Embodiment Construction

[0042] Contact (PPG) sensors can be used (and recently video cameras (rPPG) can be used) to detect vital signs such as blood volume and pulse that cause periodic changes in human skin color. In this way, various vital signs (pulse, oxygenation level, respiration, etc.) can be monitored. Similarly, such sensors (especially cameras) are used to monitor patient movement for sleep somatograph and / or respiratory movement detection.

[0043] Once vital sign detectors are widely introduced in hospitals, there is an increasing need to verify the calibration of these vital sign detectors (for example, vital sign cameras). Moreover, before new detectors are introduced to the market, these detectors may need to be tested in order to obtain sufficient performance.

[0044] For this reason, the present invention proposes to use a virtual phantom (for example, a virtual phantom in the form of a human body part (for example, face) or the entire body) in the environment presented at the monitor, ...

Abstract

The present invention relates to a method and a device for enabling to analyze a property of a vital sign detector (20). The proposed method comprises the steps of providing a virtual phantom (14) ofa living being, rendering an artificial vital sign on the displayed virtual phantom (14), and outputting the virtual phantom (14) with the rendered artificial vital sign to the vital sign detector (20).

Description

Technical field [0001] The present invention relates to a method, device and system for enabling analysis of the performance of a vital sign detector. In particular, the present invention relates to calibrating or testing vital signs cameras for monitoring various vital signs (eg, pulse, oxygenation level, respiration, etc.). Background technique [0002] Traditionally, hospitals (especially ICUs) have health monitoring, which includes monitoring vital signs such as EEG, ECG, pulse rate, respiration rate, blood oxygen level, blood pressure and the like. Moreover, in addition to using some vital signs, the sleep laboratory also uses body motion and electromyography to collect information about sleeping subjects. [0003] These application areas usually involve multiple sensors attached to the patient’s body, some of which can be wireless while others are wired. In addition to causing discomfort and possible skin damage, this situation also limits the patient The freedom of movemen...
