Abstract

The invention relates to the field of medical equipment detection, in particular to a fetal heart rate detecting system. The fetal heart rate detecting system comprises a fetal heart probe, a signal processing circuit, a converter circuit, a programmable logic device, a data processing module, a serial communication interface and a computer system in sequential connection, wherein one-way transmission is carried out among the fetal heart probe, the signal processing circuit and the converter circuit, and two-way data transmission is carried out among the converter circuit, the programmable logic device, the data processing module, the serial communication interface and the computer system. The fetal heart rate detecting system has the advantages that the multi-path extraction of fetal heart sound signals is realized, the fetal heart rate overturning phenomenon is overcome, and the accuracy, the real-time performance and the practicability of fetal heart rate calculation are improved, so the fetal heart rate can more accurately reflect the fetus condition, and the clinical value of fetal heart rate monitoring is improved.

Description

technical field [0001] The invention relates to the field of medical equipment detection, in particular to a fetal heart rate detection system. Background technique [0002] An important part of perinatal fetal monitoring in the fetal heart rate monitoring room. In the past, the diagnosis of fetal heart rate was only a rough fetal heart rate monitoring index obtained through naked eye recognition, manual measurement and calculation, so as to predict the health status of the fetus. And reserve status, the results obtained in this way are often inaccurate, and the error rate is high, which can no longer meet the needs of modern medicine. Contents of the invention [0003] The invention aims at proposing a fetal heart rate detection system which can accurately reflect the condition of the fetus. [0004] Technical scheme of the present invention is: [0005] A fetal heart rate detection system, including sequentially connected fetal heart probe, signal processing circuit, ...
