Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] exist figure 1 Among them, the uterine contraction detector of the present invention, it is controlled by pressure sensor 2, a plurality of body surface electrodes 3, lead wire 4, analog / digital converter 5, microprocessor 7, interface 8, display screen 9, memory 10, The button 11 is connected, and the power supply 6 supplies power for the whole instrument. Analog / digital converter 5 and microprocessor 7 can be integrated on one chip. The pressure sensor 2 is used to collect the pressure signal of uterine contraction from the abdomen 1 of the puerpera and transmit it to the microprocessor 7 . The body surface electrodes 3 are used to collect uterine myoelectric signals from the abdomen 1 of the puerpera and transmit them to the analog / digital converter 5 . The analog / digital converter 5 performs analog / digital conversion on the collected uterine myoelectric...

Abstract

The invention relates to a premature delivery prediction instrument, belonging to the field f clinical detection. The premature delivery prediction instrument comprises a pressure sensor, a boy surface electrode, an analog/digital converter, a microprocessor, an external component and a power supply; the pressure sensor is arranged on the abdomen of the parturient and used for collecting the pressure signal generated during uterine contraction and transmitting the pressure signal to the microprocessor; the body surface electrode is used for collecting the uterine muscle electrical signal from the surface of the abdomen of the parturient and transmitting the uterine muscle electrical signal to the analog/digital converter; the analog/digital converter is used for converting the collected uterine muscle electrical signal from the analog signal to the digital signal and transmitting the obtained digital signal to the microprocessor; the microprocessor is used for processing and calculating the received uterine muscle electrical digital signal and transmitting the obtained result to the external component; and the power supply is used for supplying power to the whole system. The premature delivery prediction instrument is used for predicting the premature delivery of the parturient non-invasively so as to obtain the count-down time of the delivery of the parturient. The premature delivery prediction instrument can be also used for monitoring the uterine contraction of the parturient.

Description

technical field [0001] The invention belongs to the field of clinical detection and relates to a premature birth predictor. Background technique [0002] There are three main reasons for maternal dystocia during childbirth: abnormal fetus, abnormal birth canal and abnormal labor force. Fetal abnormalities and birth canal abnormalities can be accurately predicted by ultrasound and other means before delivery, and abnormal labor force can only be detected during delivery. Abnormal labor force is mainly manifested as uterine contraction weakness or uterine contraction disorder during childbirth. Therefore, it is very important to detect the strength and coordination of uterine contraction to predict whether the parturient can give birth smoothly. On the other hand, so far, the existing technology cannot accurately predict the delivery time of the parturient, and the prediction of premature delivery is still based on the calculation of risk factors. Although many risk factors ...
