Infusion pump device with venting feature

摘要

An infusion device for infusion of a fluid from a reservoir into a body, the infusion device being connectable to an infusion set adaptor at a connecting site, the infusion device comprising: a drive mechanism to operatively couple with at least a portion of the reservoir; a housing being sized to contain at least a portion of the reservoir, wherein the drive mechanism is at least partially or fully contained within the housing; a sealing device that permits the passage of air into and out of the housing or a housing compartment and inhibits the passage of liquids into the housing or a housing compartment through the sealing device; wherein the sealing device is arranged at the drive mechanism or at a location between a part of the drive mechanism and the connecting site of the infusion set adaptor or at the connecting site of the infusion set adaptor.

1. An infusion device for infusion of a fluid from a reservoir into a body, the infusion device being connectable to an infusion set adaptor, the infusion device comprising:
a drive mechanism for operatively coupling with at least a portion of the reservoir; a housing comprising two or more compartments, at least one being configured to contain at least a portion of the reservoir and another configured to at least partially or fully contain the drive mechanism; a sealing device configured to permit passage of air into and out of a first compartment of or within the housing and to inhibit passage of liquids through the sealing device between the first compartment and a neighboring compartment of or within the housing; a connecting site for operatively coupling the infusion set adaptor; wherein the sealing device is arranged at a location between the first compartment and the neighboring compartment and such location is part of a path for movement of air between compartments of or within the housing whereby such movement equalizes pressure between such compartments.
