Abstract
A method and device for masking noise from a dialysis machine, as an example of a medical device, includes tubing or a fluid container, or both, being connectable to a patient for flowing fluid to or from the patient, and one or more sensors configured to detect one or more patient parameters. The dialysis machine further includes a controller configured to determine a sleep state of the patient based on the one or more patient parameters detected by the plurality of sensors, and adjust a masking sound in response to the sleep state of the patient. The masking sound is activatable in response to noise generated during operation of the dialysis machine.
Claims30
A dialysis machine, comprising:
- tubing or a fluid container, or both, being connectable to a patient for flowing fluid to or from the patient;
- one or more sensors configured to detect one or more patient parameters;
- and
- a controller configured to:
- determine a sleep state of the patient based on the one or more patient parameters detected by the one or more sensors;
- and
- adjust a masking sound in response to the sleep state of the patient;
- wherein the masking sound is activatable in response to noise generated during operation of the dialysis machine.
A method for operating a dialysis machine, a patient being connected to tubing or a fluid container, or both, for flowing fluid to or from the patient, comprising:
- monitoring one or more patient parameters by one or more sensors;
- initiating a masking sound in response to noise generated during operation of the dialysis machine;
- determining a sleep state of the patient by a controller, based on the one or more patient parameters detected by the one or more sensors;
- and
- adjusting the masking sound by the controller in response to the sleep state of the patient.
