Rapid, high-volume, intradermal infusion with minimal pain, is achived by applying an array of 10 to 30 hollow microneedles having a length of greater than 100 um to less than 1 mm into the skin of a patient, with a microneedle spacing of no less than 1.5 mm on average between adjacent microneedles, and pumping greater than 200 uL of fluid through the hollow microneedles at a rate of greater than 20 uL/min.
摘要:
A sample acquisition device includes a body comprising a plurality of sample acquisition regions defined by at least a first wall and a second wall oriented nonparallel to the first wall. In some embodiments, the body defines a plurality of apertures that define a plurality of sample acquisition regions. In other embodiments, the walls extend from the body, and the sample acquisition regions are defined between the walls. The sample acquisition regions may be configured in some embodiments such that a user may acquire a sample by rotating the body in a first direction relative to a sample source and may release the sample by rotating the body in a second direction that is substantially opposite to the first direction. When rotated in the first direction, at least one of the first or second walls defines a surface that is inclined into a sample acquisition region.
摘要:
Medical articles including an absorbent layer, a backing layer and an optional liquid permeable facing layer are disclosed. The construction of the medical article is such that volumetric expansion of the absorbent layer is allowed in directions parallel to the surface of the backing layer as the absorbent layer absorbs moisture. The medical article may include a debonding agent located between the absorbent layer and the backing layer. The absorbent layer is operably attached to the backing layer. When the absorbent layer absorbs moisture, e.g., wound exudate, at least a portion of the absorbent layer detaches from the backing layer such that the absorbent layer can expand and move relative to the backing. The debonding agent facilitates this change from attachment to detachment of the absorbent layer to the backing. The medical articles of the present invention may also be constructed such that a portion of the front surface of the backing layer located directly opposite the absorbent layer is free of adhesive. The adhesive free area or areas may be provided in place of a physical debonding agent or in addition to a physical debonding agent.

摘要:
An adhesive hydrogel dressing as well as methods of applying the dressing to a patient. The dressing generally comprises an adhesive hydrogel pad, a backing layer, and an adhesive layer on the backing layer facing the hydrogel pad. The adhesive layer and backing layer form a perimeter around the hydrogel pad and hold the hydrogel pad in place on an application surface. A release element is in contact with at least a portion of the edge of the hydrogel pad proximate the area that the hydrogel pad and release liner separate during liner removal.

A polymer composition that includes a hydrophilic polymer, an optional secondary organic polymer, and a bioactive agent distributed therein, wherein the bioactive agent is selected from the group consisting of a silver compound, a copper compound, a zinc compound, and combinations thereof.
摘要:
An absorbent dressing comprising a hydrophilic gel absorbent layer having a patterned surface on at least one major surface thereof is provided. The patterned surface allows greater surface area for absorption of wound exudate when oriented toward the wound surface, while reducing the absorbent surface area in direct or indirect contact with the wound.
