4. Use of aScope 3
Numbers in gray circles below refer to illustrations on page 2.
4.1. Preparation and inspection of aScope 3
Visual inspection of the endoscope 1
Check that the pouch seal is intact. 1a
1.
2. Make sure to remove the protective elements from the handle and from the insertion
cord. 1b
3. Check that there are no impurities or damage on the product such as rough surfaces,
sharp edges or protrusions which may harm the patient. 1c
Refer to the displaying unit Instruction for use for preparation and inspection of the dis-
playing unit 2
Inspection of the image
1. Plug in the endoscope cable connector into the corresponding connector on the compati-
ble displaying unit. Please ensure the colours are identical and be careful to align the
arrows. 3
2. Verify that a live video image appears on the screen by pointing the distal tip of the endo-
scope towards an object, e.g. the palm of your hand. 4
3. Adjust the image preferences on the displaying unit if necessary (please refer to the dis-
playing unit Instruction for use).
4. If the object cannot be seen clearly, wipe the lens at the distal tip using a sterile cloth.
Preparation of the endoscope
1. Carefully slide the control lever forwards and backwards to bend the bending section as
much as possible. Then slide the control lever slowly to its neutral position. Confirm that
the bending section functions smoothly and correctly and returns to a neutral position. 5a
2. Using a syringe insert 2ml of sterile water into the working channel port (if applying a
Luer Lock syringe use the enclosed introducer). Press the plunger, ensure that there are
no leaks, and that water is emitted from the distal tip. 5b
If applicable, prepare the suction equipment according to the supplier's manual. 5c
3.
Connect the suctioning tube to the suction connector and press the suction button to
check that suction is applied.
4. If applicable, verify that endoscopic accessory of appropriate size can be passed through
the working channel without resistance. The enclosed introducer can be used to facilitate
the insertion of soft accessories such as microbiology brushes. 5d
5. If applicable, verify that endotracheal tubes and double lumen tubes are compatible with
the endoscope before starting the procedure.
4.2. Operating the aScope 3
Holding the endoscope and manipulating the tip 6a
The handle of the endoscope can be held in either hand. The hand that is not holding the
endoscope can be used to advance the insertion cord into the patient's mouth or nose.
Use the thumb to move the control lever and the index finger to operate the suction button.
The control lever is used to flex and extend the distal tip endoscope in the vertical plan. Moving
the control lever downward will make the distal tip bend anteriorly (flexion). Moving it upward
will make the distal tip bend posteriorly (extension). The insertion cord should be held as
straight as possible at all times in order to secure an optimal distal tip bending angle.
Tube connection 6b
The tube connection can be used to mount ETT and DLT with an ISO connector during intubation.
Insertion of the endoscope 7a
Lubricate the insertion cord with a medical grade lubricant when the endoscope is inserted
into the patient. If the camera image of the endoscope becomes unclear the distal tip can be
cleaned by gently rubbing the distal tip against the mucosal wall or remove the endoscope
and clean the distal tip. When inserting the endoscope orally, it is recommended to use a
mouthpiece to protect the endoscope from being damaged. It is recommended to remove
introducer from the working channel port when it is not in use
