Abstract
Apparatuses and methods for delivering a fluid, including a viscous fluid. These apparatuses may include a fluid reservoir, two or more piston chambers, a manifold, a delivery port, and a drive assembly and may be configured to inject either a predetermined amount of fluid or a continuous stream of fluid. These apparatuses may also be configured to switch between filling, injection and aspiration modes. These apparatuses may generally be hand-held and lightweight and may provide a significant mechanical advantage to the user.
Claims24
A device for injecting a fluid, the device comprising:
- a reservoir;
- a manifold coupled to the reservoir;
- a first piston chamber configured to be fluidically connected to a reservoir through a manifold;
- a second piston chamber configured to be fluidically connected to the reservoir through the manifold;
- a plurality of check valves in the manifold;
- a delivery port fluidically connected to the first piston chamber and the second piston chamber through the manifold;
- a drive assembly comprising a transmission operatively connected to a first piston in the first piston chamber and a second piston in the second piston chamber, wherein the drive assembly reciprocally moves the first piston and the second piston to drive fluid in a continuous flow out of the delivery port by alternately driving fluid from the second piston chamber and the first piston chamber out of the delivery port while alternately transferring fluid from the reservoir into the first piston chamber and the second piston chamber;
- a motor coupled to the drive assembly and configured to drive the transmission;
- and
- a selector operably coupled to the manifold and configured to select between an injection configuration of the manifold and an aspiration configuration of the manifold, wherein in the injection configuration the delivery port is in fluid communication with the first and second piston chambers, and wherein in the aspiration configuration the delivery port is isolated from the first and second piston chambers and is in communication with a transparent window for viewing a material aspirated.

- a drive assembly comprising a transmission operatively connected to the first piston and to the second piston, wherein the drive assembly reciprocally moves the first piston and the second piston;
- wherein the manifold comprises a first check valve and a second check valve fluidly coupled to an input to the first piston chamber so that when the manifold is in an injection configuration, fluid is passed from the reservoir into the first piston chamber as the first piston is withdrawn in the first piston chamber and fluid is passed from the first piston chamber out of the delivery port when the first piston is advanced in the first piston chamber, wherein the manifold is further configured so that a third check valve and a fourth check valve are fluidly coupled to an input to the second piston chamber so that when the manifold is in the injection configuration, fluid is passed from the reservoir into the second piston chamber as the second piston is withdrawn in the second piston chamber and fluid is passed from the second piston chamber out of the delivery port when the second piston is advanced in the second piston chamber;
- a selector operably coupled to the manifold and configured to select between an injection configuration of the manifold and an aspiration configuration of the manifold, wherein in the injection configuration the delivery port is in fluid communication with the first piston chamber and the second piston chamber and wherein in the aspiration configuration the delivery port isolated from the first and second piston chambers and is in communication with a transparent window for viewing a material aspirated;
- and
- a motor coupled to the drive assembly and configured to drive the transmission.
