Abstract

A hollow rubber chamber filled with a fluid and equipped with a pressure gauge, the chamber being designed for placement over the sternum of a heart victim while giving external cardiac compression as a means for restoring heart action. As force is applied to the sternum through the hollow rubber chamber, the gauge registers the amount of pressure applied and thus aids in the optimum administration of the Cardio Pulmonary Resuscitation (CPR) procedure.

Claims

1. A breastplate compression aid for placement on the chest of a human victim over the victim'"'"'s sternum comprising:

an elongated compressible hollow member having approximately the length and shape of the sternum of an adult person,

said member defining a closed hollow chamber along its length having substantially an oval cross-sectional configuration,

a pressure gauge attached at one end of said member in fluid pressure contact with the hollow interior of said member,

the other end of said member being provided with means for indicating the position of the base of the victim'"'"'s sternum,

fluid means for filling said chamber,

whereby when said aid is placed on the body of a victim over the sternum with the longer dimension of said chamber co-planar with the surface of the victim'"'"'s body and pressure is applied to said member, it will be transferred to the victim'"'"'s sternum and a representation thereof indicated on said gauge.

2. The breastplate compression aid set forth in claim 1 wherein:

said means for indicating the position of the base of said victim'"'"'s sternum comprises a tab extending axially out of said member along its longitudinal axis.

3. The breastplate compression aid set forth in claim 2 wherein:

said tab resembles the xiphoid at the base of a human sternum.

4. The breastplate compression aid set forth in claim 1 wherein:

said member and tab are formed of a flexible synthetic material.

5. The breastplate compression aid set forth in claim 1 wherein:

said member and tab are formed of flexible rubber.

6. The breastplate compression aid set forth in claim 1 wherein:

said pressure gauge comprises a Bourdon gauge.

7. The breastplate compression aid set forth in claim 1 wherein:

said fluid means comprises a non-corrosive liquid.

8. The breastplate compression aid set forth in claim 2 wherein:

said gauge and tab are axially aligned with the longitudinal axis of said member and indicia on each are co-planar arranged.
