Abstract

A capsulated body having a facility, which acquires biomedical information through endoscopic examination or the like, incorporated therein is inserted into a duct within a living body. Whether the capsulated body has halted for a certain period of time is detected from the time-varying position of the capsulated body or a time-passing change in an image. If it is judged that the capsulated body has halted at a stenosed region or the like, the fact is notified so that the capsulated body can be collected immediately.

Claims

1-14. -14. (canceled)

15. A capsulated medical equipment comprising:

a capsulated body that is inserted into a living body and passed through a duct in the living body;

a driving unit for causing a needle to thrust and sink from the capsulated body; and

a control unit for controlling the driving unit.

16. The capsulated medical equipment according to claim 15, wherein the needle is an injector.

17. The capsulated medical equipment according to claim 16, wherein a hemostatic agent is injected in a bleeding region by the injector.

18. The capsulated medical equipment according to claim 17, wherein the hemostatic agent is ethanol.

19. The capsulated medical equipment according to claim 15, further comprising a position detection unit that detects the position of the capsulated body.

20. The capsulated medical equipment according to claim 15, wherein the capsulated body is the one in which a magnet or magnetic substance that reacts on magnetic forces is incorporated.

21. The capsulated medical equipment according to claim 20, further comprising a guiding assembly for guiding the capsulated body to move by utilizing magnetic forces.

22. A method of arresting bleeding in a living body comprising:

step of inserting a capsulated body into a living body;

step of detecting a bleeding region by the capsulated body;

step of causing an injector to thrust and sink in the bleeding region; and

step of injecting a hemostatic agent in the bleeding region by the injector.

23. The method of arresting bleeding in a living body according to claim 22 wherein the step of detecting a bleeding region is the one of detecting the bleeding region by an observation unit.

24. The method of arresting bleeding in a living body according to claim 22 wherein the step of detecting a bleeding region is the one of detecting the bleeding region by a blood sensor.

25. The method of arresting bleeding in a living body according to claim 22 wherein the step of injecting a hemostatic agent is the one of injecting ethanol as the hemostatic agent.

26. The method of arresting bleeding in a living body according to claim 22, further comprising step of guiding the capsulated body.

27. The method of arresting bleeding in a living body according to claim 26, wherein the step of guiding the capsulated body is the one of guiding the capsulated body magnetically.
