C12468: Anatomic/Physiological Sensor Signal Generator for Clinical Monitoring DevicesNovelty:
A tool to generate and send simulated clinical sensor outputs to clinical monitoring devices.
Value Proposition:
Despite the advances in healthcare simulation technologies, many simulators still do not interface with clinical devices realistically. A realistic training environment, including clinically-relevant population of monitoring device screens, offers a better simulation-based model with which to train and complete research. There is currently no known device that allows for generated signals to replace signals from ETCO2, SPO2, thermometer, blood pressure, or NIRS sensors as inputs to clinical monitors/devices. This invention provides multiple means of signal generation and data encoding and transmission functionalities to realistically simulate diagnostic sensor inputs to clinical monitors/devices. Additional advantages of this technology include:
• Allows for control of waveform/values displayed on monitor
• Provides option of recording and replaying a signal
• Can be used with interactive devices to link provider actions with monitor display
Technical Details:
Johns Hopkins researchers have developed a technology to replace clinical sensors as the input to clinical monitoring devices. First, equations to create desired waveform shape are developed. As these numeric waveforms are plotted in real-time, the points are encoded according to manufacturer protocols. The encoded signal is, then, exported from the signal generating software module to the monitoring device, and the monitoring device receives and displays the simulated signal as if it were the real sensor signal. The current prototype generates and encodes an ETCO2 signal using an executable C# program on a PC, laptop, or tablet, and the digital signal is exported from the computer through a USB port to a defibrillator with monitoring capabilities.
Looking for Partners:
To develop and commercialize the technology as an anatomic/physiological sensor signal generator to be used with interfacing clinical monitors/devices.
