Abstract

A device for hemorrhage detection comprising a detecting means for detecting the presence of blood, said detecting means being connected to a fixing means. The fixing means is fixed to the inner wall of a hollow organ. The device further has a transmitting unit by which the data transmitted by the detecting means are adapted to be transmitted to a receiving unit disposed outside the body.

Claims

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.

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 an endoscopic clip or anchor.

6. The device for hemorrhage detection according to claim 1, wherein the fixing means is a stent-like structure.

7. The device for hemorrhage detection according to claim 1, wherein the fixing means is made of a biodegradable material.

8. The device for hemorrhage detection according to claim 1, wherein the fixing means is connected to the detecting means via a connecting member.

9. The device for hemorrhage detection according to claim 8, wherein the connecting member is made of a biodegradable material.

10. The device for hemorrhage detection according to claim 1, wherein the detecting means detects a presence of blood by measuring specific absorption spectra of a content present in the hollow organ.

11. The device for hemorrhage detection according to claim 1, wherein the detecting means is adapted to differentiate between different manifestations of blood.

12. The device for hemorrhage detection according to claim 11, wherein the different manifestations of blood comprise venous blood, arterial blood or clotted blood.

13. The device for hemorrhage detection according to claim 1, wherein the detecting means comprises at least one photosensitive sensor.

14. The device for hemorrhage detection according to claim 13, wherein the photosensitive sensor is a photodiode or a phototransistor.

15. The device for hemorrhage detection according to claim 1, wherein the detecting means further comprises at least one light source.

16. The device for hemorrhage detection according to claim 15, wherein the light source is an LED.

17. The device for hemorrhage detection according to claim 15, wherein the light source emits light in the UV range, light in the red range of the visible spectrum, or a combination thereof.

18. The device for hemorrhage detection according to claim 17, wherein the detecting means detects a presence of blood by measuring specific absorption spectra of a content present in the hollow organ and wherein in a signal processing step following the measurement, a quotient is formed from the sensor signal depending on the intensity of the transmitted red light and the sensor signal depending on the intensity of the transmitted UV light.

19. The device for hemorrhage detection according to claim 1, wherein the detecting means comprises a measuring gap.

20. The device for hemorrhage detection according to claim 19, 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.

21. The device for hemorrhage detection according to claim 1, wherein the fixing means comprises a means for stanching blood of a bleeding source.

22. The device for hemorrhage detection according to claim 21, wherein the means for stanching blood of a bleeding source is an endoscopic hemostasis clip
