Device and method for vital sign measurement of a person
First Claim
1. A vital sign measurement device, the device comprising:
- presentation means for presenting a visual theme within an illumination area of a room to create an ambient healing environment (AHE) of illumination effects for a person located within the illumination area of the room, wherein the AHE comprises direct light from the illumination effects presented to the person and indirect light from reflections of the illumination effects presented to the person on one or more walls or screens in the room, wherein the illumination effects of the visual theme are in accordance with a predetermined ambience for the AHE in the room;
illumination means for illuminating the illumination area of the room that includes the AHE, independent from the visual theme, with illumination conditions for vital sign measurements;
optical measurement means for optically detecting optical detection signals from within said illumination area of the room that includes the AHE;
evaluation means for evaluating said optical detection signals and deriving vital sign information of the person located within the illumination area of the room from the evaluated optical detection signals; and
control means, responsive to feedback from said optical measurement means and said evaluation means, for controlling said illumination means to illuminate said illumination area of the room that includes the AHE to guarantee at least minimum illumination conditions for allowing the detection of optical detection signals from within said illumination area of the room that includes the AHE, from which a predetermined measurement accuracy of the vital sign information of the person can be derived, and further for controlling said presentation means to avoid changes rates in illumination effects of the visual theme for the predetermined ambience for the AHE in the room that interfere with a change rate of a vital sign of the vital sign information being derived from the evaluated optical detection signals.

Abstract
The present invention relates to a device (1) for vital sign measurement of a person (2), comprising presentation means (10) for presenting a person (2) with a visual theme (20), illumination means (11) for illuminating an illumination area (3), in which said person (2) is located, whose vital signs shall be measured, optical measurement means (12) for optically detecting optical detection signals (23) from said illumination area (3), evaluation means (13) for evaluating said optical detection signals (23) and deriving a vital sign information (24) from them, and control means (14) for controlling said illumination means (11) to illuminate said illumination area (3) allowing the detection of optical detection signals (23), from which a vital sign information (24) can be derived despite changes of the visual theme (20).

13. A method for vital sign measurement, the method comprising the steps of:
-
presenting a visual theme within an illumination area of a room to create an ambient healing environment (AHE) of illumination effects for a person located within the illumination area of the room, wherein the AHE comprises direct light from the illumination effects presented to the person and indirect light from reflections of the illumination effects presented to the person of on one or more walls or screens in the room, wherein the illumination effects of the visual theme are in accordance with a predetermined ambience for the AHE in the room; illuminating the illumination area of the room that includes the AHE, independent from the visual theme, with illumination conditions for vital sign measurements; optically detecting optical detection signals from within said illumination area of the room that includes the AHE; evaluating said optical detection signals and deriving vital sign information of the person located within the illumination area of the room from the evaluated optical detection signals; and controlling, in response to feedback from the optically detecting and evaluating steps, said step of illuminating to illuminate said illumination area of the room that includes the AHE to guarantee at least minimum illumination conditions for allowing the detection of optical detection signals from within said illumination area of the room that includes the AHE, from which a predetermined measurement accuracy of the vital sign information of the person can be derived, and further controlling said step of presenting to avoid changes rates in illumination effects of the visual theme for the predetermined ambience for the AHE in the room that interfere with a change rate of a vital sign of the vital sign information being derived from the evaluated optical detection signals. - View Dependent Claims (14, 15)
