Methods and apparatus enabling coupling of an electronics unit to a base unit of a continuous analyte monitoring device

A method of coupling an electronics unit to a base unit of a wearable device of a continuous analyte monitoring system, comprising:

• retaining the electronics unit to a carrier of a coupling tool by use of a carrier retention device;
• positioning the electronics unit adjacent the base unit;
• engaging the carrier retention device with an activator of the coupling tool, the activator comprising a first member comprising a first end configured to contact the electronics unit, a contact member comprising a second end configured to contact at least a portion of the carrier retention device, and a top portion directly attached to the first member and the contact member,
• wherein engaging the carrier retention device with the activator releases the electronics unit from the carrier retention device;
• and
• coupling the electronics unit to the base unit by contacting the electronics unit with the first end,
• wherein the top portion is configured to be pressed by a user during coupling of the electronics unit to the base unit.

A coupling tool, comprising:

• a carrier;
• a carrier retention device attached to the carrier, the carrier retention device comprising a first arm and a second arm configured to retain an electronics unit to the carrier;
• and
• an activator comprising:
• a first member comprising a first end configured to contact the electronics unit to couple the electronics unit to a base unit of a wearable device of a continuous analyte monitor;
• a contact member comprising a second end configured to contact at least a portion of the carrier retention device to thereby release the electronics unit from the carrier retention device;
• and
• a top portion directly attached to the first member and the contact member and configured to be pressed by a user during coupling of the electronics unit to the base unit.
