First Claim:
Show all 15 claims
What is claimed as new and desired to be protected by Letters Patent of the United States is:     1. A medical gas outlet system for delivering a medical gas from a supply of the gas according to at least two different non-redundant keying schemes, wherein the first non-redundant keying scheme has a plurality of first adapter types keyed to corresponding specific gas types, each of the first adapters including a valve nose through which the medical gas is received, and including a first gas-specific type of keying structure unique to a corresponding specific gas, and wherein the second non-redundant keying scheme has a plurality of second adapter types keyed to corresponding specific gas types, each of the second adapters including a valve nose through which the medical gas is received, and including a second gas-specific type of keying structure unique to a corresponding specific gas and different from the first type of gas-specific keying structure, said outlet system comprising:
  • a valve aperture sized to accept the valve nose of the first or second adapters and to guide the nose into engagement with a gas valve, said valve aperture being opened by engaging with the nose;
  • a first gas-specific outlet-indexing structure to mate with the first gas-specific adapter keying structure to permit the nose of the plurality of adapters of the first non-redundant keying scheme of the corresponding gas to be inserted into said valve aperture;
  • a second gas-specific outlet-indexing structure to mate with the second gas-specific adapter keying structure to permit the nose of the plurality of adapters of the second non-redundant keying scheme to be inserted into said valve aperture; and
  • a seal positioned to inhibit the medical gas from leaking when the gas flows from the gas supply to the nose of the first or second adapter types.
