Abstract
Disclosed is an apertured hydrogel that is used in connection with an insertion device to provide comfort at the site of entry into the skin. In one embodiment, the hydrogel contains antimicrobial properties to help inhibit microbial growth at the site of insertion of the device into the skin. In the invention the apertured hydrogel is provided with a medical dressing and comprises a hydrogel having an upper surface and a lower surface, a film covering the upper surface of the hydrogel, a base sheet releasably covering to the lower surface of the hydrogel, an aperture in the film and hydrogel from the upper surface to the lower surface of the hydrogel, wherein the base sheet extends beyond the hydrogel to form a tab.
Claims7
A medical dressing comprising:
- a hydrogel having an upper surface and a lower surface;
- a first film covering the upper surface of the hydrogel;
- an aperture in the first film and hydrogel from the upper surface to the lower surface of the hydrogel, wherein the aperture is a slit into the hydrogel from a perimeter of the hydrogel;
- a base sheet releasably covering the lower surface of the hydrogel, wherein a first portion of the base sheet extends beyond the perimeter of the hydrogel and is folded back at a fold onto a second portion of the base sheet covering the lower surface of the hydrogel such that the base sheet extends beyond the perimeter of the hydrogel opposite the fold to form a first tab;
- and
- a continuous cut which passes through the fold of the base sheet but does not extend to the perimeter of the base sheet, wherein the continuous cut coincides with the aperture in the first film and hydrogel;
- wherein the first portion of the base sheet comprises second and third tabs that extend beyond the perimeter of the hydrogel in opposite directions.
