Description

Specification

Inhaler technical field

The present invention relates to an inhaler used for respiratory assistance or therapy. Background art

There are roughly three types of clinically used medical inhalers. These are a diffuser-type humidifier, a spray / atomization type ultrasonic nebulizer, and a jet nebulizer using water droplet splitting by the bench lily effect. Both have a humidifying function, and can be heated and inhaled by using a heater in combination. In addition, it is connected to oxygen at a concentration of about 40% by volume and used for oxygen therapy.

It is humidified and used for respiratory support, or it is used for treatment by adding a drug. The purpose of use of these inhalers is classified into two types. One is for depositing drug and water particles to the trachea and bronchi. The droplets (water droplets) have a particle size of 15 microns or more. The other is to allow the drug and water particles to reach the alveoli further, and the droplets (water droplets) have a particle size of 5 microns or less. Some of the latter are characterized by the use of 0.3 micron ultrafine particles. In any case, conventional treatment devices called nebulizers (nebulizers) are products that only consider the size of droplets (water droplets), that is, the particle size.

On the other hand, when water is given high energy and split as water droplets, the water undergoes ion dissociation (H +, OH—), and positive ions (positive air Ions) and negative ions (negative air ions).

This phenomenon is well known as the Leonard effect (waterfall effect). Furthermore, the physiologically active effects of these positive and negative ions are described in Table 1 in Keiichi Morishita, “Water and Life,” published by Midori Shobo, p. 77.

In Table 1, a positive ion refers to a case where the ratio of the negative ion (n—) to the positive ion (n +) (ion ratio; n—Zn +) is 0.5 or less. If the ion ratio is 2 or more, it is called a negative ion. When the ion ratio is between 0.5 and 2, it is considered that positive ions and negative ions are almost balanced.

The normal pH value of blood is 7.35 to 7.45, which is weakly alkaline. Thus, it has been known that small air ions have a physiological activity. However, the performance of inhalers has not been enhanced from the viewpoint of small air ions.

Next, the structures of the conventional inhaler Humidifier (hereinafter referred to as HD) and the jet nebulizer (hereinafter referred to as JN) using the bench lily effect are shown in Figs. 7 and 8, respectively. This will be described below.

As shown in FIG. 7, the HD 101 is provided with a water tank 102, a diffuser tube 103, a supply tube 104 communicating with the diffuser tube 103, and a suction port 105. Consists of By providing the air diffuser tube 103, the supply air is humidified. The supply air is supplied from the supply port 106 of the HD 101, passes through the supply pipe 104, and is sent to the diffuser pipe 103 in the water tank 102. Since the air diffuser tube 103 is porous, the air passing therethrough tends to be fine bubbles. Air sent to diffuser 103 is fine

\

It rises in the aquarium 102 as bubbles. In this way, the air is humidified and becomes humidified air, which is supplied from the inlet 105. Although not shown, heated air can be obtained by using a heater inside the HD 101. Next, JN will be described with reference to FIG.

The same parts as those in FIG. 7 are denoted by the same reference numerals, and detailed description is omitted. As shown in Fig. 8, JN 10 using the bench lily effect 7 has a water tank 102, a supply pipe 104, and a suction pipe 108. The supply pipe 104 has a supply port 106 and a nozzle 109 at the tip of the supply pipe 104, and a suction pipe 108 near the nozzle 109 at the tip of the supply pipe 104. It has a structure with an outlet 110. The air for inhalation or high concentration oxygen for inhalation sent from the supply port 106 to the supply pipe 104 is blown out from the nozzle 109 at the tip of the supply pipe 104. Due to the negative pressure effect of the high-speed air flow at that time, that is, the venturi effect, the humidifying water for humidification in the water tank 102 or the medical solution for treatment is sucked from the suction pipe 108 and sprayed from the outlet 110. You. The supply air or high-concentration oxygen requires high-speed airflow at the nozzle 109, and is used under pressure.

The sprayed humidified water or chemical liquid becomes sprayed water droplets, and is mixed with the suction air or the high-concentration oxygen for suction sent from the supply port 106 to the supply pipe 104 in the spray mixing section 111. In addition, it is mixed with the indoor air sent from the indoor air suction port 112, and adjusted to an appropriate oxygen concentration, humidity, or an appropriate drug concentration. Next, it is sent to the inlet 105 for treatment or respiratory support. ^ Since there is no special drop separation mechanism, it is supplied with water droplets of various sizes. Although not shown, the heater is appropriately heated and supplied according to the usage conditions. In FIG. 8, the dotted arrow indicates the flow direction of water or the chemical solution. The dashed-dotted arrow indicates the flow direction of the indoor air. The two-dot chain arrow indicates the flow direction of the supply air or high concentration oxygen. The solid arrows indicate the flow direction of the mixed air and the conditioned air adjusted to the appropriate oxygen concentration, humidity, or appropriate drug concentration. High-concentration oxygen means that the oxygen concentration is about 40% by volume. Or more. The case where the oxygen concentration is about 98% by volume to 100% by volume is also included. Supply air may be used as room air. The air ion content was measured for the HD and JN described above and another conventional inhaler, an ultrasonic nebulizer. The method of measuring the positive ion amount (n +) and negative ion amount (n—) at the inlet of each type of inhaler is as follows, and the measurement results are shown in Table 2.

1. The comparison is indoor air.

2. HD (See Fig. 7): Blow oxygen at a flow rate of 5, 10, and 15 (1 / in) into purified water heated by a heater at a concentration of 50% by volume. Then, each ion amount is measured by an ion tester at a position 10 cm away from the inlet.

3. JN (see Fig. 8): Flow oxygen adjusted to a concentration of 35% by volume at flow rates of 5, 10 and 15 (lZmin). Then, the amount of each ion is measured in the same manner as for HD while aspirating the purified water in the container by the bench lily effect.

4-Ultrasonic nebulizer: Put purified water into the container on the ultrasonic vibrator and flow oxygen adjusted to a concentration of 35% by volume at flow rates of 5, 10 and 15 (IZmin). Then, the purified water is evaporated, and the amount of each ion is measured in the same manner as for HD.

The ion tester used for the measurement has a mobility of 0.4 cm ² ZV · s or more.

Table 2 shows the results. The steam humidifier heated by a heater or the like hardly generates air ions. In other words, there is almost no air ion function. On the other hand, JN and ultrasonic nebulizers are considered to be The amount of gas ions generated is very large. However, the ion ratio is about 0.5, which is considered to be almost positive from the viewpoint of air ions. Table 2 Air ions in the room and various inhalers

That is, in the conventional inhaler, positive ions are generated in a larger amount than negative ions. This is because positive ions stimulate the sympathetic nerve and have physiological effects such as vasoconstriction, as shown by the action of air ions in Table 1. An object of the present invention is to provide a compact inhaler capable of suppressing generation of positive ions, generating a large amount of negative ions as compared with positive ions, and capable of separating water droplets with high performance. . In addition, the nature of the inhaler product requires compactness. However, using a water droplet separation mechanism that separates water droplets to suppress the generation of positive ions and generates a larger amount of negative ions than positive ions increases the overall size of the device, making it difficult to achieve compactness. It also has the problem of being Disclosure of the invention

BEST MODE FOR CARRYING OUT THE INVENTION In examining the biologically active effects of negative ions on living organisms due to water splitting, first consider whether water-derived negative ions may enhance the biological activity of living organisms. Preliminary test was conducted. The preliminary test conditions are shown below. As a model for atopic dermatitis, mice develop chronic contact dermatitis in the ears of mice. Next, we exposed to negative ions derived from water and generated by water splitting, and examined the possibility that negative ions could enhance the physiological activity. The comparative tests were performed on a group exposed to normal air (hereinafter referred to as a control group) and a group exposed to negative ions generated by corona discharge (hereinafter referred to as an electric ion group). The group exposed to negative ions derived from water and generated by water splitting is hereinafter referred to as the true group. Temperature and humidity: 22 ° C ± 1.5. C, 55% ± 10% RH, average negative ion amount are: Masaki group: 1,200,000 Zcc, Electric ion group: 3 0, 0 000 Zee (However, only in this group, the ozone concentration was detected at 310 ppb), and the control group: 0 pcs / cc.

Chronic contact dermatitis develops in the mouse ears, and the thickness of the earlobe, which is thickened by the lesion, is measured. Table 3 (average of n = 10) shows the start date (day 0) and the thickness of the earlobe (mm) after 14 days as a typical example.

Table 3 Changes in earlobe thickness (unit: mm)

As shown in Table 3, the Masaki group (the group exposed to negative ions derived from water) showed good results with a significant difference from the control group. In other words, it is suggested that negative ions from water may enhance the biological activity of living organisms. In other words, it has a beneficial effect on the living body. The electric ion group (group exposed to negative ions generated by corona discharge) is worse than the control group, which may be due to the effect of ozone. However, even with the same negative ion, the biologically active effect of the living body is different between negative ions originating from water and due to water splitting and negative ions generated by a discharge phenomenon (electrical type) such as corona discharge. Seems to be.

Next, in a preliminary test, the use of negative ions generated from water and water splitting, which had the effect of enhancing the biological activity of living organisms, was used to reduce the lactate concentration in arterial blood and the biological activity in vivo. Hyperactivity was verified. The device of the present invention is used as a negative ion supply source. The comparison was performed using the conventional JN (see Fig. 7).

In the experiment, neurosurgical patients with high lactate levels in arterial blood of 1.5 (mmol / l) or more were randomly selected from 20 patients and divided into two groups. The values measured during the experiment were as follows: the amount of negative ions: about 2,500 Zee, the amount of positive ions: about 400 / cc, and the ion ratio (n− / n +) was 6.2. It was five. The ratio of the amount of negative ions is very high. This device is referred to as the “negative device”. On the other hand, in the nebulizer, the amount of negative ions: about 200,000 Zee, the amount of positive ions: about 100,000 pieces / cc, and the ion ratio (n-/ n +) is 0.2. there were. The ratio of the amount of positive ions was very high.

This device is referred to as the “primary device”. After adjusting the oxygen concentration to 40% by volume, pour it into both devices, and inhale through the inlet in the following procedure.

One group (10 people) inhales the first 4 hours from the negative device and the remaining 4 hours from the positive device. Conversely, the other group (10 people) inhale the first 4 hours from the positive device and the remaining 4 hours from the negative device. Table 4 shows the results measured every hour.

Table 4 Time change of blood lactate value (average value of n = 10) Negative device inhalation-Positive device inhalation Positive device inhalation → Negative device inhalation time (h) Lactate value (mmol / 1) Time (h) Lactate value ( mmol / 1) Initial value 3.2 3 Initial value 2.90

Main unit 4 2. 9 3 Main unit 4 1. 3 9 (Note) Suction port temperature: 23 ± 1 ° C Humidity: 93 ± 3% RH As shown in Table 4, first use a negative device and add 40% by volume with negative ions derived from water. Lactate levels in arterial blood begin to drop after inhalation of oxygen for 4 hours. Next, after the elapse of 4 hours, switching to JN inhalation of the positive device, and inhaling 40% oxygen for 4 hours together with a large amount of positive ions, the lactate concentration in the arterial blood starts to rise. Conversely, after inhaling for the first 4 hours with the positive device, switching to the negative device after 4 hours, and inhaling for 4 hours, the lactate concentration in the arterial blood was flat with the inhalation of the positive device. It began to drop sharply. Such a remarkable effect was completely unexpected at first and was first revealed by the present invention.

This effect is not found in the positive ions, and it is considered that only the negative ion derived from water enhances the biological activity of the living body. The mechanism of the action of enhancing biological activity in vivo by negative ions derived from water is presumed as follows. This is thought to be because water-derived negative ions are absorbed into the body to eliminate active oxygen, which inhibits aerobic metabolism in vivo, and to promote oxidative phosphorylation, which is an ATP-forming reaction.

Negative ions derived from water accelerate the ATP generation reaction in vivo, lowering the concentration of oxygen to be inhaled, shortening the oxygen inhalation time, or reducing the lactate concentration in arterial blood even with normal air be able to. In other words, oxygen treatment or respiratory support can be performed more safely. The water splitting or water drop splitting referred to in the present invention does not cover a steam-type humidifying inhaler heated by heat or the like. The mechanical force expressed by water splitting or droplet splitting is applied to water, It refers to a method of ion dissociating water by applying high energy. The mechanical force is a force that uses the vibration energy of an ultrasonic vibrator, a force that uses the bench lily effect like JN, a force that uses injection such as a nozzle type, a collision, etc., a rotating disk type, This is a force that uses injection, collision, and centrifugal force, such as a set of impellers and a centrifugal type.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. The same parts as those in the conventional example are denoted by the same reference numerals, and detailed description is omitted.

(Embodiment 1)

As shown in Fig. 1, the main body 1 of the inhaler is equipped with an ultrasonic vibrator 2 at the bottom and a water tank 102 containing water or a chemical solution, and an atomizing section 3 provided at the top of the water tank. A blower 4 for blowing air to the atomizing section 3, a partition plate 5 having an opening 6 provided above the atomizing section 3, a wire mesh 7 provided above the partition plate 5, and a wire mesh. And a wire mesh rotation motor 8 for rotating the motor. In addition, a suction port 105 is provided at the top of the main body 1 of the inhaler.

In the above configuration, the water or the chemical solution in the water tank 102 is sprayed or atomized by the ultrasonic vibrator 2 provided at the bottom of the water tank 102. The sprayed or atomized water or fine water droplets of the chemical solution are sent to the atomizing section 3 by the air blower 4 to be mixed with fine water droplets and sent to the partition plate 5. The relatively large water droplets are separated and removed by the baffle plate action and the inertia separation action of the partition plate 5, and then sent to the wire mesh 7 from the opening 6 of the partition plate. The wire mesh 7 is rotated by a wire mesh rotating motor 8. The water in the air mixed with fine water droplets from which relatively large water droplets have been removed by the partition plate 5 or the water droplets of the chemical solution are Causes water droplets to re-divide and re-aggregate. Then, the fine water droplets are separated, and the fine water droplet mixed air is converted into a smaller ultra-fine water droplet mixed air. By this ultra-fine droplet formation, positive ions charged in the larger fine droplets are separated. As a result, the ion balance ratio between positive ions and negative ions, which are generated in approximately equal amounts during water splitting, is disrupted. The ion balance ratio of the negative ions at the inlet 105 is more than twice as large as the positive ions. The ultra-fine water-droplet mixed air containing high amount of negative ions and having high humidity and biological activity is sent to the inlet 105 and used for respiratory assistance or treatment.

The partition plate 5 performs relatively large water droplet separation, but in combination with the fine water droplet separation by the rotation of the wire mesh 7, the water droplet separation is performed to such an extent that the ion balance is disturbed so that the negative ions become more than twice the positive ions. If possible. For this reason, whether the partition plate 5 should be one-stage, two-stage, or two-stage or more, or not used should be appropriately designed based on the positive / negative ion ratio to be obtained and the air volume. Just decide. Next, the device specifications are described below.

Main unit dimensions: diameter 105 mm x height 200 mm, dividers: two, diameter of opening of dividers: 10 mm, diameter of wire mesh: 98 mm, wire mesh pitch: 16 to 25 0 mesh, rotation speed of wire mesh: 1, 000 to 4,000 RPM, ultrasonic oscillation frequency of ultrasonic transducer: 1.2 MHz. FIG. 2 is a plan view of the wire mesh 7. Oxygen adjusted to an oxygen concentration of 40% by volume with an oxygen concentration controller is introduced into the device at each flow rate (1 / min) of 5, 10, and 15.

Table 5 shows the results of measurements with an ion tester and a thermo-hygrometer at a position 10 cm from the inlet. Table 5 Negative ion positive ion amount, temperature and humidity

(Note) Temperature: 25.8 ° C, 92% RH

The supply of high-concentration oxygen to the inhaler is performed by connecting to oxygen with an oxygen concentration of 40% by volume adjusted by an oxygen concentration controller.

Depending on the condition of the patient and the treatment state, it may be connected to a higher oxygen concentration of 40% to 100% as appropriate. As a device for supplying high-concentration oxygen, an oxygen cylinder that supplies 98% to 100% pure oxygen, an oxygen generator that generates oxygen by chemical reaction or water electrolysis, There are oxygen concentrators and others that separate and concentrate oxygen or adsorb and desorb gas molecules by zeolite, etc. to concentrate oxygen in the air. The device is appropriately selected and used depending on the use conditions such as the oxygen concentration to be administered and the place of use. An appropriately selected high-concentration oxygen supply device is connected to an inhaler that generates negative ions from water and water splitting, and is used for respiratory support or treatment. In addition, for ease of handling, an inhaler that generates negative ions due to water splitting due to water splitting may be incorporated into a device that supplies high-concentration oxygen.

Figure 3 shows the state of water droplet splitting and water droplet aggregation at the rotating wire mesh. Fig. 1 shows the state of water droplet splitting and water droplet aggregation.

Fig. 3 is a schematic diagram, and it may not be possible to accurately represent the situation visually confirmed. The material atomized by the ultrasonic vibrator is sent from the upper inlet 9 and passed through the wire mesh 7 rotating through the shaft 10 by the wire mesh rotating motor 8. The rotation of the wire mesh 7 causes the re-splitting and aggregation of the atomized fine water droplets and the separation of the fine water droplets, resulting in ultra-fine water droplets. In the upper region 11 of the wire mesh 7, into which fine water droplets due to atomization flow, there are countless fine water droplets, which are opaque due to atomization and fine water droplets.

On the other hand, fine water droplets are separated and removed from the lower region 12 of the rotating wire mesh 7 and are transparent. The ultra-fine water droplets after the separation of the fine water droplets are discharged from the outlet 13. Figure 3 shows that the rotation of the wire mesh 7 causes water droplet re-division, water droplet aggregation, and separation of fine water droplets at the same time. As shown in FIG. 4, when the wire mesh 7 is provided with the tube 14 and the wire mesh rotating motor 8 rotates the wire mesh 7 and the tube 14, fine water droplets are efficiently separated. As a result, the ion balance between the generated negative ions and positive ions is disrupted, and a large amount of negative ions can be generated as compared to the positive ions.

(Embodiment 2)

The same parts as those in the conventional example and the first embodiment are denoted by the same reference numerals, and detailed description is omitted.

As shown in Fig. 5, a cyclone separator 15 is provided above the atomization section 3 in the body 1 of the inhaler.

In the above configuration, the air mixed with fine water droplets including the fine water droplets atomized by the ultrasonic vibrator 2 and the blowing device 4 is supplied to the cyclone separator. Sent on evening 15. The air mixed with fine water droplets is sent from the cyclone inlet 16 into the cyclone separator 15 and forms a swirling flow.

Then, the fine water droplets are centrifuged, the ion balance between the positive ions and the negative ions is broken, and the air becomes ultra-fine water-droplet mixed air containing a large amount of negative ions. Sent to In this way, it is used for respiratory assistance or treatment.

Here, the relationship between the ultrasonic oscillation frequency of the ultrasonic transducer and the generated negative ions was examined. Atomization ultrasonic vibrator (ultrasonic oscillation frequency: 1.2 MHz) and cleaning ultrasonic vibrator (ultrasonic oscillation frequency: 400 kHz) that generate different water particle diameters in water splitting And were used.

The air was blown to the atomizing section 3 by the blower 4 using a swirling flow, and the wind speed was set to 1.0 mZ sec and 2.5 m / sec. Table 6 shows the experimental results. The state of water droplets in the atomization unit 3 is that the central atomized particle diameter is about 3 microns in the case of an ultrasonic oscillator for atomization. Cloudy water droplets are also seen from the outlet 17 of the cyclone separator 15 in a cloudy state from the atomization section 3 to the inside of the cyclone separator 15. On the other hand, in the case of the ultrasonic transducer for cleaning, a water column of about 5 cm is formed at the center of the swirling flow of the atomizing section 3 and becomes steamy from there. At the exit 17 of the cyclone separator, the outlet 17 was no longer steamy. The experimental results with the ultrasonic oscillators at 100 kHz and 500 kHz also yielded almost the same ion ratio.

The inhaler containing a large amount of negative ions aimed at by the present invention can be obtained by adjusting the ultrasonic oscillation frequency range of the ultrasonic oscillator to 100 kHz to 500 kHz. Table 6 Comparison of ultrasonic nebulizer and cyclone separator

(Embodiment 3)

The same portions as those of the conventional example, the first embodiment, the second embodiment, and the like are denoted by the same reference numerals, and detailed description is omitted.

As shown in FIG. 6, a wire mesh 7 and a wire mesh rotating motor 8 for rotating the wire mesh are provided downstream of the spray mixing section 1 11 in the main body 107 of the inhaler.

In the above configuration, the mixed air of fine water droplets including the fine water droplets mixed in the spray mixing section 1 1 1 1 is caused by the rotation of the wire mesh 7 to re-divide the atomized fine water droplets and separate them into fine water droplets. Ultra-fine water droplets. As a result, relatively large fine water droplets that are positively charged are separated and removed, and the ion balance between the positive ions and the negative ions is disrupted, generating a large amount of negative ions. Then, it is sent to the inlet 105 and used for respiratory assistance or treatment. In this way, it is possible to provide a small inhaler that effectively generates negative ions.
