Medical adhesive applicator

Abstract

Medical adhesive applicators are disclosed which allow medical adhesives to have long storage life and be easily dispensed in a controlled manner. 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.

1 - 14 . (canceled) 
     
     
         15 . A fluid applicator comprising:
 a fluid containing proximal chamber;   a fluid dispensing distal chamber having a dispensing tip; and,   one or more rupturable membranes between said chambers with a series of molded radial depressions or weld seams;   wherein said chambers and membrane are formed from fluorinated plastic.   
     
     
         16 . The fluid applicator of  claim 15  wherein said fluid is medical adhesive or sealant. 
     
     
         17 . The fluid applicator of  claim 16  wherein said medical adhesive is 2-octyl cyanoacrylate or formulated 2-octyl cyanoacrylate. 
     
     
         18 . The method of  claim 15  wherein said dispensing tip is a porous plug with an accelerator and/or initiator for said medical adhesive. 
     
     
         19 . The method of  claim 15  wherein said dispensing tip has a longitudinal hole or lumen. 
     
     
         20 . A method for dispensing medical adhesive comprising:
 selecting a fluid applicator having a fluid containing proximal chamber, a fluid dispensing distal chamber with a dispensing tip and one or more reputable membranes between said chambers with a series of molded radial depressions or weld seams, wherein said chambers and membrane are formed from fluorinated plastic.   rupturing said membrane to allow fluid to be released from said proximal chamber into said distal chamber so that it can be dispensed through said dispensing tip.   
     
     
         21 . The method of  claim 20  wherein said fluid is medical adhesive or sealant. 
     
     
         22 . The method of  claim 21  wherein said medical adhesive is 2-octyl cyanoacrylate or formulated 2-octyl cyanoacrylate. 
     
     
         23 . The method of  claim 21  wherein said dispensing tip is a porous plug with accelerator and/or initiator for said medical adhesive. 
     
     
         24 . The method of  claim 20  wherein said dispensing tip has a longitudinal hole or lumen.
