Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pressure ulcer prevention mat used for diapers, lumbosacral underlays and the like.

[0002]

[Prior art]

 The applicant (inventor) previously provided a utility model registration No. 1587085 to provide a mat useful for preventing bedsores of bedridden sick people, and has been highly evaluated. The inventor of the present invention continued to have an awareness of the problem of further improvement in the long-term use of the preceding mat, and as a result of hoping for clinical practice, encountered the following two points.

That is, (a) For example, when a pressure ulcer has already occurred in the lumbosacral region and is currently in progress or for a sick person who has a sign of the pressure ulcer, when the pressure ulcer prevention mat is replaced, the pressure ulcer is first treated. Then, apply a remedy (an ointment and dry powder to prevent rashes), and then create a floating space at the place where the new mat is to be interviewed so that the pressure ulcer part where the drug is applied does not come into direct contact. Wearing clothes was indispensable from the viewpoint of alleviating the suffering of the sick and preventing the progress of pressure ulcers. The same consideration needs to be given to the part of the skin where the pressure ulcer has not yet developed but has a sign (base).

(B) Although the upper sheet of the mat is made of water absorbent material, the skin contact surface of the mat is apt to get stuffy due to sweating or wetting from pressure ulcer, and the inner polyethylene is made of waterproof material. Since the cushion mat is water repellent, the moisture and moisture inside the cushion mat also wets the upper sheet from the inside, which also tended to make it slightly uncomfortable in the rainy season. In the case of (a) above, in addition to the treatment of pressure ulcers and the formation of a floating space at the time of mat replacement, labor is required, and in the case of (b), early mat replacement is required.

[0005]

[Problems to be solved by the device]

 The present invention aims to improve the above two problems (a) and (b).

[0006]

[Means for Solving the Problems]

 The structure of the present invention will be described below with reference to the reference numerals of the embodiment drawings. The present invention relates to a pressure ulcer prevention mat formed by stacking and fixing a waterproof cushion mat 3 having a large number of these bulges 3a independently oriented to the contact side with the human body in the above-mentioned order.

The present invention also includes a drug sheet 1 containing a pressure ulcer therapeutic agent component having a release sheet 1a attached on the upper surface thereof, a water absorbent sheet 5 containing a desiccant, an upper sheet 2, and an air bulge 3a. The present invention relates to a pressure ulcer prevention mat formed by stacking and fixing a waterproof cushion mat 3 having a large number of these bulges 3a independently oriented toward the contact side with the human body in the above-mentioned order. In another embodiment, the water absorbing sheet 5 is provided between the upper sheet 2 and the waterproof cushion mat 3, or the desiccant powder particles 6 are used in place of the sheet to form flat valleys 3b between the bulges 3a. It also includes loading into.

[0008]

[Action]

 According to the present invention, the uppermost layer of the mat is provided with the drug sheet 1 containing the therapeutic agent for pressure ulcer, and the release sheet 1a is attached to the upper surface of the sheet 1, so that the pressure ulcer A of the sick person can be replaced when the mat is replaced. By applying the medicine sheet 1 to a certain area range including at least, reliable and speedy treatment is possible.

Next, a waterproof cushion mat is used to form a space g that floats in the thickness direction with respect to the mat to be laid including the pressure ulcer part A, that is, a play space g in which the pressure ulcer part A and the lower mat do not adhere to each other. A large number of bulges 3a oriented on the contact side with the human body are crushed by fingertips or stabbed by a sharp object to float a space g inside the mat corresponding to the treatment site, which is also simple and speedy. Can be realized.

Further, a water absorbing sheet 5 containing a desiccant powder inside the thickness is disposed between the lower side or the upper side sheet 2 and the waterproof cushion mat 3 of the mat, or Instead, the flat valleys of the cushion mat are filled with desiccant powder particles 6, so that the above-mentioned wetting can be sufficiently prevented even in the rainy season.

[0011]

【Example】

 (Example 1) In FIGS. 1 and 2, a drug sheet 1 having a rectangular dimension of 150 mm in length and 110 mm in width with respect to a rectangular pressure ulcer prevention mat M having a length of 300 mm and a width of 210 mm is a product as a drug component for treating pressure ulcers. The name Orsenone ointment (made by American Redery Co., Ltd.) is formed into a poultice sheet shape together with the poultice base, and the release sheet 1a is attached to the upper surface thereof so as to partially cover the central portion of the upper sheet 2. It is bonded and fixed to the upper sheet 2 by the double-sided adhesive tape 1b. The shape, size, and adhesion position of the drug sheet 1 may be determined based on the shape, size, and site statistical data of the pressure ulcer part A. As another example of the therapeutic drug component, the trade name "REFLAP" (manufactured by Eisai Co., Ltd. in Japan) can be used. The upper sheet 2 is shown as an example of a bag integrated with the lower sheet 4 in this example, and the material is a mixed non-woven fabric of cotton fibers and polyester fibers, and has good breathability, hygroscopicity, and durability.

The waterproof cushion mat 3 is composed of two upper and lower thin films 3c and 3d made of soft polyethylene or other soft waterproof material, and a hemispherical bulging part upward by air enclosed between the thin films 3c and 3d. A large number of 3a are regularly arrayed independently in the surface direction, and flat valleys 3b are interposed between the bulges 3a. The commercially available product has the trade name "Ear Cap" (made by Ube Industries), and the bulged portion 3a having a diameter of about 20 mm is easy to be crushed or stabbed and can provide reliable point support to the affected area.

In this example, the upper sheet 2 and the waterproof cushion mat 3 are in a free and individual relationship without being bonded or sewn, and the lower sheet 4 is an example of a bag made of the same material as the upper sheet 2. As shown, the waterproof cushion mat 3 is loosely inserted in this bag. As described above, the term “fixing by stacking” means not only fixing all the stacking members integrally but also maintaining the form of a single mat-like object without the stacking members being scattered as a whole. Therefore, when the cushion mat 3 and the upper seat 2 are in a fixed relationship, the lower seat 4 may be unnecessary. When the mat M of the present invention is used in connection with a diaper, the lower sheet 4 is made of a waterproof material.

To describe the usage procedure of the present embodiment, the release sheet 1a of the uppermost drug sheet 1 of the pressure ulcer prevention mat M is peeled off and the exposed drug sheet 1 including the pressure ulcer part A is attached to the periphery thereof. . The time required for this work is short, and it does not matter if you forget to bring the therapeutic agent inadvertently.

Next, in order that the bulging portion 3a of the waterproof cushion mat 3 does not directly press against the part corresponding to the pressure ulcer part A and the pain is not felt, the area including the corresponding part at least (circular, rectangular, polygonal, Corresponding to the occupying space of the bulging portion 3a within the thickness of the cushion mat 3 by crushing the bulging portion 3a with a fingertip or piercing with a sharp object such as a pin, a needle, etc. The floating space g can be formed, and as a result, when the surrounding area of the lumbosacral area W centering on the pressure ulcer area A is placed on the mat M so as to correspond to this space g, the pressure ulcer area A Also, the contact with the bulging portion 3a is avoided in and around it, and the other portions are received pointwise and elastically by the original bulging portion 3a, so that the original function of the previously registered utility model is exhibited. It will be understood that the time and effort required to crush and stab the bulging portion 3a are also small. The first embodiment corresponds to claims 1, 2, 6, and 7.

Example 2 A point different from the previous example is that a water absorbent sheet 5 containing a desiccant is inserted between the drug sheet 1 and the waterproof cushion mat 3 as shown in FIG. Except for the seat 5, the other members are the same as those in the first embodiment, and the description thereof will be omitted. The water-absorbent sheet 5 has a highly water-absorbent polymer (not shown) enclosed inside the thickness of the sheet, and the polymer directly contacts the skin. It is designed so that it is not exposed.

When the water-absorbent sheet 5 comes into contact with the skin, the water-absorbent sheet 5 removes sweat and moisture on the inner surface of the upper sheet 2 as well as perspiration in the adjacent area as well as in the adjacent area. It is released from the unpleasant feeling of wearing even in the humid rainy season or indoors. This example corresponds to claims 3, 6, and 7.

(Example 3) A point different from Example 2 is that the water absorbing sheet 5 is inserted between the upper sheet 2 and the waterproof cushion mat 3 as shown in FIG. Therefore, there are only two points that the water-absorbent polymer may be exposed on the upper surface of the sheet, and a description thereof will be omitted. This example corresponds to claims 4, 6, and 7.

(Example 4) A point different from Examples 2 and 3 is that as a water absorbing means instead of the water absorbing sheet 5, the water-absorbing cushion mat 3 with the desiccant powder particles 6 such as super absorbent polymer or zeolite is naked. Since it is intended to absorb moisture and moisture from the inside of the mat M by directly loading it in the flat valley portion 3b, the water absorption effect is stronger than in Examples 2 and 3, and the contact of the powder particles 6 with the skin is It can be easily understood that it is safe because it is not. This example corresponds to claims 5, 6, and 7.

[0020]

[Effect of device]

 As is clear from the above description, according to claims 1 and 2, the pressure ulcer treatment using the drug sheet can be performed immediately when the pressure ulcer mat M is replaced, and the drug sheet also includes the pressure ulcer and extends to the surrounding site. As a result, it is effective for treatment and prevention, and it is possible to quickly form a floating space within the thickness of the mat so that surrounding areas including pressure ulcer do not come into direct contact with the mat due to crushing and puncturing of the bulge, which causes pain to the sick person. According to claims 3 to 5, while maintaining the above convenience, it is possible to surely prevent wetting at the contact interface between the skin and the mat, and obtain a comfortable wearing feeling. Profit is added.
