Description

AN ABSORBENT SANITARY PRODUCT. IN PARTICULAR A TOWEL FOR INCONTINENCE. DIAPER OR SIMILAR FIELD OF THE INVENTION The invention relates to an absorbent medical device, in particular an incontinence towel, diaper or the like, with the aspects mentioned in the preamble of claim 1.

BACKGROUND OF THE INVENTION Generic medical devices are well known, and usually provided with a liquid impervious protective layer of underwear, produced for example from a thin layer of polyethylene which makes contact with the wearer's clothing. Furthermore, it is provided with a cover layer that makes contact with the user, permeable to liquids, for example a hydrophilic nonwoven fabric. An absorbent body is inserted between these two layers, which usually consists of cellulose fluff comprising superabsorbent particles dispersed therein. The absorbent body can be of various shapes, for example it is strictly rectangular, or to better fit the anatomical needs, it is of an hourglass shape, in such a way that the absorbent body in the area of nesga has a minimum width and runs straight towards the front and towards the posterior end, parallel to the longitudinal direction of the sanitary product. Also, modern sanitary products are equipped with two so-called barriers, which run on each longitudinal side of these products, the lower end portion or foot of these barriers being attached to the cover layer and the head portion being provided. with elastic straightening elements, for example by means of elastic rubber threads. These barriers substantially improve the protection against runoff of the relevant medical devices. Usually, the barriers are straight in the longitudinal direction of the common medical devices, it being possible to provide barriers that are relatively close to each other, and that run in the absorbent body over their total length, even in the shrinkage area of the sanitary product. . Other barriers are known that are still straight, but placed closer to the sides, thus extending, at least in the shrinkage area of the sanitary products, along the outer side of the absorbent body at the projecting edges of the absorbent body. the protective layer of the underwear and the cover layer interconnected there. The above-mentioned barriers, which are relatively close to each other, have the disadvantage that a considerable portion of the absorption surface of the absorbent body falls near the range of the barriers, and therefore can not be used for direct absorption of the barriers. body fluids. Also, this disadvantage applies to those sanitary products that have barriers placed closer to the sides, since a considerable portion of the surface of the absorbent body is also located on the sides of the barriers. Another disadvantage of common sanitary products is that the barriers can bend backwards in an uncontrollable manner, for example to the outside, which causes a considerable loss of sealing efficiency. The solution of the state of the art that goes ahead with this deficiency, consists in that the barriers are bent inwards in the area of their longitudinal ends, in whose position they are glued on the cover layer (in this way called descending union). A particular defect of the common incontinence towels with barriers, resides also in that particular incontinent patients who are bedridden tend to lie on the barriers, which can cause pressure marks and in the worst cases ulcers. decubitus. Proceeding from the aforementioned problems of the state of the art, it is an object of the present invention to improve a generic type absorbent sanitary product in such a way that the barriers can complete their sealing function in an optimum manner, without deteriorating the absorbent capacity of the absorbent body and the comfort of use. This object is achieved by the aspects cited in the characterizing part of claim 1. According to the teachings, it is a particularly ingenious profiling of the longitudinal edges of the absorbent body, which in combination with the curved course of the lower end or foot of the barriers parallel to said longitudinal edge, which will lead to special advantages. Tests have shown that the indicated profiling results in a high comfort of use and a good absorbent capacity, because a particularly wide width of the absorbent body is available, before and behind the area of gullet due to the maximum of the width according to the invention. This maximum width also increases the comfort of use, primarily because the edges of the absorbent body are placed far to the sides of, especially, the exposed body parts of bedridden patients, where the body pressure has already been greatly decreased. that rests on the mattress. In addition, the barriers take the optimal course since their lower end or foot follows the associated longitudinal edge of the absorbent body, in such a way that the barriers automatically stop vertically in the shrinkage area, thus optimally placing an area of gorge. of the user. This guarantees a good sealing function. With the course provided with the absorbent body and the lower end or foot of the barriers for both ends, the barrier automatically bends inward and forms a type of bag, which shows that it is optimal with respect to the acceptance of body fluids and excreta. This will be explained in detail, taken in conjunction with the exemplary mode. In summary, it can be said that the absorbent body and the barriers have a shape that meets the physical requirements and guarantees of a perfect fit and tightness of the absorbent medical product.

BRIEF DESCRIPTION OF THE DRAWINGS Other aspects, details, advantages and preferred embodiments of the present invention will become apparent from the subclaims and the following description of an example of the embodiment, taken in conjunction with the drawings in which Figure 1 is a perspective view. of an incontinence towel according to the invention, and Figure 2 is a diagrammatic cross section according to line II-II of Figure 1.

DETAILED DESCRIPTION OF THE INVENTION As can be seen from the drawings, the incontinence towel is provided with a liquid-proof underwear protective layer 1 of a thin polyethylene film that makes contact with the wearer's clothing. A liquid-permeable cover layer 2 of hydrophilic nonwoven fabric is provided that faces the wearer's body. An absorbent body 3 is inserted between said layers 1 and 2, consisting of a base pad 4 facing towards the protective layer 1 of the underwear, and a cover pad 5 attached to the top of the base pad 4 , and facing towards the cover layer 2. The base pad 4 consists of cellulose fluff, while the cover pad 5, as in this way called "nest of swelling particles", can for example be a nonwoven material. placed in air, mixed with superabsorbent particles not shown explicitly. Other combinations of material are known from the state of the art, and can also be used. As seen in particular from Figure 2, the edges of the protective layer 1 of the underwear and of the cover layer 2, project from the absorbent body on the sides and are interconnected in the projecting areas by the layers of adhesive 6. Also, these layers of glue 6 extend between the protective layer 1 of the underwear and the base pad 4 on the one hand, and the cover pad 5 and the cover layer 2 on the other hand. The structure of the incontinence towel and the materials described so far are completely common and do not require additional explanations. On the cover layer 2, the barriers 7, 7 'are provided on each of the longitudinal edges, whose barriers 7, 7' consist of a narrow strip of hydrophobic nonwoven fabric. The lower end or foot 8 of each barrier 7, 7 'is formed as a marginal strip of the inwardly chamfered barrier, which is durably joined to the cover layer 2 by a layer of glue. The lower end or foot 8, chamfered inwards, supports the rectangularly straightened position of the barriers 7, 7 ', shown in Figure 2. In the upper part 10 of the barriers 7, 7', the marginal strip constituting this one it is folded backwards and encloses an elastic thread 11, which is stretched over the total length of the barriers 7, 7 'in its longitudinal direction. The bent upper part 10 of the barriers 7, 7 is held by means of another glue connection 12, which also holds the elastic yarn. The elastic yarn 11 serves to straighten the barriers 7, 7 'in a manner that will still be explained in detail. Figure 1 shows that the absorbent body 3 is shrunk in the area of the base pad 4, such that the absorbent body in the area of nesga 13 has a minimum width B. Between this area of shrinkage 13 and the front and the trailing end, 14 and 15, the absorbent body 3 now has a maximum M of width B. By directing the front and the trailing end 14 and 15, the absorbent body 3 gradually decreases in the width B. The longitudinal edges 16 and 16 * of the absorbent body 3, ie of the base pad 4, therefore describe a wavy line, starting from the front end 14, forming a convex area 17, the concavely bent area 13 and another convex area 18. As shown in FIG. perceived from Figures 1 and 2, the lower end or foot 8 of each barrier runs parallel to the associated longitudinal edge 1616 'of the absorbent body over the total length of the incontinence towel and has a curved configuration. So the lower end or foot 8 follows the course of the related longitudinal edge curve 16, 16 'of the absorbent body 3. The lower end or foot 8 of the barriers 7, 7' is placed in the immediate vicinity of the associated longitudinal edge. 16,16 'of the base pad 4 in the latter, which means within the longitudinal edges 16,16'. The optimum maximum space between the lower end or foot 8 and the longitudinal edge 16,16 'must be 10 mm. Figure 1 also shows that the elastic threads 11 in the barriers 7, 7 'have a special effect due to the course of the lower end or foot 8 of the barriers 7, 7'. By means of these elastic threads 11, tensile forces Z are exerted on the barriers 7, 7 ', with the effect that the upper part 10 of the barrier 7, 7' is being shortened in the longitudinal direction. This can be noticed by the shirring in the upper area. Due to this shortening, the upper part 10 is located in the convex areas 17, 18 inside the lower end or foot 8 of the barriers 7, 7 ', and in the outer gorge area. In the maximum area M of the width B of the absorbent body 3, that is to say in the front and rear of the area 13 of the barriers 7, 7 'will bend skillfully inwards and form a type of bag 19. To achieve this, it is sufficient to stick the longitudinal ends 20 of the barriers 7, 7 'only in the area of the lower end or foot 8 to the cover layer 2. The previously mentioned descending junctions can be unattended, which facilitates the production of the object of the invention . In addition, the tensile forces Z pull the upper ends 22 in the longitudinal direction of the towel inwards, such that the end edges 23 of the barriers 7, 7 'come out relatively flat and at an acute angle towards their ends. lower or feet. In the area of nesga 13 the tensile forces Z of the elastic threads 11 have the effect that the barriers 7,7 'automatically take a vertically rectangular position, which results in excellent sealing aspects. As is apparent from Figure 1, the cover pad 5 of the absorbent body 3 has a rectangular shape and its straight longitudinal edges 21, 21 'clearly fall within the longitudinal edges 16, 16' of the base pad 4, and especially of the course lines of the upper parts 10 of the barriers 7,7 '.
