ABSTRACT: Gastric disorders play an
important role in digestive system of a human subject. Gastric disorder is due
to the gastric dysmotility due to delayed gastric emptying and other motor
dysfunctions like impaired fundic distention. Nowadays invasive technique like
laparoscopy procedure, endoscopy procedure and surgery procedure plays a vital
role in investigation of gastric disorders. Electrogastrogram is a noninvasive
technique for analyzing digestive system disorders. In this proposed work,
stimulation is delivered with the electrode package with camera, which travels
through an esophagus to reach stomach and stimulate the interstitial cajal
cells. Due to this stimulation the stomach starts, its activity a potential is
provided that is recorded with electrode setup, which is called
electrogastrogram. It is verified with its normal range 3 cpm. The stimulation
includes pulses mode and continuous mode. Stomach function is recovered and its
frequency is measured and the same is compared with normal range value.
Depending upon the subject condition, the gastric activity is improved by
setting different values of duty cycle. By this procedure the subject avoid painful
procedure, stay in hospital, frequently and the cost is minimum.
