Ophthalmic injection system
First Claim
1. An ophthalmic 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 partially defining a dispensing chamber for holding a quantity of a substance;
a plunger engaged with the inner surface of the dispensing chamber housing, the plunger capable of sliding in the dispensing chamber housing, the plunger fluidly sealed to the inner surface of the dispensing chamber housing, the plunger having a plunger interface;
a needle fluidly coupled to the dispensing chamber;
a temperature control device at least partially surrounding the dispensing chamber housing, the temperature control device for altering a temperature of the substance in the dispensing chamber;
a thermal sensor located near the dispensing chamber housing, the thermal sensor for measuring a temperature near the dispensing chamber housing;
a memory device;
a first pair of tip interface connectors located on an interfacing surface of the tip segment, the first pair of tip interface connectors electrically coupled to the temperature control device;
a second pair of tip interface connectors located on the interfacing surface of the disposable injection device, the second pair of tip interface connectors electrically coupled to the thermal sensor;
a third pair of tip interface connectors located on the interfacing surface of the disposable injection device, the third pair of tip interface connectors electrically coupled to the memory device; and
a first housing at least partially enclosing the dispensing chamber housing, the temperature control device and the plungerthe limited reuse assembly comprising;
an actuator having a shaft;
a power source for providing power to the actuator;
a controller for controlling the actuator;
a mechanical linkage interface coupled to the shaft, the mechanical linkage interface having a mating surface on an end, the mating surface for interfacing with the plunger interface;
a pair of limited reuse assembly interface connectors located on an interfacing surface of the limited reuse assembly;
a displacement sensor for measuring a distance the actuator shaft travels;
an interface for connecting the displacement sensor to the controller; and
a second housing at least partially enclosing the power source, the controller, and the actuator;
wherein the substance is injected after the temperature of the substance is altered.

Abstract
An ophthalmic injection system has a tip segment attachable to and removable from a limited reuse assembly. The tip segment has a dispensing chamber housing, a plunger, a needle, a temperature control device, a thermal sensor, and a first housing at least partially enclosing the dispensing chamber housing, the temperature control device and the plunger. The limited reuse assembly has an actuator with a shaft, a power source for providing power to the actuator, a controller for controlling the actuator, a mechanical linkage interface, and a second housing at least partially enclosing the power source, the controller, and the actuator. The mechanical linkage interface is coupled to the actuator shaft and has a mating surface on one end. The substance is injected after the temperature of the substance is altered.
