  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows an oxygen enricher according to Embodiment 1 of the present invention.

  As shown in the figure, the oxygen enricher according to the present embodiment includes an oxygen enriched film 2 that converts oxygen enriched air 2 when the atmosphere passes through the oxygen enricher main body 1, and the oxygen enriched device. A suction pump 3 that sucks air through the membrane 2, a silencer (silencer) 4 that reduces pulsation and noise of the air discharged from the suction pump 3, and oxygen-enriched air from the suction pump 3 The discharge part 5 for discharging to the respiratory organs is provided, and these are communicated by a pipe 6.

  Further, the oxygen enricher main body 1 has a control circuit 7 for controlling the operation of the suction pump 3 by increasing / decreasing the energization amount of the suction pump 3, the operation switch 8 of the oxygen enricher main body 1, and an energization display by lighting. An energizing lamp 9 that generates a timing signal for a predetermined time to set the operating time of the suction pump 3, and the oxygen-enriched film 2 by sucking the atmosphere through an intake hole 12 provided in the oxygen enricher main body 1. The water tank 13 is detachably provided in the middle of the pipe 6 which is a flow path for supplying oxygen-enriched air to the respiratory organs of the user. However, the fan 11 is for ensuring the amount of air passing through the oxygen-enriched film 2, and it is possible to ensure the amount of air by increasing the area of the oxygen-enriched film 2, and this is always necessary. is not. Further, the control wiring that connects the suction pump 3, the energizing lamp 9, and the fan 11 and the control circuit 7 controlled by the output signal of the control circuit 7 is not shown in FIG.

  Here, when the power cord is connected to the power source and the operation switch 8 is operated, the suction pump 3 attached via the vibration isolating material operates. The suction pump 3 is controlled by the control circuit 7 and is operated for a time set by the timer 10 while the energizing lamp 9 is turned on. The air is sucked from the intake hole 12 provided in the oxygen enricher main body 1 by the action of the fan 11, passes through the oxygen enriched film 2, and is discharged from the discharge unit 5 as oxygen enriched air. The suction pump 3 is preferably a bellows pump having a high pressure during operation, and can increase the air flow rate against the passage pressure loss of the oxygen-enriched membrane 2. The silencer 4 can effectively act and suppress the pulsation and vibration sound of the air being conveyed.

  The oxygen-enriched membrane 2 has a higher oxygen permeation rate than a nitrogen permeation rate, and more particularly twice or more faster in the present embodiment. It can be generated.

  In addition, the oxygen-enriched membrane 2 has a water vapor permeability higher than that of nitrogen and has a higher humidity of air enriched in the oxygen-enriched membrane 2 when operated in an atmosphere having a high humidity. 13 is separated and removed. This prevents water droplets from being scattered from the discharge portion 5 to the user's mouth and giving discomfort.

  In this way, the oxygen concentration in the atmosphere is enriched from 20.9% to 28-30% and delivered to the user's respiratory organ (mouth or nostril). This oxygen-enriched air is sent from the discharge unit 5 to the user. As shown in FIG. 2, when the flow rate of the suction pump 3 is constant, the discharge unit 5 is connected to the user by a headphone-type fixture 14. The distance is maintained, and when breathing, the concentration of oxygen to be sucked is adjusted to be 22 to 25%. Physiological and psychological effects can be obtained when the user sucks the oxygen-enriched air.

  FIG. 3 shows the relationship between the distance from the discharge unit 5 to the respiratory organ (mouth or nostril) and the oxygen concentration. At this time, the oxygen concentration of the air supplied from the discharge unit 5 was 30%, the supply amount of air was 3 L / min, and the discharge port inner diameter of the discharge unit 5 was 3 mm.

  If the discharge part 5 is 50 mm from the mouth or nostril, the oxygen concentration can be maintained at 23% or more. Therefore, in order to supply oxygen-enriched air with an oxygen concentration of 30% at 3 L / min and to make the oxygen concentration of the user's respiratory organs 23%, it is desirable that the air is disposed at least within 50 mm.

  When the user continues to inhale oxygen-enriched air with an oxygen concentration of 30% under these conditions, as shown in FIG. 4, the amount of oxygen taken into the body is linear immediately after the start of inhalation (0 min in the figure). To rise.

  FIG. 5 shows an example of the effect when the oxygen-enriched air whose oxygen concentration is changed is sucked for 30 minutes. When the oxygen suction effect is relatively compared with typical learning-related effects, an improvement effect can be confirmed if the oxygen concentration is slightly higher than that in the atmosphere, which is 23% (average value of suction). At this time, the evaluation standard is represented by a change in the correct answer rate (decrease in the incorrect answer rate) in the first place addition test.

  The memory was also evaluated under the same conditions, and as shown in FIG. 6, the effect could be obtained by sucking oxygen-enriched air having an oxygen concentration of 23%. Therefore, the effect can be obtained if at least the oxygen concentration (average value) is 23%.

  When oxygen-enriched air is aspirated, an effect of activating the human brain, particularly the hippocampus, can be seen even when the oxygen concentration is slightly high at 23%. Above this oxygen concentration, there is an effect on the proliferation and differentiation of brain neurons and the formation of neurons, which promotes the activation of brain cells and the formation of brain cell networks. Therefore, learning ability such as calculation ability and memory ability is improved. On the other hand, when the oxygen concentration exceeds 30%, the mitochondria capacity in the cell mitochondria becomes saturated, and these capacities decline. Therefore, these effects are within the range of oxygen concentration of 23% to 30%. It can be said that it can fully demonstrate. In the present embodiment, the oxygen concentration of the respiratory organs of the user is a more specific value that can be effectively exhibited in the living body, that is, the oxygen concentration is set to 22% to 25%, preferably 23%. Providing equipment.

  Further, when the elapsed time for sucking oxygen at rest and the stress-related hormone (cortisol) in the blood are measured, as shown in FIG. 7, the cortisol in the blood tends to decrease with the passage of time for oxygen suction. It was found that the value of cortisol persisted when the time was 30 minutes or longer. This result is considered to be because the stress is eliminated by sucking oxygen. In addition, noradrenaline gradually increased when the suction of oxygen-enriched air was continued, and showed a higher value after stopping the suction than before the start of suction. Therefore, it is considered that the user's concentration has increased.

  Furthermore, other specific effects are 1) refresh effect (reduction of psychological stress), 2) effect of maintaining or improving concentration (especially for work such as calculation), 3) weight / body Fat reduction effect (by activation of lipolytic enzyme), 4) Blood glucose reduction effect, 5) Free fatty acid reduction effect, 6) Learning ability improvement effect, 7) Visual acuity (especially myopia) improvement effect, etc. Has confirmed the effect.

  In order to obtain these effects, it is effective to set the oxygen concentration of the air actually sucked by the user to 23%, but the same effect can be obtained even with an oxygen concentration of 22 to 25%. Moreover, the following effect can be acquired by attracting | sucking the oxygen enriched air of the said density | concentration for 30 minutes once a day. For example, as shown in FIG. 8, when the user continues to suck in oxygen-enriched air, the blood glucose level of the user decreases with the passage of the suction time. This phenomenon was not transient, and an experimental result was obtained in which the blood sugar level decreased as shown in FIG. 9 by continuing the suction of oxygen-enriched air.

  Moreover, since the oxygen-enriched membrane 2 does not permeate bacteria, viruses, molds, and allergens, sanitary oxygen-enriched air can be obtained without maintenance. In addition, since it has a function of a timer 10 that operates the suction pump 3 for a certain period of time, a timer function that controls the operation of the suction pump 3 within a predetermined time (preferably within one hour when the absorption efficiency of oxygen in the living body is high). Therefore, it can be used in a state where the oxygen suction effect can be efficiently exhibited and there is no danger of oxygen poisoning.

  In addition, the water tank 13 is provided in the flow path of the oxygen-enriched air downstream of the oxygen-enriched film 2, and the water contained in the oxygen-enriched air dissolves in the water in the water tank 13, so that the oxygen-enriched air is supplied. Water contained in the air does not reach the user's mouth. Further, by providing the water tank 13, noise due to air pulsation or vibration by the suction pump 3 can be suppressed.

  Moreover, since the water tank 13 is made detachable, the water in the water tank 13 can be excluded, so that the retained water can be prevented from being altered.

  In the present embodiment, the headphone-type fixing device 14 is used. However, a stand-type fixing device 14 may be used as long as it can maintain a predetermined distance from the user. Note that the noise felt by the user can be reduced by maintaining a predetermined distance from the user.

(Embodiment 2)
FIG. 10 shows the configuration of the discharge unit and the fixture of the oxygen enricher according to Embodiment 2 of the present invention. Since the configuration of this oxygen enricher is the same as that of Embodiment 1, the description thereof is omitted.

  As shown in the figure, the oxygen enricher in the present embodiment has a headphone-type fixture 15, and the fixture 15 is oxygen-enriched air (oxygen concentration) generated in the oxygen enricher main body 1. 30%) flow path and deformable pipe 6a, and a holding part 17 provided with a flexible tube 16 that can change the position of the user and the discharge part 5 (positioning is possible). The discharge unit 5 has a discharge port 18 serving as an outlet for oxygen-enriched air, and further includes a positioning tool 19 for maintaining a distance between the user and the discharge port 18.

  When the user sucks the oxygen-enriched air, the positioning tool 19 is brought into contact with the side of the nose to determine the position of the discharge port 18 and the user's nose, and the oxygen concentration in the nasal cavity becomes 23% at rest. I am doing so.

  In the present embodiment, the positioning tool 19 is attached to only one side of the discharge unit 5. However, by installing the positioning tool 19 at both ends of the discharge unit 5, a more accurate position can be determined. The configuration as in the present embodiment is particularly effective when the size of the nose is smaller or larger than usual.

  Further, the positioning tool 19 is provided with a scale so that the length can be changed, so that the distance from the discharge portion 5 to the tip of the positioning tool 19 can be changed. According to the shape of the face such as the user's nose. Since the position of the part 5 can be changed, more effective oxygen-enriched air can be sucked.

  In the present embodiment, the size of the discharge port 18 is set to be the same as the inner diameter (3 mm) of the pipe 6. If the discharge port 18 is throttled immediately before, the air flow is disturbed, the diffusion of the oxygen-enriched air is accelerated, and a predetermined concentration cannot be obtained. Therefore, in the present embodiment, the size of the discharge port 18 is set to the same size as the inner diameter of the pipe 6. Thus, there is no disturbance in the flow of the discharged oxygen-enriched air, and the oxygen-enriched air can be reliably sent to the user's nostrils.

(Embodiment 3)
FIG. 11 shows the configuration of the discharge section and the fixture of the oxygen enricher according to Embodiment 3 of the present invention. Since the configuration of the oxygen enricher is the same as that of Embodiment 1, the description thereof is omitted.

  As shown in the figure, the oxygen enricher in the present embodiment has a headphone-type fixing device 20, which is similar to the second embodiment in that the oxygen enrichment generated in the oxygen enricher main body 1. Holding section provided with piping 6 which is a flow path of conditioned air (oxygen concentration 30%), and flexible tube 16 which comes into contact with the user and can change the position of discharge section 5 and discharge section 5 (positioning is possible) 17.

  The discharge unit 5 has a scale 21 for the user to confirm the position. Usually, when oxygen-enriched air is sucked, the flexible tube 16 is flexible, so the position of the discharge port 18 is difficult to visually recognize.

  Therefore, in the present embodiment, the user can easily recognize the position of the discharge port 18 by providing the scale 21 at the outer position of the discharge unit 5 corresponding to the discharge port 18. Furthermore, the user can know the positional relationship between the nostril (nose hole) and the discharge port 18 by wearing the headphone-type fixing device 20 at a position where the scale 21 can be seen, so the oxygen-enriched air is sucked. It is also possible to set the discharge port 18 at an optimal position.

(Embodiment 4)
FIG. 12 shows the configuration of the discharge part of the oxygen enricher in Embodiment 4 of the present invention. Since the configuration of the oxygen enricher is the same as that of Embodiment 1, the description thereof is omitted.

  As shown in the figure, the oxygen enricher in the present embodiment has a case part 24 that constitutes the discharge part 5, and a user's nose 23 is brought into direct contact with the case part 24.

  In the present embodiment, in order to improve the efficiency of suction of oxygen-enriched air, a discharge port 18 is provided in the vicinity of the nose 23, and the positions and angles of the holes of the discharge port 18 are made different. Yes.

  That is, in FIG. 12A, the position of the discharge port 18 is removed from the position of the nostril so that the oxygen-enriched air does not directly enter the hole of the nose 23 (the nostril). When the position of the discharge port 18 is matched with the position of the hole of the nose 23, the user feels the nose 23 crawling when sucking the oxygen-enriched air, and the suction becomes difficult. Therefore, the user can suck the oxygen-enriched air without a sense of incongruity by slightly shifting the position of the discharge port 18.

  In FIG. 12B, the discharge port 18 is provided so as to discharge oxygen-enriched air in the horizontal direction with respect to the hole of the nose 23. Even in this configuration, since the oxygen-enriched air does not directly enter the hole of the nose 23, the user does not feel uncomfortable. This configuration also has an effect that water droplets generated when an oxygen-enriched film is used are less likely to collect in the discharge unit 5 and the pipe 6. In this case, the nose 23 is completely covered with the case portion 24.

  Moreover, in the discharge part 5 shown in FIG.12 (c), the discharge port 18 is the structure which supplies oxygen-enriched air toward an nasal head from an oblique direction. With this configuration, even if the nose 23 is not completely covered, the oxygen concentration near the hole in the nose 23 can be set to the target value (23%). Furthermore, by not sealing the nose 23 with the case part 24, there is no sense of incongruity when the user breathes greatly.

  Furthermore, through FIGS. 12 (a), (b), and (c), the holding unit 17 shown in Embodiments 2 and 3 is installed on the back of the user, and the discharge unit 5 is fixed from below. Even when the case portion 24 is slightly displaced, the oxygen-enriched air discharged from the discharge port 18 does not directly enter the hole of the nose 23, so that the oxygen-enriched air can be comfortably sucked.

  Further, the same effect can be obtained by holding from the lateral direction as in the second and third embodiments and fixing with the flexible flexible tube 16.

(Embodiment 5)
FIG. 13 shows the configuration of the discharge part of the oxygen enricher in Embodiment 5 of the present invention. Since the configuration of the oxygen enricher is the same as that of Embodiment 1, the description thereof is omitted.

  As shown in FIG. 13, the oxygen enricher in the present embodiment includes an oxygen sensor 26 and a mounting sensor 28 in the case portion 24 constituting the discharge portion 5. At the bottom of the case portion 24, there are provided a discharge port 18 through which oxygen-enriched air is discharged and an oxygen sensor 26 that measures the oxygen concentration in the discharge portion 5.

  The oxygen sensor 26 is connected to the control circuit 7 inside the oxygen enricher main body 1 by a cable 27, and transmits detection information to the control circuit 7. The operation of the suction pump 3 is controlled based on the oxygen concentration measured by the oxygen sensor 26 so that the oxygen concentration in the case portion 24 when the user wears the discharge portion 5 is kept at a predetermined value.

  In addition, a mounting sensor 28 is provided on the inner surface of the case portion 24 that constitutes the discharge unit 5, and the mounting sensor 28 detects that the user has worn the nasal head of the nose 23 in contact with the sensor, and according to the detection operation. Thus, the start / end of the control operation of the suction pump 3 is switched. The attachment sensor 28 does not necessarily need to detect the attachment of the discharge part 5 by contact with the nasal head, and may be provided at the end of the case part 24 to detect the attachment of the discharge part 5 by contact with the cheek. .

  FIG. 14 shows an operation flow when an oxygen enricher including the discharge unit is used.

  First, after the operation switch 8 of the oxygen enricher main body 1 is turned on, the attachment sensor 28 detects that the discharge unit 5 is attached to the user, and a warning is displayed or voiced. If it is confirmed that the discharge unit 5 is attached, the operations of the fan 11 and the suction pump 3 are started, and the oxygen enrichment operation is started. Thereafter, the oxygen concentration in the discharge unit 5 is measured to detect whether the oxygen concentration in the discharge unit 5 is a predetermined concentration (23%). Next, when the oxygen concentration is low, the control circuit 7 increases the energization amount to the suction pump 3 to increase the supply amount of oxygen-enriched air. On the other hand, when the oxygen concentration is high, the energization amount to either the fan 11 or the suction pump 3 is lowered, and the discharge flow rate is lowered to adjust the target concentration. When adjusting the oxygen concentration, it is also possible to control by the operation of the fan 11 alone. For example, by reducing the amount of current supplied to the fan 11, the upstream side of the oxygen-enriched membrane 2 is in a state where oxygen is low, so that the concentration efficiency in the oxygen-enriched membrane 2 can be reduced, and oxygen-enriched air It becomes possible to control the oxygen concentration. In this way, the oxygen concentration to the user can be adjusted by controlling the operations of the suction pump 3 and the fan 11.

  Note that the mounting sensor 28 is composed of a conductive electrode. When the mounting sensor 28 is provided on the inner surface of the flexible case portion 24, a thin metal electrode may be used as the sensor, or the case portion 24. An elastic conductive resin or conductive rubber may be provided on the inner surface, and the conductive resin or conductive rubber may be used as the sensor electrode. Resilient conductive resin or conductive rubber is made by adding metal powder such as gold, silver, copper, and aluminum, carbon black, carbon fiber, etc. to general resin or rubber to make it conductive. Therefore, it can be utilized as an electrode having elasticity. Therefore, when a soft conductive resin or conductive rubber is used as the wearing sensor 28, the pressing force applied to the face when the user wears the case portion 24 of the discharge portion 5 is eased and the degree of adhesion with the face increases. There is an advantage that air leakage can be reduced, and it is suitable as a material constituting the mounting sensor 28.

  Further, as the mounting sensor 28, a pressure sensor that senses vibration may be employed. Then, since the user's breathing state can be detected, it is possible to supply oxygen-enriched air corresponding to the breathing state. That is, when the vibration of breathing is detected, the suction pump 3 and the fan 11 are operated, and when breathing is not detected, the suction pump 3 and the fan 11 are stopped, so that oxygen-enriched air is sent to the user between breaths. Since it is not touched, it can be sucked comfortably without a sense of incongruity.

  As described above, the oxygen enricher and the oxygen enrichment method according to the present invention can obtain oxygen-enriched air that is controlled within a predetermined range in which oxygen effectively acts on a living body, and is practical. Therefore, it can be applied to all oxygen enrichers.
