Abstract:
A wound dressing laminate (1') comprises a layer (3) impregnated with an antimicrobial agent (4) inserted between an apertured wound-contacting layer (2) and an absorbent non-woven layer (5;6). Wound dressings made of the wound dressing laminate prevent infection of a wound, do not induce maceration, and absorb exudates at controlled level so as to continuously cleanse the wound bed without drying the wound. Manual cleansing during dressing changes, if any at all, is usually not necessary and significant nursing time can be saved. The laminate is manufactured using the steps of providing the layer (3) impregnated with an antimicrobial agent (4), providing an apertured wound-contacting layer (2) adjacent one side of the layer (3) impregnated with the antimicrobial agent (4), providing an absorbent non-woven layer (5) adjacent the opposite side of the layer (3) impregnated with the antimicrobial agent (4), and laminating the layers (2;3;5) together mechanically.
Abstract:
Die Erfindung betrifft eine Wundauflage (2) zur Wundbehandlung im feuchten oder feuchtnassen Milieu, mit einem faservliesbasierten Saug-/Spülkörper (4), in dem superabsorbierendes Material verteilt aufgenommen ist, wobei der Saug-/Spülkörper (4) herstellerseitig mit einer salzhaltigen wässrigen Lösung, insbesondere Ringerlösung, vorzugsweise bis zur Sättigung, beaufschlagt ist, und mit einer die äußeren Sichtseiten der Wundauflage bildenden Umhüllung (6), wobei auf der wundabgewandten Seite des Saug-/Spülkörpers (4) eine verdunstungshemmende Folienschicht vorgesehen sein kann; die Wundauflage wird dadurch verbessert, dass die wässrige Lösung eine bei pH-Werten von 4-7,5 eines typischen feuchten oder feuchtnassen Wundmilieus kationische Substanz mit antimikrobieller Wirkung umfasst, die von negativen Gruppen des anionischen superabsorbierenden Materials attraktiv angezogen wird und so innerhalb des Saug-/Spülkörpers (4) antimikrobiell wirkt, und dass die Umhüllung (6) auf der wundzugewandten Seite eine außenseitig partiell und strukturiert aufgebrachte atraumatisch wirkende Beschichtung (16) mit einem Bedeckungsgrad von höchstens 70% aufweist.
Abstract:
A method and apparatus are disclosed for dressing a wound. The apparatus comprises an absorbent layer for absorbing wound exudate, a gas impermeable cover layer overlying the absorbent layer the cover layer, comprising at least one orifice Configured to allow negative pressure to be communicated though the cover layer in at least two spaced apart regions.
Abstract:
A method and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, a gas impermeable cover layer overlying the absorbent layer and the transmission layer, the cover layer comprising an orifice connected to the transmission layer, and at least one element configured to reduce the rate at which wound exudate moves towards the orifice when a negative pressure is applied at the orifice.
Abstract:
A wound packing element is in the form of a nonwoven material, particularly an airlaid nonwoven material. Such a wound packing element, or a number ofsuch wound packing elements formed into a layered assembly, may be utilised to pack a wound cavity.The wound packing element is of particular utility in negative pressure wound therapy (NPWT).
Abstract:
There is provided herein a disparate use bandage comprising a pad portion and an elongate wrapping portion attached at an end thereof to an edge of said pad portion, said pad portion comprising an outer layer, at least one absorbent layer, an inner layer formed of a generally non-permeable material which is attached to the remainder of said pad portion in a readily removable manner.
Abstract:
Die vorliegende Erfindung betrifft Wundauflagen, insbesondere zur Behandlung von mittel bis stark exsudierenden Wunden, sowie deren Verwendung in der modernen Wundbehandlung. Diese Wundauflagen umfassen als mehrschichtige Wundauflage eine Trägerschicht, eine absorbierende Schicht sowie eine mit der absorbierenden Schicht verbundene hydrophile Wundkontaktschicht, wobei die Wundkontaktschicht ein hydrophiles Polyurethan-Elastomer umfasst.
Abstract:
The present invention provides a reinforced absorbent article that includes one or more reinforcement means. The reinforced absorbent article allows for the use of high-speed processing without machinery malfunction and downtime. In one embodiment the reinforced absorbent article is a reinforced absorbent food pad.
Abstract:
A pressure bandage for applying pressure to a target site comprising (i) a backing layer with a coating of a pressure-sensitive adhesive on a first major surface of the backing layer, and (ii) a snap-bucklable member coupled to the backing layer and capable of snap-buckling from a concave to a convex configuration after the bandage has been adhesively applied over the target site so as to apply continuous pressure to the target site so long as the bandage is worn. The pressure bandage may be positioned over a bleeding target site to apply pressure to the target site and reduce bleeding.
Abstract:
An absorbent wound care device comprising a wound contacting layer comprising an absorbent non-woven bi-component staple fibre material, said staple fibre material comprising fibres having at least one outside portion of highly hydrophilic material and least one inner core of a low- absorbing material, wherein the staple fibre material comprising fibres having at least one outside portion of highly hydrophilic material and least one inner core of a low-absorbing material constitutes above 50% of the fibrous material and wherein the absorbent material consists of mechanically intertwined fibres enables the use of an absorbent material comprising only fibres having at least one outside portion of highly hydrophilic material without having to rely on the presence of wicking fibres, which material is capable of absorbing liquid parts and slough from wound exudates without giving rise to gel blocking and also reduces of the risk of maceration due to wicking of moisture laterally in the plane of the wound to the neighbouring skin.
