In one embodiment, the applicator has a frangible glass vial with the medical adhesive. The frangible glass vial is held in a plastic enclosure with a dispensing tip. Attached to the plastic enclosure is a squeeze tube capable of imparting air pressure into the enclosure. To dispense medical adhesive quickly and with precision, one simply breaks the frangible glass vial and pushes on the squeeze tube. In another embodiment, the applicator has a proximal chamber containing medical adhesive, a distal chamber for dispensing medical adhesive and one or more rupturable membranes between them. To achieve long shelf life, the applicator chambers and membrane(s) are formed from fluorinated plastic. To dispense medical adhesive, one ruptures the membrane(s) and pushes on the sides of the proximal chamber. ## Claims ### Claim 1 A fluid applicator comprising: a fluid containing frangible vial inside a plastic enclosure, wherein said enclosure has an aperture at or near its proximal end; a squeeze tube sealed to the proximal end of said enclosure to generate air pressure through said aperture; and, a dispensing tip at the distal end of said enclosure. ### Claim 2 (depends on 1) The fluid applicator of claim 1 wherein said fluid is a medical adhesive or sealant. ### Claim 3 (depends on 2) The fluid applicator of claim 2 wherein said medical adhesive is 2-octyl cyanoacrylate or formulated 2-octyl cyanoacrylate. ### Claim 4 (depends on 1) The fluid applicator of claim 1 wherein said frangible vial is a frangible glass vial. ### Claim 5 (depends on 2) The fluid applicator of claim 2 wherein said dispensing tip is a porous plug with an accelerator and/or initiator for said medical adhesive. ### Claim 6 (depends on 2) The fluid applicator of claim 2 wherein said dispensing tip has a longitudinal hole or lumen. ### Claim 7 (depends on 6) The fluid applicator of claim 6 further comprising a porous wafer with an accelerator and/or initiator between said frangible vial and said dispensing tip. ### Claim 8 (depends on 1) The fluid applicator of claim 1 further comprising a one-way air valve on said squeeze tube. ### Claim 9 A method for dispensing medical adhesive comprising: selecting a fluid applicator having a fluid containing frangible vial inside a plastic enclosure with an aperture at or near the enclosure's proximal end, a squeeze tube sealed to the proximal end of said enclosure and a dispensing tip at the distal end of said enclosure; squeezing said plastic enclosure to rupture said frangible vial and thereby release fluid from said frangible vial into said plastic enclosure; squeezing said squeeze tube to force air through said aperture and drive fluid through said dispensing tip. ### Claim 10 (depends on 9) The method of claim 9 wherein said fluid is medical adhesive or sealant. ### Claim 11 (depends on 10) The method of claim 10 wherein said medical adhesive is 2-octyl cyanoacrylate or formulated 2-octyl cyanoacrylate. ### Claim 12 (depends on 9) The method of claim 9 wherein said frangible vial is a frangible glass vial. ### Claim 13 (depends on 10) The method of claim 10 wherein said dispensing tip is a porous plug with accelerator and/or initiator for said medical adhesive. ### Claim 14 (depends on 10) The method of claim 10 wherein said dispensing tip has a longitudinal hole or lumen.
