Description

TECHNICAL FIELD

[0001] The present application belongs to the field of fetal heart monitoring, and in particular to a portable intelligent Doppler fetal heart monitor. BACKGROUND

[0002] Fetal heart monitoring is a crucial examination method during pregnancy. It monitors the fetal heart rate in the mother's body through specific technical means. The frequency and rhythm of the fetal heart can directly reflect the survival status and health of the fetus in the uterus. Under normal circumstances, the fetal heart rate will gradually change with the increase of gestational weeks, and will fluctuate within a certain range. By continuously and accurately monitoring the fetal heart, medical staff and pregnant women can timely detect whether the fetus has abnormal conditions such as hypoxia and distress.

[0003] For example, when the fetus is in the uterus due to reasons such as umbilical cord around the neck and poor placental function, the initial manifestation is often an accelerated fetal heart. If the hypoxia condition cannot be improved in time, the fetal heart will gradually slow down. If these abnormal changes can be detected in time through fetal heart monitoring and appropriate treatment measures are taken, such as timely termination of pregnancy or improvement of the fetus's oxygen environment, the serious consequences of fetal hypoxia, such as brain damage and death, can be greatly reduced, effectively protecting the life safety and healthy development of the fetus. Therefore, fetal heart monitoring is of great importance in protecting the health of mothers and infants and improving the quality of perinatal care.

[0004] For small-scale fetal heart monitoring devices, the current market mainly uses portable fetal heart monitors based on the Doppler principle, which detect fetal heart rate by emitting ultrasonic waves and receiving Doppler frequency shift signals generated by fetal heart movement. After searching, the existing public technologies include:

[0005] 1) The ultrasonic Doppler fetal heart monitor disclosed in CN111544042A includes a main body, a transmission line fixedly connected to the center of the upper end of the main body, a monitor fixedly connected to the end of the transmission line away from the main body, a monitoring head fixedly connected to the end of the monitor away from the transmission line, an automatic smearing mechanism on the monitoring head, and a positioning mechanism installed on the monitoring head. The positioning mechanism is provided to facilitate the user to move the monitoring head to the top of the fetal heart to obtain clear and accurate fetal heart data. At the same time, the eight-direction ultrasonic probe and the center ultrasonic probe together detect the fetal heart, making the obtained fetal heart information more clear and accurate. The automatic smearing mechanism is also provided to make the smearing of the monitoring head more uniform through the liquid outlet pipe and the smearing plate, so as to reduce the amount of coupling agent and avoid waste of the coupling agent. The ultraviolet disinfection lamp is also provided to prevent bacteria on the monitoring head from harming the skin of the pregnant woman and affecting the health of the pregnant woman.

[0006] 2) The disclosure number CN222367716U discloses a high waterproof Doppler fetal heart monitor, in which the patent application comprises: an ultrasonic probe, a host connected with the ultrasonic probe through a connecting line; the host comprises: a shell, a mainboard, a key plate provided with a pressing key, a screen seat, a battery compartment, a loudspeaker, a key cap, a display screen placed on the screen seat, a rechargeable battery arranged in the battery compartment; the shell comprises: a face shell, a bottom shell connected with the face shell, the face shell is provided with a key slot, a loudspeaker hole and a screen slot, the key cap is arranged in the key slot, one end of the key cap is in contact with the pressing key; the display screen extends into the screen slot, and the loudspeaker faces the loudspeaker hole; the joint surface of the face shell is provided with a first waterproof insertion slot, and the joint surface of the bottom shell is provided with a first waterproof insertion ring, the first waterproof insertion ring is matched with the first waterproof insertion slot.

[0007] Among the above-mentioned devices, the fixed size host is usually matched with the separated probe design mode, in order to meet the power supply and signal processing capacity required for normal operation of the device, the host usually needs to be equipped with a larger capacity battery or an external power supply, which makes the host volume larger, and the overall device is similar to the traditional stethoscope or small instrument box. If a pregnant woman wants to monitor the fetal heart, she often needs to go to the hospital or a specific medical place, and cannot monitor the fetal heart in real time at any time and any place in daily life. At the same time, its function is single, can only play fetal heart sound in real time, lacks automatic identification, state early warning and data recording function, needs artificial judgment whether fetal heart frequency is normal, and exists risk of judgment error. In addition, the existing device lacks convenient and effective solution in disinfection, and it is difficult to guarantee the health safety in use process, which easily causes potential threat to the health of pregnant women.

[0033] Working principle:

[0034] Example 1 discloses an integrated portable fetal heart rate monitoring device. It flexibly connects a miniature Doppler ultrasound probe 4 to the main body of a columnar monitor via a rotating positioning ball head 5, eliminating the physical cables between the traditional separate probe and host, forming a compact, integrated terminal. Pregnant women can hold it with one hand or carry it with them. During monitoring, the signal processing and analysis chip incorporates a dedicated Doppler signal DSP and an adaptive noise suppression algorithm. The noise suppression algorithm employs a combination of adaptive Kalman filtering and wavelet transform for noise reduction, combined with dynamic threshold frequency domain bandpass filtering. Through multi-modal algorithms, precise noise reduction is achieved: adaptive Kalman filtering dynamically tracks fetal heart rate signal characteristics and suppresses low-frequency maternal abdominal noise (such as bowel sounds and respiratory interference); wavelet transform performs multi-scale decomposition and reconstruction of the signal to eliminate high-frequency environmental noise (such as electrical noise); and dynamic threshold frequency domain bandpass filtering (20-200Hz effective fetal heart rate band) further extracts pure fetal heart rate Doppler frequency shift signals, significantly improving the ability to capture weak signals and the signal-to-noise ratio, ensuring accurate analysis of fetal heart rate (accuracy ±2 bpm) and rhythm under complex environments. The signal processing and analysis chip captures weak fetal heart signals and suppresses maternal abdominal noise interference, calculating the fetal heart rate in real time (accuracy ±2 bpm) and analyzing rhythm abnormalities. Real-time feedback on fetal hypoxia and other risks is provided via a status indicator light group (red / yellow / green) and a speaker 3 (≥85dB alarm volume). During each monitoring session, the data storage module automatically records the start time, end time, and total fetal heart rate data, forming a complete monitoring log. Users can select historical monitoring records via the display and human-machine interface panel 2, and play back the corresponding fetal heart sounds through the device's speaker 3, facilitating review and analysis of the fetal status by pregnant women and medical staff, and timely detection of abnormal patterns.
