Abstract
A device for exchanging gas volumes in an anesthetic system has an inlet, an outlet, a first chamber arranged between the inlet and the outlet, a second chamber arranged between the inlet and the outlet, a switching valve for selective connection to the first chamber or the second chamber for forming a flow path between the inlet and the outlet, and a controller for controlling the switching valve.
Claims3
A device for exchanging gas volumes in an anesthetic system, said device comprising:
- an inlet;
- an outlet;
- a first chamber disposed between the inlet and the outlet;
- a second chamber disposed between the inlet and the outlet;
- a switching valve for selectively placing one of said first chamber or said second chamber in fluid communication with said inlet and said outlet to form a flow path between said inlet and said outlet;
- and
- a controller connected to said switching valve for controlling switching of said switching valve.

A tubing system for use in an anesthetic system, said tubing system comprises;
- a unit for adsorption and desorption of gaseous anesthetic;
- an expiration branch adapted for respiratory communication with a respirating subject, said expiration branch being disposed upstream of said unit for adsorption and desorption of gaseous anesthetic;
- and
- a gas volume exchanger connected in said expiration branch, said, gas volume exchanger comprising an inlet and outlet, a first chamber disposed between the inlet and the outlet, a second chamber disposed between the inlet and the outlet, a switching valve for selectively placing one of said first chamber or said second chamber in fluid communication with said inlet and said outlet to form a flow path between said inlet and said outlet, and a controller for controlling switching of said switching valve.

An anesthetic system comprising:
- an anesthetic apparatus and a tubing system adapted to deliver gaseous anesthetic to a respirating subject;
- said tubing system having an expiration branch and a unit for adsorption and desorption on said gaseous anesthetic, said expiration branch being disposed upstream of said unit for adsorption and desorption of said gaseous anesthetic;
- and
- a gas volume exchanger connected in said expiration branch, said gas volume exchanger comprising an inlet, an outlet, a first chamber disposed between the inlet and the outlet, a second chamber disposed between the inlet and the outlet, a switching valve for selectively placing one of said first chamber or said second chamber in fluid communication with said inlet and said outlet to form a flow path between said inlet and said outlet, and a controller for controlling switching of said switching valve.
