Ophthalmic Injection Device Using Piezoelectric Array
First Claim
1. An injection system comprising:
- a tip segment attachable to and removable from a limited reuse assembly;
the tip segment comprising;
a dispensing chamber housing having an inner surface and an outer surface, the inner surface defining a dispensing chamber for receiving a quantity of a substance;
a storage chamber located near the dispensing chamber housing;
a piezoelectric array located between the storage chamber and the dispensing chamber housing;
a needle fluidly coupled to the dispensing chamber; and
a first housing at least partially enclosing the dispensing chamber housing, the storage chamber, and the piezoelectric array;
the limited reuse assembly comprising;
a power source for providing power to the piezoelectric array;
a controller for controlling the power source; and
a second housing at least partially enclosing the power source and the controller;
wherein the piezoelectric array is activated to pump the substance from the storage chamber to the dispensing chamber.

Abstract
An ophthalmic injection device has a dispensing chamber, a storage chamber, a piezoelectric array, a needle fluidly coupled to the dispensing chamber, a power source for providing power to the piezoelectric array, and a controller for controlling the power source. A dispensing chamber housing has an inner surface and an outer surface. The inner surface defines a dispensing chamber for receiving a quantity of a substance. The storage chamber is located near the dispensing chamber housing. The piezoelectric array is located between the storage chamber and the dispensing chamber housing. A housing at least partially encloses the dispensing chamber housing, the storage chamber, the piezoelectric array, the power source, and the controller. The piezoelectric array is activated to pump the substance from the storage chamber to the dispensing chamber.
