US Patent 9558648 Apparatus and method for monitoring hygiene

Method and apparatus for monitoring and reporting hand washing at a sanitizing station employs a sensor for signaling the dispensing of a sanitizer from a dispenser and a sensor module detecting the direction of passage of an individual into and out of a portal, such as the entrance to a sanitary area. The apparatus operates in a normal mode and a bypass mode. In the normal mode, the apparatus responds to the sensor indicating that an individual has not dispensed sufficient sanitizer to mitigate the spread of germs from care giver/health care worker to patient, and sounds an alarm when the individual passes through the portal in a particular direction, for example into or out of the sanitary area. Separate signals can be generated and recorded for each direction of passage through the portal. In the bypass mode, the alarm is not sounded and allows passage into and out of the sanitary area when a sanitary condition is not needed.
