Patent attributes
An apparatus for procuring bodily fluid samples with reduced contamination includes a housing having a sequestration chamber, an inlet, and an outlet. A flow controller defines a portion of the sequestration chamber and can transition—in response to a suction force exerted by a fluid collection device fluidically coupled to the outlet—from a first state in which the sequestration chamber has a first volume to a second state in which the sequestration chamber has a second volume greater than the first volume, to draw an initial volume of bodily fluid into the sequestration chamber. An actuator is coupled to the housing and is in fluid communication with the inlet and the sequestration chamber in a first configuration, and is transitioned to a second configuration to sequester the sequestration chamber from the inlet, and allow a subsequent volume of bodily fluid to flow from the inlet to the outlet.
