Patient-worn wireless physiological sensor
First Claim
1. A wearable wireless sensor for monitoring a thermal energy of a patient and at least one of pressure ulcer risk, fall detection, or fall risk, said wearable wireless sensor comprising:
- a housing including a predetermined position for at least a first sensor and a second sensor,one or more accelerometers responsive to an acceleration of said patient and configured to output one or more signals indicative of at least one of said pressure ulcer risk, said fall detection, or said fall risk;
a base including a first aperture;
a circuit layer including a first through-hole via extending through said circuit layer; and
a temperature sensor responsive to said thermal energy of said patient, said temperature sensor mounted on said circuit layer, said temperature sensor including a thermal contact in thermal communication with said circuit layer, wherein said temperature sensor is at least one of the first sensor or the second sensor;
wherein said first through-hole via is aligned with said thermal contact of said temperature sensor and with said first aperture of said base, said first through-hole via is configured to provide a structure to transmit said thermal energy across a length of the first through-hole via from said patient to said temperature sensor,wherein said first aperture and said first through-hole via include a thermally conductive material to cause said temperature sensor to be in thermal communication with a portion of said base corresponding to said first aperture, andwherein the housing is configured to operably position the base and the circuit layer.

Abstract
A wireless, patient-worn, physiological sensor configured to, among other things, help manage a patient that is at risk of forming one or more pressure ulcers is disclosed. According to an embodiment, the sensor includes a base having a top surface and a bottom surface. The sensor also includes a substrate layer including conductive tracks and connection pads, a top side, and a bottom side, where the bottom side of the substrate layer is disposed above the top side of the base. Mounted on the substrate layer are a processor, a data storage device, a wireless transceiver, an accelerometer, and a battery. In use, the sensor senses a patient'"'"'s motion and wirelessly transmits information indicative of the sensed motion to, for example, a patient monitor. The patient monitor receives, stores, and processes the transmitted information.
