Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0034] Such as figure 1 As shown, the portable uterine contraction pressure monitoring system based on NFC and Bluetooth mainly includes the signal acquisition terminal of the lower computer and the signal receiving and display terminal of the upper computer. The former is responsible for performing AD conversion on the collected pressure signal, and then sending it to the host computer via Bluetooth. The upper computer processes the received signal accordingly, and then realizes functions such as display and storage.

[0035] Such as figure 2 As shown, the system hardware structure diagram mainly includes: power supply circuit, sensor circuit, preamplification and filter circuit, microcontroller peripheral circuit and wireless transmission circuit. The power supply circuit provides voltage for the sensor circuit, the pre-amplification filter...

Abstract

The invention relates to a portable uterine contraction pressure monitoring system based the NFC and the bluetooth. The portable uterine contraction pressure monitoring system comprises a uterine contraction pressure signal acquisition and wireless transmission hardware module and an Android mobile phone upper computer application. A uterine contraction pressure signal output by a sensor is transmitted to a microcomputer after being amplified and filtered to perform AD acquisition conversion, and undistorted acquisition of the uterine contraction pressure signal of a pregnant woman can be achieved. The processed uterine contraction pressure signal is transmitted to an Android mobile phone by means of the NFC and the bluetooth, the relevant application developed in the Android mobile phone performs corresponding computing and processing on the received signal, and functions of signal display, storage and remote transmission can be achieved. By means of the portable uterine contraction pressure monitoring system based the NFC and the bluetooth, acquisition, transmission and storage of the uterine contraction pressure signal are achieved, and the traditional signal acquisition and transmission processes can be simplified.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a portable uterine contraction pressure monitoring system based on NFC and Bluetooth. Background technique [0002] Uterine contractions and fetal heart rate are two very important indicators of prenatal care clinically. Compared with abnormal fetal heart rate, abnormal uterine contractions can play an early warning role in premature labor and miscarriage for pregnant women. However, since the vast majority of pregnant women are first-borns and lack relevant experience, their experience and ability to judge uterine contractions are relatively weak. Clinically, many pregnant women are aware of the risk of premature delivery or miscarriage only when they experience severe abdominal pain, vaginal bleeding, and fluid (broken water). It is often too late to go to the hospital for an examination at this time, resulting in abnormal fetal heart rate or fetal death. [0003] With t...
