Wireless matrix pressure monitoring device and method

Abstract

A wireless uterine pressure monitoring device comprises a pressure sensor, a uterine pressure signal processing circuit, and a wireless communication module which are connected in sequence to form one body, wherein the pressure sensor converts abdominal uterine pressure signals of pregnant women into electrical signals, the electrical signals are exported to the uterine pressure signal processing circuit for undergoing amplifying-filtering processing, and then the electrical signals are imported to the wireless communication module which transmits the uterine pressure electrical signals to a wireless receiving device of a fetus monitoring host machine. The invention employs a structure in which the wireless communication technology, the pressure sensor, and the uterine pressure signal processing circuit are combined into one piece, and a uterine pressure signal collecting device is separated from the monitoring host machine, thereby effectively ensuring that the pregnant women are not restricted by the monitoring host machine and can move about freely and conveniently, and fully guaranteeing the reliability and accuracy of each monitoring parameter.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device and method for monitoring uterine pressure in pregnant women. Background technique [0002] Fetal surveillance is a method to evaluate the development and safety status of the fetus in utero by means of biophysics and biochemistry. Fetal monitoring is an important means to ensure the safety of mothers and fetuses and to achieve prenatal and postnatal care. Traditional fetal monitoring refers to electronic fetal heart rate monitoring (Electronic FetalHeartRate Monitoring, EFM) and fetal heart contraction monitoring (cardiotocography, CTG). With the society's increasing requirements for the health and safety of mothers and infants, the study of the physiology and pathology of fetal development has become an important topic. In particular, fetal heart contraction has a wide range of clinical application prospects and in-depth research significance. [0003] Pregnant women ...

AI Technical Summary

Problems solved by technology

Especially during the delivery process, the movement and body position changes of the parturient will pull the lead wire of the monitoring device, resulting in poor contact between the pressure sensor and the parturient or a position deviation, resulting in errors in monitoring parameters

Simultaneously, all kinds of wires are entangled on the body of the puerpera, which brings great inconvenience and discomfort, and even affects the physiological and psychological conditions of the puerpera in severe cases.

These disadvantages are especially evident during long-term monitoring and water birth
