Chest Compression Device with Electro-Stimulation
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.
