Systems and methods for parenterally procuring bodily-fluid samples with reduced contamination
The present invention is directed to the parenteral procurement of bodily-fluid samples. The present invention is also directed to systems and methods for parenterally procuring bodily-fluid samples with reduced contamination from dermally-residing microbes. In some embodiments, a bodily-fluid withdrawing system is used to withdraw bodily fluid from a patient for incubation in culture media in one or more sample vessels. Prior to withdrawing bodily fluid into the one or more sample vessels for incubation, an initial volume of withdrawn bodily fluid is placed in one or more pre-sample reservoirs and is not used for the incubation in culture media.

establishing fluid communication between the port and the first reservoir via the first flow path;
receiving from the patient a first volume of bodily-fluid into the first reservoir;
as a result of filling the first reservoir, automatically sequestering the first volume of bodily-fluid in the first reservoir;
establishing fluid communication between the port and the second reservoir via the second flow path; and
