    摘要: The invention is directed to a method for controlling the operating parameters determining the thermal metabolism of a premature or newborn disposed in an incubator. These operating parameters include the incubator air temperature and the incubator humidity. The method is improved in such a manner that the adjustment of the parameters is coupled to the combination thereof optimizing the thermal metabolism without the necessity of a complex multiple step adjustment for each individual parameter. The method is characterized in that a primary control circuit for controlling the first parameter supplies the actual value corresponding thereto as a control parameter to a logic generator which determines a sequence value by means of a logic function. This sequence value is conducted to a secondary circuit as a desired value for the adjustment of the second parameter.

    摘要: A respiratory metabolic simulator includes a cell that produces CO2 and depletes O2, e.g., a direct methanol fuel cell having an external electrical circuit. An electric load is applied to the external electrical circuit of the direct methanol fuel cell to vary the electrical load applied to the external electrical circuit of the direct methanol fuel cell to produce carbon dioxide. The carbon dioxide generated by the direct methanol fuel cell is supplied to respiration gases produced by the respiratory metabolic simulator. The direct methanol fuel cell is also used to remove oxygen from the respiration gases prior to mixing the respiration gases and the carbon dioxide.

    摘要: A system and method of delivering CO2 in a respiration closed-loop control system to a respiratory simulator includes (a) providing a CO2 supply to a respiratory simulator having a piston/cylinder arrangement; (b) providing flow control hardware between the CO2 supply and the piston/cylinder arrangement; (c) generating a first control signal representative of a predefined amount of CO2; and (d) providing the predefined amount of CO2 into the piston/cylinder arrangement. Thereafter, either (i) an end-tidal carbon dioxide partial pressure (EtCO2) value is determined based on an amount of CO2 emptied from the piston/cylinder arrangement during an exhalation phase of the respiratory simulator or (ii) an EtCO2 value is calculated via an equation. A second control signal is generated that is representative of a tidal volume and a breathing frequency representative of a physiological response to the EtCO2 value to effect corresponding movement of the piston in a next inhalation and exhalation phase.
