natus Camino 110-4G Mode D'emploi page 4

PRECAUTIONS
• Extreme bending and/or kinks can impair
the performance of the Fiber Optic Pressure
Transducer. Exercise caution when handling
the Catheter.
• The catheter is designed for SINGLE USE
ONLY. DO NOT RESTERILIZE OR REUSE.
Camino 110-4G is supplied in a single use
package and is guaranteed to be sterile and
non-pyrogenic unless opened or damaged.
The catheter design incorporates a small
lumen and an intricate sensor that is likely
to make it difficult to assure removal of all
contamination. Additionally, reprocessing
is likely to damage the delicate sensor that
may result in impaired function (e.g. no or
inaccurate measurements).
• Use aseptic
procedures.
• Maintain the insertion site with regular, met-
iculous redressing using aseptic technique.
• Do not attach anything to transducer air vent.
Vent must remain open for proper operation
(Figure 1).
CAUTION
Federal (U.S.A.) law restricts this device to sale
by or on the order of a physician.
INSTRUCTIONS FOR USE
The Camino catheter is used with the Camino
intracranial pressure monitor (models V420/420,
MPM, SPM, CAM01, or CAM02). For Camino
monitor set-up and use, refer to the appropriate
Camino monitor Instructions for Use.

CATHETER PREPARATION PRIOR
TO INSERTION
Remove the Camino Catheter from its sterile
package and firmly attach the transducer
connector to the preamp connector (Figure 2).
If the Camino display does not read zero after
a short system self check display, use the tool
from the catheter kit to turn the zero adjustment
on the bottom side of the transducer connector
until the Camino display reads zero (Figure 3).
To measure post-craniotomy subdural pressure,
first prepare the Camino transducer-tipped
catheter as previously instructed. Choose the
burrhole through which the Camino catheter will
enter and notch the corner. After the catheter
has been zeroed, position the tip of the catheter
within the trocar's guide tube, and use the trocar
to tunnel the catheter under the scalp, toward
the craniotomy site. Then remove the trocar.
Place the tip of the catheter on the brain tissue,
under the dura, opposite the notched burrhole.
Locate the tip under the intact skull, to isolate it
from local pressures which may be caused by
2
technique throughout
movement of the bone flap. (Figure 4).
Close and suture the dura using standard
neurosurgical procedure. Position the catheter
through the notched burrhole, and replace the
bone flap. Suture around, not through, the
catheter, and secure it to the scalp.
After the site has been dressed, secure the
preamp connector to the patient to protect the
fiberoptic catheter.
IT IS RECOMMENDED THAT THE CATHETER
BE DISCONNECTED FROM THE PREAMP
CONNECTOR WHEN THE PATIENT IS MOVED.
THIS WILL NOT AFFECT CALIBRATION.
CONTINUOUS PRESSURE
MONITORING
Since the Camino Catheter has a miniaturized
transducer at the distal tip, it requires no fluid-filled
system. Thus, the need for an external transducer,
pressure tubing is eliminated. As a result, pressure
may be monitored continuously without recalibration.
