Problems solved by technology

Due to the consideration of radiation dose, the average monitoring time is usually less than 30 minutes, and the fetal heart signal cannot be monitored for a long time
[0005] Passive fetal heart monitor, this kind of equipment uses the probe to record in the audio frequency range to obtain the fetal heart signal, but this technology is not easy to determine the position of the fetal heart, resulting in the acquired fetal heart signal contains a large number of digestive system noise signals and maternal heart sounds and Breath sounds and noise signals, etc., the signal-to-noise ratio is low, and the quality of the obtained fetal heart signal is poor

Abstract

The invention discloses a fetal heart monitoring apparatus and a fetal hear monitoring method. According to one embodiment, the fetal heart monitoring method includes: setting one of more than three monitoring probes as a transmitting probe and the others as receiving probes; using the transmitting probe to transmit ultrasonic wave; converting each ultrasonic wave received by the receiving probes into audio reflection digital signals; selecting one with highest signal-to-noise ratio from more than two audio reflection digital signals; using the receiving probe which receives the audio reflection digital signal with the highest signal-to-noise ratio, as an optimal monitoring channel, and using the optimal monitoring channel to receive fetal heart acoustic wave, and acquiring fetal heart rate based on fetal heart digital signals converted from the fetal hear acoustic wave. The fetal heart monitoring method according to the embodiment has the advantages that less radiation is caused to the human body during the fetal heart monitoring process, fetal heart measurement accuracy is guaranteed, and long-term fetal heart monitoring is achieved.

Description

technical field [0001] The present application relates to the field of monitoring, in particular to the field of fetal heart rate monitoring, and in particular to a fetal heart rate monitor, a wearable fetal monitoring belt, a method for locating an optimal monitoring channel, and a fetal heart rate monitoring method. Background technique [0002] During pregnancy, if the fetus is in distress in the uterus, it may easily lead to dysplasia or even fetal asphyxia, so it is necessary to monitor the fetal heart rate to prevent the above situation from happening. [0003] There are two main types of fetal heart rate monitors: [0004] Doppler ultrasound fetal heart rate detector, most of the medical fetal heart rate monitoring now uses ultrasound to monitor the fetal heart rate through the Doppler effect. Due to radiation dose considerations, the average monitoring time is usually less than 30 minutes each time, and the fetal heart signal cannot be monitored for a long time. ...
