After years of investment and
development, wireless devices contained in swallowable capsules are
now reaching the market. At some
situations, doctors can’t easily detect diseases and hence it becomes too late to
cure it. Use of electronic pill helps us to easily detect the diseases and can
take suddenaction against it. In 1972,
Professor John Cooper and Dr. Eric Johannessen from Glasgow University, U.K has
led to the development of electronic
pill. Companies such as SmartPill based
in Buffalo, New York and Israel-based Given Imaging (PillCam) market capsules
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 monitoring
system. Measurement parameters of electronic pills include temperature
analysis, pH measurements, conductivity and dissolved oxygen. And they can also
capture images and sent it into Doctor's system. Doctors often use invasive methods such as
catheters, endoscopic instruments or radioisotopes for collecting information about
the digestive tract. So device companies have been developing easier, less intruisive ways to gather information.Digestive diseases and disorders can include
symptoms such as acid reflux, bloating, heartburn, abdominal pain,
constipation, difficulty swallowing or loss of appetite."One of the main challenges is
determining just 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
peer into the stomach using endoscopic instruments. But some areas cannot be
easily viewed, and finding out how muscles are working can be difficult. Electronic pills are being used to measure
muscle contraction, ease of passage and other factors to reveal information
unavailable in the past.
WORKING-
When it moves through gastro-intestinal track it starts to detect diseases and abnormalities. A small electronic pill can easily reach areas such as small intestine and large intestine and can deliver real time information to an external system. Total information will be displayed in a monitor. The electronic pill travels to the digestive system, collects data and sends it into the computer with a distance of 1 meter and more. Main parts of electronic pills are four sensors, an ASIC chip, a radio transmitter and a power source.
