cigii P612 Ultrasonic Fetal Doppler

Product Information Ultrasonic Fetal Doppler

The P612 ultrasonic fetal doppler is a hand-held, battery powered doppler fetal heartrate detector. It is intended to detect and display fetal heart rate, and it is used by healthcare professionals in hospitals, clinics, communities, and homes for singleton pregnancies after 16 weeks gestation. The device is not intended for treatment and it is not explosion-proof. It cannot be used in the presence of flammable anaesthetics. The batteries should not be thrown in fire as this may cause them to explode. Normal dry-cell batteries should not be recharged as they may leak and cause a fire or even explode.

Components of the Device

• Ultrasonic Fetal Doppler
• Battery Cover
• Gel
• User Manual

The following components are including with the package, make sure all the components are complete when you open your new purchase

Battery Installation

1. Open the battery cover located on the back of the device.
2. Insert the two 1.5V AA batteries into the battery compartment following the correct polarity (+/-).
3. Replace the battery cover.

CAUTION Use only 1.5V”AA”alkaline batteries with the device.

1. STEP1-Press the indicator on the battery cover and slide the cover off in the direction of the arrow.
2. STEP2-Install two ”AA” size batteries so the +(positive) and –(negative) polarities match the polarities of the battery compartment as indicated.
3. STEP3- Close the battery cover.

Taking a Detection

1. Apply gel on the probe of the device.
2. Turn on the device by pressing and holding the power button until the device beeps and the LCD screen turns on.
3. Place the probe on the abdomen in the region of fetal heart, and move it slowly until it detects fetal heart rate.
4. The detected fetal heart rate will be displayed on the LCD screen.
5. When done, turn off the device by pressing and holding the power button until the LCD screen turns off and the device beeps.

Before detection
Check whether the device is in good condition and whether there is obvious damage that may affect the safety of pregnant women or the performance of the device; if any damage is found, please stop using it immediately and replace the damaged parts.

Detection Procedure
Follow the steps below for fetal heart rate detection:

1. The pregnant woman lying on bed;
2. Apply an appropriate amount of couplant to the acoustic surface of the ultrasound fetal Doppler;
3. Turn on the power switch;
4. Touch the pregnant woman’s abdomen to determine the position of the fetal;
5. Place the device on the pregnant woman’s abdomen and move or tilt the device slowly within the range of the fetal until hearing clear and rhythmic fetal heart sounds and see a stable fetal heart rate value;
6. After the detection, turn off the device first, and then use a clean soft cloth or paper to wipe off the remaining couplant on the surface of the pregnant woman’s abdomen and the ultrasound head of the device.

CAUTION Do not mistake maternal heart rate as fetal heart rate.

CAUTION  Do not take gloves to operate the buttons. If there is water, couplant and other substances on the surface of the fingers, please clean them first, otherwise the test results will be affected.

Look for the fetal heart rate
Since the fetus moves at any time in the abdomen, the position of the fetal heart is not fixed. You can refer to the uterine fundus height of the following different pregnancy cycles to determine the approximate range of the fetus:

• At the 12th week of pregnancy, the height of the uterine fundus is 2-3 transverse fingers above the pubic symphysis (about 2-3cm).
• At the 16th week of pregnancy, the height of the fundus is between the navel and the pubic bone.
• At the 20th week of pregnancy, the height of the fundus of the uterus is 1 finger below the navel (about 1cm).
• At the 24th week of pregnancy, the height of the fundus of the uterus is 1 finger above the navel (about 1cm).
• At the 28th week of pregnancy, the height of the fundus of the uterus is 3 fingers above the navel (about 3cm).
• At the 32th week of pregnancy, the height of the fundus of the uterus is between the navel and the xiphoid process.
• At the 36th week of pregnancy, the height of the fundus of the uterus is 2 fingers below the xiphoid process (about 2cm).

See the position picture of the fetal heart below:

Care and Maintenance

• Clean the probe after each use with a soft cloth or tissue.
• Store the device in a dry and clean place.
• Replace the batteries when low to ensure accurate detection results.

To keep your ultrasonic fetal doppler in the best condition and protect the unit from damage, follow the directions listed below:

Maintenance

• Before each use, the device must be checked whether has obvious damage that could affect the safety of pregnant women or the performance of the device. If damage is found, make necessary repairs or replacements.
• The accuracy of the fetal heart rate is controlled by the device and cannot be adjusted by oneself. If the fetal heart rate result is not reliable, use other methods such as using a stethoscope to verify, or contact your local agent or manufacturer for assistance.
• The device is a precision instrument and must be handled with care.the excess couplant on the ultrasonic probe must be wiped off after the instrument is used.
