SECURED ANESTHETIC DEVICE FOR HIGH RATE MEDICAL SAMPLING ON SMALL LABORATORY ANIMALS

摘要

The invention relates to a dual wall cylindrical container comprising a g as distribution source in the lower portion thereof. The cylindrical contain er is positioned at the lower portion of a frame and comprises at its upper portion two suction sources for potentially pollutant gases. The first sourc e 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 charge d with residual gases, extends from the gap between the upper edge of the op en cylinder and the frame, and is connected to a global network for discharg ing 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 globa l network for discharging and processing the charged air. The gas distributi on source is provided with a safety device that cuts off the supply of said gases when detecting an abnormality in the polluted gases suction circuits.< /SDOAB>
