Fluid reservoir having a fluid delivery needle for a fluid infusion device

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;
• a fluid reservoir comprising a main body section that defines a fluid chamber for the medication fluid, a hollow fluid delivery needle terminating at a needle end and extending from the main body section and defining a fluid conduit that communicates with the fluid chamber, and a U-shaped needle hood extending from the main body section and partially surrounding the hollow fluid delivery needle, the U-shaped needle hood terminating at a lip that extends further from the main body section than the needle end, and the U-shaped needle hood comprising integrally formed opposing guide rails extending therefrom, the opposing guide rails serving as an alignment structure for the fluid reservoir;
• and
• a reservoir port receptacle located on the base plate and comprising mating structure to engage and mate with the opposing guide rails of the U-shaped needle hood, a sealing element to receive the hollow fluid delivery needle and form a seal around an exterior surface of the hollow fluid delivery needle, and an outlet conduit at least partially defined by the sealing element, wherein the outlet conduit is coupled to the delivery conduit, wherein the opposing guide rails align and orient the hollow fluid delivery needle relative to the reservoir port receptacle for insertion of the hollow fluid delivery needle into the sealing element of the reservoir port receptacle.
