1. A bodily fluid sequestration device, comprising:

  • a housing having a first port configured to be fluidically coupled to a patient and a second port configured to be fluidically coupled to an external fluid reservoir;

    an internal fluid reservoir disposed in the housing and configured to receive and sequester an initial volume of bodily fluid withdrawn from the patient;

    a flow control mechanism disposed in the housing and defining a first lumen and a second lumen, the first lumen at least partially defining the internal fluid reservoir and configured to fluidically couple the first port to the internal fluid reservoir, and the second lumen configured to fluidically couple the first port to the second port; and

    a valve disposed in the first lumen and configured to form a substantially fluid tight seal with the walls defining the first lumen in a closed configuration, and configured to allow the flow of bodily fluid in a single direction in an open configuration,the bodily fluid sequestration device configured to allow the initial volume of bodily fluid to flow from the first port to the internal fluid reservoir, and to establish a fluid flow path between the first port and the second port once the initial volume of bodily fluid is sequestered in the internal fluid reservoir and the valve is in the closed configuration.
