GASTROINTESTINAL ELECTRONIC PILL

摘要

The present invention relates to an electronic gastrointestinal capsule protected by an outer biocompatible shell resistant to the environment in the digestive system comprising a light source (4); splitting means (5) to split the light beam, directing it to the reference arm (6) and the sampling arm (9); an adjustable group delay element (24) depending on the distance to the tissue to analyse; optical moving means moving the intersection of the light beam (30) of the sampling arm (9) across the tissue; an optical system (8) focusing the light beam (30) from the sampling arm (9) on the tissue; interference means (10) producing interference between the reflected light; a detector (11) receiving said interference; processing means (2) processing the information acquired by the detector (11); and power supply means (3) supplying power to the capsule without a physical connection to the outside.

1. An electronic gastrointestinal capsule having an outer biocompatible shell resistant to the environment in the digestive system and comprising:
at least one light source; a splitter configured to split a light beam coming from the light source and direct the light beam to a reference arm and a sampling arm; an adjustable group delay element disposed in at least one of the arms; an optical moving element configured to move an intersection of the light beam of the sampling arm across a tissue surface; an optical system configured to focus the light beam from the sampling arm on the tissue surface; an interference element configured to produce an interference signal between reflected light coming from the sampling arm and the reference arm; at least one detector configured to receive the interference signal between the light coming from the reference arm and sampling arm; a processor configured to process the information acquired by the detector; and a power supply configured to electrically supply power to the capsule without a physical connection to the outside of the capsule.
