Abstract
The utility model discloses a gynecological medical examination product and particularly discloses a fetal sound sensor which comprises a cavity and is characterized in that a metal plate is arranged on the bottom layer in the cavity; a piezoelectric transducer is arranged on the metal plate; the piezoelectric transducer is connected with a signal amplifier through an insulating layer; and the signal amplifier is connected with an outer stethoscope through a lead. The fetal sound sensor has the beneficial effects that the result is accurate and reliable, the operation is simple, mother and child are not injured, the cost is low, and the fetal sound sensor is suitable for batch production.
Description
Technical field
This utility model relates to a kind of gynecological medical examination articles for use, relates in particular to a kind of tire sound sensor.
Background technology
The anemia of pregnant woman makes regular check on after conceived, and the conventional prenatal diagnosis of hospital now comprises measurement fetal rhythm, the fetus position, takes blood pressure, weighs, surveys abdominal circumference and height of fundus or the like.Wherein monitoring fetal heart frequency is a technical very strong job, because fetal heart frequency is very fast, per minute is between 120-160 time, and with traditional stethoscope, artificial counting is difficult to measure accurately.So general supersonic Doppler instrument that adopts with enlarging function.Statistics have shown to cost an arm and a leg the supersonic Doppler instrument of function that general hospital seldom uses.Can't popularize at middle and small hospital and vast rural area.Hyperacoustic in addition shock effect is to the production detrimental effect of fetus.Although it is very low to detect dosage, also belong to and diminish the detection category, be not suitable for frequent, repeated inspection, also be not suitable for family and use.
Therefore to those skilled in the art, invent a kind of new tire sound sensing detection equipment, in time obtain fetus information, become those skilled in the art's problem demanding prompt solution by the tire sound.
The utility model content
The utility model proposes a kind of novel tire sound sensor, this tire sound sensor is by signal preamplifier, and amplifying signal makes the tire sound transmit receiver with clear, with low cost, radiationless, effective.
This utility model solves the problems of the technologies described above the technical scheme that adopted as following description:
A kind of tire sound sensor comprises cavity, it is characterized in that: bottom is a sheet metal in the described cavity, and sheet metal is provided with piezoelectric transducer, is connected with signal amplifier by insulating barrier on the piezoelectric transducer, and signal amplifier is connected with outer receiver by lead.
