[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a mother-fetus monitor, comprising: An instrument body 1 and a display 2 connected to the instrument body 1 ; the display 2 is generally hinged in a placement slot on the instrument body 1 .

[0023] The wireless probe 9 and / or the wired probe 12 are respectively connected to the instrument body 1 .

[0024] The wired probe interface 8 and the monitoring interface 11 are provided on the instrument body 1 . The wired probe interface 8 is adapted to the wired probe 12 . The monitoring interface 11 is used to connect the pregnant woman monitoring probe. The wired probe interface 8 and the monitoring interface 11 are generally designed to be embedded.

[0025] The probe fixing seat 4 is provided with multiple ones and is installed on the instrument body 1. The probe fixing seat 4 is used to embed the wireless probe 9 and fix the wireless probe 9 through a clamping structure and a clamping structure, and / or, the probe fixing seat 4 is also used to embed the wired probe 12 and fix the wired probe 12 through an arc-shaped support structure and the clamping structure.

[0026] Specifically, the instrument body 1 serves as the main part of the mother-fetus monitor, and a display 2 can be hingedly installed on it. The display 2 serves as a display medium for various data and a human-computer interaction medium. When monitoring the pregnancy of a pregnant woman, a wireless probe 9 and / or a wired probe 12 can be selected according to actual conditions. The wireless probe 9 can maintain a communication connection with the instrument body 1. The instrument body 1 is provided with a wired probe interface 8. Exemplarily, the wired probe 12 is connected to a plug compatible with the wired probe interface 8 through a cable, thereby realizing the connection between the wired probe interface 8 and the wired probe 12, and finally realizing the connection between the wired probe 12 and the instrument body 1. When the pregnant woman monitoring probe is connected to the instrument body 1, the connection can be realized through the same structure. The wireless probe 9 and the wired probe 12 are mainly used to collect fetal heart rate, fetal movement data and other fetal vital signs monitoring data as well as the uterine contraction pressure of the pregnant woman. The pregnant woman monitoring probe is mainly used For collecting maternal vital signs monitoring data such as electrocardiogram, respiration, pulse oxygen saturation, etc., the display 2 can realize the integrated display of the vital signs monitoring data of the mother and the fetus, and there is no need to purchase a fetal monitor or a maternal vital signs monitor separately. For situations where there may be multiple births, such as triplets, you can choose to use wireless probes 9 and / or wired probes 12 (one fetus is adapted to one fetal vital signs monitoring probe) to collect fetal vital signs monitoring data. The number of wireless probes 9 and wired probes 12 can be matched according to the number of fetuses. Those that are adapted to the fetal vital signs monitoring probes are all fixed by the probe fixing seat 4 during storage. The arc-shaped support structure can adopt a notched curved surface fitting structure, the clamping structure can be a hook or a pin, and the clamping structure can be a double-compression-plate type embracing clamping. The clamping structure and the clamping structure realize double fixation, which is more suitable for wireless probes 9 without cable connections.

[0027] When this embodiment is applied in practice, through the setting of wireless probes 9 and / or wired probes 12, the number and type of wireless probes 9 and wired probes 12 can be selected according to actual conditions. The wireless probes 9 and wired probes 12 are mainly used to collect fetal heart rate and fetal movement data and other fetal vital sign monitoring data and pregnant women's uterine contraction pressure. The pregnant women monitoring probe is mainly used to collect pregnant women's electrocardiogram, respiration, pulse oxygen saturation and other pregnant women's vital sign monitoring data, and integrate the pregnant women's and fetuses' vital sign monitoring data on the display 2, so as to realize multi-fetal monitoring including three fetuses, which is helpful for doctors to make fast and accurate clinical diagnosis, and there is no need to purchase fetal monitors or mother's vital sign monitors separately. Further, the probe fixing base 4 can be It is used to fix the wired probe 12 and the wireless probe 9. The cooperation of the arc-shaped supporting structure and the clamping structure can realize the stable fixation of the wired probe 12 by the probe fixing seat 4 under the condition that the two are tightly fitted after the wired probe 12 is embedded in the probe fixing seat 4. The cooperation of the clamping structure and the clamping structure can realize the double fixation of the wireless probe 9 by the probe fixing seat 4 after the wireless probe 9 is embedded in the probe fixing seat 4. Therefore, the wireless probe 9 and the wired probe 12 adopt a universal fixing structure with strong compatibility, which is convenient for the storage, access and management of various probes in clinical practice, avoiding damage that may be caused by placing the probe anywhere after use, and ensuring the stability of the fetal vital sign monitoring probe during the monitoring process and the accuracy of data transmission.

[0028] like Figure 4 and Figure 5 As shown, as an optional embodiment of the present invention, the probe fixing seat 4 includes two arc-shaped pressing parts 41, two arc-shaped fitting parts 42, a U-shaped supporting part 43, a mounting plate 44 and a sealing plate 45, the mounting plate 44 and the sealing plate 45 are arranged relatively to each other along a first direction, and are respectively located on both sides of the U-shaped supporting part 43, the first direction is perpendicular to the plane where the U-shaped supporting part 43 is located, the two arc-shaped fitting parts 42 are respectively arranged at both ends of the U-shaped supporting part 43, one end of each of the arc-shaped pressing parts 41 is connected to one end of the arc-shaped fitting part 42 away from the U-shaped supporting part 43, and the two arc-shaped pressing parts 41 are connected to each other. The tightening portion 41, the two arc-shaped fitting portions 42, the U-shaped supporting portion 43, the mounting plate 44 and the sealing plate 45 enclose a space for embedding the wireless probe 9 or the wired probe 12. The mounting plate 44 is used to be connected to the instrument body 1. The arc-shaped supporting structure includes the arc-shaped fitting portion 42. The clamping structure includes the arc-shaped clamping portion 41. The wired probe 12 is circular. Therefore, when the wired probe 12 is installed, the arc-shaped fitting portion 42 is used to fit with the outer circular surface of the wired probe 12, and the arc-shaped clamping portion 41 is used to clamp the outer circular surface of the wired probe 12.

[0029] Specifically, the first direction is Figure 4 and Figure 5 Along the direction of the X-axis, an embedding space for embedding the wireless probe 9 or the wired probe 12 is formed between the arc-shaped pressing portion 41, the arc-shaped fitting portion 42, the U-shaped supporting portion 43, the mounting plate 44 and the sealing plate 45. This embedding space is similar to a "pocket", and the wired probe 12 or the wireless probe 9 is inserted in this embedding space. The U-shaped supporting portion 43 is located at the bottom, and the outer side of the U-shaped supporting portion 43 can be provided with a multi-layer shell structure, and a plurality of reinforcing ribs staggered horizontally and vertically are provided between the multi-layer shells. The shell can cover the arc-shaped fitting portion 42 and connect to the position of the arc-shaped pressing portion 41, thereby enhancing the overall strength of the probe fixing seat 4, the arc-shaped pressing portion 41, the arc-shaped fitting portion 42 and the U-shaped supporting portion 43 constitute the side of the embedding space and are both fixed to the surface of the mounting plate 44. The sealing plate 45 is arranged parallel to the mounting plate 44, and a notch is provided on the sealing plate 45 to facilitate taking and placing. The wireless probe 9 or the wired probe 12 is partially exposed from the embedding space. When installing the wired probe 12, align the wired probe 12 with the embedding space and insert it downward from the center so that the arc-shaped fitting portion 42 fits with the outer cylindrical surface of the wired probe 12. At this time, the arc-shaped pressing portions 41 on both sides press the outer cylindrical surface of the wired probe 12. The fit ensures stability in the fixed state, thereby achieving the installation of the wired probe 12 on the probe fixing seat 4. The disassembly steps are opposite to the installation steps.

[0030] When this embodiment is applied in practice, whether the wired probe 12 or the wireless probe 9 is installed, it is installed in the embedded space. For the wired probe 12, since it has a cable, the wired probe 12 can be directly fixed on the probe fixing seat 4 through the arc-shaped support structure and the clamping structure, so that the wired probe 12 can be stably stored when not in use.

[0031] like Figure 1 and Figure 2 As shown, as an optional embodiment of the present invention, the mother-fetal monitor meets clinical needs and improves ease of use in terms of structural design. The display 2 is configured as a high-resolution color display screen for clearly displaying the physiological parameters of the fetus and the mother. A printing module 13 is provided under the display 2 to facilitate medical staff to print monitoring reports and records. A probe holder 4 and a wired probe interface 8 are designed on one side of the instrument body 1 to ensure the stability of the probe during the monitoring process and the accuracy of data transmission. A probe holder 4 and a marker holder 7 are provided on the other side for easy management and use. In addition, the display 2 is equipped with a flip handle 14, which is mounted on the instrument body 1 to allow medical staff to easily adjust the angle of the display 2 as needed to obtain the best viewing angle.

[0032] like Figure 1As shown, as an optional embodiment of the present invention, the display 2 is also integrated with a display scanning port 3, which is used to obtain the barcode / QR code information (pregnant woman's bracelet) with the identity mark of the pregnant woman, and transmit the barcode / QR code information to the server of the instrument body 1. The server matches and archives the monitoring data of the fetal monitoring equipment with the existing available pregnant woman information, so that the pregnant woman information can be entered by scanning the code, which greatly shortens the time for information entry, reduces manual operation errors, and ensures the accuracy of the data. The automatically entered information can be immediately synchronized to the central monitoring system (server), which is convenient for unified management and rapid retrieval of data.

[0033] like Figure 5 As shown, as an optional embodiment of the present invention, the wireless probe 9 includes a circular portion 91 and a supporting portion 92 that are fixedly connected. Therefore, when installing the wireless probe 9, the arc-shaped clamping portion 41 is used to clamp the circular portion 91, and the U-shaped supporting portion 43 is used to support the supporting portion 92, and the clamping structure is arranged on the mounting plate 44 and the supporting portion 92.

[0034] Specifically, the circular portion 91 and the supporting portion 92 are fixed to each other, and the shape of the supporting portion 92 matches the shape of the U-shaped supporting portion 43. For example, both are U-shaped. The U-shaped supporting portion 43 can fit with the supporting portion 92 when supporting. Since the arc-shaped clamping portion 41 is located on the relatively outer side of the probe fixing seat 4, the arc-shaped clamping portion 41 on both sides can achieve compression of the periphery of the supporting portion 92. In addition, the clamping structure has a fixing effect. The clamping structure is arranged on the mounting plate 44 and the supporting portion 92, which will not affect the fixation of the wired probe 12. The above can achieve the stable storage of the wireless probe 9 on the probe fixing seat 4.

[0035] like Figure 5 As shown, as an optional embodiment of the present invention, the card connection structure includes a limiting portion 5, a card one 6 and a card two 10, the limiting portion 5 is fixed to the mounting plate 44, the card one 6 is located in the limiting portion 5 and is fixedly connected to the mounting plate 44, a card slot is formed between the limiting portion 5 and the card one 6, the card two 10 is fixed to the supporting portion 92, and the card slot cooperates with the card two 10.

[0036] Specifically, card 2 10 and card 1 6 are both made of elastic material. When installing the wireless probe 9, align the support part 92 with the U-shaped supporting part 43 from top to bottom (negative direction of the Z axis) and insert it with force. When the bottom of the support part 92 and the U-shaped supporting part 43 are in contact, card 2 10 enters the card slot, and the arc-shaped clamping part 41 is in an open state and keeps clamping the circular part 91. The arc-shaped clamping parts 41 on both sides are like a bayonet, clamping the circular part 91 therein, thereby realizing the installation of the wireless probe 9 on the probe fixing seat 4. The disassembly steps are opposite to the installation steps.

[0037] When this embodiment is used in practice, the probe fixing base 4 and the wireless probe 9 are fixed through multi-point contact (the outer circumferential surface of the arc-shaped pressing portion 41 and the circular portion 91, the side surfaces of the U-shaped supporting portion 43 and the supporting portion 92, and the card 2 10 and the card slot). When the wireless probe 9 is not in use, the wireless probe 9 can be stably stored on the probe fixing base 4.

[0038] In summary, whether a wired probe 12 or a wireless probe 9 is installed, it is installed in the embedded space. That is, although the wireless probe 9 and the wired probe 12 have different structures, the wireless probe 9 and / or the wired probe 12 can be stably fixed by designing a universal probe fixing seat 4.

[0039] like Figure 4 and Figure 5 As shown, as an optional embodiment of the present invention, the openings formed by the arc-shaped pressing portions 41 on both sides, the arc-shaped fitting portions 42 on both sides and the U-shaped supporting portion 43 are reduced in sequence.

[0040] Specifically, in Figure 4 and Figure 5 In the figure, viewed along the installation direction (Z-axis direction) of the probe fixing seat 4, the arc-shaped clamping parts 41 on both sides, the arc-shaped fitting parts 42 on both sides and the U-shaped supporting part 43 each form an opening, and the three openings decrease successively, which is specifically reflected in that the distance between the arc-shaped clamping parts 41 on both sides, the distance between the arc-shaped fitting parts 42 on both sides and the opening distance of the U-shaped supporting part 43 decrease successively, so that the distance close to the inner side of the embedded space is smaller than the distance close to the outer side, which is conducive to the firm installation of the wireless probe 9 and the wired probe 12.

[0041] like Figure 3 As shown, as an optional embodiment of the present invention, the probe fixing seat 4 is located on the side of the instrument body 1, and a bolt hole is provided between the mounting plate 44 and the instrument body 1.

[0042] Specifically, bolts are installed in the bolt holes to fix multiple fetal vital sign monitoring probe fixing seats 4 on both sides of the instrument body 1. The probe fixing seats 4 are fixed to the instrument body 1 through the mounting plates 44. One or more fetal vital sign monitoring probe fixing seats 4 can be installed as needed.

[0043] When this embodiment is used in practice, the probe fixing seat 4 and the instrument body 1 can be disassembled and fixed by bolt holes and bolts to enhance the connection stability.

[0044] In summary, see Figure 6 The key function of the mother-fetus monitor is its joint monitoring capability and information management efficiency. The device supports triple or even multiple fetus monitoring. Through the integrated processing of the signals of multiple wireless probes 9 and wired probes 12, it can simultaneously monitor key physiological parameters such as the fetal heart rate, fetal movement and uterine contraction pressure of three or more fetuses. In addition, the device also integrates the mother's vital signs monitoring function (see Figure 6 ), which can display the mother's heart rate, blood pressure, blood oxygen and other data in real time, assist doctors in comprehensive evaluation and monitoring information management (see Figure 6 ), the monitor supports quickly entering the identity information of pregnant women by scanning the barcode or QR code on the pregnant woman’s wristband, and automatically matches and archives the monitoring data through the central monitoring system, greatly improving the efficiency and accuracy of information entry.

[0045] As an optional embodiment of the present invention, the instrument body 1 is used for: Obtaining fetal vital sign monitoring data of all fetuses through the wireless probe 9 and / or the wired probe 12; Obtaining maternal vital signs monitoring data through maternal monitoring probes; Based on the fetal vital sign monitoring data and the pregnant woman's vital sign monitoring data, the status of the fetus and the pregnant woman are determined.

[0046] When this embodiment is applied in practice, for each pregnant woman and her fetus, the fetal vital sign monitoring data of all fetuses can be obtained through the wireless probe 9 and / or the wired probe 12, that is, any one of the three situations can be used to meet the monitoring needs of the number of fetal vital sign monitoring of the fetus, one fetus corresponds to one fetal vital sign monitoring probe, and the pregnant woman's vital sign monitoring data can be obtained at the same time, so that the key physiological parameters of the fetal heart rate, fetal movement and other key physiological parameters of two or even three fetuses can be monitored, and the vital signs of the pregnant woman can be monitored and integrated. In this way, the fetal heart rate of multiple fetuses and the heart rate, blood pressure, blood oxygen and other data of the pregnant woman can be displayed synchronously, reducing the waste of resources, realizing triple fetus monitoring, more accurately evaluating the health status of the fetus, and improving the monitoring safety of multiple pregnancy; further, based on the fetal vital sign monitoring data and the pregnant woman's vital sign monitoring data, the status of the fetus and the pregnant woman can be judged, which helps to assist doctors in rapid assessment and clinical diagnosis of pregnancy status.

[0047] When in use, the wireless probe 9 and the wired probe 12 collect fetal vital signs monitoring data, set the parameters of the mother-fetal monitor, and collect the mother's vital signs monitoring data through the mother's vital signs monitoring probe. The collected fetal vital signs monitoring data, mother's vital signs monitoring data, and the set fetal vital signs monitoring data parameters and mother's vital signs monitoring data parameters are encoded to form encoded data. The display 2 decodes and separates the received encoded data to obtain fetal vital signs monitoring data, mother's vital signs monitoring data, fetal monitor setting parameters and vital signs monitor setting parameters, and displays the separated data.

[0048] As an optional embodiment of the present invention, judging the status of the fetus and the pregnant woman based on the fetal vital sign monitoring data and the pregnant woman vital sign monitoring data includes: Determining whether the fetal vital sign monitoring data and the pregnant woman vital sign monitoring data are both within a corresponding first preset range; If yes, it is determined that both the fetus and the pregnant woman are normal; Otherwise, it is determined that the pregnant woman has an abnormal condition.

[0049] Specifically, the fetal vital signs monitoring data and the maternal vital signs monitoring data include fetal heart rate and fetal movement data respectively. The maternal vital signs monitoring data may also include one or more of the maternal uterine contraction pressure and the maternal electrocardiogram, respiration, pulse oxygen saturation, pulse rate, non-invasive blood pressure, body temperature, etc. Fetal heart rate (FHR): the normal range is approximately between 120-160 times / minute; other indicators (depending on the monitoring equipment): fetal movement (normal activities should be frequent and regular), fetal heart rate variability (good variability usually indicates fetal health), maternal vital signs monitoring data: maternal heart rate: the normal range is approximately between 60-100 times / minute; uterine contraction pressure: normal uterine contraction pressure should be moderate, too high or too low may affect fetal health; maternal electrocardiogram (ECG): no obvious abnormal waveform; respiratory rate: the normal range is 12-20 times / minute; pulse oxygen saturation: should be ≥95%; pulse rate: should be consistent with the heart rate, and under normal circumstances, remain within the above range; non-invasive blood pressure: the normal range is usually 108 / 60 mmHg to 120 / 80mmHg; Body temperature: Normal body temperature should be between 36.5-37.5°C.

[0050] When this embodiment is applied in practice, one or more of the collected fetal heart rate, fetal movement data, uterine contraction pressure, maternal electrocardiogram data, respiration, pulse oxygen saturation, pulse rate, blood pressure and body temperature are compared with their respective corresponding first preset ranges. If the vital sign data of the fetus and the pregnant woman are both within the corresponding first preset range, it can be determined that the health status of the fetus and the pregnant woman is normal, which means that the current pregnancy is in good condition. If any aspect of the monitoring data exceeds the normal range, it may indicate that the pregnant woman has an abnormal condition, so that timely medical evaluation and intervention can be carried out.

[0051] As an optional embodiment of the present invention, the instrument body 1 is also used for: The fetal vital sign monitoring data and the pregnant woman vital sign monitoring data are synchronously displayed on the display 2, and an alarm is issued when it is determined that the pregnant woman has an abnormal condition.

[0052] When this embodiment is applied in practice, it can realize the vital signs monitoring of the mother and the fetus at the same time. The vital signs of the mother and the fetus can be monitored by the same device, which reduces the waste of equipment and resources. When the fetal vital signs monitoring data and the pregnant woman's vital signs monitoring data include the fetal heart rate and the pregnant woman's heart rate respectively, the simultaneous display of the fetal heart rate and the pregnant woman's heart rate helps doctors to make quick and accurate clinical diagnoses, especially in emergency situations.

[0053] As an optional embodiment of the present invention, the number of fetuses is equal to the number of fetal vital sign monitoring probes in use. When a plurality of fetal vital sign monitoring probes are in use, the operating frequencies of the plurality of fetal vital sign monitoring probes are different.

[0054] Specifically, a plurality of fetal vital sign monitoring probes are arranged to be fixed on the abdomen of a pregnant woman (with multiple births) by straps and distributed according to the initial monitoring positions. Different probes have different operating frequencies (the emitted ultrasonic frequencies are different).

[0055] As an extended embodiment of the present invention, the steps of processing fetal vital sign monitoring data include: Acquire the fetal vital sign monitoring data of a plurality of fetal vital sign monitoring probes at an initial monitoring position, wherein the plurality of fetal vital sign monitoring probes include a wireless probe 9 and / or a wired probe 12; Fetal vital sign monitoring data includes fetal heart rate, which can be collected through ultrasound or electrophysiological signals (such as electronic fetal heart rate monitoring, FHR monitoring). Ultrasonic probes, electrocardiogram probes, etc. can be used to monitor the heartbeats of multiple fetuses at the same time.

[0056] Determining whether a difference between the fetal vital sign monitoring data corresponding to two adjacent fetal vital sign monitoring probes is within a second preset range; Specifically, the fetal heart rates of multiple fetuses usually vary due to various factors such as individual differences in the fetuses, health conditions, and fetal positions. In clinical use, the doctor will first determine the position of the strongest fetal heart rate and then select a position for fetal heart monitoring. The physical position of the probe on the pregnant woman's abdomen is different. Generally speaking, two probes will not monitor the same fetal heart rate. If the two probes are placed in the same position, the same fetal heart rate will naturally be monitored. Of course, it cannot be ruled out that the heart rates of the two fetuses may be very close. Generally speaking, the fetal heart rate (fetal heart rate) is in the normal range of 120 to 160 times / minute for wired probes. When the difference between any two fetal heart rates is relatively small, for example, it reaches the set second preset range, such as 20 times / minute, it is considered very likely that the heart rate of the same fetus has been measured, and further judgment is needed.

[0057] If yes, determining whether the fetal vital sign monitoring data corresponding to two adjacent fetal vital sign monitoring probes whose difference is within a second preset range have consistent changes in the same time period; Specifically, when the difference between any two corresponding fetal vital sign monitoring data is within the second preset range, the fetal heart rate over the period of time measured above is further judged over time (obtaining the two groups of fetal vital sign monitoring data), such as whether the peak time points are consistent, and / or whether the fluctuation curves of the fetal heart rate show the same regular changes or the same fluctuations. If so, it is considered that the probes corresponding to the two groups of fetal vital sign monitoring data monitor the fetal heart rates of the same fetus at different positions.

[0058] If they are consistent, it is determined that the two adjacent fetal sign monitoring probes corresponding to the consistent changes in the fetal vital sign monitoring data within the same period monitor the same fetus, and a shift prompt is issued, wherein the shift prompt is used to prompt the monitoring position of at least one of the two adjacent fetal sign monitoring probes corresponding to the monitoring of the same fetus to be moved and the fetal vital sign monitoring data to be reacquired; Specifically, when the probes corresponding to the two groups of fetal vital sign monitoring data monitor the fetal heart rates of the same fetus at different positions, it is necessary to prompt to move the position of at least one of the fetal vital sign monitoring probes, and re-fix it and then monitor until the difference between the re-acquired fetal vital sign monitoring data is no longer within the second preset range. Of course, in a few cases, there may be a low probability that the positions of the two fetuses are close enough and the changes in the same time period are close. At this time, it is necessary to further refine the monitoring, such as improving the recording accuracy and recording frequency of the measurement, and re-comparison. At this time, the second preset range can be modified according to the actual situation.

[0059] If they are inconsistent, it is determined that the changes of the fetal vital sign monitoring data in the same period are inconsistent and the corresponding two adjacent fetal vital sign monitoring probes monitor different fetuses.

[0060] Specifically, in combination with the above situation, if the fetal vital sign monitoring data corresponding to two adjacent fetal vital sign monitoring probes within the second preset range do not change consistently within the same period of time, then they are most likely two fetuses with similar activity levels. At this time, it is considered that the corresponding fetal vital sign monitoring data belong to different fetuses, and the corresponding fetal vital sign monitoring data are valid, and will be used as the basis for subsequent judgment of the status of the fetus and the pregnant woman.

[0061] When this embodiment is applied in practice, it is possible to accurately obtain fetal vital sign monitoring data for multiple fetuses (such as triplets), and accurately distinguish the fetal heart rate of each fetus, thereby realizing multiple fetuses (such as triplets) monitoring, which can more accurately assess the health status of the fetuses and improve the safety of monitoring of multiple pregnancies.
