Dispensing device
A device for dispensing liquid material is disclosed having an ampoule with at least four storage lumens, a mixing tip coupled to a distal end of the storage lumens, and an outlet lumen in fluid communication with storage lumens via the mixing tip. The at least four storage lumens extend axially along the length of an ampoule body, and the mixing tip has at least four gasket seats formed therein, each gasket seat corresponding to one of the storage lumens. The device also includes a first fluid provided in one of the storage lumens and a second fluid having a characteristic different from the first fluid provided in another of the storage lumens. Each of the storage lumens has a proximal gasket sealing the fluids from a proximal end of the ampoule and a distal gasket sealing the fluids from a distal end of the ampoule.
1. A device for dispensing liquid material, comprising:
an ampoule having at least four storage lumens extending axially along the length of an ampoule body, the storage lumens having a diameter in the range of about 0.01 inches to about 0.25 inches;
a mixing tip coupled to a distal end of the storage lumens, the mixing tip having at least four gasket seats formed therein, each gasket seat corresponding to one of the storage lumens;
an outlet lumen in fluid communication with the storage lumens via the mixing tip; and
a first fluid provided in one of the storage lumens and a second fluid having a characteristic different from the first fluid provided in another of the storage lumens, wherein each of the storage lumens has a proximal gasket sealing the fluids from a proximal end of the ampoule and a distal gasket sealing the fluids from a distal end of the ampoule.
2. The device of claim 1 , wherein the first and second fluids are in need of isolation prior to mixing.
3. The device of claim 1 , wherein the first and second fluids are subcomponents of a liquid medicament.
4. The device of claim 1 , wherein the first and second fluids are subcomponents of an adhesive.
5. The device of claim 1 , wherein at least one of the first and second fluids contains a pigment.
6. The device of claim 1 , wherein the distal gaskets have a rounded surface facing the fluids.
7. The device of claim 1 , wherein a mixing channel in the mixing tip couples each of the storage lumens to the outlet lumen.
8. The device of claim 1 , further comprising a plunger assembly coupled to a proximal end of the ampoule in communication with the storage lumens.
9. The device of claim 8 , wherein the plunger assembly comprises at least four pistons, the pistons associated with corresponding storage lumens and receivable therein.
10. The device of claim 8 , wherein the plunger assembly comprises a working fluid dispensing apparatus in fluid communication with the storage lumens.
11. The device of claim 1 , wherein each of the storage lumens has a diameter equal to the others.
12. The device of claim 1 , wherein each of the storage lumens are equidistant from the outlet lumen.
13. The device of claim 1 , wherein the distal gasket has a diameter larger than the diameter of the corresponding storage lumen.
14. The device of claim 1 , wherein the proximal gasket and the distal gasket are constructed of polytetrafluoroethylene.
15. The device of claim 1 , wherein the ampoule has at least twelve storage lumens extending axially along the length of the ampoule body, the mixing tip having at least twelve gasket seats, each gasket seat corresponding to one of the twelve storage lumens.
16. The device of claim 15 , wherein each of the twelve storage lumens has a diameter equal to the others.
17. A kit for dispensing liquid material, comprising:
a dispensing device comprising:
an ampoule having at least four storage lumens having a diameter from about 0.01 inches to about 0.25 inches formed therein extending axially along the length of an ampoule body;
a mixing tip coupled to a distal end of the ampoule body, the mixing tip having a mixing channel and a plurality of gasket seats, each gasket seat aligned with one of the storage lumens;
a first fluid provided in one of the storage lumens and a second fluid having a characteristic different from the first fluid provided in another of the storage lumens, the first and second fluids sealed between a proximal gasket and a distal gasket slidably disposed within each of their respective storage lumens,
wherein when the distal gaskets are seated in the gasket seats, the mixing channel fluidly connects the first and second fluids in the storage lumens to an outlet lumen; and
a plunger assembly configured to couple to a proximal end of the ampoule of the dispensing device, the plunger assembly having at least four pistons, the pistons associated with corresponding storage lumens and receivable therein.
18. The kit of claim 17 , further comprising a dead space in the storage lumens intermediate the distal gasket and the distal gasket seat.
19. The kit of claim 17 , wherein a volume between the outlet lumen and each storage lumen is identical.
20. The kit of claim 17 , wherein the storage lumens are equidistant from the outlet lumen.
