Abstract
A sealing assembly is utilized for a fluid infusion device that cooperates with a fluid reservoir having a reservoir port and a hollow fluid reservoir needle at least partially located within the reservoir port. The sealing assembly has a reservoir port receptacle with a proximal end, a distal end extending from the proximal end, and a needle opening formed in the distal end to receive the hollow fluid reservoir needle. The sealing assembly also has a fluid chamber located at least partially in the reservoir port receptacle, and a needle sealing element having a self-sealing needle opening formed therein. The needle sealing element is located within the reservoir port receptacle between the distal end and the fluid chamber. The self-sealing needle opening accommodates the hollow fluid reservoir needle when the reservoir port engages the reservoir port receptacle.
