Abstract
A medical treatment system is configured to output a predefined test pattern and to receive the signal by way of a microphone in order to test the volume and quality of the audio output in order to ensure the output audio signals effective to wake a sleeping patient. The failure of a processor to confirm the volume and fidelity of the audio output as well as the timeliness of the test pattern causes the processor to deny the resumption of a treatment and to generate an error signal.
Claims23
A dialysis system for delivering treatment to a patient, comprising:
- a user interface control processor configured to receive a test pattern from a patient control processor and to output on an audio output device;
- a microphone positioned to receive audio output from said audio output device and to generate an audio signal that is interpretable by the patient control processor and which audio signal can be compared to a predefined pattern to determine whether it matches the predefined pattern or not;
- and
- the patient control processor being configured to output an error signal if the audio signal does not match the predefined pattern.
(canceled)
A method for delivering treatment to a patient, comprising:
- using a user interface control processor, receiving a test pattern from a patient control processor and outputting a responsive signal on an audio output device;
- receiving audio, by a microphone positioned to receive audio output from said audio output device, and generating an audio signal that is interpretable by the patient control processor and which audio signal can be compared to a predefined pattern to determine whether it matches the predefined pattern or not;
- and
- using the patient control processor outputting an error signal if the audio signal does not match the predefined pattern.
(canceled)
A method for testing a treatment machine, comprising:
- using a processor, generating a test pattern from the processor and outputting a responsive signal on an audio output device;
- receiving acoustic energy by a microphone positioned to receive output from said audio output device and generating an audio signal representing the received acoustic energy, wherein the audio signal;
- using the processor, comparing the audio signal to a predefined pattern to determine whether the audio signal matches the predefined pattern or not;
- and
- using the processor, outputting an error signal if the audio signal does not match the predefined pattern.
