Chest mounted cardio pulmonary resuscitation device and system

Abstract

The Chest-positioner/pad Cardio Pulmonary Resuscitation System (CCPRS) provides improved resuscitation during one-person or two-person CPR. The simple, compact, portable and cost-effective system provides for manual, mechanical or electrical driven external chest compressions via a socket connection to a chest-positioner/pad unit. The chest-positioner/pad unit provides greater control of compression positioning providing adequate and reproducible chest compressions while preventing rib fractures and damage to vital internal organs. A module gives providers feedback to enable a provider to apply an appropriate compressive force in an appropriate direction, recurringly under emergency conditions. The present invention also provides improved blood circulation, oxygenation and gas exchange by expanding the chest past its normal relaxation point during diastole. Providers are able to administer adequate CPR for longer periods of time with reduced or minimal effort while improving survivability of cardiac arrest victims.

What is claimed is:  
     
         1 . An apparatus for assisting in the application of CPR to a thorax of a body, comprising: 
 a means to protect the thorax mounted on the thorax including a means to stabilize a means for applying compressions;    a means for determining a stroke rate connected to the stabilizing means;    a means for determining a compression force connected to the stabilizing means;    a means for determining whether a tilt condition exists in the application of the compression force connected to the stabilizing means; and    wherein the means for applying compressions is attached to the means for determining a compression force.    
     
     
         2 . The apparatus according to  claim 1  wherein said means to protect the thorax comprises a chest positioner/pad.  
     
     
         3 . The apparatus according to  claim 1  wherein said stabilizing means is a socket having a base and four sidewalls.  
     
     
         4 . The apparatus according to  claim 1  further including a means for maintaining said means to protect the thorax at a position upon which it is mounted on the thorax.  
     
     
         5 . The apparatus according to  claim 1  wherein the means for applying compressions is a rounded grip.  
     
     
         6 . The apparatus according to  claim 1  wherein the means for determining a compression force includes a pressure sensor which contacts a plate having a plurality of legs wherein the legs contact the stabilizing means.  
     
     
         7 . The apparatus according to  claim 1  wherein said means for determining whether a tilt condition exists includes a plurality of microswitches which contact a plurality of edges on a plate having a plurality of legs wherein the legs contact the stabilizing means.  
     
     
         8 . The apparatus according to  claim 1  further including a means to expand the chest beyond a normal diastole relaxation position.  
     
     
         9 . The apparatus according to  claim 1  further including a means for applying an abdomen compression.  
     
     
         10 . An apparatus for assisting in the application of CPR to a thorax of a body, comprising: 
 a means to protect the thorax mounted on the thorax including a means to stabilize a means for applying compressions;    the means for applying compressions including a means for maintaining a compression force at a preferred stroke rate connected to the stabilizing means;    a dorsal/back strap connected around the thorax and to the means for applying compressions; and    a means to expand the chest beyond a normal diastole relaxation position.    
     
     
         11 . The apparatus according to  claim 10  wherein said means to protect the thorax comprises a chest positioner/pad.  
     
     
         12 . The apparatus according to  claim 10  wherein said stabilizing means is a socket having a base and four sidewalls.  
     
     
         13 . The apparatus according to  claim 10  wherein said means to expand the chest comprises a recoil spring connected to the means for applying compressions and connected to the dorsal/back strap.  
     
     
         14 . The apparatus according to  claim 10  further including a means for applying abdomen compression to an abdomen of the body.  
     
     
         15 . The apparatus according to  claim 10  further including a connector attached between the means for applying compressions and the dorsal/back strap wherein the connector includes a means for indicating a tension of the dorsal/back strap.  
     
     
         16 . The apparatus according to  claim 10  wherein the means for applying compressions comprises a motor driven compression device.  
     
     
         17 . The apparatus according to  claim 10  wherein the means for applying compressions comprises a barehand driven augmentation device.  
     
     
         18 . An improved method for applying CPR to a thorax of a body by applying a pad to a chest of the body, applying a manual compression force on the chest, and monitoring a compression force which is applied, comprising: 
 sensing a direction in a which a compression force is applied;    determining whether the sensed direction and the compression force violate a tilt condition; and    communicating the existence of the tilt condition to a person interested in applying CPR.
