Description

Wireless Ultrasound Pregnancy Diagnosis by Frequency Modulation

The present invention relates to a wireless ultrasound pregnancy diagnosis by frequency modulation (FM), and more specifically, to reflect the reflected wave returned by the ultrasonic wave in accordance with the blood flow in the blood vessels inside the mammalian organ of the audible frequency A wireless ultrasonic pregnancy diagnosis device that converts to a low frequency band, modulates the converted home frequency, amplifies it, and transmits it to the outside, and diagnoses pregnancy by listening to the home frequency band signal using FM radio (RADIO). It is about.

In general, a pregnancy diagnosis device is widely stocked with various products related to ECG measurement, hormonal treatment method, rectal palpation method, and the like, and the pregnancy diagnosis device is very important for early pregnancy and accuracy.

Convenience and so on.

As a pregnancy diagnosis device, a Doppler type ultrasound pregnancy tester is widely used, and a method of determining whether pregnancy is made by converting an ultrasonic frequency bias according to organ and fetal activity in a living body into an audible frequency and irradiating ultrasound is reflected. Automatic detection equipment that detects the difference in reflection time difference and reflection intensity by returning, and displays the pregnancy status by the letter, and by using the displayed character and ultrasonic detection time difference and the difference in reflection intensity There are imaging equipment for determining pregnancy by 2D image.

However, in the case of using the automatic ultrasonic wave detection system of such a pregnancy diagnostic device, there is a problem that it is difficult for a beginner to diagnose a pregnancy because of the high incidence of misdiagnosis due to the activity of surrounding living organs, and the ultrasonic one-dimensional imaging equipment is digested. Due to defects and expansion of the bladder, the incidence of misdiagnosis is high, skill is required, and the price of equipment is relatively high.

In addition, the ultrasonic two-dimensional imaging equipment has a problem that the operation of the equipment is complicated, and because the skilled technique is required for the ultrasound image reading, pregnancy diagnosis is difficult, and the cost of the equipment is high and at the same time a high cost for maintenance.

Pregnancy diagnosers used to solve the above problems include the use of piezoelectric wave and water wave elements to irradiate the ultrasound in the diagnostic region of the abdomen, and the blood flow of the fetal heart wall or uterine artery by the irradiated ultrasound. As amplification of the ultrasonic waves reflected from the moving surface, which is meticulously and actively, into the audible frequency, that is, sound, the operator listens to the audible band frequency with a headphone equipped with a dedicated receiver to determine whether the livestock is pregnant. will be.

Such a pregnancy diagnosis device is used in a wired or wireless manner, and in the case of a wired line, a worker wears headphones connected to the equipment, adheres a detector to the lower abdomen of the livestock, and detects the blood flow of the fetal heart wall or the uterine artery. Since it is determined whether the livestock is pregnant while wearing headphones to determine whether pregnant, beginners have a problem that it is difficult to determine whether pregnant by the noise around.

In addition, in case of using wirelessly, headphone with a dedicated receiver for transmitting the reflected wave reflected on the fetal heart wall or uterine artery in the audible frequency band and listening to the transmitted frequency is worn. Because it listens in the state, the noise caused by the blood flow and the noise of the livestock (crying) and the specific receiver to listen to the transmission so that it is possible to transmit and receive in a specific frequency band, only the worker wearing the dedicated receiver listens and diagnoses beginners It is difficult to judge whether the livestock is pregnant. In addition, it is more difficult for a beginner to judge whether a livestock is pregnant due to noise in the process of transmitting and receiving through a dedicated receiver, and the working environment of a worker using a dedicated receiver is not good in hot weather. .

Therefore, the present invention was conceived in consideration of the above problems, and its object is to convert the reflected wave returned by the ultrasonic wave into the low frequency band of the audible frequency according to the blood flow in the blood vessel inside the mammalian body, and convert It modulates the home frequency, amplifies and sends it to the outside, and provides a wireless ultrasound pregnancy diagnosis by frequency modulation to diagnose the pregnancy by listening to the home frequency band signal by using the radio signal.

The purpose of the present invention is to use the piezoelectric wave and wave receiving elements to reflect the reflected wave returned by the ultrasonic wave from the living body such as blood flow to the blood vessel of the heart wall of the abdomen or the blood vessel of the uterine artery and the audible frequency band A pregnancy diagnosis apparatus for amplifying a signal and determining whether pregnancy is performed by the amplified signal, comprising: a tuning amplifier detecting an ultrasonic signal reflected from the living body and the electrical signal amplified by the tuning amplifier; A demodulator for converting a blood flow signal of a living body into a low frequency signal of an audible frequency band, a modulator for frequency modulating a low frequency band signal converted by the demodulator to a specific frequency band, and a high frequency of a signal modulated by the modulator Characterized in that consisting of a radio frequency amplifier for amplifying the signal sent out to the outside .
