Abstract
An apparatus and method for mixing two components and delivering the mixture to a patient. The apparatus contains a mixing chamber for mixing a liquid component and a powder component. The liquid component and powder component are mixed within the mixing chamber by rotation of a collapsible mixing element. A plunger is then advanced through the mixing chamber to force the mixture out of the mixing chamber and deliver the mixture to the patient.
Claims17
A device for mixing two components and dispensing a mixture comprising:
- a mixer section defining a mixing chamber having a first end and a second end;
- a mixing element holder at the first end of the mixing chamber wherein the mixing element holder defines a passageway between the mixing chamber and the exterior of the mixing chamber;
- a collapsible mixing element connected with the mixing element holder and operative to mix a first component and a second component within the mixing chamber;
- and a plunger operative to substantially seal against an interior surface of the mixing chamber wherein the collapsing mixing element collapses at the first end as the plunger is advanced from the second end to the first end, and the mixture is dispensed through the passageway in the mixing element holder.
A device for mixing two components comprising:
- a mixing barrel defining a mixing chamber;
- a liquid component introduction port on the mixing barrel for introducing a liquid component into the mixing chamber;
- a spring holder within the mixing chamber;
- a spring connected with the spring holder operative to rotate about a longitudinal axis of the mixing chamber wherein the spring is the only means for substantially mixing the liquid component and a powder component within the mixing chamber.
A device for mixing two components to form a mixture comprising:
- a mixer section defining a mixing chamber;
- a collapsible mixing element holder within the mixing chamber wherein the collapsible mixing element holder defines a passageway between the mixing chamber and the exterior of the mixing chamber;
- a collapsible mixing element connected to the collapsible mixing element holder operative to rotate about a longitudinal axis of the mixing chamber;
- and a drive shaft operative to engage the passageway of the collapsible mixing element holder wherein rotation of the drive shaft causes rotation of the collapsible mixing element holder.
