Systems and methods for parenterally procuring bodily-fluid samples with reduced contamination

摘要

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 Prior to withdrawing bodily fluid into the one or more sample vessels for incubation, an initial volume of withdrawn bodily fluid is placed in one or more pre-sample reservoirs and is not used for the incubation in culture media.

主权项

1. A method of establishing a fluid flow path between a patient and a fluid container, the method comprising:
establishing fluid communication between the patient and a lumen-containing device; withdrawing a first volume of a bodily-fluid from the patient, the first volume of bodily-fluid being greater than the volume of the lumen-containing device and less than 5 ml; transferring the first volume of bodily-fluid to a fluid reservoir via the lumen-containing device; fluidically isolating the lumen-containing device from the fluid reservoir to sequester the first volume of bodily-fluid in the fluid reservoir; and establishing fluid communication between the patient and the fluid container with the lumen-containing device, whereby sequestering the first volume of bodily-fluid in the fluid reservoir sequesters microbes present in the first volume of bodily-fluid from the fluid flow path, thereby reducing contamination in the fluid flow path and any subsequent volumes of bodily-fluid withdrawn from the patient.
