Abstract

The invention discloses a device and method for monitoring uterine contraction pressure in real time through a micro-motion sensor, and belongs to the technical field of medical instruments, and the device comprises a micro-motion signal acquisition device, a sending device connected with the micro-motion signal acquisition device, a processing device connected with the sending device, and a mobile terminal connected with the processing device.The device is light in weight and low in cost, and rapid and accurate monitoring of the uterine contraction pressure is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically relates to a device and method for real-time monitoring of uterine contraction pressure through a micro-motion sensor. Background technique [0002] At present, continuous fetal heart rate monitoring has been used clinically as a basic means of monitoring the safety of the fetus in utero. The fetal heart rate (FHR) can be monitored and measured to understand the development of the fetus and evaluate the health of the fetus. Cardiac electronic monitoring method is Doppler fetal heart contraction monitoring (Cardiocotography, CTG). [0003] However, the existing fetal / maternal monitors are not only expensive, but also costly for hospitals to purchase in large quantities; moreover, such devices are bulky, cannot follow the maternal activities, and are inconvenient to use. [0004] Secondly, because the mother's own health has a direct impact on the safety of the fetus ...

AI Technical Summary

Problems solved by technology

In general, the pressure sensor needs the transmission of the liquid level, and the process pressure needs the liquid level to be transmitted to the sensor. The liquid medium is packaged on the small contact surface of the pressure sensor. Medium leakage

The pressure of the load cell is transmitted through a beam. Due to the limitation of the volume of the beam, the volume of the load cell is relatively large after it is manufactured.

Although the use of a load cell does not require liquid medium packaging, and its linearity is relatively good after actual testing, but its volume is too large to meet the actual requirements, and the micro-motion sensor collects micro-motion signals, which have The following characteristics: height variation, irregularity, non-repeatability, etc.
