A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.

Devices and methods for CPR chest compression with active decompression.

An automated chest compression device for performing CPR, with distance sensors disposed on a compressing mechanism and on a structure fixed relative to the CPR patient, for determining inferior/superior movement of the compressing mechanism over the course of multiple compressions.

The invention relates to an anteroposterior thoracic restriction device comprising holding means intended to surround a patient's chest, a compressible fluid bag, intended to be held against the patient's sternum by said holding means, and reversible bilateral tightening means, arranged on either side of the fluid bag and capable of reversibly tightening the holding means around the patient's chest.

The invention relates to a device for controlled cardiopulmonary resuscitation, which allows the user to reanimate a human body quickly and simply during a cardiac arrest. The geometric dimensions of the claimed device are comparatively small and lie between approximately 10 and 25 cm in diameter and approximately 6 and 12 cm in height. During use, a force K is exerted onto a first force transmission means, a clearly audible signal being generated when a maximum adjustable force exertion Kmax is reached. Said clearly audible signal is primarily generated by the interaction of oscillatory elements of said device.

A chest compression device for cardiopulmonary resuscitation comprises a support structure 2 for placement about a patient's chest and for holding a chest compressor 6 above a patient's sternum; a chest compressor 6 mounted on the support structure 2; and lateral chest supports 14 attached to the support structure 2 at points laterally either side of the chest when the device is in use, such that the lateral chest supports 14 will apply lateral pressure to the sides of the chest synchronized with a chest compression by the chest compressor 6.

The present disclosure provides a cardio pulmonary resuscitation (CPR) apparatus for performing a chest compression on a patient supported by a support. The apparatus includes an actuator operatively coupled to a compression mechanism for actuating the compression mechanism to perform the chest compression. The compression mechanism is securable to the support and is configured to repeatedly perform chest compressions on the patient in an operating space, the operating space being the space in which the compression mechanism operates. The actuator is positioned outside of the operating space. The present disclosure further provides a monitoring system having the CPR apparatus and a feedback system coupled to the CPR apparatus.

An automated resuscitation system is provided, which can improve the outcome of patients suffering ventricular fibrillation or the ventricular tachycardia variants of cardiac arrest. This outcome can be achieved by a device that integrates automatic mechanical or pneumatic capability with electrical countershock capability such that the probability of defibrillation or cardioversion with return of spontaneous circulation is increased.

A system for performing an active compression decompression (ACD) treatment on a patient includes a platform for placement under a patient, a chest compression actuator that may include a belt configured to extend over a thorax of the patient, an upward force actuator, a coupling mechanism for coupling the upward force actuator to the thorax of the patient to transfer a decompressing force from the upward force actuator to the thorax of the patient, and a motor that is coupled to the belt, the motor configured to cause the belt to tighten about the thorax of the patient and exert a compressing force on the thorax of the patient; and cause the belt to loosen about the thorax of the patient and allow the upward force actuator to cause decompression of the patient.
