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.

1 . A device for resuscitating a patient comprising:
 a chest compression device capable of repeatedly compressing the chest of the patient and causing or allowing the chest to expand;   an electro-stimulation system including defibrillating electrodes connecting the electro-stimulation system to the patient and an electrical generator;   a controller for coordinating and controlling the chest compression device and the electro-stimulation system to apply electro-stimulation to the defibrillating electrodes after a period of static compression when the chest is allowed to expand.   
   
   
       2 . The device of  claim 1  wherein the controller comprises:
 a controller for coordinating and controlling the chest compression device and the electro-stimulation system to apply electro-stimulation to the defibrillating electrodes immediately following a compression cycle when the chest is allowed to expand.   
   
   
       3 . The device of  claim 1 , further comprising:
 at least one feedback device operably connected to the patient, wherein said feedback device comprises   a sensor,   an electrical signal generator and   a signal transmitter, and said feedback device senses at least one biological parameter of the patient, generates a corresponding electrical signal, and transmits the corresponding signal to the controller, and wherein the controller adjusts the operation of the electro-stimulation system on the basis of the sensed feedback.   
   
   
       4 . The device of  claim 2 , wherein said feedback device further comprises:
 a protection circuit for protecting the feedback device from electrical energy applied by the electro-stimulation system.   
   
   
       5 . The device of  claim 1 , wherein the controller is capable of receiving a stop signal command to cease chest compression and electro-stimulation, and said controller checks for the stop signal command before each cycle of chest compression and before each application of electro-stimulation.
