On July 05, 2016 , the USPTO issued U.S. Patent Number 9,384,652 to SPACELABS HEALTHCARE LLC, which was successfully prosecuted by Novel IP.
The '652 patent is directed towards methods and systems for transferring primary alarm notification on patient monitoring systems from a bedside monitor to one or more secondary devices which may operate on a less than fully reliable network. The bedside monitor includes an attached physiological parameter measurement device which detects when a specific physiological parameter measures outside a predetermined range. The bedside monitor then directs the secondary device(s) to annunciate its alarm. Primary alarming responsibility reverts from the secondary device(s) back to the bedside monitor whenever communication between the two is lost or when acknowledgement of the alarm condition by the secondary device is not relayed back to the bedside monitor within a predetermined amount of time.
Independent Claim 1 describes " A system for managing alarms in a medical environment, comprising: a secondary device adapted to generate a request for primary alarm responsibility from a bedside monitor, establish a consistent confirmation that a communication link between the secondary device and the bedside monitor is operational, and, when an alarm condition is detected, actuate an alarm and send an acknowledgement to the bedside monitor; and the bedside monitor adapted to receive the request for primary alarm responsibility from the secondary device, establish said consistent confirmation that the communication link between the secondary device and the bedside monitor is operational, and, if said acknowledgement from the secondary device is not received in a predetermined amount of time, retake primary alarm responsibility from the secondary device.
