Here are a few pieces of Test Equipment used daily by BMETs.
Click on the thumbnail for a larger picture. The appearance of a
particular piece of equipment does not mean BMET endorses the product, it just
happens to be what this BMET is using at the present time. BMET does not
receive any compensation from any manufacturer for listing their product on
these pages!
This is a Dynatech Nevada 231D
Safety / ECG Analyzer. This device is used daily by BMETs for
performing an electrical safety inspection on a piece of medical equipment on
inventory and after making a repair, to insure the unit passes electrical
safety. The results are then recorded on a sheet of paper called a pm
sheet which has the control number for that specific piece of equipment along
with possibly model, serial, locations entry's as actual numbers or pass /
fail. Many shops today are going paperless, and the safety analyzers they
use are fully automatic and inventory numbers and test results are bar coded and
uploaded to laptops automatically. A ballpark figure for this device is
approximately $1,025.00.
This is a Dynatech
Impulse 3000 defibrillator analyzer. It is digital and upon discharge of a
set of defibrillator paddles onto the large silver disks you see on the machine,
you get an energy readout in joules. The function of this particular unit
for testing defibrillators is: that it measures the energy delivered to
the load ( which is 50 ohms, approximating that of the human body ).
It also
performs a Cardioversion test by simulating a heartbeat at the ECG leads and
measuring the delay time from the R-wave peak to the firing time of a
synchronized defibrillator. The ecg signal is also present on the paddle
contact plates for pickup by the defibrillator directly through the
paddles.
It also outputs a voltage attenuated signal of the defibrillator
pulse in real time for viewing on an oscilloscope. Finally, this base unit
plays back the defibrillator pulse at a slow speed out the ECG leads for viewing
on a cardiographic strip chart recorder.
This particular unit has the
capability of having additional options, which we have, that plays a series of
waveforms out the ECG leads suitable for testing the performance of ECG
monitors. It also plays a series of heartbeats simulating ECG waveforms
including several rates and arrhythmias. In addition, it can play a
special series of ECG waveforms which interact with the defibrillator pulse for
training purposes (EMT-D) including ventricular and atrial fibrillation and the
result of defibrillation.
It can also run automatic sequences of tests
which may be custom programmed for specific defibrillators an which may include
energy level tests with programmed limits, maximum energy test which also
measures the charge time for a full scale pulse, and cardioversion tests.
The test results may be printed via the RS-232 output, formatted as a one page
report. A ballpark price on this unit is $1,230.00.
 The
medSim 300B Patient Simulator by Dynatech Nevada. Now you know how they
put that heart rate upon the monitor screens in all your favorite doctor and
emergency medicine shows.
With a unit like this, loaded with options, there is very little that can not be
displayed in almost any scenario from normal to life threatening arrhythmias.
This high performance simulator generates the following physiological
simulations:
* ECG waveforms
* Respiration
* Four dynamic blood pressure channels,
and
* Dynamic and static temperature.
Additionally, there are three optional features available, which BMET uses:
* Option 1 (Cardiac Catheterization,
Fetal/Maternal ECG with Intrauterine
Pressure, and Intra-aortic Balloon Pump)
* Cardiac Output Option, and
* The medSim Controller Option.
The ballpark price for this unit is $1,435.00 To include the Option 1
package, you may have to add another $670.00
 The
Dynatech Nevada Model 454A Electrosurgical Analyzer. This unit may have
been upgraded at this writing, but this particular unit used by BMET performs
very well.
The Model 454A Electrosurgical Analyzer is an instrument that analyzes the
performance of an electrosurgical unit (ESU). It has been designed to test
ESUs in use by physician in their office or at the hospital. The purpose
of this instrument is to measure and report specific ESU safety and performance
parameters.
The Model 454A is specifically intended to measure output parameters
of an ESU. It is a microprocessor based instrument utilizing a precision
thermal converter to make true RMS current measurements. In addition, it
has a peak detection circuitry. This circuitry provides a method to
determine peak to peak voltage and crest factors in electrosurgical instruments.
A ballpark price for the Model 454A Electrosurgical Analyzer is $3,600.00
 The
NETECH PMT 100 External Pacemaker Analyzer.
The PMT 100 is an advanced microcontroller based, compact, high performance
external Pacemaker tester designed for accurately testing almost all types of
external pacemakers, both invasive and non-invasive (Transthoracic). It is
menu driven and simple to operate. All the functions are set from a 2 line
16 character LCD display and a key pad with 8 tactile keys. Using state of
the art technology, PMT 100 provides superior accuracy and performance.
To achieve its excellent price, performance ratio, PMT 100 employs one of the
latest microcontrollers running at 11.0592 MHz. PMT 100 has comprehensive
test ranges, accurately measures and displays amplitude, rate, energy and pulse
width of the pacing pulse as well as demand sensitivity tests, refractory period
and susceptibility to 50/60 Hz interference.
The above listing of equipment is just a minuscule sampling of test equipment
used by BMETs everywhere. To set up a small 2 man shop that has inventory
in Anesthesia, Birthing Centers, Med Surg, ICU, Emergency Department, Telemetry and Physical Therapy, easily
starts at 30K. In addition, the tool kits w/fluke 80 series with Cal Data
from Jensen will take you to almost a thousand apiece. Then lets not
forget starting wages for a BMET with 5 years experience is approximately $25.00
per hour in a hospital setting on the East Coast.
 Simulators to test Fetal Heart Rate Monitors like the one pictured cost
approximately $1,300.00 with appropriate cables for your specific FHRM.
 The
digital Strobe used to give us the RPM of a centrifuge costs approximately
$750.00
 This
great tachometer that I use for measuring mph (though it is capable of measuring
16 different functions) of a treadmill sells for approximately $620.00
This single piece of equipment has made Stress Test System / treadmill PM and repair extremely
accurate and cost effective.
 
   
There are many more pieces of equipment that I do not have pictures of that
could go here, such as the portable benches we push around the hospitals as we
do PM and repair, the carts we load our test equipment on when we go down the
road, the drawers full of fuses and connectors, wire and nuts we acquire over
the years of doing biomedical engineering work. There are additional
pieces of test equipment for breast pumps, suction units, T Pumps,
hypo-hypothermia units, Adult and baby Ventilators and CO2 analyzers.
There are also modern Blood Pressure, single and multiple channel infusion
device and SPO2 Testing Analyzers available.
