摘要:
A system for resuscitation of a heart attack victim. The system includes CPR device which compresses the victim's chest, a defibrillator which may be used to defibrillate the patient, and an identification system for identifying the person operating the system. Depending on the identity of the operator, the system permits varying degrees of access to components and enablement of the functions of the various subsystems
摘要:
A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.
摘要:
A lightweight electro-mechanical chest compression device. The device (2) is provided with a motor (79), a brake (82), a drive spool (42), a control system (83, 84, 85), and a metal channel beam (41) to brace the device and guide a compression belt (3). The belt (3) is provided in a belt cartridge (5) that attaches to the channel beam (41). In use, the belt (3) is secured around the patient (1) and to the drive spool (42). The motor (79) tightens the belt (3) by turning the drive spool (42). The electro-mechanical chest compression device (2) weights less than 30 pounds when fully assembled with its power source (21).
摘要:
A modular CPR assist device comprises a belt, a belt tensioning means operably connected to the belt, a motor operably connected to the belt tensioning, said motor capable of operating the belt tensioning means repeatedly to cause the belt to tighten about the chest of the patient and loosen about the chest of the patient, a controller for controlling operation of the motor, wherein said controller is programmed to operate the motor and the belt tensioning means to cause repeated cycles of tightening of the belt about the chest of the patient and loosening of the belt about the chest of the patient, and an encoder operably connected to a component of the chest compression device, so that the encoder is capable of measuring the position of the belt, said encoder being capable of transmitting a belt position signal indicative of the position of the belt to the controller.
摘要:
The invention regards a resuscitation system which comprises chest compression devices (1) to repeatedly compress the chest of a patient and thereafter causing or allowing the chest to expand, power supply devices (20), and a signal processor (4) connected to the chest compression devices to control operation of the chest compression devices.
摘要:
A resuscitation device (1) for automatic compression of victim's chest using a compression belt (3) which exerts force evenly over the entire thoracic cavity. The belt (3) is constricted and relaxed through a motorized spool assembly (7) which repeatedly tightens the belt and relaxes the belt to provide repeated and rapid chest compression. An assembly includes various resuscitation devices including chest compression devices (2), defibrillation devices (39), and sensors (36) which initiate communications with emergency medical personnel automatically upon use of the device.
摘要:
A positioning device for use in apparatus for treating sudden cardiac arrest in a patient in supine position by providing chest compressions at the lower end of the sternum prevents the apparatus from moving in a caudal direction. The apparatus comprises a frame enclosing the patient at a sternal transversal plane and a pneumatic compression/decompression means mounted on the frame. The device comprises a flexible strap having a first end, a second end and a tensioning means disposed between the first and second ends. First and second end portions of the strap comprise means for attachment to the apparatus. The flexible strap has a mounted tensioned length sufficient to extend around the patient's neck. At least one of the end portions is releaseably attached.
摘要:
A compression belt cartridge (5) has a double-oar shaped belt (3) and a cover plate (44) through which the belt (3) is threaded. The cover plate (44) is provided with hooks (51, 52, 53,54) and snap latches (47, 48, 49, 50) that fit into a belt drive platform (4). The cover plate (44) is sized and dimensioned to fit within only selected platforms. The belt (3) attaches to the means for tightening (42) the belt (3) via a spline (66) attached to the belt (3). The means for tightening (42) a belt (3) then repetitively tightens the belt (3), thereby accomplishing chest compressions.
