US 2020/0138387 A1 · Device for Patient Monitoring

Abstract

A movement detection device for detecting quantitatively the movement of a patient by capturing images of a deformable surface having an indicator associated therewith, the indicator being responsive to changes in a profile of the deformable surface. The captured images are analysed to derive a patient movement from the changes in the profile of the deformable surface. For example, the movement detection device of the invention can detect the sense (translational and/or rotational) and magnitude of the patient movement. This information may enable real time adjustment of the treatment signal or indeed provide a safety facility whereby should there be detection that the patent has moved or has moved beyond certain parameters, the device that is observing or treating the patent is switched off.

Dependent claims

A device for detecting patient movement whilst undergoing a medical process, the device comprising:

a deformable surface;
an indicator associated with the deformable surface, the indicator being responsive to changes in a profile of the deformable surface;
an imaging device arranged to capture images of the indicator;
and
a processor arranged to:
analyse the captured images to determine changes in the profile of the deformable surface,
derive a patient movement from the determined changes in the profile of the deformable surface, and
output information indicative of the derived patient movement,
wherein the derived patient movement comprises a type and magnitude of motion.
