Description

Continuous ultrasonic wave Doppler searching unit
This utility model relates to a kind of continuous ultrasound ripple doppler transducer, it be medical and animal and veterinary with the core component of pregnant diagnostic apparatus.Be applicable to that early, middle and late phase gestation inspection that obstetrician, mother and child care, family planning and animal and veterinary worker use is examined and the inspection of fetal development, hydatidiform mole, placental localization etc. examine and give a birth fetal heart sound monitoring and the quick inspection of the early, middle and late phase gestation of domestic animal examined.
Existing be used for the supersonic Doppler probe that the gestation inspection is examined,, be single-shot, single probe of receiving as the flat elliptic probe introduced among China patent CN88204392.7 " ULTRASONIC COMPLEX type domestic animal gestation examining instrument " etc.Its weak point is: single-shot, single probe system of receiving adopt cellular-type, the ultrasound wave that half of transducer produces is launched in body, in addition half of transducer receives, by the ultrasonic reflection rule as can be known, angle of incidence equals angle of reflection, when having only measured target to be in rational angle of reflection position, the useful signal of reflected back could be received transducer and receive, can detect.Slightly more partially, angle of reflection is excessive, and useful signal promptly reflects less than on the receiving transducer, thus the inspection examine less than.Single-shot, single receipts probe are subjected to the influence of angle of reflection, and limitation is very big.Owing to measured target (fetus) is in early days very little, and based on the fetal rhythm that detects fetus, the motor message of fetal blood stream, add that lie is very unfixing, particularly domestic animal extremely is difficult for visiting reaching.Obtaining that this kind signal must accomplish to make the emission acoustic beam of probe and receive piezoelectric transducer can be preferably perpendicular to fetal rhythm, form rational angle of incidence and angle of reflection, the fetal movements doppler information of its reflected back just in time is received piezoelectric transducer and obtains just can detecting.Concentric circular is popped one's head in a shade better, diagnoses but also can only just can obtain useful signal in concentric circular probe area scope, accomplishes quite difficulty of this point, reaches extremely difficult in early days spy of gestation especially.Gestation is in early days to family planning with to develop animal husbandry be the most significant.
The purpose of this utility model is to propose a kind of continuous ultrasound ripple doppler transducer.
The purpose of this utility model be achieved in that probe of the present utility model for multiple, overcharge continuous ultrasound ripple doppler transducer, it constitutes a plurality of rectangles or a plurality of concentric circular annular probe by a plurality of piezocrystal transducers, forms the probe of a plurality of emissions and a plurality of receptions simultaneously.
The utility model has the advantages that: multiple owing to adopting, as to overcharge piezocrystal transducer formation continuous ultrasound ripple doppler transducer, it is multiple and overcharge the reception relation that has formed a plurality of emission angle of incidence and angle of reflection, thereby makes extended detection range.Therefore, very easily the Doppler signal that fetus reflects in different angles is examined in inspection.Because the frequency ratio normal person of the fetal rhythm that receives, fetal blood stream Doppler sound or the heart rate of female animal exceed one times (120 times/minute), this is the fetus signal sheerly, accurately and reliably, very easily whether diagnoses gestation.Thereby reach the purpose that the early pregnancy inspection is examined.
