Household fetus-voice meter

Abstract

The invention discloses a household fetus-voice meter. The household fetus-voice meter comprises an outer casing and a memory module, a clock module, a wireless module and a display module which are connected with a main control module, wherein a power source module, the main control module and a probe module are arranged in outer casing; an oscillator, a pulse generator, an analog to digital converter and a signal detection module are arranged in the outer casing; the probe module is used for receiving a reflected ultrasonic signal, and returning the reflected ultrasonic signal back to the analog to digital converter to convert into a digital signal; the signal detection module is respectively connected with the probe module and the main control module, and is used for detecting the intensity of the ultrasonic signal received by the probe module, and returning a detection value back to the main control module, and the main control module is used for transmitting to peripheral equipment to display; the probe module is provided with a signal intensity adjusting function. The household fetus-voice meter has the advantages that the fetus-voice can be quickly found and positioned; by adjusting the position of the ultrasonic sensor, the intensity of the fetus-voice monitoring signal is improved, and is stable, and the accurate monitoring result is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fetal heart monitors, in particular to a household fetal heart monitor. Background technique [0002] Fetal heart monitor is an instrument used to monitor fetal heart rate, usually divided into two types: medical and household. By monitoring the fetal heart rate, we can understand the reaction of the fetal heart rate during fetal movement and uterine contraction, so as to speculate whether the fetus is hypoxic in the uterus. The normal fetal heart rate is 110-160 beats / min. Times / minutes all indicate fetal intrauterine hypoxia and should be treated in time. [0003] Household fetal heart rate monitors use the principle of ultrasonic detection to monitor fetal heart rate. For example, a fetal heart rate monitor disclosed in patent announcement number CN203914959U includes an ultrasonic probe, a data analysis component and an intelligent terminal. For the returned ultrasonic chip, first point the ultrason...

Problems solved by technology

[0004] The common problems of existing household fetal heart rate monitors are: it is difficult to find and locate the fetal heart rate, and the fetal heart rate signal strength is unstable during the monitoring process, resulting in inaccurate monitoring results; in addition, most of the existing fetal heart rate monitors use a handle structure, Not good for pregnant women to use alone
