This noninvasive blood
pressure test system measures blood pressure on rats
and mice via the tail cuff method using the photoelectric
tail cuff principal supplying data that is excellent
correlation to direct Cannulation as well as telemetry.
A three channel systems allows testing of up to three
animals at a time and supplying systolic, mean and
diastolic measurements.
IITC’s noninvasive
blood pressure system for mice and rats requires
minimal warming of rats and mice. The rodents should
be warmed to an ambient temperature of 30 deg. C
for rats and 32 deg. C for mice, which is well below
the thermostress level (see NIBP Intro. page). Not
like other manufacturers who require high temperatures
resulting in heating the animal. Once the animal
is heated as high as 38 deg. C in other systems the
animal now is at a thermostress level as well as
there being a high chance of death since the animal
is literally being “heated to death!”
A unique feature of
IITC’s amplifier is the artifact filter, which
minimizes the breathing and movement artifacts, enabling
the user to pick out the endpoints easily. Others
claim that this feature is not required with their
systems. This is a unique feature from IITC since
we know that animals move and their breathing is
picked up by our tail cuffs and amplifiers. IITC’s
cuffs are so sensitive picking up blood pressure
signals; a filter has been added to assure the user
knows the difference between “true blood pressure” and
other types of artifacts which can appear on a
recording. Others do not have this feature since
their equipment is not as sensitive. Their recordings
do not know if they are viewing blood pressure,
breathing, movement or any other type of artifacts
that could appear during tail cuff studies.
The output on the Model
29-SSP is analog. The instrument has separate outputs
for single channel and dual channel (superimposed
and split) recording. The typical pulse amplitude
is 100 mV to 1 V. The pressure amplitude is adjustable
from one to five volts at 300 mmHg. If systolic and
heart rate are desired, a single channel chart recorder
(Model 38L) is sufficient. If the Mean and Diastolic
are the desired reading then a dual channel chart
recorder is recommended (Model 45L) or the IITC software
package (Model 31).
The three channel warming
chamber (temperature adjustable between 25 to 34
deg. C) which house’s the animals in a constant
temperature environment critical to tail cuff blood
pressure measurements. Clear acrylic allows complete
visuals. The aluminum base holds a “whisper” fan,
producing low level
“white noise” which comforts the animals. The back and front walls
have vent holes for exit of air and sensor cables. Tubing ports are provided
for the inflating connection.
IITC’s Model
303SC chamber with built-in scanner is a simplified
scanner that is built into the metal base. This
chamber has a signal connection to the input of any of
the IITC blood pressure amplifiers. The IITC sensors
can be plugged into their respective jacks on the
chamber side. The air to the cuffs is also scanned
by a manual three stage manifold to avoid edema
effects on the extremity. A manual system with this chamber
becomes turnkey ready for up to three animals.
No Heating
pads or any other type of additional heating accessories
are required with this system.
Sensors work off the
photoelectric tail cuff built into one small compact
unit, the other tail cuffs on the market are separate
inflation and detection pieces which prevents attaining
accurate blood pressure measurements from the animal.
Animals are restrained
in the supplied restrainers and the tail cuff is
attached to the end plate of the restrainers. This
assures accurate measurement since the cuff is stationary
and not moving as in other manufactured cuffs on
the market.
System Includes:
A three channel IITC noninvasive blood pressure with manual inflation system
contains an amplifier, the warming chamber with built-in scanner is used
to assure that uniform warming of the animals occurs during the test period.
Three animal restrainers and three tail cuffs (sensors) are supplied for
the appropriate weight range that is supplied. The SP-1 Accessory package
is supplied with spare cuff liners, o-rings, Tygon tubing for port connections,
nylon screws for attachment of sensors to restrainers and a bulb and pressure
gauge as well.
