Description

Wearable device that monitors stress in pregnant women

The present invention relates to a wearable device that can monitor the stress of pregnant women, and in particular, a wearable device that can instantly help pregnant women monitor stress factors that are harmful to their physical and mental health, so as to maintain the healthy growth of the mother and the fetus.

According to the impact of the declining birthrate, parents attach great importance to the birth and growth process of their newborns, and pregnant women always take good care of their fetuses during pregnancy. Generally, pregnant women need to go to the hospital for regular prenatal checkups starting from the early stages of pregnancy. With the help of professional doctors and precision instruments, they can detect and observe whether the fetus's heart rate, fetal position, and growth are normal. In addition to preventing, treating or correcting various problems during the fetal period, it can also maintain the health of the expectant mother and the fetus.

For pregnant working women, busy work can easily cause great psychological pressure, making the birth process less safe and smooth than before, so the proportion of miscarriage has increased significantly; therefore, in order not to affect the daily routine of pregnant women and at the same time take into account the safety of pregnant women and fetuses, many fetal monitoring devices have been developed in the market, as follows: Announcement No. I5 No. 59903 "Fetal Sound Monitor" is suitable for wearing on the wrist of pregnant women. The detection unit is placed on the belly of the pregnant woman. The fetal sound detector can detect the physiological information of the fetus in the pregnant woman's abdomen and provide it to the doctor for reference to reduce the psychological pressure of the pregnant woman. It provides users with a considerate design that is convenient to carry and operate.

Publication No. 200918017 "Remote Physiological Monitoring Device", the device includes a blood pressure monitor, a blood oximeter, a chest respiratory physiological monitoring device or a lower abdominal uterine contraction physiological monitoring device. The physiological information measured by the device is transmitted remotely through a physiological monitoring transmission device so that medical staff can grasp the physiological condition of the subject at any time. Especially for patients with apnea or pregnant women in the late stages of pregnancy, the physiological condition can also be measured and recorded at home to achieve the effect of remote monitoring.

Publication No. 200945238 "Intelligent Pregnant Women's Home Real-time Monitoring and Communication System and Method" uses a sensing device to sense the physiological conditions of pregnant women such as uterine contraction and fetal heart rate and fetal movement, and generates a sensing signal; an intelligent computer-assisted monitoring system performs analysis and processing and generates an analysis signal; the analysis signal is then downloaded and displayed by the intelligent computer-assisted monitoring system via a remote electronic device. The analysis signal displayed by the electronic device can be used to determine whether the physiological conditions of pregnant women and their fetuses are abnormal; thereby, remote monitoring and real-time information on the physiological conditions of pregnant women can be obtained, reducing the trouble of pregnant women being hospitalized for a long time or frequently going back and forth to the hospital during pregnancy due to the need for fetal maintenance.

However, the above technologies generally monitor physiological aspects, but the psychological factors and stress of pregnant women can affect the fetus at any time. It is also known in medical reports that the stress of pregnant women can lead to health problems or death of pregnant women and fetuses. One of the reasons for high stress in pregnant women is that pregnant women release too much energy when they are at home or outdoors. Therefore, an invention is needed to monitor the stress level of pregnant women. At present, there is no wearable device that is both comfortable and does not interfere with pregnant women's activities, and can be used to prevent the decline of health of pregnant women and fetuses.

Therefore, the inventor has been adhering to the rich design development and actual manufacturing experience in the relevant industry for many years, and has continued to develop and research in the spirit of excellence, and has specially provided a wearable device that can monitor the pressure of pregnant women, in order to achieve the purpose of having better practical value.

The main purpose of the present invention is to provide a wearable device that can monitor the stress of pregnant women, especially a wearable device that can instantly help pregnant women monitor stress factors that are harmful to their physical and mental health, so as to maintain the healthy growth of the mother and the fetus.

In order to make the technical content, purpose of the invention and the effect achieved by the present invention more complete and clear, the following is a detailed description, and please refer to the disclosed diagrams and figure numbers: First, the actual application technology and means of the present invention, please refer to the first figure, which is a schematic diagram of the wearable device structure of the present invention that can monitor the pressure of pregnant women, which mainly includes: A bra body (1), which has two cups (11) and is worn on the chest of pregnant women; a microcontroller (2), which is fixed between the two cups (11) and can receive and transmit monitoring data and signals and analyze them; a set of respiration rate sensors (3) [Respiration Rate A sensor (RRS) is installed between the two cups (11) and connected to the microcontroller (2) to monitor and transmit the number of times the pregnant woman breathes per minute; an electrocardiography sensor (4) [Electrocardiography, ECG] is installed in the cups (11) and connected to the microcontroller (2) to monitor and transmit the physiological signals of the pregnant woman's heart rate and heart activity; a photocapacitance sensor (5) [Photoplethysmography, PPG] is installed in the cups (11) and connected to the microcontroller (2) to monitor and transmit the blood oxygen saturation data of the pregnant woman; a skin temperature sensor (6) [Skin Temperature A set of skin galvanic response sensors (7) [Galvanic Skin Response, GSR], installed in one of the cups (11) and connected to the microcontroller (2), used to measure and transmit data on the surface temperature of the pregnant woman's skin; A set of acceleration sensors (8) [Acceleration, ACC], installed in one of the cups (11) and connected to the microcontroller (2), used to measure and transmit data on the daily movement speed of the pregnant woman.

When implemented in practice, the bra body (1) is characterized in that six sensors are provided on the cup (11) as a tool for monitoring the stress and energy consumption of pregnant women. The cup (11) is also equipped with a microcontroller (2). The microcontroller (2) further includes a Bluetooth module (21) and a WiFi module (22), which can transmit the analyzed data to the back-end platform (9) wirelessly and obtain data through a smart mobile device (10) [such as a laptop, a smart phone] connected to the platform; and further includes a battery (23) that supplies the power required by the microcontroller (2). The selection of the bra body (1) material and the placement of the sensor will also affect the comfort and effectiveness of the wearable device during use; the following specific embodiments can further demonstrate the scope of practical application of the present invention, but it is not intended to limit the scope of the present invention in any form.

Please refer to the first and second figures. First, the microcontroller (2) is installed between the two cups of the bra body (1). Then, a belt (12) is provided between the two cups (11). Then, the breathing frequency sensor (3) is installed on the belt (12). Then, the electrocardiogram sensor (4) is installed in the right cup (11) of the bra body (1) in the form of an electrode patch. The photocapacitive sensor (5) is installed at the upper edge of the right cup (11). The skin temperature sensor (6) is installed at the upper edge of the left cup (11). Finally, the skin galvanic response sensor (7) and the acceleration sensor (8) are installed in the left cup (11) and arranged adjacent to each other.

When a pregnant woman wears the device, the sensors can contact her body. When the pregnant woman moves or touches anything in her daily life, the breathing frequency sensor (3) can monitor the number of times the pregnant woman breathes per minute, and a monitoring signal is generated and transmitted to the microcontroller (2); and the electrocardiogram sensor (4) monitors the physiological signals of the pregnant woman's heart rate and heart activity. The electrocardiogram sensor (4) is a kind of electrophysiological signal that records the electrophysiological activity of the heart in time units through the chest cavity. By using an electrode patch attached to the surface of the human skin, the potential transmission of the heart can be detected and the potential changes can be recorded in the form of an electrocardiogram. The results of the electrocardiogram are usually displayed in a waveform, and the data of the potential changes are generated as a monitoring signal and transmitted to the microcontroller (2).

At the same time, the photoelectric capacitance sensor (5) monitors the blood oxygen saturation data signal of the pregnant woman. The photoelectric capacitance sensor (5) is a non-invasive detection method that detects blood volume changes in living tissues by photoelectric means. A light beam of a certain wavelength is irradiated onto the skin surface of the fingertips. With each heartbeat, the contraction and expansion of the blood vessels will affect the transmission or reflection of the light, and then the light is converted into an electrical signal to obtain a monitoring signal and transmit it to the microcontroller (2); and the skin temperature sensor (6) monitors the skin surface temperature of the pregnant woman. The data signal of the degree of skin conductivity is then transmitted to the microcontroller (2); the skin galvanic response sensor (7) monitors the data signal of the pregnant woman's skin conductivity, and obtains emotional reactions by measuring the skin conductivity. However, strong emotional reactions will stimulate the nervous system, causing the sweat glands to secrete more sweat, and thus the monitoring signal is transmitted to the microcontroller (2); and the acceleration sensor (8) can monitor the data signal of the pregnant woman's daily life movement speed and transmit it to the microcontroller (2).

When the microcontroller (2) receives the monitoring signals of the sensors, it measures the heart rate variability (HRV) through the response signals of the electrocardiogram sensor (4) [ECG], the photocapacitive sensor (5) [PPG] and the galvanic response sensor (7) [GSR]. The heart rate variability [HRV] can be used to know whether the autonomic nervous system function is normal. In the human body, the stress source produces a stress response, which causes the autonomic nervous system to have heart rate variability [HRV]. The skin temperature sensor (6) [STS], the acceleration sensor (8) [ACC] and the respiratory rate sensor (3) [RRS] can monitor the energy consumption [energy consumption] of the pregnant woman. After pre-processing, feature extraction and classification analysis of heart rate variability [HRV] and energy expenditure [EE], the stress level data of pregnant women can be obtained. The stress level data is wirelessly transmitted to the back-end platform (9) via a Bluetooth module (21) or a WiFi module (22), and the data is obtained by connecting the back-end platform (9) via a smart mobile device (10) [such as a laptop, smartphone].

It is worth mentioning that the wearable device of the present invention can monitor the stress of pregnant women and has the function of monitoring the energy consumption of pregnant women. Since energy consumption is related to the daily activities of pregnant women, if the daily activities of pregnant women are too much, it will not only have adverse effects on pregnant women (causing fatigue), but also have adverse effects on the growth of the fetus; further, when the stress and energy consumption levels of pregnant women are too high, the wearable device of the present invention will be further equipped with an alarm [not shown in the figure] to issue a warning sound to remind the pregnant women.

However, the aforementioned embodiments or drawings do not limit the product structure or usage of the present invention. Any appropriate changes or modifications by those with ordinary knowledge in the relevant technical field should be considered as not departing from the patent scope of the present invention.
