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.
Claims10
A dialysis system for delivering a treatment to a patient, comprising:
- a dialyzer for conducting dialysis of a patient;
- a patient control processor;
- a user interface control processor configured to receive a test display pattern from the patient control processor and to output an image corresponding to the test display pattern on a graphical output device;
- and
- an optical sensor configured to capture a brightness and a test display pattern timing on the graphical output device, wherein
- the patient control processor is configured to output an error signal if the brightness and the test display pattern timing captured by the optical sensor does not match an expected brightness and test display pattern on the graphical output device.
A method for delivering a treatment to a patient, comprising:
- using a user interface control processor to receive a test display pattern from a patient control processor used in a system for delivering a treatment for a patient to output an image corresponding to the test display pattern on a graphical display device;
- detecting the image displayed on the graphical display device by a camera with a view of the graphical display device, and generating a signal by the camera that is interpretable by the patient control processor;
- and,
- comparing the signal generated by the camera to templates to determine whether the image displayed on the graphical display device matches the templates or not;
- wherein the patient control processor is configured to output an error signal in response to the signal generated by the camera not matching the templates.
