Abstract

Disclosed is a digital monitor for fetal heart rate of a remote monitoring net, which is composed of a probe and a main frame of the monitor, the inner portion of which is equipped with a wiring board (2). The wiring board is equipped with transformation circuits AD (2-1) and IC (C5402DSP) (2-2), a liquid crystal display circuit (2-3) and a storage circuit Fiash (2-4), a Doppler probe (8)is mounted on a Doppler probe box (7), a wiring board (9) is arranged inside the box, a supersonic and energy-converting emitter circuit (9-1), a supersonic energy converter (9-2), a receiving and amplifying demodulation circuit (9-3), two-stage amplifying circuit (9-4) are arranged on which. The main frame is provided with a liquid crystal display screen (3), the side surface of the main frame is provided with a volume regulation switch (4), an acoustic frequency output interface (5) and an input interface USB (6), and an acoustic frequency output interface is installed on the Doppler probe box. The utility model resolves the disadvantages that an existing fetus-voice meter can only provide fetal heart voice, but can not count or do remote monitoring. The utility model has the advantages of capability of conveniently providing the curved line of the fetal heart rate and the average heart rate, lightness and portable property, simple structure, easy operation and the like.

Description

Long distance monitoring net digitized fetal rhythm rate monitor

Technical field

This utility model belongs to medical apparatus, particularly a kind of instrument that relates to long distance monitoring net digitized monitoring fetal rhythm rate.

Background technology

The ultrasonic general important tool that fetus-voice meter is detection of anemia of pregnant woman's fetal rhythm rate and fetal monitoring of reining in of joining more, extensive use clinically at present, it is directly to amplify treated fetal heartbeat sound by loudspeaker.This class fetus-voice meter weak point only can provide fetal heart sound, can not count, and user needs to be equipped with in addition clock count; Perhaps digital electronic clock is provided on the instrument, user oneself is determined the time span of timing.Listen the fetal heart sound counting on one side, Yi Bian see clock, because medical worker's traditional habit when detecting fetal heart frequency is selected 10 or 15 seconds time span for use, the heart beating number of times of counting fetus is the numerical value of 1 fen clock time again with its conversion.Like this can be because the inexactness of segment boundary is brought the inaccuracy of overall detection data.Another kind of detecting instrument is on the basis of fetus-voice meter, adopts digital display technology to show fetal rhythm rate data, does not tackle the problem at its root into " seeing " though become " listening ".

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of counting automatically, intuitive display, easy to operate, volume is little, energy is remote-operated, remote digital fetal rhythm rate monitor.

Technical solution of the present utility model: this utility model is made up of probe, monitor main frame, it is characterized in that: probe is made up of ultrasonic transduction radiating circuit, ultrasonic transducer, reception amplification demodulator circuit, two-stage amplifying circuit, audio output interface.The monitor main frame is made up of A/D convertor circuit, IC (C5402DSP), liquid crystal display circuit, Flash circuit.Use the high-speed dedicated digital signal processor to finish the realization that the fetal heart frequency monitor improves auto-correlation algorithm, link to each other with the long distance monitoring main control end by serial ports, with on-the-spot test to fetal heart rate signal by telephone wire, Internet or be wirelessly transmitted to Surveillance center of hospital, realize the fetus long distance monitoring.

The beneficial effects of the utility model are, can provide fetal rhythm rate curve and average heart rate easily in the instantaneous fetal heart frequency of test, and monitor is small and exquisite convenient, and is simple in structure.

Below in conjunction with accompanying drawing this utility model is further elaborated.
