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.

Fluid control devices and methods of using the same

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reservoir can be fluidically coupled to a delivery member to receive and isolate a predetermined volume of bodily-fluid withdrawn from a patient.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.

Fluid diversion mechanism for bodily-fluid sampling

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.

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.

Sterile bodily-fluid collection device and methods

A system for verifying a sample volume includes a sample reservoir and a volumetric verification device. The sample reservoir defines an inner volume and is configured to receive a volume of bodily fluid. The inner volume of the sample reservoir contains an additive. The volumetric verification device includes a first indicator and a second indicator. The volumetric verification device is configured to selectively engage the sample reservoir to (1) place the first indicator in a first position along a length of the sample reservoir such that the first indicator is substantially aligned with a surface and/or meniscus of the additive and (2) place the second indicator in a second position along the length of the sample reservoir such that the second indicator is substantially aligned with a predetermined fill volume when bodily fluid is transferred to the inner volume.

Devices and methods for verifying a sample volume

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.

The present technology relates generally to cough-assist devices with humidified cough assistance. In one example, a system includes a cough-assist device having a first phase configured to provide insufflating gas to a patient circuit and a second phase configured to draw exsufflating gas from the patient circuit. A humidifier is disposed between the cough-assist device and a distal end of the patient circuit, the humidifier including a chamber configured to contain heated water and fluidically coupled to the cough-assist device and the patient circuit. The system further includes a bypass configured to (a) direct insufflating gas from the cough-assist device through a first route to the patient circuit such that the insufflating gas is humidified in the chamber, and (b) route exsufflating gas from the patient circuit through a second route to the cough-assist device such that the exsufflating gas bypasses the chamber.

Cough-assist systems with humidifier bypass

An apparatus includes a housing, a fluid reservoir, a flow control mechanism, and an actuator. The housing defines an inner volume and has an inlet port that can be fluidically coupled to a patient and an outlet port. The fluid reservoir is disposed in the inner volume to receive and isolate a first volume of a bodily-fluid. The flow control mechanism is rotatable in the housing from a first configuration, in which a first lumen places the inlet port is in fluid communication with the fluid reservoir, and a second configuration, in which a second lumen places the inlet port in fluid communication with the outlet port. The actuator is configured to create a negative pressure in the fluid reservoir and is configured to rotate the flow control mechanism from the first configuration to the second configuration after the first volume of bodily-fluid is received in the fluid reservoir.

A catheter inserter () including an actuator assembly () to move a catheter assembly outside a housing () by engaging the catheter assembly multiple times, in an example. The inserter includes a needle assembly () in a housing that has a first position with a needle extending from the housing and a second position with the needle retracted into the housing. A catheter assembly () is removably positioned in the housing and includes a catheter () and a hub () connected to the catheter. An actuator assembly () is further mounted to the housing and operates to selectively engage a guidewire assembly to move the guidewire past the needle and to selectively engage the catheter assembly to move the catheter and the hub outside the housing.

Catheter insertion system

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.

Systems and methods for delivering a fluid to a patient with reduced contamination

A collection system configured to maintain the integrity of a bodily fluid sample has a proximal end portion, a distal end portion, and an inner surface defining a fluid flow path therethrough. The distal end portion is configured to be placed in fluid communication with a patient. The proximal end portion is configured to be placed in fluid communication with a fluid reservoir. The fluid flow path defined by the inner surface is associated with at least one flow characteristic configured to limit a stress within the flow of the bodily fluid between the distal end portion and the proximal end portion.

Systems and methods for sample collection with reduced hemolysis

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.
