Abstract:
1. A method of obtaining a bodily-fluid sample from a patient using a parenteral sampling device, the method comprising: establishing fluid communication between the patient and an inlet port of the parenteral sampling device; disposing a flow control mechanism in a first configuration, the first configuration operable to allow bodily-fluid to flow from the patient, through the inlet port, and into a fluid reservoir; moving an actuator a first distance to form a negative pressure in the fluid reservoir, the actuator including a seal member that defines a portion of the fluid reservoir such that the moving of the actuator the first distance moves the seal member from a first position toward a second position to form the negative pressure in the fluid reservoir; receiving a first volume of bodily-fluid into the fluid reservoir while the flow control mechanism is in the first configuration; moving the actuator a second distance, after the first volume of bodily-fluid has been received into the fluid reservoir, to move the flow control mechanism from the first configuration to a second configuration, the second configuration operable to (1) fluidically isolate the first volume of bodily-fluid in the fluid reservoir, and (2) allow bodily-fluid to flow from the patient to a sample reservoir.
