When the capsule endoscope is turned ON, the LED illuminates.Figure 5.44Inner lid of sterile containerOuter lid of sterile containerCapsule activatorInsertCapsule endoscope insertion holeBossGroove
Chapter 5 Capsule Endoscope Procedures131OLYMPUS CAPSULE ENDOSCOPE SYSTEM• The capsule activator is not sterilized. Do not allow the capsule endoscope to touch the activator.• Keep the capsule endoscope away from magnets.Magnets can turn the capsule endoscope ON, resulting in the consumption of battery power.• Do not look directly at the capsule endoscope’s LED for a prolonged duration. It may cause an afterimage.Inserting the capsule activator again will turn the capsule endoscope OFF.Confirming imageTo avoid unnecessary consumption of battery power, once the capsule endoscope has been turned ON, perform the image confirmation quickly.1. Bring the capsule endoscope in the sterile container close to an antenna of the antenna lead set and confirm that the images captured by the capsule endoscope are displayed on the real time viewer’s display panel. Also confirm that the recorder unit’s display lamp blinks green simultaneously with the transmission.• Do not let the patient ingest the capsule endoscope until you confirm the green blinking of the recorder unit’s indicator lamp. Failure to do so may interfere with the examination.• If the capsule endoscope images are not displayed, remove the viewer cable from the real time viewer, and check if images can be displayed via direct reception by the real time viewer. If images are still not displayed, try using a different capsule endoscope.You can check for proper operation of the equipment by periodically inspecting the status of the indicator lamp.2. Disconnect the real time viewer cable from the recorder unit, close the rubber cap for the viewer cable connector, and close the connector cover.
132Chapter 5 Capsule Endoscope ProceduresOLYMPUS CAPSULE ENDOSCOPE SYSTEM5.8 Starting the examinationInstruct the patient to follow the cautions for Capsule Endoscopy Patients in the Capsule Endoscope Set A.Also instruct the patient to return to the hospital 8 hours after the beginning of the examination.DispensingDo not use a capsule endoscope that has been dropped, bitten or subjected to excessive pressure. Using such endoscopes may result in internal injury to the patient due to equipment damage.• The capsule endoscope should only be ingested with water. Use of other liquids may interfere with the examination.• Avoid touching the top cover (LED side) of the capsule endoscope. Do not wipe with gauze or other cloths.1. Prepare a glass of water.2. Remove the inner case, and hand it to the patient.3. Confirm that the capsule endoscope’s LED is blinking.4. Instruct the patient to take the capsule endoscope out of the inner case and ingest it with a sip of water, and not to bite the capsule.Confirming passageUsing the real time viewer, confirm that the capsule endoscope has passed the stomach and entered the duodenum. Prolonged delay of the passage may result in the examination ending prematurely due to low battery.• In general, the capsule endoscope reaches the duodenum about 2 hours after ingesting the capsule endoscope, though this time may vary from patient to patient.• The duration of the capsule endoscope’s presence within the stomach varies from patient to patient. For this reason, you may not be able to capture images for the entire small intestine.
Chapter 5 Capsule Endoscope Procedures133OLYMPUS CAPSULE ENDOSCOPE SYSTEM5.9 During the examinationFamiliarize the patient with the following dangers, warnings and cautions.The capsule endoscope contains metal parts. While the capsule endoscope is in your body, stay away from equipment (i.e. MRI equipment) for which wearing of metallic objects is prohibited.Immediately consult a physician if abdominal pain, discomfort, or nausea is experienced after the patient ingests the capsule endoscope. If treatment is delayed, it may result in injury to the body cavity.• With allergic patients, reddening or irritation of the skin may be caused by the adhesive on the antenna lead cover.• Do not remove the antenna lead set or the recorder unit harness until the examination is completed. Failure to follow instructions may interfere with the examination.• Do not turn the recorder unit OFF, remove the battery pack from the recorder unit, or disconnect the antenna lead set during the examination.
