1. A fluid infusion device, comprising:
- a housing having a reservoir chamber that receives a fluid reservoir and a pump chamber;
a drive system contained within the pump chamber of the housing and a slide of the drive system is movable relative to the fluid reservoir for dispensing fluid from the fluid reservoir;
a seal disposed between the reservoir chamber and the pump chamber that defines an opening and the slide is movable relative to the seal through the opening; and
a pressure management system at least partially defined in the slide of the drive system, the pressure management system including at least one air conduit that cooperates with the opening of the seal to vent air from the reservoir chamber into the pump chamber.

Abstract
Systems for managing pressure in a fluid reservoir chamber of a fluid infusion device are provided. For example, a fluid infusion device comprises a housing having a chamber for receiving a fluid reservoir. The fluid infusion device also comprises a drive system contained within the housing. A portion of the drive system is movable for dispensing fluid from the fluid reservoir. The fluid infusion device comprises a pressure management system at least partially defined in the portion of the drive system to vent air from the chamber.

8. A fluid infusion device, comprising:
-
a housing having a reservoir chamber and a pump chamber; a fluid reservoir contained within the reservoir chamber of the housing; a connector body coupled to the housing and the fluid reservoir to define a fluid flow path out of the housing, the connector body including one or more vents to vent air from the reservoir chamber; a drive system contained within the pump chamber of the housing and coupled to the fluid reservoir, the drive system including a slide movable relative to the fluid reservoir to dispense fluid from the fluid reservoir; a seal disposed between the reservoir chamber and the pump chamber that defines an opening and the slide is movable relative to the seal through the opening; and a pressure management system at least partially defined in the slide of the drive system, the pressure management system including at least one air conduit that cooperates with the opening of the seal to vent air from the reservoir chamber into the pump chamber. - View Dependent Claims (9, 10, 11)
