Abstract

A pump system can include a pump device and a controller device removably attachable to the pump device. The controller device can be reusable, and one or more pump devices can be disconnected and reconnected to the controller device. As such, some pump usage data can be conveniently stored in the pump device itself. In such circumstances, the controller device can receive data related to the pump'"'"'s history or other usage when the pump device is attached to the controller.
