To provide a process and an apparatus for treating a waste anesthetic gas containing a volatile anesthetic and nitrous oxide discharged from an operating room by introducing the gas into an adsorbing cylinder filled with an adsorbent, where the volatile anesthetic contained in the waste anesthetic gas is adsorbed and thereby removed, and successively introducing the gas into a catalyst layer filled with a nitrous oxide decomposition catalyst, where nitrous oxide is decomposed into nitrogen and oxygen. By using the process and the apparatus for treating a waste anesthetic gas of the present invention, a volatile anesthetic having a possibility of destroying the ozone layer or nitrous oxide as a global warming gas can be made harmless while preventing the release into atmosphere.

The invention provides a catalyst obtained by loading at least one noble metal selected from the group consisting of rhodium, ruthenium and palladium on a support selected from silica and silica alumina, and a method for decomposing nitrous oxide using the catalyst thereof. The catalyst for decomposing nitrous oxide of the present invention cannot be easily affected by a volatile anesthetic contained in a waste anesthetic gas, can recover the activity by activation and regeneration even when deteriorated, and can reduce the amount of NOx generated to less than the allowable concentration.

The present invention provides therapeutic formulations, including therapeutic emulsions and nanoemulsions, and related methods for the delivery of fluorinated therapeutic compounds, including an important class of low boiling point perfluorinated and / or perhalogenated volatile anesthetics. Emulsion-based fluorinated volatile anesthetic formulations compatible with intravenous administration are provided that are capable of delivering and releasing amounts of fluorinated volatile anesthetic compounds effective for inducing and maintaining anesthesia in patients. Intravenous delivery of the present emulsion-based fluorinated volatile anesthetic formulations permits anesthetic levels in a patient to be selectively adjusted very rapidly and accurately without the need to hyperventilate patients and without the use of irritating agents.

The present invention provides methods for reducing pain in a subject in need thereof by delivering a volatile anesthetic in a solution or an emulsion that can additionally include an extractive solvent in an amount effective to reduce pain without substantially interfering with motor function. Chronic or acute pain may be treated, or the volatile anesthetic may be delivered as a regional anesthetic to a subject to anesthetize a portion of the subject prior to surgery. Dosing regimes including a one-time administration, continuous and / or periodic administration are contemplated.

An electric continuous flow device of a circulation circuit relates to a continuous flow device of a circulation loop, and solves the problems that a semi-open anesthetic loop for pediatric anesthesia causes low respiratory efficiency, the unutilized oxygen and volatile anesthetics are discharged into the atmosphere, medical resources are wasted, the environment is polluted, and a pediatric anesthetic close circulation loop has large resistance and high respiratory power consumption. A disc flow deflector is fixedly installed on a fan blade and is positioned at one side of an air inlet side, the external diameter of the disc flow deflector is d1, the external diameter of the fan blade is d2, and di equals to d2 minus 4mm; and the control signal output end of a touch screen is connected with the control signal input end of an external rotor electric machine, the signal output end of the external rotor electric machine is connected with the signal input end of the touch screen, the loop inspiration port of a respiration loop is communicated with the inspiration end of a disposable anesthetic loop through the external rotor electric machine, and the loop expiration port of the disposable anesthetic loop is communicated with a respiration loop through a dioxide carbon absorption unit. The electric continuous flow device is used in the anesthetic loop systems for children and adults.

The present invention is concerned with the automated control of the synthesis and purification of components useful in the synthesis and purification of volatile anesthetics. The invention is particularly useful in its application to the purification of acetone used in the purification of isoflurane.
