Patient Monitoring System
A subject monitoring system operates to detect a current status of a subject in a subject arrangement area, such as on a bed, and predict an upcoming status of the subject. The system includes a subject status detection device that may use a radar signal. A radar signal is transmitted toward the subject and is used to detect a subject status, such as a subject position, a subject incontinence condition, and a physiological condition of the subject. One example of the radar signal includes a millimeter wave.

USPTO Full Text Publication >
- 1. A system for monitoring a subject status, the system comprising:
a subject arrangement area for arranging a subject thereon; a signal transmitter configured to transmit a radar signal toward the subject arranged on the subject arrangement area; a signal receiver configured to receive the radar signal; and a signal analysis device configured to detect a temporal variation of the radar signal and determine a subject status based on the temporal variation.
- 14. A method for monitoring a subject status, the method comprising:
arranging a subject in a subject arrangement area; transmitting a radar signal toward the subject; receiving the radar signal; monitoring a temporal variation of the radar signal; and determining a subject status based on the temporal variation.
- 20. A system for monitoring a subject status, the system comprising:
a processing device configured to control operation of the system; a signal transmitter configured to transmit a radar signal having a band of spectrum between 30 GHz and 300 GHz.; a signal receiver configured to receive the radar signal; and a computer readable storage medium storing software instructions that, when executed by the processing device, cause the system to:
transmit the radar signal toward a subject using the signal transmitter;
receive the radar signal using the signal receiver;
identify at least one body portion of the subject based on the received radar signal;
monitor a temporal variation of the radar signal;
predict an upcoming status of the subject based on the temporal variation; and
determine a wet spot around the subject based on the temporal variation.
