Pressure measurement method
First Claim
1. A method of measuring the compression applied to a portion of a body by a resilient inflatable garment, comprising the steps of:
- inserting a flexible pressurizable member between the body portion and the garment to receive the compression applied by the garment; and
determining the pressure in said member due to the compression, said pressure being approximately equal to the compression applied to the body portion.

Abstract
A method of determining the pressure applied to a limb by an inflatable garment by placing a flexible pressurizable cuff between the garment and the limb to receive the compressive garment forces and then determining the pressure in the cuff due to those compressive forces alone. The cuff pressure component due to compression of the garment is determined by extrapolating from a plot of cuff pressure versus bias pressure. The bias pressure is required to obtain an accurate reading of cuff pressure and is eliminated as a component in determining the garment pressure by means of the extrapolation. A preferred transducer for converting cuff pressure to electrical signals employs a manometer tube extending between two plates of a capacitor.
