Therefore, the existing ultrasonic fetal heart instrument can only measure the fetal heart rate, and the maternal heart rate needs to be measured by other instruments.

Referring to fig. 1, fig. 1 is a schematic diagram of a frame of an embodiment of a one-piece fetal heart doppler apparatus 10 of the present application. The integrated fetal heart doppler apparatus 10 comprises a processor 11, and a first sensor 12 and a second sensor 13 respectively connected to the processor 11. The first sensor 12 and the second sensor 13 are used for acquiring fetal physiological data and maternal physiological data, respectively. The processor 11 is configured to analyze the collected fetal physiological data and maternal physiological data to obtain a fetal heart rate and a maternal heart rate.

The integrated fetal heart Doppler apparatus 10 acquires fetal physiological data and maternal physiological data by using the first sensor 12 and the second sensor 13 respectively.

The fetal physiological data may be data such as signal parameters characterizing the fetal heart rate. The maternal physiological data may be data such as signal parameters characterizing the maternal heart rate. The fetal physiological data may be ultrasonic echo signals acquired by a piezoceramic wafer, or other data characterizing the fetal heart rate. The maternal physiological data includes, but is not limited to, results of mutual authentication of single or multiple signals, such as pulse wave signals acquired by photoelectric sensors, ultrasonic echo signals acquired by piezoelectric ceramic wafers, electrocardiographic signals acquired by electrocardiographic electrodes, or other data representing maternal heart rate.

The integrated fetal heart Doppler apparatus 10 of the present embodiment includes a first sensor 12 and a second sensor 13, which are apparatuses for fetal heart monitoring using ultrasonic Doppler technology, and can be applied to hospitals, clinics, home users, and the like. Compared with a fetal heart Doppler apparatus only used for fetal heart monitoring, the integrated fetal heart Doppler apparatus 10 disclosed by the application is enveloped with the first sensor 12 and the second sensor 13, and fetal physiological data and maternal physiological data can be acquired by corresponding acquisition of the first sensor 12 and the second sensor 13 respectively, so that the maternal heart rate can be acquired simultaneously by using the same integrated fetal heart Doppler apparatus 10, and further the fetal heart monitoring and maternal heart monitoring can be realized simultaneously. The use of the same integrated fetal heart Doppler apparatus 10 reduces the apparatus cost compared to the use of two apparatuses to separately acquire fetal heart rate and maternal heart rate. In an embodiment, the integrated fetal heart doppler apparatus 10 includes a first sensor 12 and a second sensor 13, so that when fetal physiological data and maternal physiological data are acquired by using the first sensor 12 and the second sensor 13 respectively, fetal physiological data can be acquired by using the first sensor 12 on a first portion of a detection object, and maternal physiological data can be acquired by using the second sensor 13 on a second portion of the detection object. The first part and the second part can be the same or different parts, physiological data can be acquired, and the specific position can be adjusted according to the requirement. For example, in an application embodiment, the first portion and the second portion are different portions, the first portion is the abdomen, and the second portion is the hand, so that fetal physiological data can be acquired by using the first sensor 12 of the integrated fetal heart doppler apparatus 10 to acquire fetal physiological data from the abdomen of the detected subject, and maternal physiological data can be acquired by using the second sensor 13 of the integrated fetal heart doppler apparatus 10 to acquire maternal physiological data from the hand of the detected subject. The first sensor 12 is used for acquiring fetal physiological data, and may be a piezoelectric ceramic wafer; the second sensor 13 is used for collecting maternal physiological data, and the second sensor 13 is a photoelectric sensor or a piezoelectric ceramic wafer or an electrocardio electrode, and can also be at least one of the photoelectric sensor, the piezoelectric ceramic wafer and the electrocardio electrode. The integrated fetal heart Doppler apparatus 10 may be an integrated fetal heart apparatus having the first sensor 12, the second sensor 13 and the host computer including the processor 11 as a single unit. The first sensor 12 and the second sensor 13 of the integrated fetal heart Doppler apparatus 10 can be arranged on the same probe of the integrated fetal heart Doppler apparatus, so that the mother fetal heart rate can be directly obtained by using the same probe, a plurality of probes are not needed, the cost of the apparatus can be reduced, and the structure of the apparatus is simplified. For example, in an application embodiment, the integrated fetal heart doppler apparatus 10 is an integrated fetal heart apparatus, and the probe includes a first sensor 12 and a second sensor 13 disposed at different positions of the probe, where the first sensor 12 is used for acquiring fetal physiological data from the abdomen of the detected subject, and the second sensor 13 is used for acquiring maternal physiological data from the hand of the detected subject. The first sensor 12 and the second sensor 13 are on the same probe, but the first sensor 12 acts on the abdomen of the test subject to acquire fetal physiological data from the abdomen, and the second sensor 13 acts on the hand of the test subject to acquire maternal physiological data from the hand. The detection object is a detection object of the integrated fetal heart doppler apparatus 10, for example, a pregnant woman. In an application scenario, in order to realize fetal heart monitoring, a pregnant woman can hold the probe of the integrated fetal heart Doppler apparatus 10 by himself to be applied to the abdomen, so that fetal physiological data can be acquired from the abdomen, and maternal physiological data can be acquired from the hands, thus the fetal physiological data and the maternal physiological data can be monitored at any time and any place without being limited to special scenarios such as hospitals.

When the second sensor 13 is used to acquire the maternal physiological data of the detection object or the second portion of the detection object, the integrated fetal heart doppler apparatus 10 may be a photoelectric sensor, and the maternal physiological data may be a pulse wave signal. The pulse wave signal is a pulse wave signal representing the heart rate of the mother body, which is received by the photoelectric sensor after the photoelectric sensor emits light with preset wavelength to the second parts such as finger abdomen, palm and the like of the pregnant woman, wherein the second parts have rich blood vessels. The light of the preset wavelength of the photosensor may be infrared light of 905nm wavelength and/or red light of 660nm wavelength. The pulse wave signal can be obtained by the infrared light with the wavelength of 905nm or the red light with the wavelength of 660nm, and the blood oxygen saturation can be obtained by the infrared light with the wavelength of 905nm and the red light with the wavelength of 660nm, so that in order to improve the accuracy of obtaining the maternal physiological data, the second sensor 13 can be a photoelectric sensor, and the maternal physiological data can be the pulse wave signal and the blood oxygen saturation, that is, the photoelectric sensor emits the infrared light with the wavelength of 905nm and the red light with the wavelength of 660nm, so as to obtain the maternal physiological data of the pulse wave signal and the blood oxygen saturation. The maternal physiological data are acquired through the photoelectric sensor, so that the short circuit between the electrocardio electrodes caused by the couplant when the electrocardio electrodes are utilized to acquire the physiological data can not influence the effectiveness of maternal signal acquisition.

When the second sensor 13 is used to acquire the maternal physiological data of the detection object or the second part of the detection object, the integrated fetal heart doppler apparatus 10 may be a piezoelectric ceramic wafer, and the maternal physiological data is an ultrasonic echo signal. The ultrasonic echo signal used as the maternal physiological data is an ultrasonic echo signal which is received by the piezoelectric ceramic wafer and used for representing the maternal heart rate after the piezoelectric ceramic wafer transmits ultrasonic pulses with a first preset frequency to a second part such as the hand of a detected object. The piezoelectric ceramic wafer is used for collecting the physiological data of the parent body, so that the short circuit between the electrocardio electrodes caused by the couplant when the electrocardio electrodes are used for collecting the physiological data can not influence the effectiveness of maternal signal acquisition. Since the fetus is located in the abdomen of the pregnant woman and cannot directly contact with the fetus to collect the physiological data of the fetus, when the first sensor 12 of the integrated fetal heart Doppler apparatus 10 is used for collecting the physiological data of the fetus at the first part of the detection object, the first sensor 12 can be a piezoelectric ceramic wafer by applying the ultrasonic principle, and the physiological data of the fetus is an ultrasonic echo signal. The ultrasonic echo signal used as fetal physiological data is an ultrasonic echo signal which is received by the piezoelectric ceramic wafer and used for representing the fetal heart rate after the piezoelectric ceramic wafer transmits ultrasonic pulses with a second preset frequency to a first part of an object to be detected, such as the abdomen. The piezoelectric ceramic wafer for collecting the maternal physiological data and the fetal physiological data can be the same or different. It will be appreciated that the sensor of the integrated fetal heart doppler apparatus 10 may directly act on the mother but not on the fetus, so that the frequency of the piezoelectric ceramic wafer is relatively high when collecting the physiological data of the mother compared to collecting the physiological data of the fetus, and therefore, in an application scenario, the first sensor 12 and the second sensor 13 of the integrated fetal heart doppler apparatus 10 are both piezoelectric ceramic wafers, wherein one piezoelectric ceramic wafer collects the physiological data of the mother from the hand of the detected subject, the first preset frequency of the piezoelectric ceramic wafer includes but is not limited to 3M, the other piezoelectric ceramic wafer collects the physiological data of the fetus from the abdomen of the detected subject, and the second preset frequency of the piezoelectric ceramic wafer is 2M, 2.5M, and so on. The first preset frequency and the second preset frequency can be set by user according to the requirement, and the frequency is not particularly limited herein.

When the second sensor 13 is used to acquire the maternal physiological data of the detection object or the second part of the detection object, the integrated fetal heart doppler apparatus 10 may be an electrocardiographic electrode, and the maternal physiological data may be an electrocardiographic signal. The electrocardiosignals used as the maternal physiological data can be electrocardiosignals of the second parts such as different fingers, palm, limbs, abdomen and the like of the pregnant woman obtained by electrocardiosignals. The electrocardio electrode can comprise a plurality of electrode slices, and electrocardio signals are obtained through potential differences between different electrode slices acting on different parts. Taking an example that the electrocardio electrode comprises two electrode plates, when the electrocardio electrode acquires electrocardio signals among different fingers, the two electrode plates respectively act on the different fingers; when the electrocardio-electrode acquires electrocardio signals between the finger and the palm, one electrode slice acts on the finger, and the other electrode slice acts on the palm; when the electrocardio-electrode acquires an electrocardio-signal between the limb and the abdomen, one electrode slice acts on the limb such as a finger, a palm and the like, and the other electrode slice acts on the abdomen, at the moment, the action positions of the two electrode slices are far away, so that the potential difference is large, and the electrocardio-signal can more accurately reflect the maternal physiological data. Compared with the method that an electrocardio electrode is added outside an ultrasonic probe, and when the maternal heart rate is acquired by the abdomen of a pregnant woman, as the couplant is needed to be used in the use process of the ultrasonic probe and belongs to conductors, short circuits between different electrodes are easily caused, the use of the electrocardio electrode is influenced, the disposable electrocardio electrode can increase the use cost of the integrated fetal heart Doppler instrument 10, the metal electrode is also easy to corrode and influence the effectiveness of acquiring maternal physiological data, in the embodiment, when the second sensor 13 is the electrocardio electrode, an action object when acquiring the maternal physiological data is the hand of a detection object, the use of the couplant is reduced, and the influence caused by the short circuits between the electrocardio electrodes due to the couplant can be reduced.

Existing ultrasonic fetal heart doppler instruments, such as doppler ultrasonic fetal heart instruments, may acquire physiological data from the abdomen through a sensor from a fetus or a mother, and are limited by ultrasonic principle limitations, and cannot distinguish whether the acquired physiological data is from fetal heart pulse or pulse of maternal abdominal aorta, umbilical blood flow and the like, so that the calculated heart rate value cannot distinguish whether the fetal heart rate or the maternal heart rate. Therefore, the physiological data acquired by the sensor is considered as fetal physiological data by the general ultrasonic fetal heart Doppler instrument, and the calculated heart rate value is directly used as the fetal heart rate. Therefore, the existing ultrasonic fetal heart Doppler instrument can only measure and obtain the fetal heart rate, and the maternal heart rate needs to be measured by other instruments. When the physiological data acquired by the existing ultrasonic fetal heart Doppler instrument comes from a mother, the existing ultrasonic fetal heart Doppler instrument can take the mother physiological data as fetal physiological data, and when the mother physiological data is low, the lower mother physiological data can be taken as fetal physiological data to slow down, so that the panic of pregnant women and medical staff is caused; when the maternal physiological data is higher, the maternal physiological data can be mistakenly regarded as the fetal physiological data, the real fetal physiological data is covered by the maternal physiological data, and the fetal physiological data cannot be perceived when the fetal physiological data is abnormal, so that the conventional ultrasonic fetal heart Doppler instrument is easy to misjudge because the acquired physiological data cannot be distinguished into pulse pulses from fetal heart pulses or maternal abdominal aorta, umbilical blood flow and the like. In this embodiment, only the first sensor 12 and the second sensor 13 of the same integrated fetal heart doppler apparatus 10 are needed, so that fetal physiological data can be acquired, maternal physiological data can be acquired, and a maternal heart rate can be acquired by using the same apparatus. In this embodiment, the integrated fetal heart doppler apparatus 10 is used to simultaneously acquire the fetal physiological data and the maternal physiological data, so that the use is simple, the operation is convenient, and in addition, the same integrated fetal heart doppler apparatus 10 is used to reduce the cost of the apparatus and simplify the structure of the apparatus. Compared with the prior art, the heart rate of the mother is obtained by adding the second sensor 13 in the uterine contraction pressure probe, in the application, two sensors are directly used on the same equipment, and an additional probe is not needed to add the second sensor 13, so that the inconvenience of using a plurality of probes for the pregnant woman is also relieved. Meanwhile, compared with the prior art, the external maternal electrocardio electrode is externally connected to obtain the maternal heart rate outside the uterine contraction pressure probe, and the technical scheme of the application is that the second sensor 13 is added on the integrated fetal heart Doppler instrument 10 and is used for measuring the maternal heart rate. The integrated fetal heart doppler apparatus 10 is an integrated home-type fetal heart doppler apparatus, which is generally used for measuring fetal heart rate, but because of the limitation of doppler principle in the measurement process, signals such as maternal heart pulse or maternal abdominal aorta or umbilical blood flow can be mixed, and in home use, the real fetal heart rate cannot be identified due to experience deficiency of pregnant women and the like, so the application is convenient for users such as pregnant women to check the real fetal heart rate by arranging the second sensor 13 on the integrated fetal heart doppler apparatus for measuring the physiological parameters of the mother and processing. The user can complete the monitoring of the heart rate of the mother without using the uterine contraction pressure probe and the ultrasonic probe at the same time, and the second sensor 13 is arranged on the same instrument, so that the cost of the instrument can be reduced. Compared with the prior art, the electrocardio electrode needs the use of ultrasonic couplant, can lead to disposable electrocardio electrode to receive the effect that the couplant corrodes, and the second sensor of gathering parent physiological data in this application can be photoelectric sensor or piezoceramics wafer, can not lead to electrocardio inter-electrode short circuit because of couplant etc. influences the validity that mother signal obtained.

The processor 11 of the integrated fetal heart doppler apparatus 10 can analyze the fetal physiological data and the maternal physiological data to obtain a fetal heart rate and a maternal heart rate, respectively. The specific cases are as follows:

maternal-fetal heart rate may include a maternal heart rate that characterizes a maternal pulse rate value and a fetal heart rate that characterizes a fetal pulse rate value. After the first sensor 12 and the second sensor 13 of the integrated fetal heart doppler apparatus 10 are used to acquire fetal physiological data and maternal physiological data, the fetal physiological data can be analyzed to obtain a fetal heart rate, and the maternal physiological data can be analyzed to obtain a maternal heart rate. The method for analyzing the fetal physiological data and the maternal physiological data may be any algorithm capable of realizing the fetal physiological data analysis and the maternal physiological data analysis, and is not particularly limited herein.

When the processor 11 analyzes the maternal physiological data to obtain the maternal heart rate, the maternal heart rate is obtained by analyzing the maternal physiological data according to different ways of collecting the maternal physiological data by the first sensor 12 and the second sensor 13 of the integrated fetal heart Doppler apparatus 10, for example, according to different types of the second sensor 13, by adopting different processing ways. In an embodiment, the second sensor 13 is a photoelectric sensor, and the maternal physiological data is a pulse wave signal, so that when the processor 11 analyzes the maternal physiological data to obtain the maternal heart rate, the processor 11 is further configured to determine an envelope of the pulse wave signal, and obtain the maternal heart rate based on the envelope. If the second sensor 13 is a photoelectric sensor, the maternal physiological data is a pulse wave signal and a blood oxygen saturation level, and the processor 11 is further configured to obtain a maternal heart rate based on the envelope of the pulse wave signal and the blood oxygen saturation level. In another embodiment, the second sensor 13 is a piezoelectric ceramic wafer, and the maternal physiological data is an ultrasonic echo signal, so that when the processor 11 analyzes the maternal physiological data to obtain the maternal heart rate, a maximum frequency envelope signal in the ultrasonic echo signal can be obtained, and the maternal heart rate is obtained based on the maximum frequency envelope signal. In yet another embodiment, the second sensor 13 is an electrocardiograph electrode and the maternal physiological data is an electrocardiograph signal, so that when the processor 11 analyzes the maternal physiological data to obtain the maternal heart rate, the electrocardiograph signal can be analyzed to obtain the maternal heart rate.

When the first sensor 12 is a piezoelectric ceramic wafer and the fetal physiological data is an ultrasonic echo signal, and thus the processor 11 analyzes the maternal physiological data to obtain a maternal heart rate, the processor 11 may be configured to obtain a maximum frequency envelope signal in the ultrasonic echo signal, and obtain the fetal heart rate based on the maximum frequency envelope signal.

The processor 11 is further adapted to perform a preset processing of the fetal heart rate and the maternal heart rate after deriving them. After the integrated fetal heart doppler apparatus 10 acquires the fetal heart rate and the maternal heart rate, the preset processing performed by the processor 11 on the fetal heart rate and the maternal heart rate may be various processing manners such as displaying, processing, analyzing, and the like, which are not specifically limited herein.

In an embodiment, when the processor 11 performs the preset processing on the fetal heart rate and the maternal heart rate, the fetal heart rate may be displayed, for example, the fetal heart rates corresponding to different time points are directly displayed; for another example, fetal heart rate curves are generated using fetal heart rates corresponding to different time points and the fetal heart rate curves are displayed.

In an embodiment, when the processor 11 performs the preset processing on the fetal heart rate and the maternal heart rate, the maternal heart rate may be displayed, for example, the maternal heart rates corresponding to different time points are directly displayed; for another example, a maternal heart rate corresponding to a different time point is used to generate a maternal heart curve and the maternal heart curve is displayed.

In one embodiment, the processor 11 may determine status information regarding the fetal heart rate and/or the maternal heart rate when performing a predetermined process on the fetal heart rate and the maternal heart rate, and display the status information. The status information may be a result of analysis of the fetal heart rate and the maternal heart rate, for example, the status information may include at least one of: quality information of fetal heart rate and quality information of maternal heart rate. The quality information is used to characterize accuracy, reliability, etc. of the heart rate, and the manner of obtaining the quality information is not particularly limited.

Through the above manner, the fetal physiological data and the maternal physiological data are acquired by respectively utilizing the first sensor 12 and the second sensor 13 of the integrated fetal heart Doppler apparatus 10 correspondingly, and the processor 11 respectively analyzes the fetal physiological data and the maternal physiological data to acquire the fetal heart rate and the maternal heart rate, so that the acquisition of the maternal heart rate by utilizing the integrated fetal heart Doppler apparatus 10 is realized. Compare and acquire fetal heart rate and parent heart rate respectively in adopting two instruments, this application scheme adopts with the fetal heart doppler appearance 10 of integral type can reduce instrument cost, and directly utilizes first sensor 12 and second sensor 13 on the fetal heart doppler appearance 10 of integral type to acquire female child heart rate, can simplify the fetal heart doppler appearance 10 integral type fetal heart doppler appearance 10 of instrument structure integral type fetal heart doppler appearance 10.

In order to compare and check the fetal heart rate and the maternal heart rate, the heart rate coincidence of the fetal heart rate and the maternal heart rate is detected, so that alarm prompt is realized, the coincidence interval of the fetal heart rate and the maternal heart rate can be detected, and subsequent alarm processing is carried out. Specifically: first, the integrated fetal heart doppler apparatus 10 acquires fetal physiological data and maternal physiological data by using the first sensor 12 and the second sensor 13, respectively. The processor 11 then analyzes the fetal and maternal physiological data to obtain a fetal heart rate and a maternal heart rate, respectively. Finally, the processor 11 is also configured to detect a coincidence zone of the fetal heart rate and the maternal heart rate, and if a coincidence zone is detected, to issue a prompt and/or to mark the coincidence zone on the displayed heart rate curve.

The overlapping interval of the fetal heart rate and the maternal heart rate may be a part where the detected fetal heart rate and the maternal heart rate are identical or close to each other after the fetal heart rate and the maternal heart rate are checked by comparison. The overlapping interval of fetal heart rate and maternal heart rate indicates that there is a possibility of treating the maternal heart rate as fetal heart rate, or that the heart rate value may be erroneous. When the fetal heart rate and the maternal heart rate are subjected to preset processing, the coincidence interval of the fetal heart rate and the maternal heart rate can be detected, so that the alarm can be realized in a prompting mode and the like under the condition that the coincidence of the fetal heart rate and the maternal heart rate is judged.

In an embodiment, when the processor 11 detects a coincidence interval between the fetal heart rate and the maternal heart rate, a first number of heart rate differences corresponding to different moments in time can be obtained, where the heart rate difference corresponding to each moment is a difference representation value between the fetal heart rate and the maternal heart rate at the moment; counting a second number of heart rate differences meeting the first condition within a first time; if the second number meets the second condition and the heart rate differences in the second time in the first time meet the first condition, determining that the first time is a coincidence interval of the fetal heart rate and the maternal heart rate. The first time and the second time can be set in a self-defined mode, and the second time is smaller than or equal to the first time. The heart rate difference is a difference characterization value between the fetal heart rate and the maternal heart rate, which may be a difference or a standard deviation value between the fetal heart rate and the maternal heart rate, e.g. a sequence of standard deviations between the fetal heart rate and the maternal heart rate is calculated. The first condition may be that the heart rate difference is equal to a preset heart rate difference value; it may be that the heart rate difference is less than a preset threshold, etc., or other conditions that characterize the fetal heart rate and the maternal heart rate as close or coincident. The second condition may be that the second number has a duty cycle in the first number that is greater than the preset duty cycle, that the second number is greater than the preset number value, or the like.

If the processor 11 detects a coincidence zone, it issues a prompt and/or marks the coincidence zone on the displayed heart rate curve. If a coincidence interval of the fetal heart rate and the maternal heart rate is detected, a prompt may be issued. The prompting mode can be any prompting implementation mode, and is not particularly limited herein. For example, the manner of prompting includes at least one of: displaying prompt information, playing prompt sound, turning on a prompt lamp, and the like. The integrated fetal heart Doppler apparatus 10 may include a display screen, a speaker, a prompt lamp, etc. connected to the processor 11, where the display screen may be used to display prompt information, the speaker may be used to play prompt sound, and the prompt lamp may prompt a user through light, so that the processor 11 detects devices such as the display screen, the speaker, the prompt lamp, etc. connected to the processor 11 in the overlapping region, and then alarms in modes such as display screen display, sound, light, etc.

If the processor 11 detects a coincidence zone of the fetal heart rate and the maternal heart rate, the coincidence zone may be marked on the displayed heart rate curve. Wherein the heart rate profile includes at least one of: fetal heart rate generated fetal heart curve and maternal heart rate generated maternal heart curve. The marking method may be any marking implementation, and is not specifically limited herein. In an embodiment, the processor 11 may be configured to generate a fetal heart curve by using fetal heart rates corresponding to different time points, and generate a maternal heart curve by using maternal heart rates corresponding to different time points, and if a coincidence interval of the fetal heart rate and the maternal heart rate is detected, change a color or a line type of a line segment corresponding to the coincidence interval in the heart rate curve, or add a preset mark on the line segment corresponding to the coincidence interval in the heart rate curve. Of course, if the coincidence interval of the fetal heart rate and the maternal heart rate is detected, the alarm can be realized in other ways.

Through the alarm modes such as the prompt and the mark, when the heart rate coincidence condition exists between the fetal heart rate and the maternal heart rate, the alarm can be timely given, so that a user of the integrated fetal heart Doppler instrument 10 is prompted to adjust the position of the integrated fetal heart Doppler instrument 10, confirm the signal source, acquire the fetal physiological data and the maternal physiological data again, analyze and obtain the fetal heart rate and the maternal heart rate, and avoid the maternal heart rate which is mistakenly detected by the integrated fetal heart Doppler instrument 10 as the fetal heart rate, thereby introducing unnecessary clinical intervention.

For the preset processing of the fetal heart rate and the maternal heart rate, the integrated fetal heart doppler apparatus 10 may further comprise at least one functional component comprising at least one of a display screen, a sound playing component and a warning light, connected to the processor 11.
