Surgical teams are often exposed to anesthetic gases that "leak" the masks of patients undergoing surgery. There are diseases and consequences associated with this long-term exposure. In thinking of the welfare of surgical teams, was thought, designed and conceived ULTRASEG, which is our aspiration of anesthetic gases plant. This plant removes from breathing air any mixture of anesthetic gas, and it can be installed in any location, where are provided nitrous oxide terminals. It is an extremely compact, modular construction and allows that one system is in operation while the other is in reserve or maintenance. Is also classified as a medical device and complies with various quality standards.
