摘要： An anatomy testing device for determining pregnancy in gilts and sows is disclosed comprising a housing containing an electronic circuit to generate and analyze ultrasonic waves. Located on the exterior of the housing are a transducer probe for emitting ultrasonic waves when in contact with the animal's body, a first light to indicate that proper airless contact has been made between the animal's body and the probe, a second light to indicate pregnancy of the animal because of the increase in fluid content of the uterus, an audible alarm to also indicate pregnancy, a charger plug for recharging the batteries, and a test button to activate the electronic circuit. The circuit comprises an ultrasonic transceiver monolithic integrated circuit, an inverter means, a binary counter means, two AND gate means and R.S. flipflop means to generate, transmit, receive the echo of, analyze, and interpret ultrasonic waves to determine animal pregnancy. The portable anatomy testing device contains a rechargeable battery power supply within the housing to power the electronic circuit, indicator lights and audio indicator.
