TORONTO – A Halifax, Nova Scotia-based med-tech company has patented a device that removes CO? from anesthetic equipment in the OR in a way that is safer, more long-lasting and environmentally friendlier than conventional chemical absorbers. The Memsorb is the brain child of anesthesiologist and Dmf Medical Inc. CMO Michael Schmidt who said anesthetizing patients during a long procedure can produce an amount of CO2 equivalent to 7,500 kilometers of travel in a car.
