摘要： An elastomeric gland is provided for a luer activating device (LAD). and comprises a unique lubricant and/or wetting agent and/or anti-clotting agent incorporated into the elastomer gland during raw material formulation, calendar blending/molding/curing to deliver the surface lubricity and/or wettability and/or avoid slit plane re-knitting and/or gland induced valve stick down of such devices Functional additive chemistries are selected in terms of generated functional performance level, thermal stability against processing, molecular migratability, molecular weight and elastomer substrate of interest. These additives could include lubricants like chemically modified silicone oils and/or wetting agents like silicone-based surfactant. Elastomer gland with wetting agent would ease fluid path priming and minimize micro air bubble adherence to gland surface. Additives may also include anti-clotting agents intended to reduce potential for clot formation within the fluid path and interstitial space of the valve during blood sampling and infusion.

摘要： The present invention pertains, in a preferred embodiment, to a fluid-pervious web comprising a first or wearer-contacting surface and a second or garment-facing surface. The web is particularly well suited for use as a topsheet on a disposable absorbent article. The first and second surfaces are separated from one another by an intermediate portion. The first surface of the web provides a structure which exhibits a surface energy less than the surface energy of the intermediate portion. In a preferred embodiment, the web exhibits a plurality of regions of comparatively low surface energy which define surface energy gradients where they interface with higher surface energy web surfaces. More particularly, the present invention pertains to a fluid-pervious web having a plurality of small-scale surface energy gradients which are oriented and located so as to effectively transport fluid away from the first or wearer-contacting surface. The web essentially retains its visual, tactile, and physical properties of the substrate material while achieving the desired surface energy properties. Fluid transport webs according to the present invention preferably include discontinuous, spaced regions defining small scale surface energy gradients on the first surface to aid in small scale fluid movement toward apertures or capillary entrances for transport away from the first surface. Such webs also preferably include small scale surface energy gradients normal to the first surface within a capillary structure to aid in moving fluid away from the first surface and into the capillaries for capillary fluid transport. Web materials suitable for use in the present invention include apertured formed films, apertured and non-apertured nonwoven materials, composite structures, and the like.

摘要： This invention relates to a process for forming a single-layer, durably wettable polymeric web having a plurality of apertures. This process comprises melting a mixture of at least one thermoplastic polymer and at least one migratable surfactant and extruding the mixture to form a single-layer, substantially continuous polymeric film. The film is then apertured using high pressure fluid flows. Aperture formation is conducted when the single-layer polymeric film has a contact angle of at least about 30.degree., to minimize wash-off of the surfactant impregnated in the polymer web. The invention also relates to durably-wettable apertured webs.
