摘要： A check valve assembly having a reduced net impact upon hemolysis, where the valve assembly has an elongated valve body including an inlet port, an outlet port, and an internal channel communicating between the ports, with each port disposed about and generally aligned with a central longitudinal axis of the body. The inlet port includes an umbrella-type check valve, and the internal channel is defined by three annular wall portions: a first annular wall portion aligned generally perpendicularly to the longitudinal axis to form a valve seat, a second annular wall potion that is generally concave, and a third annular wall portion that is generally convex, with the first, second and third annular wall portions forming an adjoining and essentially continuously curved, contiguous interior surface which smoothly redirects fluid flow toward the central longitudinal axis of the body and the outlet port.

摘要： A fluid check valve incorporating a temporary elastomeric functional barrier membrane, the check valve having a sealing member comprising a first elastomer and a barrier membrane comprising a second elastomer, different from the first elastomer, disposed directly upon the surface of the sealing member so as to form a continuous layer over at least a seal opening of the sealing member. The barrier membrane may include a photoinitiator and coagent which aids in the ultraviolet (UV) curing of the second elastomer after application upon the first. The barrier membrane may applied as a solution of monomers, photoinitiator, and optional coagent, the solvent evaporated, and the deposited solutes exposed to ultraviolet so as to form the barrier membrane material.
