Embodiment Construction

[0067] exist figure 1 A device 10 for measuring the hydration state of an organism according to an embodiment of the present invention is illustrated in FIG. In order to derive a body hydration index indicative of the hydration state of the organism, the reflectance of the tissue portion 12 was assessed. A first light source 14 , preferably incorporated by an LED, emits light at a first wavelength into tissue portion 12 . Before entering the tissue portion 12 at least part of the light is polarized by means of the polarizing unit 18 . exist figure 1 In an embodiment, the emitted light passes through a beam splitter 20. The emitted light then interacts with the tissue portion 12 . The interaction corresponds in particular to the reflection of light portions at the surface of the tissue portion 12 . Another part of the light can be backscattered. figure 1 The arrows in , illustrate the possible paths of the emitted light 16 , the directly reflected light portion 22 and the...

Abstract

The present invention relates to a device (10) and method for non-invasively measuring a hydration state of a living being (62). To improve with respect to the convenience-to-use, the cost-effectiveness and the accuracy of the delivered results, the proposed device comprises a first light source (14) for emitting light of a first wavelength into a tissue portion (12) of the living being (62), polarization means (18) for polarizing at least part of the emitted light prior to an interaction of the emitted light with the tissue portion (12), a first light detector (26) for detecting polarized light of the first wavelength reflected at the tissue portion (12) and processing means (32) configured to derive a tissue hydration parameter from the detected reflected polarized light and to determine a body hydration index based on said tissue hydration parameter.

Description

technical field [0001] The invention relates to a device for measuring the hydration state of an organism and a corresponding method. Background technique [0002] Dehydration, especially from gastroenteritis or other disorders that cause vomiting, diarrhea, and fever (eg, pyloric stenosis, hyperthyroidism, diabetes insipidus, cystic fibrosis, intestinal ischemia, etc.), is a common pediatric disease. According to the Centers for Disease Control and Prevention, the annual incidence of diarrheal disease among children younger than 5 years is approximately 1.5 billion, and the annual death toll is estimated to be between 1.5 million and 2.5 million. In addition, there is significant evidence that growth causes changes in body water composition, and that kidney function and thirst perception decline, on average, in older adults. These three factors take into account the prevalence of dehydration in the elderly population. In one study, 6.7 percent of hospitalized patients ag...
