    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: An apparatus includes a pre-sample reservoir, a diversion mechanism, and a flow metering mechanism. The diversion mechanism has an inlet port couplable to a lumen-defining device to receive bodily-fluids from a patient, a first outlet port fluidically couplable to the pre-sample reservoir, and a second outlet port fluidically couplable to a sample reservoir. The diversion mechanism defines a first fluid flow path and a second flow path that are configured to place the first outlet port and the second outlet port, respectively, in fluid communication with the inlet port. The flow metering mechanism is configured to meter a flow of a predetermined volume of bodily-fluid through the first fluid flow path into the pre-sample reservoir, to meter a flow of a second volume of bodily-fluid through the second fluid flow path into the sample reservoir, and to display a volumetric indicator associated with the predetermined volume and the second volume.

    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.

    摘要: An apparatus 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. A sequestration portion can be configured to receive an initial volume of bodily fluid. A flow controller disposed in the sequestration portion can be configured to transition from a first state to a second state in response to contact with the initial volume of bodily fluid. As the flow controller transitions, a negative pressure differential can be defined that is operable to draw the initial volume of bodily fluid into the sequestration portion. When the flow controller is in the second state, the negative pressure differential can be substantially equalized such that (1) the sequestration portion sequesters the initial volume and (2) a subsequent volume of bodily fluid can be transferred from the inlet to the outlet.

    摘要: An apparatus for procuring bodily fluid samples with reduced contamination includes a housing having a sequestration chamber, an inlet, and an outlet. A flow controller defines a portion of the sequestration chamber and can transition—in response to a suction force exerted by a fluid collection device fluidically coupled to the outlet—from a first state in which the sequestration chamber has a first volume to a second state in which the sequestration chamber has a second volume greater than the first volume, to draw an initial volume of bodily fluid into the sequestration chamber. An actuator is coupled to the housing and is in fluid communication with the inlet and the sequestration chamber in a first configuration, and is transitioned to a second configuration to sequester the sequestration chamber from the inlet, and allow a subsequent volume of bodily fluid to flow from the inlet to the outlet.

    摘要: A device includes a pre-sample reservoir, an actuator mechanism, and a diverter. The pre-sample reservoir can be fluidically coupled to a delivery member to receive and isolate a predetermined volume of bodily-fluid withdrawn from a patient. The actuator mechanism is operably coupled to the pre-sample reservoir such that, when actuated, a negative pressure is formed in the pre-sample reservoir that urges the bodily-fluid to flow into the pre-sample reservoir. The diverter can selectively control fluid flow between the delivery member and the pre-sample reservoir. The diverter includes a flow control mechanism that defines a first fluid flow path and a second fluid flow path. The diverter is movable between a first configuration in which the bodily-fluid flows through the first fluid flow path to the pre-sample reservoir, and a second configuration in which the bodily-fluid flows through the second fluid flow path to a sample reservoir coupled to the diverter.
