WIRELESS PATIENT MONITORING SYSTEMS AND METHODS
First Claim
1. A method to reduce a risk that a monitored patient will develop one or more pressure ulcers by pairing a wireless physiological sensor with a patient monitoring device in a caregiver environment where other wireless sensors may be paired with and communicating with other patient monitoring devices,the physiological sensor including a movement sensor, a first processor, and a first wireless transceiver, the physiological sensor configured to eventually be positioned with respect to a surface of said monitored patient to transmit information responsive to one or more of the patient'"'"'s movement, lack of movement, or both,the patient monitoring device including a second processor, a memory device, a storage device, a display, and a second wireless transceiver, the patient monitoring device responsive to the transmitted information from the physiological sensor to present to a caregiver patient information indicative of said risk of said pressure ulcers,the method comprising:
- in said physiological sensor, initiating a pairing mode of operation;
wirelessly transmitting from said physiological sensor a pairing signal configured to be effective for a pairing signal transmission range, said pairing signal including information identifying said physiological sensor;
in said physiological sensor, receiving a confirmation signal from said patient monitoring device confirming that said physiological sensor has been paired with said patient monitoring device;
in said physiological sensor, initiating a patient parameter sensing mode of operation; and
wirelessly transmitting to said patient monitoring device, a patient parameter sensing signal configured to be effective for a patient parameter sensing signal transmission range, said patient parameter sensing signal including information indicative of said risk of said pressure ulcers,wherein said pairing signal transmission range is configured to be substantially less than said patient parameter sensing transmission range.

Abstract
A patient monitoring system to help manage a patient that is at risk of forming one or more pressure ulcers is disclosed. The system includes a patient-worn wireless sensor that senses the patient'"'"'s orientation and wirelessly transmits information indicative of the sensed orientation to a patient monitor. The patient monitor receives, stores, and processes the transmitted information. It also displays and transmits information indicative of the patient'"'"'s orientation to help caregivers manage the patient'"'"'s risk of formation of one or more pressure ulcers. The system can identify the present orientation of the patient and determine how long the patient has been in the present orientation. If the patient remains in an orientation beyond a predefined duration, the system can notify the patient and/or caretakers that the patient is due to be repositioned.
