8 - 4 0070- 0-0704-02 Passport V Operating Instructions
WARNING: During procedures employing electro-cautery, use currently
acceptable procedures to minimize conditions of the
thermistor and lead wires functioning as an alternate path
for radio-frequency current to return to ground, causing
localized tissue burns. Procedures which may minimize risk
of electro-surgical burns are: keep both active and ground
electrodes of the electro-cautery system in close proximity
so that the temperature sensor is outside the radio-
frequency current field. Keep temperature monitor with its
associated cables separated from electro-cautery systems.
Unusual, fast artificial variations in temperature readings
may occur with concomitant applications of the electro-
cautery system.
WARNING: Sterile unless unit container is opened or damaged.
CAUTION: Single use.
Destroy after single use.
Do not resterilize.
Federal (U.S.A.) law restricts this device to sale by or on the
order of a physician.
8.3.2 Esophageal Stethoscope with 400 Series Thermistor Temperature
Sensor
Description (0206-03-0112-02, 0206-03-0118-02)
The esophageal stethoscope with temperature sensor is a disposable device which provides
for accurate measurement of core body temperature as well as transmission of heart and
lung sounds. Heart and lung sounds are transmitted across a thin cuff wall, through the side
and distal openings of the tube. Made of a special material which optimizes sound
transmission and remains both durable and flexible, the cuff maintains its integrity and
prevents secretion from entering the tube. For connection to any standard ear piece, a male
luer adaptor is attached to the proximal end of the esophageal stethoscope. The stethoscope
is 19 inches (48.3cm) long. The tube, the cuff and luer adaptor are made of lightweight, non-
toxic, implant tested material.
The temperature transducer is in the form of an electrically insulated “400” series thermistor,
which is permanently secured within the lumen of the esophageal stethoscope. The thermistor
is placed at the distal end of the tube. The accuracy of the thermistor is ±0.2°C in the range
of 5 - 45°C.
The assembly is disposable, single use only, and packaged sterile. It is available in sizes 12
and 18 French.
This device is intended for use with electronic temperature monitors accepting 400 series
thermistor sensors or equivalent that are equipped with alarms. To interconnect the probe
with the instrument, use cable part number 0012-00-0975.
Electrical leakage current of the device (sensor and esophageal stethoscope) when used with
monitor and cable, comply with IEC 601-1/EN 60601-1.
