Chest compression device with electro-stimulation

Abstract

A device for performing chest compressions for CPR in coordination with applying electro-stimulus for additional resuscitative actions such as electro-ventilation, electro-counterpulsion, and defibrillation. The device includes a chest compression mechanism, electrodes and power supply for electro-stimulus, and a control system for applying electro-stimulus in coordination with the action of the chest compression mechanism.

We claim:  
     
         1 . A device for resuscitating a patient, the patient having a chest, intercostal muscles, and a diaphragm, said device comprising: 
 a chest compression device for repeatedly compressing and decompressing the chest of the patient;    an electro-stimulation system comprising a pair of ventilation electrodes and an electrical generator, wherein the electrical generator generates a multiplicity of electrical signals and transmits the electrical signals to the pair of ventilation electrodes; and    a controller for operating the chest compression device and the electro-stimulation system, wherein the controller operates the electro-stimulation system when the chest compression device is decompressing the chest;    wherein the ventilation electrodes receives the electrical signals from the electrical generator and delivers the electrical signal to the diaphragm and the intercostal muscles to induce an inhalation.    
     
     
         2 . A device for resuscitating a patient, the patient having a chest, a heart, a diaphragm, intercostal muscles, and abdominal muscles, said device comprising: 
 a chest compression device for repeatedly compressing and decompressing the chest of the patient;    an electro-stimulation system comprising a plurality of electrodes and an electrical generator, the electrical generator generates a multiplicity of electrical signals and transmits the electrical signals to the plurality of electrodes; and    a controller for operating the chest compression device and the electro-stimulation system, said controller coordinates the operation of the chest compression device with the operation of the electro-stimulation system;    wherein the plurality of electrodes comprise a pair of ventilation electrodes, a pair of counterpulsion electrodes and a pair of defibrillation electrodes; and    wherein the pair of ventilation electrodes transmit at least one of the multiplicity of electrical signals from the electrical generator to stimulate respiration, wherein the pair of counterpulsion electrodes transmit at least one of the multiplicity of electrical signal from the electrical generator to stimulate the abdominal muscles, and wherein the pair of defibrillation electrodes transmit at least one of the multiplicity of electrical signals from the electrical generator to defibrillate the heart,    wherein the controller operates the ventilation electrodes, the counterpulsion electrodes, and the defibrillation electrodes when the chest compression device is decompressing the chest.    
     
     
         3 . A device for resuscitating a patient, the patient having a chest, a heart, a diaphragm, intercostal muscles, and abdominal muscles, said device comprising: 
 a chest compression device for repeatedly compressing and decompressing the chest of the patient;    an electro-stimulation system comprising a plurality of electrodes and an electrical generator, the electrical generator generates electrical signals and transmits the electrical signals to the plurality of electrodes; and    a controller for operating the chest compression device and the electro-stimulation system, said controller coordinates the operation of the chest compression device with the operation of the electro-stimulation system;    wherein the plurality of electrodes comprise a pair of ventilation electrodes, electrically connected to the generator, for transmitting the electrical signals to stimulate the diaphragm and intercostal muscles, a pair of counterpulsion electrodes, electrically connected to the generator, for transmitting the electrical signals to stimulate the abdominal muscles, a pair of defibrillation electrodes, electrically connected to the generator, for transmitting the electrical signals to defibrillate the heart,    wherein the controller operates the ventilation electrodes, the counterpulsion electrodes, and the defibrillation electrodes when the chest compression device is decompressing the chest.
