The invention provides an 
inhalation-
anesthesia exposing and monitoring device, which comprises an 
oxygen or air-
oxygen mixed-gas tank, an 
inhalation-
anesthetic volatilizing tank, carrier-gas pipes, a gas inlet hole, an 
inhalation-
anesthetic exposing box, a gas outlet hole, an 
anesthetic-gas adsorber used in a loop, a multi-parameter anesthetic-gas monitor, an 
animal body-temperature maintainer, a line, a line access hole, a dissecting 
microscope, a constant-temperature heating plate, a small-mouse fixing hole, an invasive 
arterial blood-pressure monitor, a heat-preserving 
blanket and an 
operating table, wherein the 
oxygen or air-oxygen mixed-gas tank, the inhalation-anesthetic volatilizing tank, the inhalation-anesthetic exposing box and the anesthetic-gas adsorber are connected with the multi-parameter anesthetic-gas monitor through the carrier-gas pipes, and the 
animal body-temperature maintainer is connected with the heat-preserving 
blanket. The experiments of a plurality of large / small mice can be simultaneously carried out with sufficient and sensitive heat preservation, real-time monitoring and self-heating, and the 
breathing conditions of the large / small mice under an anesthetic state are observed at any moment. The inhalation-
anesthesia exposing and monitoring device has the advantages of reasonable design, simplicity and convenience in operation and strong 
controllability and not only has the function of anesthetic-concentration monitoring, but also is provided with an anesthetic absorbing device, so that the inhalation-
anesthesia exposing and monitoring device is safe and 
environmentally friendly.
