Patent Images
1. A device for hemorrhage detection, comprising a fixing means mountable inside a hollow organ, and a detecting means connected to the fixing means for detecting a presence of blood, the device further comprising:
- a light source configured to emit light in an ultraviolet (UV) range and light in a red range of the visible spectrum;
at least one photosensitive sensor configured to measure a first light intensity depending on absorption in the UV range and a second light intensity depending on absorption in the red range of the visible spectrum, and to output a first sensor signal depending on the first light intensity and a second sensor signal depending on the second light intensity; and
a calculation unit configured to calculate a ratio of the first sensor signal and the second sensor signal, wherein the ratio comprises a parameter determining whether blood is present or not present.
