Abstract
A multiple sample needle assembly useful in collecting fluid samples from a source includes a housing with a chamber therein. A first cannula, in fluid communication with the chamber, is provided for insertion into a fluid source. A second cannula is movably positioned in the housing and communicates with the chamber. A flow mechanism inside the chamber prevents fluid from flowing from the chamber into the second cannula. This flow mechanism is operatively responsive to inward movement of the second cannula to allow fluid to flow from the chamber into the second cannula for collection therefrom.
