20160143804 | CPR CHEST COMPRESSION MACHINE WITH CAMERA - A CPR chest compression machine includes a retention structure configured to retain a patient's body, and a compression mechanism configured to perform automatically CPR compressions to the patient's chest. The CPR machine also includes a camera coupled to the retention structure or to the compression mechanism. The camera has a field of view that spans at least a certain portion of the patient's body, and is configured to acquire an image of what is spanned by its field of view. The image may be stored in a memory, displayed, transmitted, analyzed to diagnose the patient, detect shifting of the patient within the CPR machine, etc. | 05-26-2016 |
20160143805 | CPR ASSISTANCE SYSTEM AND CPR MONITORING METHOD - A CPR assistance system comprises a sensor for making a physiological measurement to generate a sensor signal which conveys information concerning the point in time at which venous return is completed. Time points are then determined at which CPR compression cycles should be administered, and output information is provided relating to the determined time points. The output information may be visual or audible advice to a person giving CPR or it may be control information for controlling an automated CPR system. | 05-26-2016 |
20160184180 | CARDIOPULMONARY RESUSCITATION SUPPORT DEVICE - A cardiopulmonary resuscitation support device including: a pressure sensing part configured to overlap a chest and including a flexible dielectric layer formed of an elastomer, and a flexible first and second electrodes formed of a conductive elastomer overlapped on two surfaces of the dielectric layer; a detection part provided at a facing part of the two electrodes to detect changes in electrostatic capacity; a power supply device to apply measurement voltage and a detection member to obtain the electrostatic capacity detected by the detection part connected to the electrodes; a processing member to calculate at least one piece of evaluation information among a number of compressions, a number of compressions per unit time, a pressing depth during compression, a pressing depth during release, and a ratio of a compression time, based on a detection value from the detection member. | 06-30-2016 |

20220133587 | ADJUSTABLE BACK PLATE FOR MECHANICAL COMPRESSION DEVICE - Examples of the disclosure are directed to adjustable back plates or backboards for a mechanical compression device to accommodate different patient sizes and/or for ease of storage. Examples of the disclosure includes back plates that can be folded, pieced together, or otherwise have a variable distance between connectors that attach to legs of a chest compression device. Examples also include back plates which may have two sides, such as an adult patient side and a pediatric patient side, to accommodate different patient sizes. | 05-05-2022 |
