HAND-HELD MONITOR FOR MEASURING VITAL SIGNS
First Claim
1. A monitor for measuring blood pressure from a patient comprising:
- a housing comprising a first surface;
a first sensor comprised by the first surface, the first sensor comprising;
i) an optical system comprising at least one light source that generates optical radiation, and a photodetector oriented to collect radiation after it irradiates the patient and in response generate an optical signal; and
ii) a first electrode;
a second sensor comprising a second electrode paired with the first electrode and configured to collect an electrical signal from the patient; and
a microprocessor in electrical communication with the first and second sensor, the microprocessor configured to receive the optical and electrical signals and process these signals with an algorithm to determine systolic and diastolic blood pressure.

Abstract
The invention provides a monitor for measuring blood pressure and other vital signs from a patient without using a cuff. The monitor features a housing with a first surface that, in turn, supports a first sensor. The first sensor features: i) an optical system with one or more light sources (e.g., LEDs or laser diodes) that generate optical radiation, and a photodetector oriented to collect radiation after it irradiates the patient and in response generate an optical signal; and ii) a first electrode. A second sensor features a second electrode paired with the first electrode that collects an electrical signal from the patient. A microprocessor in electrical communication with the first and second sensor receives the optical and electrical signals and processes them with an algorithm to determine systolic and diastolic blood pressure.
