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 being configured to receive fluids;
- and
- (b) an actuator mechanism, the actuator mechanism being retainable at least partially within 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 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.
