Problems solved by technology

[0013] Another disadvantage of this method and specific dressings is that the surface roughness of the silicone gel coat is highly dependent on the surface of the foam to be coated
Where a smooth silicone gel layer is required to wear next to the skin, this method cannot produce such a smooth silicone layer

Embodiment approach

[0088] According to one embodiment, the capsule holders are arranged in a rectangular pattern, with individual capsule holders being generally 5 mm apart (measured from the central axis of each capsule holder). The depth of each capsule support is generally 4-5mm, at least 0.5mm away from the surface layer. The pattern can be tailored to include more pocket receptacles in certain dressing areas than in other areas.

[0089] The density of the receptacle can be modified according to the desired fluid absorption properties of the dressing. For example, more pockets may be arranged at a higher density in the central portion of the absorbent core than near the border portions of the dressing. The number of pocket holders at any given area of ​​the absorbent core may depend on the sensing area where a greater amount of fluid is locally present, for example, at the central portion, to maximize fluid absorption while also limiting certain absorbent core areas, For example, in the b...

Abstract

A method for producing a wound dressing wherein a curable silicone mixture is extruded onto a generally planar molding surface. The silicone mixture defines a first surface adjacent the planar surface and a second surface opposite the first surface. The molding surface is heated at a curing temperature sufficient to cause the silicone mixture to cross-link. The silicone mixture is uniformly spread over the molding surface such that the silicone mixture has a generally uniform thickness and the second surface is substantially planar. The second surface of the silicone mixture is laminated to an absorbent material after the silicone mixture has started to cross-link and transform to a gel due to exposure to the heated molding surface.

Description

Background technique [0001] Historically, wounds have been treated with materials from a variety of different sources, ie, with some type of absorbent material to absorb wound fluid and tissue (commonly referred to as "exudate") from the wound site. In recent years, polymer-based wound care products are becoming more common for controlling wound site environmental factors such as water vapor, oxygen permeability, bacterial impermeability, and absorption of exudate. Such wound care products are specifically manufactured to meet specific requirements, including conformality to body parts, selective attachment to the wound bed, and adhesion to the skin surrounding the wound site. [0002] Recently, occlusive or moisturizing dressings are gaining acceptance in the management of wounds, especially decubitus ulcers and ulcers. Various types of structures are known in the art for use in or as wound dressings, generally comprising components to receive, absorb and retain exudates. T...
