A DEVICE, AN AGGREGATE AND A METHOD FOR PROVIDING A GASIFIED ANESTHETIC AGENT

摘要

A respiratory anesthetic aggregate (1) devised for coupling to a breathing apparatus (100) is disclosed. The aggregate (1) comprises an anesthetic gasifier unit that has a breathing gas input port connected to a first point in an inspiratory patient gas delivery path of a breathing apparatus, and a fresh gas output port connected to a second point in the patient gas delivery path downstream the first point. The inspiratory patient gas delivery path is connected via a mainstream connection between the first and second point. Thereby the anesthetic gasifier unit is connected in a sidestream configuration to the patient gas delivery path for adding the gasified anesthetic agent in a desired concentration to the patient gas delivery path at the second point. The aggregate is devised for external coupling to a breathing apparatus. In this manner, a substantially volume neutral delivery of anesthetic agent is provided for a breathing apparatus.
