Patent application number | Description | Published |
20080275337 | BREATHING DETECTION APPARATUS AND METHOD - A device is disclosed for remote monitoring of breathing movements of a patient, comprising a sender transmitting a microwave signal toward the patient, a receiver arranged to receive a signal reflected by the patient, and a processor. The processor mixes the received signal with the transmitted signal and with a signal in quadrature with the transmitted signal to determine a breathing frequency of the patient. In some embodiments, two signals at different frequencies are emitted toward the patient and processed in order to compensate for breathing patterns that are not uniquely resolvable at a single frequency. | 11-06-2008 |
20080312565 | Cardiopulmonary Resuscitation Sensor - The present invention provides a CPR sensor that includes a thin and substantially flat flexible substrate having one or more sensor arrays, a power source, an output interface and a processor or analog circuit, all of which are disposed on the substantially flat flexible substrate. The substrate can be any shape (e.g., rectangular, circular, a polygon, an irregular shape that is decorative) and made from a polymer, metal film or other suitable material. Note that the substrate can be rigid or semi-flexible instead of flexible. A protective layer may cover the sensor array, the power source, and the processor or analog circuit. Alternatively, a protective covering can be used to encapsulate the device. The one or more sensor arrays measure one or more of the following compressions characteristics: compression depth, compression force, compression frequency and compression acceleration. | 12-18-2008 |
20110313322 | LIQUID PRESSURE FORCE SENSOR - The invention provides a force sensor device for measuring force when applying compressions or simulating applying compressions to a chest area of a person during cardiopulmonary resuscitation (CPR). More specifically, the device has the shape of a flat pad or similar with a top side and a bottom side, for being placed on a chest area of a man or manikin or on any feasible surface or object, preferably with the top side of the device facing up. The device comprises a volume that is filled with a liquid, the device is sufficiently high and rigid to maintain a distance between the top and bottom sides of the device when normal CPR compressions are applied on the device, and the device comprises at least one pressure sensor arranged with fluid contact with the liquid volume and in operative contact with means for force measurement as a function of liquid pressure that varies according to applied pressure during CPR. | 12-22-2011 |
20120089055 | PATIENT TAPE FORCE PAD - A CPR device for aiding a user in the performance of chest compressions, which is adapted to be placed on the chest of a patient and has means for measuring the compression force applied. The device has an electrically conductive means ( | 04-12-2012 |
20120191014 | METHOD AND SYSTEM FOR MEASURING CHEST PARAMETERS, ESPECIALLY DURING CPR - This invention relates to a system for monitoring the position of a measuring unit when placed on a person, especially on the chest of a person, the system comprising a drive unit generating a magnetic field oscillating at a predetermined frequency adapted to be positioned on the opposite side of the person, e.g. chest to back dimensions, and the measuring unit being adapted to measure the magnetic field strength, the system including calculating means for calculating the distance between the measuring unit and the drive unit. | 07-26-2012 |
20120220887 | CPR MONITORING SYSTEM WITH ACTIVE BACKBOARD - The invention relates to a monitoring system for monitoring CPR performance and a reference unit for use in the system. The system comprises a measuring unit for positioning on the chest of a patient or manikin monitoring the movements applied to the chest, wherein the system also comprises a reference unit, the reference unit comprising sensors for measuring the movements thereof, wherein said units comprises means for wireless communication, one of the units comprising a signal analyzing means and a signal receiver coupled thereto for receiving said wireless communication, and the other unit comprising a signal transmitter for transmitting the measured signals to the signal receiver. | 08-30-2012 |
20130218055 | CPR MONITORING SYSTEM - The invention relates to a system for monitoring CPR performed on a manikin. The manikin comprising means for measuring at least one first parameter concerning a performed CPR, and a measuring unit for positioning on the chest of a manikin or patient during CPR comprising sensors for measuring at least one second parameter concerning a performed CPR. The system also comprising analyzing means for analyzing said first and second parameters measured during a chosen time period during a performed CPR on said manikin and evaluating the measured parameters. | 08-22-2013 |
20150174420 | METHOD AND APPARATUS FOR DETECTING A SHOCK APPLIED TO A PATIENT DURING CPR - Method and apparatus for detecting electric energy delivered to the heart of a body when performing defibrillation. The method comprises the steps of applying a defibrillator with electrodes placed on opposite sides of the heart; applying an apparatus on the body and between said electrodes for detecting and measuring electric and/or magnetic fields; performing defibrillation by delivering electric energy to the body; detecting electric energy running through the heart with said apparatus, and indicating electric energy applied to the heart. The apparatus for performing the method comprises detection and indications means for performing the method. | 06-25-2015 |
