Abstract
A plunger-less syringe and method of use are disclosed. The syringe includes an outer housing fixedly attached to an interior receptacle for receiving a quantity of blood. The syringe has a vent that allows air to escape from the receptacle as blood flows therein. The vent can include a filter for use in preventing blood from exiting the interior receptacle. A vent cap is provided having a recess for mating with a syringe having a plunger, wherein blood flow into the receptacle can be controlled. A plurality of the plunger-less syringes can be packaged in a container, wherein the blood pathway of the syringes is sterilized and without having any exterior sterile packaging.
