Publication number: 20240118160Abstract: A device and a process detect a leak during artificial ventilation of a patient. A measurement system with a sensor arrangement and a sensor fluid guide unit is monitored. A fluid connection is established between a patient-side coupling unit and a medical device with a patient fluid guide unit. A gas sample is branched off from the patient fluid guide unit and guided through the sensor fluid guide unit to the sensor arrangement. A thermal conductivity time course of the gas sample reaching the sensor arrangement is determined with sensor arrangement measured values. Depending on a temporal change in the determined thermal conductivity, a decision is made as to whether there is an indication of a leak between the patient's fluid-guiding unit and the sensor arrangement. The leak establishes a fluid connection between the sensor fluid guide unit and/or the sensor arrangement and the environment.Type: ApplicationFiled: September 28, 2023Publication date: April 11, 2024Inventors: Gerd PETER, Bernd-Michael DICKS, Tobias HEISE, Robert JAHNS, Martin KROH

Patent number: 11555780Abstract: A photoacoustic sensor (100) is capable of detecting a predefined target gas in an area (Um). A process is capable of detecting the target gas with the use of such a sensor (100). A sample chamber (3) holds a gas sample (Gp) to be tested. Electromagnetic waves (eW) from a radiation source (1) pass through the sample chamber (3) and the detection chamber (4). The waves elicit in the detection chamber (4) an acoustic effect, which is measured by an acoustic sensor (7). The acoustic effect is correlated with the concentration of the target gas in the sample chamber (3). The detection chamber (4) is fluid-tightly sealed, is free from target gas and is filled with a replacement gas (Eg). The transmission of the replacement gas (Eg) has a spectral response similar to that of the transmission of the target gas in a predefined target gas wavelength range.Type: GrantFiled: July 20, 2021Date of Patent: January 17, 2023Assignee: Drägerwerk AG & Co.

Patent number: 11154216Abstract: A device (1) for determining the concentration of a gas component is configured with a radiation source (30) for radiating (31) light as a light emission in an infrared wavelength range. Two detector arrays (52, 62) with two detector elements (50, 60) are configured suitably for detecting the light emission generated by the radiation source (30) in two detector arrays (52, 62). Two filter elements (51, 61) are associated with the detector elements (50, 60). The two detector elements (50, 60) are oriented in relation to the radiation source, so that a range of overlap (65) is obtained due to the two detector arrays (52, 62). The range of overlap (65) causes attenuations in the propagation of light, which may be due to gas molecules or moisture (400). The attenuations in the propagation of light affect both detector elements (50, 60) and are compensated concerning the determination of the concentration.Type: GrantFiled: October 27, 2017Date of Patent: October 26, 2021Assignee: Drägerwerk AG & Co.

Patent number: 10502682Abstract: A device (1) for determining the concentration of a gas component is configured with a radiation source (30) for emitting (31) a light radiation or heat radiation in an infrared wavelength range. A detector array (40) has at least two detector elements (50, 60), configured to detect the radiation generated by the radiation source (30), in an angular arrangement (52, 62) and with filter elements (51, 61). At least one of the two detector elements (50, 60) is oriented in an angular arrangement (52, 62) in relation to a vertical axis (32), so that a range of overlap (65) is obtained due to the angular arrangements (52, 62). The range of overlap (65) causes attenuations in the propagation of light, which attenuations may be due, for example, to gas molecules or moisture (400), affect both detector elements (50, 60) and are thus compensated concerning the concentration determination.Type: GrantFiled: October 27, 2017Date of Patent: December 10, 2019Assignee: Drägerwerk AG & Co.

Publication number: 20100278200Abstract: The output of a mode-locked solid-state NIR laser having a pulse duration less than 50 picoseconds at a pulse-repetition frequency is frequency doubled in a nonlinear crystal to provide green radiation. The green radiation is type-I frequency doubled in a BBO crystal to provide UV radiation. The green radiation is focused into an elliptical spot in the BBO crystal with the major axis of the spot in the walk-off plane of the crystal. The length of the crystal is chosen to be much less than the Rayleigh range of the green radiation in the walk-off plane of the BBO crystal.Type: ApplicationFiled: May 4, 2009Publication date: November 4, 2010Applicant: Coherent, Inc.Inventors: Bernd-Michael Dicks, Ruediger Von Elm
