Claim 1
Independent Claim
163 words
A METABOLATOR COMPRISING A CLOSED-CIRCUIT BREATHING SYSTEM INCLUDING A PATIENT UTILIZATION DEVICE, A CARBON DIOXIDE ABSORBER UNIT HAVING INPUT AND OUTPUT, A DEMAND REGULATOR UNIT HAVING A LOW-PRESSURE FLOW SPACE AND A HIGH-PRESSURE FLOW SPACE THEREIN, AN EXHALING DUCT CONNECTING SAID PATIENT UTILIZATION DEVICE TO SAID INPUT, MEANS CONNECTING SAID LOW-PRESSURE FLOW SPACE TO SAID OUTPUTS, AN INHALING DUCT CONNECTING SAID PATIENT UTILIZATION DEVICE TO SAID LOW-PRESSURE FLOW SPACE, A SOURCE OF COMPRESSED OXYGEN CONNECTED TO SAID HIGH-PRESSURE FLOW SPACE, SAID DEMAND REGULATOR UNIT FURTHER INCLUDING A PASSAGE INTERCONNECTING SAID FLOW SPACES, A VALVE NORMALLY CLOSING SAID PASSAGE, AND A VALVE-ACTUATING DEVICE INCLUDING MEANS RESPONSIVE TO THE DIFFERENTIAL OF AMBIENT ATMOSPHERIC PRESSURE AND PRESSURE IN SAID LOW-PRESSURE FLOW SPACE AND OPERABLE TO OPEN SAID VALVE WHEN SUCH LATTER PRESSURE DROPS BY A PREDETERMINED AMOUNT BELOW SUCH AMBIENT ATMOSPHERIC PRESSURE, THERBY CONTINUOUSLY TO PROVIDE OXYGEN AT SUBSTANTIALLY ATMOSPHERIC PRESSURE TO THE PATIENT, AND MEANS TO MEASURE THE QUANTITY OF OXYGEN CONSUMED BY THE PATIENT.
