The pump 32 is connected so as to suck air from the recovery tanks 30 and 31, starts suction at the same time when the opening / closing valve 21 of the water supply mechanism 2 opens, and stops after a predetermined time has elapsed since the opening / closing valve 21 closed. Therefore, the operation is controlled in conjunction with the operation of the on-off valve 21.

The recovery tank 30, as shown in FIG.
It is composed of an outer container 302, a lid 303, an inner container 304, and a waste pack 305. The recovery tanks 30 and 31
Since the configuration is the same, one recovery tank 30 will be described in the following description. The outer container 302 has a pipe-shaped suction port 30 that penetrates a wall surface of the outer container 302 and has a tip protruding inside.
0, and the position facing the suction port 300 is an opening.

The lid 303 is attached so as to close the opening of the outer container 302, and has a discharge port 300 to which the pump 32 is connected. Inside the lid 303, a deodorizing filter layer 3030 made of a material having a deodorizing, deodorizing or disinfecting action is provided, and the air sucked from the outer container 302 to the outside is always the deodorizing filter layer 3
After passing through 030, it is discharged to the outside from the pump 32 as clean air. For this deodorant filter layer 3030, for example, activated carbon or the like is used.

The inner container 304 is a bag made of a breathable film that is almost impermeable to water, and the outer container 30 is
It can be connected to the two suction ports 300. Examples of the breathable film include a film obtained by laminating a polyfilm and a non-woven fabric on a microporous film. One side of this inner container 304 is a fastener 30.
By 40, it can be opened and closed in an airtight seal and is sealed in a state in which an excrement pack 305 described later is accommodated.
It is designed not to be sucked out. Further, a check valve (not shown) is provided at the opening to which the suction port 300 of the inner container 304 is connected so as to prevent the stored filth from flowing backward.

The excrement pack 305 is made of a breathable material such as woven cloth or non-woven cloth, and is used as the outer container 3.
No. 02 is held in the inner container 304 so that the inflow from the inlet 300 can be received without leaking. In this excrement collection device, the excrement is washed away by the hot water jetted from the washing nozzles 100, 110, and is drawn into the collection tanks 30, 31 together with the hot water used for washing by suction of the pump 32.

The excrement and warm water for washing drawn into the recovery tanks 30 and 31 are contained in the excrement pack 305. The air sucked together with the excrement and the warm water for cleaning passes through the excrement pack 305 and the inner container 304, is sucked out by the outer container 302, passes through the deodorizing filter layer 3030 of the lid 303, and is discharged from the pump 32 to the outside. Exhausted to.
When discarding the excrement collected by this excrement collection device, the lid 303 is removed and the excrement pack 305 together with the inner container 304 is taken out from the outer container 302, and the inner container 304 is removed.
The fastener 3040 of 1 is opened, the excrement pack 305 is discarded at the place where the waste is discarded, and the inner container 304 may be discarded as general waste.

Then, a new inner container 304 containing a waste pack 305 is set in the outer container 302 from which the inner container 304 has been taken out. In the above example,
If the excrement pack is made of water-soluble woven or non-woven fabric,
This can be flushed to the flush toilet. Further, by disposing a layer of a water absorbing agent such as that used in a disposable diaper on the excrement pack and solidifying the collected waste in a jelly form, the disposal process becomes extremely simple.

Also, the inner container and the waste pack may be disposed of as a unit without being separated. Also, the shape of the cup may be any as long as it is in close contact with the skin and does not interfere with lying down, and the shape and arrangement of the cup for men and women are naturally changed. It is a thing. In addition, urine is collected by a conventional collection device,
Only the stool may be collected by the excrement collection device according to the present invention. Also, for cleaning and suction, only the line of the urine cup may be operated when only urinating, and both of them may be operated when urinating, and the inside of the cup should be wet before excretion by the operation of the person requiring care. You may make it difficult for dirt to adhere.

The shape and number of washing nozzles provided in the cup are not limited to those in the embodiment, and for example, a washing nozzle for washing the cup and a washing nozzle for washing the skin may be provided separately. Alternatively, all the excrement may be received in one elongated cup. Also, the collection tank should be flexible and compact so that it can be attached to the thighs of the underwear one by one, or be placed under or beside the bedding where the care recipient is sleeping. However, the recovery tank may collect all excrement in one tank.

Further, the inside of the cup may be dried by continuing to operate the pump for a while after the cleaning is completed, or by blowing warm air from the warm air supply device into the cup. Further, the water supply mechanism may be provided with an independent water supply tank without using the hot water mat, and the hot water may be supplied from the tank as needed. In addition, the inner container of the recovery tank does not have to be formed of a breathable film over almost the entire surface, and may be one in which a region formed of a breathable material is provided.

When the collection process is completed, a lamp is automatically turned on or a chime is sounded to send a signature to the caregiver, the collection tank is replaced promptly, and moistened with warm water for cleaning. You may be asked to clean the existing skin and the inside of the cup. Even in this case, since no or almost no dirt remains in the area to be wiped, the burden on the care giver and the care recipient is significantly reduced as compared with the conventional diaper change.
