Abstract:
System for draining fluid from a wound, which system comprises an enclosure for enclosing the wound, a drainage conduit (104) for connecting a wound site within the enclosure to a suction source, a pressure communication conduit (102) providing a communication between the wound site and a pressure sensing element. The drainage conduit (104) and the pressure communication conduit (102) extend coaxially, so that one of the conduits is in the form of an annular passage surrounding the other conduit.
Abstract:
The present application discloses biodegradable polymers, to porous and other materials comprising such polymers, and to various medical uses of such materials, including use as a scaffold for supporting cell adhesion or the in-growth for regeneration of tissue. The polymer is of the formula A-O-(CHR 1 CHR 2 O) n -B wherein A is a poly(lactide-co-glycolide) residue, the molar ratio of (i) lactide units [-CH(CH 3 )-COO-] and (ii) glycolide units [-CH 2 -COO-] in the poly(lactide-co-glycolide) residue being in the range of 80:20 to 10:90, B is either a poly(lactide-co-glycolide) residue or hydrogen, C 1-6 -alkyl or hydroxy protecting groups, one of R 1 and R 2 is hydrogen or methyl, and the other is hydrogen, n is 10-1000, the molar ratio of (iii) polyalkylene glycol units [-(CHR 1 CHR 2 O)-] to the combined amount of (i) lactide units and (ii) glycolide units in the poly(lactide-co-glycolide) residue(s) is at the most 14:86, and the molecular weight of the copolymer is at least 20,000 g/mol.
Abstract:
System for draining fluid from a wound site at a skin surface of a living being. The system comprises a suction source, a drainage tube for conveying wound exudate away from a wound at the wound site, the drainage tube being in fluid communication with the suction source at one end thereof and with the wound site at the other end thereof, and an attachment device for connecting the drainage tube to the wound site, the attachment device forming or being part of a sealing enclosure at the wound site. The attachment device comprises a stationary part arranged to be fixed to the living being's body, a rotary part interconnecting the tube and the stationary part, the rotary part being rotatable relative to the stationary part.
Abstract:
We add discontinuous regions of Extra Cellular Matrix (ECM) to a biodegradable scaffold. Hereby it is possible to combine the range of physical properties the scaffold can offer with the reconstructive properties of the ECM. The optimal amount of discrete ECM material for each application is disclosed and this concentration is equally distributed in the dressing hence avoiding unnecessary high concentrations of ECM. In addition to the effect of the ECM, the porous structure of the base material provides the cells with a structure for in-growth.
Abstract:
The invention relates to a foam dressing with a bevelled edge and where the density at the edge is higher than the density at the central part of the foam. The high density at the edges causes gel blocking of the wound exudate thereby preventing leakage of exudate through the edges. In a preferred embodiment the foam dressing is non-adhesive. The foam dressing may have a water-impervious backing layer, which extends all the way over the top of the dressing and down to the wound-contacting surface. The wound dressing is particularly useful in treatment of venous ulcers in connection with compression bandages, as the bevelling of the edges markedly reduces the indentations in the leg following use of this dressing when compared to a dressing with straight edges.
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.
Abstract:
A medical dressing comprising a complex of silver and being capable of releasing antimicrobial silver ion activity, said complex comprising silver and a transition element of Group IV of the periodic system of elements enables a controled release of silver ion activity to a wound bed.

Abstract:
A wound dressing comprising a backing layer and an absorbent layer, wherein the absorbent layer comprises a wound facing surface and a non-wound facing surface, said absorbent layer comprises discrete foam pads covering at least 50% of the wound facing surface of the absorbent layer and wherein the non- wound facing surface of the foam pads are attached to the backing layer. The structure of the dressing renders it possible for the foam to expand during wetting without changing the external dimensions of the absorbent layer substantially.
