Medication delivery devices, systems and methods

A method of delivering medication using a medication delivery device, the medication delivery device comprising one or more user interface elements, control circuitry, and a memory, the method comprising:

• receiving, via the medication delivery device, analyte measurement data of a user;
• presenting, via the one or more user interface elements, information related to the analyte measurement data to the user;
• determining an intended dose of medication based on the analyte measurement data;
• querying the user to indicate that the user is ready for delivering medication without presenting the intended dose on any of the one or more user interface elements of the medication delivery device;
• and
• automatically delivering the intended dose after receiving the user's indication.

A medication delivery device comprising:

• a housing configured to receive a medication cartridge, the medication cartridge extending between a distal end and a proximal end thereof and including a vial having a septum at the distal end and a displacement member inside the vial and movable from the proximal end to the distal end to deliver medication received by the vial from the distal end;
• a drive mechanism inside the housing configured to advance the displacement member within the medication cartridge to deliver medication when the medication cartridge is received in the housing;
• one or more location sensors positioned to detect a location of the displacement member within the medication cartridge when the medication cartridge is received in the housing;
• and
• control circuitry configured to:
• determine an intended dose of medication to be delivered,
• obtain information from the one or more locations sensors, the information indicating the location of the displacement member within the medication cartridge,
• determine a first position of the displacement member within the medication cartridge based on the information from the one or more location sensors, wherein the first position identifies the location of the displacement member before delivery of the dose of medication,
• determine a second position of the displacement member within the medication device based on the intended dose of medication to be delivered, the second position indicating a desired location of the displacement member within the medication cartridge after delivery of the dose of medication,
• instruct the drive mechanism to advance the displacement member from the first position, and
• instruct the drive mechanism to cease advancing the displacement member upon obtaining the information from the one or more location sensors indicating that the displacement member has reached the second position.

A method of delivering medication using a medication delivery device that includes a housing configured to receive a medication cartridge, the medication cartridge extending between a distal end and a proximal end thereof and including a vial having a septum at the distal end and a displacement member inside the vial and movable from the proximal end to the distal end to deliver medication received by the vial from the distal end, the medication delivery device further including a drive mechanism inside the housing configured to advance the displacement member within the medication cartridge to deliver medication when the medication cartridge is received in the housing, one or more location sensors positioned to detect a location of the displacement member within the medication cartridge, and control circuitry configured to control operation of the medication delivery device, the method comprising:

• the control circuitry determining an intended dose of medication to be delivered;
• the one or more location sensors detecting a location of the displacement member within the medication cartridge and providing information indicating the location of the medication cartridge to the control circuitry;
• the control circuitry obtaining the information from the one or more locations sensors indicating the location of the displacement member within the medication cartridge;
• the control circuitry determining a first position of the displacement member within the medication cartridge based on the information from the one or more location sensors, wherein the first position identifies the location of the displacement member before delivery of the dose of medication;
• the control circuitry determining a second position of the displacement member within the medication device based on the intended dose of medication to be delivered, the second position indicating a desired location of the displacement member within the medication cartridge after delivery of the dose of medication;
• the control circuitry instructing the drive mechanism to advance the displacement member from the first position;
• and
• the control circuitry instructing the drive mechanism to cease advancing the displacement member upon obtaining the information from the one or more location sensors indicating that the displacement member has reached the second position.
