Abstract: A method of producing a hydrophilic polyurethane foam structure containing a silver salt, chosen from the group of silver sulphate, silver citrate, silver acetate, silver carbonate, silver lactate and silver phosphate, or a mixture of these salts includes the steps of (a) providing a water phase containing a surfactant, and at least one silver salt, wherein the at least one silver salt is dispersed in the water phase; (b) providing a isocyanate-terminated polyether having functionality of more than (2); (c) mixing the water phase and the isocyanate-terminated polyether, immediately transferring the resulting mixture to a mould whereby a foam structure is obtained; and (d) drying the foam structure until it has a moisture content of at most 10% (wt). The hydrophilic polyurethane foam structure produced by the method and a wound dressing containing the foam structure are also described.

Abstract: A method of manufacturing an absorbent article in the form of a pants-type diaper or a sanitary panty starts from a flat blank which includes an elongated absorbent body (5) enclosed between two casing sheets (2, 9) which at opposing front and rear end parts of the absorbent body have side parts which extend laterally beyond the body on opposite sides thereof. The method includes the step of folding the blank about a transverse axis so that the end edges of the side parts lie edge-to-edge. The front and rear side parts of the blank which oppose one another in the folded state of the blank are joined together by a releasable and refastenable fastener (20).
Abstract: The present invention relates to a disposable surgical drape (1) that includes a layer (2) of absorbent material and a layer (3) of plastic material. According to the invention, net material (4) extends between the respective layers of absorbent material and plastic material (2 and 3) over the entire drape (1) or over parts thereof.
Abstract: An absorbent article having a front part (13; 13′), a rear part (14; 14′) and a crotch part (15; 15′) which lies therebetween. The article includes an absorbent body (1; 1′; 25) which is enclosed between an outer, liquid-impermeable casing sheet (7; 7′; 26) and an inner, liquid-permeable casing sheet (8; 8′; 27), this latter sheet lying proximal to a wearer's body in use. The article further includes on opposite sides of a longitudinal symmetry axis of the article flexible, longitudinally extending flaps (9, 10′ 9′, 10′; 28, 29), each of which is connected to the inner casing sheet along a longitudinal edge and which extends from the connected longitudinal edge in toward a longitudinal symmetry axis of the article. The flaps (9, 10; 9′, 10′; 28, 29) are joined together in the crotch part (15; 15′) of the article.

Abstract: In a method and device for applying a thread to a moving substrate, a thread is continuously dispensed to a pick-up point adjacent to the point of contact of two rotating wheels (2, 3) that are inclined towards each other. The peripheries of the wheels have fingers (7) which hook the thread and move it to one side or the other as the wheels rotate, and then deposit the thread extended between the fingers 180° from the pick-up point. Long spaces between the fingers (7) on one wheel or the other make it possible to lay the thread longitudinally (8b) or in a long diagonal line instead of merely in a lateral zigzag pattern. The method and device may be used to make an absorbent article, such as a diaper.
Abstract: The present invention relates to a surgical drape that includes a liquid-absorbent top sheet (1) and a liquid-impervious sheet (2) immediately beneath the top sheet. The liquid-impervious sheet faces towards a patient when the drape is in use. According to the invention, at least one string of hotmelt glue (5) is disposed on the surface of the drape, this hotmelt glue extending from the upper side of the top sheet, through said top sheet and bonds with the liquid-impervious sheet.
Abstract: A diaper or incontinence guard includes a waist belt (1) and an absorbent unit (2) with a front part (3), a rear part (4) and an intermediate crotch part (5). Fastener devices (9-11 and 6-8 respectively) are disposed at the front end and the rear end of the absorbent unit and can be fastened to the belt. Each of the front and rear ends of the absorbent unit (2) includes a respective central fastener device (10 and 7) that is located on the longitudinal symmetry axis (A—A) of the unit, and two lateral fastener devices (9, 11 and 6, 8 respectively) located on respective sides of the axis.
