A method and apparatus for automatically splicing two continuous three-layer tapes, wherein a longitudinally movable continuous wound tape is transversely cut so as to form individual wound pads which are applied in longitudinally spaced positions on adhesive surfaces of continuous carrier foils, and wherein a splicing element is cut from the continuous wound tape and is applied on tail and head portions of two continuous carrier foils.

The disclosure provides dermal patches capable of delivering one or more pharmaceutical agents that reduce pain, where the patch can include one or more of a film, adhesive, emulsifier, tackifier, and hydrogel.

Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus can include a wound dressing with a spacer layer separated from the absorbent layer by intermediate layers or drapes. The wound dressing can include a first portion comprising a wound contact or tissue contact layer, a first spacer layer, and a first backing layer comprising a first aperture. The spacer layer can be positioned between the contact layer and the first backing layer. The dressing can have a second portion comprising an intermediate drape with a second aperture, an absorbent layer, and a second backing layer. The absorbent layer is positioned between the intermediate drape and the second backing layer. The first aperture and the second aperture are configured to be sealed and allow fluid communication between the first portion and the second portion of the wound dressing.

Dressings for treating a tissue site with negative pressure are disclosed, which may include a dressing having at least three layers assembled in a stacked relationship. In one example embodiment, a first film may comprise a non-porous material and a plurality of fluid restrictions. A first manifold layer may be adjacent to the first film and may comprise a second film of a transparent material having blisters and a manifold area. The first manifold layer may further comprise apertures configured to allow fluid transfer through the second film. A second manifold layer may be adjacent to the first manifold layer and may comprise foam having a contact area that is less than the manifold area of the first manifold layer.

A dressing for treating a tissue site with negative pressure includes a manifold having a first surface and a second surface opposite the first surface. The dressing also includes a first layer adjacent to the first surface and a second layer adjacent to the second surface. The first layer and the second layer each include a polymer film. The dressing also includes a plurality of fluid restrictions in the polymer film adjacent to at least the first surface, and a plurality of bonds between the first layer and the second layer. The plurality of bonds defines separable sections of the manifold.

A dressing for application to human or animal skin and/or to medical devices, comprising a fixing web provided with an adhesive on a fixing surface, covering means removably attached to the fixing surface, and support means connected to the covering means and removably attached to an outer surface of the fixing web facing away from the fixing surface, wherein the outer surface has an exposed shaping surface which is at least partially surrounded by the support means.

A three-dimensional electrospun biomedical patch includes a first polymeric scaffold having a first structure of deposited electrospun fibers extending in a plurality of directions in three dimensions to facilitate cellular migration for a first period of time upon application of the biomedical patch to a tissue, wherein the first period of time is less than twelve months, and a second polymeric scaffold having a second structure of deposited electrospun fibers. The second structure of deposited electrospun fibers includes the plurality of deposited electrospun fibers configured to provide structural reinforcement for a second period of time upon application of the three-dimensional electrospun biomedical patch to the tissue wherein the second period of time is less than twelve months. The three-dimensional electrospun biomedical patch is sufficiently pliable and resistant to tearing to enable movement of the three-dimensional electrospun biomedical patch with the tissue.

Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising a number of viewing portals that facilitate observation of wound tissue or healthy skin underlying the wound dressing. Some embodiments of the viewing portals are provided by forming through holes in internal dressing layers including absorbent material and transmission material, optionally by providing a plug material within the through holes, and by providing translucent or transparent cover layer and tissue contact layer materials.

Provided are a stretchable non-woven fabric including crimped fibers, satisfying the following formula: (σ.sub.65−σ.sub.55)/(σ.sub.30−σ.sub.20)≥2.5, when a stress σ (N/50 mm) at a strain ε of 20%, 30%, 55% and 65% in a stress-strain curve by a tensile test for at least one direction in a plane direction, is referred to as σ.sub.20, σ.sub.30, σ.sub.55 and σ.sub.65, respectively, and a bandage including the non-woven fabric. The non-woven fabric and the bandage lead small deterioration in stretching performance when used repeatedly, and can be excellent in repetition durability.
