Blood Pressure
Recorder
(non-invasive)
General
The BP RECORDER 58500 combines three main systems
l
pressure generation-pressure monitoring system
l
a pulse amplifier and
l
a thermal-array analog & digital recording unit
with
two auxiliary systems
l
pulse rate measuring and recording
l
microprocessor controlled functions to self diagnosis,
calibration, signal filtering, signal storage.
Instrument Description
Pressure is transmitted to the tail cuff; as soon the cuff
pressure exceeds the diastolic pressure and starts to nar-
row the tail artery, the amplitude of the recorder pulse
wave gradually decreases until the artery is completely
constricted (ischemic), the graph becoming a straight line.
This point indicates the maximum internal pressure of the
artery (
systolic pressure
) on the paper grid, on which the
actual pressure
of the system is
digitally printed in 10
mm Hg steps.
At the end of the recording a second pressure measure-
ment can be started, with decreasing pressure. The sy-
stolic pressure is indicated, this time, by the return of the
pulse tracing.
The animal
pulse rate
can be assessed in real time by a
pulse rate counter which picks the signal from the pulse
transducer.
