The present invention provides a drug volatilization device for vaporizing a drug at room temperature, more specifically, a drug impregnating body containing a drug impregnating body and rotating a drug cartridge integrally formed with a wing, and volatilizing the drug by using a flow of air generated by the rotation. The present invention relates to a drug volatilization device capable of promoting the chemical vaporization of the drug continuously for a long time at a constant volatilization rate from the drug impregnated body.

Examples of chemical vaporizers which volatilizes and releases chemicals in a closed space (for example, inside a building, a car, or inside a tent) for exterminating pests such as mosquitoes and flies include mosquito incense, electric track mats, and liquids. Background Art An apparatus for volatilizing a drug by using thermal energy from an electric brush (liquid) or the like is known. Although chemical vaporizers of this kind generally use direct fire or electric energy as a heat energy source, there are cases where it is difficult to use them for safety or to secure a power source capable of generating sufficient heat energy. For example, in a situation where the use of direct fire, such as in a tent, is dangerous and there is no power source, it is preferable to use an apparatus capable of sufficiently volatilizing and releasing the chemical at room temperature.

An apparatus for volatilizing and releasing a medicament at room temperature without using thermal energy has been proposed before, and an apparatus for volatilizing and releasing a medicament using wind power such as a fan at room temperature is known. In this kind of apparatus, it is expected that the volatilization efficiency of a drug is greatly improved as compared with the case of simply leaving the drug (or drug impregnating body) to volatilize by using wind power from a fan or the like for volatilization of the drug.                         

Japanese Patent Application Laid-open No. Hei 10-191862 discloses a device for storing a granular drug impregnated body in a stationary impregnated container, and vaporizing the drug while stirring the drug impregnated body with wind by applying a wind from a fan to it. do.

However, in this apparatus, because the distance between the drug impregnated body and the fan is far from each other, the weak wind reaches the drug impregnated body. For this reason, in this apparatus, it is difficult to volatilize a chemical | medical agent with a fixed volatilization amount from the granule which is a chemical | medical agent impregnation body over a long period of time, and the amount of volatilization medicines reduces over time.

Japanese Patent Application Laid-Open No. 5-68459 uses a diffusion material formed by encapsulating a volatilizing agent in an envelope or a container having a membrane portion made of a gas-permeable film, or an envelope or a container having a ventilated microhole. Rotating discloses an apparatus for diffusing a volatilizing agent into air.

However, in the diffusion material used in this method, it is difficult to volatilize the drug efficiently from the entire volatilizing drug, and therefore the volatilization amount of the drug can not be reduced over time.

As described above, an object of the present invention is to solve the problem in the conventional drug volatilization device. That is, the present invention can volatilize a stable drug over a long period of time, for example, 10 days or more, without using heat energy, and as a result, prevention of volatilization decrease over time, applicability in the open air, and excellent insecticidal effect To provide a drug volatilization device having a number of advantages, such as long-lasting, high safety, good usability.

MEANS TO SOLVE THE PROBLEM The present inventors researched in order to solve the said subject, and store the chemical | medical agent impregnation in the annular hollow structure which integrated the wing part, and rotates the said hollow structure, and produces airflow from the inner peripheral surface to the outer peripheral surface, As a result, it has been found that stable volatilization performance over a long period of time (for example, a period of 30 days with use of 12 hours per day) can be obtained by promoting volatilization of the drug, thereby completing the present invention.

The feature of the chemical | medical agent volatilization apparatus of this invention is using the chemical | medical agent cartridge which consists of a ring-shaped hollow structure by which the wing part was integrally formed. Comparing the pharmaceutical cartridge of the present invention in which the wing portion is integrally formed with the hollow structure, and the pharmaceutical cartridge of the comparative example in which the hollow structure for accommodating the drug and the wing portion as a separate member, the pharmaceutical cartridge of the comparative example supports each wing portion. While a ring-shaped support portion (having a structure similar to that of the inner circumferential surface portion of the hollow structure) is required, such a support portion is unnecessary in the pharmaceutical cartridge of the present invention. Therefore, the drug cartridge of the present invention can make the wing section longer, thereby generating a stronger air flow, and can reach the drug impregnating body without losing the air flow generated by the wing section. For this reason, forming the wing portion for generating air flow integrally with the hollow structure is helpful to improve the volatilization efficiency. In addition, integration of the wing portion and the hollow structure is advantageous in terms of productivity since the wing portion and the hollow structure need not be manufactured separately and then assembled together. In particular, in the case of separately manufacturing the wing parts assembled and attached to the hollow structure, it is necessary to be careful not to block the opening provided in the inner circumferential surface of the hollow structure, the assembly and attachment is quite cumbersome. However, in the case of integrally molding the hollow structure and the wing portion, by installing the wing portion at a position other than the opening portion at the design stage, the opening portion of the inner circumferential surface of the hollow structure can not be blocked, and the productivity is greatly improved even at this advantage.

In the chemical | medical agent volatilization apparatus of this invention, the chemical | medical agent cartridge which accommodated the chemical | medical agent impregnation body is rotated by a drive means, and a chemical | medical agent is volatilized at normal temperature, while a centrifugal force acts on the chemical | medical agent impregnation body by this. In this case, the centrifugal force acting on the drug impregnated body exhibits various effects as exemplified below, and contributes to stable volatilization over a long period of time of the drug.

1) The chemical | medical agent impregnation body is previously accommodated in the chemical | medical agent cartridge. However, since the individual drug impregnated bodies are not fixed, the drug impregnated body moves when an impact is added to the drug cartridge or the drug cartridge is moved, and the storage state of the drug impregnated body in the drug cartridge changes. However, if the centrifugal force acts on the chemical | medical agent impregnation body at the time of use, the chemical | medical agent impregnation body is pushed and pressed by the outer peripheral surface side of a chemical | medical agent cartridge, and a suitable storing state is regenerated by this.

2) When the action of the centrifugal force on the drug cartridge is released, the individual drug impregnation bodies move freely to some extent by the rotation or movement of the drug cartridge, and change their positions. Therefore, the individual drug impregnated bodies can be moved by applying or releasing the centrifugal force to the drug cartridge, and the effect can be as if the drug impregnated bodies are stirred.

3) When centrifugal force is applied to the drug impregnated body, the drug inside the drug impregnated body is pushed out to the surface by centrifugal force, and the increase of the drug is promoted by the airflow generated by the rotation of the drug cartridge. Internal medicine can be effectively increased.

The magnitude of the centrifugal force is determined by the rotational state of the drug cartridge. For example, the magnitude of the centrifugal force is 1/1000 to 100 times the gravity acceleration (9.8 × 10 ² cm / s ² ), specifically 9.8 × 10 ⁻¹ cm / s ^{2 to} 9.8 × 10 ⁴ cm / s ² . desirable.

The medicine cartridge in the chemical | medical agent volatilization apparatus of this invention consists of a ring-shaped hollow structure which has a hollow part for accommodating a chemical | medical agent impregnation body. The size of the hollow structure varies depending on the amount of the chemically impregnated body to be stored in order to obtain a desired amount of volatilization. In addition, although the shape of the said chemical | medical agent cartridge is arbitrary, what has a spherical cross section of a hollow structure can be used, for example.

The hollow structure is composed of a main body member having a ring-shaped groove, and a cover member which is a cover of the groove, which is preferable in terms of manufacturing the hollow structure, storing the chemically impregnated body into the hollow structure, and the like.

The annular hollow structure constituting the drug cartridge of the present invention has an opening on its outer circumferential surface and its inner circumferential surface, and the opening serves as a vent for vaporizing the drug. The opening can be arbitrarily designed as long as it has sufficient breathability, but it is preferable to set the ratio between the total area of the opening and the entire area of the peripheral surface of the medicine cartridge, for example, from 1:10 to 1: 2.                     

The shape of the opening may be, for example, a configuration in which a net is fixed to an opening slit or a holder. Preferred are a plurality of opening slits formed in parallel.

Moreover, it is preferable to attach a shielding member, such as a sealing tape, to the opening part of a chemical | medical agent cartridge for the purpose of preventing a chemical | medical agent from volatilizing from the chemical | medical agent impregnation body accommodated in the chemical | medical agent cartridge before use. Since the said shield member must be removed at the time of use, the adhesive tape etc. which can peel easily are preferable.

The chemical | medical agent cartridge of this invention is integrally molded with the wing part extended toward the center of the said hollow structure in the position which does not block the opening part of the inner peripheral surface of a hollow structure. And the wing portion has a shape such as to promote the passage of airflow from the inner peripheral surface to the outer peripheral surface of the hollow structure by the rotation of the drug cartridge.

Although there is no restriction | limiting in particular about the length of the said wing part, It is preferable that it is at least 5 mm or more. The intensity of the airflow generated by the rotation of the drug cartridge can also be adjusted by changing its shape. For example, the longer the wing, the stronger the airflow generated. Moreover, when a wing part is made into a half moon shape or a curved shape, a wing part can send more air to the outer peripheral surface of a hollow structure.

At the center of the ring of the hollow structure constituting the medicine cartridge, there is a rotation support shaft connected to a drive means for rotating the medicine cartridge, and an axis center portion connected to the rotation support shaft. The shaft portion may be any configuration as long as it can loosely connect the drug cartridge and the rotary support shaft. For example, a circumferential member that fits loosely with the rotation support shaft can be used.                     

The shaft center portion is coupled to the hollow structure by a plurality of spoke portions. The number of spokes is arbitrary and it is preferable to join the hollow structure and the shaft center by, for example, 2 to 4, in particular 3 or 4 spokes.

In the present invention, the pharmaceutical cartridge is preferably made of a polyester resin in terms of processability and usability. Examples of the polyester resins include polyethylene terephthalate, polybutylene terephthalate, polyarytate and polycarbonate. Among these, polyethylene terephthalate is particularly preferred.

In addition, in this invention, the intrinsic viscosity of the said polyethylene terephthalate is 0.7 dl when it measures at 25 degreeC in the mixed solvent of phenol / 1, 1, 2, 2- tetrachloroethane (weight ratio = 1/1). It is preferable that it is / g or less. When the intrinsic viscosity of polyethylene terephthalate is in this range, the strength and moldability of the pharmaceutical cartridge of the present invention are better, and the pharmaceutical component can be released slowly and efficiently without loss during use. The resin may also include lubricants (e.g., paraffin wax, aliphatic esters, aliphatic alcohols, etc.), stabilizers (e.g., calcium, zinc-containing compounds, etc.), impact strength enhancers, antioxidants, ultraviolet absorbers, weather resistance modifiers, pigments, You may add a processing aid or a heat resistance improving agent in the range which does not impair the characteristic of this invention.

The chemical | medical agent impregnation body used in the chemical | medical agent volatilization apparatus of this invention can change with respect to the shape, and is granular, for example, spherical shape, an ellipsoid shape, an egg shape, a columnar shape, a columnar, a film | membrane. The object, disc shape, square plate shape, irregular shape, etc. may be sufficient.

Particularly preferred are granular drug impregnated bodies having an average outer diameter of 3 mm to 10 mm and 1.3 times or more the size of the opening. By employing the drug impregnated body having such a size and shape, the drug inside the drug impregnated body gradually migrates to the surface, and it is possible to maintain a stable amount of volatilization over a long period of time. On the other hand, for example, in the drug impregnation body whose average outer diameter is smaller than 3 mm, the drug is rapidly volatilized rapidly, and there is a problem in the persistence of the insecticidal effect.

The drug impregnated body has a porosity (% of internal volume remaining as voids without filling the drug impregnated body) in the drug cartridge 20% to 70%, preferably 25% to 65%, particularly preferably It is stored at 30% to 60%. If the porosity is less than 20%, air is difficult to flow through the drug cartridge, and sufficient drug volatilization amount cannot be secured. On the contrary, when the porosity exceeds 70%, the time for contact between the air and the drug impregnated body is shortened when passing through the drug cartridge, so that a sufficient amount of chemical vaporization cannot be ensured.

It is preferable that the said chemical | medical agent impregnation body contains the chemical | medical agent which can adjust the amount of volatilization per hour to 0.01-0.6 mg, and can exhibit sufficient insecticidal effect with this chemical amount. As such a pharmaceutical agent, a volatile pyrethroid type insecticide is mentioned especially. The volatilizing pyrethroid insecticide is, for example, a fluorine-substituted benzyl alcohol ester compound represented by the formula (1).                     

Formula 1

Wherein X and Y represent the same or differently hydrogen atom, methyl group, halogen atom or trifluoromethyl group, and Z represents hydrogen atom, fluorine atom, methyl group, methoxymethyl group or propargyl group.

As a specific example of the compound represented by the said Formula (1), 2, 3, 5, 6- tetrafluorobenzyl- chrysanthite, 2, 3, 5, 6- tetrafluorobenzyl-2, 2-dimethyl-3- ( 1-propenyl) cyclopropanecarboxylate, 4-methyl-2, 3, 5, 6-tetrafluorobenzyl-xanthate, 4-methyl-2, 3, 5, 6-tetrafluorobenzyl-2 , 2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate, 4-methyl-2, 3, 5,6-tetrafluorobenzyl-2, 2-dimethyl-3- (2,2-dichloro Vinyl) cyclopropanecarboxylate, 4-methoxymethyl-2, 3, 5, 6-tetrafluorobenzyl-xanthate, 4-methoxymethyl-2, 3, 5, 6-tetrafluorobenzyl- 2, 2-dimethyl- 3- (1-propenyl) cyclopropanecarboxylate, 2, 3, 4, 5, 6-pentafluorobenzyl-2, 2-dimethyl- 3- (2-chloro- 2- Trifluoromethylvinyl) cyclopropanecarboxylate or 4- Propargyl-2, 3, 5, 6-tetrafluorobenzyl-3- (1-propenyl) -2,2-dimethylcyclopropanecarboxylate. Moreover, as a compound other than what is represented by the said General formula (1), 4-methoxymethyl-2, 3, 5, 6- tetrafluorobenzyl-2, 2, 3, 3- tetramethylcyclopropanecarboxylate, and 4 -Propargyl-2, 3, 5, 6-tetrafluorobenzyl-2, 2, 3, 3- tetramethylcyclopropanecarboxylate is illustrated.

In addition, the compound contains asymmetric carbon and double bonds, and optical isomers and geometric isomers are present. However, of course, any mixture between the isomer and the isomer may be used as the medicament.

Moreover, the said chemical | medical agent impregnation body may contain 1 type of drugs, or may contain the mixture of 2 or more types of drugs.

On the other hand, it is not preferable to use aspirin, prarethrin, and the like, which have been conventionally used as an active ingredient of a heating evaporative insecticide, in the chemical vaporization apparatus of the present invention because of their insufficient volatilization at normal temperature. In addition, even if it is a pyrethroid insecticide, a drug such as empentrin that exhibits a high vapor pressure has an effective insecticidal effect, and thus requires an amount of 2 mg or more per hour, and thus is not preferable.

The drug impregnated body preferably contains 60 mg or more of the drug. When content of a chemical | medical agent is less than 60 mg, there exists a possibility that the sustainability of an insecticidal effect may arise. At the time of impregnation of a chemical | medical agent, a solvent, a diluent, surfactant, a dispersing agent, a slow-release agent, etc. can be used as desired, and the various impregnation means conventionally known can be employ | adopted. The drug impregnant may contain a stabilizer, a perfume, a colorant, an antistatic agent, and the like, as long as it does not interfere with the volatilization of the drug, and furthermore, such as hinokithiol, carbon, post-roll, citronol, cinnamon aldehyde, and the like. It is also possible to add other highly volatile insecticides and repellents such as insect repellents, mite insecticides, fungicides, deodorants and the like to prepare a multipurpose pharmaceutical composition.

Examples of the material of the chemically impregnated body include cellulose carriers such as paper, pulp and viscose, synthetic resin carriers such as ethylene-vinyl acetate resin and olefin polymer, and inorganic carriers such as calcium silicate. Especially, it is preferable to use as a base material the paper, pulp, a cellulose carrier, a synthetic resin carrier, or a mixture thereof derived from nature.

In the chemical | medical agent volatilization apparatus of this invention, you may mix and store in the chemical | medical agent cartridge many types of chemical | medical agent impregnation bodies of different size, a shape, the chemical | medical agent to be contained, a material, etc. in an appropriate ratio. By simultaneously using a drug impregnating body having different volatilization properties and efficacy, the drug volatilization device of the present invention can achieve a complex insecticidal and insect repellent effect.

In the chemical | medical agent volatilization apparatus of this invention, the drive means which rotates the said chemical | medical agent cartridge consists of a motor and a power supply, and is integrated in the apparatus main body. In view of prolonging the usable time of the drug volatilization device, it is preferable that the motor is a power saving type. For example, it is suitable that the rotation speed of 500-2000 rpm can be continued for 300 hours or more by the battery of voltage of 2.0-3V. The power supply may be a battery, for example, a 3.0-6.0V DC battery or a 3.0-6.0V DC power supply created by lowering the voltage by inserting an AC adapter into an AC power supply. In addition, even when an AC power source is used with an emphasis on more stable chemical vaporization performance and economical efficiency, it is preferable to design such that a battery can be used together for outdoor use.

In the chemical | medical agent volatilization apparatus of this invention, since the said chemical | medical agent cartridge rotates at the time of use, when it is set as the structure which exposed the said chemical | medical agent cartridge, a problem in terms of safety etc. will arise. Therefore, in the chemical | medical agent volatilization apparatus of this invention, a chemical | medical agent cartridge is put in the accommodating part of an apparatus main body, and is further covered by a cover. However, it is preferable that an opening is provided in the cover so that the cover does not inhibit volatilization of the drug. Therefore, the cover of the structure which provides opening parts, such as a slit-like and mesh shape, around the cover and prevents a finger | toe etc. from touching the rotating medicine cartridge is preferable. In addition, when the medicine is completely consumed, it is necessary to replace the medicine cartridge, so that the cover is freely mounted on the main body of the apparatus.

In the drug volatilization device of the present invention, various factors for each of the above-described components, for example, the size of the drug cartridge, the total area of the opening provided in the drug cartridge, the size and shape of the wing, the amount of the drug impregnated body to be housed in the drug cartridge, By varying the filling rate, the type and amount of the drug contained in the drug impregnated body, the size and shape of the drug impregnated body, the rotation speed of the drug cartridge, and the like, the volatilization amount of the drug from the drug impregnated body and the duration of the drug volatilization may be arbitrarily selected. Can change. The chemical | medical agent volatilization apparatus comprised so that a chemical | medical agent may volatilize from the chemical | medical agent impregnation body at 0.01-0.6 mg volatilization over 1 hour, and over 180 hours is especially preferable at the point of actual use.

The chemical | medical agent volatilization apparatus of this invention may be further equipped with the chemical | medical agent residual quantity display function and / or the battery residual quantity display function which are visually seen by a liquid crystal. Although these display functions are controlled by a built-in central processing unit (CPU) or a memory, for example, when displaying the remaining amount of drugs in response to a plurality of cartridges (normally two to three) having different effective usage times, It is suitable to install a magnetic sensor or an optical sensor on the cartridge facing side of the device, and to recognize the type of cartridge by the CPU receiving the signal sensed by the sensor. In addition, the effective use time is, for example, 240 hours (20 days by using 12 hours a day), 360 hours (30 days by using 12 hours a day), and 720 hours (12 hours a day). To 60 days).

In addition, various methods of controlling the drug remaining amount display function are possible, for example, a built-in RC oscillation circuit that oscillates a unique frequency pulse when the motor is operated under a voltage of a predetermined amount or more, and detecting the oscillation pulse and the basis thereof. The method of controlling the measurement of the motor operation time and the conversion to the chemical | medical agent residual amount can be employ | adopted. Normally, a memory is provided and the timer data is retained even after the power is turned off. In addition, it is preferable to set so that the measurement program of the motor operation time is reset when the reset switch is pressed after replacing the cartridge.

The shape and the display design of the chemical | medical agent residual amount display part may also be arbitrarily provided, for example, the bar-shaped liquid crystal display part of the number corresponding to each cartridge type may be provided, and may be displayed so that it may be replaced by one liquid crystal display part.

The battery remaining amount display function may include a display portion, a voltage drop determination circuit, and a CPU that controls the display function based on voltage recognition and the recognition of the battery. The shape and the display design of this battery remaining amount display part are also arbitrary, and may be integrated with the said chemical | medical agent remaining amount display part further, and may be provided in the separate body.

The method for displaying the remaining amount of the medicine or the battery can be appropriately employed, and can be represented by, for example, a large or small bar, or a reduction in the number of divided marks. For clarity, the display may blink at the end point.

Hereinafter, the apparatus of the present invention will be described in more detail with reference to the drawings.

As shown in FIGS. 1-4, the medicine cartridge 2 inserted in the accommodating part 11 of the apparatus main body 1, and rotationally supported freely contains the chemical | medical agent impregnation body 3 in it, It is rotated by the motor 4 driven by the battery 5. In addition, the medicine cartridge 2 is covered by the cover 6 so as not to be exposed.

The apparatus main body 1 is a member which puts the chemical | medical agent cartridge 2 in the accommodating part 11, and contains the drive means which consists of the motor 4 and the battery 5. In FIG. Moreover, it is preferable that the apparatus main body 1 has the power switch 12 for controlling the drive / stop of the chemical | medical agent cartridge 2 on the surface, and also the opening part 13 is provided in order not to obstruct the volatilization of a chemical | medical agent. .

In addition, the holder 14 is installed on the back of the apparatus main body 1 (opposite to the surface on which the pharmaceutical cartridge is installed) to be attached to the garment, or the strap 15 is attached to the hook portion 15 provided on the upper portion of the apparatus main body 1. Hanging around the neck makes it easy to carry the drug volatilization device. In addition, in terms of portability, the size of the apparatus main body 1 is preferably as small as possible.

As shown in FIG. 4, the drug impregnation body 3 is housed in the hollow structure 21 of the drug cartridge 2. The drug impregnation body 3 does not necessarily need to be densely packed in the hollow structure 21. This is because the drug impregnation body 3 is pushed by the centrifugal force generated by the rotation of the drug cartridge 2 on the outer circumferential surface side of the drug cartridge 2 so that the drug impregnation body 3 is dense in the vicinity of the outer circumferential surface of the drug cartridge 2. This is because the state of charge is achieved.

The size of the chemical | medical agent impregnation body 3 needs to be larger than the size of the outer peripheral surface opening part 22 and the inner peripheral surface opening part 23 at least from a viewpoint of preventing the scattering.

The motor 4 is placed under the medicine cartridge 2 and is attached to the apparatus main body 1 by the motor mounting part 16. The motor 4 is connected with the rotation support shaft 24 of the medicine cartridge 2, and the rotation support shaft 24 is further connected with the shaft center 25 of the medicine cartridge 2. The connection between the motor 4 and the rotary support shaft 24, and also the rotary support shaft 24 and the shaft center portion 25 must be strong enough so that no slip occurs when the motor 4 is driven. 3) When all the medicines inside are consumed and the medicine cartridge 2 is replaced, it is preferable that the medicine cartridge 2 and the motor 4 can be easily separated.
