Abstract:
On the basis of double criteria evaluation in terms of duration and cost of diagnostic study the conclusion is made on the effectiveness of the e-health systems for pregnancy surveillance using inexpensive cardiotocographic instrumentation and cloud technologies. To increase the reliability and robustness, as well as to reduce the complexity and cost of the fetal heart rate outpatient monitor as the key element in the system, a large part of measurement and diagnostic software is moved to the application server. The doplerogramm registration and transfer functionality remains at the client side of the spatially distributed monitor. The framework of the Doppler recording client is built using the pattern of a Storage Scope. Behavior of the objects within the framework is presented by the Harel state machine. Realization of the architecture of the Android platform is illustrated in detail by the client class diagram. The deployment of the realization on the Android-based communicator is shown also. The results obtained are the following. A double criteria approach to optimal selection of the outpatient pregnancy surveillance monitor option by the vector of a diagnostic study efficiency on the duration vs cost coordinate plane is suggested. Decomposition of the outpatient monitor software deriving the client component is done. The architecture of the Doppler outpatient monitor is designed, and the Android-based realization of the design is presented.
