Pill Camera in Capsule Endoscopy – Uses and Mode of Working of Pill Camera


Pill Camera in Capsule Endoscopy

Today we can see that there is a leading development in the medical sector. This is the only way in the advancement of technology in the medical applications. The innovative technology in medical applications play an important role in the development of this sector.

One of the effective advanced technology used in the medical application is “Pill Camera”. It is a nanotechnology product used in the process of Endoscopy. Endoscopy is a procedure to diagnose and examine the conditions of the inner parts of our body. Doctors use special instruments to view the internal organs and vessels and diagnose the diseases. It is the process of inserting a tube through your mouth.

There is a small camera attached to the one end of the tube, so the images of your internal part of the body is shown in the nearby monitor. This process helps the doctors  to view problems within your body without making large incisions. Endoscopy is a pain stacking process not only for patients but also for the doctors and nurses as well. In order to solve this problem a wireless capsule endoscopy has emerged.

Pill Camera is used capsule endoscopy for the visualization of the bowel wall and lumen. It  was 1-1/8 inches long and 3/8 inches wide. It was the size of a large pill and it had an 8-hr battery, light source, a camera, and a small transmitter.

Components of Pill Camera

Pill camera consists of 8 components. Following are the components of capsule camera or pill camera.

1.Optical Dome: It helps propel the capsule forward easily.

2. Lens Holder: It accommodates the lens.

3. Lens: It is arranged behind the Light Receiving Window.

4.Illuminating LED’s : Around the Lens & CMOS Image Sensor, four LED‟s (Light Emitting Diodes) are present

5. CMOS Image Sensor : It is highly sensitive and produces very high quality images

6. Battery: Battery used in the capsule is button shaped and two in number. Silver Oxide primary batteries are used

7. ASIC Transmitter: It is arranged behind the Batteries.

8. Antenna: It is arranged at the end of the capsule. It is enclosed in a dome shaped chamber

How the Pill Camera works?

  • A pill sized video camera ( pill camera ) is given to the patients to swallow.
  • The camera has its own light sources and take the pictures of small intestine as it passes through.
  • It produces two frames per second with an approximate of 56,000 high quanlity images.
  • These pictures are send to the recording device, which has to wear on the body.
  • Then the doctor examine these pictures and provide instructions and guideline about if any diseases in your small intestine.

The Invention of Pill Camera Makes What Difference in the Medical Field ?

The evolution of wireless endoscopy makes a global standard for digestive diagnosis in the medical fields. Now in order to identify gastrointestinal diseases of your body, the patients now swallow a tiny camera that keep the images inside the body that the doctors to evaluate.

  • Pill camera in capsule endoscopy helps the doctor to evaluate the small intestine.
  • This part of the bowel can’t be reached by traditional upper endoscopy or by colonoscopy.
  • It is the painless way looking into the small intestine.
  • Common reason for doing capsule endoscopy is to search for a cause of bleeding from the small intestine.
  • It helps in detecting polyps, inflammatory bowel disease or Crohn’s disease, ulcer’s and tumors of small intestine, etc.

Advantages of Pill Camera

PillCamera had a tremendous success in the medical applications in the world.

  • Pill camera permits a direct visual examination of the small intestine.
  • It helping diagnose a problem which doctor previously would have found only through surgery.
  • It is more healthy than X-rays and radioactive tracing of stomach tumors.
  • Pill Camera provide improved safety and accuracy.
  • It is safe and well tolerated.
  • Wireless capsule endoscopy represents a significant technical breakthrough for the investigation of the small bowel
  • The pill camera in capsule endoscopy seems can suit to patients with gastrointestinal bleeding of unclear etiology.
