3. Disinfectants based on or containing alcohol can damage the filter.
4. The locking cap must be screwed on before you disinfect the filter.
5. Always ensure that the correct function of the nerve stimulator being used
is applied, and that suitable current strengths are being applied.
6. Always comply with the Instruction for use of the nerve stimulator being
used.
7. For stimulating cannulas and catheters: Do not use devices that emit elec-
tromagnetic radiation near the patient. This avoids any electromagnetic
interaction.
further warning indications:
Caution: Sharp object warning. The device or device components may,
1.
depending on the type of tip, have sharp edges or tips. Various infec-
tious pathogens can be transmitted if a stab wound occurs. The most
relevant ones in practice are the human immunodeficiency virus (HIV),
the hepatitis B virus (HBV) and the hepatitis C virus (HCV).
2. You must routinely take general precautions for handling blood and bodily
fluids when using and disposing of the device, due to the risk of contact
with blood-borne pathogens.
3. Please note that the continued use of a device of the same type must be
assessed cumulatively as described in the legislation on medical devices,
even after the device has been exchanged or replaced.
4. Avoid build-up of fluid film between the catheter and ClampingAdapter
(e.g. through fluids on gloves). Fluids on the proximal end of the catheter
can affect the holding force and result in disconnections and/or leakage.
Sequence of use
Placement of the cannula (single shot)
1. Perform skin disinfection and cover puncture area with a sterile fenestrated
surgical drape (aperture drape), local anaesthesia.
2. Perforating incision (optional: lancet, etc.)
3. Advancement of the cannula under the skin.
4. Determination of the position of the cannula.
5. Anaesthetic may be administered as soon as the exact localization and the
fixation of the cannula has been completed.
Catheter placement (continuous anaesthesia)
1. Place the catheter container on the cannula hub.
Make sure when you perform the puncture that the opening of the cannula is
pointing in the direction in which the catheter will later be inserted.
2. Push the catheter with the marked end into the target area until it has
reached the required depth.
