摘要：
The invention provides a monitor for measuring blood pressure and other vital signs from a patient without using a cuff. The invention provides a hand-held device for measuring vital signs (e.g. blood pressure) from a patient that features: i) a housing that encloses a first sensor, that includes a first electrode and a first optical system configured to generate a first optical signal ii) a second sensor that includes a second electrode and a second optical system configured to generate a second optical signal iii) an amplifier system, in electrical contact with the first and second electrodes, configured to processes electrical signals from the first and second electrodes to generate an electrical waveform and iv) a microprocessor, in electrical communication with the amplifier system, first optical system, and second optical system, the microprocessor configured to process the electrical waveform and first and second optical signals with an algorithm to determine at least one of the patients vital signs.
