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;
a fluid reservoir disposed in the inner volume and configured to receive and isolate a first volume of bodily-fluid withdrawn from the patient;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 at least partially disposed in the housing and configured to be placed in fluid communication with a patient, the flow control mechanism defining a first lumen and a second lumen, the flow control mechanism configured for movement from a first configuration, in which the first lumen places the fluid reservoir in fluid communication with the patient, to a second configuration, in which the second lumen places a sample reservoir in fluid communication with the patient; and
an actuator operably coupled to the flow control mechanism and configured to be moved a first distance to create a negative pressure in the fluid reservoir and a second distance to transition 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.

8. 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; an actuator movably disposed, at least in part, in the housing, the actuator including a seal member and a fluid reservoir defined at least in part by the seal member, the actuator configured to be moved relative to the housing between a first position, in which the fluid reservoir has a first volume, and a second position, in which the fluid reservoir has a second volume greater than the first volume, when actuated by a user, the increase in the volume of the fluid reservoir resulting in a negative pressure within the fluid reservoir; a diverter at least partially disposed in the housing, the diverter having an inlet port configured to be fluidically coupled to the patient, a first outlet port fluidically coupled to the fluid reservoir, and a second outlet port configured to be fluidically coupled to a sample reservoir, the diverter configured to move when the actuator is moved from the first position to the second position; and a flow control mechanism at least partially disposed in the diverter and defining a first lumen and a second lumen, the flow control mechanism configured to be disposed in a first configuration, in which the first lumen places the inlet port in fluid communication with the first outlet port, as the actuator moves from the first position toward the second position, the flow control mechanism configured to be transitioned to a second configuration, in which the second lumen places the inlet port in fluid communication with the second outlet port, after the actuator is placed in the second position. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. 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; an actuator movably disposed, at least in part, in the housing, the actuator including a seal member and a fluid reservoir defined at least in part by the seal member, the actuator configured to be moved relative to the housing between a first position, in which the fluid reservoir has a first volume, and a second position, in which the fluid reservoir has a second volume greater than the first volume, the increase in the volume of the fluid reservoir resulting in a negative pressure within the fluid reservoir; and a flow control mechanism at least partially disposed in the housing and configured to be placed in fluid communication with a patient and with a sample reservoir, the flow control mechanism defining a first lumen and a second lumen, the flow control mechanism operably coupled to the actuator and configured to be transitioned between a first configuration, in which the first lumen places the fluid reservoir in fluid communication with the patient, and a second configuration, in which the second lumen places the sample reservoir in fluid communication with the patient, as the actuator is moved between the first position and the second position. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
