Patent number: 9555204Abstract: A method for controlling the end-expiratory pressure at a patient (30) in a respiratory system (50) of an anesthesia apparatus or respirator (30) includes regulating a pressure curve (401a, 401b, 501a, 501b) during the expiration phase (650) of the patient such that the pressure curve is described by an at least partially dropping curve (105a, 105b, 106a, 106b, 601, 602, 603, 604) from a first upper pressure value (613a, 613b, 613c, 613d) to a first lower pressure value (614a, 614b, 614c, 614d) from the end of the inspiration phase (660) until the beginning of the next, following inspiration phase (670). An anesthesia apparatus or respirator is provided that includes an operating and actuating unit that regulates a controllable expiratory valve and a respiration drive such that the pressure curve is described by an at least partially dropping curve.Type: GrantFiled: February 3, 2012Date of Patent: January 31, 2017Assignee: Drägerwerk AG & Co.

Publication number: 20160346497Abstract: A ventilator or anesthesia device and method create a reference state and record a measured value as a reference value. A gas delivery unit is activated after the ending of the reference state to build up pressure in a breathing circuit. A comparison measured value is determined with a pressure or flow sensor. A deviation of the measured value from the reference value in relation to a predefined or predefinable expected value is monitored based on the comparison. A warning message is issued depending on a result of the comparison. A drop in pressure in the breathing circuit is caused after the recording of the comparison measured value and a further comparison measured value is recorded following the drop in pressure. A deviation of the further comparison measured value from the reference value leads to a further warning message when the deviation does not correspond to the further expected value.Type: ApplicationFiled: May 19, 2016Publication date: December 1, 2016Inventors: Ralf HEESCH, Robert SCHMID, Jonas BÖRNER

Patent number: 8997741Abstract: A respiration system feeds an anesthetic gas having, a density ?gas, with a Y-piece for connection to a patient, with a respiration circuit having an inspiration branch and an expiration branch, which extend away from the Y-piece. A first supply line from a branch in the expiration branch leads to an anesthetic gas discharge valve and a second supply line from the branch leads to a reservoir. A too high pressure, opposing expiration, cannot build up in the expiration branch and losses of anesthetic gas are kept to a minimum. A prestressing device exerts a prestressing force onto the valve body of the anesthetic gas discharge valve against the effect of gravity. The mass mvalve and the prestressing force determine a threshold pressure in the anesthetic gas discharge line that results in an opening of the anesthetic gas discharge valve.Type: GrantFiled: January 27, 2012Date of Patent: April 7, 2015Assignee: Dräger Medical GmbHInventors: Ralf Heesch, Henryk Schnaars
