Abstract
The invention features a vital sign monitor that includes: 1) a hardware control component featuring a microprocessor that operates an interactive, icon-driven GUI on an LCD; and, 2) a sensor component that connects to the control component through a shielded coaxial cable. The sensor features: 1) an optical component that generates a first signal; 2) a plurality electrical components (e.g. electrodes) that generate a second signal; and, 3) an acoustic component that generates a third signal. The microprocessor runs compiled computer code that operates: 1) the touch panel LCD; 2) a graphical user interface that includes multiple icons corresponding to different software operations; 3) a file-management system for storing and retrieving vital sign information; and 4) USB and short-range wireless systems for transferring data to and from the device to a PC.
