1. A wearable infusion pump assembly comprising:
- a reusable housing assembly;
a disposable housing assembly comprising a base, a reservoir formed at least partly by the base to be integral to the disposable housing assembly, the reservoir for receiving an infusible fluid, and a fluid path extending through the disposable housing and connected to the reservoir;
a releasable engagement assembly configured to allow the reusable housing assembly to releasably engage the disposable housing assembly;
a detachable external infusion set including tubing connected to the fluid path of the disposable housing assembly and configured to receive infusible fluid from the reservoir through the fluid path and to deliver the infusible fluid to a user;
a bolus switch on the reusable housing assembly, the bolus switch configured to effectuate a bolus infusion event;
at least one processor; and
a computer readable medium coupled to the at least one processor, the computer readable medium including a plurality of instructions stored thereon which, when executed by the at least one processor, cause the at least one processor to perform operations comprising;
receiving an initiation signal from the bolus switch indicative of a bolus infusion event;
receiving a dose signal from the bolus switch indicative of at least a portion of a bolus quantity of the infusible fluid;
rendering an audible quantity signal in response to the dose signal; and
receiving an approval signal from the bolus switch indicative of a concurrence with the audible quantity signal.
