An adhesive device used as a wound dressing, ingredient delivery device or IV hold-down in which inadvertent edge release of these devices along the periphery of the polymeric film layer is minimized when the handling layer, which is adhered to the polymeric film layer, is removed after application of the polymeric film layer to the patient.

The present invention relates to a medical dressing and a manufacturing method, and to a medical dressing and a manufacturing method therefor, the medical dressing comprising: a lower support film; a release film; and an adhesive sheet part (110) for application, which is placed on the release film (200) and is attached to the skin, wherein the release film (200) consists of a release film part (210) for fixing and a separable release film part (220) to be separated therefrom by a cutting line (211) formed on the release film part (210) for fixing, so that a predetermined region of the separable release film part is positioned to overlap with the bottom surface of the adhesive sheet part (110), thereby allowing, during separation of the separable release film part (220) from the release film part (210) for fixing, separation together with the adhesive sheet part (110) for application, and the area of the separable release film part (220), which overlaps with the bottom surface of the adhesive sheet part (110), is relatively smaller than the area of the separable release film part, which does not overlap with the adhesive sheet part (110).

The securement device eliminates the drawbacks of prior venous cannulas securement method by providing various plates, substrates and adhesive layers in the securement device which secures the article firmly onto the underlying substrate arresting movement in all axis that does not need any additional form of securement.

A medical dressing comprising a backing layer and a self-supporting substrate. The backing layers form a perimeter around the self-supporting substrate and holds the self-supporting substrate in place on a wound. The medical dressing forms a sealed environment surrounding the wound such that a negative pressure can be maintained in the sealed environment through the valve.

Provided is a microneedle patch which is easily to be applied on a skin surface. One or more holes are provided inside a protective sheet of the microneedle patch, and one or more cutting lines running from an outer edge of the protective sheet toward the holes are also provided. The cutting lines may be symmetrically arranged on both sides of the hole. Providing an incision on the outer edge of the cutting lines of the protective release sheet facilitates cutting along the cutting lines. In the use of the microneedle patch, both sides of the cutting line of the protective release sheet are held and torn so as to bring out a microneedle array adhesive sheet and apply it on a skin. Then the microneedle array surface is slightly compressed, thereby the microneedle is inserted into the stratum corneum.

Methods of handling adhesive laminate patches. A first article, passed over a first supporting structure, includes disconnected adhesive laminate patches adhered to a first web, each patch being aligned over and adhered to a tab. A second web can be passed over a second supporting structure that is separated from the first supporting structure by a gap. The first article can be passed over the first supporting structure to lift a leading portion of a first tab and a first patch off of the first web together, such that the first tab facilitates transfer of the first patch across the gap. The first patch can then be adhered to the second web; and the second web can be advanced to transfer the first patch, and first tab, onto the second web to form a second article comprising patches aligned over tabs on the second web.

A medical dressing comprising a backing layer and a self-supporting substrate. The backing layers form a perimeter around the self supporting substrate and holds the self supporting substrate in place on a wound. The self supporting substrate comprises a valve. The adhesive article forms a sealed environment between the medical article and the surface surrounding the wound such that a negative pressure can be maintained in the sealed environment through the valve.

An adhesive patch assembly and method for making same. The assembly can include an adhesive patch and a release liner. The patch can include a backing and a skin-contact adhesive. The release liner can further include a first portion and a second portion separated by a hinge. The first portion can be positioned to overlay the backing of the patch when the release liner is folded upon the hinge, and the second portion can be positioned to underlie the skin-contact adhesive of the patch. The method can include positioning the patch on the release liner, such that patch is located on one of the first portion and the second portion of the release liner; and folding the release liner about to locate the patch between the first portion and the second portion of the release liner.
