Description

[Detailed description of the invention] This invention improves the sanitary conditions during incontinence and urination for seriously ill people, senile people, etc. who have been bedridden for a long time, and has breathable and waterproof properties that can emit the necessary notification signal at that time. It concerns the seat.

The inventor of the present invention previously proposed the invention in Utility Model Application No. 1983-9449, which is a measure against incontinence by laminating a fine thin cloth made of thin synthetic fiber monofilament on top of a coarse thick cloth made of large diameter synthetic fiber monofilament. The present invention further enables nurses to take appropriate measures immediately by electrically closing an external alarm circuit when urinating due to incontinence.

In other words, the present invention replaces the previously commonly used waterproof sheet for incontinence prevention with a mattress,
In order to prevent contamination of mats, and to improve the point that has not been considered at all in terms of improving sanitary conditions for sick people, the bed surface of the sick person, especially around the waist, is constantly maintained in a permeable state, and incontinent urine flows away. Sometimes, the upper surface is non-permeable to prevent urine from passing through to the lower surface, and the sheet is relatively diffusive in the plane direction, thereby closing the electrical alarm circuit. We have found that the laminated sheet described in the claims of the utility model registration is extremely effective.

The lower surface of the sheet of this invention is a fine thin cloth made by knitting and woven synthetic fiber monofilament with a large diameter, so it is placed on the sleeping surface and usually a bed sheet is layered on top of it to create a nightgown.
When a sick person goes to bed wearing a diaper, the thick fabric on the bottom of the sheet maintains a good ventilation interval, and since both the top and bottom surfaces are made of synthetic fiber monofilament,
There is little ventilation resistance in the vertical direction, and moisture absorption by bedding, etc. is suppressed, and the patient's skin is kept appropriately dry. The permeated urine reaches the surface of the fine, thin cloth, but unless the amount of urine is particularly large, the water is retained without passing through the grains of the hydrophobic synthetic monofilament, and its lower surface contacts the coarse, thick cloth in a small area. Therefore, it is difficult to flow down to the lower surface, and the lower surface coarse thick cloth isolates it from the surface of the mattress and prevents it from penetrating downward. The moist state of the skin surface is gradually reduced, and the ventilation state is maintained by the coarse thick cloth on the lower surface, and together with the body temperature, the skin becomes dry relatively quickly. In addition, the two conductive wires spaced apart from each other on the fine thin cloth on the upper surface are connected to an external power supply alarm circuit. The terminals are electrically connected, a notification circuit is closed, and the urination status is notified to the nurse by sounding, lighting, or transmitting wireless communication.

In the above, the coarse thick fabric knitted with large diameter synthetic fiber monofilaments is made of 5 to 12 meshes of large diameter monofilaments with a diameter of 0.5 to 1.0 mm made from nylon, polyester, polyethylene, polypropylene, polyvinyl chloride, etc. The fabric is made of a coarse mesh material with a thickness of 1 mm or more, thus forming a space for good ventilation and prevention of urine infiltration. Made of resin with a diameter of 0.4 to 0.05 mm and a fine mesh of 16 to 120 mesh, the fabric thickness is
It is a thin cloth with a thickness of 0.8 mm or less, which provides waterproof and water-retaining properties as well as breathability.As a conductive wire, it can be used as a thin metal wire such as copper or aluminum.
The thickness is approximately 0.1 to 0.4 mm, and if necessary, the surface is coated with corrosion-resistant metal such as tin or zinc, or conductive carbon fiber is used.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a partially cutaway plan view of the breathable waterproof sheet for incontinence alarm of the present invention, and Fig. 2 is a sectional view of the main part along the conductive wire in the state of use. 2 is a coarse thick cloth made by coarsely woven synthetic fiber monofilament, and 2 is a fine thin cloth made by weaving small diameter synthetic fiber monofilament, and the width, length and shape are adjusted to suit the usage conditions, and the fabric is laminated by polymerization. , its peripheral edge 3 is covered with heat bonding, ultrasonic bonding, or ear cloth, and fixed by sewing, thermocompression bonding, or the like.

4 and 4' are conductive wires that are woven through the center of the fine thin cloth 2 at intervals of 0.5 to 1.5 cm, and one end of which is connected to the plug terminal 5 fixed to the peripheral edge 3. Connected by soldering etc.

Reference numeral 6 denotes an outlet into which the plug terminal 5 is inserted, and is thereby connected to a low voltage power source alarm 7.

As mentioned above, in Figure 2, the sheet according to the present invention to which the power supply alarm 7 is connected is placed on the top surface of the mattress M, the mattress S is spread on the top surface, and the human body B is lying on it. 8 is the mattress side cloth.

Figure 3 is a partially cutaway plan view of two sets of conductive wires folded into a fine thin cloth 2 in order to expand the urination sensing area, and to accommodate changes in the urination position. At the same time, it is also possible to deal with a breakage accident of one of the conductive wires, and depending on the conditions, three or more sets of two conductive wires can be arranged.

With the above-mentioned configuration, this system forms a breathable and waterproof layer on the underside of a bedded patient, and an electrical alarm circuit is immediately closed when urinating, which contributes to the improvement of nursing and hygiene conditions, such as preventing bed sores at all times. The place is extremely large.

The breathable waterproof sheet for incontinence notification of the present invention exhibits the above-mentioned effects, and is therefore extremely suitable for incontinence prevention not only for sick people but also for infants who urinate at bedtime and people with nocturnal enuresis.
