DEVICE FOR THE STUDY OF SLEEP DISTURBANCES ON LABORATORY ANIMALS

摘要

The device is characterized in that it comprises, in combination, a horizontal circular plate (1) for supporting animals (2), driven in rotation about a vertical axis (3), a cylindrical wall (4) whose outer diameter is substantially equal to that of the turntable (1), this wall delimiting an internal confinement space (7) forming a cage for housing animals moving freely on the plate, an intermediate partition (12), fixed, s extending into the cylindrical wall (4) by dividing the internal confinement space into two opposite compartments (13, 14), an upper closure lid (15), preferably removable, secured to the intermediate partition (12) and extending parallel to the plate (1), and a system (36) for supplying a breathing gas through the closure lid (15) for the animals (2) present in the two opposite compartments (13, 14) of the confinement space (7).
