Description

[Detailed description of the invention] (Industrial application field) This invention relates to a nursing toilet used for nursing the elderly and the like.

(Prior art) Conventionally, toilet bowls installed in toilets are equipped with a low tank for supplying flushing water into the toilet bowl and a drain pipe for discharging filth, etc. along with the flushing water. It was something that would be installed.

(Problem to be solved by the invention) Since the above-mentioned conventional toilets are installed in a fixed manner, elderly people with disabilities have to get up from the nursing room, etc. and walk to the toilet when they want to relieve themselves. In addition, even if a wheelchair is used, a caregiver must move the elderly person to the toilet every time he or she needs to relieve himself or herself.Furthermore, feces emit a foul odor, making collection work difficult and difficult to dispose of. The problem was that it was troublesome.

(Means for Solving the Problems) The present invention was devised in view of the above-mentioned conventional problems, and it can be easily installed in nursing rooms where elderly people sleep and wake up, and it is easy to dispose of defecation. The purpose is to provide nursing toilets, the gist of which is:
A toilet bowl used for nursing the elderly, etc., which includes a toilet bowl part forming a drop opening opening downward, and a sliding plate disposed below the toilet bowl part so as to be able to be pulled out. a collection bucket made of thermoplastic resin that is placed on the slide plate and capable of collecting waste that falls from the drop port; and a heat sealing means for sealing the opening of the collection bucket by heat sealing. This means that the system has been constructed with the following features.

(Function) The toilet bowl has a toilet bowl portion with a drop opening, and a sliding plate is disposed below the toilet bowl portion so that it can be pulled out, and a collection bucket is placed on this sliding plate. Therefore, the elderly can defecate into the toilet bowl of such a toilet installed in the nursing room, and the feces, etc. will fall down from the drop opening and be collected in the collection bucket. The collected waste can be easily taken out by pulling out the slide plate, and the opening of the collection bucket is heat-sealed and sealed using a heat-sealing means, which effectively eliminates bad odors emitted from the waste inside. It is possible to take the entire collection bucket outside, making it easier to dispose of waste, etc., and allowing elderly people to use the toilet easily in the nursing room, instead of having to use the toilet one by one as in the past. There is no need to go to the toilet, and the burden on the elderly and others when defecating is greatly reduced.

Moreover, the toilet bowl in this example does not require a drain pipe or a low tank like conventional ones, so it can be easily installed in nursing rooms for the elderly, etc. without the need for plumbing work, etc. It can be easily moved from room to room.

(Example) An example of the present invention will be described based on the drawings.

One or two or more dish-shaped receiving plates 8b, 8b are fixedly installed on the bottom side of the slide plate 8, and a collection bucket 9 with an open top is placed on each receiving plate 8b, 8b. It is now possible to place Therefore, when the slide plate 8 is stored in the main body 3 with the collection bucket 9 placed on the receiving plate 8b, the collection bucket 9 is aligned with the lower part of the drop port 7a, and the drop port Dirt and the like falling from 7a are dropped into this collection bucket 9.

Each collection bucket 9 is made of transparent or opaque acrylonitrile thermoplastic resin by blow molding or vacuum molding. This acrylonitrile-based thermoplastic resin has excellent gas barrier properties and chemical resistance, and when the upper opening is sealed by means such as heat sealing, it can effectively block the bad odor emitted from feces and other filth. It has the property of trapping foul-smelling gases such as ammonia. Note that the collection bucket 9 may also be made of a saran compound (polyvinylidene chloride) or the like.

The absorbent pack P can be placed in the collection bucket 9 in advance. The components of this absorption pack P will be explained in detail later.

Further, the lower part of the slide plate 8 and the base part 2
A hot water tank 10 capable of storing hot water is disposed inside the hot water tank 10, and heaters 11, 11, 11 capable of heating are disposed on the bottom of the hot water tank 10, and electricity is supplied to the heaters 11, 11, 11. As a result, the hot water in the hot water tank 10 is heated to an appropriate temperature. A cleaning nozzle pipe 10a is formed in an upright manner on the upper surface side of the hot water tank 10, and the upper end of this cleaning nozzle pipe 10a communicates with the toilet bowl part 7. It is designed to be able to spray out cleaning water.

In addition, the hot water in the hot water tank 10 is cleaned using the nozzle pipe 10a.

It is communicated with the control device so that it can be turned on and off.

Next, FIG. 2 shows a modified example of the nursing toilet bowl 1.

That is, the one shown in FIG. 2 is formed to have almost the same structure as the one shown in FIG.
The shapes of the toilet bowl portion 7, drop opening 7a, etc. are almost the same, and the collection bucket 9 etc. installed are also the same as those shown in FIG. However, the slide plate 8 shown in Fig. 1 was constructed so that it could be pulled out to the rear, but in this example, the slide plate 8 was formed into a flat plate shape, and the slide plate 8 was constructed so that it could be pulled out laterally. For example, from the left side of the figure, collected packet 9
The bucket 9 can be moved to the right side in the figure with the garbage placed thereon, and the collection bucket 9 containing the waste can be pulled out and collected from the right side in the figure.

Further, the lower part of the main body 3 has the drop port 7.
A seal bar 12, which is also provided in the toilet bowl shown in FIG. Seal bar 1
2 comes into contact with the upper part of the collection bucket 9, and the seal bar 12 is energized, so that the seal bar 1
2 is heated and pressed against the collection bucket 9 in a heated state, thereby heat-sealing the upper opening of the collection bucket 9 and sealing the waste etc. stored inside the collection bucket 9. ing. Note that the press rod 12a is operated by a motor, cylinder, etc., and is operated by a control unit 13.
It is activated by turning ON and OFF.

FIG. 3 shows and explains the sealing action of the seal bar 12. As shown in FIG. If the collection bucket 9 is divided into two rows, upper and lower, and an outwardly protruding flange 9a is integrally formed at the top opening of the collection bucket 9, the pressure rods 12a, 12a can be operated respectively. Accordingly, seal bar 1
2 and 12 are moved to a position close to each other, so that the collection bucket 9 can be sandwiched between them, and the lower side of the seal bar 12 arranged in the vertical direction is placed in front of the upper side without moving close to each other. First, the lower seal bar 12 is used to clamp the lower surface of the flange 9a of the collection bucket 9, and when the flange 9a is deformed upward as shown in FIG. 3B, the upper seal bar 12 is brought closer. Upper seal bar 1 as shown in Figure 3
2, first seal the tip of the flange 9a, then further clamp the lower seal bar 12,
The upper opening of the collection bucket 9 can be sealed with double heat sealing. At this time, for example, dust paper K or the like is thrown into the collection bucket 9, and the dust paper K may obstruct the sealing performance of the opening of the collection bucket 9. Instead, if you use dust paper K made of ionomer resin or polyolefin resin,
Even when the dust paper K is pinched during heat sealing by the seal bar 12, since the dust paper K is made of resin, it is integrally sealed with the collection bucket 9 by the heat of the seal bar 12, and the collection bucket 9, the sealing performance is good.

Incidentally, FIG. 4 shows a modification of the collection bucket 9.

That is, the collection bucket 9 shown in plan view in FIG.
is formed to have a thickness of, for example, about 250 μm, and has a handle 9b integrally formed in the upper opening to project outward. Such a handle 9
When using the collection bucket 9 formed with b.
At the lower part of the main body 3 of the nursing toilet bowl 1, a pair of V-shaped seal guides 14 are disposed integrally with the seal bar 12 or in place of the seal bar 12, and are disposed opposite to each other. If the structure is such that heat rollers 15, 15 that can be heated are arranged near the seal guide 14, the nurse can remove the collection bucket 9 after the waste has been dropped into the collection bucket 9 after defecating. By holding the handle 9b with your hand and pulling the handle 9b along the seal guide 14 as shown in FIG. 4B, the upper opening of the collection bucket 9 will be opened along the seal guide 14 as shown in FIG. By passing the handle 9b between the pair of heat rollers 15 and further pulling it, the opening of the collection bucket 9 is well heat-sealed by the heat rollers 15, 15.
As shown in FIG. 4D, the upper opening of the collection bucket 9 is heat-sealed integrally with the handle 9b, so that the waste inside is sealed.

Next, the absorbent packs P that are placed in each collection bucket 9 in advance will be explained.

This absorbent pack P is formed into a bag shape from, for example, water-soluble polyvinyl alcohol resin.

A granular or solid water-absorbing resin is enclosed within this bag-like film of polyvinyl alcohol resin.

This water-absorbing resin is a copolymer of a monomer such as a hydrolyzate of a starch-acrylolytrile graft polymer, a hydrolyzate of a cellulose-acrylolytrile graft polymer, and a crosslinking agent, such as a crosslinked polyacrylamide. and its hydrolyzate, crosslinked sulfonated polyethylene, crosslinked Popal, crosslinked vinyl ester-unsaturated carboxylic acid copolymer saponified product, crosslinked polyacrylate and acrylic acid-acrylic acid copolymer, crosslinked isobutylene-maleic anhydride copolymer, crosslinked polyethylene oxide, etc., and also polymers having self-crosslinking properties, such as self-crosslinking polyacrylic acid, the resin described in Japanese Patent Publication No. 54-30710, High molecular weight polymers containing at least a hydroxyl group and a carboxyl group in the molecule, for example,
The resin described in No. 37994 may also be used. In addition, it is a water-absorbing resin obtained by polymerizing starch or cellulose, a water-soluble monomer and/or a monomer that becomes water-soluble by hydrolysis, and a crosslinking agent as essential components, and hydrolyzing if necessary. Also good.

Even if the above water-absorbing resin is one type, or two types
More than one type may be used, and the water absorption performance is preferably about 20 to 2000 g/g. Furthermore, these water-absorbing resins may be in the form of powder or fibers, and in addition to being encapsulated within the aforementioned polyvinyl alcohol resin film, they may also be encapsulated in paper, cloth, etc. .

With the absorbent pack P configured as described above placed on the bottom of the collection bucket 9, waste can be dropped into the collection bucket 9 and collected, and at this time, the washing water from the hot water tank 10 is removed together with the waste. Because it falls into the collection bucket 9 at the same time, the collection bucket 9
The water-absorbent resin sealed in the inner absorbent pack P absorbs the water from the washing water and dirt, expands as it absorbs water, and tears the outer film.The film is also made of polyvinyl alcohol resin. Sometimes, because they are water-soluble, they naturally break due to moisture, so the water-absorbing resin inside can absorb the moisture in the waste and expand well. In this state, the seal bar 12 is pressed near the upper opening of the collection bucket 9, and the seal bar 12 heat-seals the opening of the collection bucket 9, thereby sealing the excrement H inside. Moreover, in this state, the excrement H in the collection bucket 9 has become a dehydrated solid substance, and is returned to the collection bucket 9 as it is.
Even if it is taken outside, the bad odor is well contained due to the gas barrier properties of the acrylonitrile thermoplastic resin that constitutes the collection bucket 9. Therefore, the collection bucket 9 can be taken out without causing discomfort.

In addition to the water-absorbent resin sealed in the absorbent pack P mentioned above, if a powder such as aluminum dihydrogen tripolyphosphate or ascorbic acid is simultaneously sealed in the absorbent pack P, aluminum dihydrogen tripolyphosphate Due to its adsorption ability for ammonia and trimethylamine, malodorous components can be better absorbed and waste can be collected into the collection bucket 9 better.
Furthermore, the absorption pack P contains silica gel,
Activated carbon, deolite, activated alumina, aromatic agents, etc. can be enclosed, and the deodorizing and water absorbing effects of these components allow for better processing.

(Effects of the invention) The present invention is a toilet used for nursing the elderly, etc., which includes a toilet bowl portion forming a drop opening opening downward, and a toilet bowl portion formed below the toilet bowl portion. A slide plate arranged to be pulled out, a collection bucket made of thermoplastic resin placed on the slide plate and capable of collecting waste that falls from the drop port, and an opening of the collection bucket heat-sealed. Since it is equipped with a heating sealing means for sealing the toilet, it does not require piping equipment or a low tank like conventional toilets, so it can be easily installed in a nursing room for the elderly, etc., and is suitable for nursing care. Elderly people can easily defecate indoors, etc., and the excreted waste falls from the drop opening and is well collected in the collection bucket, and is collected by pulling out the slide plate of the collection bucket and removing the waste. It can be taken outside together with the collection bucket, and the collection bucket is heated and sealed.
The opening is heat-sealed and sealed, effectively blocking out the odors emitted from the filth inside.
In addition to making it easier to dispose of filth, the elderly do not need to go to the toilet when defecating, etc., which greatly reduces the burden on the elderly when defecating, and has an extremely effective effect in nursing the elderly.
