In general, bedsores (decubitus) refer to skin injuries caused by contact with the back, waist, shoulders, elbows, and buttocks of a patient lying in bed for a long time.

These symptoms of bedsores can be seen in patients who have been debilitated in bed for a long time or in patients who cannot freely change their position due to a disorder of the cerebrospinal nerve. They are more likely to occur in areas under pressure with weight, especially in areas where bones are exposed. In some cases, it can be caused by pressure from the cast.

The skin of the compressed area becomes pale at first because the blood circulation deteriorates, and the area around it becomes red and tender, and when it progresses further, blisters (blisters) are formed, and when it progresses further, it becomes dark and the area that causes gangrene. Is one of the very dangerous conditions in which odorous secretions come out by dropping out and forming ulcers.

For the above reasons, various measures have been provided to prevent bedsores, and Korean Patent No. 10-1054014, "A mattress for preventing bedsores," has been disclosed in the prior art, which is one of the measures for preventing such bedsores. This prior art supplies high-pressure air to an air cylinder device that is installed in a number of contact means that come into contact with the patient's back, and partially lifts the part that directly touches the patient's back, waist, shoulders, elbows, and buttocks. You can prevent bedsores by blowing air while giving it.

However, the prior art disclosed as described above does not have a great effect on bedsores due to contamination in the air after the period of use, and when a patient wears a diaper, there is a problem in that it is difficult to supply high pressure air to the wearing area.

<Setting mode of the control panel>

Hereinafter, the setting mode of the controller 300 will be described in detail with reference to FIG. 7.

Whenever a signal is input to the first button 361, the control PCB 340 sets a setting mode in the order of whether the oxygen generator 100 supplies oxygen, an oxygen supply time, and an oxygen supply section.

First, when a signal is input to the first button 361, the control PCB 340 may set a mode for setting whether to supply oxygen of the oxygen generator 100 (S1). At this time, the control PCB 340 turns on the valve 380 when a signal is input to the second button 363, and turns off the valve 380 when a signal is input to the third button 365. Meanwhile, when the oxygen generator is in the oxygen supply setting mode, a message of “Valve Test” is output on the display 370 to provide the user with a state of the oxygen supply setting mode.

After the valve 380 is turned on through the oxygen supply setting mode of the oxygen generator 100, the control PCB 340 sets the oxygen supply time setting mode when a signal is input to the first button 361. Can be (S2). At this time, when a signal is input to the second button 363, the control PCB 340 starts or pauses the oxygen supply time setting mode. In addition, when a signal is input to the third button 365, the control PCB 340 changes the set oxygen supply time to one of the times from 0 to 180 minutes. Meanwhile, when the oxygen supply time setting mode is in the display 370, the oxygen supply time (minutes, seconds) along with the message of "One Time" is outputted to provide the user with the state of the oxygen supply time setting mode.

After the oxygen supply time setting mode is set, the control PCB 340 may set the oxygen supply section setting mode when a signal is input to the first button 361 (S3). At this time, the control PCB 340 starts or pauses the oxygen supply section setting mode when a signal is input to the second button 363. Here, the oxygen supply section means a time region in which oxygen is supplied from the oxygen supply start time to the oxygen supply end time. For example, if the oxygen supply time is set to 60 minutes, the oxygen supply start time is set to 6:00 am, and the oxygen supply end time is set to 23:00 pm, the oxygen generator is from 6:00 am to 23:00 pm Oxygen from 100 may be supplied to the interior of the diaper 1. On the other hand, in the oxygen supply section setting mode, the oxygen supply start time and the oxygen supply end time (hours, minutes) together with the message of "Cycle" are output on the display 370 to provide the user with the setting mode status.

As such, the oxygen supply section setting mode includes a first time change mode for changing the time and minutes of the start of oxygen supply in the oxygen supply section and a second time change mode for changing the time and minutes of the end of oxygen supply.

Specifically, after the control PCB 340 is set to the oxygen supply section setting mode, a first time change mode for changing the time and minutes of starting oxygen supply when a signal is input to the first button 361 may be set ( S4). At this time, when a signal is input to the second button 363, the control PCB 340 changes the oxygen supply start time to at least one of 0 to 23 hours. In addition, when a signal is input to the third button 365, the control PCB 340 changes the oxygen supply start minute to at least one minute from 0 to 60 minutes. On the other hand, in the first time change mode, the time and minutes of the start of oxygen supply are output on the display 370 along with a message of “On Time” to provide the user with the state of the first time change mode.

After the first time change mode is set, the control PCB 340 may set a second time change mode to change the time and minute of the end of oxygen supply when a signal is input to the first button 361 (S5). At this time, when a signal is input to the second button 363, the control PCB 340 changes the oxygen supply end start time to at least one of 0 to 23 hours. In addition, when a signal is input to the third button 365, the control PCB 340 changes the oxygen supply end start minute to at least one of 0 to 60 minutes. Meanwhile, in the second time change mode, the time and minutes of the end of oxygen supply are outputted on the display 370 along with a message of “Off Time” to provide the user with the state of the second time change mode.

After the second time change mode is set, when a signal is input to the first button 361, the control PCB 340 returns to the oxygen supply setting mode of the oxygen generator 100 again.
