  • Patent number: 12150763
    Abstract: 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.

  • Patent number: 12133968
    Abstract: 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.

  • Publication number: 20240315623
    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.

  • Patent number: 12083234
    Abstract: An apparatus includes a fluid reservoir, a sterilization member, and a transfer adapter. The sterilization member operably couples to the fluid reservoir. The sterilization member is configured to be transitioned between a first configuration, in which the sterilization member obstructs an inlet surface of the fluid reservoir and maintains the inlet surface in a substantially sterile environment, and a second configuration, in which the inlet surface is unobstructed. The transfer adapter is configured to be placed in fluid communication with a portion of a patient. The transfer adapter is configured to move relative to the sterilization member from a first position to a second position such that a surface of the transfer adapter contacts the sterilization member to transition the sterilization member to the second configuration. The fluid reservoir is placed in fluid communication with the transfer adapter when the transfer adapter is in the second position.

  • Publication number: 20240057908
    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.
