Fluid diversion mechanism for bodily-fluid sampling
First Claim
1. A device for parenterally-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;
a fluid reservoir disposed within the housing, the fluid reservoir configured to be selectively placed in fluid communication with the inlet port; and
a flow control mechanism disposed in the inner volume and configured to be transitioned between a first configuration and a second configuration, the flow control mechanism including a first seal member and a second seal member collectively defining at least a portion of the fluid reservoir, the first seal member configured to move relative to the second seal member from a first position to a second position in response to a force to place the flow control mechanism in the first configuration in which the inlet port is in fluid communication with the fluid reservoir,the first seal member and the second seal member collectively configured to move relative to the housing in response to the force after the first seal member is placed in the second position to transition the flow control mechanism to the second configuration in which the inlet port is in fluid communication with an outlet port, the second seal member fluidically isolating the fluid reservoir from the inlet port when the flow control mechanism is in the second configuration.

Abstract
An apparatus includes a housing, a flow control mechanism, and an actuator. At least a portion of the flow control mechanism is movably disposed within the housing. The apparatus further includes an inlet port and an outlet port, and defines a fluid reservoir. The outlet port is fluidically coupled to a second fluid reservoir and is fluidically isolated from the first fluid reservoir. The actuator is configured to move the flow control mechanism between a first configuration, in which the inlet port is placed in fluid communication with the fluid reservoir such that the fluid reservoir receives a first flow of bodily-fluid, and a second configuration, in which the inlet port is placed in fluid communication with the outlet port.

-
a housing including a proximal end portion and a distal end portion and defining an inner volume therebetween, the housing having an inlet port; a fluid reservoir disposed within the housing, the fluid reservoir configured to be selectively placed in fluid communication with the inlet port; and a flow control mechanism disposed in the inner volume and configured to be transitioned from a first configuration to a second configuration, the flow control mechanism including a first seal member and a second seal member, a volume defined between the first seal member and the second seal member forming at least a portion of the fluid reservoir, the flow control mechanism further including a first control member and a second control member, the first control member configured to move a first distance in response to a force to place the flow control mechanism in the first configuration in which the inlet port is in fluid communication with the fluid reservoir, the first seal member configured to move relative to the second seal member as the first control member is moved the first distance such that the volume defined between the first seal member and the second seal member is increased from a first volume to a second volume, the first control member configured to move a second distance after moving the first distance in response to the force to place the flow control mechanism in the second configuration in which the inlet port is placed in fluid communication with an outlet port, the second seal member configured to move with the first control member as the first control member is moved the second distance to fluidically isolate the fluid reservoir from the inlet port. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A device for parenterally-procuring bodily-fluid samples from a patient, the device comprising:
-
a housing including a proximal end portion and a distal end portion, the housing having an inner surface defining an inner volume, the housing including an inlet port and an outlet port in fluid communication with the inner volume; a first control member disposed in the inner volume and operably coupled to a first seal member, the first seal member forming a substantially fluid tight seal with the inner surface of the housing; a second control member disposed in the inner volume and operably coupled to a second seal member, the second seal member forming a substantially fluid tight seal with the inner surface of the housing, a portion of the inner volume defined between the first seal member and the second seal member defining at least a portion of a fluid reservoir; and an actuator operably coupled to the housing, the actuator configured to move the first control member within the housing from a first position to a second position in response to a actuation force, the first control member being placed in contact with the second control member when in the second position, the inlet port being in fluid communication with the fluid reservoir as the first control member is moved from the first position to the second position, the actuator configured to move the first control member within the housing from the second position to a third position in response to the actuation force, the second control member moving with the first control member as the first control member is moved from the second position to the third position, the second seal member fluidically isolating the fluid reservoir from the inlet port and placing the inlet port in fluid communication with the outlet port when the first control member is in the third position. - View Dependent Claims (15, 16, 17, 18, 19, 20)
