Patent ID: 8632511

Claim:
An ophthalmic injection device, comprising: a tip segment, comprising: a dispensing chamber; a temperature feedback layer, formed of a flexible insulation material, comprising: a first thermal sensor comprising sensory traces in the insulation material; a second thermal sensor comprising sensory traces in the insulation material; wherein the temperature feedback layer is wrapped around the dispensing chamber to thermally couple the first and second thermal sensors to the dispensing chamber; a temperature control layer coupled to the dispensing chamber; a dispensing assembly coupled to the tip segment, comprising: an actuator configured to control dispensing of precise quantities of drugs from the dispensing chamber; wherein the actuator is at least a motor that is coupled to a shaft that delivers a drug; a processing device located on either the tip segment or the dispensing assembly; wherein the processing device is configured to receive temperature information from the first thermal sensor and the second thermal sensor and wherein the processing device is configured to control the temperature control layer at least partially based on the received temperature information.
