(First embodiment)
A concentrated oxygen generator 1A according to the first embodiment will be described with reference to FIGS.

[Constitution]
1-1. overall structure
The overall configuration of the concentrated oxygen generator 1A according to the first embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing an example of the configuration of a concentrated oxygen generator 1A according to the first embodiment.

  As shown in FIG. 1, the concentrated oxygen generator 1A according to the first embodiment includes a compressor 11, a cooler 12, a drain separator 13, adsorption cylinders 14A and 14B, a buffer tank 15, electromagnetic valves 16a to 16g, a filter 151, a touch panel. 18, the switch 19, the memory 20, the battery 22, the ejection part 130, and the controller 17 for controlling the said structure.

  The compressor 11 sucks external air into the compressor 11 and discharges compressed air compressed by applying a predetermined pressure to the sucked air. Here, the temperature of the compressed air compressed by the compressor 11 is increased by pressurization. Therefore, the pipe 10 that connects the compressor 11 and the cooler 12 may be a metal pipe that has an excellent heat dissipation effect, such as a copper or aluminum pipe.

  The cooler 12 cools the compressed air whose temperature has risen in order to prevent functional deterioration of the adsorbents 141A and 141B described later. For example, the cooler 12 cools the compressed air whose temperature has risen to about room temperature.

  The drain separator 13 separates steam and dust in the compressed air cooled by the cooler 12 and eliminates them. This is because these vapors in the compressed air are unnecessary components for producing concentrated oxygen.

  The adsorption cylinders (generation units) 14A and 14B include adsorbents 141A and 141B, respectively. One of the adsorption cylinders 14A and 14B adsorbs nitrogen in the compressed air discharged from the drain separator 13 by one of the adsorbents 141A and 141B to generate concentrated oxygen gas having a higher oxygen concentration than the air (adsorption process). The other of the adsorption cylinders 14A and 14B discharges the nitrogen adsorbed on the other of the adsorbents 141A and 141B to the outside, and regenerates the other adsorption effect of the adsorbents 141A and 141B (desorption process). The adsorption cylinders 14A and 14B perform these two adsorption processes and desorption processes at the same time by controlling the opening and closing of the electromagnetic valves 16a to 16f in accordance with the control signals CSa to CSf. Further, the adsorption process and the desorption process are alternately repeated between the adsorption cylinders 14A and 14B. Details of this operation will be described later.

  The adsorbents 141A and 141B have a large number of pores, and nitrogen is selectively taken into the numerous pores to increase the oxygen concentration in the compressed air. As the adsorbents 141A and 141B, for example, zeolite that is a crystalline hydrous aluminum silicate containing an alkaline earth metal is used. Zeolite has the property of adsorbing nitrogen more than oxygen. Utilizing such properties of the adsorbents 141A and 141B, a concentrated oxygen gas having a higher oxygen concentration than the air is generated from the compressed air, and for example, an oxygen gas having a high oxygen concentration in a range of 90% to 96% is generated. Let Furthermore, in this embodiment, the temperature of the compressed air is cooled by the cooler 12, and unnecessary components such as vapor of the compressed air are removed by the drain separator 13. Therefore, it is possible to prevent the performance of the adsorbents 141 </ b> A and 141 </ b> B from being deteriorated and to generate a high concentration and high quality oxygen gas.

  The buffer tank (pressure adjusting unit) 15 temporarily stores the oxygen gas generated from the adsorption cylinders 14A and 14B, and adjusts the pressure of the oxygen gas to be a predetermined pressure. The buffer tank 15 is preferably made of a metal material having a high hardness suitable for periodic changes in oxygen gas, which will be described later, and a material having a larger volume.

  The filter 151 sterilizes bacteria in the oxygen gas ejected to the outside, and removes dust and the like in the oxygen gas. The oxygen gas that has been sterilized by the filter 151 passes through the tube 120 attached by the predetermined attachment adapters 100a and 100b via the connection port 111 and is ejected from the ejection port 140 of the ejection part 130. Is done.

  The touch panel (display unit and input unit) 18 displays at least the oxygen gas application 18a and the oxygen gas ejection frequency 18b. An external user can arbitrarily select an oxygen gas application 18 a and an oxygen gas ejection frequency 18 b displayed on the touch panel 18. Therefore, the touch panel 18 also functions as an input unit for transmitting an input from an external user to the controller 17. For example, when the user selects a certain application 18a displayed on the touch panel 18, a plurality of oxygen gas ejection frequencies 18b suitable for the application 18a are displayed. When the user selects one of the plurality of oxygen gas ejection frequencies 18b, the application and the ejection frequency are determined. The items displayed on the touch panel 18 are not limited to these, and as will be described later, for example, the concentration of oxygen gas, the flow rate (volume), the pressure (may be the jetting intensity or the speed), the remaining amount of the battery 22, and the like. May be.

  The switch 19 is a switch for operation that is physically provided, such as an operation switch for the user to select increase / decrease in the oxygen gas ejection frequency and a power switch for switching on / off the power source. is there.

  The memory 20 includes a ROM (Read Only Memory) 20a and a RAM (Random Access Memory) 20b, and stores various programs and data. In the present embodiment, the ROM 20b stores a table T1 indicating the relationship between the use of oxygen gas and the ejection frequency. The ROM 20a is a nonvolatile memory or the like that can store stored data even when the power supply from the battery 22 is cut off, and is configured by, for example, an HDD (Hard Disc Drive) or an SSD (Solid State Drive). . The RAM 20b is a volatile memory or the like in which stored data is lost when the power supply from the battery 22 is cut off. The RAM 20b includes, for example, an SRAM (Static Random Access Memory) or a DRAM (Dynamic Random Access Memory). The On the RAM 20b, calculation results, data, and the like are expanded as necessary.

  The battery 22 is charged by receiving power from the external power supply 25 via the power connectors 23a and 23b, and supplies necessary power to each of the above components under the control of the controller 17. The external power supply 25 is, for example, a commercial AC power supply of 100 [V]. The power connectors 23a and 23b are configured to be detachable from the external power source 25. Therefore, the concentrated oxygen generator 1 </ b> A can operate with the electric power supplied from the battery 22 even in a situation where electric power cannot be supplied from the external power supply 25. It should be noted that the present invention is not limited to the configuration including the battery 22 and may be configured to operate by receiving power supply directly from the external power supply 25.

  The ejection part 130 is for injecting (or penetrating) the oxygen gas ejected from the ejection port 140 into the inside from the surface of a predetermined body of the affected part. Here, it is comprised so that it can replace | exchange between either the some ejection parts 130a-130c connected via the tube 120. FIG. Specifically, since the structure of the mounting adapter 100b of the plurality of ejection portions 130a to 130c is common, any of the ejection portions 130a to 130c is mutually connected to the mounting adapter 100a provided on the connection port 111 side. It is possible to connect.

  The ejection part 130a is a single injection type probe having a single ejection port 140 that ejects oxygen gas. Since the ejection part 130a has a single ejection outlet 140, it is effective in that oxygen gas can be ejected to delicate parts of the body such as the face, neck, and head, and oxygen can be injected from the ejected part. Moreover, the ejection part 130a is also effective for injecting oxygen into a part where the nerves of the body such as the eyes and mouth are more sensitive.

  The ejection portion 130b is a triple injection probe having three ejection ports 140 that eject oxygen gas. Since the ejection part 130b ejects oxygen gas from the three ejection ports 140 simultaneously, it is effective for injecting oxygen into a wide part of the body such as the foot and the back.

  The ejection portion 130c is a headset probe configured to suck oxygen gas ejected from the ejection port 140 from the nose. The ejection part 130c is effective in injecting oxygen from the inside of the body because it can suck high concentration and high quality oxygen gas directly from the nose.

  In addition, the ejection part 130 is not restricted to what was mentioned above. For example, it may be a face mask type configured to cover the entire face, or a spray type probe that ejects oxygen gas in a spray form. The spray type probe is capable of injecting oxygen into a predetermined body part by ejecting oxygen gas in a spray form together with a predetermined solution such as an aroma solution.

  In addition, as illustrated in FIG. 1 by enlarging the inside of the ejection portion 130a, the piping at the tip is provided with an electromagnetic valve 16g for controlling the ejection frequency of oxygen gas ejected to the outside. As will be described later, the electromagnetic valve 16g periodically changes the oxygen gas ejected from the ejection port 140 by periodically opening and closing its own valve in accordance with a control signal CSg from the controller 17. Similarly, in the other ejection parts 130b and 130c, the solenoid valve 16g is provided in the piping at the tip part inside thereof.

  The controller (control unit) 17 controls each of the above components by the control signal CS, and controls the overall operation of the concentrated oxygen generator 1A. The controller 17 according to the present embodiment includes an electromagnetic valve control unit 171 and a compressor control unit 172. The electromagnetic valve controller 171 controls the opening and closing and the opening degree of the electromagnetic valves 16a to 16g according to the control signals CSa to CSg. The compressor control unit 172 controls the operation of the compressor 11 by a control signal CS11 (not shown). The controller 17 is configured by a processor such as a CPU (Central Processing Unit), for example.

  Moreover, the surrounding member 29 which covers each said structure is provided. The surrounding member 29 is formed of, for example, a predetermined resin having high hardness.

1-2. Table T1
The table T1 will be described in detail with reference to FIG. FIG. 2 is a diagram illustrating an example of the table T1 in FIG.

  As shown in FIG. 2, the table T <b> 1 shows the oxygen gas ejection frequency H and the application that matches the ejection frequency H. Here, the oxygen gas ejection frequency refers to the number of dense waves [Hz] of the oxygen gas ejected repeatedly per unit time [1 second]. For example, applications 1 that match the 0.5 Hz discharge frequency of oxygen gas include asthma, cough, back pain, hyperthyroidism, muscle pain and damage, muscle stiffness, tendon myopathy, toxin removal, and anti-aging , Brachial neuralgia, excretion stimulation, melatonin, and back pain are shown. Similarly, Helicobacter pylori and macular degeneration are shown as application 2 that conforms to an ejection frequency of 0.6 [Hz]. As shown in FIG. 2, the variable range of the oxygen gas ejection frequency is preferably about 0.5 [Hz] to about 3.0 [Hz].

  In addition, it is not limited to the usage 1 to the usage 13 shown in the table T1. For example, the present invention can be applied in a very wide range of other uses and fields such as anti-aging use, sports use, beauty use, esthetic use, therapy use, and medical use caused by lack of oxygen.

[Operation]
The concentrated oxygen generation process of the concentrated oxygen generator 1A having the above configuration will be described with reference to FIG. FIG. 3 is a flowchart showing an example of the concentrated oxygen generation process according to the first embodiment. Here, when the user operates the application 18a and the ejection frequency 18b displayed on the touch panel 18, the ejection frequency of 3.0 [Hz] shown in FIG. A case where “abdominal pain” is selected will be described as an example.

  In step S11, the compressor control unit 172 of the controller 17 transmits a control signal CS11 to the compressor 11, sends air from the outside into the compressor 11, and compresses the sent air to generate predetermined compressed air. The compressor 11 is controlled.

  In step S12, the controller 17 controls the cooler 12 so as to cool the temperature of the compressed air generated by the compressor 11 to, for example, about room temperature.

  In step S13, the controller 17 controls the drain separator 13 so as to remove unnecessary components such as moisture in the compressed air cooled to a predetermined temperature.

In step S14A, the solenoid valve control unit 171 of the controller 17 introduces compressed air into one adsorption cylinder 14A, removes nitrogen or the like in the introduced compressed air with the adsorbent 141A, and concentrates and concentrates oxygen. The electromagnetic valves 16a, 16b, and 16e are controlled so that oxygen is discharged to the buffer tank 15 (adsorption process). For example, as shown in FIG. 4A, the solenoid valve control unit 171 controls the control valves CSa and CSb to open the solenoid valves 16a and 16b provided on the upstream and downstream pipes 10 of the adsorption cylinder 14A. The solenoid valve 16e for connecting to the exhaust port 112 is set to the “closed” state by the signal CSe. By the above control, nitrogen (N ₂ ) indicated by white circles in the compressed air is selectively taken into a large number of pores of the adsorbent 141A to increase the concentration of oxygen (O ₂ ) indicated by black circles in the compressed air. .

In step S14B, at the same time as the adsorption step in step S14A, the electromagnetic valve control unit 171 of the controller 17 reduces the pressure in the other adsorption cylinder 14B to atmospheric pressure, and removes nitrogen and the like adsorbed by the adsorbent 141B. The electromagnetic valves 16c, 16d, and 16f are controlled so as to be discharged to the outside atmosphere and to regenerate the adsorbent 141B (desorption process). For example, as shown in FIG. 4A, the electromagnetic valve control unit 171 sets the electromagnetic valves 16c and 16d provided in the pipes 10 upstream and downstream of the adsorption cylinder 14B to the “closed” state by the control signals CSc and CSd. Then, the solenoid valve 16f for connecting to the exhaust port 112 is opened by the control signal CSf. By the above control, nitrogen (N ₂ ) indicated by white circles adsorbed by a large number of pores of the adsorbent 141B is discharged to the outside from the exhaust port 112, and the adsorbent 141B is regenerated until nitrogen can be adsorbed again.

  Here, the adsorption step and the desorption step are alternately repeated between the adsorption cylinders 14A and 14B at a predetermined time interval such as several tens of seconds. For example, as shown in FIG. 4B, when a predetermined time has elapsed from the state of FIG. 4A, the controller 17 switches the same operation so that the adsorption process is performed by the adsorption cylinder 14B and the desorption process is performed by the adsorption cylinder 14A. Run.

  In step S15, the electromagnetic valve control unit 171 of the controller 17 refers to the table T1 when the oxygen gas is ejected from the ejection port 140 through the connection port 111 connected to the buffer tank 15, and the electromagnetic signal is controlled by the control signal CSg. The opening and closing of the valve 16g is periodically controlled to control the oxygen gas ejection frequency. For example, as shown in FIGS. 4A and 4B, the electromagnetic valve control unit 171 controls the number of opening / closing operations per unit time of the “open” state and the “closed” state of the electromagnetic valve 16g to 3 times (3 [Hz]). . By controlling the period of the electromagnetic valve 16g in this way, the ejection frequency 3 [Hz] set by the user is given to the oxygen gas ejected from the ejection port 140 in accordance with the period of the electromagnetic valve 16g.

  In step S <b> 16, the controller 17 determines whether or not to end the process based on, for example, whether or not a power-off signal is notified by operating the switch 19. For example, when the condition of step S16 is satisfied (eg, a power-off signal is notified) (Yes in S16), the controller 17 ends this process. On the other hand, when the condition of step S16 is not satisfied (No in S16), the controller 17 repeats steps S11 to S15.

[Function and effect]
As described above, the concentrated oxygen generator 1A according to the first embodiment includes the electromagnetic valve (first electromagnetic valve) 16g for giving the ejection frequency to the oxygen gas, and the electromagnetic valve control unit 171 of the controller 17 sets the electromagnetic valve. The opening and closing of 16 g is periodically controlled to control the ejection frequency of oxygen gas ejected from the ejection port 140 (FIGS. 1 and 3). Thus, oxygen gas suitable for various uses can be generated by giving the oxygen gas an ejection frequency suitable for various uses.

  Compared to the first embodiment, for example, in a concentrated oxygen generator that merely ejects oxygen gas at a constant intensity, oxygen generated only in a very limited application and field, such as oxygen gas for oxygen suction, etc. Gas cannot be used, and it is difficult to contribute to the improvement of convenience.

  On the other hand, according to the concentrated oxygen generator 1A according to the first embodiment, an ejection frequency suitable for a wide range of applications can be given to the oxygen gas. For example, as shown on the left side of FIG. 5, according to the concentrated oxygen generator 1 </ b> A according to the first embodiment, in the unit time TU <b> 1, for example, an ejection frequency of 3.0 [Hz suitable for the application 13 including “abdominal pain” and the like. ] Can be given to oxygen gas. Specifically, since the solenoid valve 16g is in the “open” state at times t1 to t2, between times t3 and t4, and between times t5 and t6, for example, about 0.2 [MPa ] High-concentration oxygen gas having a certain intensity (pressure) I1 is ejected. On the other hand, since the solenoid valve 16g is in the “closed” state at times t2 to t3, times t4 to t5, and times t6 to t7, the oxygen gas ejection strength (pressure) is substantially equal. Thus, the pressure becomes 0 atm, and oxygen gas is not substantially ejected to the outside. Further, for example, as shown on the right side of FIG. 5, the ejection frequency is switched in the same manner, and the ejection frequency 1.0 [Hz] suitable for the application 4 including, for example, “muscle pain and injury” in the unit time TU1. Can be easily switched to oxygen gas.

  Moreover, the solenoid valve 16g for controlling the oxygen gas ejection frequency is provided in the vicinity of the ejection port 140 at the tip of the ejection portion 130. Therefore, since the generated ejection frequency can be transmitted to the affected area more reliably without being attenuated, a more reliable effect can be expected.

  Thus, according to the concentrated oxygen generator 1A according to the first embodiment, the oxygen gas is used by intermittently providing the generated oxygen gas with a dense portion and a sparse portion periodically. And can expand the field. For example, the table T1 shown in FIG. 2 includes over 300 very wide uses and fields such as anti-aging use, sports use, beauty use, esthetic use, therapy use, and medical use caused by lack of oxygen. Can be shown. As a result, it is possible to contribute to improving the quality of life of the user, and it is possible to improve convenience.

(Second Embodiment)
Next, the concentrated oxygen generator 1B according to the second embodiment will be described with reference to FIGS. In this description, a detailed description of portions substantially overlapping with the first embodiment is omitted.

[Constitution]
The overall configuration of the concentrated oxygen generator 1B according to the second embodiment will be described with reference to FIG. FIG. 6 is a block diagram showing an example of the concentrated oxygen generator 1B according to the second embodiment. As shown in FIG. 6, the concentrated oxygen generator 1B further includes a safety solenoid valve 16h and a pressure sensor 30 as compared to the concentrated oxygen generator 1A according to the first embodiment.

  The safety solenoid valve (second solenoid valve) 16h is provided between the buffer tank 15 and the pressure release port 113, and its open / close state is controlled in accordance with a control signal CSh from the solenoid valve controller 171 of the controller 17. Here, the safety solenoid valve 16 h is provided between the pipe 10 on the upstream side of the buffer tank 15 and the pressure release port 113.

  The pressure sensor 30 is provided on the upstream side in the buffer tank 15 and detects the pressure in the buffer tank 15. The pressure sensor 30 is not limited to the buffer tank 15 and can be disposed at a predetermined position of the pipe 10.

  Since other configurations are substantially the same as those of the first embodiment, detailed description thereof is omitted.

[Operation]
The concentrated oxygen generation process of the concentrated oxygen generator 1B according to the second embodiment will be described with reference to FIG.

  In steps S11 to S15, the controller 17 performs the same operation as in the first embodiment.

  In step S <b> 21, the controller 17 detects that the pressure detected by the pressure sensor 30 is predetermined in a transition period in which a certain one of the plurality of ejection frequencies (first ejection frequency) is changed to another frequency (second ejection frequency). It is determined whether or not the threshold value is exceeded. For example, in the table T1 shown in FIG. 2, a case where the ejection frequency is switched so as to increase from 0.5 [Hz] to 3.0 [Hz] is taken as an example. In this case, the solenoid valve controller 171 changes the pressure in the buffer tank 15 detected by the pressure sensor 30 during the transition period in which the ejection frequency is changed to increase from 0.5 [Hz] to 3.0 [Hz]. It is determined whether or not a predetermined threshold is exceeded. If the pressure in the buffer tank 15 detected by the pressure sensor 30 is less than the predetermined threshold (No in S21), the controller 17 advances the process to step S16.

  When the pressure in the buffer tank 15 detected by the pressure sensor 30 exceeds a predetermined threshold (Yes in S21), in step S22, the electromagnetic valve control unit 171 of the controller 17 “opens the safety electromagnetic valve 16h by the control signal CSh. In this state, the oxygen gas in the buffer tank 15 is released from the pressure release port 113 to the outside. Thereby, the pressure in the buffer tank 15 is reduced to the external atmospheric pressure. At this time, a safety solenoid valve 16h may be provided in the internal pipe 10 to release the oxygen gas in the buffer tank 15 to the inside of the apparatus 1B.

  Furthermore, although illustration is omitted, when the pressure in the buffer tank 15 detected by the pressure sensor 30 exceeds a predetermined threshold (Yes in S21), the compressor control unit 172 of the controller 17 receives the control signal CS11 following step S22. May be transmitted to temporarily stop or reduce the operation of the compressor 11.

  Since other operations are substantially the same as those in the first embodiment, detailed description thereof is omitted.

[Function and effect]
According to the configuration and operation of the concentrated oxygen generator 1B according to the second embodiment, the same effect as in the first embodiment can be obtained.

  Furthermore, the concentrated oxygen generator 1B according to the second embodiment includes a safety electromagnetic valve 16h provided in the buffer tank 15 and a pressure sensor 30 that detects the pressure in the buffer tank 15 (FIG. 6). The solenoid valve control unit 171 detects the pressure sensor 30 in a transition period (for example, from 0.5 [Hz] to 3.0 [Hz]) in which a certain first ejection frequency is changed to another different second ejection frequency. When it is determined that the pressure exceeds a predetermined threshold value, the safety solenoid valve 16h is opened, and the oxygen gas in the buffer tank 15 is released to the outside from the pressure release port 113 (S21 and S22 in FIG. 7). Thereby, the pressure in the buffer tank 15 is reduced to the external atmospheric pressure.

  Therefore, for example, the buffer tank 15 and the piping 10 are prevented from being damaged in the transition period of the change of the ejection frequency that is changed so that the ejection frequency increases from 0.5 [Hz] to 3.0 [Hz]. can do. As a result, it is advantageous in that the reliability can be further improved.

  In addition, when the pressure in the buffer tank 15 detected by the pressure sensor 30 exceeds a predetermined threshold (Yes in S21), the compressor control unit 172 of the controller 17 temporarily stops the operation of the compressor 11 or continues to step S22. Reduce. As a result, it is possible to prevent the buffer tank 15 and the pipe 10 from being damaged, and to eliminate wasteful operation of the compressor 15 and reduce power consumption.

  In addition, although the transitional period of the change in which an ejection frequency increases was mentioned as an example here, it is not limited to this. Needless to say, similar effects can be obtained even in a transition period in which the ejection frequency is changed to decrease, for example, from 3.0 [Hz] to 0.5 [Hz].

(Third embodiment)
Next, a concentrated oxygen generator 1C according to the third embodiment will be described with reference to FIGS. In this description, a detailed description of portions substantially overlapping with the first embodiment is omitted.

[Constitution]
The overall configuration of the concentrated oxygen generator 1C according to the third embodiment will be described with reference to FIG. FIG. 8 is a block diagram illustrating an example of the concentrated oxygen generator 1C according to the third embodiment. As shown in FIG. 8, the concentrated oxygen generator 1C is stored in a plurality of pipes 10a to 10c, a plurality of solenoid valves 16ia to 16ic, and a ROM 20a, compared to the concentrated oxygen generator 1A according to the first embodiment. The table T2 is further provided, and the ejection strength (pressure) 18c and the ejection amount 18d are displayed on the touch panel 18 so as to be further operable.

  The plurality of pipes 10a to 10c are configured so as to connect the downstream side of the buffer tank 15 and the filter 151, and the diameters thereof are sequentially increased.

  The plurality of solenoid valves 16ia to 16ic are provided in the plurality of pipes 10a to 10c, respectively. The controller 17 selects one of the solenoid valves 16ia to 16ic (“open” state) and makes the other non-selected (“closed” state) by the control signal CS16i. Here, the case where the electromagnetic valve 16ib is selected (“open” state) and the oxygen gas path is the pipe 10b is illustrated. In this way, the oxygen gas ejection intensity (pressure) is controlled by controlling the path through which the oxygen gas passes.

  As shown in FIG. 9, the table T <b> 2 shows a plurality of usages, and a plurality of oxygen gas ejection strengths (pressures), ejection amounts, and ejection part recognition information corresponding to the plurality of usages in association with each other. . For example, the use 1 and the ejection frequency 101H (0.5 [Hz]), the ejection intensity 101I, the ejection amount 101V, and the recognition information of the ejection part 130b are shown in association with each other.

  On the touch panel 18, for example, the oxygen gas ejection intensity 18 c and the ejection amount 18 d currently being executed shown in the table T 2 are further displayed. Thereby, the user can further select these by operating the ejection intensity 18c and the ejection amount 18d of the oxygen gas displayed on the touch panel 18.

  Since other configurations are substantially the same as those of the first embodiment, detailed description thereof is omitted.

[Operation]
The concentrated oxygen generation process of the concentrated oxygen generator 1C according to the third embodiment is different from the first embodiment in the following points. In this description, reference to the drawings is omitted.

  In step S15, the electromagnetic valve control unit 171 of the controller 17 refers to the table T2 when oxygen gas is ejected from the ejection unit 130 to the outside, and controls the opening and closing and the opening degree of the electromagnetic valve 16g by the control signal CSg. The ejection frequency H and the ejection amount (flow rate) V of the oxygen gas to be ejected are controlled. For example, the solenoid valve controller 171 periodically controls the opening and closing and the opening degree of the solenoid valve 16g to control the oxygen gas ejection amount (flow rate) V in a range of about 0 to 6 [L / min]. Is possible.

  Furthermore, in the same step S15, the solenoid valve control unit 171 of the controller 17 controls the solenoid valves 16ia to 16ic by the control signal CS16i, and selects any of the pipes 10a to 10c that are paths through which oxygen gas passes. Thus, the strength (pressure) I of the oxygen gas to be ejected is controlled.

  Since other operations are substantially the same as those in the first embodiment, detailed description thereof is omitted.

[Function and effect]
According to the configuration and operation of the concentrated oxygen generator 1C according to the third embodiment, the same effect as in the first embodiment can be obtained.

  Furthermore, the concentrated oxygen generator 1C according to the third embodiment further includes a table T2 stored in the ROM 20a, and is displayed on the touch panel 18 so that the ejection intensity 18c and the ejection amount 18d can be further operated (FIG. 8, FIG. 9).

  In the above configuration, when the controller 17 ejects oxygen gas from the ejection port 140, the controller 17 refers to the table T2, controls the periodic opening and closing and the opening degree of the electromagnetic valve 16g, and ejects the oxygen gas to the ejection frequency H. And the ejection amount (flow rate) V, and further, the solenoid valves 16ia to 16ic are controlled by the control signal CS16i to select any one of the pipes 10a to 10c through which the oxygen gas passes. The strength (pressure) I of the is controlled.

  Therefore, not only the ejection frequency H given to the ejected oxygen gas can be arbitrarily controlled, but also the strength (pressure) I and the ejection amount V of the ejected oxygen gas can be arbitrarily controlled, thereby further improving convenience. be able to.

  For example, as shown in FIG. 10, by switching the path through which oxygen gas passes to a pipe 10c having a larger diameter than that of the pipe 10b, an ejection frequency of 3.0 [Hz] suitable for the application 13 is given to the oxygen gas. In addition, it is possible to generate oxygen gas having an ejection intensity I0 of about 0.1 [MPa] reduced from the ejection intensity I1 of about 0.2 [MPa] to about half.

  Furthermore, as shown in FIG. 11, by switching the path through which oxygen gas passes to pipe 10a having a smaller diameter than pipe 10b, an ejection frequency of 2.0 [Hz] suitable for application 10 is given to oxygen gas. In addition, it is possible to generate oxygen gas having an ejection intensity I2 that is greater than the ejection intensity I1 and an ejection amount V2 that is greater than the ejection amount V0.

(Fourth embodiment)
Next, a concentrated oxygen generator 1D according to the fourth embodiment will be described with reference to FIGS. In this description, a detailed description of portions substantially overlapping with the first embodiment is omitted.

[Constitution]
The overall configuration of the concentrated oxygen generator 1D according to the fourth embodiment will be described with reference to FIG.

  As shown in FIG. 12, the concentrated oxygen generator 1 </ b> D is configured so that the ejection unit 130 can be used by a plurality of people. Specifically, the tube 120 is shared, and a plurality of ejection portions 130A to 130C each including a plurality of ejection portions 130a to 130c are connected.

  In the table T2 of FIG. 12, similarly to FIG. 9, a plurality of uses and a plurality of ejection frequencies, ejection intensities, ejection amounts, ejection portions 130, and the number of people using the apparatus 1D are shown in association with each other. Moreover, on the touch panel 18, the ejection part 18e and the number 18g of persons are displayed so that selection is possible corresponding to the ejection parts 130a-130n.

[Operation]
The concentrated oxygen generation process of the concentrated oxygen generator 1D according to the fourth embodiment will be described with reference to FIG. The concentrated oxygen generation process is different from the first embodiment in the following points.

  In Step S31, following Steps S14A and S14B, the controller 17 refers to the table T2 and displays an instruction to mount the ejection unit 130 suitable for the designated use on the touch panel 18. For example, as illustrated in FIG. 14, when the user selects “abdominal pain” in the usage 13, the selected “abdominal pain” is displayed in the usage 18 a of the touch panel 18. In this case, the controller 17 refers to the table T2, and the ejection frequency 3.0 [Hz], the ejection intensity 2.0 [MPa], and the ejection amount 5.0 [L / L] that match the selected “abdominal pain”. min] is selected, and the selected item is displayed on the display unit 18. In addition, the controller 17 indicates “please wear” as an instruction to wear the triple injection type probe 18e, which is a jet part 130b suitable for “abdominal pain” in the use 13 designated on the touch panel 18. Is displayed on the touch panel 18.

  In step S32, the controller 17 displays the number of persons applicable to the ejection part 130 selected in step S31.

  In step S33, when the controller 17 ejects oxygen gas from the ejection unit 130 to the outside in accordance with the selected ejection unit 130 and the number of people that can be used, the oxygen gas ejection frequency H, ejection intensity I, ejection amount V is similarly controlled.

[Function and effect]
According to the configuration and operation of the concentrated oxygen generator 1D according to the fourth embodiment, the same effects as those of the first to third embodiments can be obtained.

  Furthermore, the controller 17 of the concentrated oxygen generator 1D according to the fourth embodiment refers to the table T2, and includes the ejection frequency, the ejection strength, and the ejection amount of the oxygen gas that is injected from the ejection portion 130 into the predetermined part of the body. Control is performed by switching at least one (FIGS. 12 and 13). Thereby, the optimal oxygen gas ejection frequency H, ejection intensity I, and ejection amount V according to the ejection part 130 can be selected. Therefore, a higher oxygen gas injection effect can be expected.

  In addition, the controller 17 displays on the touch panel 18 a message 18f “please attach” as an instruction to attach the ejection part 130 suitable for the designated use on the touch panel 18 (FIG. 14). . Thereby, the ejection part 130 suitable for the user's application is correctly selected, and the ejection frequency, ejection intensity, ejection amount, and ejection part 130 suitable for the application are selected to maximize the oxygen gas injection effect. Is possible.

  Moreover, the controller 17 similarly controls the oxygen gas ejection frequency H, the ejection intensity I, and the ejection amount V in accordance with the selected usable number of persons when the oxygen gas is ejected from the ejection section 130 to the outside. . Therefore, even if there are a plurality of persons, the oxygen gas ejection frequency H, the ejection intensity I, and the ejection amount V can be controlled to desired values, and the plurality of persons can simultaneously use the concentrated oxygen generator 1D. Therefore, convenience can be further improved.

When sufficient high-concentration oxygen is accumulated in the buffer tank 15, a configuration including a single adsorption cylinder 141 may be used.

  In addition, the configuration for controlling the oxygen gas ejection strength (which may be pressure or velocity) is not limited to the configuration shown in the present embodiment. For example, the compressor control unit 172 of the controller 17 may transmit the control signal CS11 to the compressor 11, control the pressure driving of the compressor 11, and control the oxygen gas ejection intensity.

  Furthermore, the concentrated oxygen generators 1 </ b> A to 1 </ b> D can be applied as medical instruments as necessary. Of course, the present invention can be similarly applied to configurations and operations combined with the contents disclosed in the above embodiments.
