Abstract
This invention provides for a method and an EMDU used to dispense precise quantities of liquids with an image sensor being capable of providing feedback to the user as to both, when an eye is properly aligned with the EMDU, and to detect and track the quantity of the dose administered on to the eye.
Claims21
Apparatus for dispensing liquid into an Ophthalmic Environment, the apparatus comprising:
- an emitter functional to emit a wavelength of radiation in a direction towards an eye;
- a sensor functional to detect a reflecting wavelength based upon the emitted wavelength, wherein a reflecting wavelength will be different based upon whether the eye comprises an open state or a closed state;
- an automated dispenser for dispensing a liquid towards the eye based upon receipt of a logical signal;
- and
- a processor in logical communication with one or more of the emitter;
- the sensor and the automated dispenser, wherein the processor transmits a logic signal based upon an electrical signal from the sensor indicating whether the eye is in an open state or a closed state.

A method of dispensing a liquid in an Ophthalmic Region, the method comprising;
- aligning an apparatus comprising an emitter functional to emit a wavelength of radiation in a direction towards an eye,
- a sensor functional to detect a reflecting wavelength based upon the emitted wavelength, wherein a reflecting wavelength will be different based upon whether the eye comprises an open state or a closed state,
- an automated dispenser for dispensing a liquid towards the eye based upon receipt of a logical signal and a processor in logical communication with one or more of the emitter;
- the sensor and the automated dispenser, wherein the processor transmits a logic signal based upon an electrical signal from the sensor indicating whether the eye is in an open state or a closed state;
- generating a signal indicating an X, Y, Z alignment position;
- dispensing a liquid via an automated pump based upon the generated signal.
