  At this time, the user of the oxygen concentrator 1 can detect that a malfunction or the like has occurred in the apparatus due to the buzzer sound. Further, the user can confirm that a problem has occurred in the removable humidifier 21 or the like by visually recognizing the humidifying bottle alarm display unit 7a that is turned on in the operation unit 2 of FIG.

  As described above, in this embodiment, priority is given to the severity of alarms, and alarms indicating more serious malfunctions are preferentially lit, in which case other alarms are not lit. ing. For this reason, the alarm which should respond | correspond preferentially to a user can be shown, and it is the oxygen concentrator 1 which a user can also respond calmly.

Next, the process proceeds to ST16. In ST16, it is determined whether or not the humidifying bottle alarm guide switch 7b has been pressed.
Specifically, the humidifying bottle alarm determining unit (program) 34 is operated, and it is determined whether or not the humidifying bottle alarm guide switch 7b in FIG.
As described above, the humidifying bottle alarm guide switch 7b is configured to be turned on when the user depresses a portion such as a picture of the humidifying bottle in FIG.
Therefore, in ST16, it is determined whether or not the user has pressed down a portion such as a picture of the humidifying bottle in FIG.

When the humidifying bottle alarm guide switch 7b is turned on in ST16, the process proceeds to ST16, and a power supply alarm guidance sound is output from the sound output device 24.
Specifically, when the humidifying bottle alarm guide switch 7b is turned on, the audio output determining unit (program) 36 of FIG. 3 operates and the data in the humidifying bottle alarm guidance audio data storage unit 60 of FIG. , The data contents are output as voice from the voice output device 24 of FIG.
The humidifying bottle alarm guidance audio data is, for example, “Oxygen flow rate is low. Check the humidifying bottle”.
Therefore, the user who has heard this voice can quickly know how to deal with the malfunction of the oxygen concentrator 1.

  In this way, in ST12, the user who can visually recognize the lighting of the humidifying bottle alarm lamp and grasp the location of the trouble, etc., as in the past, examines the instruction manual etc. It is possible to obtain the coping method by voice guidance simply by pressing the surface of the humidifying bottle alarm display unit 7a without asking.

  Next, in ST21, flow rate data and the like are acquired in the same manner as in ST1, and in ST25, the same determination as in ST5 is made. If the second flow rate data is 50% or less and the pressure value is not 20 kPa or less, there is already a problem or the like. It is determined that the state has been removed, and in ST29, the humidifying bottle alarm lamp is turned off and the process ends. This is executed by operating the humidifying bottle alarm determining unit (program) 34 and the like.

Thus, the data in the tube alarm guidance voice data storage unit 58 and the like is an example of the handling information in the handling information storage unit. Further, in the present embodiment, the voice output device 24 outputs the tube alarm guidance voice data 58 which is the handling information by operating at least a part of the alarm display unit such as the tube alarm display unit 5. The tube alarm guide switch 5b or the like which is the switch part of the switch is operated.
Further, a buzzer sound, a chime sound, and the like are examples of alarm display sound information.

Further, in the present embodiment, as shown in FIG. 1 and the like, alarm types that are the alarms, for example, four types of alarms (tube alarm, power supply alarm, humidifying bottle alarm and communication alarm required) are classified for each type. A separate tube alarm display 5a and the like are arranged.
Therefore, the type of alarm generated by the user can be grasped quickly and without hesitation. Then, the user is guided only by pressing the lighted tube alarm display portion 5a or the like with a finger or the like, so the user can make a mistake in the coping method that matches the problem that has occurred. Can get without.

  Also, each of these alarms has a priority, and when an alarm with a high priority (high severity) is lit, the other alarms with low priority are not lit. Therefore, the configuration is such that the user can calmly deal with the alarms in descending order of priority.

Also, in this embodiment, there are problems that the user can specifically deal with by themselves (tube alarm, power supply alarm, humidifying bottle alarm, etc.) and problems that should be asked to experts by telephone (contact alarm required). Since it can be displayed separately and shown to the user, the oxygen concentrator 1 is very easy for the user to deal with.
The present invention is not limited to the above-described embodiments.
