The invention relates to a regenerative absorber device (20) for the removal of CO.sub.2 from expiration gases during anesthesia. The device comprises a container (38) having an inlet (39) for said expiration gases, and an outlet (41) for output gases, the CO.sub.2 content of which having been substantially removed therefrom. The device is provided with an ion exchanger (42) having the capability to absorb CO.sub.2, disposed in said container (38) such that the gases flow through said ion exchanger from said inlet (39) to said outlet (41). A novel method of anesthesia comprises use of a CO.sub.2 absorber device according to the invention.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
