15 Claims

1. A gas delivery device configured to provide anesthesia gas and oxygen to multiple living specimens in an imaging box configured to simultaneously image multiple specimens in the imaging box with light, wherein the imaging box has a door and a plurality of walls thereby forming an interior cavity, the gas delivery device comprising an inlet for receiving anesthesia gas and oxygen, multiple living specimen interfaces configured to provide anesthesia gas and oxygen to the multiple living specimens when the gas delivery device is inside the imaging box, and at least one channel for communicating anesthesia gas and oxygen between the inlet and the multiple specimen interfaces, wherein the at least one channel comprises a buffer volume sufficiently large to substantially reduce flow rate fluctuations to the multiple specimen interfaces.
