Disposable absorbent cross member.

Object of the invention

The present invention concerns a disposable absorbent cross member, with adjustable wings, comprising an absorption surface that occupies practically the entire width of the bed, so as to avoid unprotected areas, and which can be placed above the bottom sheet, protecting both mattress and sheet, and avoiding the contact of the wings with the user's skin. Background of the invention

Adjustable waterproof crossings with single-use wings, recommended to keep the bed, wheelchairs, etc., of those people who must remain for a long time in them are known in the current state of the art. These adjustable wings with wings usually provide hygiene, safety and comfort to the user, so that in case of incontinence or moisture, the protector absorbs it, leaving the surface dry and clean. In addition, since they fit the bed, they prevent unwanted displacement and wrinkle formation, thus ensuring greater user comfort.

The cover of the absorbent core of the adjustable crossings with wings is usually approximately 60 centimeters, which assuming a bed of 90 centimeters, would remain 15 centimeters uncovered on each side. These crosspieces have a wings, preferably plastic, adjustable on each side, which allow adjustment to the bed and facilitate placement. These wings, as the absorbent core does not cover the entire surface of the bed, would be in contact with the user's skin, resting a part of the wings on the surface of the bed, and with the associated problems that this entails in terms of comfort , cleaning and possible damage to the skin.

In an example of a practical embodiment of the wings with wings existing in the state of the art, Figure 3 has been shown. There are adjustable wings with wings where the absorbent surface, consisting of a core, of cellulose or similar liquid retainer, only It covers a central area of the bed, without occupying the entire width of the bed (see Figure A). These crosspieces comprise two lateral wings, which once deployed, can be fixed under the mattress like a normal sheet. A waterproof base prevents transfers, making the sheets stay clean and dry. In this way, a hygienic protector is obtained that fi lters and insulates moisture, but due to the width of the absorbent core, which leaves free space uncovered on the surface of the bed, there are risks of leaks. In addition, the adjustable wings remain in contact with the user's skin, without providing all possible protection and comfort.

At present, and mainly due to its greater technological complexity, there are no cross-members with adjustable wings whose upper layer of cellulose and non-woven occupies the entire width of a single bed (usually between 80 and 90 cm, leaving an area of the wings of adjustable plastic that rests on the surface of the bed, the greater the width of the cellulose blanket, the more complexity it entails.For this reason, current crossings are usually placed on the mattress and under the sheet, with the protector, in direct contact with the patient, without protecting it against spots of body fluids.

The main objective of the absorbent crossings is to protect the sheets and bed from possible liquid leaks that may occur in the absorbent worn by the user. Traditionally, absorbent crossings have had a cellulose weight between 100 and 200 g / m2, the most common being between 150 and 170 g / m2, as this provided the user with a perception of greater protection. However, since the losses are not usually abundant, since the user, as a rule, usually wears an incontinence absorber, the traverse is changed even leaving most of the inner cellulose unused, with the consequent waste of material. Description of the invention

The present invention solves in a fully satisfactory manner the problems set forth above. It consists of an absorbent cross member so that the coverage of the wide bed is superior to the actual crossings, so that there is no contact of the patient's skin with the wing material. In this way, with the increase in the mentioned protection width, the cross member can be placed on the bottom sheet of the bed, fulfilling its functionality of being adjustable and without limiting the contact of the plastic with the patient. In addition, it protects sheet and mattress from possible spots of body fluids

or the like, the user being isolated from the waterproof plastic layer of the passenger.

The absorbent cross member proposed by the invention contains a weight of absorbent cellulose that can vary between 30 and 100 g / m2, much lower than currently existing crossings. In this way, the cellulose fibers suffer less compaction, preventing them from sticking out, and providing greater softness to the user's touch. In addition, since cellulose consumption is lower, less waste material is generated per unit, with the consequent reduction of environmental impact.

The cellulose layer can be substituted or combined with any other material with absorbent properties, such as tissue, superabsorbent polymers or preformed cores.

The wings, which are generally made of plastic material, can be replaced by another, such as non-woven, which allow them to be attached to the bed, so that the absorbent cross member does not move. In addition, these wings could be applied independently to the absorbent core, by means of a "multipieza" process, that is, by joining them independently to it by means of glue, pressure, heat sealing or other joining systems. Description of the drawings

The present invention concerns a disposable absorbent protector, intended to be placed on the surface of the bed, above the bottom sheet, so as to protect both mattress and sheet.

The protector of the invention is primarily intended for the absorption of incontinence liquids, so that it occupies practically the entire width of the bed, avoiding user contact with areas without such protection.

The proposed invention comprises an upper layer (2) of hydrophilic non-woven material, an inner absorbent layer (1), and a lower layer of impermeable plastic material covering the entire mantle of the absorbent layer. On the sides it has wings (3, 3 ’), which fit the sides of the bed (4).

In view of Figure 2 it can be seen that L1 is the width of the upper layer (2) of nonwoven plus the inner layer (1) of absorbent material, while L2 is the total width of the bed. L2 is centered on the width of the bed, leaving the same unprotected space on one side and another, if it exists, this space being practically invaluable. The particularity of the invention resides in the absorbent core cover, where the width L1 of the upper layer (2) of non-woven plus the inner layer (1) of absorbent material occupies at least 93% of the width of the bed ( 4) L2. This prevents the existence of areas of the wings (3, 3 ’) in contact with the user, in addition to avoiding those lateral areas where protection for other types of absorbent does not reach. In addition, the protector of the invention allows its placement above the bottom sheet, protecting both mattress and sheet.

The inner absorbent layer (1), preferably is made of cellulose, being able to incorporate superabsorbent particles. The weight of cellulose is between 30 and 100 g / m2, this value being lower than for other absorbents known in the state of the art. In this way, greater comfort is achieved for the user and savings in waste material.

The wings (3, 3 ’) are of any material that allows them to be attached to the bed (4), preferably plastic or non-woven. These wings can be part of the protector so that the assembly forms a single piece, or they can be applied independently to the central body of the absorbent, joining them by means of glue, pressure, heat sealing or any other appropriate similar.
