Abstract

A multi-chambered blood culture device for simultaneously conducting two blood culture tests on a single blood sample. An integrated unit including a syringe port with pin extensions is provided for receiving a blood sample simultaneously into two independent sample compartments. At least two culture chambers contain growth media, one culture chamber preferably containing an aerobic growth medium and another culture chamber preferably containing an anaerobic growth medium. The device is configured to isolate the sample vials and culture chambers from contaminants of the external environment. Downward pressure on the syringe port causes the pin extensions to breache the sample compartment walls and thereby releases the blood sample from one sample compartment into one culture chamber while simultaneously releasing the blood from the other sample compartment into the other culture chamber. In the preferred embodiment, outer walls of the device are constructed of transparent plastic so as to enable visual observance of microorganism growth in the respective culture chambers.
