Description

This device can be used in nursing, nursing, childcare, pet fields, etc.
The present invention relates to a unidirectional moisture holding body that can be used repeatedly and can be dehydrated without dehydration at body pressure while holding water.

The followings are known as inventions and devices aimed at the sanitary environment of the user by the excrement of the nursing care site.

JP 2001-204609 A Japanese Patent Application Laid-Open No. 07-039564 However, the sheets described in Patent Documents 1 to 3 that are only intended for water absorption have a problem that the absorbed water oozes out again due to body pressure, and the clothes and bedding may be damaged. there were.

The water-absorbing sheet described in Patent Document 1 cannot be solved by the body pressure once the water has been absorbed. Therefore, there is a risk that excrement may leak and soil the clothing bedding.
In addition, the water-absorbing sheet of Patent Document 3 has a risk of accelerating the global warming problem for the purpose of disposal and incineration each time it is used.

The present invention has been made in view of such a problem, and a moisture retaining body that minimizes contamination of a user's clothes and bedding while suppressing the return of body fluid and excrement once absorbed by body pressure. The purpose is to provide.

The present invention that meets the above-described problems is a sheet-like moisture holding body that is used to absorb body fluid or excrement and has a water absorption surface and a non-water absorption surface, from the water absorption surface side toward the non-water absorption surface side. And
A first layer having water permeability, a second layer having air permeability therein and having water permeability, a third layer capable of absorbing and retaining moisture transmitted through the first layer and the second layer, and moisture content. A fourth layer made of a non-permeable material is sequentially laminated, and one or more of the first layer to the fourth layer is formed of a fiber material and moisture held in the third layer is applied to body pressure. The above-mentioned problem is solved by providing a unidirectional moisture holding body characterized in that it does not ooze out from the water-absorbing surface in a wet state.

According to the present invention, due to the unidirectional water-absorbing structure, once the water is absorbed, the return due to body pressure is suppressed, so that the clothes bedding can be prevented from being damaged. Not the sheets that cover the entire bed and mattress,
Since it is embedded so as to partially cover the buttock, the user can be placed in a recumbent state during replacement, and can be removed and replaced.
It can be easily exchanged without transferring the user from the bed to a wheelchair, etc., greatly reducing the burden on the caregiver and nurse. Also, as a vehicle seat surface application, the body side surface of the vehicle seat body is provided by a squeezing locking member provided with a body side portion on the unidirectional moisture retaining body without transferring the excrement of the user's excrement etc. to the vehicle seat body. Can prevent the drop-off.

It is a modification which concerns on 1st Embodiment of this invention. It is a figure concerning a 1st embodiment of the present invention. It is a figure which concerns on 2nd Embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same or equivalent part in a figure.

As shown in FIG. 1, a is a laminated structure diagram of a unidirectional moisture holding body. a-1 is a unidirectional material which is the first layer having water permeability. a-2 is a second layer containing air and having water permeability.
a-3 is a third layer made of a water-absorbing material capable of absorbing and retaining moisture that has passed through the first layer a-1 and the second layer a-2. a-4 is a fourth layer made of a material that does not transmit moisture.
In the unidirectional moisture retaining body replacement method, it is preferable that the user is in a lying position, one side of the unidirectional water-absorbing sheet is rolled up, the position is changed and reversed. Further, the first layer material may be a material that reacts with moisture to change its color so as to be a sign for replacement.

As shown in FIG. 2, b is a cross-sectional view of a unidirectional moisture holder.
b-1 is a first layer having water permeability. b-2 is a second layer containing air and having water permeability.
b-3 is a third layer made of a water-absorbing material that can absorb and retain moisture that has passed through the first and second layers. b-4 is a fourth layer made of a material that does not transmit moisture.

As shown in FIG. 3, c is a plan perspective view of the sheet of the unidirectional moisture holding body. c-1 is the figure which installed the strip | belt-shaped body which provided the insertion hole for the hanging hook of c-2 partially for quick-drying in the 1st layer vertical direction. The number of the strips may be one, and the installation direction is preferably the vertical direction from the viewpoint of safety so that the user's limbs do not enter. Moreover, it is preferable that the size of the insertion hole is narrow so that the user's limbs do not enter as long as the hook can pass through. c-3 is a joint between the first layer and the third layer. In the unidirectional moisture retaining body construction method, it is preferable that the belt-like body is fastened by stitching the first layer and the second layer together with a peripheral bag. The shape of the unidirectional moisture holding body is not particularly limited as long as it is convenient for the user, whether it is rectangular, square or circular.

As shown in FIG. 4, d is a three-dimensional view in which b is suspended and dried. d-1 is the joint between the unidirectional material of the first layer and the waterproof material of the fourth layer. d-2 is a band-like body part insertion hole for hanging hooks. e-1 is a dotted diagram of locking members for preventing scratching.

As shown in FIG. 5, e is a rear view of c, and is a diagram in which the scuffing and locking members of e-1 are placed on the entire bed sheets in a dotted manner so as to be easily attached and detached.

As shown in FIG. 6, f is a modified example of the rear view of b according to the first embodiment, and is a diagram in which the entire surface is subjected to anti-scratching processing for preventing anti-scrubbing, and the processing method is preferably embossing or the like.

It is the figure which laid the sheet | seat of the unidirectional moisture holding body of b partially on the whole bed sheet as shown in FIG. 7 under the user waist | hip | lumbar part.

As shown in FIG. 8, in the second embodiment, h is a vehicle seat and b is installed with a unidirectional moisture retaining body, and h-2 is seated to prevent falling off from the seating surface due to lateral transfer when getting on and off. It is preferable to use a material with high stretchability so that it can be easily attached and detached during replacement, and h-1 is on the backs of the side parts of both bodies to suppress rubbing during the above. It is the figure which installed the rubbing prevention prevention locking member. Further, the shape of the retaining member is not particularly limited as long as the seat back is tilted forward and rubbed into the gap between the seating surface and the retaining member is sandwiched to prevent the falling off when getting on and off.
