Device for hemorrhage detection
View Patent ↗A device for hemorrhage detection comprising a detector for detecting the presence of blood, the detector being connected to a fixing, apparatus. The fixing apparatus is fixed to the inner wall of a hollow organ. The device further has a transmitting unit by which data transmitted by the detector are adapted to be transmitted to a receiving unit disposed outside the body.
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.
2. The device for hemorrhage detection according to claim 1 , further comprising a transmitting unit for sending data detected by the detecting means, and a receiving unit for receiving the data sent by the transmitting unit.
3. The device for hemorrhage detection according to claim 2 , wherein the transmitting unit is formed to be encapsulated.
4. The device for hemorrhage detection according to claim 2 , wherein the transmitting unit transmits data to the receiving unit wirelessly.
5. The device for hemorrhage detection according to claim 1 , wherein the fixing means is made of a biodegradable material.
6. The device for hemorrhage detection according to claim 1 , wherein the connecting member is made of a biodegradable material.
7. The device for hemorrhage detection according to claim 1 , wherein the photosensitive sensor is a photodiode or a phototransistor.
8. The device for hemorrhage detection according to claim 1 , wherein the light source is an LED.
9. The device for hemorrhage detection according to claim 1 , wherein the detecting means comprises a measuring gap.
10. The device for hemorrhage detection according to claim 9 , wherein the detecting means further comprises a light source wherein light emitted by the light source is able to pass through the interior of the hollow organ in the area of the measuring gap.
11. The device for hemorrhage detection according to claim 1 , wherein the fixing means comprises a means for stanching blood of a bleeding source.
12. The device for hemorrhage detection according to claim 11 , wherein the means for stanching blood of a bleeding source is an endoscopic hemostasis clip.
13. The device for hemorrhage detection according to claim 1 , wherein the light source is configured to emit light successively in the UV range and in the red range of the visible spectrum.
14. The device for hemorrhage detection according to claim 1 , wherein the device comprises two light sources, a first light source emitting light exclusively in the UV range and a second light source emitting light exclusively in the red range of the visible spectrum.
