  • Method and apparatus for the reuse of anesthetic gases in inhalation anesthesia with specific size and position of CO.sub.2 absorber
    Patent number: 5471979
    Abstract: A method and apparatus for the re-use of anesthetic gases which are not absorbed by a patient, in inhalation anesthesia make use of an adsorption filter during exhalation, the unused anesthetic gases being subsequently desorbed from the adsorption filter during inhalation, and being reintroduced into the respiration flow to the patient. The exhaled gas is supplied through an absorber for carbon dioxide before it is re-supplied to the patient. The apparatus includes a common line for the delivery and discharge of anesthesia and respiration gases to and from a patient. An adsorption filter for adsorption and desorption of anesthetic gases is arranged in this line.
