Abstract:
1. A portable and wearable insulin pump system, comprising: a disposable and non-reusable pump device having a drive system to dispense insulin, the pump device including: a pump housing that defines a space to receive an insulin cartridge, a cap device that connects with the pump housing to enclose the insulin cartridge in the pump housing when the insulin cartridge is received in the space, and a retainer structure that is different from the cap device and that extends into the space to engage a portion of the medicine cartridge and thereby hinder removal of the insulin cartridge when the insulin cartridge is received in the space such that the insulin cartridge is non-removable from the disposable and non-reusable pump device; a reusable controller device removably attached to the pump device and being different from the cap device of the pump device, the controller device including: a controller housing matable with the pump housing structure to form a releasable mechanical connection, control circuitry positioned in the controller housing that electrically transmits control signals to the drive system positioned in the pump housing to dispense insulin at a dispensation rate when the controller device is removably attached to the pump device, the controller device including a user interface; and an accelerometer arranged in controller housing of the reusable controller device and electrically connected to the control circuitry such that the accelerometer is external to the pump housing of the pump device, the accelerometer providing signals indicative of activity levels of the user; wherein the controller device automatically adjusts the dispensation rate based at least in part on the signals of the accelerometer indicative of the activity levels of the user, and wherein the controller device automatically reduces a basal rate of insulin if signals of the accelerometer indicate an increased activity level.
