The measuring unit of the smart watch can measure the sound signal of the pregnant woman's abdomen to obtain the comprehensive heart rhythm information of the pregnant woman and the fetus. Then, the screening process can be used to filter the pregnant woman's heart rhythm information from the comprehensive heart rhythm information and obtain the fetal heart rhythm information alone to avoid the fetal heart rhythm information being confused by the comprehensive heart rhythm information, which provides effective monitoring for the fetal heart rhythm status.

2. By constructing a vibration measurement array with the watch's measurement unit and various auxiliary measurement units, the fetal movement position information can be detected, and the fetal position can be determined based on the fetal movement position information, which can effectively assist in reminding the fetus of abnormal position.

3. The timing function of the smart watch can be integrated to store the fetal movement position, fetal movement intensity, uterine contraction, maternal heart rate, maternal blood oxygen and fetal heart rate according to time parameters, providing long-term status analysis of the pregnant woman and the fetus to detect abnormalities in real time.

4. With a detachable smart watch, when fetal status detection is not needed, the smart watch can still be taken off and worn on the wrist.

5. By setting a variety of reference values, when a pregnant woman or fetus is in danger, a warning message can be output immediately to improve the safety of the pregnant woman and the fetus.

6. The measured information will be displayed through the display unit for the convenience of pregnant women or relatives and friends to view.

In view of the above technical features, the main effects of the method, device and abdominal wearable device for monitoring the status of pregnant women and fetuses using a smart watch can be clearly presented in the following embodiments.

Please refer to the first to fourth figures, which disclose the first embodiment of the device for monitoring the status of a pregnant woman and a fetus of the present invention, including an abdominal wearable device for monitoring the status of a pregnant woman and a fetus (hereinafter referred to as an abdominal wearable device 1) of the present invention, and a smart watch 2, to construct a vibration measurement array A. The device for monitoring the status of a pregnant woman and a fetus can also be used to execute a method for monitoring the status of a pregnant woman and a fetus using a smart watch of the present invention.

The abdominal wearable article 1 is worn on an abdomen B1 of a pregnant woman B, as shown in the sixth figure. In this embodiment, the abdominal wearable article 1 is a radiating adhesive member, and a plurality of radiating strips of the radiating adhesive member extend from a central position of the abdomen B1 to a peripheral position of the abdomen B1. Preferably, the central position refers to the vicinity of the belly button of the pregnant woman B, and the peripheral position surrounds the central position.

The abdominal wearable device 1 includes: a contact surface 11, an outer surface 12, a coupling portion 13 and a plurality of auxiliary measuring units 14.

The contact surface 11 is for contacting the abdomen B1, and the outer surface 12 is located opposite to the contact surface 11. The joint 13 corresponds to the central position, and the auxiliary measuring units 14 correspond to the peripheral positions. The auxiliary measuring units 14 each have an auxiliary measuring surface 141, and the auxiliary measuring surface 141 is located on the contact surface 11.

The smart watch 2 is selectively connected to the joint 13. Preferably, the smart watch 2 includes a watch body 21 and a watch strap 22. The auxiliary measuring unit 14 is signal-connected to the watch body 21, and the smart watch 2 is signal-connected to one or a combination of the following devices: a mobile phone 3, a tablet computer, and a computer. In the drawings of the present invention, only the mobile phone 3 is drawn in FIG. 8 for illustration.

After the smart watch 2 is removed from the strap 22 , the watch body 21 matches the coupling portion 13 , so that the coupling portion 13 can couple and fix the watch body 21 .

After the watch body 21 is combined with the combining portion 13 , a watch measuring unit 23 of the watch body 21 will be located on the contact surface 11 , and the watch measuring unit 23 and each of the auxiliary measuring units 14 together form the vibration measuring array A.

The watch measuring unit 23 itself can have a sound sensor element, an inertial measuring element and an optical measuring element 231, such as a microphone, a gyroscope, an infrared transceiver, etc., to perform different measurement functions. However, in the diagram of the present invention, only the optical measuring element 231 is drawn for illustration. The auxiliary measuring unit 14 can also be the inertial measuring element.

Please refer to Figures 4 to 6. When the pregnant woman B wants to execute the method of monitoring the status of the pregnant woman and the fetus with a smart watch, she first combines the watch body 21 with the abdominal wearable device 1, and wears the abdominal wearable device 1 on the abdomen B1, so that the watch measurement unit 23 is attached to the central position, and the auxiliary measurement unit 14 is attached to the peripheral position.

Please refer to FIG. 7 to FIG. 9 and refer to FIG. 4 and FIG. 5 . Then, the watch measuring unit 23 is used to measure a sound signal of the abdomen B1 , and the smart watch 2 obtains a comprehensive heart rate information C according to the sound signal.

The optical measuring element 231 is used to measure a pregnant woman's blood vessel in the abdomen B1 to obtain a pregnant woman's heart rhythm message D and a pregnant woman's blood oxygen message, and the pregnant woman's heart rhythm message D and the aforementioned comprehensive heart rhythm message C are subjected to a screening procedure 211 to filter the pregnant woman's heart rhythm message D from the comprehensive heart rhythm message C, and then filter out a fetal heart rhythm message E from the comprehensive heart rhythm message C.

However, measuring heart rhythm and blood oxygen with visible or invisible light, and judging heart rhythm from sound are all known technologies. People with general knowledge in the relevant technical fields can naturally configure them according to actual needs.

In addition, the vibration measurement array A can also be used to measure a vibration signal of the abdomen B1, and the smart watch 2 obtains a fetal movement message F and a uterine contraction message G according to the vibration signal.

The above-mentioned information can be displayed through a display unit, for example, directly displayed on the watch 21 as shown in the seventh figure, or displayed on the mobile phone 3 as shown in the eighth figure, for the pregnant woman B or relatives and friends to view, and can also be transmitted to a calculation unit, such as the watch 21 or the mobile phone 3, and the calculation unit will calculate with a pre-set fetal movement position reference value, a fetal movement intensity reference value, a fetal movement time reference value, a uterine contraction reference value, a pregnant woman's heart rate reference value and a fetal heart rate reference value.

For example, a fetal movement position deviation value between the fetal movement position information F1 and the fetal movement position reference value, a fetal movement intensity deviation value between the fetal movement intensity information and the fetal movement intensity reference value, a fetal movement time deviation value between the fetal movement time information and the fetal movement time reference value, a uterine contraction deviation value between the uterine contraction message G and the uterine contraction reference value, a pregnant heart rhythm deviation value between the pregnant heart rhythm message D and the pregnant heart rhythm reference value, and a fetal heart rhythm deviation value between the fetal heart rhythm message E and the fetal heart rhythm reference value can be calculated respectively.

When any one of the fetal movement position deviation, the fetal movement intensity deviation, the fetal movement time deviation, the uterine contraction deviation, the pregnant woman's heart rhythm deviation and the fetal heart rhythm deviation is greater than a preset value, the calculation unit outputs a warning message to the smart watch 2, the mobile phone 3, the tablet computer or the computer, so that the pregnant woman B or her relatives and friends can know it immediately and take action as soon as possible to improve the safety of the pregnant woman B and the fetus.

Please refer to FIG. 10 to FIG. 12 . Preferably, the fetal movement message F includes one or a combination of the following messages: a fetal movement position message F1 , a fetal movement intensity message, and a fetal movement time message.

Taking the fetal movement position information F1 as an example, the position where the fetal movement occurs can be located by the meter 21 by measuring the distance between the position where the fetal movement occurs and each of the auxiliary measurement units 14 and the meter 21, and the position where the fetal movement occurs can be used as the fetal movement position information F1, as shown by the footprints in the figure.

The fetal movement intensity information and the fetal movement time information may be the intensity average value and the time average value measured by the auxiliary measurement unit 14 and the meter 21, respectively, and the present invention is not limited thereto.

Based on the fetal movement position information F1 for several times, the fetal position can be further evaluated. For example, in the eleventh figure, the fetal movement is concentrated in the lower left of the abdomen B1, which may mean that the fetus is head up. When the fetal movement begins to disperse upward as in the twelfth figure, it means that the fetus may gradually turn head down. When the gestational age is higher, it is necessary to further evaluate whether delivery is imminent, whether the fetal position is abnormal, etc.

Please refer to Figure 13, which discloses a second embodiment of the device for monitoring the status of a pregnant woman and a fetus of the present invention. The difference between this embodiment and the first embodiment is that: in the first embodiment, the abdominal wearable article 1 is a radiant adhesive member [please refer to Figure 7 for the first embodiment]; while in this embodiment, the abdominal wearable article 1a is a belly band.

Similar to FIG. 7 , after removing the strap 22a of the smart watch 2a, the watch body 21a and the auxiliary measuring unit 14a can be attached to the abdomen B1 of the pregnant woman B with the belly band, and the required various information can be obtained like the device for monitoring the status of the pregnant woman and the fetus in the first embodiment.

The pregnant woman B can choose the abdominal band or the radiant adhesive according to the gestational age or her own condition. For example, when the gestational age is higher, the radiant adhesive can be selected first to avoid the discomfort of compressing the abdomen B1 during the measurement process.

Please refer to the first and eighth figures again. By using the detachable smart watch 2, when the fetal status detection is not needed, the smart watch 2 can still be taken off and worn on the wrist of the pregnant woman B, and will not be idle.

Combined with the description of the above embodiments, the operation, use and effects of the present invention can be fully understood. However, the above embodiments are only preferred embodiments of the present invention and should not be used to limit the scope of the implementation of the present invention. In other words, simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention description are all within the scope of the present invention.
