Wireless Communication for On-Body Medical Devices

A method of on-body fluid delivery using a primary user interface communicatively couplable to a primary patch pump,

• wherein the primary patch pump comprises a first reservoir adapted to contain a first fluid, a first cannula, a first pump adapted to infuse the first fluid from the first reservoir through the first cannula, and a first microcontroller adapted to control operations of the first pump,
• the method comprising the steps of:
• pairing the primary patch pump to the primary user interface;
• the primary patch pump communicating with the primary user interface to determine whether user instructions have been received at the primary user interface;
• and
• if it is determined that user instructions have been received at the primary user interface:
• sending machine instructions from the primary user interface to the primary patch pump according to the user instructions;
• and
• initiating a bolus dose or basal rate using the first microcontroller according to the machine instructions.
