Ambu aScope Duodeno Bedienungsanleitung Seite 7

Image
Always check whether the image on the screen is a live image or a recorded image and
verify that the orientation of the image is as expected. Do not use this device if the live
image cannot be observed, otherwise, patient injury may occur.
• Always set the intensity of electrosurgical devices to the lowest required value to
avoid image disturbance. Do not increase the level of intensity above the standard
ERCP settings. Always limit the continuous activation time of electrical devices to a
minimum.
• If an abnormal endoscopic image appears or an abnormal function occurs but
quickly corrects itself, the endoscope may have malfunctioned. In this case, consider
abandoning the procedure because the irregularity can occur again, and the
endoscope may not return to its normal condition. Stop the examination immediately
and slowly withdraw the endoscope while viewing the endoscopic image. Otherwise,
patient injury, bleeding, and/or perforation can result.
Over-insufflation & Gas
• Confirm that the top hole of the insufflation/rinsing valve is not blocked. If the hole is
blocked, air is fed continuously and patient pain, bleeding, and/or perforation can result.
• Do not inflate air or a nonflammable gas excessively into the patient. This could cause
gas embolism and/or over-insufflation.
• Do not insufflate flammable gas into the patient. Otherwise, patient injury may occur.
Distal-end Temperature
• The temperature of the distal end of the endoscope may exceed 41 ˚C (106 ˚F) and
reach 50 ˚C (122 ˚F) due to intense endoscopic illumination. Therefore, do not leave
the endoscope illuminated before and/or after an examination and always maintain
a suitable distance necessary for adequate viewing while using the minimum level of
illumination for the minimum amount of time. Continued illumination will cause the
distal end of the endoscope to become hot and cause operator and/or patient burns.
• Avoid long periods of contact between the tip of the device and the mucosal
membrane, sustained contact with the mucosal membrane may cause mucosal injury.
The distal end of the endoscope may get warm due to heating from the light emitting
part. When withdrawing the endoscope, the distal end should be in the neutral and
non-deflected position with the brakes released.
Biopsy Valve
• Before using a syringe to inject liquid through the biopsy valve or when aspirating,
detach the valve's cap from the main body. If the cap is not detached and/or the
syringe is not inserted straight, the biopsy valve could be damaged. This could reduce
the efficacy of the endoscope's suction system, and may leak or spray patient debris or
fluids, posing an infection control risk. If the biopsy valve is left uncapped during the
procedure, debris or fluids could leak or spray from it, posing an infection control risk.
When the valve is uncapped, place a piece of sterile gauze over it to prevent leakage.
• Patient debris might spray when endoscopic accessories are withdrawn from the
biopsy valve. To prevent this, hold a piece of gauze around the accessory and the
biopsy valve during withdrawal.
• Do not let the endoscopic accessory hang down from the biopsy valve. This can
damage the valve, which can reduce the efficacy of the endoscope's suction system
and may leak or spray patient debris or fluids, posing an infection control risk.
• Do not use the biopsy valve if any irregularities are observed during the inspection.
An irregular, abnormal, or damaged valve can reduce the efficacy of the endoscope's
suction system, and may leak or spray patient debris or fluids, posing an infection
control risk. Replace with a new one if necessary.
