Claim:
A fluid infusion device that delivers a medication fluid to a body, the fluid infusion device comprising: a base plate; a delivery conduit coupled to the base plate, wherein the delivery conduit provides the medication fluid to the body; and a self-sealing reservoir port receptacle located on the base plate, the self-sealing reservoir port receptacle comprising an inlet to receive a fluid delivery port of a fluid reservoir, a valve chamber in fluid communication with the inlet, a valve element located in the valve chamber, and an outlet between the valve chamber and the delivery conduit; wherein: when the fluid delivery port is disengaged from the self-sealing reservoir port receptacle, the valve element is biased toward the inlet into a sealed position to form a fluid seal between the valve element and the inlet; the outlet provides a fluid flow path for the medication fluid; when the fluid delivery port is engaged with the self-sealing reservoir port receptacle, an end of the fluid delivery port moves the valve element from the sealed position to an opened position to accommodate flow of the medication fluid from the fluid reservoir into the valve chamber; and the valve element comprises a ball valve.
