    摘要: The invention features a vital sign monitor that includes: 1) a sensor component that attaches to the patient and features an optical sensor and an electrical sensor that measure, respectively a first and second signal: and 2) a control component. The control component features: 1) an analog-to-digital converter configured to convert the first signal and second signal into, respectively, a first digital signal and a second digital signal; 2) a CPU configured to operate an algorithm that generates a blood pressure value by processing with an algorithm the first digital signal and second digital signal; 3) a display element; 4) a graphical user interface generated by computer code operating on the CPU and configured to render on the display element the blood pressure value; and 5) a software component that renders video images on the display element. To capture video and audio information, the device further includes both a digital camera and a microphone.

    摘要: The invention provides a method for measuring a patient's blood pressure featuring the following steps: 1) measuring a first time-dependent optical signal with a first optical sensor; 2) measuring a second time-dependent optical signal with a second optical sensor; 3) measuring a time-dependent electrical signal with an electrical sensor; 4) estimating the patient's arterial properties using either the first or second time-dependent optical signal; 5) determining a pulse transit time (PTT) from the time-dependent electrical signal and at least one of the first and second time-dependent optical signals; and 6) calculating a blood pressure value using a mathematical model that includes the PTT and the patient's arterial properties.
