Publication number: 20240065934Abstract: In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system can include a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. The compression mechanism can during a CPR session retreat a distance away from the patient's chest whereby the patient's chest can expand without active decompression of the patient's chest beyond the chest's natural resting position.Type: ApplicationFiled: November 8, 2023Publication date: February 29, 2024Applicant: PHYSIO-CONTROL, INC.Inventors: Erik von Schenck, Anders Nilsson, Sara Lindroth, Jonas Lagerström, Bjarne Madsen Härdig, Thomas Falk

Publication number: 20220280379Abstract: Embodiments of a Cardio-Pulmonary Resuscitation (“CPR”) device are disclosed. A CPR device can include a compression mechanism configured to perform successive CPR compressions on a chest of a patient, the compression mechanism including a support portion configured to be placed underneath a patient, a piston, and a contact surface configured to make contact with the chest at a first orientation with respect to the support portion; and a controller communicatively coupled with the compression mechanism. The controller can be configured to receive at least one input and determine whether the first orientation of the contact surface should be adjusted based on the at least one input. The controller can further, responsive to a determination that the first orientation of the contact surface should be adjusted, cause the contact surface to move so that the contact surface makes contact with the chest at a second orientation with respect to the support portion.Type: ApplicationFiled: May 25, 2022Publication date: September 8, 2022Applicant: PHYSIO-CONTROL, INC.Inventors: Bjarne Madsen Härdig, Marcus Ehrstedt

Patent number: 10849820Abstract: A cardiopulmonary resuscitation (“CPR”) device that includes a chest compression mechanism, a support structure, and a plurality of inflatable support pads. The chest compression mechanism is configured to deliver CPR chest compressions to a patient. The support structure includes a base member configured to be placed underneath a patient, and a leg configured to support the chest compression mechanism at a distance from the base member. The plurality of inflatable support pads are configured to provide lateral support to a patient's chest during use of the CPR device. Each support pad within the plurality of support pads includes a holder configured to retain and at least partially surround the adjacent support pad.Type: GrantFiled: October 23, 2018Date of Patent: December 1, 2020Assignee: PHYSIO-CONTROL, INC.Inventors: Erik von Schenck, Anders Nilsson, Marcus Ehrstedt, Anders Jeppsson, Bjarne Madsen Härdig

Patent number: 10792215Abstract: A mechanism attached to a mechanical CPR device can be automatically attached to the patient's torso. The mechanical CPR device can extend the mechanism to a first position at which the mechanism comes into contact with the patient's torso. The mechanism can be further extended until a first threshold is reached. The mechanism can be retracted to the first position. The mechanism can be further retracted from the first position until a second threshold is exceeded. The mechanism can then be extended to a second point at which the second threshold is no longer exceeded. The mechanism may comprise a suction cup or sticker plate, and may be attached to an end of a piston of the mechanical CPR device.Type: GrantFiled: July 12, 2017Date of Patent: October 6, 2020Assignee: PHYSIO-CONTROL, INC.Inventors: Lars Anders Nilsson, Bjarne Madsen Härdig

Publication number: 20190175443Abstract: The disclosed CPR devices, systems, and methods adjust a compression depth of a compression mechanism to account for chest collapse of the patient receiving CPR. Compression depth can be adjusted up to a maximum depth in some examples. The compression depth can also be adjusted linearly or non-linearly as the zero point or starting position of the patient's chest changes due to chest collapse. Other factors can also be used to adjust the compression depth such as patient parameters that can be observed by a rescuer or sensed by sensors wirelessly connected to or integrated into the system. CPR devices that include active decompression can also use the disclosed techniques for adjusting the chest compression depth as the patient's chest collapses.Type: ApplicationFiled: July 28, 2017Publication date: June 13, 2019Inventors: Bjarne Madsen HÄRDIG, Karl Fredrik MAURITZ ARNWALD, Anders NILSSON, Erik VON SCHENCK, Sara LINDROTH
