JPH0380860A - Nursing bed with stool and deodorizing method in this bed - Google Patents

Abstract

PURPOSE:To efficiently eliminate a foul odor by providing a foul odor suction hole, and a deodorizing tank which has a deodorizing water solution, and also, in which a foul odor sucked from the hole is emitted under the liquid level, on a stool. CONSTITUTION:When a user evacuates the bowels, rubber tubes 1, 2 and 3 expand since air is injected and a lavatory seat is formed, and rubber tubes 5, 6 contract. In this case, a suction pump 12 is operated automatically, a foul odor is sucked from a hole 7 positioned near a source of the odor, and thereafter, sent into a deodorizing tank 15, and the foul odor is melted into a water solution and eliminated. After evacuating the bowels, contamination of the lavatory seat 4 is washed away by washing water, and thereafter, an opening/ closing valve in a valve 20 is closed and warm water is supplied from a supply port 10. Subsequently, air is supplied from a bubble washing hole formed in the lower part of the lavatory seat 4, and the buttocks part 21 is washed by these bubbles and warm water. Thereafter, washing warm water is discharged, hot air is blown out, and the buttocks part 21A and the rubber tubes 1, 2, 3, 5 and 6 are dried.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of use in M industry This invention relates to a nursing care bed with a toilet bowl used for physically disabled patients, bedridden elderly people, etc., and a method for deodorizing the same.

(Existing technology) The conventional technology for nursing care beds with toilet bowls is
As described in Japanese Patent No. 194336, some toilets are equipped with a flush toilet.

In addition, as described in Japanese Utility Model Publication No. 55-5936, odor can be sucked from the end of a vinyl cloth that is hung around the lower body during defecation, and the odor can be passed through a deodorizing tank to remove the odor. There is a suction deodorizing device.

(c) Problems to be solved by the invention However, although the above-mentioned bed with a flush toilet is hygienic because excrement is washed away with water, it also eliminates the odor of excrement and the odor emitted from the body during defecation. It was impossible.

In addition, although the above-mentioned odor suction deodorization device removes the odor of excrement and excrement odor, it has the disadvantage that it is difficult to remove the odor because the odor is sucked from the edge of the vinyl cloth, that is, from a place far from the source of the odor. was there. For this reason, the odor would not be removed sufficiently unless the lower body was covered with a vinyl cloth for a while after defecation, which was very troublesome.

The present invention provides a nursing care bed with a toilet bowl that can efficiently remove odors, and a method for deodorizing this bed.

(2) Means for Solving the Problems In order to solve the problems of the prior art described above, the present invention provides a nursing care bed with a toilet bowl for sucking and removing odors during defecation and odors from excrement. A hole is placed in the toilet bowl to avoid a place where excrement can flow down or be blocked by the toilet seat.
The structure is such that odor is sucked in and removed through these holes.

<*) Function: In the nursing care bed with a toilet bowl according to the present invention, holes are provided to suck in odors from the forest, excrement odor, and excrement in the toilet bowl, which is very close to the source of these odors. The odor is sucked in from a position close to the source of the odor, making the suction of the odor more efficient and removing the odor from the vicinity of the toilet bowl and the nursing care bed with the toilet bowl.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a plan view of essential parts of the nursing care bed with toilet bowl according to the present invention, and FIG. 3 is a sectional view of the ■-curve shown in FIG. 2 of the nursing bed with toilet bowl,

In this figure, (12) is a suction pump connected to the odor pipe (8), and (13) is a suction pump connected to the odor pipe (8). One end of the suction pump is connected, and the other end is a glass filter (1

The valve (22) is equipped with an on-off valve (not shown) that can be opened and closed, and the valve (22) is used to collect excrement from the user (21), such as a physically disabled patient or a bedridden elderly person, the toilet bowl (4), and the buttocks (21A). A toilet tank (23) is used to store the washing water after it has been used for washing;

In the nursing bed with toilet bowl of the present invention configured as described above, when the user (21) is sleeping, air is supplied to the rubber tubes (1), (2), (3), (5), and (6). It has the same height as the pine tress (11), that is, it has a substantially flat shape (see FIGS. 4 and 5).

In addition, people who are unable to move freely have their weight concentrated in one part of their body all the time, and if this part is compressed, blood flow is obstructed and it is easy to become unclean. It is said that picking up is likely to occur. According to the nursing bed with a toilet bowl of the present invention, the opening and closing of the air supply/exhaust device (18) and the tubes (19) leading to each rubber tube are controlled by setting a timer. tube(
The user (
21) gives the buttocks (21A) an effect similar to a pine surge, and prevents one area from being continuously compressed,
It is controlled to prevent the occurrence of bedbugs. In addition, in order to prevent the buttocks (21A) of the user (21) from becoming unclean, the buttocks (21A) are washed with warm water and dried with warm air, as described later, to prevent bed marks from forming. It is effective in preventing

That is, when the user defecates, the rubber tubes (1), (2), and (3) are expanded by injecting air to form a toilet seat, and the rubber tube (5)
(6) is contracted (see Figures 1 and 2).

At this time, and when the user defecates, the suction pump (12)
is activated automatically, and the odor is sucked in from the hole (7), that is, from a position close to the source of the odor, which improves the efficiency of suctioning the odor.Then, it is sent into the deodorizing tank (15), and the odor is removed. The odor is removed because it dissolves in the aqueous solution.Odors and excrement emitted from humans are generally water-soluble, and
Because a deodorizing agent is added to the aqueous solution in the deodorizing tank (15), and because the filter (14) is configured to increase the contact area between the odor and the aqueous solution,
Most of the odors are removed in this deodorizing tank (15).

After defecating, after the dirt in the toilet bowl (4) is washed away with flushing water from the supply port (10), the on-off valve inside the valve (20> is closed and warm water is poured from the supply port (10) until the buttocks (21A) are submerged. Then, air is supplied from a foam cleaning hole (not shown) formed at the bottom of the toilet bowl (4), and the buttocks (21A) are cleaned with the foam and warm water.After this, the valve ( The opening/closing valve in the toilet bowl (20) opens, the hot water for washing is discharged, and the hot air is blown out from the hot air hole for drying (not shown) formed in the toilet bowl (4).
) and rubber tubes (1) (2) (3) (5) (6)
is dried. After this, air is injected into the rubber tubes (5) and (6) so that the height is almost the same as that of the pinerest (11), and the backrest (IIA) is folded down and the legs (IIC) are The user (21) can also sleep on this bed because the bed is raised and a flat bed is formed.

In addition, in the present invention, the suction pump (12) is automatically activated during defecation, but if there is an odor in the vicinity, the suction pump (12) can also be activated by operating the switch (26) or the like.
) may be configured so that the nursing care bed with a toilet bowl can be operated.

(G) As described in detail of the invention, according to the present invention, the odor is sucked from the toilet near the source of the odor, so the odor is efficiently removed, so that the toilet is comfortable, with no odor remaining around. A nursing care bed and a method for deodorizing the bed can be provided.
