System, method and apparatus for removal of volatile anesthetics for malignant hyperthermia

A self-contained two-part filter apparatus comprising a housing having a first anesthetic removing filter component configured for attachment to the inspiratory limb of an anesthesia or ventilation system such that the first filter component is in fluid communication with an anesthetic passing through the inspiratory limb, wherein the first anesthetic removing filter component is configured to adsorb and remove anesthetic gas and provide inhaled gas to a patient that is substantially free of anesthetic qas, and a second anesthetic removing filter component configured for attachment to the expiratory limb of an anesthesia or ventilation system such that the second anesthetic removing filter component is in fluid communication with an anesthetic passing through the expiratory limb, and wherein the second anesthetic filter component is configured to adsorb and remove anesthetic gas and prevent release of such anesthetic qas to the patient, wherein the first anesthetic removing filter component and second anesthetic removing filter component are not in fluid communication and are each connected to a separate expiration and inhalation limb.

A system for removing volatile anesthetics from an anesthesia system comprising:

• an anesthesia machine;
• a filter apparatus attachable to the anesthesia machine, the filter apparatus comprising a housing having a first filter chamber comprising a first anesthetic adsorbing and removing filter, wherein the first filter chamber is connected to an inspiratory limb of the ventilation system and the first anesthetic adsorbing and removing filter is configured to adsorb and remove anesthetic gas and provide inhaled gas to a patient that is substantially free of anesthetic gas, and a second filter chamber comprising a second anesthetic adsorbing and removing filter, wherein the second filter chamber is connected to an expiratory limb of the ventilation system and the second anesthetic adsorbing and removing filter is configured to adsorb and remove anesthetic gas and prevent release of such anesthetic gas to the patient, wherein the first filter chamber and second filter chamber are not in fluid communication and are each connected to a separate expiration and inhalation limb;
• wherein the filter apparatus is attached to the anesthesia machine such that the first filter chamber is in fluid communication with the inspiratory limb of the anesthesia machine and the second filter component is in fluid communication with the expiratory limb of the anesthesia machine.
