Abstract
A syringe-based device for procuring bodily fluid samples can include a housing having a port that can be coupled to a lumen-defining device for receiving bodily fluids, an actuator mechanism including a pre-sample reservoir, a removable plunger cap operably coupled with pre-sample reservoir, a plunger tube, a valve, a plunger seal, and a selectively attachable collection vial for capturing a bodily fluid sample.
Core Innovation
The invention relates to a syringe-based device for procuring bodily fluid samples. A housing defines an inner volume and is configured to receive fluids, and an actuator mechanism moves relative to the housing and transitions between a first configuration and a second configuration to route different portions of bodily fluid into different reservoirs.
In the first configuration, a first portion of a bodily fluid flows into a first fluid reservoir defined by a pre-sample container. The actuator mechanism includes a removable plunger cap operably coupled with the pre-sample container and a plunger tube selectively engaged with the removable plunger cap.
The actuator mechanism further includes a plunger seal movable relative to the housing to define a second fluid reservoir in cooperation with the housing. In the second configuration, a second portion of the bodily fluid flows into the second fluid reservoir, and downstream components such as a sample collection reservoir can be attached so the sample collection reservoir draws the second portion of the bodily fluid.
Claims Coverage
The document includes three independent claims. Across these claims, three main inventive features are repeated: a movable actuator that transitions between two configurations to form two bodily-fluid reservoirs, a pre-sample container coupled to the actuator, and a cannula/plunger-seal arrangement that enables flow into a second fluid reservoir, with optional downstream attachment for sample collection.
Two-configuration reservoir-forming actuator mechanism
A housing defining an inner volume, and an actuator mechanism movable relative to the housing, wherein the actuator mechanism transitions from a first configuration in which a first portion of a bodily fluid flows into a first fluid reservoir to a second configuration in which a second portion of the bodily fluid flows into a second fluid reservoir.
Removable plunger cap and selectively engaged plunger tube
A removable plunger cap operably coupled with a pre-sample container, and a plunger tube selectively engaged with the removable plunger cap.
Cannula assembly and plunger seal defining a second fluid reservoir
A plunger seal movable relative to the housing to define a second fluid reservoir in cooperation with the housing, and a plunger tube that includes a cannula assembly retained by the plunger tube.
Post-removal sample collection reservoir drawing the second portion
A sample collection reservoir that attaches to the cannula assembly after the pre-sample container is removed, such that the sample collection reservoir draws the second portion of the bodily fluid from the second fluid reservoir.
Overall, the independent claims cover a syringe-based bodily-fluid sampling device using a movable actuator that transitions between two configurations to route first and second portions of bodily fluid into first and second reservoirs, using a removable plunger cap with a selectively engaged plunger tube and a plunger seal defining the second reservoir. The claims also recite downstream attachment of a sample collection reservoir that draws the second portion of bodily fluid.
