A concentrated oxygen pressurization device and a concentrated oxygen pressurization method according to an embodiment of the present invention will be described.

The concentrated oxygen pressurization device and concentrated oxygen pressurization method of the present invention are devices or methods for supplying concentrated oxygen to artificial respirators or/and anesthesia devices. Artificial respirators and anesthesia devices are used for humans, dogs, cats and other animals.

As shown in FIG. 1, the concentrated oxygen pressurizing device 10 mainly includes an oxygen concentrator 12, an oxygen supply flowmeter 14 and a purge flowmeter 16, a pressure-increasing compressor (supercharger) 18 and a residual pressure relief bidirectional valve 20 and the check valve 22 and the concentrated oxygen tank 24 and the pressure gauge 26 in the tank and the pressure sensor 28 and the relief valve 30 and the pressure regulator 32 and the pressure regulator 32 and the output pressure gauge 34 and artificial respiration The device connecting portion 36 and the anesthesia device connecting portion 38.

Specifically, on the upstream side of the oxygen enrichment tank 24, an oxygen concentrator 12 and an oxygen supply flowmeter 14 and a purge flowmeter 16 and a booster compressor (supercharger) 18 and a residual pressure release bidirectional valve 20 and止回阀22. Further, on the downstream side of the oxygen-enriched gas tank 24, an in-tank pressure gauge 26, a pressure sensor 28, an exhaust valve 30, a pressure regulator 32, an output pressure gauge 34, a respirator connection portion 36, and an anesthesia apparatus are arranged Connector 38.

In addition, each configuration of the oxygen-enriched pressure boosting device 10 is connected to each other through air flow paths 11 and 13 such as pipes. Therefore, the concentrated oxygen supplied from the oxygen concentrator 12 flows through the air flow paths 11 and 13 and moves to each constituent part. In the present embodiment, for convenience of description, all air flow paths located on the upstream side of the oxygen enrichment tank 24 (oxygen concentrator 12 side) are shown as upstream air flow paths 11 and oxygen concentration is located on the upstream side. All the air flow paths on the downstream side of the tank 24 (respirator 40 and anesthesia device 42 side) are shown as the downstream air flow path 13.

The oxygen concentrator 12 is a device that supplies concentrated oxygen. The oxygen concentrator 12 uses, for example, a general H-16 type. The discharge flow rate of the oxygen concentrator 12 is usually 10 L/min, but it is adjusted to 25 L/min by a flow regulating valve. The pressure of the concentrated oxygen supplied from the oxygen concentrator 12 is, for example, about 0.13 MPa.

Here, the discharge flow rate of the oxygen concentrator 12 is usually 10 L/min, but is adjusted to 25 L/min by the flow regulating valve. That is, for example, when not only the artificial respirator 40 but also the anesthesia device 42 are used in combination, the oxygen concentration needs to be reduced to about 25 to 30%, so the excess oxygen needs to be blown at about 20 L/min, for example Into the atmosphere. Therefore, in order to supplement the oxygen, the discharge flow rate of the oxygen concentrator 12 is adjusted to about 25 L/min.

If the discharge flow rate of the oxygen concentrator 12 is larger than about 25 L/min, the life of the zeolite built in the oxygen concentrator 12 may be reduced, so the upper limit of the discharge flow rate of the oxygen concentrator 12 is 25L/min is better.

In addition, the oxygen concentrator 12 is an embodiment of the [oxygen concentrator] of the present invention.

The oxygen supply flowmeter 14 is a device that adjusts the flow rate of the concentrated oxygen supplied from the oxygen concentrator 12. For the oxygen supply flowmeter 14, for example, a float type (float type) with a maximum scale of 10 to 12 L/min is used. The oxygen concentrator 12 is driven before the power supply of the booster compressor (supercharger) 18 is turned on, and the oxygen supply flowmeter 14 is set so that the oxygen concentrator 12 is supplied to the booster compressor (supercharger) 18 The flow rate of the concentrated oxygen gas is, for example, 8 L/min.

Here, if the flow rate of the concentrated oxygen supplied from the oxygen concentrator 12 to the supercharger compressor (supercharger) 18 is greater than, for example, 8 L/min, there is a pump of the supercharger compressor (supercharger) 18 (pump) (not shown) The risk of stall. In other words, since a large pressure acts on the pump of the supercharger compressor (supercharger) 18, there is a possibility that the supercharger compressor (supercharger) 18 will not function normally. Therefore, the oxygen supply flowmeter 14 is set so that, for example, the flow rate of concentrated oxygen is in the range of 4 to 8 L/min (more preferably, 8 L/min), and is controlled so that the oxygen concentrator 12 is supplied to the compressor for boosting The flow rate of the concentrated oxygen in the (supercharger) 18 is, for example, in the range of 4 to 8 L/min (more preferably, 8 L/min).

In addition, the oxygen supply flowmeter 14 is an embodiment of the [flow rate adjustment unit] of the present invention.

The purge flowmeter 16 is a device that adjusts the flow rate of the concentrated oxygen blown into the atmosphere. For the purge flowmeter 16, for example, a float type is used, and the maximum scale is 30 L/min. The purge flow meter 16 is provided for the purpose of stably supplying the concentrated oxygen while maintaining the pressure of the concentrated oxygen at 0.4 MPa of the specification value (ISO standard) of the respirator 40 when supplying the concentrated oxygen to the respirator 40 The device can only be used with the anesthesia device 42 used together with the artificial respirator 40. However, in the case of using the anesthesia device 42, the flow rate of the concentrated oxygen discharged into the atmosphere can be controlled by using the purge flow meter 16 to adjust the oxygen concentration during anesthesia.

The purge flowmeter 16 is an embodiment of the [atmospheric release part] of the present invention.

The pressure-increasing compressor (supercharger) 18 is a device for increasing the pressure of the concentrated oxygen supplied from the oxygen concentrator 12 to the artificial respirator 40. For example, when the pressure of the concentrated oxygen supplied from the oxygen concentrator 12 is 0.13 MPa, if the pressure of the ISO standard used as the artificial respirator 40 is, for example, 0.4 MPa, the pressure of the concentrated oxygen becomes about 0.4 MPa, and The appropriate pressure of concentrated oxygen is supplied to the artificial respirator 40.

Specifically, the pressure-increasing compressor (supercharger) 18 pressurizes the concentrated oxygen supplied from the oxygen concentrator 12 to 0.4 MPa or more, for example, 0.5 to 0.6 MPa, and the pressurized concentrated oxygen is stored in the concentrate Oxygen tank 24.

In addition, as the booster compressor (supercharger) 18, for example, manufactured by Sanjinhai: MP-20-2S-TL, power supply AC100V, consumption current (consumption current): 2.25A/50Hz, maximum pressure: 0.8MPa, Discharge flow rate: 20 L/min of products.

The compressor (supercharger) 18 for boosting uses an oilless compressor, and boosts the concentrated oxygen supplied from the oxygen concentrator 12 to about 0.5 to 0.6 MPa. The concentrated oxygen pressurized to about 0.5 to 0.6 MPa is stored in the concentrated oxygen tank 24. Further, the concentrated oxygen pressurized in the range of 0.5 to 0.6 MPa is regulated by the pressure regulator 32 to about 0.4 MPa that meets the specifications of the respirator 40, and then supplied to the respirator 40.

The supercharger compressor (supercharger) 18 is an embodiment of the [supercharger] of the present invention.

The bidirectional valve 20 for residual pressure release is an electromagnetic valve. When the power supply of the booster compressor (supercharger) 18 is OFF (when the drive is stopped), the release valve (not shown) of the residual pressure release bidirectional valve 20 is opened, and the concentrated oxygen in the upstream air flow path 11 Was discharged into the atmosphere. In addition, when the power supply of the booster compressor (supercharger) 18 is ON (during driving), the release valve of the residual pressure release bidirectional valve 20 is closed.

If the drive of the concentrated oxygen booster 10 is stopped for some reason, the output side of the booster compressor (supercharger) 18 will pass through the concentrated oxygen tank 24 during restart The high pressure (for example, 0.5 MPa) is locked, so that a problem arises that the booster compressor (supercharger) 18 cannot be started. In order to prevent this problem, when the driving of the supercharger compressor (supercharger) 18 is stopped, the bidirectional release of residual pressure connected to the output side of the supercharger compressor (supercharger) 18 is attempted. The release valve of the valve 20 is opened to discharge the concentrated oxygen in the upstream air flow path 11 to the atmosphere so that the negative pressure does not act on the output side of the booster compressor (supercharger) 18.

The check valve 22 is provided to prevent the high-pressure (for example, 0.5 MPa) concentrated oxygen stored in the concentrated oxygen tank 24 from flowing back toward the compressor (supercharger) 18 for boosting.

When the release valve of the residual pressure release bidirectional valve 20 is opened, if the check valve 22 is not provided, the concentrated oxygen in the upstream air flow path 11 and the concentrated oxygen tank 24 is also released into the atmosphere at the same time. During the re-operation of the pressure device 10, it is necessary to set a standby time for filling the concentrated oxygen tank 24 with concentrated oxygen. Therefore, by providing a check valve 22 near the inlet side of the concentrated oxygen tank 24, the concentrated oxygen in the concentrated oxygen tank 24 will not escape to the outside together with the concentrated oxygen in the upstream air flow path 11.

The concentrated oxygen tank 24 is a device that stores concentrated oxygen pressurized by a pressurizing compressor (supercharger) 18 to a predetermined pressure (for example, about 0.5 to 0.6 MPa). The oxygen-enriched gas tank 24 is made of, for example, aluminum, and two are used.

Connected to the oxygen enriched tank 24 are a check valve 22, a pressure gauge 26 in the tank, a pressure sensor 28, an exhaust valve 30, and a pressure regulator 32.

In addition, the concentrated oxygen tank 24 is an embodiment of the [storage unit] of the present invention.

The pressure gauge 26 in the tank measures and displays the pressure of the concentrated oxygen in the concentrated oxygen tank 24. The pressure gauge 26 in the tank uses, for example, a Bourdon tube analog manometer with a maximum scale of 0.6 MPa.

The pressure sensor 28 detects the pressure of the concentrated oxygen in the concentrated oxygen tank 24. Specifically, the pressure sensor 28 detects when the pressure of the concentrated oxygen in the concentrated oxygen tank 24 reaches about 0.5 to 0.6 MPa.

The exhaust valve 30 is the same as the two-way valve 20 for residual pressure release. The exhaust valve 30 is opened and closed by a signal from the pressure sensor 28. In other words, as soon as the pressure of the concentrated oxygen in the concentrated oxygen tank 24 reaches about 0.5 to 0.6 MPa, the exhaust valve 30 is opened by the signal from the pressure sensor 28 to release the oxygen in the concentrated oxygen tank 24 Into the atmosphere. On the other hand, as soon as the pressure of the concentrated oxygen in the concentrated oxygen tank 24 drops to about 0.5 MPa, the exhaust valve 30 is closed, so that the pressure of the concentrated oxygen in the concentrated oxygen tank 24 rises again.

Here, without using the exhaust valve 30, the pressure in the concentrated oxygen tank 24 can be controlled by the ON/OFF switching operation of the booster compressor (supercharger) 18, but only the booster compressor (increased (Press) 18 ON/OFF switching sound, the problem of adverse effects on the surrounding relations. Therefore, the following configuration is made: By arranging the exhaust valve 30 intentionally, the supercharger compressor (supercharger) 18 is continuously operated without the aforementioned switching operation.

The pressure regulator 32 is a device that reduces the pressure of the concentrated oxygen in the concentrated oxygen tank 24 to a high pressure of, for example, about 0.5 to 0.6 MPa, so as to optimize the driving of the respirator 40, for example, about 0.4 MPa. . According to this, concentrated oxygen gas having a pressure of, for example, about 0.4 MPa can be supplied to the artificial respirator 40.

The output pressure gauge 34 measures and displays the pressure of the concentrated oxygen supplied to the artificial respirator 40 and the anesthesia apparatus 42. For the output pressure gauge 34, for example, a Burton tube type analog pressure gauge with a maximum scale of 1.0 MPa is used.

For example, when the pressure of the concentrated oxygen supplied to the artificial respirator 40 becomes 0.35 MPa or less, it will be notified by an alarm, but by providing an output pressure gauge 34, the supply to the artificial respirator 40 and/or the anesthesia device 42 can be visually recognized Concentration of oxygen. According to this, it is possible to give peace of mind to the people around you.

A respirator 40 is connected to the respirator connection 36.

An anesthesia device 42 is connected to the anesthesia device connection portion 38.

Next, the operation of the concentrated oxygen pressurization device and the concentrated oxygen pressurization method according to an embodiment of the present invention will be described.

[Simultaneous use of artificial respirators and anesthesia] A description will be given of the simultaneous use of both the artificial respirator 40 and the anesthesia device 42.

As shown in FIG. 1, the oxygen concentrator 12 generates and supplies concentrated oxygen at a predetermined concentration. At this time, the flow rate of the concentrated oxygen supplied from the oxygen concentrator 12 is set to, for example, 25 L/min. The pressure of the concentrated oxygen supplied from the oxygen concentrator 12 is, for example, about 0.13 MPa.

In addition, the flow rate of the concentrated oxygen supplied from the oxygen concentrator 12 is set to 25 L/min because concentrated oxygen equivalent to 20 L/min can be purged, and the lifespan of the zeolite built in the oxygen concentrator 12 can be suppressed from decreasing.

A part of the concentrated oxygen is supplied to the oxygen supply flow meter 14. The flow rate of the concentrated oxygen in the oxygen supply flowmeter 14 is adjusted to a predetermined flow rate. Specifically, the flow rate of the concentrated oxygen in the oxygen supply flowmeter 14 is adjusted to, for example, about 8 L/min.

In addition, the flow rate of the concentrated oxygen is adjusted to, for example, about 8 L/min by the oxygen supply flowmeter 14 because if the flow rate of the concentrated oxygen becomes a value larger than about 8 L/min, it acts on the compressor for boosting (boosting) The pressure of 18) is too high, and the stall function may be reduced.

Concentrated oxygen whose flow rate is adjusted in the oxygen supply flowmeter 14 is supplied to a compressor (supercharger) 18 for boosting. The pressure of the concentrated oxygen in the pressure-increasing compressor (supercharger) 18 is increased. Specifically, the pressure of the concentrated oxygen in the pressure-increasing compressor (supercharger) 18 is increased to, for example, 0.4 MPa or more, and more preferably 0.5 to 0.6 MPa. According to this, when the concentrated oxygen is supplied to the artificial respirator 40 downstream, the artificial respirator 40 operates normally.

Concentrated oxygen pressurized by the booster compressor (supercharger) 18 to, for example, 0.4 MPa or more, more preferably 0.5 to 0.6 MPa is stored in the concentrated oxygen tank 24.

Here, during the driving of the booster compressor (supercharger) 18, the release valve of the residual pressure release bidirectional valve 20 is closed, but when the drive of the booster compressor (supercharger) 18 stops, the residual valve The release valve of the pressure release bidirectional valve 20 is opened, and the concentrated oxygen is discharged into the atmosphere. According to this, the negative pressure does not act on the output side of the supercharger compressor (supercharger) 18 and does not cause an obstacle when the supercharger compressor (supercharger) 18 is re-driven.

In addition, if the release valve of the residual pressure release bidirectional valve 20 is opened, the concentrated oxygen in the concentrated oxygen tank 24 is discharged from the concentrated oxygen tank 24. It takes a lot of time to fill the concentrated oxygen tank 24 with concentrated oxygen. To prevent such concentrated oxygen from escaping, a check valve 22 is provided. According to this, the generation of dead time can be suppressed.

The concentrated oxygen inside the concentrated oxygen tank 24 is supplied to the pressure regulator 32. Accordingly, the pressure of the concentrated oxygen is adjusted by the pressure regulator 32. Specifically, the pressure of the concentrated oxygen inside the concentrated oxygen tank 24 is in the range of 0.5 to 0.6 MPa, which is adjusted slightly higher than the normal pressure required by the artificial respirator 40, so the pressure of the concentrated oxygen is adjusted by the pressure regulator 32 The adjustment is about 0.4 MPa.

The concentrated oxygen whose pressure is adjusted to about 0.4 MPa is supplied to the artificial respirator 40. Here, if the pressure of oxygen concentration in the respirator 40 is about 0.4 MPa, the normal operation is performed. As a result, the therapeutic effect of using the artificial respirator 40 for humans or animals can be improved.

At the same time, the concentrated oxygen is supplied not only to the artificial respirator 40 but also to the anesthesia device 42. As a result, the anesthesia effect using the anesthesia device 42 for humans or animals can be improved.

Here, since a part of the concentrated oxygen is blown (discharged) into the atmosphere by the purge flowmeter 16, the oxygen concentration of the concentrated oxygen supplied to the artificial respirator 40 and the anesthesia device 42 is reduced. According to this, it is possible to suppress the adverse effect of the effect on the living body caused by the excessively high oxygen concentration of the concentrated oxygen supplied to the anesthesia device 42 as a cause.

In addition, as soon as the pressure of the concentrated oxygen in the concentrated oxygen tank 24 reaches about 0.5 to 0.6 MPa, the exhaust valve 30 is opened according to the signal from the pressure sensor 28 and the oxygen in the concentrated oxygen tank 24 is released into the atmosphere. As soon as the pressure of the concentrated oxygen in the concentrated oxygen tank 24 drops to about 0.5 MPa, the exhaust valve 30 closes, and the pressure of the concentrated oxygen in the concentrated oxygen tank 24 rises again. Accordingly, the pressure of the concentrated oxygen in the concentrated oxygen tank 24 is adjusted.

Although the above effects have been described in the case where the artificial respirator 40 and the anesthesia device 42 are used at the same time, only one of the artificial respirator 40 or the anesthesia device 42 may be used in accordance with the application, and the same situation can be obtained in this case. The role.

According to the present embodiment, in recent medical fields, there is an increasing demand for medical devices that integrate anesthesia devices in addition to artificial respirators. According to the present invention, the artificial respirators 40 and the anesthesia devices 42 can be used at the same time.

In particular, by using the oxygen supply source of the oxygen concentrator 12, it can be used for both the artificial respirator 40 and the anesthesia device 42, so it is reasonable.

Here, when the oxygen concentrator 12 is used as an oxygen supply source, if the pressure of the concentrated oxygen supplied to the respirator 40 is insufficient, the pressure of the concentrated oxygen required for normal operation of the respirator 40 cannot be obtained. There is a problem, but since the pressure of the concentrated oxygen can be increased by providing a compressor (supercharger) 18 for boosting, the pressure of the concentrated oxygen required for the normal operation of the artificial respirator 40 can be obtained. According to this, the medical behavior can be performed smoothly, and the quality of the medical behavior can be improved and stabilized.

Furthermore, since a part of the concentrated oxygen supplied from the oxygen concentrator 12 is blown into the atmosphere, it is possible to supply the concentrated oxygen with a reduced oxygen concentration to the anesthesia device 42 at the same time as the artificial respirator 40, making it possible to manage anesthesia appropriately.

In addition, the present invention is not limited to the structure described in the above embodiment. Within the scope of the present invention, all aspects using the technical idea of the present invention are included.
