Completed as part of the UNL ECE program in 2017 in partial fulfillment of requirements for a degree. Project Summary: The SVOS is a multiple-module system interfacing multiple medical devices with a single embedded system and a subsequent desktop system. The system is designed to interface with two specific pieces of medical equipment. The first is a Doppler ultrasound machine. The machine that was used for development was Acuson’s Sequoia 512 Ultrasound Machine. The output of this machine contains blood flow velocity data, but is encoded in a Doppler frequency shift. To keep the processing requirements of the embedded system low, analog signal processing is implemented to convert this Doppler shift to a useful blood flow velocity signal. The second piece of equipment employed by the development team was ADInstruments’ Human NIBP (Non-Invasive Blood Pressure) Controller System, which is driven using LabChart 8 software. While the NIBP system has a digital output capable of transmitting blood pressure directly into LabChart, for the context of this project, only the analog output of the NIBP is utilized for data transmission. This allows both data sets to be sampled nearly simultaneously and transmitted in matching frames to the computer system. The analog output of the NIBP system is a blood pressure waveform requiring minimal analog conditioning. Once both signals are conditioned, they are sampled using an external analog-to-digital converter and transmitted to the microcontroller unit for data formatting. Here, the data is assembled in frames and then transmitted to a Bluetooth or USB module for further transmission to the desktop system. In either case, data is collected by a special Python script and displayed using a custom-built Matlab Graphical User Interface.
