MEDICAL TREATMENT DEVICE WITH SPEAKER SOUND DETECTION
First Claim
1. A medical treatment device for use in providing a treatment to a patient, the medical treatment device comprising:
- a speaker operable to broadcast one or more types of sounds, wherein the one or more types of sounds comprise at least one of an alarm sound and a test sound, wherein the alarm sound comprises a plurality of spaced apart notes with each note having a duration, an amplitude, and a frequency, wherein each test sound comprises a note having a duration, an amplitude, and a frequency, wherein each type of sound is associated with a predefined sound signature, wherein the sound signature corresponding to an alarm sound comprises criteria based at least on the amplitude and duration of at least two notes of the plurality of spaced apart notes, and further wherein the sound signature corresponding to a test sound comprises criteria based on the amplitude and duration of the note thereof;
an acoustic transducer to generate a sound signal representative of a sound when broadcast by the speaker; and
processing circuitry configured to;
command the speaker to broadcast a sound of the one or more types of sounds;
monitor and store the sound signal generated by the acoustic transducer during a time period when the speaker is expected to broadcast the sound; and
determine if the speaker was operable to broadcast the sound and whether the sound was audible to a user by comparing the stored sound signal to the sound signature associated with the type of sound commanded to be broadcast.

Abstract
Medical treatment devices and methods may include a speaker operable to broadcast one or more types of sounds, wherein each type of sound may be associated with a predefined sound signature. An acoustic transducer may be used to generate a sound signal representative of a sound when broadcast by the speaker. The speaker may be commanded to broadcast a sound of the one or more types of sounds, a sound signal generated by the acoustic transducer during a time period when the speaker is expected to broadcast the sound may be monitored, and it may be determined if the speaker was operable to broadcast the sound and whether the sound was audible to a user by comparing the stored sound signal to the sound signature associated with the type of sound commanded to be broadcast.

2. A method for a medical treatment device, wherein the medical treatment device comprises a speaker operable to broadcast one or more types of sounds, wherein the one or more types of sounds comprise at least one of an alarm sound and a test sound, wherein each alarm sound comprises a plurality of spaced apart notes with each note having a duration, an amplitude, and a frequency, wherein each test sound comprises a note having a duration, an amplitude, and a frequency, wherein the method comprises:
-
commanding the speaker to produce a sound of the one or more types of sounds, wherein each type of sound is associated with a predefined sound signature, wherein the sound signature corresponding to an alarm sound comprises criteria based at least on the amplitude and duration of at least two notes of the plurality of spaced apart notes, and further wherein the sound signature corresponding to a test sound comprises criteria based on the amplitude and duration of the note thereof; monitoring and storing a sound signal generated by an acoustic transducer during a time period when the speaker is expected to broadcast the sound; and determining if the speaker was operable to broadcast the sound and whether the sound was audible to a user by comparing the stored sound signal to the sound signature associated with the type of sound commanded to be broadcast.
