Patent number: 11547785Abstract: An extracorporeal blood gas exchange device has a bloodstream area for guiding a bloodstream, a gas-carrying area for guiding a gas flow, and a membrane, which forms a gas-liquid barrier between the bloodstream and the gas flow, and which further makes possible the transfer of carbon dioxide of the bloodstream into the gas flow. The device further has at least one measuring cuvette, which is separated from the bloodstream area at least partially by the membrane, so that carbon dioxide of the bloodstream can pass over into the measuring cuvette. The device has an optical measuring unit, which is configured to measure a carbon dioxide partial pressure present in the measuring cuvette.Type: GrantFiled: December 12, 2017Date of Patent: January 10, 2023Assignee: Drägerwerk AG & Co.

Patent number: 10926048Abstract: With the interaction of a medical measuring system (3) with a ventilator or anesthesia device (5) via a data network (60), data transmission security and mutual authentication between the medical measuring system (3) and the ventilator or anesthesia device (5) is improved in a medical system (1) by the use of asymmetric encryption pairs. A classification of the measuring systems (3) is possible on the basis of an identification/authentication provided by the asymmetric encryption pairs. The classification may be used to adapt a ventilation by the ventilator or anesthesia device (5) in respect to different defined measuring systems (3), for example, measuring systems (3) for detecting an oxygen saturation (SpO2).Type: GrantFiled: March 21, 2018Date of Patent: February 23, 2021Assignee: DRÄGER WERK AG & CO.

Patent number: 9254368Abstract: A process and a device for oxygen regulation of a patient having at least two SPO2 monitors and a control for automatic recognition of which measurements are more reliable. The measurement from one or more of the two SPO2 is used to control the oxygen concentration delivered to a patient based on a comparison of the measurements from the at least two SPO2 monitors.Type: GrantFiled: December 2, 2011Date of Patent: February 9, 2016Assignee: DRÄGERWERK AG & CO. KGaAInventors: Tilman von Blumenthal, Donald Null

Patent number: 8718954Abstract: A process for controlling the delivery of a quantity of gas to be measured through a test gas tube (60) with a pump (20), a sensor system for pressure and flow measurement (12, 14, 16) and a control and regulating unit (30). A common mode offset of a differential pressure sensor (14), determined in a calibration process, is taken into account in the process for operating the gas sampling device to increase the accuracy of a gas volume being delivered with pump (20) from the measuring environment (50).Type: GrantFiled: June 27, 2011Date of Patent: May 6, 2014Assignee: Dräger Safety AG & Co. KGaAInventor: Tilman von Blumenthal

Patent number: 8696588Abstract: A device (1) and a corresponding method are provided for determining and/or monitoring the respiration rate based on measurement with more than one sensor (5, 7, 9, 13, 15). The device may be part of a monitor for determining and/or monitoring the respiration rate. The second and/or additional sensors are different form the first sensor and have a different manor of operation from the first sensor.Type: GrantFiled: October 24, 2007Date of Patent: April 15, 2014Assignee: Dräger Medical GmbHInventors: Hans-Ullrich Hansmann, Tilman von Blumenthal, Peter Tschuncky, Andreas Hengstenberg, Frank Mett, Uwe Kühn, Frank Franz, Kai Kück, Steffen Schmitt

Patent number: 8528552Abstract: A device and a process for controlling a respirator with inclusion of an oxygen saturation value (34) for compensating a device-dependent time response (15), a physiological time response (16) and a measuring method-dependent time response (17) are described. The device-dependent time response (15), the physiological time response (16) and the measuring method-dependent time response (17) are determined in a continuous sequence and a run time of a change in the oxygen concentration from the metering means (9) in the respirator to the patient (4) is determined and taken into account in regulating the oxygen concentration.Type: GrantFiled: November 30, 2009Date of Patent: September 10, 2013Assignee: Dräger Medical GmbHInventor: Tilman von Blumenthal

Patent number: 8047205Abstract: A gas-mixing device for respirators can be used both in stationary operation and in mobile operation. The gas-mixing device has a storage tank (5), into which compressed air and oxygen can be introduced by dispensing valves (3, 8). In addition, a blower (10), which draws in gas from the environment (11), is connected to the storage tank (5). To dispense gas from the pressurized gas sources (4, 6) by means of the dispensing valves (3, 8), a first operating pressure level is set in the storage tank (5). When changing over to the blower operation, the operating pressure level is lowered to a pressure level adapted to the maximum respiration pressure.Type: GrantFiled: November 8, 2007Date of Patent: November 1, 2011Assignee: Dräger Medical GmbHInventors: Tilman von Blumenthal, Judith Löser, Ralf Lorenzen, Bernhard Ludwig, Frank Oelgarth

Patent number: 7442181Abstract: A device and system for dispensing medical active ingredients. Medical active ingredients may be, e.g., drugs or anesthetics, which enter the patient's bloodstream. Injection pumps and perfusors are usually used for their dispensing, and vapors are frequently used in the case of inhalation anesthetics. The device permits the dispensing of a plurality of medical active ingredients, in which the rates of dispensing can be set precisely and changed with rapid action. This is accomplished by the series connection of a plurality of devices according to the present invention, which are designed as modules. Each module comprises a cartridge (6) as well as a delivery device (8) for delivering the particular medical active ingredient to be administered to a fluid interface (18), which leads to a supply line (16) designed either as an infusion line or as a respiration tube. The module has a coupling means (9, 10, 11, 12).Type: GrantFiled: December 17, 2003Date of Patent: October 28, 2008Assignee: Dräger Medical AG & Co.
