Fluid diversion mechanism for bodily-fluid sampling
First Claim
1. A device for procuring bodily-fluid samples from a patient, the device comprising:
- a housing including a proximal end portion and a distal end portion and defining an inner volume therebetween, the housing having an inlet port configured to be fluidically coupled to the patient, and an outlet port configured to be fluidically coupled to a sample reservoir;
a fluid reservoir disposed in the inner volume and configured to receive and isolate a first volume of bodily-fluid withdrawn from the patient;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 flow control mechanism configured for rotational movement from a first configuration, in which the inlet port is placed in fluid communication with the fluid reservoir such that bodily-fluid can flow from the inlet port, through the first lumen and to the fluid reservoir, to a second configuration, in which the inlet port is placed in fluid communication with the outlet port such that the bodily-fluid can flow from the inlet, through the second lumen and to the outlet port; and
an actuator operably coupled to the flow control mechanism and configured to create a negative pressure in the fluid reservoir when actuated by a user, the actuator further configured to rotate the flow control mechanism from the first configuration to the second configuration after the first volume of bodily-fluid is received in the fluid reservoir from the patient.

Abstract
An apparatus includes a housing, a fluid reservoir, a flow control mechanism, and an actuator. The housing defines an inner volume and has an inlet port that can be fluidically coupled to a patient and an outlet port. The fluid reservoir is disposed in the inner volume to receive and isolate a first volume of a bodily-fluid. The flow control mechanism is rotatable in the housing from a first configuration, in which a first lumen places the inlet port is in fluid communication with the fluid reservoir, and a second configuration, in which a second lumen places the inlet port in fluid communication with the outlet port. The actuator is configured to create a negative pressure in the fluid reservoir and is configured to rotate the flow control mechanism from the first configuration to the second configuration after the first volume of bodily-fluid is received in the fluid reservoir.
