Claims

1. AN APPARATUS FOR THE MEASUREMENT OF PHYSIOLOGIC FLUID PRESSURE EXISTING BEHIND AN ELASTIC BODY MEMBRANE COMPRISING, IN COMBINATION, A RIGID APERTURED ELASTIC BODY MEMBRANE DEPRESSOR ELEMENT PROVIDED WITH AN ELASTIC BODY MEMBRANE-DEPRESSING FACE HAVING A SURFACE GENERALLY CONFORMING TO THAT OF THE UNDEPRESSED FLESH TO WHICH SAID DEPRESSOR ELEMENT IS TO BE APPLIED, A RIGID PRESSURE-DEFLECTIBLE FOOT SLIDABLY MOUNTED FOR FREE MOVEMENT WITHIN THE APERTURE IN SAID DEPRESSOR ELEMENT BACK OF SAID ELASTIC BODY MEMBRANE-DEPRESSING FACE AND WITH THE FORWARD FACE OF SAID FOOT DISPOSED INWARDLY FROM THE CLOSEST POINT ON SAID ELASTIC BODY MEMBRANE-DEPRESSING FACE ADJACENT SAID FOOT A DISTANCE SUBSTANTIALLY EQUAL TO THE NON-VARIANT DISTANCE FLESH UNDERLYING SAID APERTURE INTRUDES INTO SAID APERTURE UNDER THE PRESSURE WITH WHICH SAID DEPRESSOR ELEMENT DEPRESSES SAID ELASTIC BODY MEMBRANE DURING SAID MEASUREMENT OF SAID PHYSIOLOGIC FLUID PRESSURE, AND MEANS MEASURING SAID PHYSIOLOGIC FLUID PRESSURE AS A FUNCTION OF THE DISPLACEMENT OF SAID FOOT WHEN SAID DEPRESSOR ELEMENT IS MADE TO DEPRESS SAID ELASTIC BODY MEMBRANE WITHOUT OCCLUSION OF PHYSIOLOGIC FLUID PASSAGE THEREPAST.
