Publication number: 20230355468Abstract: A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.Type: ApplicationFiled: July 13, 2023Publication date: November 9, 2023Applicant: PHYSIO-CONTROL, INC.Inventors: Anders Nilsson, Jonas Lagerstrom, Bo Mellberg, Anders Jeppsson, Marcus Ehrstedt, Bjarne Madsen Hardig, Fredrik Arnwald, Erik von Schenck, Paul Rasmusson, Sara Lindroth, Fred Chapman, Ryan Landon, Mitchell A.

Publication number: 20220354738Abstract: Techniques and devices for extending a piston and/or compression unit, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, some aspects, the piston includes sleeves which can move relative to each other to extend the piston. In additional aspects, the compression mechanism may also extend downward toward the patient. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.Type: ApplicationFiled: May 4, 2022Publication date: November 10, 2022Applicant: PHYSIO-CONTROL, INC.Inventors: Anders Jeppsson, Wiktor Kocula, Jonas Lagerstrom, Per Axelsson, Marcus Ehrstedt, Anders Nilsson, Tobias Svahn, Lars Anders Jörgen Segerstein
