INTEGRATED MIXING AND DISPENSING APPARATUS
Document Type and Number:
WIPO Patent Application WO2001005321
Kind Code:
B1
Abstract:
A syringe apparatus for mixing and delivering a two-part material has (i) a syringe barrel (12) and a plunger (14). The apparatus also has a paddle (16) slidably coupled to the plunger (14). A distal insertion end (44) of the plunger (14) has a slot (46) therein. A proximal end (51) of the paddle (16) is slidably coupled within the slot (46). The paddle (16) is movable between an extended position and a contracted position with respect to the plunger (14). Upon placing material into the barrel (12), such as through an opening (26) in the wall of the barrel (12), the paddle (16) can be employed to mix the material. After such mixing, the plunger (14) is pressed further into the barrel (12) without removing the paddle (16), thereby expressing the mixed material from the barrel (12) and compressing the paddle (16) into the slot (46) of the plunger.
