FIG. 1 is a diagram showing an embodiment of the present invention. The presence of a plurality of home oxygen therapy patients P1 to P8 within a certain regional area 100 is shown.

The plurality of home oxygen therapy patients P1 to P8
Are provided with a respiratory gas supply or oxygen concentrator. This oxygen concentrator is a PHS (Personal han
With the dy phone system function, the mobile telephone is connected to the mobile switching center 1 via the base station of the corresponding cell, and further connected to the management center 3 through the PHS network or the public telephone network 2.

The exchange 1 is provided with a location information database 4, and stores registration data of oxygen concentrators existing in the PHS cell area for each PHS base station. One P
The radius of the HS cell is 100 to several hundred meters. Therefore, the location of the oxygen concentrator registered and stored in the location information database 4 is 100 to several tens in correspondence with the corresponding base station.
It can be specified in a distance range of 0 m.

On the other hand, the management center 3 is provided with a patient database 5 in which the machine number of the oxygen concentrator and the name, address, medical history, etc. of the patient using it are stored.

FIG. 2 is a schematic structural view of an example of an oxygen concentrator used at home by oxygen therapy patients P1 to P5, and is an apparatus using an adsorbent capable of selectively adsorbing nitrogen as oxygen concentrating means. .

In FIG. 2, air supplied by a pump 10 is supplied to an adsorbent 11 which is a means for enriching oxygen and can selectively adsorb nitrogen. Here, the oxygen from which nitrogen has been absorbed and removed is guided to the humidifier 13 through the supply path 12. Oxygen-enriched air is supplied from the humidifier 13 to the patient through the nasal cannula 14. Further, the oxygen concentrator shown in FIG. 2 includes an oxygen supply controller 15 and a main body control device 16 according to the present invention.

FIG. 3 is a block diagram showing an example of the configuration of the oxygen supply controller 15 and the main body controller 16 of the oxygen concentrator shown in FIG. The main body control device 16 includes a microprocessor or CPU (hereinafter simply referred to as CPU) 200, a ROM
201 and a RAM 202 are connected by a bus.

The input setting unit 203 is operated by the oxygen therapy patient, and inputs a set oxygen flow value. The set oxygen flow value is displayed on the display unit 205.

The CPU 200 calculates a valve opening corresponding to the input oxygen flow rate value by a program stored in the ROM 201. Further, under the control of the CPU 200, a control signal corresponding to the calculated valve opening is sent to the oxygen supply controller 15 through the interface 204.
The oxygen supply controller 15 has a valve (not shown), and sets the valve to the valve opening indicated by the control signal. Thereby, oxygen is supplied to the oxygen therapy patient at the set oxygen flow rate.

Further, the RAM 2 in the main body controller 16
02 records the set oxygen flow value at predetermined intervals.
The recorded oxygen flow rate value can be displayed on the display unit 205.

The CPU 200 calculates the supplied oxygen amount from the oxygen flow rate value recorded in the RAM 202 and the time during which the valve was opened, and stores the calculated oxygen amount in the RAM 202.

The main controller 16 further has a PHS function unit 206. The PHS function unit 206 is connected to a switching center via a wired interface, and is connected to a base station arranged in units of cells by wireless connection to a PHS (Personal Handy Phone System).

Information data, such as the amount of oxygen remaining in the cylinder 1 and the amount of oxygen supplied per predetermined time, calculated according to 00, are periodically transmitted to the management center 3 described above.

When the oxygen concentrator shown in FIG. 2 is used at home, home electric power and a normal telephone line can be easily used. Therefore, the PHS function unit 206 as a communication means in the main body control device 16 may be replaced with a telephone modem so that information data is directly sent to the management center 3 through the public network.

FIG. 4 is a processing flow of the management center 3 as one embodiment of the present invention.

When the occurrence of a disaster is recognized by a notification from a disaster center (not shown) or the like (processing step P1), it is determined whether or not the signal transmission from the oxygen concentrator used by the oxygen therapy patient is continued (processing step). P2).

If the signal transmission is continued, it is determined whether or not abnormal data has occurred (processing step P3). At this time, if there is abnormal data, it is determined as a failure of the device (processing step P3, YES).

If the signal transmission is not continued (NO in the processing step P2), and furthermore, if it is determined in the processing step P3 that a failure has occurred in the equipment, urgent assistance to the patient is necessary.

The management center 3 obtains information on a patient for whom emergency support is determined to be necessary, that is, one piece of information in which an oxygen concentrator is arranged (processing step P4). This is obtained from the location information database 4 or the patient database 5 of the mobile switching center 1 described in Expression 1.

Next, from the machine number used by the relevant patient stored in the patient database 5, an emergency oxygen cylinder deployment station located at the shortest distance to the patient's home is searched (processing step P5).

At this time, the search with the shortest distance (delivery route) can be obtained by the shortest route search algorithm (Dijkstra method). Based on the delivery route searched in this way, an oxygen cylinder delivery instruction is performed, and an emergency oxygen cylinder is delivered (processing step P6).

FIG. 5 is a screen example of a monitor device (not shown) in the management center 3, in which patients and emergency oxygen cylinder deployment stations SC1 and SC2 are displayed. Also. Patients requiring emergency support are indicated by blacked-out patient symbols (P8) in the figure. In the figure, the line connecting the patient and the emergency oxygen cylinder deployment stations SC1 and SC2 indicates the shortest distance (route) searched between them.
