[0002] A fetal heart monitor, also known as a fetal heart rate monitor, can obtain fetal heart movement information from the pregnant woman's abdomen based on the Doppler principle. It is not used for continuous monitoring, but only for obtaining fetal heart movement information. It is mainly an electronic instrument used for fetal heart monitoring. Generally, obstetrics and gynecology hospitals provide fetal heart monitoring to monitor whether the fetal movement is abnormal and take appropriate measures based on the fetal heart condition.

[0003] However, current fetal heart monitors have certain errors in detection results due to the user's movements, body movements, and fetal position, and the ultrasonic transceiver system cannot compensate for the errors caused by the detection process. Therefore, the errors in the detection data of ultrasonic fetal heart monitors are relatively large.

[0027] (III) Beneficial effects

[0028] The ultrasonic transceiver system and fetal heart monitor provided by the present invention have the following beneficial effects:

[0029] 1. Through the ultrasonic transceiver system, the position probe is used to detect the fetal heart position, and then the rotating module is used to drive multiple fetal heart probes to rotate, and the waveforms of each fetal heart probe at the same distance from the fetal heart are compared. When comparing, part of the waveform graph is intercepted, and the peaks of multiple waveform graphs are further aligned and compared, and unreasonable data is eliminated. After integrating multiple groups of valid data, the maximum value, minimum value and intermediate value are taken for user reference, so that multiple fetal heart probes can detect the fetal heart rate at the same time, thereby reducing the error of detection and solving the problem of large error in the detection data of ultrasonic fetal heart monitors in the prior art;

[0030] 2. Through the coordinated use of the transmission component, the self-cleaning smear component and the switching component, the strap driving component drives the transmission component to operate so that the connecting ring moves to the rear end of the rotating component, rotates to make the smear sheet contact with the fetal heart probe, and rotates the smear sheet to the next No. 2 circular hole position and moves forward to the inside of the shell. When the smear sheet is in the No. 2 circular hole, the gel disc contacts the smear sheet to smear gel on the smear sheet, and the wiping disc contacts the smear sheet to wipe off the gel on the smear sheet, thereby achieving the smearing of gel on the fetal heart probe and wiping the gel on the fetal heart probe clean, which solves the problem in the prior art that the gel needs to be manually applied before each use and the probe needs to be cleaned after use;

[0031] 3. Through the coordinated use of the tightness control structure and the strap driving assembly, the fetal heart probe can exert a certain pressure on the pregnant woman's belly, avoiding the enlarged gap between the probe and the skin, and avoiding the data error caused by the relative displacement of the fetus and the probe position caused by the user's own movements and body activities, thus solving the problem of inaccurate detection caused by the user's own movements and body activities in the prior art;

[0032] It can also realize automatic adjustment of the length of the strap drive assembly without adjusting the length of the wearing strap outside the shell;

[0033] 4. Through the coordinated use of the No. 1 pulley, the driven gear, the transmission belt and the active gear ring, the smear sheet rotates while the connecting ring rotates, which is conducive to evenly applying the gel on the fetal heart probe;

[0034] 5. Through the coordinated use of the self-cleaning smearing assembly and the tightness control structure, when the pull rope is pulled, the active gear ring rotates, and the rotation of the active gear ring drives the driven gear to rotate, and then the smearing piece rotates through the smearing piece, the transmission belt and the No. 1 pulley, so that the wiping disc can wipe the smearing piece clean;

[0035] 6. Through the set position probe, the fetal position and the position of its heart can be clearly known, and the fetal heart probe can be accurately aligned with the position of the fetal heart, thereby improving the accuracy of the detection;

[0036] 7. By setting up the lumbar support, pregnant women's waist needs to bear greater pressure when the pregnancy period is long. The waist pressure of pregnant women is reduced when using it, making the device suitable for long-term wearing. When not in use, it can be left on to assist pregnant women in waist support, and the breathable net is breathable. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] Embodiment 4:

[0077] The schemes in Example 1, Example 2 and Example 3 are further introduced below in combination with specific working methods, as described below for details:

[0078] Specifically, when the fetal heart rate monitor is working / in use: the smear sheet 63 contacts the gel disc 74, and the wearing strap 84 is pulled out from the shell 1. During the pulling-out process, the rack 82 moves to drive the transmission outer gear ring 41 to rotate. When the transmission outer gear ring 41 rotates, the sliding disc 45 moves backward through the arc-shaped push block 42, and the driven outer gear ring 44 is driven to rotate through the transmission column 43. The rotation of the driven outer gear ring 44 drives the switching gear 71 to rotate, and the wiping disc 75 faces the No. 2 circular hole. When the driven outer gear ring 44 rotates, it drives the No. 1 planetary gear 53 to make a circular motion around the No. 1 outer gear ring 51. The No. 1 planetary gear 53 rotates and drives the No. 1 inner gear ring 54 to rotate. The No. 1 inner gear ring 54 drives the installation toothed disc 55 to rotate. The installation toothed disc 55 with The second planetary gear 57 rotates to rotate the second inner gear ring 58, and the second inner gear ring 58 drives the self-cleaning smear assembly 6 to rotate. The sliding plate 45 moves backward to move the first outer gear ring 51, and the first outer gear ring 51 pushes the mounting toothed plate 55 to move through the second sliding column 52. The mounting toothed plate 55 rotates to rotate the mounting plate 68, and the mounting plate 68 drives the connecting ring 61 to rotate through the mounting ring 67. When the groove moves to the force block position, the smear sheet 63 moves forward to smear the gel on the fetal heart probe 10. When the inclined surface of the other end of the arc-shaped push block 42 moves to the force block position, the smear sheet 63 rotates to the position of the second circular hole and moves forward to be retracted. When the mounting ring 67 rotates, the driven gear 65 The ring 610 rotates, so that the second pulley 69 rotates, and the second pulley 69 drives the smear sheet 63 to rotate through the transmission belt 66, so that the gel is applied more evenly. After wearing, the waist support 11 supports the waist, and the wearing strap 84 is retracted into the shell 1. At this time, the rope column 36 rotates and drives the active gear ring 610 to rotate, so that the wiping disk 75 wipes the gel on the smear sheet 63 clean. After use, the wearing strap 84 is pulled again, and the self-cleaning smear component 6 repeats the above operation. At this time, there is no gel on the smear sheet 63, and the clean smear sheet 63 wipes the gel on the fetal heart probe 10 clean, and the smear sheet 63 rotates during the wiping process to make the wiping cleaner; during the detection process, the rotating component 9 drives the fetal heart probe The head 10 rotates, and during the rotation of the multiple fetal heart probes 10, ultrasonic waves are emitted and received from the fetal heart position from far to near, and then the ultrasonic signals are converted into electrical signals and transmitted to the signal amplifier. The signal amplifier amplifies the electrical signals and filters out high-frequency signals in the signals through filters, leaving the required low-frequency signals. The main control chip compares the waveforms of each fetal heart probe 10 at the same distance from the fetal heart, intercepts part of the waveform graph during the comparison, further aligns the peak values ​​of multiple waveform graphs and compares them, eliminates unreasonable data, and then takes the maximum value, minimum value and intermediate value after integrating multiple groups of valid data, displays the fetal heart data through the touch screen 2, and stores the fetal heart data of each detection in the storage module.
