The patent-pending EZ-Anesthesia system is designed for the anesthesia of small laboratory animals ranging in size from neonates up to animals weighing 5 kilograms. The system is a portable unit that has been designed for maximum efficiency, ease of use and low anesthetic gas consumption.

The system delivers a precisely blended mixture of oxygen and Isoflurane through a lid unit that covers the polycarbonate host cage.  The lid  includes an activated charcoal air filter canister that releases safe, filtered air back into the room. A water-heated cage warmer helps retains animal body temperature while  in the host cage. 

After initial anesthetizing induction in the host cage, the animal can be moved to the breathing device and heated surgical tray.  Nosecones are custom designed for a range of small animals and are available in three sizes to assure a snug fit with no dead space and no CO2 buildup. A highly sensitive duck valve is regulated by the animal’s  breathing and works in conjunction with the nosecone to assure non-rebreathing efficiency.   

The system allows safe, controlled anesthesia for long surgeries over a period of hours. The breathing device also  incorporates an air filter that releases safe, filtered air back into the room. The gas delivery system can supply anesthesia agent to multiple breathing device units, allowing procedures to be performed simultaneously on several animals.   

The breathing device/surgical bed unit also includes a small soft chamber for anesthetizing a few animals or for holding previously anesthetized animals near the surgical bed. This soft chamber can accommodate up to five mice, keeping them near the surgical bed in an anesthetized condition. This is a convenient alternative to the host cage unit, when only a few animals need to be treated.
