Claim Text:
1. A dispensing device for dispensing fresh gas, oxygen and anesthetic in an anesthesia device for connection to a patient, the dispensing device comprising: an anesthetic evaporator with an inlet and an outlet; a device oxygen gas port; a mixer with an oxygen port, which is connected to said device oxygen gas port via a fluidic path branch, with a nitrous oxide port and with an air port, wherein nitrous oxide, oxygen and air are mixed in said mixer and wherein mixed gas can reach the inlet of the anesthetic evaporator; an oxygen-dispensing and display element, which is connected to said device oxygen gas port via another fluidic path branch and which has an adjusting element for adjusting a rate of flow and which displays the rate of flow; a switching element, wherein said switching element is arranged downstream of said oxygen-dispensing and display element; a gas tapping port provided for connecting a tube or tube and mask combination for oxygen insufflation; a connection and port element for the patient; a first gas path; and a second gas path, wherein said first gas path is arranged downstream of said switching element, said second gas path is arranged downstream of said switching element, said first gas path leads to the inlet of the anesthetic evaporator and from said anesthetic evaporator to said connection and port element for the patient, said second gas path leads to said gas tapping port, said switching element sending oxygen, which is sent from the oxygen-dispensing and display element arranged upstream of said switching element to said switching element, into said first gas path or into said second gas path, and oxygen reaches said connection and port element while flowing through said first gas path after flowing through said anesthetic evaporator and oxygen is available at said gas tapping port during flow through said second gas path, wherein: said switching element sends oxygen without overlap either into said first gas path or into said second gas path; and there is no state of the switching element in which oxygen simultaneously enters said first gas path and said second gas path.
