Abstract: The invention relates to a dual wall cylindrical container with a gas distribution source in the lower portion thereof. The cylindrical container is positioned at the lower portion of a frame with two suction sources for potentially pollutant gases. The first source has the highest gas charge and extends from the space defined by the dual wall of the cylinder and is connected to an active-carbon dynamic extraction system. The second source extends from the gap between the upper edge of the open cylinder and the frame, and is connected to a global network for discharging and processing the charged air. A third suction source extends from the two horizontal work planes provided with sieves for suction from the top to the bottom. The gas distribution source is provided with a safety device that cuts off the supply of gases when detecting an abnormality in the suction circuits.

Abstract: The invention relates to equipment for a small laboratory animal designed to keep it under volatile anesthesia then to insert it into an imaging system for medical imaging investigations. It makes sure the vigilant animal has pre-anesthesia by means of a direct induction device of anesthetizing gas, its anesthesia prolonged by means of the usable device for keeping it in the open or closed position. This device makes direct access possible by the blood or respiratory pathway. The temperature of the animal is controlled and modulated by means of a nonmagnetic heat exchanger. The invention takes into account the safety of the users in regard to their exposure to halogens thanks to the double sealing connection system and thanks to the induction device that does not impregnate the coat of the animal that they have to handle.

Abstract: The invention relates to a dual wall cylindrical container comprising a gas distribution source in the lower portion thereof. The cylindrical container is positioned at the lower portion of a frame and comprises at its upper portion two suction sources for potentially pollutant gases. The first source has the highest gas charge and extends from the space defined by the dual wall of the cylinder and is connected to an active-carbon dynamic extraction system. The second source, which is located at an upper level and is charged with residual gases, extends from the gap between the upper edge of the open cylinder and the frame, and is connected to a global network for discharging and processing the charged air. A third suction source extends from two horizontal work planes provided with sieves for suction from the top to the bottom. This last residual gas suction source is also connected to the global network for discharging and processing the charged air.
