Publication number: 20230078384Abstract: A method for a thawing device configured to thaw/heat a blood product comprised in a container, the method comprising the steps of performing a massaging motion, by a first actuator, on one or more areas of an outer surface of the container, obtaining measurements, from a reflectance sensor coupled to an antenna, the measurements at least being indicative of phase of received radio frequency, RF, waves having a second frequency and being reflected off the container, determining a third frequency, wherein the third frequency is determined by a predetermined relation dependent on the second frequency and the obtained measurements, controlling a transmitter, communicatively coupled to the antenna, to emit RF waves, using the obtained measurements, wherein the emitted RF waves are emitted at a third frequency and are directed by the antenna to propagate towards the container, wherein the third frequency is in the range of 10 to 900 MHz.Type: ApplicationFiled: January 20, 2021Publication date: March 16, 2023Inventors: Mattias TULLBERG, Joachim SÄLLVIN, Andreas SVENSSON, Sven SUNDIN

Patent number: 9474468Abstract: In a method for positioning linear array of electrodes (LAE) mounted on distal end section of elongated flexible member in patient's respiratory airways (PRA) at level of diaphragm, a length of the member pre-determined to position LEA at the level of the diaphragm is inserted through PRA. Signals representative of an electrical activity of the diaphragm (EAdi) are detected through LAE, presence/absence of ECG signal components is detected in EAdi signals, and position of LAE in PRA is detected in response to presence/absence of ECG signal components in EAdi signals. Lower esophageal sphincter activity may be detected in EAdi signals, and position of LAE in PRA determined in response to the detected lower esophageal sphincter. End-expiratory occlusion of PRA may be performed to verify that the electrical activity of the diaphragm coincides with a negative deflection of PRA pressure again in view of determining adequate positioning of LAE.Type: GrantFiled: June 18, 2013Date of Patent: October 25, 2016Assignee: MAQUET CRITICAL CARE ABInventors: Christer Sinderby, Jennifer Beck, Frederik Jalde, Joachim Sallvin

Patent number: 7086098Abstract: A mechanical breathing aid for providing a regulated supply of a breathing gas has an expiratory pressure regulator for regulating gas pressure within an expiration gas flow path dependent on an input regulatory signal and an expiratory pressure sensor disposed to sense an actual gas pressure within the expiration gas flow path and to provide an output signal indicative thereof. A control unit is operably coupled to the expiratory pressure regulator and to the expiratory pressure sensor for calculating a target pressure as a function of time dependent on a value of compliance calculated from measurements of pressure and flow of provided breathing gas made during an inspiration phase, and for generating the regulatory signal dependent on a magnitude of the difference between the target pressure and the actual pressure.Type: GrantFiled: March 5, 2002Date of Patent: August 8, 2006Assignee: Maquet Critical Care ABInventor: Joachim Sallvin
