DEVICE AND KIT FOR INDICATING A PH AT A LOCUS
Device comprising polyurethane material for indicating pH at a locus, preferably as indication of presence of microbes, comprising a polyurethane network having immobilised therein one or more hydrophilic copolymers, the or each said copolymer comprising:
hydrophilic monomer; and
indicator monomer, which provides an indication in response to a change in hydrophilic state of said hydrophilic monomer and/or copolymer;
characterised in that the or each copolymer further comprises one or a plurality of ionisable groups or moieties or polymerisable monomers having one or more characteristic pKa values in the range 5 to 10 and which are responsive to pH at the locus in the range pH 5 to pH 10
and in that hydrophilic state of hydrophilic copolymer is dependent on ionisation of said ionisable groups, moieties or monomers; kit and device comprising the material and process for preparation thereof; and use in detecting or sensing microbes or pH.

BANDAGE FOR ENCLOSING A LEG REGION OR ARM REGION OF A LIVING BEING
The invention relates to a bandage (100) for enclosing a leg region or arm region of a living being, said bandage comprising: an elongate, tubular bandage part (10), at least part of which has a single slit in the longitudinal direction (LR) and which is designed to elastically enclose the leg or arm region when worn; and a closure part (20) which has closure elements (22) and which is fixedly connected to one end of the slit region (B) of the bandage part in order to detachably seal the slit region (B) by connecting the adjacent ends of the slit region (B) in an overlapping manner by means of the closure elements (22, 22). According to the invention, the bandage part (10) has different compression zones (K1, K2) in the longitudinal direction (LR) which each have different radial compression strengths transverse to the longitudinal direction (L).
WOUND DRESSING
A would dressing includes an absorbent core including a top carrier layer and a bottom carrier layer, a superabsorbent substance dispersed between the top carrier layer and the bottom carrier layer and the bottom carrier layer, and a shell formed by a facing layer and a backing layer. The absorbent core is located in the shell between the facing layer and the backing layer. The facing layer and the backing layer each can include a supporting structure. The supporting structure of the facing layer and the supporting structure of the backing layer each can include an inner surface facing towards the absorbent core and an outer surface facing away from the absorbent core. The outer surface of the supporting structure of the facing layer and/or the outer surface of the supporting structure of the backing layer can be laminated with a foam layer.
Fibrin composition, method and wound articles
A method of forming a fibrin hydrogel composition is described. The method comprises forming an aqueous solution comprising fibrinogen, fibrin-forming enzyme, and a fibrin hydrogel forming salt. The fibrin hydrogel forming salt concentration is greater than or equal to the threshold concentration to form a fibrin hydrogel. The method further comprises reducing the salt concentration below the threshold concentration to form a fibrin hydrogel. In some embodiments, the aqueous solution further comprises a plasticizer. A fibrin composition is also described comprising a fibrin hydrogel having a fibrin concentration ranging from 0.1 to 10 wt-%; and a fibrin hydrogel forming salt. The fibrin hydrogel forming salt has a concentration less than a threshold concentration to form the fibrin hydrogel. The fibrin hydrogel or dehydrated fibrin hydrogel can be in various physical forms such a sheet, foam, or plurality of pieces. Also described are methods of forming a fibrin article, wound dressings and a method of treatment of a wound.
