Abstract
A multi-chambered blood culture device for simultaneously conducting two blood culture tests on a single blood sample. An integrated unit is provided with rotating blood inlet valve assembly for receiving a blood sample simultaneously into two independent sample vials. Independent 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. By rotating the blood inlet valve assembly, blood is simultaneously released from one sample vial into one culture chamber and from the other sample vial into the other culture chamber. Outer walls of the device are preferably constructed of a transparent plastic material so as to enable visual observance of microorganism growth in the respective culture chambers.
