Abstract
A syringe device has a hollow tubular body that receives a resilient sealing member rotatably connected to a hollow plunger. A vacuum pump is connected through a flexible tube to the hollow plunger to thereby withdraw blood using the vacuum created. Once in the syringe body, blood is automatically exposed to an anti-coagulant stored within the syringe body. The anti-coagulant is in flake form and premanufactured from a heparin solution which is allowed to evaporate on a non-stick surface.
