INTRODUCTION
The DRAMINSKI Ultrasonic Pregnancy Detector for Dogs 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 for Dogs 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.
DESCRIPTION
The DRAMINSKI Ultrasonic Pregnancy Detector for Dogs consists of the
following:
1.
The instrument body with red and green signalling diodes, on/off
button, battery compartment, probe connector-cable output
terminal and a variable gain control to ‘set’ for the size & weight
of the bitch to be tested.
2.
Ultrasonic sensor probe with co-axial connecting cable.
3.
Alkaline 9 volt battery inside the battery compartment of the
instrument body.
4.
Plastic carrying and storage case.
TEST SETTINGS
Setting the potentiometer (gain control) correctly, is a very important
factor, which influences the validity of the results obtained by testing.
Bitches vary in regards of weight and size for different breeds and thus
the gain 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:
S
For small bitches
M
For medium size bitches
L
For larger bitches
G
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.
