Abstract:
A gas reservoir system for use in a breathing circuit, comprising:a first chamber, a second chamber, and a drive mechanism; wherein each said chamber is adapted for containing gas, wherein a volume of each said chamber can be varied, wherein each said chamber has at least one outlet through which said gas is ejected as the volume of said chamber is decreased or drawn in as the volume of said chamber is increased, and wherein the volumes of said first and second chambers are variable by said drive mechanism such that a change in the volume of said first chamber is accompanied by a substantially equal and opposite change in the volume of said second chamber; a diverting adapter comprising a main flow passage, a first diverting passage communicating with said first chamber through said at least one outlet thereof and said main flow passage, and a second diverting passage communicating with said second chamber through said at least one outlet thereof and said main flow passage; and wherein said gas reservoir system is configured for connection to a primary respiratory path of a said breathing circuit for communication of each of said first and second chambers therewith through said main flow passage of said diverting adapter.
