After years of investment and development, the wireless devices contained in swallowable capsules are now coming to market. In some situations, doctors can not easily detect diseases and therefore it is too late to cure it. The use of the electronic pill helps us to easily detect diseases and can take a sudden action against it. In 1972, Professor John Cooper and Dr. Eric Johannessen of the University of Glasgow, U.K, have led to the development of the electronic pill. Companies such as Buffalo-based SmartPill and Israel-based Given Imaging (PillCam) imaging camera kits have the size of vitamin tablets. These pills contain sensors or tiny cameras that collect information as they travel through the gastrointestinal tract before being excreted from the body a day or two later. It is a medical surveillance system. The measurement parameters of the electronic pills include temperature analysis, pH measurements, conductivity and dissolved oxygen. And they can also capture images and send them to the Doctor system.
Doctors often use invasive methods such as catheters, endoscopic instruments, or radioisotopes to collect information about the digestive tract. So device companies have been developing easier and less intrusive ways of collecting information. Diseases and digestive disorders can include symptoms like acid reflux, bloating, heartburn, abdominal pain, constipation, difficulty swallowing or loss of appetite. Determining exactly what is happening in the stomach and intestines, "says Dr. Anish A. Sheth, Director of the Gastrointestinal Motility Program at Yale-New Haven Hospital. Doctors can inspect the colon and the par in the stomach with Endoscopic instruments.But some areas can not be easily seen, and discovering how muscles are working can be difficult.Electronic pads are used to measure muscle contraction, ease of passage and other factors to reveal information not available in the past.
