Patent number: 11975237Abstract: The present invention relates to a respiratory therapy system having two respiratory therapy devices operable separately and independently of one another. The respiratory therapy devices each have a control unit and each have a device component controllable by means of the control unit for providing a device function. In this case, a coupling unit is provided for establishing an operational connection between the respiratory therapy devices. The coupling unit is designed for the purpose of controlling the control units of the respiratory therapy devices when the operational connection is established.Type: GrantFiled: December 20, 2018Date of Patent: May 7, 2024Assignee: LOEWENSTEIN MEDICAL TECHNOLOGY S.A.Inventors: Bjoern Tiemann, Christof Goebel, Anne Wonsyld, Thomas Ress, Benjamin Adametz, Jan Schattner

Patent number: 11660411Abstract: A respiratory device having a respiratory gas source, a control unit and a connecting device for connecting to a respiratory mask. The control unit is connected to a sensor for detecting a measurement parameter. The control unit has a step generator for specifying a stepped modification of the pressure that is generated by the respiratory gas source. The sensor measures a signal that corresponds to the pressure distribution and is coupled to an analyzer that evaluates the temporal distribution of an analysis signal that is dependent on the measuring signal. The step generator increases the pressure by a pressure step in a respiratory cycle that follows the measuring evaluation, if the analyzer determines a deviation of the analysis signal from a limit value after a predeterminable time limit has elapsed following the pressure increase. The deviation must exceed a predeterminable minimum differential in order to trigger a pressure increase.Type: GrantFiled: March 18, 2019Date of Patent: May 30, 2023Assignee: Loewenstein Medical Technology S.A.Inventors: Wolfgang Wedler, Bjoern Tiemann, Christof Goebel

Publication number: 20200338289Abstract: A system and method for supplying respiratory gas comprises a ventilation device comprising a respiratory gas source and a control device configured for generating a defined respiratory gas flow for ventilation by the ventilation device and for monitoring a parameter characteristic of a pressure by a sensor device. The parameter characterizes that pressure at which the ventilation device admits the respiratory gas stream for maintaining the defined respiratory gas flow in order to counterbalance breathing activity of the patient. The control device is configured for registering a course of the parameter over time as a pressure profile.Type: ApplicationFiled: April 20, 2020Publication date: October 29, 2020Inventors: Matthias SCHWAIBOLD, Bjoern TIEMANN, Christof GOEBEL, Benno DOEMER, Benjamin ADAMETZ
