METHOD FOR PRODUCING AN ADHESIVE-FREE WOUND CONTACT COMPOSITE MATERIAL
20200054781 · 2020-02-20 ·

The invention relates to a process for producing a composite material for wound dressings, comprising the following steps: (I) providing a first film, having a first film surface and a second film surface running virtually parallel to the first film surface; (II) mixing an NCO-terminated polyurethane prepolymer with at least water to give a polyurethane prepolymer/water mixture, (III) applying the polyurethane prepolymer/water mixture to at least one part of the first film surface to form a layer, the layer having a first layer surface which is in contact with the first film via at least one part of the first film surface, and having a second layer surface which runs virtually parallel to the first layer surface; (IV) covering at least one part of the second layer surface with a further film,
wherein the bond strength between the first film and the layer and also between the layer and the further film is greater in each case than the tensile strain at break of the layer.

The invention further relates to a composite material produced by the process of the invention and also to a wound dressing comprising such a composite material and also to the use thereof in a wound dressing for improving the absorption of wound secretion and the distribution of secretion in the wound dressing.

Magnetic dressing and preparation method and use thereof

The present disclosure provides a magnetic dressing and a preparation method and use thereof, belonging to the technical field of pharmaceutical preparations. The magnetic dressing includes a magnetic layer, a drug-loading layer, and a protective layer that are stacked in sequence, where the magnetic layer includes polyvinyl alcohol, gluten, and iron particles. In the present disclosure, a swallowed magnetic dressing is controlled by an external magnetic field, and the magnetic dressing is moved to a pathological position by changing a direction of the external magnetic field; after the external magnetic field is removed, the magnetic dressing changes from a ring to a sheet, thereby completing attachment of an entire lesion surface to complete treatment by autonomous drug release.

MULTI-LAYERED WOUND DRESSING AND METHOD OF MANUFACTURE

A multi-layered wound dressing including a fibrous absorbent layer for absorbing exudate from a wound site. The wound dressing also includes a support layer configured to reduce shrinkage of at least a portion of the wound dressing.
