Patent CA-2101138-A1 (CA)
Inventor: FISCHER DAN E
IPC: A61C5/06
Filed: 1993-07-22
Abstract: A syringe device having a barrel enclosing a first chamber therein containing coaxially aligned primary and secondary plungers.  A connectable mixing and delivery tip encloses a second chamber therein and is connected to the barrel by a coupling.  A slidable valve having an aperture therethrough to allow passage of air into and out of the secondchamber is disposed between the two chambers.  The primary plunger is slidable out one end of the syringe for the selective application of pressure into the syringe barrel.   As the primary plunger is urged down into the syringe barrel, air is forced around the secondary plunger and through the valve aperture into the second chamber wherein the substances  contained therein are mixed by turbulent aeration.  Continued application of pressure on the primary plunger drives the secondary plunger into the slidable valve to plug the aperture in the valve thereby ceasing  the  agitation  of  the  contents  in  the  second chamber.  Further urging of the primary plunger drives the secondary plunger and the slidable valve up into the second chamber so that the mixed contents are expelled out of the syringe device through a delivery tip. With such a syringe mixing apparatus, substances can be mixed and expelled from the syringe by continued movement of the primary plunger into the syringe barrel.
