초록 ▼

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.

대표청구항 ▼

A syringe apparatus comprising: barrel means forming first and second chambers, said second chambers adapted for receiving first and second substances to be mixed therein; valve means situated in the barrel means between the first and second chambers for providing passage of air into and out of the second chamber; and plunger means, slidably disposed in said barrel means, for sealing the valve means to prevent passage of air therethrough and for expelling the mixed substances from said second chamber as said plunger means is pushed into said barrel means, and wherein said plunger means comprises: a first plunger member comprising a distal end with a piston mounted thereon, the distal end and piston being slidably disposed within said first chamber; and a second plunger means separate and unattached from the first plunger member so as to be moveable only in tandem with the first plunger member once contacted by the first plunger member, and comprising a distal end for contacting the valve means and for sealing the valve means as said contact is made, and further comprising a proximal end slidably situated in said first chamber so as to be contacted by said piston at the distal end of the first plunger member, the distal end of said second plunger member thereafter being moveable through said second chamber by continued movement of the first plunger member.
