Problems solved by technology

However, in a hospital environment, for example, with the patient lying in bed and covered with blankets, only very limited breathing movements can be observed
Also, chest movement does not guarantee gas flow into the lungs
Additionally, motion-based respiration measurements are susceptible to motion artifacts

Embodiment Construction

[0046] figure 1 An exemplary embodiment of a system 1 for determining vital sign information 7 of a subject 100 according to an aspect of the invention is shown. The system 1 comprises a marker 10 for application to an object 100, a detection unit 2 and an analysis unit 6 as basic components. In this example, the system 1 for determining vital sign information 7 of a subject 100 is employed in a clinical setting, wherein the subject 100 is lying on a bed 200 .

[0047] The marker 10 is configured to change optical properties in response to a physiological process of the subject 100 . In this example, the detection unit 2 is connected to an optional image processing unit 4 . The detection unit 2 supplies radiation data 3 representing the detected radiation to the image processing unit 4 in the form of a video stream. The image processing unit 4 identifies markers 10 in the radiation data 3 . The image processing unit 4 is in turn connected to an analysis unit 6 . The image...

Abstract

The present invention relates to a system (1) and method for determining vital sign information (7) of a subject (100). The system comprises a marker (10, 10', 10'', 40) for application to the subject (100), wherein the marker (10, 10', 10'', 40) is configured to change an optical property due to a mechanical manipulation of the marker (10, 10', 10'', 40) caused by a physiological process of the subject (100), a detection unit (2) for detecting radiation from the marker (10, 10', 10'', 40), and an analysis unit (6) for determining the vital sign information (7) of the subject (100) from the detected radiation.

Description

technical field [0001] The present invention relates to systems and methods for determining vital sign information of a subject, and more particularly to optical measurements for remotely determining vital sign information of an observed subject. Background technique [0002] A subject's vital signs, such as heart rate (HR), respiration rate (RR) or body temperature, are used as indicators of a person's current state of health and as powerful predictors of serious medical events. For this reason, vital signs are widely monitored in inpatient care settings and outpatient care settings, at home or in other health, leisure and fitness settings. [0003] US2009 / 0204100A1 discloses a body covering comprising a temperature sensing element. The temperature sensing element senses the temperature of the proximal skin and converts the locally sensed temperature into a visual and / or electrical signal. The body covering may include a partial display for converting the electrical signa...
