Important Information - Please Read Before Use

Warnings and cautions Follow the warnings and cautions given below when handling this instrument. This information is to be supplemented by the warnings and cautions given in each chapter.

•

This endoscope has a “forward oblique” view. There is a difference between the direction of view and the insertion direction of the endoscope. The insertion direction appears in the lower portion of the endoscopic view, and the visible area in that direction is limited. Always view the endoscopic image carefully, and insert the endoscope prudently. Otherwise, patient injury may occur.

•

Never perform angulation control, perform suction, insert, or withdraw the endoscope’s insertion section without viewing the endoscopic image. Patient injury may 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 injury may 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.

•

Regardless of the flexibility of the endoscope’s insertion section, do not attempt to bend it with excessive force. Otherwise, patient injury may result.

•

This endoscope is not intended for fetal use.

•

Before use, clean and disinfect or sterilize the endoscope as described in Chapter 5 through 8 of this manual.

•

Never perform high-suction continuously. Patient injury can result.

•

Never tie the elastic opening of both sides of the balloon with a thread. This may cause the balloon to rupture or detach from the distal end of the endoscope when inflating it, and could result in patient injury.

•

Never inflate the balloon to a diameter of more than 20 mm when using the endoscope in the trachea. This could result in suffocation of the patient.

•

Never withdraw the endoscope while the balloon is still inflated. Otherwise, the balloon may burst or detach from the distal end of the endoscope. If the balloon cannot be deflated, insert the channel cleaning brush (BW-7B) into the irrigation port. Using slow, short strokes, carefully feed the brush to remove debris.

•

When withdrawing the endoscope, make sure that the balloon is completely deflated, using the ultrasonic image and endoscopic field of view. Withdrawing the endoscope while the balloon is inflated could result in patient injury.

•

Transnasal insertion is accompanied by the risk of inflammation of the nasal cavity. If this happens, the nasal passage will be constricted, making it more difficult to withdraw the endoscope. In this case, do not use force to withdraw the endoscope because patient injury such as bleeding or perforation may result.

•

Transnasal insertion is accompanied by the risk of bleeding in the nasal cavity. Be sure to be prepared to deal with any bleeding. When withdrawing the endoscope, observe the inside of the nasal cavity to ensure that there is no bleeding. Even when the endoscope has been withdrawn without bleeding, do not allow the patient to blow his or her nose strongly because this could cause it to start bleeding.

•

Before transnasal insertion, apply the appropriate pretreatment and lubrication to the patient to enlarge the nasal cavity. Otherwise, patient injury can result or the endoscope could become lodged and be difficult to withdraw. Otherwise, the treatment will have no effect. The effects of the pretreatment agent and lubricant will decrease the longer the procedure lasts. Apply the pretreatment agent or lubricant as required during the procedure – for example, when withdrawal seems to be difficult.

•

Transnasal insertion of the endoscope should be performed carefully. If resistance to insertion is felt, or the patient reports pain, stop insertion immediately. Otherwise, operator and/or patient injury can result or the endoscope could become lodged and be difficult to withdraw.

ULTRASONIC BRONCHOFIBERVIDEOSCOPE BF-UC260FW

Important Information - Please Read Before Use

•

If it becomes impossible to withdraw the transnasally inserted endoscope, detach the ultrasonic cable from the ultrasonic cable connector, pull its distal end out of the mouth, cut the flexible tube using wire cutters and, after ensuring that the cut section will not injure the body cavity or nasal cavity of the patient, withdraw the endoscope carefully. Therefore, always prepare wire cutters in advance.

•

If any irregularity in the ultrasound image is observed, turn the ultrasound center OFF immediately. Continued ultrasound radiation will cause the distal end to become hot and could cause operator and/or patient burns.

•

Elastography*1 uses the pulsation of a living body. Intentional pressurization is not necessary. Compression onto the tissue by operating the bending section, inserting or withdrawing the endoscope may cause tissue damage, bleeding or perforation. 1 Elastography is not available with the diagnostic ultrasound system (Hitachi Aloka Medical, Ltd.) in Canada.

•

Do not pull the universal cord during an examination. The endoscope connector will be pulled out from the output socket of the light source and the endoscopic image will not be visible.

•

Do not coil the insertion section, universal cord, or ultrasonic cable into a diameter of less than 12 cm. Equipment damage can result and/or the ultrasonic image will be abnormal.

•

Do not apply shock to the distal end of the insertion section, particularly the ultrasonic transducer and the objective lens surface at the distal end. Visual abnormalities may result.

•

Do not twist or bend the bending section with your hands. Equipment damage may result.

•

Do not squeeze the bending section forcefully. The covering of the bending section may stretch or break and cause water leaks.

•

The cover of the irrigation port part cannot be removed. Equipment damage can result.

•

Do not hit or bend the electrical contacts on the endoscope connector. The connection to the light source may be impaired and faulty contact can result.

•

Do not attempt to bend the endoscope’s insertion section with excessive force. Otherwise, the insertion section may be damaged.

•

Do not touch the electrical contacts in the ultrasonic connector. Equipment damage can result.

•

Do not pull, twist or tightly coil the ultrasonic cable. Noise can develop in the ultrasonic image.

•

To prevent unnecessary patient exposure to ultrasonic radiation, follow the ‘as-low-as-reasonably achievable’ (ALARA) principle when using Olympus ultrasonic equipment. Freeze the image whenever you are not actively viewing the “live” ultrasonic image. When the equipment is in the FREEZE mode, no ultrasonic energy is emitted.

•

Electromagnetic interference may occur on this instrument near equipment marked with the following symbol or other portable and mobile RF (radio frequency) communications equipment such as cellular phones. If electromagnetic interference occurs, mitigation measures may be necessary, such as reorienting or relocating this instrument, or shielding the location.

•

It is highly desirable that a backup ultrasonic cable be available to continue clinical procedures in case of a malfunction.

•

This endoscope contains a memory chip that stores information about the endoscope and communicates this information to the video system center CV-260 and CV-260SL.

ULTRASONIC BRONCHOFIBERVIDEOSCOPE BF-UC260FW

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. •

Using improperly or incompletely reprocessed or stored instruments may cause patient cross-contamination and infection.

•

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

•

The endoscope has not been designed for use in retroflexed observation. Performing retroflexed observation in a narrow lumen may make it impossible to straighten the angle of the bending section and/or withdraw the endoscope from the patient. In case the patient moves due to coughing and other reasons while the endoscope is angulated in the narrow lumen, the bending section of the endoscope may be pushed into the lumen and be retroflexed. Pretreatment to control patient’s coughing reflex and other possible unexpected moves is the responsibility of trained specialists. Retroflexed observation 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 EndoTherapy accessories without a clear endoscopic image may cause patient injury.

•

Patient injury may be caused by inserting or withdrawing the endoscope or applying suction without a clear endoscopic image.

Natural rubber latex medical alert Balloons used with this instrument contain natural rubber latex that may cause allergic reactions in some patients. Do not use this instrument on a latex-sensitive patient.
