 The
INVOS Cerebral Oximeter, Preamplifier and
SomaSensors
The INVOS Cerebral Oximeter system monitors
changes in the regional oxygen saturation, or rSO2,
within a sample of hemoglobin in the cerebral cortex. Changes in
INVOS values reflect changes in the critical balance between arterial
oxygen delivery and cerebral consumption.
· Continuous and noninvasive
· Risk free to clinician and patient
· Not pulse, pressure or temperature dependent
· Pre-calibrated and ready to use in just 30 seconds
· Compact and portable
The INVOS Cerebral Oximeter provides noninvasive, continuous and
direct information on regional cerebral oxygen saturation. The measurement
takes place in real time, providing an immediate indication of a
change in the critical balance of oxygen delivery and oxygen consumption.
The screen displays the rSO2,
trend data, system status, alarm limits, rSO2
limits, date and time. Also displayed are menus for default parameter
changes, alarm messages and data trending rate. Menu keys allow
the operator to change available options as desired.
 Alarm
notification, consisting of visual and audible indicators, appears
immediately following display of a saturation value outside of the
user-adjusted high or low limits. An on-screen trend (graph) display
is updated every 30 or 60 seconds (user selectable). The trend can
be adjusted to display variable lengths of stored data from one
hour to 24 hours. Data can be retrieved by using the RS-232 port
via a null modem cable or disk drive. Both
the null modem cable and disk drive are available for purchase.

Preamplifier Cable
The 15-foot long Preamp cable attaches
to a portal on the front panel of the Cerebral Oximeter. The Preamplifier
provides an electrically isolated connection for the SomaSensor.
At the other end of the Preamp is the patient connection to attach
the bilateral reusable cable and SomaSensors.
top
SomaSensor®
 The
SomaSensor, a disposable, non-sterile transducer, is capable of
producing and detecting near infrared light using patented optical
design characteristics, converting this data to electrical signals
and relaying them to the INVOS system. A SomaSensor is applied to
the forehead with an integrated medical-grade adhesive.
 The
SomaSensor is designed for single use only and may not be reused.
(Reuse of the SomaSensor may cause inaccurate readings, erratic
readings, or no readings at all.) There are different SomaSensors
for adult, small adult and pediatric patients.

 Bilateral
Reusable Sensor Cable
The sensor cable is intended for multiple
use and should not be discarded. The Bilateral Reusable Sensor Cable
connects the SomaSensors to the Preamp.

INVOS Cerebral Oximeter Accessories
The following accessories can also be purchased
for use with the
INVOS system:
 |
Disk Drive
A disk drive allows data from the
INVOS system to be transferred and stored on an IBM formatted
DS/HD 3.5" floppy disk. Clinical information is then available
for future review and archiving. The data can be plotted in
a variety of formats. Use only a Somanetics supplied disk
drive with the INVOS system.
|
 |
Portable Stand
A portable rolling stand is available, providing flexibility
in placement of the INVOS Cerebral Oximeter in your facility.
The base is 24" in diameter, made
of die cast aluminum and polished and buffed with a scratch
resistant finish. The five point casters are four inches in
diameter, non locking with full swivel. The portable stand
height, from floor to mounting plate, is 47", with a 55" height
overall. A utility basket (12" wide, 8" deep and 12" high)
is included. Easy assembly.
|
 |
Field Test Device
The field test device allows for
functional testing of the INVOS system. Only a Somanetics
supplied field test device should be used with the INVOS Cerebral
Oximeter.
|
 |
Travel Case
A protective equipment case to safely transport your INVOS
Cerebral Oximeter monitor and component parts is available.
The padded case, made of two-ply extra firm density foam with
polyethylene reinforcements, comes with a detachable, adjustable
shoulder strap and an outside zippered pocket. Attractive
and sturdy.
