Preparing the capsule endoscope
Do not use a capsule endoscope that have been dropped,
bitten or been subjected to excessive pressure. Using such a
capsule endoscope may result in infection of patient and/or
medical personnel, as well as internal injury to the patient
due to equipment damage.
•
If the sterile container is open or damaged, the sterility of the
capsule endoscope may have been compromised. Use a
new capsule endoscope instead.
•
To prevent the capsule endoscope battery from deteriorating,
store the capsule endoscope under a temperature of 0 to
25°C (39 to 77°F). Do not store in a refrigerator or a freezer,
as condensation may result.
Clean the capsule activator with a cotton swab soaked in
70% ethyl or isopropyl alcohol.

•
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 image
To 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.

5.8
Starting the examination
Instruct 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.
Dispensing
Do 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 passage
Using 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.
132
•
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.
OLYMPUS CAPSULE ENDOSCOPE SYSTEM
Chapter 5 Capsule Endoscope Procedures
5.9
During the examination
Familiarize 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. Failure to follow instructions may
interfere with the examination.
•
During the examination, avoid pointing radio-transmitting
devices (i.e. keyless entry, home security, waitress call
system, garage door remote, wireless headphones, ham
radio, etc.) at the antenna leads.
