Abstract
A syringe for sampling bodily fluids, such as blood and the like, from a patient, comprises a first sleeve member and a second sleeve member disposed for relative shifting. The first sleeve member includes a first receiving chamber, and the second sleeve member includes a second receiving chamber. A needle mount is disposed on the first sleeve member for holding a needle in operative connection with the first receiving chamber so that bodily fluids can pass from the needle into the first receiving chamber. A filter is disposed in at least one of the first and the second sleeve members for permitting gas flow but prohibiting bodily fluid flow therethrough. The first receiving chamber communicates with the second receiving chamber through the filter so that relative shifting of the sleeve members causes gas within the first receiving chamber to flow through the filter into the second receiving chamber, thereby causing bodily fluid to flow into a first receiving chamber.
