CARDIOPULMONARY RESUSCITATION SUPPORT DEVICE

摘要

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.

1. A cardiopulmonary resuscitation support device for assisting with cardiopulmonary resuscitation using chest compressions, comprising:
a pressure sensing part configured to be overlapped on a chest, the pressure sensing part including a flexible dielectric layer formed of an elastomer, and a flexible first electrode and a flexible second electrode formed of a conductive elastomer and overlapped on respective two surfaces of the dielectric layer; at least one detection part provided at a facing part of the first electrode and the second electrode in the pressure sensing part so as to detect changes in electrostatic capacity that accompany changes in a facing distance between the first electrode and the second electrode; a power supply device to apply measurement voltage connected to the first electrode and the second electrode; a detection member to obtain the electrostatic capacity detected by the detection part, the detection member being connected to the first electrode and the second electrode; and a processing member to calculate at least one piece of evaluation information from among a number of chest compressions, a number of chest compressions per unit of time, a chest pressing depth during chest compression, a chest pressing depth during chest release, and a ratio of a compression time of pressing the chest and a return time of not pressing the chest, based on a detection value of the electrostatic capacity detected by the detection part obtained by the detection member.
