Important Information - Please Read Before Use

•

Never perform angulation control forcibly or suddenly. Never forcefully pull, twist or rotate the angulated bending section. Patient injury, bleeding and/or perforation can result.

•

Never insert or withdraw the endoscope’s insertion tube while the bending section is locked in position. Patient injury, bleeding and/or perforation can result.

•

Never insert or withdraw the insertion tube abruptly or with excessive force. Patient injury, bleeding and/or perforation can result.

•

Do not touch the light guide of the endoscope connector immediately after removing it from the light source because it is extremely hot. Operator or patient burns can result.

•

Before each use or after a change of viewing modes/settings, check to ensure the view observed through the endoscope provides a live image (rather than a stored one) and has the correct image orientation. Otherwise, patient injury, bleeding, and/or perforation could result.

•

When the endoscopic image does not appear on the monitor, the CCD may have been damaged. Turn the video system center OFF immediately. Continued power supply in such a case will cause the distal end to become hot and could cause operator and/or patient burns.

•

If it is difficult to insert the endoscope, do not forcibly insert the endoscope; stop the endoscopy. Forcible insertion can result in patient injury, bleeding and/or perforation.

•

This endoscope is not intended for fetal use.

•

Important Information - Please Read Before Use

Examples of inappropriate handling Details on clinical endoscopic technique are the responsibility of trained specialists. Patient safety in endoscopic examinations and endoscopic treatment can be ensured through appropriate handling by the physician and the medical facility. Examples of inappropriate handling are given below; •

Over-insufflating the lumen may cause patient pain, injury, bleeding and/or perforation.

•

Applying suction with the distal end in prolonged contact with the mucosal surface, with higher suction pressure than required or with prolonged suction time may cause bleeding and/or lesions.

•

The endoscope has not been designed for use in retroflexed observation in parts of the body other than the stomach. Performing retroflexed observation in a narrow lumen may make it impossible to straighten and/or withdraw the endoscope. Retroflexed observation in parts of the body other than the stomach should be performed only when the usefulness of doing so is determined to be greater than the risk that is posed to the patient.

•

Inserting, withdrawing and using endo-therapy accessories without a clear endoscopic image may cause patient injury, burns, bleeding and/or perforation.

•

Inserting or withdrawing the endoscope, feeding air, applying suction or operating the bending section without a clear endoscopic image may cause patient injury, bleeding and/or perforation.

Natural rubber latex medical alert Balloons used with this instrument contain natural rubber latex which may cause allergic reactions in some patients. Do not use the balloon on a latex-sensitive patient. Instead, perform the procedure using “The sterile de-aerated water immersion method” described in Section 4.2, “Observation of the ultrasonic image”.
