Patent attributes
A medical notification apparatus and method for use with a preexisting healthcare facility nurse call system are disclosed. The apparatus sends a message signal to the healthcare facility call system when the apparatus receives and identifies an acoustic signal indicative of a medical device alarm or other parameter. The apparatus comprises an acoustic sensor, a signal processing unit, and an interface unit. A band pass filter, timing gate, and a processor are configured in one embodiment to process the received acoustic signal to identify an acoustic alarm. A memory device may be used to store a set of identification criteria for identifying a variety of acoustic alarms, and to store a set of message signals. The sent message signal is selected from among the stored set of message signals.
