Ventricular Drainage System
Sterile For Single Use Only
NL850-500V
Description
The Ventricular Drainage System, Model
NL850-500V (see Figure 1), provides a
sterile fluid path for the drainage of
cerebrospinal fluid (CSF) from an
intraventricular catheter to a collection
bag. System components facilitate
ventricular drainage, fluid injection, CSF
sampling and intracranial pressure (ICP)
monitoring when used in conjunction
with Camino Ventricular Pressure
Monitoring Kits.
The 4-way stopcock provides control of
the CSF drainage system. By turning the
stopcock to various positions, you will
be controlling the direction of the fluid
flow.
The collection bag is calibrated to
provide approximate volumetric
measurement of the fluid collected.
Integral with the collection bag are a
50 ml rigid drip chamber, 30 cm H O
2
and 20 mmHg height scales used for
positioning the collection bag. The
proper placement is critical, as the
height of the bag affects the ICP . A
removable 1-way check valve is located
on the bag side of the 4-way stopcock.
Exiting the bottom of the collection bag
is a tube with clamp and self-sealing
injection/sampling port.
Indications
The major indication for external
drainage is the management of
hydrocephalic shunt infections. If an
internal shunt is not indicated, treatment
of other cerebral conditions such as pre-
operative or post-operative pressure
STERILE EO
monitoring may also require external
drainage of CSF to control increased
intracranial pressure.
Contraindications
This device is not designed, sold, or
intended for use except as indicated.
Instructions for Use
Alignment
• The ICP is controlled by the height of
the collection bag above the tip of the
catheter; therefore, proper placement of
the bag is critical.
• When using the cord for alignment,
secure the cord of the drainage bag to
an IV pole or other appropriate support.
Utilize the height scale on the bag to
maintain proper ICP . For example, to
maintain an ICP of approximately
15 mmHg, the 15 mmHg mark on the
height scale should be located at the
approximate level of the catheter tip in
the patient's ventricles.
• When using the pole clamp
(NL850 PC), attach the pole clamp to
the IV pole. Adjust the pole clamp height
so the extended pointer is located
approximately at the patient's ventricles
(the top of the patient's ear) and secure
in place. Then attach the bag to the pole
clamp by sliding the burette down
through the burette holder until it stops
(see Figure 1). Utilize the height scale
on the bag to maintain the proper ICP .
For example, to maintain an ICP of
approximately 15 mmHg, the 15 mmHg
mark on the bag should be aligned with

the pointer, which is approximately
at the same level as the patient's
ventricles. After alignment, ensure
the burette holder is locked in place.
It is critical that neither the patient
nor the collection bag be raised or
lowered accidentally. Height
changes should only be made by
qualified personnel on the orders
of the physician.
Set-Up
• Aseptic technique should be used
during set-up and use of the ventricular
drainage system.
• If desired, the 1-way check valve can
be removed from the system by
disconnecting the luer locks on both
sides of the valve. Then, re-connect the
tubing directly to the 4-way stopcock.
Note: The 1-way valve helps to control
the direction of the fluid flow and reduce
the chance of fluid backflow.
Priming
• The external portion of the Ventricular
Drainage System must be primed before
connection to the catheter. Using aseptic
technique, fill a syringe with sterile
saline. Before puncturing, the port must
be aseptically cleaned to prevent
possible contamination.
• Close the 4-way stopcock to the
extension tube and inject saline through
the 4-way stopcock injection/sampling
port. Prime the drainage tube until fluid
