BIOMETRIC PARAMETER DATA EXTRACTION FROM A PATIENT SURFACE BY AIR PRESSURE SENSING
First Claim
1. A method for obtaining patient biometric parameter data from a patient support surface comprising at least one air pressure bladder inflated by air pressure through an air supply line from an air pump reservoir controlled by a bladder air controller receiving an air pressure signal from a pressure sensor in the air supply line, comprising the step of:
- signal processing a variation of the air pressure signal from the pressure sensor to extract the patient biometric parameter data.

Abstract
In a method or system for obtaining patient biometric parameter data from a patient support surface comprising at least one air pressure bladder inflated by air pressure through an air supply line from an air pump reservoir controlled by a bladder air controller receiving an air pressure signal from a pressure sensor in the air supply line, signal processing a variation of the air pressure signal from the pressure sensor to extract the patient biometric parameter data.

15. A method for obtaining patient biometric parameter data from a pre-existing patient support surface comprising at least one air pressure bladder inflated by air pressure through an air supply line from a pre-existing air pump reservoir controlled by a bladder air controller receiving an air pressure signal from a pressure sensor in the air supply line, comprising the step of:
-
connecting a signal processor to receive said air pressure signal from the pressure sensor; and signal processing a variation of the air pressure signal from the pressure sensor by use of the signal processor to extract the patient biometric parameter data.
