Publication number: 20230181860Abstract: An airway adaptor providing a measurement chamber for gas measurement by a mainstream gas analyzer includes a body having a first end and a second end and configured to connect in a ventilation circuit carrying ventilation gas to and from a patient. The body forms a primary path that includes the measurement chamber and is configured to allow ventilation gas to pass between the first end and the second end and at least one secondary path separated from the primary path and located on an outer perimeter of the primary path. The at least one secondary path is configured to contain liquid away from the measurement chamber.Type: ApplicationFiled: December 10, 2021Publication date: June 15, 2023Applicant: GE Precision Healthcare LLCInventor: Mika Harri Juhani Hietala

Patent number: 11448640Abstract: A gas analyzer for measuring a respiratory gas component includes an emitter that transmits infrared (IR) radiation through a measurement chamber containing respiration gas, and at least one IR detector configured to receive at least a portion of the IR radiation transmitted through the measurement chamber and to generate radiation measurement data based on the received IR radiation. A light source is configured to emit light onto a color indicator, wherein the color indicator is one of a predefined set of colors. A color detector is configured to detect light reflected by a color indicator so as to identify color information. The controllers configured to determine a respiratory gas component concentration within the measurement chamber based on the color information and the radiation measurement data.Type: GrantFiled: October 15, 2019Date of Patent: September 20, 2022Assignee: GE Precision Healthcare LLCInventor: Mika Harri Juhani Hietala

Patent number: 11439785Abstract: Various methods and systems are provided for removing liquid from a sample containing both liquid component and gaseous component. In particular, the liquid component may be separated from the sample by flowing the gaseous component of the sample from a lower chamber to an upper chamber through a membrane. The liquid portion of the sample may be drain from the lower chamber via a drainage channel within the bottom wall of the lower chamber. The liquid portion of the sample flows horizontally outward in the drainage channel through capillary action induced by a capillary part positioned within the drainage channel.Type: GrantFiled: December 28, 2018Date of Patent: September 13, 2022Assignee: General Electric CompanyInventors: Mika Harri Juhani Hietala, Asko Saarelainen, Jarmo Luusua

Patent number: 11366056Abstract: A gas analyzer for measuring a respiratory gas component includes an emitter that emits two different wavelengths of infrared (IR) radiation in to a measurement chamber containing a respiratory gas, wherein the two different wavelengths include a first IR wavelength and a second IR wavelength. The gas analyzer further includes a first IR detector, a second IR detector, and a beam splitter. The beam splitter is configured to receive the two different wavelengths of radiation emitted by the emitter and to split the two wavelengths of radiation so as to reflect the first IR wavelength to the first IR detector and reflect the second IR wavelength to the second IR detector.Type: GrantFiled: October 1, 2019Date of Patent: June 21, 2022Assignee: GE Precision Healthcare LLCInventor: Mika Harri Juhani Hietala
