SYSTEMS AND METHODS FOR PATIENT FALL DETECTION
First Claim
1. A system for monitoring an orientation of a patient'"'"'s back to reduce a risk of the patient developing a pressure ulcer on a portion of the patient'"'"'s body, the system comprising:
- a sensor including an accelerometer, a processor, and a first wireless transceiver, said sensor configured to output a signal indicative of a possible change in an orientation of a back of said patient when said sensor is positioned on a portion of the patient'"'"'s back; and
a patient monitor comprising a signal processor, a memory device, a storage device, and a second wireless transceiver, said second wireless transceiver is configured to receive said signal from said sensor positioned on the portion of the patient'"'"'s back, and said signal processor is configured to process said signal to determine whether said possible change corresponds to an actual change in said orientation of the patient'"'"'s back, when said actual change has occurred, configured to record a patient turn event, to compare said patient turn event with a patient turn protocol, and when said possible change is not said actual change and no patient turn event occurs according to the patient turn protocol, said patient monitor is configured to notify a caregiver of a patient turn protocol violation,wherein said signal processor is configured to determine whether said possible change corresponds to said actual change includes being configured to determine a difference between said orientation of said patient'"'"'s back at a previous time and at a current time based at least on said signal, and when said difference is above a threshold, recording said patient turn event.

Abstract
A patient monitoring system to help manage a patient that is at risk of falling is disclosed. The system includes a patient-worn wireless sensor that can be affixed to the patient'"'"'s back that senses the patient'"'"'s motion and wirelessly transmits information indicative of the sensed motion to a patient monitor. The patient monitor receives, stores, and processes the transmitted information to determine whether the patient has fallen or is about to fall. Upon such detection, the system can notify the patient'"'"'s caretakers that the patient has fallen or is about to fall and therefore, is in need of immediate attention.
