  • Publication number: 20210353193
    Abstract: 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.

  • Publication number: 20210275068
    Abstract: An apparatus includes a housing defining an inner volume, a distal coupler at least temporarily coupled to a distal end portion of the housing and configured to be placed in fluid communication with a bodily fluid source, a fluid communicator disposed in the inner volume, and a lock coupled to the housing. The lock is transitionable between a first configuration in which the lock couples the distal coupler to housing such that a portion of the fluid communicator extends through a seal of the distal coupler to place the distal coupler in fluid communication with a proximal end portion of the housing and a second configuration in which the lock allows for removal of the distal coupler. The lock is configured to be transitioned back to the first configuration after removing the distal coupler to limit access to the fluid communicator via the distal end portion of the housing.

  • Patent number: 11076787
    Abstract: 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.

  • Publication number: 20210186392
    Abstract: 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.

  • Publication number: 20200253524
    Abstract: 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.
