Patent number: 11763700Abstract: An airway simulation system includes a simulated airway having a hollow body defining a passageway therein with a first portion and a second portion. The second portion includes a bifurcated section having a left branch section and a right branch section and connects to the first portion at the distal end of the first portion. The simulated airway includes at least one orifice defined along the hollow body and in communication with at least one pressure transducer. One branch of the left branch section and the right branch section is configured to receive airflow from a distal end, and the other of the left branch section and the right branched section includes a cap at a distal end to prevent airflow from being received by the distal end of the capped branch. A method for simulating a human airway is also disclosed.Type: GrantFiled: October 27, 2022Date of Patent: September 19, 2023Assignee: IngMar Medical, Ltd.Inventors: Stefan Frembgen, James J. Fialho, Joel Neatrour

Patent number: 9463292Abstract: 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.Type: GrantFiled: September 14, 2011Date of Patent: October 11, 2016Assignee: IngMar Medical, Ltd.Inventor: Stefan Frembgen

Patent number: 7959443Abstract: 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.Type: GrantFiled: September 12, 2006Date of Patent: June 14, 2011Assignee: IngMar Medical, Ltd.Inventors: Stefan Frembgen, Maik Gremme

Patent number: 5316542Abstract: 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.Type: GrantFiled: February 11, 1993Date of Patent: May 31, 1994Assignee: Dragerwerk AktiengesellschaftInventors: Jochim Koch, Stefan Frembgen
