NONINVASIVE SLEEP SENSOR
This disclosure relates generally to a system for tracking sleep cycle of a person. More particularly, but not exclusively, one illustrative embodiment relates to a noninvasive system for determining sleeping state of a person.
There are a large number of people affected by sleep related conditions who could benefit from knowing more about their sleep habits. A sleep state can be examined as an indicator for determining the health condition of an individual. While various other systems for measuring sleep state information have been developed, there is still room for development. Thus a need persists for further contributions in this area of technology.
This disclosure provides a non-invasive sensing system to determine if a patient is either asleep or in a state of deep rest and relaxation. The system can simultaneously monitor the metabolic activities and the body movements of the person to determine the sleeping state passively. The system can include a plurality of sensors, a control unit and an output device. The plurality of sensors can be present on either on the person- support apparatus or on a headwall unit according to different embodiments of the disclosure. According to another embodiment of the disclosure, the plurality of sensors can also be present in a mattress assembly of the person-support apparatus. The real time information about the person's sleeping condition can be communicated to the output device where it can be stored, plotted, and shared with a physician to adjust a patient's medication.
Figure 1 show a block diagram of a sleep sensing system 10 installed on a person-support apparatus 12 according to an embodiment of the disclosure. The sensing system can include a plurality of sensors 14, a control unit 16 and output devices 18 and 20. The plurality of sensors 14 can include sensors for measuring metabolic activities of the person and the body movements of the person. The output from the plurality of sensors 14 can be given to the control unit 16. The control unit 16 can include an algorithm which can use output from the plurality of sensors 14 to determine whether the person is asleep or in a deep state of rest and relaxation. The

output from the control unit 16 can be communicated to the output devices 18 and 20. It should be appreciated that the output devices 18 and 20 can be a display device 18 for displaying the data and a printing device 20. It should also be appreciated that the control unit 16 can also communicate the data to a remote location, such as, a nursing station 22.
The noninvasive sleep sensing system 10 can include a first set of sensors 14a among the plurality of sensors 14 for measuring metabolic activities and a second set of sensors 14b among the plurality of sensors 14 for sensing body movements. When the person falls asleep, their metabolic rate can drop. This drop in metabolism can be detected in number of ways,...
