This is a fully portable, cost effective, ultrasonic instrument which identifies whether or not a bitch is pregnant with maximum accuracy. The detector determines pregnancy by locating amniotic fluid in the uterus.
The Draminski Ultrasonic Pregnancy Detector (DPD) is ideally suited to pregnancy determination for individual breeders, large breeding & show kennels, veterinary surgeries and commercial organizations alike. It is designed to be easy to use, maintain and provide rapid results with maximum accuracy.
The testing procedure consists of simply pressing the ultrasonic probe against the skin. 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.
Diagram 1 - Correct Placement of the DPD Probe
When an airless contact is made between the head of the probe and the skin, the instrument signals this with the light-emitting diode (LED) pulsing and a high-frequency acoustic (sound) signalling regularly once a second.
When pregnancy is detected, the instrument signals this with a rapid pulsing of the LED and a corresponding rapid high-frequency acoustic (sound) signal.
Lifespan of Canine Ova & Sperm and Predicting the Whelping Date:
Bitches ovulate immature ova. It takes between 48 - 72 hours for the ova to ripen after ovulation. The ova remain alive and viable for another 2 - 3 days after ovulation. Fresh or fresh chilled sperm, remain alive in the bitch's reproductive tract for 5 to 6 days. Therefore, successful insemination can occur with the bitch being bred anywhere from 2 days prior to ovulation to 4 days after ovulation.
On the other hand, frozen thawed sperm live only a few hours, therefore it is advised that you work with your Vet and have them perform a transcervical Artificial Insemination (A/I) or a surgical A/I no earlier than 2 - 3 days following ovulation if you are using frozen thawed sperm.
If pregnant, a healthy bitch will whelp exactly 63 days after ovulation, regardless of when she was mated or when her eggs were fertilized. Therefore, knowing the date of ovulation will make your calculations much more precise.
