Design of a remote monitoring platform for uterine contraction pressure based on virtual instrument

With the development of computer technology, communication technology, and multimedia technology, more and more attention has been paid to remote medical monitoring platform. For the high cost and mobility issues in pregnancy checkups, a kind of remote monitoring platform for uterine contraction pressure based on Virtual Instrument is proposed in this article. Firstly, the article analyzes the importance and necessity of the medical monitoring platform, and then discusses the design of hardware circuit, micro-controller system and Laboratory Virtual Instrument Engineering Workbench (LabVIEW) program based on Virtual Instrument. Finally gives the experimental results for this platform. The remote monitoring platform is composed of three parts: signal acquisition and upload unit, monitoring server and remote signal download unit. The clinical validation experiment in hospital for this platform has been made and the experimental results shows that this platform complies with the trend that current medical system is becoming portable, homely and networked. Through the platform, doctors can download the uterine contraction pressure data collected and uploaded by the pregnant women at home. By observing the pressure curve generated from the data, doctors can know the physiological status of the pregnant women and provide diagnostic advices for them. And then, occurrence of prematurity and miscarriage can be prevented effectively.
