Body-worn vital sign monitor
First Claim
1. A vital sign monitoring system configured to be worn on the patient'"'"'s body and comprising:
- a least one vital sign sensor configured to generate and transmit a time-dependent vital sign waveform; and
a vital sign monitor configured to be worn on the wrist of the patient and comprising;
a housing,a motion sensor within the housing configured to measure a time-dependent motion waveform,a display device on a surface of the housing, anda processing component within the housing comprising a microprocessor, wherein the microprocessor comprises a first interface operably connected to the vital sign sensor to receive the time-dependent vital sign waveform, a second interface operably connected to the motion sensor to receive the time-dependent motion waveform, and a third interface operably connected to the display device,wherein the microprocessor is configured to (i) collectively process the time-dependent motion waveform and the time-dependent vital sign waveform, (ii) determine using the time-dependent motion waveform an orientation of the vital sign monitor and in response control an orientation of a graphical user interface displayed on the display device, wherein the orientation of the graphical user interface comprises a first orientation directed towards the patient and a second orientation directed away from the patient, and wherein the graphical user interface displays different information in the first orientation as compared to that displayed in the second orientation, (iii) determine using the time-dependent motion waveform a degree of motion of the patient'"'"'s wrist, (iv) determine using the time-dependent vital sign waveform and the degree of motion of the patient'"'"'s wrist a vital sign value, and (v) display the vital sign value or a parameter calculated therefrom on the display device through the third interface.

Abstract
The invention provides a body-worn vital sign monitor that measures a patient'"'"'s vital signs (e.g. blood pressure, SpO2, heart rate, respiratory rate, and temperature) while simultaneously characterizing their activity state (e.g. resting, walking, convulsing, falling) and posture (upright, supine). The monitor processes this information to minimize corruption of the vital signs and associated alarms/alerts by motion-related artifacts. It also features a graphical user interface (GUI) rendered on a touchpanel display that facilitates a number of features to simplify and improve patient monitoring and safety in both the hospital and home.
