An Overview
This chapter gives an overview of the
instrument to help you understand the system.
Description of the Device and Intended Use
General
This is an instrument providing an automated system for measuring the Flow Rate, Volume
Delivered and Occlusion (Stall) Pressure of Infusion Devices with various methods of
delivery.
It is used to verify the performance of Infusion Devices and provides facilities for
displaying results on the instrument’s LCD, saving test results for subsequent printing and /
or downloading to a PC.
Model Variations
There is one basic design which has provisions for one, two, three or four independent
channels of measuring transducers within a common housing, providing options for testing
up to four Infusion Devices simultaneously with one instrument.
Operational Modes
The unit can be used in a stand alone mode displaying results on the LCD and can
subsequently print saved test results via a printer port and / or download saved test results
to a PC via an RS232 port.
The unit may also be linked to, controlled by and display results via a PC using an external
program, such as HydroGraph™ available from Fluke Biomedical.
Volume & Flow Measurement
Volume and flow measurements are achieved by using a calibrated burette and opto-
sensors within each measurement transducer to accurately monitor the volume and time of
the meniscus passing up the burette. This data is processed to
provide Average Flow Rates,
Bolus and Total Volume Delivered and Timing measurements.
Occlusion & Back Pressure Measurement
A pressure transducer within each transducer performs pressure measurement. The output
of the pressure transducer is fed to a conditioning amplifier then processed and the results
displayed on the LCD and, if connected, on the PC screen. The user has the option to
display Occlusion Pressure in psi, mmHg or kPa whereas Back Pressure measurement is
set to default to mmHg only.
