Abstract

A patient monitor can diagnose whether its speaker is blocked, malfunctioning, or at a volume that is too low. For example, the monitor can include a processor that can diagnose the speaker by recording a microphone input signal. The processor can compare the microphone input signal to an expected alarm signal that should be output by the speaker. If the two do not match or reasonably correspond to one another, then the processor may increase the volume of the alarm to determine whether doing so can overcome an obstruction, noise, or potential malfunction. The microphone can again detect the speaker output, and the processor can again make another comparison or analysis of the input with the speaker output. If the speaker output as detected via the microphone is still insufficiently loud, then the patient monitor may output an indication that the speaker has a problem.

First claim

What is claimed is:

1. A patient monitor device for monitoring a patient's physiology, the monitor comprising:
a cover configured to:
cover one or more ventilation holes on a housing of the monitor;
exist in an open position or a closed position; and
transition between said open and closed positions in response to a user actuation of the cover,

wherein in said open position, the cover is configured to:
support the monitor when the monitor is oriented in a vertical orientation; and

wherein in said closed position, the cover is configured to:
fit within an indentation of the housing of the monitor such that an outer surface of the cover is flush with an outer surface of the housing.

2. The patient monitor device of claim 1 , further comprising a hardware processor, wherein the hardware processor is configured to:
output an alarm to a speaker of the patient monitor;
while outputting the alarm to the speaker, receive a microphone signal from a microphone of the patient monitor;
determine that the microphone signal does not sufficiently match an expected alarm signal; and
responsive to said determining, output an error indication regarding the speaker.

3. The patient monitor device of claim 1 , further comprising a display for displaying information relating to the physiology of the patient, wherein the display is configured to display the information in a portrait mode or a landscape mode.

4. The patient monitor device of claim 3 , wherein the display is configured to:
display the information in the portrait mode in response to the monitor being in the vertical orientation; and
display the information in the landscape mode in response to the monitor being in a horizontal orientation.

5. The patient monitor device of claim 1 , wherein the cover is configured to rotate about a central axis of the cover to transition between the open and closed positions.

6. The patient monitor device of claim 1 , further comprising a speaker, wherein the speaker exists a first distance from a surface on which the monitor rests when the monitor is oriented in the vertical orientation, and wherein the speaker exists a second distance from the surface on which the monitor rests when the monitor is oriented in a horizontal orientation.

7. The patient monitor device of claim 6 , wherein the first distance is greater than the second distance.

8. The patient monitor device of claim 1 , wherein the cover is configured to not occlude the one or more ventilation holes on the housing of the monitor.
