The pill cam was invented by Israeli inventor Gavriel Iddan in the 1990s. The pill has an 8-hour battery, light sources (LED light), a camera, antenna, and a small transmitter. From the time of ingestion, the pill works for 8 hours which takes 2 pictures per second for a total of 55,000 images. The length of the pill is 26 mm * 11 mm and weighs 4 grams.
A pill cam is consumed to analyze the abnormal internal body functions which are commonly known as endoscopy. Endoscopy is the procedure of inserting a thin tube fixed with a camera that is used to diagnose the problems in the digestive tract like the Esophagus, Stomach, and Duodenum (beginning of the small intestine). Though it can take clear internal images, it may also lead to some complications like perforation (tear in the gut wall), infection, and bleeding.
To overcome those drawbacks in the endoscopy, a pill camera can be used. The pill cam was approved for use by the FDA (Food and Drug Administration) in 2001.
- Eight adhesive sensors will be placed in the patient’s abdomen.
- Patients shouldn’t take food at least 12 hours before the procedure.
- The patient is allowed to swallow the pill cam which passes along the gastrointestinal tract.
- The cam pill takes n number of photos while passing the digestive tract.
- The images will be transmitted wirelessly to an array of receivers connected to the portable recording device carried by the patient.
- The capsule naturally passes after 8 to 72 hours, even it can take up to 2 weeks.
The pill cam is a painless, non-invasive, and effective method to diagnose the internal body malfunctions. The accuracy rate measured by the pill cam may vary up to 83% to 89% which detects most of the interior problems even cancer.
