Pregnancy Detector for Dogs

The Draminski Ultrasonic Pregnancy Detector determines pregnancy in dogs by locating amniotic fluid in the uterus.
The ultrasonic probe (sensor) held against the skin of the bitch, emits ultrasonic sound waves which are reflected by the amniotic fluid in the uterus of the pregnant bitch and return to the probe. The reflected sound is then measured and analysed by the instrument.
When an airless contact is made between the head of the probe and the skin, the instrument signals this with the diode (light) pulsing and a high-frequency acoustic (sound) signalling regularly once a second.
When pregnancy is detected however, the instrument signals this with a rapid pulsing
of the diode (light) and a corresponding rapid high-frequency acoustic (sound) signal.
The Draminski Ultrasonic Pregnancy Detector is ideally suited to pregnancy determination for individual breeders, large breeding & show kennels, veterinary surgeries and commercial organisations alike.
It is designed to be easy to use, maintain and provide rapid results with maximum accuracy.
Testing can be performed from 3 weeks after mating. However the optimal time for accurate diagnosis is between days 25 & 28, because of the enlargement of the uterus at this time and its movement slightly downward, closer to the peritoneum. Testing prior to day 25 is possible, but accuracy decreases due to insufficient amniotic fluid being present to reflect the ultrasonic waves. Testing after the optimal period is also possible.
Bitches vary in regards of weight and size for different breeds and thus the potentiometer (gain control) must be set to the particular position relevant to
the size of the bitch that is being tested.
For ease the potentiometer has been calibrated to show:
||For small bitches
||For medium size bitches
||For larger bitches
||For the giant bitches.
With usage, familiarity and experience, the gain control can be adjusted to suit the particular bitch, both in terms of breed type and actual size, so that an optimum setting is achieved to ascertain accurate results.

Immerse the head of the probe in the gel, oil, Vaseline, or other suitable medium and then hold the probe against the skin of the bitch at a position directed towards the horns of the uterus and ovaries. Move the probe in a sliding motion until you achieve a good airless contact, indicated by a steady flashing green pulse of light from the diode and acoustic signal 'beeping' at the same frequency. (Approximately once per second).
Test for pregnancy on both the left and right hand sides and commence scanning by moving the probe head around the general area, keeping the probe pressed against
the skin so as not to lose the airless contact.
When good contact is achieved, proceed with the scanning. As soon as the ultrasonic waves locate the amniotic fluid in the uterus and are reflected back, the green diode and acoustic signal will change to rapid pulsing at 4 to 5 per second to indicate pregnancy. If no pregnancy signal is achieved, (ie: the frequency of the flashing diode and the acoustic signal remains at once per second) move the probe by sliding against the skin surface whilst still maintaining good contact (confirmed by the continuance of the light pulse and sound at once per second) around the general area, initially moving slightly to the rear of the bitch and then moving forward always keeping at a 40 to 45 degree angle, directed towards the horns of the uterus and not vertical towards the spine and bladder.
In the 'wild' bitches tend to carry their offspring far higher-up, especially in the earlier stages of pregnancy, protected by their rib cage, thus it may be that the developing embryos in your bitch are sometimes found higher up within that area. As such, before assuming that the bitch is not pregnant, move the probe forwards towards the rib cage from the initial test area, in the same manner as before to seek an accurate result.
The probe should be held firmly against the bitch's body, but not pressed so as to cause pressure to the abdominal cavity. Directing the ultrasound waves almost vertically may cause the reflection of urine in a full bladder, thus providing a false signal of pregnancy.
For accuracy the tests should be conducted on both sides, when the bitch is standing. The best time to test the bitch is when she has an empty stomach and an empty bladder. A full stomach and/or bladder may cause false pregnancy results, by reflecting the ultrasound waves. It is best to confirm the results by testing on 3 occasions.
It comes complete with plastic carrying & storage case, instruction manual & guarantee.
