Abstract:
A cardio-pulmonary resuscitation device for cardiac compression of a patient's heart through expansion of the esophagus adjacent to the heart and simultaneous inflation of the patient's lungs, the device comprising:an elongate esophageal insert having a distal tip and a proximal end, the insert having a length adapted for oral insertion of the tip to an esophageal inserted position wherein the tip is disposed within the esophagus posterior the heart; esophageal expansion means located on the distal tip of the esophageal insert for compressing the patient's heart between an anterior of the patient's expanded esophagus and a posterior of the patient's sternum by expanding the esophagus when in the inserted position and for releasably sealing the esophagus against aspiration of stomach contents and regurgitation; a tracheal tube disposed substantially parallel the esophageal insert and having an insert end and a protruding end, the tracheal tube having a length adapted for oral insertion together with the esophageal insert to a tracheal inserted position wherein the insert end of the tracheal tube is disposed within the trachea, wherein the insert end includes pneumatic sealing means for releasably sealing the trachea about the tracheal tube; and control means in communication with the esophageal expansion means and with the tracheal tube, for selectively expanding and contracting the esophageal expansion means and simultaneously inflating and deflating the lungs of the patient via the tracheal tube sealed within the trachea of the patient.
