Warnings
- Do not use in the presence of flammable gases such as anesthetic agents.
- Do not use in the sterile fi eld unless additional barrier precautions are taken.
- Do Not:
- immerse in any liquid,
- use solvent cleaner,
- use high-temperature sterilizing processes (such as autoclaving),
- use E-beam or gamma radiation sterilization.
- Do not use on the eye or scrotum.
- Do not dispose of batteries in fi re as this can cause them to explode.
- Do not attempt to recharge normal dry-cell batteries. They may leak, cause a fi re or even explode.
- This product contains sensitive electronics, therefore, strong radio frequency fields could possibly interfere with it. This will be indicated by unusual sounds from the loudspeaker. We recommend that the source of interference is identified and eliminated.
- Any equipment connected to RS232 interface must be compliant with IEC60601-1:2005.
- Connect headphones only to the headphone socket.
- Dopplex Dopplers are screening tools to aid the healthcare professional and should not be used in place of normal vascular or fetal monitoring. If there is doubt as to vascularity or fetal well-being after using the unit, further investigations should be undertaken immediately using alternative techniques.
Patient Applied Parts
As defined in IEC60601-1:2005, the patient applied parts of the Dopplex
Dopplers are the ultrasound probes.
Acoustic Safety
Continuous wave Doppler ultrasound instruments such as the MD2/SD2 have been
used extensively for medical diagnosis in the United States for over 25 years.
Throughout this period, there have been no reports of adverse effects to
patients or instrument operators at the acoustic intensities recommended for
diagnostic use. Despite this highly favorable safety experience, available
data are not conclusive and the possibility remains that unwanted biological
effects might be identified in the future. Authorities, therefore, recommend
that ultrasound procedures be performed in accordance with the “ALARA”
principle, which states that the energy delivered to the patient should always
be kept As Low As Reasonably Achievable. With the MD2/SD2, the transmitted
acoustic power is fixed and cannot be adjusted by the operator. Therefore, the
user can best observe the ALARA principle by ensuring that each examination is
medically indicated and by limiting the duration of the study to the extent
appropriate for the clinical objectives. Acoustic intensity data (ISPTA.3) for
probes available for use with the MD/SD2 are summarized in the following
table. The values cited are based on measurements in water using a calibrated
hydrophone and are stated as the estimated derated intensities. The derated
intensity constitutes the most biologically relevant parameter available since
true determinations of actual absorbed dose in tissue would require invasive
measurement techniques. The derated intensity is therefore calculated
mathematically using a derating factor consisting of a constant (the assumed
attenuation coefficient) and allowing for the frequency of the probe and the
distance from the probe face to the hydrophone. The calculated derated
intensity values for the MD/SD2 compare very favorably with previously
reported acoustic safety data for Doppler ultrasound instruments and are
appropriate for all clinical applications recommended in this manual. As the
operating mode of the Dopplex range of probes is continuous wave, ISPPA
figures are not applicable.

Delivery Inspection
Huntleigh takes every precaution to ensure that goods reach you in perfect condition. However, accidental damage can occur in transit and storage. For this reason we recommend that a thorough visual inspection is made immediately the unit is received. Should any damage be evident or any parts missing, ensure that Huntleigh or your distributor is informed at once. -
Storage
Should the unit not be required for immediate use, it should be re-sealed into its original packing after carrying out the initial delivery inspection, and stored under covered conditions at a temperature between +14°F to +104°F (-10°C to +40°C), and relative humidity of 10% to 93% non-condensing.
Battery Insertion / Replacement
Note: Remove the battery if the unit is not likely to be used for some time.

Product Labelling
Operation
Refer to diagram on page 3 for Doppler Measuring sites and Recommended Probes.
To connect the probe, align the arrow on the connector with the slot on the
probe and push firmly. To disconnect the probe, pull the connector sharply. DO
NOT pull the cable.
Note: During use, an automatic noise reduction feature operates on low-
level signals to improve sound quality.
Coupling Gel
Use water-based ultrasound gel ONLY.
Vascular Mode
The Multi Dopplex II/Super Dopplex II Dopplers (MD2/SD2) will select vascular
mode when a vascular probe is connected to the control unit.
Vascular Probes
Five probes are available for vascular examinations:
VP4HS | 4MHz ±1% for deep lying vessels |
---|---|
VP5HS | 5MHz ±1% for deep lying vessels and oedematous limbs |
VP8HS | 8MHz ±1% for peripheral vessels |
VP10HS | 10MHz ±1% for specialist superficial applications. |
EZ8 | 8MHZ ±1% “Widebeam” for peripheral vessels. |
In this mode, bi-directional blood flow rate and direction are indicated on bar graphs (4 levels in each direction) and blood flow is audible in the loudspeaker. Probe frequency is displayed together with the bar graphs.
Clinical Use
Apply a liberal amount of gel on the site to be examined. Place the probe
at 45° to the skin surface over the vessel to be examined. Adjust the position
of the probe to obtain the loudest audio signal. High pitched pulsatile sounds
are emitted from arteries while veins emit a non-pulsatile sound similar to a
rushing wind. For best results, keep the probe as still as possible once the
optimum position has been found. Adjust the audio volume as required.
Waveform Recording (MD2 only)
Separated waveform outputs are provided in analogue and digital formats.
Analogue signals are provided for connection to a single-channel chart
recorder giving a combined bi-directional waveform, or to a dual-channel
recorder for separate forward and reverse flow waveforms. (Pin-out details on
request). Digital signals are provided via the RS232 port for printing
separate waveforms on a Dopplex Printa II or for communicating with Dopplex
Reporter software package.
Cal Function
The baseline and sensitivity of the chart recorder can be set up using the Cal
function. This generates a zero velocity baseline and a sequence of
bidirectional pulses as shown below:
Gain Control
To cope with the wide variety of signals detectable using your MD2/SD2, gain
control allows you to optimise the bar-graph display and increase the height
of the waveforms. Using the Mode button on the MD2 (Gain button for SD2), gain
can be set to x1, x2, x4, x8.
Connection to Printa II™ (MD2 Only)
Hard copy printing is automatically selected when the plug of the interface
buffer box is inserted into the RS232 socket on the top panel of the MD2.
Printing is then initiated by using the Start/Stop button.
Connection to Software (MD2 Only)
The MD2 can be connected to the Reporter Software Package, via the RS232
interface. Dopplex Reporter software package is available as an accessory.
Communicating is then initiated by using the Start/Stop button.
Obstetric Mode
IMPORTANT! READ THIS SECTION BEFORE USING YOUR Multi Dopplex.
- Although the Multi Dopplex will calculate the rate as early in pregnancy as fetal pulse signals of good quality can be elicited, generally from about the 9th or 10th week after the last menstrual period, fetal heart rhythm may not be sufficiently stable to permit accurate rate computation until well after the first trimester.
- Similarly, no attempt to apply non-stress test (NST) interpretation criteria should be made until after the 25th week of gestation, when neurological development is usually sufficient to obtain a reactive pattern. To be considered reactive, two accelerations at least 15 bpm in amplitude and at least 15 seconds in duration should occur in a 10 minute period.
- If the fetus is found to be non-reactive using the Multi Dopplex hand-held sampling technique, consideration should be given to repeating the test using a conventional fetal monitor.
- The Multi Dopplex is suitable for intermittent auscultation during the intrapartum period, but not recommended for long-term intrapartum monitoring, where Cardiotocographic equipment, including contractions measurement capability should be employed.
Obstetric mode is automatically selected when an obstetric probe (OP2HS/ OP3HS) is connected.
Obstetric Probes
Two probes are available for obstetric examinations:
- OP2HS 2MHz ±1%
- OP3HS 3MHz ±1%
In this mode, MD2 provides fetal heart rate (FHR) display with 3 operating modes, and outputs FHR for printing on the Printa II. The SD2 in obstetric mode provides audio only.
Clinical Use
- Apply a liberal amount of gel to the abdomen. Place the faceplate of the probe flat against the abdomen above the symphysis pubis. Adjust the probe to obtain an optimum audio signal ideally by angling the probe around. Avoid sliding it over the skin.
- In early pregnancy a full bladder may improve sound detection. In later pregnancy the best signals are generally located higher on the abdomen. The fetal heart sounds like a galloping horse at approximately twice the maternal rate. A wind-like sound is heard from the placenta.
Standard Mode – MD2 Only
In this mode the FHR, averaged over 4-heart beats, is displayed on the 3-digit
readout. The LCD displays an outline heart symbol.
Smoothed Mode – MD2 Only
This mode is used to obtain more stable heart rate readings. In this mode, FHR
is averaged over 8 beats. The LCD displays a solid heart symbol.
Manual Mode – MD2 Only
This mode is used when a fetal heartbeat is audible in the loudspeaker or
headphones but, due to noise or a low signal level, the MD2 cannot reliably
calculate the heart rate. In this mode, the heart rate can be manually counted
over a period of 10 audible heartbeats (see below). The MD2 will automatically
calculate and display the derived FHR on the LCD. The LCD displays a clock
symbol.
Mode Selection
Press the Mode button to select mode.
Use of Manual Mode
- Press and hold Start/Stop button and immediately count the audible heartbeats, counting the first beat as the button is pressed. The LCD displays the flashing clock symbol and the FHR reading is shown as three dashes.
- Release the Start/Stop button immediately on the count of 10 (i.e. After nine-beat intervals). The MD2 will automatically calculate the derived FHR averaged over the 10 beat period and display the result. This rate value is retained until the measurement is repeated or the unit is switched off. If the button is held for a period less than about 3 seconds the display will clear the previous rate value and reset.
Connection to Printa II™ (MD2 Only)
Hard copy printing is automatically selected when the plug of the interface
buffer box is inserted into the RS232 socket on the top panel of the MD2.
Printing is then initiated by using the Start/Stop button.
After Use
- Press and release the On/Off button. If you forget to switch the unit off, it will automatically shut off after 3 minutes.
- Refer to the cleaning section before storing or using the unit on another patient.
- Store unit together with the probe and accessories in the soft carry case provided.
