Embodiment

[0028] refer to figure 1 The present embodiment provides a conformable fetal heart rate monitoring sensor, which is characterized in that it includes a curved shell 101 and an ultrasonic transducer 102, and the radius of curvature of the inner surface of the curved shell 101 ranges from 15 to 40 cm.

[0029] Clinically, fetal heart rate monitoring is generally used for pregnant women after 28 weeks. At this time, due to the increase of the fetus in the body, the abdomen of the pregnant woman is in the shape of a curved spherical surface. In order to make the fetal heart rate monitoring sensor better fit the maternal abdomen, the inner surface of the fetal heart rate monitoring sensor, that is, the surface that fits the maternal abdomen, is designed to have a structure similar to the shape of the maternal abdomen, which is conducive to improving the comfort of maternal monitoring. Of course, there are some differences in the curvature of the abdomen of different pregnant women,...

Abstract

The invention provides a conformal fetal heart monitoring sensor. The conformal fetal heart monitoring sensor is characterized by comprising a curved outer shell and ultrasonic transducers, the radius of curvature of the inner surface of the curved outer shell ranges from 15 cm to 40 cm, and the area of the inner surface of the curved outer shell is not smaller than 35 cm<2>. The invention further provides a work method of the conformal fetal heart monitoring sensor. The work method is characterized by comprising the following steps of dividing the ultrasonic transducers into multiple sets, sequentially operating each ultrasonic transducer set, analyzing the monitored fetal heart sound signal intensity when each ultrasonic transducer set operates, and selecting the ultrasonic transducer set with the strongest monitored fetal heart sound signal to work. By means of the conformal fetal heart monitoring sensor and the work method thereof, the shape of the inner surface is similar to the shape of the abdomen of a puerpera, the sensor better fits the abdomen, and monitoring is more comfortable; the area of the inner surface is larger, the coverage area of an ultrasonic field is large, and the fetal heart monitoring performance is not reduced and the ultrasonic launching dosage is not increased while the monitoring comfort is improved and the coverage area of the ultrasonic field is increased.

Description

technical field [0001] The invention relates to the field of medical monitoring, in particular to a conformal fetal heart rate monitoring sensor and a working method thereof. Background technique [0002] At present, the most widely used electronic fetal heart monitoring method in clinical practice is fetal heart contraction monitoring (Cardiocotography, CTG). When monitoring fetal heart rate and uterine contraction, it is necessary to record the fetal heart rate uterine chart in real time, including the fetal heart rate curve (fetal heart rate, FHR) and the uterine contraction curve (tocography, TOCO) of the mother's uterine pressure. Then, the doctor analyzes the fetal heart rate and uterine contraction curve according to certain standards, and then evaluates the health status of the fetus. [0003] Among them, the fetal heart rate monitoring is based on the ultrasonic Doppler principle, and the ultrasonic chip is placed close to the abdomen of the pregnant woman to monit...
