iv. SP430 Module: Directions For Use
A. Transonic Scisense Pressure Catheters
Unpack the Catheter from its original packaging (keep the
packaging for storing the Catheter after use). Care must be
taken to avoid kinking the Catheter tubing. Be careful not to
apply direct pressure to the sensor membrane.
1) In order to minimize signal drift, immerse the sensing tip in
saline (i.e. a saline lled syringe) and allow a warm up time
of 30 minutes while preparing the animal for surgery.
2) Connect the Catheter to the channel 1 input using the
supplied HDMI cable.
3) Immediately before using the Catheter, the pressure signal offset must be adjusted to zero using the
balance control knob for channel 1 on the SP430 Module (see “Transducer Calibration Check” on page
29 for directions). Use caution not to bump the balance knob once adjusted.
4) If using a second Pressure Catheter, follow the directions above using channel 2.
5) Make sure the Module is in [MEA] mode prior to taking measurements.
B. Dual Pressure Catheters
A Dual Pressure Catheter must be plugged into channel 1 to provide two pressure measurements instead
of using two separate Catheters. The primary pressure will be output as “Pressure 1” and the secondary
pressure value will be output as “Pressure 2”. NOTE: With Transonic Scisense Dual Pressure Catheters the
distal (tip)pressure sensor is primary and the proximal pressure sensor, secondary.
● If a second Catheter is plugged into channel 2 it will override the secondary pressure value of the rst
Catheter. NOTE: There will only be two pressure outputs regardless of the number of transducers.
● If a Dual Pressure Catheter is plugged into channel 2 it will only provide a single pressure signal
regardless of the presence of a Catheter in channel 1. The primary pressure signal will be output as
“Pressure 2.”
● If Dual Pressure Catheters are plugged into both channels then the primary pressure signal from each
Catheter will be output as the respective pressure signal.
C. Catheter Cleaning & Care
ALWAYS CLEAN PRESSURE CATHETERS IMMEDIATELY AFTER USE.
FAILURE TO PROPERLY AND PROMPTLY CLEAN CATHETERS MAY CAUSE SENSOR FAILURE
AND VOID ANY AND ALL WARRANTIES. DO NOT USE ULTRASONIC CLEANERS FOR THE CATHETERS.
For complete cleaning instructions see “Catheter Cleaning & Disinfecting Guide” provided with each Catheter.
1) Immediately after use, immerse the Catheter in distilled water or saline.
2) Soak the Catheter in a pH neutral enzymatic cleaning solution (i.e. Endozime
®
).
3) Optional: Disinfect in Cidex
®
(Not: Cidex
®
7, Cidex
®
Plus or Cidex
®
PA) or similar solution. Do not use
glutaraldehyde solutions containing surfactants or solutions containing hydrogen peroxide.
4) Rinse the Catheter by soaking in distilled water to remove all traces of cleaning agents.
5) Dry the Catheter by placing on a paper towel or gauze. Do not air dry or use alternative drying methods.
NOTE: Never apply direct pressure to the pressure sensor membrane.
