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.
Claims20
A syringe-based device for procuring bodily fluid samples comprising:
- (a) a housing defining an inner volume and being configured to receive fluids;
- and
- (b) an actuator mechanism, the actuator mechanism being movable relative to the housing, the actuator mechanism including;
- (i) a pre-sample container having a proximal end and a distal end, wherein the pre-sample container defines a first fluid reservoir;
- (ii) a removable plunger cap being configured to be operably coupled with the pre-sample container;
- (iii) a plunger tube, the plunger tube being selectively engaged with the removable plunger cap, wherein the removable plunger cap is threadedly coupled with the plunger tube, and wherein the plunger tube includes a cannula assembly;
- and
- (iv) a plunger seal, the plunger seal being movable relative to the housing to define a second fluid reservoir in cooperation with the housing;
- wherein the actuator mechanism transitions from a first configuration in which a first portion of a bodily fluid flows into the first fluid reservoir, to a second configuration in which a second portion of the bodily fluid flows into the second fluid reservoir.

- (ii) a removable plunger cap being configured to be operably coupled with the with the pre-sample container;
- (iii) a plunger tube, the plunger tube being selectively engaged with the removable plunger cap,
- (iv) a cannula assembly retained by the plunger tube;
- and
- (v) a plunger seal, the plunger seal being movable relative to the housing to define a second fluid reservoir in cooperation with the housing;
- wherein the actuator mechanism transitions from a first configuration in which a first portion of a bodily fluid flows into the pre-sample reservoir, to a second configuration in which a second portion of the bodily fluid flows into the second fluid reservoir.
