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 a syringe port and a piston assembly for receiving a specimen syringe and for enabling a predetermined quantity of blood to be injected into two sample cups. Isolated media compartments contain growth media, one preferably containing an aerobic growth medium and another preferably containing an anaerobic growth medium. Once the blood specimen is fully injected into the sample cups, the sample cups are released into the media compartments, thereby enabling the blood specimens to mix with the respective growth media for testing. Further, means may also be provided to lock the syringe into the integral device in order to facilitate efficient disposal upon completion of testing. Additionally, 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.
