Abstract: A syringe-based apparatus includes a housing having an open proximal end and a distal end, a needle coupled with the distal end of the housing, an actuator mechanism coupled with the housing, the actuator mechanism including a syringe body and a plunger, the syringe body and the plunger being insertable into the open proximal end of the housing. A medicament reservoir is defined at least partially by the housing and the actuator mechanism, and a reconstitution fluid reservoir is defined at least partially by the syringe body and the plunger of the actuator mechanism. The plunger is operably configured to move relative to the syringe body to expel the amount of the fluid from the reconstitution fluid reservoir into the medicament reservoir. The actuator mechanism is operably configured to move relative to the housing to expel the amount of the fluid from the medicament reservoir through the needle.

Abstract: A syringe-based device includes a housing and an actuator mechanism including a first member and a second member. The first member includes a syringe body and a plunger, the plunger being movably disposed within the syringe body. The second member includes a second member plunger seal and a valve operably and selectively coupled to the second member plunger seal such that the valve is positioned proximal of the second member plunger seal. The device also includes a first fluid reservoir and a second fluid reservoir. The device transitions from a first configuration to a second configuration in which the first type of fluid is expelled from the first fluid reservoir, to a third configuration in which the second type of fluid is expelled from the second fluid reservoir through the valve.

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.

Abstract: A syringe-based device includes a housing, the housing including a port, and an actuator mechanism including a first member and a second member configured to be movably disposed within the housing. The first member includes a syringe body and a plunger movably disposed within the syringe body and including a first plunger seal. The second member includes a second plunger seal defining a channel and a valve fluidically coupled with the channel of the second plunger seal. The device also includes a first fluid reservoir and a second fluid reservoir. The device transitions from a first configuration to a second configuration in which a first type of fluid in the first fluid reservoir is delivered through a port, to a third configuration in which a second type of fluid within the second fluid reservoir is delivered through the port.

Abstract: Embodiments include a syringe-based apparatus for delivering fluid, the apparatus comprising a housing having an open proximal end and a distal end defining an inner volume, a needle, an actuator mechanism coupled with the housing, the actuator mechanism comprising a syringe body and a plunger, a medicament reservoir, and a reconstitution fluid reservoir.

Abstract: Embodiments of a syringe-based device for delivering fluid include a housing, a port, the port being positioned at about the distal end of the housing, a plunger assembly, the plunger assembly including, a plunger seal, a valve, and a cannula, a first fluid reservoir, where the first fluid reservoir retains a first type of fluid, a syringe including a syringe body, a syringe port, a plunger, and a second fluid reservoir, the second fluid retaining a second type of fluid, and where the syringe transitions from a first configuration in which a first portion of the first fluid type is delivered through the port, to a second configuration in which the second type of fluid in the second fluid reservoir is delivered through the port, to a third configuration in which a second portion of the first fluid type is delivered through the port.
