Abstract

Body monitoring device, having a surface and configured to be applied to and/or near the body, comprising at least one light source and at least one photo detector. The at least one light source emits light in at least a direction away from the surface. The at least one photo detector is configured to detect light that is emitted by the at least one light source and reflected by the body in a direction towards said surface.

Claims

1. A body monitoring device, having a surface and configured to be applied to and/or near the body, comprising:

at least one light source; and

at least one photo detector, wherein the at least one light source emits light in at least a direction away from said surface and wherein the at least one photo detector is configured to detect light that is emitted by the at least one light source and reflected by the body in a direction towards said surface, wherein the body monitoring device is at least partly flexible for substantially extending along the curves of the body, wherein the body monitoring device has a lateral direction parallel to said surface and has a thickness perpendicular to said lateral direction, wherein the thickness is less than approximately 7 millimeters, and wherein the body monitoring device is further configured to apply dynamic phototherapy, said body monitoring device further including a control system configured to process the detected light into oxygen saturation values, wherein said control system is responsive to the oxygen saturation values for dynamically adjusting the light emitted from the at least one light source for monitoring a specific portion of the body and said control system is responsive to the oxygen saturation values for dynamically adjusting the light emitted from the at least one light source for optimizing phototherapy applied to said specific portion of the body.

2. The body monitoring device according to claim 1, wherein the at least one light source is configured to emit light at multiple wavelength ranges.

3. The body monitoring device according to claim 1, wherein the at least one photo detector is configured to detect light of multiple wavelength ranges that correspond to multiple depths and/or parts of the body.

4. The body monitoring device according to claim 1, wherein the at least one light source is configured to be tuned to emit the light within a wavelength range defined between a lowest value and a highest value.

5. The body monitoring device according to claim 1, wherein the at least one photo detector is positioned in the same plane as the at least one light source and/or in a parallel plane thereof.

6. The body monitoring device according to claim 1, wherein the at least one light source comprises a LED (light emitting diode) and/or OLED (organic light emitting diode).

7. The body monitoring device according to claim 1, wherein the thickness is less than approximately 5 mm.

8. The body monitoring device as defined in claim 1, wherein said control system dynamically adjusts at least the wavelength of the light for performing monitoring, and wherein said control system dynamically adjusts at least one characteristic of the light for performing phototherapy, said at least one characteristic selected from the group including wavelength, intensity, pulse width, pulse peak intensity, pulse duty cycle, pulse peak height, pulse repetition rate, and total time of illumination.
