Problems solved by technology

The settings of the light source may change over time, causing drastic color changes on the measurement area (i.e., region of interest) of the subject (specifically, the biological face) and making extraction of vital signs extremely difficult, in some cases even impossible

Embodiment Construction

[0040] figure 1 A first embodiment of a device 1a according to the invention for obtaining vital sign information of a living being 2 such as a patient in a hospital, an elderly person being monitored in bed at home or a person exercising in a fitness club is shown. The device 1a comprises a detection unit 3 for receiving light 4 in at least one wavelength interval reflected from at least a region of interest of a living being 2 and for generating an input signal 5 from the received light 4 . For example, the detection unit 3 is configured to record the spatial-temporal variation of the received light 4, and is preferably an imaging unit for taking images, such as the living being 2 or at least a region of interest (ROI) of the living being 2 substantially continuously or periodically 20 images from the camera.

[0041] The device 1a also comprises a processing unit 6 for processing an input signal 5 and deriving vital sign information 7 of said living being 2 from said input...

Abstract

The present invention relates to a device (1) and method for obtaining vital sign information of a living being (2). The proposed device (1) comprises a detection unit (3) for receiving light (4) in at least one wavelength interval reflected from at least a region of interest (20) of a living being (2) and for generating an input signal (5) from the received light (4), a processing unit (6) for processing the input signal (5) and deriving vital sign information (7) of said living being from said input signal (5) by use of remote photoplethysmography, and an illumination unit (8) for illuminating at least said region of interest (20) during illumination intervals with light, wherein said light during said illumination intervals is optimized for deriving vital sign information from an input signal generated by use of remote photoplethysmography from received light reflected from said region of interest.

Description

technical field [0001] The present invention relates to a device and a corresponding method for obtaining vital sign information of a living being. Background technique [0002] Unobtrusive vital sign monitoring using cameras or remote PPG (photoplethysmography) has been proven and found to be relevant for patient monitoring. Remote photoplethysmographic imaging is described, for example, in the article "Remote plethysmographic imaging using ambient light" by Wim Verkruysse, Lars O. Svaasand and J. Stuart Nelson (Optics Express, Volume 16, Number 26, December 2008). The technique is based on the principle that temporal changes in blood volume in the skin lead to changes in the skin's absorption of light. Such changes can be recorded by a camera taking an image of an area of ​​skin (such as the face) and processed to calculate an average value of pixels over a manually selected area (typically a part of the cheek in this system). By looking at the periodic variation of this...
