ABSTRACT:
A blood sampling device having a valve assembly which prevents the backflow of blood into a patient, and which is especially suitable for multiple sample collection. The valve assembly includes a mounting structure for a valve member, a chamber to house the valve, and a valve which has a resilient skirt allowing fluid flow only in one direction. The valve member is prevented from cocking by a protruding portion which fits within a recess of the mounting structure and by valve positioning members within the valve chamber.
