Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.

The fluid infusion device of claim 9, wherein the port opening comprises at least one flow path that allows the medication fluid to flow from the fluid conduit and into the valve chamber when the valve element is in the opened position. 14. The fluid infusion device of claim 13, wherein the at least one flow path comprises a plurality of channels defined in a rim of the fluid delivery port, and the plurality of channels are spaced apart along a perimeter of the rim. 15. The fluid infusion device of claim 9, wherein the medication fluid comprises insulin. 16. The fluid infusion device of claim 9, wherein an end of the fluid delivery port moves the valve element into the opened position. 17. A fluid infusion device that delivers a medication fluid to a body, the fluid infusion device comprising: a fluid reservoir comprising a main body section that defines a fluid chamber for the medication fluid, and comprising a fluid delivery port coupled to and extending from the main body section, the fluid delivery port comprising a fluid conduit that communicates with the fluid chamber, and the fluid delivery port terminating at an unsealed port opening, the port opening including a plurality of flow paths that allow the medication fluid to flow from the fluid conduit;a self-sealing reservoir port receptacle for the fluid delivery port, comprising an inlet to receive the fluid delivery port, a valve chamber in fluid communication with the inlet, a valve element located in the valve chamber, the valve element biased toward the inlet to form a fluid seal between the valve element and the inlet, and an outlet in fluid communication with the valve chamber to provide a fluid flow path for the medication fluid; anda sealing element disposed in the inlet to form a seal with an outer surface of the fluid delivery port;wherein engagement of the fluid delivery port with the inlet moves the valve element from a sealed position at the inlet to an opened position to accommodate flow of the medication fluid into the valve chamber, and the medication fluid flows from the fluid conduit through the plurality of flow paths and into the valve chamber.
