Abstract
Embodiments of the invention relate to a multi-syringe device where a coupling element causes a plurality of plungers to slide in unison within their respective barrels to simultaneously dispense fluids therefrom. At least one of the plungers is a variable-length plunger that is selectively engagable to the coupling element.
Claims37
A system for delivery of fluids, the system comprising:
- a. a syringe assembly comprising like-oriented first and second syringes to define a dispensing direction, each syringe having a respective plunger slidable within a respective syringe barrel, the plunger of the second syringe having an adjustable length;
- and
- b. a coupling element attached to and mechanically engaged to the plunger of the first syringe so that:
- i. lengthening or shortening of the adjustable-length plunger of the second syringe respectively causes the adjustable-length plunger of the second syringe to mechanically engage to or disengage from the coupling element;
- and
- ii. motion of the coupling element in the dispensing direction causes each mechanically engaged plunger to longitudinally slide within its respective syringe barrel to move in unison with the coupling element.

A system for delivery of fluids, the system comprising:
- a. a syringe assembly comprising like-oriented first and second syringes to define a dispensing direction, each syringe having a respective plunger slidable within a respective syringe barrel;
- and
- b. a coupling element attached to and mechanically engaged to the plunger of the first syringe, the plunger of the second syringe having adjustable length and being selectively engagable to the coupling element such that:
- i. when the system is in a first configuration, there is clearance between the plunger of the second syringe and the coupling element so that the plunger of the second syringe is disengaged from the coupling element;
- ii. when the system is in a second configuration, plungers of the first and second syringes are simultaneously engaged to the coupling element and motion of coupling element in the dispensing direction causes each engaged plunger to longitudinally slide within its respective syringe barrel to move in unison with the coupling element.

A system for delivery of fluids, the system comprising:
- a syringe having an adjustable length plunger slidable within a respective syringe barrel.
A method for delivery of fluids comprising:
- providing a syringe assembly comprising:
- i. like-oriented first and second syringes to define a dispensing direction, each syringe having a respective plunger slidable within a respective syringe barrel the plunger of the second syringe having an adjustable length;
- and
- ii. a coupling element attached to and mechanically engaged to the plunger of the first syringe
- lengthening or shortening of the adjustable-length plunger of the second syringe so as to causes the adjustable-length plunger of the second syringe to mechanically engage to or disengage from the coupling element;
- and
- moving coupling element in the dispensing direction so as to cause each engaged plunger to longitudinally slide within its respective syringe barrel to move in unison with the coupling element and thereby causing fluid to be simultaneously expelled from the barrels.
