Abstract: The present invention describes a pressure-sensitive hydrophilic laminate composite comprising contiguous layers of a tacky pressure sensitive hydrophilic polymer blend, and a non-tacky hydrophilic polymer blend. Numerous variations in individual layer formulations allow for a multitude of hydrophilic blend laminate composite structures, which are readily utilizable as wound dressings, and/or transdermal and topical delivery systems incorporating a wide range of bioactive agents. The hydrophilic laminate composite structurese are characterized by ease of application, adhesiveness to skin, high tensile strength, mechanical integrity, transparency, fluid absorbency, and highly effective bacterial barrier properties, and permeability to water vapor, oxygen and drugs and/or bioactive agents. In the preferred embodiments, they are further characterized in their ability to inhibit severe maceration of the wound as well as underlying tissue destruction upon removal.

The barriers provide envelopes to prevent that fluid from leaking out the sides of the absorbent pad, onto a wearer thereof.

Abstract: A point-of-use membrane filtration system and method for water or other liquids including an automatic control system for purge, rinse-up, sanitization, or combinations thereof. The system may be used for microfiltration, ultrafiltration or hyperfiltration (reverse osmosis) depending on the membrane pore size of the filtration cartridge employed in the system. A reject valve at the bottom of the filter cartridge is automatically opened when filtered product is drawn, thus to direct some water and any waste to drain. The control system is programmed to accomplish purge, rinse-up and sanitization procedures at predetermined intervals with predetermined combinations of procedures.
