Multilumen filter

摘要

A multilumen filter device has a housing with first and second filter chambers, each chamber in fluid communication with a separate distal and proximal fluid path. The filter device may be used to provide respiratory gases to and receive expiratory gases from a patient connected to a unilimb respiratory circuit. The filter device may also serve as a connector for respiratory circuit components, and have fasteners or blocking devices at either or both of its distal and proximal ends.
