Abstract

A capsule endoscopic device with movement control is disclosed. The capsule endoscopic device comprises a capsule housing, one or more electrodes disposed fixedly through the capsule housing, a signal generation/signal driver unit, an interface circuit and a switch module. The electrodes apply electrical stimulus to living body tissue in a patient'"'"'s gastrointestinal track. The signal generation/signal driver unit generates the electrical stimulus for the electrodes. The switch module is coupled to the electrodes, the signal generation/signal driver unit and the interface circuit. Furthermore, the switch module is configured to connect the electrodes to the signal generation/signal driver unit or the interface circuit depending on an operation mode. The switch module, the signal generation/signal driver unit and the interface circuit are inside the capsule housing

Claims

6-1. The capsule endoscopic device of claim 6, wherein the capsule endoscopic device is set to a data collection mode and the switch module is configured to connect said one or more electrodes to the signal processing circuit during the capsule endoscopic device travels in the patient'"'"'s gastrointestinal track and the signal processing circuit collects electrochemical parameters through said one or more electrodes.

8. The capsule endoscopic device of claim 7, wherein the electrochemical parameters are stored in the second memory.

9. The capsule endoscopic device of claim 8, wherein the second memory corresponds to a second archival memory.

10. The capsule endoscopic device of claim 9, wherein the electrochemical parameters and the image data and/or other sensing data are stored in a same archive memory.
