Medical tapes include an optically transparent tape backing and an optically transparent adhesive layer, typically a pressure sensitive adhesive, disposed on the backing The tape is optically transparent and has a moisture vapor transmission rate (MVTR) of at least 250 g/m.sup.2 /24 hrs/37° C./100-10% RH using the inverted cup method. The tape remains optically transparent when over-taped, such that a multi-layer tape stack of at least 2 layers of tape are formed.

Medical adhesive articles include a layer of adhesive and a modified substrate layer where the layer has a plurality of cuts arrayed in a pattern that may be random or the pattern can be arrayed along at least one axis. The cuts are gaps, but the gaps are not visible to the naked eye when the adhesive article is in an unstressed state, and at least some of the cuts become gaps that are visible to the naked eye and form apertures when the adhesive article is in a stressed state. The adhesive articles can be used to adhere a medical device to skin.

A method for manufacturing a medical tape includes: applying a solution polymer serving as an elastic base member portion having an elastic function to an upper layer of a film forming base portion having an inelastic function to form a film of the solution polymer; laminating an adhesion portion having a function to apply and hold the elastic base member portion to a skin on an upper layer of the elastic base member portion, and laminating a release portion having a function to protect the adhesion portion on an upper layer of the adhesion portion; peeling and removing the film forming base portion from the elastic base member portion to obtain the elastic base member portion in a state where a residual shrink force generated by a forming shrinkage of the solution polymer is reduced and to obtain a three-layer structure consisting of the elastic base member portion.

An adhesive article that remains securely bonded to a substrate until a stimuli is applied. The article may be embodied as an adhesive tape, a bandage, or as other articles. The stimuli may be a change in temperature or application of a reduction that causes a structure within the article to break, creak, or otherwise disrupt to expose the adhesive to a solvent, such as via a difference in Coefficient of Thermal Expansion (CTE) or by exposing the article to a glass transition temperature.

A holder for securing a venous access device to a patient may include a flexible substrate having an upper surface, a lower surface, and an outer perimetal surface. An adhesive layer may overlay the lower surface of the flexible substrate. The adhesive layer may have an adhesive for adhering to skin of the patient. The holder may further include a hydrophilic matrix integrated into at least a portion of the adhesive layer, at least one solvent reservoir disposed on the upper surface of the flexible substrate, and a connector secured to the outer perimetal surface. The connector may have a first end for connection to a needle assembly and a second end for connection to an IV fluid line.

A bandage for the treatment of animal wounds and related method includes use of a flexible kinesiology tape, a pressure-sensitive adhesive and an absorbent pad disposed on an inner face of the kinesiology tape. The pressure-sensitive adhesive retains the absorbent pad on the tape while a residual portion is free to adhere in use to itself or a surface such as a skin surface surrounding the wound to retain the bandage in position.

A top band (1, 1′) for garments (2), in particular for medical compression stockings or bandages, comprising a flexible basic body (3, 3′) with an inside (4, 4′) facing the garment (2) and an outside (5, 5′), wherein the flexible basic body (3, 3′) comprises a fastening section (7, 7′) for the garment (2) on the inside (4, 4′) next to a coupling section (6, 6′), and wherein the fastening section (7, 7′) is formed by an edge-side recess (8, 8′) in the flexible basic body (3, 3′), so that the garment (2) can be fastened, offset from the coupling section (6, 6′) of the flexible basic body (3, 3′), in the recess (8, 8′).

A system for treating a tissue site includes a reduced-pressure source to apply reduced pressure, a manifold in fluid communication with the pressure source to provide reduced pressure to the tissue site, and a drape for adhering to the tissue site to cover the tissue site and the manifold. The drape includes an adhesive layer for sealing the drape to the tissue site to create a sealed space having the manifold therein, and a non-adhesive layer formed from a portion of the adhesive layer. A method for manufacturing a medical drape includes providing a sheet of adhesive material and treating a side of the sheet of adhesive material to form a non-adhesive layer and an adhesive layer. The method laminates a release liner adjacent the adhesive layer.

A wound dressing for a burn or open wound is formed of a foam material body with an open center area. The thickness of the foam body creates a zone for air circulation and prevents contact with the wound. This may have a mesh, gauze or other air permeable cover over the open center area.

An adhesive article that remains securely bonded to a substrate until a stimuli is applied. The article may be embodied as an adhesive tape, a bandage, or as other articles. The stimuli may be a change in temperature or application of a reduction that causes a structure within the article to break, creak, or otherwise disrupt to expose the adhesive to a solvent, such as via a difference in Coefficient of Thermal Expansion (CTE) or by exposing the article to a glass transition temperature.
