Abstract
Embodiments of 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 retained at least partially within the housing, the actuator mechanism including a pre-sample reservoir, a plunger operably coupled with pre-sample reservoir, a plunger cap, a plunger tube, a valve, a plunger seal, an a selectively attachable collection vial for capturing a bodily fluid sample.
Claims20
A syringe-based device for procuring bodily fluid samples comprising:
- (a) a housing including a proximal end portion and a distal end portion and defining an inner volume therebetween, the proximal end portion being open and the distal end portion having a port configured to be coupled to a lumen-defining device configured to receive bodily fluids;
- and
- (b) an actuator mechanism including a proximal end portion and a distal end portion, the actuator mechanism being retained at least partially within the inner volume defined by the housing and movable relative to the housing, the actuator mechanism including;
- (i) a pre-sample reservoir having a proximal end and a distal end, wherein the pre-sample reservoir is fluidically coupleable to the port and defines a first fluid reservoir;
- (ii) a plunger having a proximal end and a distal end, the distal end of the plunger being associated with the proximal end of the pre-sample reservoir such that distal movement of the plunger correspondingly moves the pre-sample reservoir distally, wherein the plunger includes at least one projection;
- (iii) a removable plunger cap, the removable plunger cap defining a cavity, wherein the plunger translates within the cavity defined by the removable plunger cap until the at least one projection engages a catch such that the removable plunger cap and the plunger are coupled when the at least one projection engages the catch;
- (iv) a plunger tube, the plunger tube being selectively engaged with the removable plunger cap, wherein the plunger tube includes a shrouded cannula assembly;
- (v) a valve, the valve being coupled with an attachment element of the plunger tube such that the valve is fluidically coupled with the shrouded cannula assembly;
- and
- (vi) a plunger seal, the plunger seal being coupled with the valve and plunger tube, wherein the plunger seal is movable relative to the housing to at least partially define a second fluid reservoir;
- and
- Wherein the actuator mechanism transitions from a first configuration in which a bodily fluid flows from the port to the first fluid reservoir, and a second configuration in which the bodily fluid flows from the port to the second fluid reservoir.

A syringe-based device for procuring bodily fluid samples comprising:
- (a) a housing including a proximal end portion and a distal end portion and defining an inner volume therebetween, the proximal end portion being substantially open and the distal end portion having a port configured to be coupled to a lumen-defining device for receiving bodily fluids;
- and
- (b) an actuator mechanism including a proximal end portion and a distal end portion, the actuator mechanism being retained at least partially within the inner volume defined by the housing and movable relative to the housing, the actuator mechanism including;
- (i) a pre-sample reservoir having a proximal end and a distal end, wherein the pre-sample reservoir defines a first fluid reservoir and is selectively detachable from the actuator mechanism;
- (ii) a plunger having a proximal end and a distal end, the distal end of the plunger being operably connected with the proximal end of the pre-sample reservoir such that distal movement of the plunger correspondingly moves the pre-sample reservoir distally;
- (iii) a removable plunger cap, the removable plunger cap defining a cavity, wherein the plunger translates within the cavity defined by the removable plunger cap;
- (iv) a plunger tube, the plunger tube being selectively engaged with the removable plunger cap, wherein the plunger tube includes a cannula assembly;
- (v) a valve, the valve being coupled with the plunger tube such that the valve is fluidically coupled with cannula assembly;
- (vi) a plunger seal, the plunger seal being coupled with the plunger tube and removable plunger cap, wherein the plunger seal is movable relative to the housing to define a second fluid reservoir;
- and
- (vii) a collection vial, wherein the collection vial is inserted into the plunger tube after the removal of the pre-sample reservoir such that the bodily fluid in the second fluid reservoir is collected;
- and
- Wherein the actuator mechanism transitions from a first configuration in which a bodily fluid flows from the port to the first fluid reservoir, and a second configuration in which the bodily fluid flows from the port to the second fluid reservoir.
