Description

The present invention relates to a dressing material for covering the breast, which is an affected part, and its surroundings.

As breast cancer progresses, it may develop cancerous skin ulcers. A cancerous skin ulcer is an ulcerated state of cancer that has infiltrated or metastasized to the skin, and is accompanied by exudate, odor, severe pain, and the like.

Therefore, in order to suppress irritation to cancerous skin ulcers and absorb exudate to prevent leakage, sanitary napkins and urine absorbing pads (see, for example, Patent Document 1) are used to treat the affected area. Covering the chest is practiced.

Japanese Patent Application Laid-Open No. 2001-145661

However, not only does the location and size of cancerous skin ulcers differ among breast cancer patients, but it is also difficult for sanitary napkins and incontinence pads to follow the shape of the bump in the area where the absorbent material is provided. Therefore, there is a problem that the covering state tends to be insufficient, and the effect of suppressing the leakage of the exudate is low.

In view of the above points, the present invention is capable of protecting the affected area by covering the breast including the affected area and the chest including its surroundings according to the shape thereof, and sufficiently suppressing leakage of exudate from the affected area. An object of the present invention is to provide a dressing suitable for covering cancerous skin ulcers associated with breast cancer.

In order to achieve such an object, the present invention provides a dressing material for covering the breast including the breast and its surroundings, comprising an absorbent material capable of absorbing exudate and a liquid applied to the skin of the breast including the breast and its surroundings. It is composed of a permeable skin contact sheet and a liquid impermeable outer sheet polymerized on the skin contact sheet via the absorber, and is further contracted to be stretchable and formed under the breast. a breast containing portion having a gathered portion that abuts against the outer surface of the chest of the breast, provided only at the lower edge, and having no gathers provided at the upper edge, and substantially corresponding to the raised shape of the breast with the gathered portion as the lower edge; A fold is formed along the lower edge of the absorber so that it can be folded toward the skin contact sheet. An accommodation part is formed .

According to the present invention, when covering the breast including the breast and its surroundings, the breast accommodating portion can cover the breast so as to substantially correspond to the raised shape of the breast. Moreover, the gathered portion forming the lower edge of the breast accommodating portion abuts against the outer surface of the chest below the breast to reduce the occurrence of a gap, thereby suppressing leakage of exudate.

As described above, according to the present invention, it is possible to protect the affected part by covering the affected part of the breast including the breast and its surroundings according to the shape thereof, and to sufficiently suppress leakage of exudate from the affected part. be able to.

Moreover, in the present invention, it is preferable to provide an extension part that is continuous with the breast accommodation part and that can cover a part of the back from the armpit.

By providing the extension part, it is possible not only to cover a wider area and efficiently absorb the exudate, but also to prevent leakage of the exudate from the back even if the exudate reaches the back. can be well suppressed. In addition, by connecting the extension part to both the left and right sides of the breast accommodating part, the back side can be covered regardless of whether the affected part is on the left or right side, which improves usability.

Moreover, in the present invention, it is preferable that the outer sheet has a color similar to that of the skin in appearance. Thereby, the wearing state of the dressing material can be made inconspicuous.

FIG. 2 is an explanatory plan view showing the gathered dressing of the present embodiment from the skin contact sheet side. FIG. 3 is an explanatory cross-sectional view taken along line III-III of FIG. 2; BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view showing the front appearance of the gathered dressing of the present embodiment in use. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory side view of the outer appearance of the gathered dressing of the present embodiment in use.

One embodiment of the present invention will be described based on the drawings. The gathered dressing 1 shown in FIG. 1 is a dressing material of the present invention, and is used to cover the affected breast of a breast cancer patient and its surroundings, as will be described later.

As shown in FIG. 1 , the gathered dressing 1 includes a gathered portion 2 formed along the lower edge and a breast accommodating portion 3 located above the gathered portion 2 . The gathers 2 are elastic and flexibly stretchable. The breast accommodating portion 3 is formed into a three-dimensional shape (substantially dome shape) by the gathered portion 2 in the contracted state. Extension portions 4 are provided on both sides of the breast accommodating portion 3 . As shown in FIG. 2, the gathered dressing 1 has a rectangular shape in a plan view in an unfolded state in which the gathered part 2 is stretched.

The gathered dressing 1 is composed of a skin contact sheet 5, an outer surface sheet 6, and an absorbent body 7 provided between the two sheets 5 and 6, as shown in FIG. As shown in FIG. 2 , the skin contact sheet 5 and the outer sheet 6 have areas larger than the absorbent body 7 .

The skin contact sheet 5 is a liquid-permeable sheet that allows liquid to pass therethrough, and is, for example, a non-woven fabric made of PP (polypropylene), PET (polyethylene terephthalate), PE (polyethylene), or the like.

The skin contact sheet 5 can also be made of a material that is difficult to adhere to the skin, such as a polyurethane film.

The skin contact sheet 5 may be a perforated nonwoven fabric or perforated film having a plurality of perforations to facilitate absorption of viscous bodily fluids.

The outer sheet 6 is a hydrophobic or liquid-impermeable sheet that does not allow liquid to permeate, and is, for example, a film-like sheet such as PE, or a non-woven fabric bonded to the outer surface of the film.

When the outer sheet 6 is in the form of a film, it preferably has moisture permeability.

Further, as shown in FIG. 3, the outer sheet 6 has a colored layer 8 on one side thereof (the side facing the absorber 7 in this embodiment). When the outer sheet 6 is viewed from the outside, the colored layer 8 is transmitted through the outer sheet 6 and has a color similar to the skin. The outer sheet 6 may have a color similar to that of the skin, for example, the nonwoven fabric forming the outer sheet 6 may be colored.

When the colored layer 8 is provided, the colored layer 8 is formed larger than the absorber 7, is made of a moisture-permeable film such as PE, and the outer sheet 6 is made of non-woven fabric, thereby preventing leakage of liquid from the outer sheet 6 and maximizing Since the outer surface is made of non-woven fabric, it feels good on the skin.

The skin contact sheet 5 and the outer surface sheet 6 are joined so as to surround the absorber 7 . The absorber 7 is made of a material that allows permeation and retention of liquid such as exudate. preferred.

Also, the absorber 7 can contain a deodorant.

As shown in FIGS. 2 and 3, it is preferable that a fold a be formed along the lower edge of the absorbent body 7 so as to be bent toward the skin contact sheet. The breast containing portion 3 is easily formed by bending the absorbent body 7 along the fold a.

Examples of methods for forming the fold a include grooves and embossing. Moreover, the fold a does not necessarily have to be formed over the entire length of the absorbent body 7, and may be formed over the same length as the elastic member 9, for example.

The gathered portion 2 is maintained in a contracted state by an elastic member 9 such as a rubber thread interposed between the skin contact sheet 5 and the outer sheet 6 .

When the colored layer 8 is provided as shown in FIG. 3, the elastic member 9 is sandwiched between the skin contact sheet 5 and the outer sheet 6 where the colored layer is not located, in order to improve the stretchability of the elastic member. preferably

It is preferable that the elastic members 9 are located inside the side edges of the absorbent body 7 . If the elastic member 9 is positioned outside of both side edges of the absorbent body 7, since the relevant portion consists only of the skin contact sheet 5 and the outer surface sheet 6, the relevant portion shrinks and bends inwardly, resulting in poor usability. gets worse. By locating the elastic members 9 inside the side edges of the absorbent body 7, it is possible to prevent unnecessary contraction of the portion where there is only the skin contact sheet 5 and the outer surface sheet 6. - 特許庁

In this embodiment, in the unfolded state shown in FIG. 2, the size of the whole (the skin contact sheet 5 and the outer sheet 6) is about 23 cm in width (dimension in the height direction) and about 23 cm in length (dimension in the lateral direction). 50 cm, and the size of the absorbent body 7 is about 15 cm wide and about 34 cm long.

The gathered dressing 1 of this embodiment is used as shown in FIGS. That is, as shown in FIG. 4, a gathered dressing 1 is applied so as to cover the chest of a patient with cancerous skin ulcer due to breast cancer and its periphery.

At this time, as shown in FIG. 5, the gathered part 2 abuts against the chest outer surface skin below the breast so that a small gap is generated. Moreover, since the breast accommodating portion 3 positioned above the gathered portion 2 has a three-dimensional dome shape, the affected breast can be covered along the raised shape.

As a result, the absorber 7 of the breast housing part 3, which is three-dimensionally deformed substantially corresponding to the protruding shape of the chest, can efficiently absorb and retain the exudate associated with the cancerous skin ulcer arising from the affected chest. can. Moreover, at the position below the breast housing part 3, the gathers 2 are in close contact with the skin at the position below the breast, which is the affected part, so that it is possible to suppress leakage and flow of exudate.

Further, since the extension part 4 is connected to the breast accommodation part 3, the extension part 4 covers part of the patient's back from the armpits, as shown in FIG. As a result, for example, even if the patient lies on his or her back, exudate generated from the affected chest region can be prevented from flowing out to the back side.

The extension part 4 may cover a part of the back side, and since the back side does not have the unevenness of the breast, it is better not to arrange the elastic member 9 so that the gather part 2 is not formed in the extension part 4. preferable. That is, the extension part 4 is composed of the skin contact sheet 5 , the outer sheet 6 and the absorbent body 7 .

Further, the external sheet 6 is provided with a colored layer 8 as a structure having a color similar to the skin in appearance, so that the wearing state of the breast pad 1 becomes inconspicuous and the breast pad 1 can be worn without resistance.

The gathered dressing 1 is manufactured after undergoing an ethylene oxide gas sterilization process to reduce the risk of infection in the affected area.

Moreover, the size of the gathered dressing 1 is not limited to that of the present embodiment. A plurality of gathered dressings of various sizes that can correspond to the size of the affected area are prepared.

Moreover, it is preferable that the gathered dressing 1 of the present embodiment is provided with the gathered part 2 only at the lower edge and does not have the same gathered at the upper edge. If the upper edge has gathers, the upper edge side will also have a three-dimensional shape. By not providing gathers on the upper edge, the breast accommodating part 3 becomes a three-dimensional shape as shown in FIG. can.

Moreover, although the gathered dressing 1 of the present embodiment is provided with the extension part 4, the extension part may not be provided when the affected area is small. However, regardless of the size of the affected area, the provision of the expansion section 4 dramatically improves the effect of suppressing the leakage and flow of the exudate.
