Method and device for delivering a subcutaneous dose through multiple injections

A device for administering injections to a patient, the device comprising:

• at least one sensor configured to determine a location of the device relative to a treatment site in the patient;
• a reservoir containing a treatment for the patient;
• an actuator configured to controllably inject a volume of the treatment at one or more depths below the treatment site in the patient;
• a processor configured to determine an appropriate amount of the treatment at a current location detected by the at least one sensor, and to controllably enable or disable operation of the actuator to deliver the treatment in an injection based on the appropriate amount of the treatment at the current location.

An injector comprising:

• a reservoir configured to contain a treatment for administering to a patient;
• a nozzle for dispensing the treatment from the reservoir;
• an actuator configured to controllably inject a volume of the treatment through the nozzle at one or more depths at a treatment site of the patient;
• at least one sensor configured to determine a location of the nozzle relative to the treatment site of the patient;
• and
• a processor configured by computer executable code to perform the steps of:
• determining an appropriate amount of the treatment at a current location detected by the at least one sensor, and
• controllably enable or disable operation of the actuator to deliver the treatment in an injection based on the appropriate amount of the treatment at the current location.
