Description

Ultrasonic doppler diagnostic apparatus for livestock pregnancy

Domestic animal gestation ultrasonic doppler diagnostic apparatus is to carry out the instrument that pregnancy check is diagnosed with ultrasonic Doppler technique by the domestic animal rectum, belongs to medical instruments field.

Present ultrasonic Doppler technique is used quite universal aspect the obstetrics and gynecology hospital pregnancy check, and technology is also ripe.But using the field poultry, then is a novel detection technique.According to the domestic animal characteristics, we at first develop SCD-2 type supersonic doppler detector at home, use instrument though SCD-2 type supersonic doppler detector is advanced poultry, and it still has shortcoming.

What 1, it adopted is main frame, the probe separation structure, and in surveying the domestic animal process, user promptly will insert probe in the domestic animal rectum and carry out high position detection, controls domestic animal again and adjusts host switch, volume etc.Therefore hands of user will be taken probe detection like this, and the another hands will be controlled domestic animal, often attends to one thing and lose sight of another, uses very inconvenient, and work efficiency reduction.When domestic animal is not tamed, easily cause the line between main frame and the probe to break damage again in addition.

Though what 2 probe segments adopted is ellipse garden type structure, this structure still is unfavorable for the turnover of domestic animal anus.

3, the probe connecting rod adopts the structure of articulated joint, and feeler is assembled into one or when taking apart, inner lead all will twist rotation to some extent, therefore often come in contact bad or broken string in each use like this, and influence is used.

4, owing to the SCD-2 type be with probe detection to Doppler signal sound be subjected to the influence of surrounding to cause the audition difficulty with being easy to like this of pronouncing of the little speaker on the main frame.

The purpose of the present utility model is to overcome the defective of prior art and invents a kind of big domestic animal ultrasonic doppler rectum gestation diagnostic apparatus.This diagnostic apparatus adopts main frame, the feeler integral structure, with probe, circuit, and power pack all concentrate among the feeler, very easy to use.

This utility model is realized by following technical scheme; With metal or plastic hollow bar (being metal or plastic tube) is the feeler skeleton, be divided into two sections before and after the feeler, two sections join with the spiral shell button, the top of leading portion connects a lucite or plastics probe, probe is ellipse garden annular solid, in one side of ellipse garden annular solid probe middle part, adorn ultrasonic transducer one piezoelectric chip, two wiring boards are installed in the leading portion feeler, in the leading portion feeler top and the probe junction mouth of pipe, a socket is installed, piece wiring board before hub tail connects with lead, the socket front portion connects the ultrasonic transducer that is positioned on the probe middle part with lead, before and after wiring board also connect by lead, be connected with socket in being installed in the leading portion feeler tail end mouth of pipe with lead equally at back piece wiring board tail end.In the one section feeler in back battery supply is housed, number batteries polyphone is contained in the lucite sleeve pipe, is contained in then in the back segment feeler.Respectively there is a bit of female thread at the telescopic two ends of lucite, the front end screw thread connects a bit of copper pipe, the rear end a bit of lucite tube that is spirally connected, all there is an aperture pass-out to connect dipolar lead on two sections tubules, the front end copper pipe connect a High-frequency plug just in time with supporting the plugging together of socket of leading portion feeler tail end, connect a socket at the tail end tube head, this socket exposes just in time and supporting the plugging together of plug that is connected lead one end by handle afterbody delivery outlet, and the lead other end also has plug to connect earphone or sound reproducer.

Its operation principle is; As long as will be positioned on two sections plugs and sockets on the feeler plugs together, two sections feeler interfaces are tightened, again the socket of handle afterbody is plugged together with plug on being connected earphone or playback system lead, the diagnostic system circuit is just connected work automatically, when probe puts in the domestic animal rectum, after processing of circuit, just the sound that can reflect by earphone or sound reproducer is made reliable diagnostic to ultrasonic transducer with the doppler information that detects.

Circuit of the present utility model is achieved in that T ₁The agitator that the LC loop that links to each other with its colelctor electrode is formed sends a high-frequency signal, through B ₁Inductive is transported to by T ₂T ₃The push-pull amplifier of forming is transported to transmitting crystal PQ after amplifying ₁On.This signal is through receiving crystal PQ ₂Receive, pass through B ₂Be coupled to T ₄The High Amplifier Circuit that pipe is formed is behind diode detection, by T ₅And T ₆The amplifying circuit of forming amplifies, again through IC ₁Power amplifier amplifies back output, and outfan is A.Be realization noise reduction purpose, ad hoc meter noise reduction loop, the noise reduction loop is by diode D ₁, transistor T ₇Form, from the power amplifier ic chip ₁5 foot output signals, feed back to T through diode ₇Base stage, treated feedback signal is from T ₇Power amplifier piece IC is delivered in colelctor electrode output again ₁ Input 3 feet are to realize the noise reduction purpose.T ₁T ₂T ₃Adopt 9011, T ₄Use 3DJ8K, T ₅Use 3DJ6E, T ₆T ₇Use 3DG6.IC ₁Adopt LM386, diode D ₁Use 1N4148.

Socket 3 is drawn at the output terminals A place, in plug (22) the insertion socket (3) with the sealed receiver of biphone (25), then can hear DOPPLER ULTRASOUND SIGNAL in earphone.

For the many people consultation of doctors or carry out numeral, then need amplify DOPPLER ULTRASOUND SIGNAL, so design adds sound reproducer (26).The sound reproducer circuit is that the DOPPLER ULTRASOUND SIGNAL from output terminals A is introduced, through IC ₂The most laggard speaker of power amplifier.The DOPPLER ULTRASOUND SIGNAL playback is come out.Sound reproducer input plug (23) inserts in the socket (3), then uses speaker the playback of many DOPPLER ULTRASOUND SIGNAL.IC ₂Use TDA2822M.
