Description

Monitoring device for simultaneous monitoring of maternal and fetal heart rate

The present invention relates to a monitoring device, in particular to a monitoring device that can monitor the heart rhythm of the mother and the fetus at the same time.

When a pregnant woman is pregnant, the fetal heart rhythm is often an important indicator to check whether the fetus is healthy. The so-called heart rhythms refers to the frequency of heart contractions (beats) and the number of beats per minute (bpm). Generally, adults are normal. The normal heart rate of the fetus is 120~160 beats per minute. If it exceeds 160 beats, it means that the heart rate is too fast, so you must pay attention to it. During the process of waiting for the formation of the fetus, pregnant women must regularly go to medical institutions for testing to confirm the growth of the fetus in the womb. Among them, electrocardiography equipment is a common detection method used to detect heart rhythm. By pasting electrode patches on pregnant women, the electrocardiogram In order to show the potential changes of the heart, and to further understand whether the heart rhythm is normal.

The heart is the main source of power to incite blood flow, provide systemic nutrition and carry away waste. For the fetus, the heart is also an early functional organ in the development of the whole body. Through heartbeat sensing, not only the survival of the fetus can be confirmed, but also the Judging from the fetal heart sound whether the condition is normal or not. When the heart rate is too high, it may be caused by the fetal hypoxia in the uterus or the pregnant woman’s own fever, and the heart rate is too fast. When the heart rate is too low, it is more likely to be related to congenital heart Diseases related to the internal organs, or caused by the development of the nervous system. Because the fetus obtains energy through the oxygen and nutrients delivered by the umbilical cord, and the organs of the whole body still need to develop and grow, and the functions are not perfect, special attention is often required before birth. Therefore, if the fetal heartbeat status can be observed at all times through external instruments, it can be sent to the doctor in time for treatment in case of a situation, and the probability of a healthy and smooth birth of the fetus can also be improved.

In addition, in the process of pregnancy, in order to conceive the fetus, the mother's body undergoes great physiological changes. In order to supply the mother and the fetus with sufficient blood and nutrients at the same time, this will cause a great burden on the mother's heart. During pregnancy, it will increase. 30% to 50% of the blood volume, therefore, the maternal heart output power must increase by 30% to 50% per minute. Compared with not pregnant, the heart rate of pregnant women will increase. During pregnancy, due to hormones and plasma coagulation factors The risk of thrombosis is much higher than that of non-pregnant women of the same age, and it may even increase by 14 times during the puerperium, leading to the risk of pulmonary embolism during childbirth. Monitoring of maternal heart rhythm during this period is also very important.

Generally, when a pregnant woman undergoes an obstetric examination, it can be tested by an electrocardiogram device in a medical institution to check whether the heart and body of the mother and fetus are healthy. However, there is only one obstetric examination per month on average. Therefore, when there is no obstetric examination, unless the pregnant woman is quite Sensitive, otherwise abnormal conditions of the mother itself or the fetus may not be detected in time, resulting in medical personnel unable to assist in the disposal at the first time, missing the golden rescue period. Therefore, after observing the above-mentioned shortcomings, the inventor of the present case believes that there is still a great risk in pregnant women only relying on the existing regular obstetric examination, and further improvement is necessary, and the present invention comes into being.

The purpose of the present invention is to provide a monitoring device that can monitor the heart rhythm of the mother and the fetus at the same time, and can provide a real-time monitoring device for long-term tracking. Remote monitoring provides real-time monitoring.

In order to achieve the above object, the present invention provides a monitoring device that can monitor the heart rhythm of the mother and the fetus at the same time, which includes; a fixing unit, which can be worn and fixed on the abdomen of the mother; a heart rhythm sensing module, Set on the fixed unit, it includes at least one first sensing unit and at least one second sensing unit, wherein the first sensing unit is located in the abdomen of the mother and is close to the position between the mother's heart and the fetus, so that The sensing unit can simultaneously sense the heart rhythm of the mother and the fetus and convert it into a potential output signal through the heart rhythm sensing module, and the second sensing unit is located in the lower abdomen of the mother and away from the mother's heart, so that the first Two sensing units can sense the heart rhythm of the fetus and convert it into a potential output signal through the heart rhythm sensing module; a filtering arithmetic processing unit is set on the fixed unit, the filtering arithmetic processing unit and the heart rhythm sensing module The electrical connection can obtain the potential output signal of the heart rhythm sensing module, and after filtering and computing by the filtering operation processing unit, the heart rhythms of the mother and the fetus are separated, and then output; a display unit is connected to the The filtering operation processing unit is electrically connected, so that the heart rhythms of the mother and the fetus outputted by the filtering operation processing unit can be remotely obtained and displayed on the display unit.

The monitoring device that can monitor the heart rhythm of the mother and the fetus at the same time provided by the present invention can simultaneously display the heart rhythms of the mother and the fetus on the display unit, and provide real-time heart rate and heartbeat information at any time. The role of monitoring to ensure the health and safety of the mother and the fetus.
