ABSTRACT:
A syringe device for use with drawing blood or other fluids directly into a sealed sterile environment for culturing which includes a hollow housing defining the syringe chamber therein, further including a movable piston adapted for longitudinal sliding movement within the syringe chamber such that when the piston is withdrawn a partial vacuum is created within the chamber and blood is drawn therein, further including at least one culture cavity defined in the walls of the housing and opening into the chamber within the housing and being adapted to contain therein particularly chosen culturing media in accordance with the particular tests being conducted, further including a sealing means about the periphery of the movable piston such that after the fluid has been drawn into contact with the culturing cavities the piston may be moved back upwardly to seal the culturing media with respect to the outside environment and with respect to the chamber within the syringe to allow for a sterile culturing of the fluid, further including a hollow nipple means adapted to receive a needle detachably affixed thereto to facilitate drawing of fluids into the chamber of the syringe, also including a capping means which is detachably affixable to the nipple means to selectively seal hermetically the chamber from the external environment.
