Embodiment 1

[0031] Such as figure 1As shown, an intelligent ultrasonic sensor for fetal heart monitoring includes an MCU main control unit, an ultrasonic processing unit, a grouping drive unit, a chipset unit and a display unit, wherein the chipset unit includes several chipsets and is used for fixed installation The fixed plate of the above-mentioned chip group, several chip groups are distributed on each position of the fixed plate. The chip group can be a piezoelectric ceramic chip group, and of course it can also be other chip groups capable of emitting and receiving ultrasonic waves.

[0032] The MCU main control unit is used to sequentially stimulate the chip groups at each position to emit ultrasonic waves through the grouping drive unit, until the chip group at a certain position receives the reflected ultrasonic waves, and obtains the corresponding demodulation and filtering signals through the ultrasonic processing unit. The demodulated and filtered signal is used to control th...

Embodiment 2

[0054]The difference between this embodiment and Embodiment 1 is that the display unit can also be a display, wherein the display can indicate the position by text or lighted position prompts. The display indicates the position through text. Specifically, when the display displays the texts of upper left, lower left, upper right or lower right, move the intelligent ultrasonic sensor in the corresponding position until the display shows the middle position; when the display shows the middle Orientation, then there is no need to move the intelligent ultrasonic sensor, at this time the intelligent ultrasonic sensor is used to collect fetal heart rate data. Similarly, when the display shows the lighted position, the display can indicate the upper left position, the lower left position, the upper right position or the lower right position through the lighted positions at the four corners, and the lighted position in the middle indicates the middle position.

Abstract

The invention relates to an intelligent ultrasonic sensor for fetal heart monitoring. The intelligent ultrasonic sensor comprises an MCU (microprogrammed control unit) master control unit, an ultrasonic processing unit, a group drive unit, a chipset unit and a display unit, wherein the chipset unit comprises a plurality of chipsets and a fixing plate used for fixing and mounting the chipsets, and the chipsets are distributed in various positions of the fixing plate; the MCU master control unit is used for sequentially exciting the chipsets in various positions to transmit ultrasonic waves through the group drive unit until the ultrasonic processing unit acquires a corresponding demodulation filter signal when a chipset in a certain position receives the reflected ultrasonic waves, and the display unit is controlled according to the demodulation filter signal, so that the display unit displays a position indication corresponding to the position of the chipset in a certain position. The invention further discloses a monitoring method of the intelligent ultrasonic sensor for fetal heart monitoring. The power consumption of the product is low, and the position of the heart of a fetus can be positioned accurately.

Description

technical field [0001] The invention relates to the field of fetal heart monitoring, in particular to an intelligent ultrasonic sensor for fetal heart monitoring and a monitoring method thereof. Background technique [0002] Ultrasonic sensors (probes) are sensors developed using the characteristics of ultrasonic waves. Ultrasound is a mechanical wave with a vibration frequency higher than that of sound waves, which is generated by the vibration of the transducer chip under the excitation of voltage. It has high frequency, short wavelength, small diffraction phenomenon, especially good directionality, and can be oriented as rays dissemination characteristics. [0003] Ultrasonic sensors can not only emit ultrasonic waves, but also receive ultrasonic waves. It has been widely used in fetal monitors. It calculates the instantaneous heart rate of the fetus through the ultrasonic Doppler effect and provides medical evaluation to clinicians. At present, all similar instruments a...
