A method of making a patch comprising the steps of (1) providing a carrier material; (2) coating an underside of the carrier material with a suitable non-UV-curable acrylic adhesive, the adhesive being a solution of a polyacrylate in an organic solvent or solvent mixture, the solvent or solvent mixture being used in an amount of from 25% to 70% by weight; (3) assembling the patch; (4) forming a grid structure on the patch so that it comprises a plurality of intersecting strips. According to the invention, the adhesive is applied at a temperature of 90 C. to 120 C. for a time of 5 s to 60 s, and before and/or after the application of the adhesive, the patch is activated by repeated irradiation of the underside by ultraviolet light.

A system or device for skin closure comprises an elastic flat flexible tape elongated along a longitudinal axis and having a lower side and an opposing upper side, said tape having a pressure sensitive adhesive on at least a portion of the lower side, said tape having a plurality of openings arranged side-by-side with spaces between said openings oriented across the longitudinal axis.

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.

The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue grasping elements to apply a wound closing force to the tissue.

A wound care system comprising a single-layer arrangement of mutually parallel capillary membranes with a porous, semi-permeable wall, a lumen and at least one open end. The capillary membranes are connected to one another by connection elements to form a mat and are held at a distance from one another by the connection elements.

A wound dressing system having a capillary membrane system arranged in a pouch-shaped wound dressing that is closed at its outer edge. The pouch-shaped wound dressing having an upper face, a lower face, and an interior formed from planar materials with the lower face permeable to fluids. The capillary membrane system is arranged into the interior of the pouch-shaped wound dressing.

Device for the recovery of cell-free serum from whole blood, comprising a blood bag for the reception and the coagulation of the whole blood into a solid fraction and into a fluid containing a serum, wherein the blood bag has an outlet and a barrier in the area of the outlet which is suitable for retaining at least a major portion of the solid fraction and for the passage of said fluid, a filter module which is fluidically connected to the blood bag via the outlet, comprising an interior in which a semi-permeable membrane is arranged which subdivides the interior into a retentate space and a permeate space and allows the separation of the fluid into a serum as a permeate and into a retentate in which possible particulate components contained in the fluid remain, wherein the filter module has an inlet device for introducing the fluid into the retentate space and a permeate outlet for discharging the serum from the permeate space, and at least one receiving container for serum, comprising an inlet opening which is connected to the permeate outlet of the filter module via a connecting line.

Method for the recovery of cell-free serum from whole blood, wherein the method can be carried out by means of the described device.

A system or device for skin closure comprises an elastic flat flexible tape elongated along a longitudinal axis and having a lower side and an opposing upper side, said tape having a pressure sensitive adhesive on at least a portion of the lower side, said tape having a plurality of openings arranged side-by-side with spaces between said openings oriented across the longitudinal axis.

A support for application to a body area. The support has a network of flexible non-porous tubing interlaced at a plurality of junctions to form a lattice structure. The lattice structure includes apertures to allow for the flow of air and water to the body area. At least one liquid is contained within the network of flexible non-porous tubing and is configured to transform into a solid when acted on by an external stimulus. A padding layer is secured to an internal surface defined on the lattice structure. The padding layer further includes apertures corresponding to the lattice structure apertures such that the flow of air and water to the body area is not impeded by the padding layer.

The present invention relates to free-form structures made by additive manufacturing, and methods for the manufacture thereof. The rigid free-form structures comprise a lattice structure which is impregnated by a polymeric or other material. The rigid free-form structures may be used in wound treatment, e.g., as a facial mask.
