Abstract
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.
