INTRODUCTION
The DRAMINSKI U trasonic Pregnancy Detector for Dogs determines
pregnancy in dogs by ocating amniotic f uid in the uterus.
The u trasonic probe (sensor) he d against the skin of the bitch, emits
u trasonic sound waves which are ref ected by the amniotic f uid in the
uterus of the pregnant bitch and return to the probe. The ref ected
sound is then measured and ana ysed by the instrument.
When an air ess contact is made between the head of the probe and the
skin, the instrument signa s this with the diode ( ight) pu sing and a
high-frequency acoustic (sound) signa ing regu ar y once a second.
When pregnancy is detected however, the instrument signa s this with a
rapid pu sing of the diode ( ight) and a corresponding rapid high-
frequency acoustic (sound) signa .
The DRAMINSKI U trasonic Pregnancy Detector for Dogs is idea y suited
to pregnancy determination for individua breeders, arge breeding &
show kenne s, veterinary surgeries and commercia organisations a ike.
It is designed to be easy to use, maintain and provide rapid resu ts with
maximum accuracy.
Testing can be performed from 3 weeks after mating. However the
optima time for accurate diagnosis is between days 25 & 28, because of
the en argement of the uterus at this time and its movement s ight y
downward, c oser to the peritoneum. Testing prior to day 25 is possib e, 3
but accuracy decreases due to insufficient amniotic f uid being present to
ref ect the u trasonic waves. Testing after the optima period is a so
possib e.
DESCRIPTION
The DRAMINSKI U trasonic Pregnancy Detector for Dogs consists of the
fo owing:
1. The instrument body with red and green signa ing diodes, on/off
button, battery compartment, probe connector-cab e output
termina and a variab e gain contro to ‘set’ for the size & weight
of the bitch to be tested.
2. U trasonic sensor probe with co-axia connecting cab e.
3. A ka ine 9 vo t battery inside the battery compartment of the
instrument body.
4. P astic carrying and storage case.
TEST SETTINGS
Setting the potentiometer (gain contro ) correct y, is a very important
factor, which inf uences the va idity of the resu ts obtained by testing.
Bitches vary in regards of weight and size for different breeds and thus
the gain must be set to the particu ar position re evant to the size of the
bitch that is being tested.
For ease the potentiometer has been calibrated to show:
S For sma bitches
M For medium size bitches
L For arger bitches
G For the giant bitches.
With usage, fami iarity and experience, the gain contro can be adjusted
to suit the particu ar bitch, both in terms of breed type and actua size,
so that an optimum setting is achieved to ascertain accurate resu ts.
