WEARABLE PAIN MONITOR USING ACCELEROMETRY
First Claim
1. Device for monitoring pain of a user, comprising:
- a receiving unit for receiving an accelerometer signal from an accelerometer sensor to be worn in use by the user, wherein the accelerometer signal comprises components of a pulse signal and components of a respiration signal; and
a processing unit which is configured to;
derive the pulse signal and the respiration signal from the accelerometer signal;
adapt the pulse signal based on the respiration signal in order to obtain a corrected pulse signal; and
derive a pain descriptor based on the corrected pulse signal.

Abstract
A device and method for monitoring pain of a user (50) are presented. The device (10) comprises a receiving unit (12) for receiving an accelerometer signal (38) from an accelerometer sensor (30) worn by the user (50), wherein the accelerometer signal (38) comprises components of a pulse signal (20) and a respiration signal (22); and a processing unit (14) configured to: derive the pulse signal (20) and the respiration signal (22) from the accelerometer signal (38); adapt the pulse signal (20) based on the respiration signal (22) in order to obtain a corrected pulse signal (40); and derive a pain descriptor based on the corrected pulse signal (40).
