摘要：
An apparatus includes an inlet configured to be placed in fluid communication with a bodily fluid source and an outlet configured to be placed in fluid communication with a fluid collection device. A sequestration portion can be configured to receive an initial volume of bodily fluid. A flow controller disposed in the sequestration portion can be configured to transition from a first state to a second state in response to contact with the initial volume of bodily fluid. As the flow controller transitions, a negative pressure differential can be defined that is operable to draw the initial volume of bodily fluid into the sequestration portion. When the flow controller is in the second state, the negative pressure differential can be substantially equalized such that (1) the sequestration portion sequesters the initial volume and (2) a subsequent volume of bodily fluid can be transferred from the inlet to the outlet.
