A wearable fetal monitor

Abstract

The invention discloses a wearable fetal monitor, which is characterized in that it includes a shell 1, a shell 2, and a shell 3 connected to each other; the shell 2, and the shell 3 can be fixed on the abdomen of a pregnant woman through a strap Position, the housing 1 can be worn on the strap; the housing 1 is equipped with an ultrasonic transceiver module, an ultrasonic demodulation module, a fetal heart signal processing module, and a uterine pressure processing module. The housing 2 An ultrasonic transducer is arranged inside, and a pressure sensor is arranged inside the housing 3 . The casing 1 is also provided with safety protection modules such as a temperature monitoring module, a timing module, and a self-checking module. In the wearable fetal monitor provided by the present invention, the main unit (housing 1) of the fetal monitor can be worn on the puerpera or held in the hand, and the pregnant woman can perform fetal monitoring when standing or walking, and the fetal monitoring is more free; and the main unit There are also uterine pressure monitoring and safety protection modules inside, which are safer and more reliable.

Description

technical field [0001] The invention relates to the field of medical monitoring, in particular to a wearable fetal monitor. Background technique [0002] At present, the most widely used electronic fetal heart monitoring method in clinical practice is fetal heart contraction monitoring (Cardiocotography, CTG). When monitoring fetal heart rate and uterine contraction, it is necessary to record the fetal heart rate uterine chart in real time, including the fetal heart rate curve (fetal heart rate, FHR) and the uterine contraction curve (tocography, TOCO) of the mother's uterine pressure. Then, the doctor analyzes the fetal heart rate and uterine contraction curve according to certain standards, and then evaluates the health status of the fetus. [0003] Existing fetal monitors can be divided into two categories: wired probe monitoring and wireless probe monitoring. These two types of monitors include the host part. The difference lies in the way the probe collects fetal heart...

Problems solved by technology

[0004] The fetal monitor with wireless probe can free the mother from the shackles of cables and realize free monitoring, but there are still the following problems in use: the current wireless fetal heart rate monitoring probe can only collect fetal heart sound signals, and can only record fetal heart sound signals in real time. can be transmitted to the host computer, the host computer can accurately calculate the fetal heart rate

In addition, because the wireless probe integrates more circuits and is thicker, it needs to be fixed with a strap when using it. As a result, the probe is prone to rollover when the pregnant woman is standing or walking for monitoring, resulting in the loss of monitoring data.
