Description

Technical Field

[0001] This invention relates to the field of fetal heart rate monitoring technology, specifically to a fetal heart rate monitoring device. Background Technology

[0002] Fetal heart rate monitoring, also known as fetal heart rate, fetal movement, and uterine contraction monitoring, is a basic prenatal examination procedure that uses an electronic fetal heart rate monitor to record the fetal heart rate curve and fetal movement and uterine contraction pressure waveform to analyze the fetus's condition in the mother's womb. Fetal heart rate monitoring utilizes ultrasound to monitor the fetus's condition in utero and is a primary means of accurately assessing the fetus's condition within the womb.

[0003] However, existing fetal heart rate monitoring technologies have certain limitations. In addition to monitoring uterine contraction patterns, fetal heart rate monitoring mainly requires monitoring the fetal heart rate to determine the fetal status. Therefore, the probe used for fetal heart rate monitoring generally needs to be positioned relative to the back or chest of the fetus to collect relatively accurate fetal heart rate data. However, fetal heart rate monitoring usually requires 20-40 minutes of monitoring, during which the fetus needs to be relatively active, i.e., moving. However, fetal activity may also cause changes in the fetal position, resulting in poor monitoring results from the original monitoring position, which in turn makes it impossible to complete a single fetal heart rate monitoring session successfully. This leads to fatigue for the pregnant woman and also affects the monitoring efficiency. Therefore, a new fetal heart rate monitoring device is needed to address the shortcomings of existing technologies. Summary of the Invention

[0004] This invention proposes a fetal heart rate monitoring device that solves the problems of low monitoring efficiency and poor experience for pregnant women caused by the instability of the monitoring process in existing fetal heart rate monitoring devices.

[0005] The technical solution of the present invention is as follows:

[0006] A fetal heart rate monitoring device includes a processing module and a fixing strap. The monitoring module is connected to the processing module. The monitoring module has a monitoring surface for adhering to the position to be monitored. The fixing strap is used to fix the monitoring module. The monitoring module includes a fetal heart rate monitoring module and a uterine contraction monitoring module. The fetal heart rate monitoring module includes a central monitoring point and multiple annular monitoring zones with gradually increasing diameters centered on the central monitoring point. Each annular monitoring zone has multiple secondary monitoring points. The secondary monitoring points can move along the annular trajectory corresponding to the annular monitoring zone. The processing module acquires the monitoring value of the uterine contraction monitoring module and selectively acquires the monitoring value of one of the monitoring points on the fetal heart rate monitoring module.

[0007] The fetal heart rate monitoring module includes a monitoring bracket and multiple ultrasound probes. The monitoring bracket includes a star-shaped bracket and multiple ring-shaped brackets with progressively increasing diameters. The ring-shaped brackets are arranged sequentially on the star-shaped bracket with the center of the star-shaped bracket as the center. One of the ultrasound probes is located at the center of the monitoring bracket as the central monitoring point, and the other ultrasound probes are movably arranged on the ring-shaped bracket.

[0008] The number of ultrasonic probes on each of the ring supports increases sequentially.

[0009] The star-shaped support and the ring-shaped support are made of flexible materials that can be molded and deformed.

[0010] The fixing straps include a uterine contraction fixing strap and a fetal heart rate fixing strap. The uterine contraction fixing strap is connected to the top of the uterine contraction monitoring module to fix the uterine contraction monitoring module, and the fetal heart rate fixing strap is connected to the top of the ultrasound probe to fix the ultrasound probe.

[0011] The fetal heart rate fixation belt includes a main strap and a secondary strap. The main strap is composed of multiple straps with both ends converging at one point. The main strap is connected to the top of the ultrasound probe. One end of the secondary strap is connected to one end of the main strap, and the other end of the secondary strap is lockably connected to the other end of the main strap.

[0012] The uterine contraction monitoring module is a pressure monitoring device.

[0013] The working principle and beneficial effects of this invention are as follows:

[0014] This invention discloses a fetal heart rate monitoring device suitable for use by pregnant women during fetal heart rate monitoring. In use, the monitoring module is fixed to the pregnant woman's abdomen by a strap. The monitoring module is connected to a processing module to transmit signals. The monitoring module consists of a fetal heart rate monitoring module and a uterine contraction monitoring module. The position of the uterine contraction monitoring module is relatively fixed, and the fetal heart rate monitoring is easily affected by fetal movement. Therefore, based on the shortcomings of fetal heart rate monitoring, the fetal heart rate monitoring module is optimized by designing a central monitoring point at the center, with multiple annular monitoring areas of gradually increasing radius extending outward from the central monitoring point. Each annular monitoring area contains multiple secondary monitoring points. Thus, even if the fetus's position changes due to movement during monitoring, each monitoring point of the fetal heart rate monitoring module can capture the fetal heart rate according to the monitoring time period. The processing module can selectively acquire data, ensuring successful completion of fetal heart rate monitoring. This solves the problems of unstable monitoring process leading to low monitoring efficiency and poor experience for pregnant women in existing fetal heart rate monitoring devices.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-3 As shown in the figure, this embodiment proposes a fetal heart rate monitoring device, which includes a processing module 1 and a fixing strap. The monitoring module is connected to the processing module 1. The monitoring module has a monitoring surface for adhering to the position to be monitored. The fixing strap is used to fix the monitoring module. The monitoring module includes a fetal heart rate monitoring module 2 and a uterine contraction monitoring module 3. The fetal heart rate monitoring module 2 includes a central monitoring point and multiple annular monitoring areas with gradually increasing diameters centered on the central monitoring point. Each annular monitoring area is provided with multiple secondary monitoring points. The secondary monitoring points can move along the annular trajectory corresponding to the annular monitoring area. The processing module 1 acquires the monitoring value of the uterine contraction monitoring module 3 and selectively acquires the monitoring value of one of the monitoring points on the fetal heart rate monitoring module 2.

[0022] The fetal heart rate monitoring device in this embodiment is suitable for use by pregnant women when monitoring fetal heart rate. During use, the monitoring module is fixed to the pregnant woman's abdomen with a strap. The monitoring module is connected to the processing module 1 to transmit signals. The monitoring module consists of a fetal heart rate monitoring module 2 and a uterine contraction monitoring module 3. The position of the uterine contraction monitoring module 3 is relatively fixed. The monitoring of the fetal heart rate monitoring module 2 is easily affected by fetal movement. Therefore, based on the shortcomings of fetal heart rate monitoring, the fetal heart rate monitoring module 2 is optimized by designing a central monitoring point at the center. Multiple annular monitoring areas with gradually increasing radii are set outward from the central monitoring point. Each annular monitoring area contains multiple secondary monitoring points. Thus, even if the fetal movement causes a change in position during monitoring, each monitoring point of the fetal heart rate monitoring module 2 can capture the fetal heart rate according to the monitoring time cycle. The processing module 1 can selectively acquire data to ensure successful completion of fetal heart rate monitoring.

[0023] Furthermore, multiple secondary monitoring points set within the annular monitoring area can move within the annular region. The annular monitoring areas expand outwards from the central monitoring point, and by adjusting the positions of the secondary monitoring points, the monitoring ranges of the central monitoring point and each secondary monitoring point can complement each other, greatly improving the monitoring coverage. In actual operation, the optimal monitoring position can be manually found, and then the positions of the secondary monitoring points within the annular monitoring area can be adjusted. Operators can use experience to predict the possible direction or location of fetal activity and rationally arrange the positions of the secondary monitoring points. Processing module 1 obtains the monitoring values ​​from the uterine contraction monitoring module 3 to monitor uterine contractions. Simultaneously, processing module 1 also selectively obtains the monitoring value from one of the monitoring points on the fetal heart rate monitoring module 2. Initially, this is the central monitoring point. If fetal movement causes the position to shift, a reliable value is obtained from among the multiple secondary monitoring points as the monitoring value, thus achieving continuous monitoring and avoiding monitoring interruptions due to fetal movement.

[0024] The fetal heart monitoring module 2 includes a monitoring bracket 4 and multiple ultrasound probes 5. The monitoring bracket 4 includes a star-shaped bracket 6 and multiple ring-shaped brackets 7 with progressively increasing diameters. The ring-shaped brackets 7 are arranged sequentially on the star-shaped bracket 6 with the center of the star-shaped bracket 6 as the center. One of the ultrasound probes 5 is located at the center of the monitoring bracket 4 as the central monitoring point, and the other ultrasound probes 5 are movably arranged on the ring-shaped brackets 7.

[0025] In this embodiment, the fetal heart monitoring module specifically includes a monitoring bracket 4 and multiple ultrasound probes 5. The monitoring bracket 4 consists of two parts: a star-shaped bracket 6 and a circular bracket. The star-shaped bracket 6 is formed by multiple straight skeletons converging at one end to form a point. The ultrasound probes 5 are installed at the convergence point, i.e., the center position, of the star-shaped bracket 6 as the central monitoring point. Multiple ultrasound probes 5 are set on multiple ring brackets 7 with gradually increasing radii. The ultrasound probes 5 on the ring brackets 7 serve as secondary monitoring points. The ultrasound probes 5 can move along the ring brackets 7, thereby facilitating the adjustment of the monitoring position.

[0026] The number of ultrasonic probes 5 on each of the ring supports 7 increases sequentially.

[0027] In this embodiment, the number of ultrasonic probes 5 on the larger diameter annular support 7 can be more than the number of ultrasonic probes 5 on the smaller diameter annular support 7. Furthermore, as the diameter increases, the number of ultrasonic probes 5 also increases. The specific number can be flexibly selected according to the monitoring needs.

[0028] The star-shaped support 6 and the ring-shaped support 7 are made of flexible materials that can be molded and deformed.

[0029] In this embodiment, both the star-shaped bracket 6 and the ring-shaped bracket 7 are made of flexible materials that can be deformed. Initially, the fetal heart monitoring module 2 is fixed. By adjusting the shape of the star-shaped bracket 6 and the ring-shaped bracket 7, they are made to fit the pregnant woman's abdomen as closely as possible, so that each ultrasound probe 5 has a better fit.

[0030] The fixing band includes a uterine contraction fixing band 8 and a fetal heart rate fixing band 9. The uterine contraction fixing band 8 is connected to the top of the uterine contraction monitoring module 3 to fix the uterine contraction monitoring module 3, and the fetal heart rate fixing band 9 is connected to the top of the ultrasound probe 5 to fix the ultrasound probe 5.

[0031] The fetal heart fixation belt 9 includes a main strap 10 and a secondary strap 11. The main strap 10 is configured as multiple straps with both ends converging at one point. The main strap 10 is connected to the top of the ultrasound probe 5. One end of the secondary strap 11 is connected to one end of the main strap 10, and the other end of the secondary strap 11 is lockably connected to the other end of the main strap 10.

[0032] In this embodiment, the fixing straps are divided into a contraction fixing strap 8 and a fetal heart rate fixing strap 9, which respectively fix the contraction monitoring module 3 and the fetal heart rate monitoring module 2. The contraction monitoring module 3 is relatively stable and can be fixed by the contraction fixing strap 8. The fetal heart rate fixing strap 9 is divided into a main strap 10 and a secondary strap 11. The main strap 10 matches the fetal heart rate monitoring module 2. The main strap 10 is designed as multiple straps, which are connected to the ultrasound probe 5 for fixing it. The two ends of the multiple main straps 10 converge together, forming converging endpoints. One end of the secondary strap 11 is connected to the converging end of the main straps 10, and the other end can be locked to the other converging end. In possible implementations, both the contraction fixing strap 8 and the secondary strap 11 are locked by a buckle connection, with multiple buckle holes to adjust the tightness of the lock. In addition, Velcro can also be used for locking, allowing for a more precise adjustment range.

[0033] The uterine contraction monitoring module 3 is a pressure monitoring device.

[0034] In this embodiment, the working module uses a pressure detection device to determine the uterine contraction status by collecting changes in pressure values.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
