US 2026/0137874 A1 · MEDICATION DELIVERY DEVICE WITH SENSING SYSTEM

Abstract

Medication delivery devices are provided having a housing comprising a reservoir sized sufficiently to hold medication, a dose button being rotatable relative to the housing to select a dose size of the medication for an injection, a printed circuit board, a switch mounted to the printed circuit board, and a controller in communication with the switch. The controller is configured to generate a first count of a set of signals using a first counting technique, generate a second count of the set of signals using a second counting technique, and determine, based on the first and second count, reliability data of the first and/or second count. The controller can connect, using a wireless communication module, to a remote computing device to wirelessly communicate with the remote computing device over an unencrypted wireless communication channel, and transmit, using the wireless communication module, encrypted data to the remote computing device.

Dependent claims

A medication delivery device comprising:

a housing comprising a reservoir sized sufficiently to hold medication;
a dose button being rotatable relative to the housing to select a dose size of the medication for an injection;
a printed circuit board;
a switch mounted to the printed circuit board;
and
a controller in communication with the switch, the controller being configured to:
