A device for the determination of at least one compression parameter during the administration of cardiopulmonary resuscitation (CPR) on a patient. The device includes a compression unit adapted to move in accordance with the chest of a patient and a surface unit adapted to move in accordance with a surface supporting the patient. The compression unit has one of a signal component and reference component, the surface unit has the other of the signal component and the reference component. The device also includes a processor configured to determine a relative measurement between the compression unit and the surface unit using data derived from the signal component and the reference component. The processor is further configured to determine the at least one compression parameter based on the relative measurement. The determined at least one compression parameter takes into account any motion and/or displacement of the surface.

Measurement of a compression parameter for CPR on a surface

A device for the determination of at least one compression parameter during administration of cardiopulmonary resuscitation (CPR) on a patient comprising: a field generator, a field detector, and a processor. Position information and the compression parameter are determined from the field detected by the field detector. One of the field generator and the field detector is a position sensor and the other is a reference sensor.

CPR assist device for measuring compression parameters during cardiopulmonary resuscitation

Disclosed systems and methods determine chest compression parameter(s) for a patient receiving chest compressions during cardiopulmonary resuscitation (CPR). The systems and methods determine the chest compression parameter(s), such as chest compression depth, using a reference sensor and multiple positions sensors.

System and method for determining depth of chest compressions

Embodiments of the present invention are related to a method and device for the determination and calculation of the depth of chest compressions during the administration of cardiopulmonary resuscitation (CPR). Embodiments use an optical sensor to monitor the distance that a victim's chest is displaced during each compression throughout the administration of CPR. The optical sensor is most commonly an image sensor such as a CMOS or CCD sensor, and more specifically a CMOS image sensor capable of three-dimensional imaging based on the time-of-flight principle. An infrared emitter may illuminate the victim's body and any visible piece of ground beside the victim. As the infrared light interacts with any surfaces it encounters, it is reflected and returns to the image sensor where the time of flight of the infrared light is calculated for every pixel in the image sensor. The distance data is used to gauge the effective displacement of the victim's chest. The optical sensors can be used to visualize the size of a patient and immediately gauge the body type and instruct the user accordingly. Furthermore, optical measurement techniques can be used to accurately measure chest rise during artificial respiration and ensure that proper ventilation is being administered in between compressions. In addition, optical measurements of the chest of the victim and the hands of the rescuer can be used to help ensure that the rescuer has positioned his or her hands in the anatomically correct location for effective CPR.

Optical techniques for the measurement of chest compression depth and other parameters during CPR

A wearable cardiopulmonary resuscitation assist device or system including: a wearable article to be worn by a cardiopulmonary resuscitation performer or a patient, for assisting administration of cardiopulmonary resuscitation by the performer; at least one sensor for measuring at least one parameter to assist in cardiopulmonary resuscitation; at least one feedback component for conveying feedback information based on the parameter to the performer for assisting the performer in performing cardiopulmonary resuscitation; and a processing unit, the processing unit being configured to receive the at least one parameter from the at least one sensor and to send information based on the parameter to the at least one feedback component. Also a method for training or improving cardiopulmonary resuscitation procedures using the device.

Wearable CPR assist, training and testing device

Systems and methods for determining depth of compressions of a chest of a patient receiving chest compressions. A field detector is used having at least two coils at a fixed distance from each other.

Embodiments of the present concept are directed to medical devices for use by a rescuer who is caring for a patient and includes a bottom device for use with a top device to measure the depth of Cardio Pulmonary Resuscitation (CPR) chest compressions delivered to the chest of a patient. The top device is intended for placement on the chest of the patient and has a top mechanism that is moveable up and down as the chest compressions are delivered to the patient. The bottom device includes a generally elongate member having a handle at one end and a bottom mechanism near the opposite end. The elongate member is structured to be placed under the patient during delivery of CPR. The top mechanism and the bottom mechanism cooperate to generate a value for a net depth of the compressions of the patient chest with reference to each other.

Reference sensor for CPR feedback device

Chest pad for CPR feedback device

A support device for assisting a wearer in the administration of cardiopulmonary resuscitation (CPR), the device comprising: a wearable support for strengthening at least one of the wearer's wrist, hand or forearm, the wearable support being adapted to circumscribe a majority of the circumference of the at least one of the wearer's wrist, hand or forearm; wherein the wearable support is adapted to be in close contact with the at least one of the wearer's wrist, hand or forearm, to provide support to the wearer through compression of the at least one of the wearer's wrist, hand or forearm.

Support device for administration of CPR

A device for the determination of at least one compression parameter during the administration of cardiopulmonary resuscitation (CPR) on a patient. The device includes a compression unit adapted to move in accordance with the chest of the patient and a surface unit adapted to move in accordance with a surface supporting the patient. The compression unit has one of a signal component and a reference component, the surface unit has the other of the signal component and the reference component. The device also includes a processor configured to determine a relative measurement between the compression unit and the surface unit using data derived from the signal component and the reference component. The processor is further configured to determine the at least one compression parameter based on the relative measurement. The determined at least one compression parameter takes into account any motion and/or displacement of the surface.

Embodiments of the invention provide a facility for measuring critical CPR parameters during first aid training. Specifically, the device provides a manikin housing for the insertion of a consumer electronic device such as phone, music player, personal assistant, game controller or other device with necessary sensory for the measurement of the CPR parameters. Tactile buttons, touch sensitive displays and embedded accelerometers in these devices may be used to accurately measure CPR parameters. In certain embodiments, parameters may be measured using a game console controller and the feedback may be displayed on a television in the form of a video game.
