Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a care mat device and a care hot bath method provided on a care bed for a care recipient such as a so-called bedridden elderly person.

[0002]

2. Description of the Related Art Conventionally, regarding bathing for a physically handicapped sick person, an elderly person (hereinafter referred to as a cared person) who need nursing care, when moving from a nursing bed to a bathtub,
The main focus was on how to reduce the burden on care recipients and caregivers. That is, in a care bed, for example, by having a structure in which the upper half of the bed surface can be lifted, the upper half of the care recipient can be raised while the burden on the care recipient is reduced. I was able to get off easily from.

As means for moving from the care bed to the bathtub, in order to reduce the burden on the caregiver, for example, a part of the cared person's body is grasped / suspended and carried or movement is assisted. A crane device and a bed with a crane device, which is a combination of this crane device and a nursing bed, have also been proposed. In addition, there are bathtubs in which the care receiver takes a bath, for example, those with handrails or the shape of the bathtub devised so that the care receiver can easily enter the bathtub or change his / her posture easily.

However, in the above, since the bed and the bathtub are basically separate and independent and are provided at different places, when the care recipient takes a bath, the caregiver is in a sleeping position. The work of raising the cared person on the bed → removing it from the bed → moving it from the bed to the bathtub → putting it in the bathtub required a great burden on the caregiver. In particular, in the procedure of putting the care recipient in the bathtub,
Two caregivers are required to work on the floor, which is extremely difficult. Further, the crane device for moving from the bed to the bathtub has a large and complicated device structure and is very expensive.

Therefore, in response to the above, for the purpose of making it possible to take a bath in a bed with a simple and inexpensive structure and facilitating the bathing of a care receiver to reduce the caregiver's labor and burden, for example, Japanese Patent Application Laid-Open No. As described in JP-A-9-248229, a fixed bed portion (orientation) provided so as to surround the outer peripheral region of the bed, and a movable floor portion (floor board) provided on the inner periphery side of these orienting beds are provided. Block), a water reservoir provided between two floor plate blocks near the center, a drain hole provided in the water reservoir, a handrail provided on each of the tilts, and a tilt support for supporting the tilt. The one that is composed of is proposed.

When the care recipient takes a bath (warm bath), the floor plate upper and lower jacks are operated to form a recess in the floor plate block, and then the folded water-impermeable sheet (tub forming cloth) is opened to form the floor plate block. Cover the upper surface of the recess and the surrounding tilt and form a bathtub inside. After that, hot water for hot bath is supplied by the hot water supply means so that the care recipient can take a hot bath.

[0007]

However, the above-mentioned conventional techniques have the following problems.

[0008] That is, although not explicitly stated in the above-mentioned prior art, after the warm bath is finished and the drainage is performed, it is sufficient to drain the care-receiver himself and the non-permeable sheet on which the care-receiver is placed. Instead, it is in a wet state, so normally a separate towel or the like is prepared and the care recipient wipes off the water.

However, even if such a wiping operation is carried out to some extent, it is difficult to completely wipe off the water and dehumidify it. Furthermore, a caregiver who has been warmed by a warm bath is likely to sweat, and especially the lower part of the caregiver's body located on the side of the water impermeable sheet tends to be humid. If the wet state after such a warm bath is left as it is, it is not preferable in terms of hygiene of the water-impermeable sheet, and it is difficult to prevent generation of, for example, a bad odor or mold. Further, it is uncomfortable for the caregiver's body, which is not preferable from the viewpoints of preventing bedsores, preventing bacteria and sanitizing, and hygiene.

An object of the present invention is to provide a care mat device and a care hot bath method capable of sufficiently dehumidifying a care receiver and the surroundings thereof after a warm bath.

[0011]

It has a bag-shaped portion provided with an air ejection port for ejecting air to the outside.

In the present invention, for example, after the warm bath is finished and drainage is performed, a caregiver separately wipes off the moisture of the care receiver and the surroundings, and then a cloth sheet is laid on the care receiver. The air from the air supply / exhaust means is fed into the inside of the bag-shaped portion through the air introduction port while lying down, and the air is ejected from the air ejection port provided in the bag-shaped portion. The jetted air dries the moisture of the body of the care-receiver in a high-humidity state and the water-impermeable sheet on which the care-receiver is placed, so that dehumidification can be sufficiently performed as a whole.

(2) In order to achieve the above-mentioned object, the nursing mat device of the present invention has a water-impermeable sheet that covers the recess provided in the nursing bed and serves as a bathtub, and a function of sending in air and a function of exhausting air. And an air feed / exhaust means provided with, the water-impermeable sheet, at least one row along the longitudinal direction of the air inlet and the care bed for introducing the air from the air feed / exhaust means into the inside. And a bag-shaped portion having an air ejection port for ejecting the air introduced from the air introduction port to the outside.

(3) In order to achieve the above object, the nursing mat device of the present invention further includes a water-impermeable sheet that covers the recess provided in the nursing bed and serves as a bathtub, a function of sending in air, and a function of exhausting air. And a non-water-permeable sheet, wherein the water-impermeable sheet has an air introduction port for introducing air from the air supply / exhaust unit to the inside and the air introduced from the air introduction port to the outside. And a plurality of protrusions provided at least at positions corresponding to the lying position of the lying person of the care bed.

As a result, the ventilation under the body of the cared person can be improved even when the cared person is lying down. Further, by providing the protrusion as a cushion, there is an effect that the cared person's feeling can be improved and bed sores can be suppressed.

(4) In the above item (3), it is more preferable that the air ejection port is provided in the vicinity of the plurality of protrusions.
In addition, it is provided at a position where the jetted air is ventilated along the surface of the water impermeable sheet even when the lying person is lying down.

Thus, the air sent from the air sending / exhausting means and jetted from the air jet outlet can be surely ventilated even when lying down, so that dehumidification can be performed more reliably.

(5) In any one of the above (1) to (4), and preferably, the drainage port provided in the water impermeable sheet is detachably provided, and a predetermined water surface position of the stored water. It has a water conduit that introduces water through the opening and drains it.

Thus, the hot water for the warm bath can be reliably stored up to the predetermined water surface position.

(6) In any one of the above (1) to (4), and preferably, an inflatable and inflatable air bag is provided on the outer peripheral portion of the recess of the care bed.

By inflating the air bag arranged on the outer peripheral portion of the recess during the warm bath, the volume of the warm water stored in the impermeable sheet can be reduced by the volume occupied by the air bag in the inflated state. it can. In addition, there is an effect that the weight burden on the entire bed can be reduced and the durability can be improved.

(7) In order to achieve the above-mentioned object, the method for warming bath for care of the present invention is to cover the concave portion provided in the care bed with a water impermeable sheet to supply hot water, and the care recipient is placed on the water impermeable sheet. After performing the warm bath, the water is drained, air is sent into the impermeable sheet with the caregiver lying on the impermeable sheet, and air is ejected from the air ejection port provided on the surface. The water-impermeable sheet and the care receiver are dehumidified by being ejected.

[0023]

On the other hand, as shown in FIG. 3, air is taken in and out from both left and right ends of the mat 6 as seen from the care-receiver M (ends of the folded portion of the water-impermeable sheet 7). As a result, the air bag 15 that can be expanded and contracted is arranged.

FIG. 9A is a partially enlarged view of FIG. 3 showing the detailed structure of the air bag 15. In FIG. 9A, the air bag 15 includes a bag body 15a and a bag body 15a.
And a pipe connection portion 15b provided with, for example, a check valve or a simple stopper. Although it is normally in a contracted state as shown in the drawing, by connecting the above-mentioned air supply / exhaust hose 13 to the pipe connection portion 15b and introducing air from the air supply / exhaust device 12, it is possible to cross as shown in FIG. 9 (b). It swells in a substantially triangular shape (see arrow). When it is desired to shrink the inflated object again, the air is sent and exhausted by the air supply / exhaust device 12 (see the arrow).
It is supposed to return to a contracted state like. The length of the air bag 15 in the longitudinal direction is about half that of the mat 6 (see FIG. 11 described later).

Next, the procedure of the bathing (hot bathing) method for the care-receiver M using the above-mentioned care bed and care mat device, which is the main part of this embodiment, will be described step by step.

First, as a preparation procedure, as shown in FIG. 10, about half of the mat receiving frame 5 and the mat 6 (upper body side of the cared person M) is rotated and lifted by a known driving means or manually. By this, the upper half of the cared person M is raised to a so-called reclining state. In this state, the end of the water-impermeable sheet 7 is still in the folded state, and the air bag 15 is also in the folded state.

Next, as shown in FIG. 11, the care receiver M is placed on the portion outside the recess 2-1 of the water impermeable sheet 7 folded on the left and right sides of the care receiver M. The upper part of the bed main body 3 is broadly covered by unfolding as it is and hanging it outward from the outer peripheral handrail portion 3a.
Further, one end side of the air supply / exhaust hose 13 is connected to the air supply / exhaust device 12, and the other end side of the air supply / exhaust hose 13 is already arranged in a state of being folded to the left and right sides of the care receiver M. It is connected to the pipe connection portion 15b of the bag 15. The air supply / exhaust device 12 is provided with a known air pump and the like, and functions as an air supply / exhaust means for sending air (which also functions as an exhaust means for exhausting air, as described later). That is, by blowing air into the air bag 15 to inflate it, the air bag 15 has a substantially triangular tubular shape along the body direction of the care-receiver M on the left and right sides of the care-receiver M as shown in FIG. Inflate (see also FIG. 13 described later). In addition, in FIG. 11, the care receiver M is not shown in order to prevent the drawing from being complicated.

Thereafter, after removing the mat 6 laid under the body of the care-receiver M, the body of the care-receiver M is lightly lightened by using shower water from the shower plug 16a provided in the publicly known hot water supply facility 16. Shower ring (Fig. 12 described later)
(a) and FIG.12 (b)). The water after washing is passed through the water-impermeable sheet 7, the mat 6, the mat receiving frame 5, and the drain pipe 17 provided through the bed base 3b in advance to a known drainage facility or sewer pipe. Be drained. The shower procedure may be omitted and the next warm bath procedure may be immediately performed.

Next, the through hole 6a for drainage provided in the mat 6 is formed.
A water level holder 18 that keeps the water surface constant and plays a role of a faucet is installed upright above the upper edge portion of the drain pipe 17 provided so as to be inserted from below so as to be inserted into the through hole 6a for drainage from above. Install. Then, hot water for bathing is supplied from the hot-water tap 16b provided in the hot-water supply facility 16 to store hot water in the recessed non-permeable sheet 7, and the care-receiver M
Take a bath (hot bath). FIG. 12 (a) shows this state. Note that FIG. 12B is a transverse sectional view taken along the line XII-XII in FIG. Further, FIG. 13 is an enlarged view of portion B in FIG. As shown in FIG. 13, first, a mat-shaped ring 21 having a flange (cylindrical shape) with flanges 21a and 21b at both upper and lower ends is inserted and fixed into the mat drain hole 6a. A threaded portion 21c is provided on the inner peripheral side of the mat through ring 21, and the drain pipe 17 is provided.
The threaded portion 17a provided on the outer peripheral side of the upper edge portion is screwed into the lower area of the mat through ring threaded portion 21a, whereby the drain pipe 17 and the mat 6 are fixed.

On the other hand, the threaded portion 21 of the mat through ring 21
An outer peripheral side threaded portion 22b of a cylindrical impermeable sheet fixing ring 22 with a single collar having a flange portion 22a at the upper end is screwed and fixed to the upper region of c. At this time, the water impermeable sheet 7 is sandwiched and fixed between the lower portion of the collar portion 22a of the water impermeable sheet fixing ring 22 and the upper collar portion 21a of the mat penetrating ring 21 with the water blocking packing 24 interposed. .

A threaded portion 22c is further provided on the inner peripheral side of the water impermeable sheet fixing ring 22, and the threaded portion 1 provided on the outer peripheral side of the lower edge of the water level holder 18.

With the above structure, the water level holding device 1
Only the amount of water that exceeds the upper end position of 8 is introduced into the water level holding device 18 as shown by the arrow in FIG. As a result, the water level is always held at the upper end position of the water level holding device 18, and the water level is prevented from excessively rising and overflowing around the bed beyond the outer peripheral handrail portion 3a.

At this time, the air bag 15 is placed before the warm bath.
By inflating, the volume of hot water stored in the water impermeable sheet 7 can be reduced and saved by the volume occupied by the air bag 15 in the inflated state. In addition, the above also has the effect of reducing the weight burden on the bed cradle 4 and improving the durability of the bed body 3.

After the caregiver M has finished the warm bath for a predetermined time, the water level holder 18 is removed and the water on the water impermeable sheet 7 is drained. Then, the caregiver appropriately wipes off the water remaining on the water impermeable sheet 7 and the water adhering to the body surface of the care-receiver M with a towel or the like. At this time, wiping is performed while appropriately shifting the body of the care-receiver M to the side or changing the posture.

After that, on the water-impermeable sheet 7 (in other words, between the water-impermeable sheet 7 and the care-receiver M), the care-receiver M's body is laterally displaced or the posture is changed. After arranging the sheet 8 again while interposing,
As shown in, the other end of the air supply / exhaust hose 13 having one end connected to the air supply / exhaust device 12 is connected to the air supply connection valve 10 of the water impermeable sheet 7. Then, in a state where the care-receiver M is laid on the water-impermeable sheet 7 (although the bed body 3 itself is in the reclining state as described above), the air-supplying / exhausting device 12 is used for guiding the water-impermeable sheet 7. Air is fed into the bag-shaped portion 9 and air is ejected from the air ejection port 11 provided on the surface thereof (see arrow).

The jetted air dries the body of the care-receiver M and the water-impermeable sheet 7 on which the care-receiver M is placed through the sheet 8 to dry the water, thereby sufficiently performing the dehumidification as a whole. be able to. Therefore, the caregiver's discomfort can be eliminated, and further hygiene or antibacterial
It can be improved from the viewpoint of sterilization. Further, at this time, by arranging the air ejection port 11 and the protruding portion 14 as shown in FIG. 7, the air ejected from the air ejection port 11 is formed along the surface of the water impermeable sheet 7 even when the care receiver M is lying down. Since it can be ventilated, the dehumidification can be performed more reliably. In addition, as the effect of the protrusions 14 alone, there is an effect that the cushioning function can improve the sensation of the cared person and can suppress the bed sore. Note that this dehumidifying work is performed in a reclining state in which about half of the mat receiving frame 5 and the mat 6 (the upper body side of the care receiver M) are lifted so that the care receiver M raises the upper body as described above. The mat receiving frame 5 and the mat 6 are not limited
Alternatively, the care-receiver M may perform the operation in a state where the care-receiver M is lying horizontally. Also in this case, the same effect is obtained.

After the above-described series of steps is completed, the air supply / exhaust hose 13 is connected to the drain pipe drying air supply pipe 19 which is provided in advance through the through hole formed in the outer peripheral handrail portion 3a branched from the drain pipe 17. Connect the other end of the
By supplying more air, it is possible to dehumidify and dry the drain pipe 17 as well, and prevent generation of mold and the like. Reference numeral 20 is an on-off valve provided in the drain pipe drying air supply pipe 19.

In the embodiment of the present invention described above, as shown in FIGS. 7 and 8, the substantially hemispherical projection 14 is provided in the region K1 of the water impermeable sheet 7, but this is not the only option. However, it is also possible to provide a protrusion 14 'having another shape, for example, a substantially quadrangular (square tube) shape as shown in FIG. Also in this case, the same effect is obtained.

In the embodiment of the present invention, as shown in FIG. 4, the water-impermeable sheet 7 is provided with the air ejection port 11 in the longitudinal direction of the care bed 1 (left-right direction in FIG. 4). Although the baffle bag-shaped portions 9 are arranged in a row along the air-guiding portion 9, the present invention is not limited to this. For example, as shown in FIG. A bladder-like portion 9'for arranging 11 in a plurality of rows (two rows in this example) may be provided along the longitudinal direction of the care bed 1 (horizontal direction in FIG. 16). Also in this case, the same effect is obtained.

Furthermore, in the above-described embodiment of the present invention, the air from the air supply / exhaust device 12 is used only for dehumidification, but the present invention is not limited to this. That is, the air supply / exhaust device 12 is provided with a function of adjusting the temperature or humidity of the air like a normal air conditioner, or a separate temperature or humidity adjusting means can be connected to the air supply / exhaust hose 13 to supply hot air / humidity.
The cold layer is supplied and the air layer is positively impermeable sheet 7
If it is generated in the vicinity, it is possible not only to dehumidify but also to provide a more comfortable environment for the care recipient.
