Patent ID: 7503323

Claim:
A gas delivery system capable of delivering an anesthesia gas to a plurality of gas outlets, the system comprising: an oxygen inlet that receives oxygen from an oxygen source; a pressure regulator having an inlet that receives oxygen from the oxygen inlet and having an outlet that provides oxygen at a lower pressure; an anesthesia gas source having an inlet coupled to receive low pressure oxygen from the outlet of the pressure regulator and capable of adding anesthesia gas to the low pressure oxygen; a first gas delivery outlet coupled to a gas delivery device having multiple living specimen interfaces horizontally disposed along a front face of the gas delivery device and capable of simultaneously providing anesthesia gas and oxygen to the multiple living specimen interfaces, wherein the at least one channel comprises a buffer volume configured to substantially reduce flow rate fluctuations from the multiple specimen interfaces, wherein the first gas delivery outlet comprises an outlet port and a first flow control disposed between the anesthesia gas source and the outlet port; a plurality of holes surrounding the multiple living specimen interfaces capable of drawing in anesthesia gas; and a slot disposed between two adjacent multiple living specimen interfaces, wherein the slot is capable of receiving an opaque light barrier, wherein the opaque light barrier prevents light being emitted by one living specimen interface from reaching an adjacent living specimen interface.
