such as shame.

[0005] When cystitis or the like occurs due to refusal to urinate, not only refusal of urination due to mental stress such as a feeling of shame as described above, but also when urinating during congestion on a highway, etc. May occur physically.

In addition, in the case of a supplement using a urinal, since the excreted urine is stored in the urinal, the volume must be made sufficiently large, and as a result, the urinal is large in size. There is a problem that not only is it difficult to handle, but also the handling is troublesome and the storage after use is bulky.

[0007] In addition, when cleaning a used urinal, the urinal is a large container. Therefore, a cleaning tool such as a brush must be inserted from the entrance of the urinal to clean the urinal. There was also a problem that it was troublesome. The present invention has been proposed in view of the above problems, and an object of the present invention is to provide a human waste processing method and a human waste processing apparatus by negative pressure suction that can easily perform human waste processing at any time by one person. It is.

[0008]

In order to achieve the above object, a method for treating human waste by negative pressure suction according to the present invention comprises receiving excreted human waste in a human waste receiving container, and collecting the human waste collected in the human waste receiving container. Is sucked and conveyed by the negative pressure generated by the suction negative pressure forming means.

Next, a human waste processing apparatus using negative pressure suction according to the present invention includes a human waste receiving container having a human waste receiving portion,
A suction negative pressure forming means for sucking and transporting the night soil of the night soil receiving section, wherein a negative pressure supply port for the negative pressure formed by the negative suction pressure forming means is opened in the night soil receiving section. Is what you do.

Further, in the human waste processing apparatus using negative pressure suction according to the present invention, the suction negative pressure forming means may be constituted by a jet pump for injecting a high pressure fluid into the negative pressure forming pipe and forming a negative pressure in the pipe. Also, a cleaning nozzle is provided in the human waste container.

For example, a bellows-shaped water tank is filled with water with a flexible synthetic resin, and the water tank is manually bent to jet cleaning water from the cleaning water jet nozzle 7. still,
Needless to say, an electric pump can be provided instead of the manual pump 8.

The suction negative pressure forming means 4 comprises: a water reservoir 9;
Although not shown, a pressure pump 12 that sucks water 10 stored in a water reservoir 9 from a strainer 11 by an electric motor driven by a commercial power supply and pressurizes the water 10, and injects high-pressure water from the pressure pump 12 to Jet pump M. J.
P. This jet pump M. J. P makes the injection nozzle 13 that injects high-pressure water from the pressurizing pump 12 face one end of the mixture jet flow forming pipe 14, and sucks outside air into the mixture jet flow formation pipe 14 near the injection nozzle 13. In addition to the opening of the suction pipe 15, a negative pressure forming pipe 16 having a larger diameter than the mixed jet flow forming pipe 14 is formed at the other end of the mixed jet flow forming pipe 14 in series. The suction port 1 is connected to the negative pressure forming pipe 16 on the jet flow forming pipe 14 side.
7 is formed as the “air-mixing jet pump MJP”.

Here, as shown in FIG. 3, an injection nozzle 13 is provided at one end of the negative pressure forming pipe 16 in place of the "mixed air jet pump", and the injection nozzle 13 and one end of the negative pressure forming pipe 16 are connected to each other.

The operation of the human waste processing apparatus 1 configured as described above will now be described. First, an electric motor driven by a commercial power supply is started to drive the pressurizing pump 12, and the water 10 stored in the water reservoir 9 is sucked from the strainer 11 and pressurized. The high-pressure water pressurized by the pressurizing pump 12 is injected from the injection nozzle 13 to the mixture jet flow forming tube 14, and when the high-pressure jet flow 22 spreads completely in the mixture jet flow forming tube 14, the mixture jet Injection nozzle 1 of flow forming pipe 14
Negative pressure due to cavitation is formed on the three side portions.

In this way, outside air is sucked from the suction pipe 15 by the negative pressure formed on the side of the jet nozzle 13 of the mixed jet stream forming pipe 14, and the sucked outside air flows through the mixed jet stream forming pipe 14. The jet stream 22 becomes a mixed jet stream containing a large amount of fine air.
6 is injected. When the mixture jet stream 23 flowing through the negative pressure forming tube 16 spreads completely in the negative pressure forming tube 16, the portion that has fully spread in the negative pressure forming tube 16 becomes the negative pressure forming tube 16.
A negative pressure is formed in the negative pressure forming pipe 16 near the mixture jet flow forming pipe 14 by acting like a continuous piston acting on the discharge port 19 side.

At this time, since a large amount of fine air bubbles are mixed in the mixed air jet stream 23 flowing through the negative pressure forming pipe 16 to the discharge port 19 side, the air bubbles are mixed with the mixed air jet stream 23.
This acts as a cushion between the inner peripheral surface of the negative pressure forming tube 16 and the inner peripheral surface of the negative pressure forming tube 16 to prevent the flow of the mixed jet stream 23 from decreasing due to frictional resistance with the inner peripheral surface of the negative pressure forming tube 16. Therefore, a large negative pressure is formed in the negative pressure forming tube 16. The large negative pressure formed in the negative pressure forming pipe 16 acts on the negative pressure supply port 5 opened from the suction port 17 through the suction pipe 18 to the bottom 3a of the human waste receiving and storing section 3.

Next, when the human waste receiving container 2 is faced to the local area and added, the human waste received in the human waste receiving portion 3 of the human waste receiving container 2 is sucked from the negative pressure supply port 5 and is sucked. 18 and the suction port 17 through the negative pressure forming pipe 16
It is sucked inside. And when the addition is over,
After the cleaning is performed by spraying the cleaning water onto a local portion by operating the manual pump 8, the moisture is wiped off with tissue paper.
Is sucked into the negative pressure forming tube 16 together with the washing water.

The human waste sucked into the negative pressure forming tube 16 and the tissue paper that has been cleaned up are agitated by the mixed jet stream 23 flowing through the negative pressure forming tube 16 and sufficiently aerated. The mixture is pulverized into a fluid by the mixed jet stream 23 having a strong flow force, and is discharged together with the mixed jet stream 23 at the discharge port 19.
From the sewage drain 21. If the local part whose moisture has been wiped off with the tissue paper is left as it is for a while, it is dried by the airflow such as the outside air flowing from the peripheral surface of the opening of the human waste container 2.
It goes without saying that a drying device for positively supplying hot air can be provided in the human waste container 2.

The suction pump M. J. The injection nozzle 13 is provided at one end of the negative pressure forming pipe 16 as shown in FIG.
A suction port 17 is formed between the suction pump 17 and one end of the pressure pump 12.
The structure in which the high-pressure water from the nozzle is directly injected from the injection nozzle 13 to the negative pressure forming pipe to form a negative pressure in the negative pressure forming pipe 16 operates in substantially the same manner as described above. In the present embodiment, the pressurizing pump 12 of the negative pressure forming means 4 is driven by an electric motor driven by a commercial power supply.
