摘要： An apparatus includes a cannula assembly, a housing, a fluid reservoir, a flow control mechanism, and an actuator. The housing includes an inlet port removably coupled to the cannula assembly and defines an inner volume. The fluid reservoir is fluidically coupled to the housing and configured to receive and isolate a volume of bodily fluid from a patient. The flow control mechanism is at least partially disposed in the inner volume. The actuator is operably coupled to the flow control mechanism and is configured to move the flow control mechanism between a first configuration, in which bodily fluid can flow, via a fluid flow path defined by the flow control mechanism, from the cannula assembly, through the inlet port and into the fluid reservoir, to a second configuration, in which the fluid reservoir is fluidically isolated from the cannula assembly.

摘要： A fluid transfer device for parenterally transferring fluid to and/or from a patient includes a housing, a needle, and an occlusion mechanism. The housing defines a fluid flow path and is couplable to a fluid reservoir. The needle has a distal end portion that is configured to be inserted into the patient and a proximal end portion that is configured to be fluidically coupled to the fluid flow path of the housing, and defines a lumen therebetween. The occlusion mechanism selectively controls a fluid flow between the needle and the fluid flow path. The occlusion mechanism includes an occlusion member that is movable between a first configuration where the lumen of the needle is obstructed during insertion into the patient and a second configuration where the lumen of the needle is unobstructed after the needle has been inserted into the patient allowing fluid transfer to or from the patient.

摘要： A fluid control device includes an inlet configured to be placed directly or indirectly in fluid communication with a bodily fluid source and an outlet configured to be placed in fluid communication with a fluid collection device. The fluid control device has a first state in which a negative pressure differential produced from an external source such as the fluid collection device is applied to the fluid control device to draw an initial volume of bodily fluid from the bodily fluid source, through the inlet, and into a sequestration portion of the fluid control device. The fluid control device has a second state in which (1) the sequestration portion sequesters the initial volume, and (2) the negative pressure differential draws a subsequent volume of bodily fluid, being substantially free of contaminants, from the bodily fluid source, through the fluid control device, and into the fluid collection device.

摘要： An apparatus includes a housing that defines a fluid reservoir and includes a port that is in fluid communication with the fluid reservoir. An inlet adapter is removably coupleable to the housing. A user can engage an actuator to move a plunger from a first position in which the fluid reservoir has a first volume, to a second position in which the fluid reservoir has a second volume greater than the first volume, which draws bodily fluid into the fluid reservoir via the inlet adapter. The actuator modulates a plunger rate of motion below a threshold as the plunger is moved. When a predetermined volume of bodily fluid is transferred into the fluid reservoir, a volume indicator transitions from a first state to a second state and the inlet adapter can then be removed to transfer the predetermined volume into a sample bottle external to the housing via the port.

摘要： A system includes a fluid transfer device and a lateral flow assay device. The fluid transfer device has an inlet fluidically coupleable to a bodily fluid source, an outlet fluidically coupleable to a sample reservoir, and a sequestration chamber configured to receive an initial volume of bodily fluid. The fluid transfer device can be transitioned between (1) a first state with the sequestration chamber in fluid communication with the inlet to receive the initial volume, (2) a second state with the outlet in fluid communication with the inlet to receive a subsequent flow of bodily fluid, and (3) a third state with the lateral flow assay device in fluid communication with the sequestration chamber to receive a portion of the initial volume of bodily fluid. The lateral flow assay device configured to provide an indication associated with a presence of a target analyte in the bodily fluid.

摘要： An apparatus includes a housing, defining an inner volume, and an actuator mechanism movably disposed therein. The actuator mechanism is configured to be transitioned from a first configuration to a second configuration to define a pre-sample reservoir fluidically couplable to receive a pre-sample volume of bodily-fluid via an inlet port of the housing. The actuator mechanism is movable from a first position to a second position within the housing after the pre-sample reservoir receives the pre-sample volume such that the housing and the actuator mechanism collectively define a sample reservoir to receive a sample volume of bodily-fluid via the inlet port. The outlet port is in fluid communication with the sample reservoir and is configured to be fluidically coupled to an external fluid reservoir after the sample volume is disposed in the sample reservoir to transfer at least a portion of the sample volume into the external fluid reservoir.

摘要： A fluid control device 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, which can produce a negative pressure differential between the outlet and the inlet. A sequestration portion is in fluid communication with the inlet and includes a first flow controller configured to transition from a first state to a second state to place the sequestration portion in fluid communication with the outlet when the negative pressure differential has a first magnitude. A sampling portion is in fluid communication with an outlet and includes a second flow controller configured to transition from a first state to a second state to place the sampling portion in fluid communication with the inlet when the negative pressure differential has a second magnitude greater than the first magnitude.

摘要： A syringe-based device includes a housing, a pre-sample reservoir, and an actuator. The housing defines an inner volume between a substantially open proximal end portion and a distal end portion that includes a port couplable to a lumen-defining device. The pre-sample reservoir is fluidically couplable to the port to receive and isolate a first volume of bodily fluid. The actuator is at least partially disposed in the inner volume and has a proximal end portion that includes an engagement portion and a distal end portion that includes a sealing member. The engagement portion is configured to allow a user to selectively move the actuator between a first configuration such that bodily fluid can flow from the port to the pre-sample reservoir, and a second configuration such that bodily fluid can flow from the port to a sample reservoir defined at least in part by the sealing member and the housing.
