CONTACTLESS RESPIRATION MONITORING OF A PATIENT AND OPTICAL SENSOR FOR A PHOTOPLETHYSMOGRAPHY MEASUREMENT
First Claim
1. An optical sensor for a photoplethysmography measurement, comprisinga light unit with a light emitter for emitting light into tissue of a patient and/or a light detector for detecting a part of the emitted light after interaction with the tissue, whereinthe light unit is embedded in an elastic material.

Abstract
The invention also relates to an optical sensor for a photoplethysmography measurement, comprising a light unit 1 with a light emitter 2 for emitting light into tissue of a patient 8 and/or a light detector 3 for detecting a part of the emitted light after interaction with the tissue, wherein the light unit is embedded in an elastic material 4. The invention further relates to a device for contactless respiration monitoring of a patient 8, comprising: a distance sensor for consecutively detecting the temporal distance variations relative to the patient'"'"'s chest 12, preferably based on electromagnetic waves; and a calculating unit for determining the breathing activity based on the detected temporal distance variations. The invention is especially useful for providing a reliable and easy to use possibility for simultaneously monitoring respiration action, blood pressure and heart rate with a handheld device which can be used for spot-checking the vital parameters of patients in hospitals.
