APPARATUS AND METHOD FOR ACOUSTIC ALARM DETECTION AND VALIDATION
First Claim
Patent Images
1. An alarm detection and validation device for validating acoustic alarms that have been generated by a medical device, the alarm detection and validation device comprising:
- a microphone arranged to output a first signal corresponding to audio detected by the microphone;
an alarm sound database containing audio signals corresponding to known alarm sounds, including the acoustic alarms able to be generated by the medical device; and
a processing unit arranged to;
receive the first signal from the microphone;
receive a second signal from the medical device indicating that the medical device has generated an acoustic alarm;
analyze the first signal to determine whether the detected audio includes the acoustic alarm generated by the medical device by comparing the detected audio to the audio signals in the alarm sound database so as to identify known alarm sounds included in the detected audio; and
output a third signal to the medical device based on the result of the determination, if the result of the determination is that the detected audio includes the acoustic alarm generated by the medical device.

12. A method for validating an acoustic alarm generated by a medical device, the method comprising:
-
(a) providing a microphone arranged such that sound emitted by a loudspeaker configured to emit acoustic alarms generated by the medical device will be included in audio detected by the microphone; b) providing an alarm sound database containing audio signals corresponding to known alarm sounds, including the acoustic alarms able to be generated by the medical device; (c) providing a processing unit in communication with both the medical device and the microphone; (d) generating an acoustic alarm with the medical device; (e) notifying the processing unit of the generation of the acoustic alarm; (f) detecting audio with the microphone; (g) analyzing, with the processing unit, the detected audio to determine whether it includes the acoustic alarm generated by the medical device by comparing the detected audio to the audio signals in the alarm sound database so as to identify known alarm sounds included in the detected audio; and if it is determined in (g) that the detected audio includes the acoustic alarm generated by the medical device; (h) outputting, with the processing unit, a signal to the medical device based on the result of the determining. - View Dependent Claims (13, 14)
