Low-power-consumption portable wearable fetal heart rate monitoring equipment and fetal heart rate monitoring system

Abstract

The invention provides low-power-consumption portable wearable fetal heart rate monitoring equipment and a fetal heart rate monitoring system.The low-power-consumption portable wearable fetal heart rate monitoring equipment comprises a flexible fetal heart rate sensor and a host, and the flexible fetal heart rate sensor is detachably connected with the host. And the flexible fetal heart sensor and the host jointly form a sound amplification chamber. The flexible fetal heart sensor and the host jointly form a sound amplification cavity, fetal heart sound can be effectively extracted and amplified, and a clear fetal heart rate curve is obtained. In principle, the device uses an auscultation principle, belongs to passive acquisition of fetal heart rate signals, is safer than an ultrasonic principle, and can be used for a long time. In addition, the low-power-consumption portable wearable fetal heart rate monitoring equipment is small in size, can provide long-time data acquisition, can monitor the motion state of a parent body, and can report accidents to a remote cloud service platform in time.

Description

technical field [0001] The invention relates to fetal heart rate monitoring technology, in particular to a low power consumption portable and wearable fetal heart rate monitoring device and a fetal heart rate monitoring system. Background technique [0002] With the development of science and technology, the fetal monitoring system is more and more widely used in ensuring perinatal safety and reducing pregnancy risks. Among them, fetal heart rate monitoring is an important inspection in the third trimester of pregnancy, which can relatively objectively and clearly reflect the safety of the fetus in utero. Fetal heart rate monitoring is the main detection method to correctly evaluate the status of the fetus in the uterus, and plays an important role in early detection of abnormal fetal heart rate and timely treatment to reduce perinatal mortality. Fetal heart rate monitoring The fetal heart rate is regulated by the sympathetic and parasympathetic nerves. By tracing the curve...

AI Technical Summary

Problems solved by technology

[0004] There are many disadvantages in the traditional fetal heart rate monitoring method: (1) In the traditional fetal monitoring system, pregnant women regularly go to the hospital for monitoring, which takes a long time and requires a relatively large number of medical resources, and its paper-based monitoring data is not conducive to archiving and clinical research analysis

(2) The traditional fetal heart monitoring methods mostly use monitoring equipment based on the principle of ultrasound Doppler. The limited information of fetal heart activity that can be obtained by such equipment itself is not conducive to comprehensive analysis by medical staff. Secondly, ultrasound Doppler fetal heart monitor It emits a beam of ultrasound to the fetus, and uses the principle of ultrasound reflection to measure the fetal heart rate.

The effects of thermal effects and cavitation on the ultrasonic waves are currently unknown

(3) The traditional fetal heart rate monitoring equipment is too bulky to be worn by pregnant women, and the battery life is too short to provide all-weather monitoring for high-risk pregnant women.

(4) The existing portable fetal heart monitoring equipment is mostly a single monitoring equipment lacking remote platform support, and cannot connect with the hospital in real time to play a role in timely consultation when problems arise
