Embodiment Construction

[0051] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0052] A fetal heart rate detection sensor matrix of a multi-dimensional channel sensor provided by the present invention includes a plurality of sensors. Each sensor includes multiple sound-sensitive unit groups, such as figure 1 As shown, each sound-sensitive unit group includes a plurality of sound-sensitive units 1 . Such as figure 2 In the shown embodiment, 16 sound-sensitive units 1 are divided into four groups, but the present invention is not limited to this. Multiple sound sensitive unit gr...

Abstract

The invention provides a fetal heart detection sensor matrix of a multidimensional channel sensor, and fetal heart detection equipment. The fetal heart detection sensor matrix of the multidimensionalchannel sensor comprises a plurality of sensors, wherein each sensor comprises a plurality of sound sensitive unit groups; the plurality of sound sensitive unit groups adopt difference measurement toform a single collection channel; and each sound sensitive unit group comprises a plurality of sound sensitive units. By using a passive sensor, the potential hard of active emission to a pregnant woman and a fetus is completely avoided; interference noise is effectively inhibited, so that the activities in daily life cannot influence fetal heart monitoring data; lying still for measurement is notneeded; signals can still be accurately measured under the condition that the fetus position of the fetus moves; and the use by the pregnant woman or family members is convenient.

Description

technical field [0001] The invention relates to the field of medical detection equipment, in particular to a fetal heart detection sensor matrix of a multi-dimensional channel sensor and fetal heart detection equipment. Background technique [0002] The basic principle of the traditional fetal heart rate monitoring method based on ultrasonic transmitters is to transmit signals to the abdomen of pregnant women, and the ultrasonic signals will generate reflections when they pass through different parts of human tissue. When the ultrasonic signal encounters the fetal heart, it will also be reflected, and this reflection will produce a Doppler frequency shift due to the motion characteristics of the target. By observing the speed of frequency offset change, it can be used to analyze fetal heart rate data. [0003] This kind of fetal heart rate monitoring method based on ultrasonic emission is still in use today. The main problems with this approach are: [0004] 1) Actively t...
