A wound care device for the treatment of wounds is disclosed by means of atmospheric negative pressure in the wound region, including a wound-covering element that can be attached to the skin of a patient as well as a connection device for the suctioning of fluid media, wherein the wound-covering element includes a window that can be opened, which window is arranged on the wound-covering element by means of a gas-tight closure.

The present invention relates to microclosures and methods for treating microwounds in the skin (e.g., after incising or excising tissue portions from a subject). Exemplary microclosures include a material having at least one dimension of from about 10 um to about 1 mm after application to a microwound. The microclosure maintains a first compressive force when applied to the microwound.

A wound dressing comprising a layer in the form of a strip and comprising gel-forming fibers, the strip having longitudinal lines of stitches formed from a thread and transverse lines of stitches formed from a thread.

A chemically modified cellulosic fibre or filament having a moisture content of at least 7% by weight obtained by a process comprising the steps of (i) obtaining cellulosic fibres or filament and chemically modifying the cellulose by substitution to increase its absorbency; (ii) washing the fibres after step (i) in a mixture comprising water and up to 99% by weight of water-miscible organic solvent; (iii) drying the fibres to a moisture content of at least 7% by weight.

A wound dressing is in the form of a strip or a ribbon. The strip or ribbon is made of gel-forming fibers and has longitudinal lines of stitches formed from a thread and transverse lines of stitches formed from a thread.

Glass-based particles of a biocompatible material which comprises 40 to about 80 wt % borate (B.sub.2O.sub.3) intermixed into a carrier which is an ointment, cream, or surgical glue.

A device for promoting healing of an injury in a living being is provided. Such device is based upon an injury covering portion, which portion comprises an electroactive polymer, such as poled polyvinylidine difluoride (PVDF) or a copolymer of PVDF. The electroactive polymer has either pyroelectric properties, piezoelectric properties, or both.

A method of manufacturing a laminated dressing that includes providing a lower layer having a fiber material that directly contacts a patient's skin and a wound area, providing an upper layer that has a foam or foam-like material that absorbs exudate and moisture, and binding the fiber-based lower layer and the foam-based upper layer with a binder layer comprising a binder material, the binder layer including a series of perforations. The perforations in the binder layer are formed by removing material from the binder layer with a pattern coated adhesive sheet prior to binding the fiber-based lower layer and the foam-based upper layer.

A binder layer for a laminated wound dressing is brought into contact with a sheet coated with a pattern-coated adhesive sheet. As the binder layer is in contact with the pattern-coated adhesive sheet, a series of closed-loop cuts are made in the binder layer. The closed-loop cuts are made in such a way that the material enclosed by each closed loop is substantially physically separated from the remainder of the binder layer. Then the binder layer is moved away from the pattern-coated adhesive sheet, so that the binder layer and the pattern-coated adhesive sheet are no longer in contact. When the binder layer and the pattern-coated adhesive sheet are moved apart, the material enclosed in the closed-loop cutsi.e., the cut waste fragmentsare retained on the pattern-coated adhesive sheet, ensuring that the binder layer includes a series of cleared perforations.
