A medical device for infusing medical substances has activation buttons accessible on an exterior of a device housing. The activation buttons and corresponding electrical switches within the device housing are configured to prevent inadvertent activation of the activation buttons and therefore inadvertent operation of the corresponding electrical switches to initiate a process such as the infusion of medical substance(s) to a user. The medical device employs overlap of respective time traces initiated by activation of the activation buttons to determine whether the activation is intended and valid. These respective time traces do not have to be initiated simultaneously or in any particular sequence. The activation buttons can be elastomeric overmolded buttons set within cutouts in the device housing, and, when depressed, make physical contact with the corresponding electrical switches.

Activation system and method for on-body medical devices

A medical device for infusing medical substances has activation buttons accessible on an exterior of a device housing. The activation buttons and corresponding electrical switches within the housing are configured to prevent inadvertent activation of the buttons and therefore inadvertent operation of the switches to initiate a process such as medical substance delivery to a user. The device employs overlap of respective time traces initiated by activation of the activation buttons to determine whether the activation is intended and valid. The respective time traces do not have to be initiated simultaneously or in any particular sequence. The activation buttons can be elastomeric overmolded buttons set within cutouts in the housing, and, when depressed, make physical contact with respective switches.
