Patient monitoring system
First Claim
1. A system for predicting or reporting when a patient stands up, comprising:
- a sock for a foot of the patient, the sock having one or more pressure sensors with conductive threads woven into the sock that change resistance according to pressure applied by the patient'"'"'s foot;
a monitoring device coupled to the sock, the monitoring device having;
one or more sensors configured to detect movement of the patient;
wherein the monitoring device begins processing data received from the one or more sensors when movement measured by at least one sensor of the one or more sensors exceeds a predetermined activation threshold;
wherein the monitoring device is configured to calculate a triggering value by combining the detected movement of the patient and changes in pressure detected by the pressure sensors;
wherein the monitoring device sends an alert message to a caregiver using an alert computer when the triggering value exceeds a predetermined alert threshold;
wherein the alert computer is coupled to a computer network, the alert computer configured to receive the alert message sent from the monitoring device and communicate the alert message to the caregiver; and
wherein the monitoring device stops processing data received from the one or more sensors when the movement measured by the at least one sensor of the one or more sensors has remained less than or equal to the predetermined activation threshold for greater than a predetermined activation timeout.

Abstract
A system for monitoring the movements or other activities of patient. Aspects include a monitoring device with one or more sensors such as a pressure or motion sensors that may be positioned on or near a patient. Alerts may be generated by the monitoring device if the sensor readings fall outside predetermined limits set in a patient profile specific to a particular patient. Sensor readings and/or alerts may be sent by the monitoring device to the central server which may notify nearby caregivers that a patient needs assistance. The server may be configured to analyze sensor readings and alert information to refine patient profiles to reduce or eliminate false alarms.

11. A method of detecting when a patient is about to stand up, comprising:
-
detecting movement of the patient using one or more movement sensors in a monitoring device on a sock worn on the patient'"'"'s foot, and at least one pressure sensor having conductive threads woven into the sock; activating the monitoring device to process movement detected by the one or more movement sensors, and pressure changes detected by the at least one pressure sensor, when the movement detected exceeds a predetermined activation threshold; using the monitoring device to obtain data values representing pressure and movement; processing the data to combine the pressure and movement data into a combined triggering value; comparing the combined triggering value to one or more predetermined alert thresholds that determine if the patient is moving, or is about to move, to an erect standing position; communicating an alert message to a caregiver when the processing output exceeds the predetermined alert thresholds; and deactivating the monitoring device to stop processing input from the gyroscope sensor and the pressure sensor when the acceleration measured by the accelerometer has remained less than or equal to the activation threshold for greater than a predetermined activation timeout. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
