Hereinafter, the present invention will be described in more detail, but the present invention is not limited thereto.
As shown in FIG. 1, the finger disinfection device of the present embodiment is a finger disinfection device using ultraviolet rays having a wavelength of 190 nm to 230 nm. The disinfection device 1 of the present embodiment includes a main body 10 having an insertion port 11 into which a disinfectant's hand is inserted and a finger disinfection chamber 13 connected to the insertion port, and an ultraviolet irradiation member 20 installed in the main body 10. The irradiation completion mechanism A is provided so as to be able to irradiate the ultraviolet rays of the ultraviolet irradiation member 20 substantially over the entire area of the user's fingers or almost uniformly.
Since the internal structure of the main body differs depending on what kind of configuration is adopted as the irradiation completion mechanism A, the details will be described below for each embodiment. In the description of the second embodiment and the following embodiments, duplicate explanations will be avoided. Therefore, the description in the first embodiment is appropriate for points not particularly detailed.

[First Embodiment]
In the first embodiment, as shown in FIGS. 2 to 4, the insertion port 11 is formed by a rectangular opening, and the finger disinfection chamber 13 is continuously provided in the insertion port 11 inside the main body 10. Adjacent to the hand disinfection room 13, a division room 30 in which the ultraviolet irradiation member 20 is arranged is provided to isolate the ultraviolet irradiation member 20 from the hand disinfection room.
As shown in FIG. 1, the appearance of the main body has a rectangular parallelepiped shape in this embodiment. In FIG. 2, since only the main part of the main body is shown, the portions forming the finger disinfection chamber 13 and the division chamber 30 are shown, but in a preferred embodiment, a rectangular parallelepiped as shown in FIG. 1 by an outer wall member covering them is shown. The body shape. As such an outer wall member, a plastic material and a metal material that can be used for this kind of device can be used without particular limitation.
In the description of the present embodiment, an insertion port 11 and a finger disinfection chamber are formed, and a configuration in which either the right or left hand is inserted is exemplified. The disinfection chamber may be sized so that both hands can be placed side by side so that both hands can be disinfected at the same time.
The irradiation completion mechanism A in the present embodiment is a mechanism that enables irradiation mainly to substantially the entire area of the user's fingers. As the irradiation completion mechanism A, the wall surface (inner wall surface) 13a facing the division chamber 30 in the finger disinfection chamber 13 is tapered, and the reflective member 40 is arranged in the finger disinfection chamber 13. Further, two UV lamps as the ultraviolet irradiation member 20 are provided at a distance from each other.
Here, "substantially the entire area of the user's fingers" means both the front side and the back side of the palm and the part between the fingers when the fingers are opened as shown in FIG. Preferably, it means that the ultraviolet irradiation is performed at the irradiation amount described later.

<Hand disinfection room>
As shown in FIG. 2, the wall surface 13a of the hand disinfection chamber 13 has a straight cross section and a tapered shape, so that the width thereof becomes narrower from the insertion port 11 side to the back. The angle θ1 (angle with respect to the vertical line from the side of the upper surface of the main body) of the wall surface 13a is preferably 3 to 30 °. The reason for the taper shape is that when the finger is inserted, the thickness of the fingertip is smaller than that on the wrist side, and the irradiation efficiency of ultraviolet rays is improved by matching the shape of the hand. Further, when the disinfectant solution described later is used, the adhesion rate of the disinfectant solution to the fingers is improved, and the disinfection efficiency is also improved.
The wall surface (wall surface provided with the ultraviolet irradiation member) 13b is the bottom surface (surface facing the insertion port) in the direction perpendicular to the upper surface (surface provided with the insertion port) 13d provided with the insertion port 11. The 13c is provided parallel to the upper surface 13d.
The height h of the finger disinfection room (see FIG. 2) is preferably 20 cm to 35 cm so that even a person with a large hand can disinfect with the fingers fully extended, and the width w (see FIG. 4). ) Is preferably 15 cm to 20 cm, and the depth d (see FIG. 4) is preferably 5 cm to 30 cm, more preferably 5 cm to 20 cm.

It is configured not to. Specifically, the inner wall surface of the main body is completely sealed so that the UV lamp and the energizing device that supplies power to the UV lamp are not exposed in the hand disinfection room. Even at the location where the spray nozzle is installed, the area around the spray nozzle is sealed with a commonly used sealing material so that the alcohol-based disinfectant sprayed to the outside of the main body does not seep out.
The area of the insertion opening provided on the upper surface of the main body 10 needs to be sufficiently large so that the finger can be inserted without touching the edge of the opening when inserting the finger. On the other hand, although the ultraviolet rays used in the present invention have little effect on the human body, it is preferable to prevent the leakage of ultraviolet rays as much as possible, and when the mechanism for spraying the disinfectant solution described later is provided, the leakage of the disinfectant solution is prevented. It is preferable to prevent it. If there is no leakage of UV rays or antiseptic solution, the disinfectant solution should be inhaled without imposing an excessive burden on the medical staff even if the daily disinfection frequency of the medical staff is significantly increased. There is no such thing, and it can be used suitably. From the viewpoint of this configuration, the shape of the insertion slot in the present embodiment is a rectangle with the least wasteful gap (in the present embodiment, it is rectangular and both ends are circular). However, the shape of the insertion port is not limited to such a shape, and various shapes such as a circular shape can be adopted as long as a hand can be inserted. The area of the insertion slot is preferably 30 cm ² to 500 cm ² , and more preferably 100 cm ² to 250 cm ² .

The upper surface 13d and the wall surface 13b are provided along the respective surfaces. The wall surface 13a is arranged along each surface except for the bottom surface 13c side. Specifically, it is provided by attaching the following reflective member forming material to each surface. However, the bottom surface 13c is provided with a reflective member arranged so as to lean diagonally from below the wall surface 13a (toward the bottom surface side). That is, at the portion where the intersection line between the bottom surface 13c and the wall surface 13a is located, the reflection member 40c is arranged so as to cover the intersection line and contact only the edge portion of the reflection member with the bottom surface 13c and the wall surface 13a. At this time, it is preferable that the angle θ2 between the reflective member 40c on the bottom surface side and the bottom surface 13c is 15 to 45 °. All the reflective members 40c on the bottom surface side may be arranged at the above angles, but in the present embodiment, as shown in FIG. 2, they are provided along the bottom surface by attaching a mirror to the bottom surface on the wall surface 13b side. The portion 40c'is formed.
Further, as shown in FIG. 2, the reflective member 40 is also arranged as a reflective member 40e on the side surface 13e of the finger disinfection chamber 13. As shown in FIG. 3, the portion 3 to 7 cm below the reflective member 40e is provided so as to be inclined by θ3 with respect to the bottom surface 13c. It is preferable that θ3 is 30 to 60 ° from the viewpoint of irradiating the fingers with ultraviolet rays without disturbing the fingers. This makes it possible to irradiate ultraviolet rays from all around the fingers.
The reflective member 40 is not particularly limited as long as it has a high reflectance of ultraviolet rays of 222 nm and is durable, and can be formed by using various materials. There are various materials such as stainless steel, aluminum, titanium, brass, and gold. In particular, aluminum is preferably used because of its high reflectance. It is also possible to use a material obtained by coating the surface of these metals with a dielectric multilayer film, or an anodized aluminum material. However, it cannot be used when the surface is coated with a normal polymer material or an inorganic glass material other than quartz.
The reflectance of ultraviolet rays at 222 nm is preferably more than 50%, more preferably 70% or more, and most preferably 80% or more.
Commercially available products can also be used, for example, UV reflective mirrors manufactured by Sigma Seiki Co., Ltd., trade name "TAFE series"; UV reflective materials manufactured by ALANOD, trade name "MIRO-UV series", etc. are used. be able to.

<Division room>
The division chamber 30 is separated from the hand disinfection chamber 13 by a wall surface 13b formed of a transparent glass material plate material. The plate material is sealed with a sealing material or the like at the installation location on the upper surface and the bottom surface thereof, whereby the division chamber 30 is sealed to at least the hand disinfection chamber. The upper portion 31 (upper surface side) of the division chamber 30 is a distribution chamber, and wiring for supplying electric power to the UV lamp 20 is installed.
Inside the partition chamber 30, two UV lamps 20 as ultraviolet irradiation members are arranged in the vertical direction (direction from the insertion slot side to the bottom surface side). That is, in the present embodiment, the ultraviolet irradiation member is arranged only on one side of the finger disinfection chamber.
Further, the wall surface 13b may be formed by fitting the above plate material into the arranged wall surfaces provided on both the upper and lower sides (from the insertion port side to the bottom surface side).

<Ultraviolet irradiation member>
Two UV lamps 20 as ultraviolet irradiation members are arranged apart from each other in the vertical direction in order to form the irradiation completion mechanism A. Each UV lamp is a columnar lamp, and the lamps are arranged so that the longitudinal direction (axial direction) thereof is the horizontal direction (direction parallel to the upper surface 13d). In addition, assuming that the finger is to be inserted into the finger disinfection chamber, the first UV lamp is placed at a position 5 to 10 cm (d1 shown in FIG. 2) from the insertion port, and this 1 is placed. It is preferable to arrange the second UV lamp at a position 13 to 17 cm (d2 shown in FIG. 2) from the second UV lamp.
As the UV lamp that irradiates ultraviolet rays of 190 nm to 230 nm, an excimer lamp, an LED (Light emitting diode) or the like can be used. When an excimer lamp containing KrBr or KrCl is used as a light source, the synchrotron radiation may contain a component having a wavelength longer than 230 nm. In that case, the emission of light having a wavelength longer than 230 nm is suppressed by a bandpass filter or the like. Is preferable. Alternatively, it is preferable to use it within a range in which the irradiation amount of the contained long wavelength light does not harm the human body. As the ultraviolet rays, ultraviolet rays having a peak top of 206 to 208 (207) nm (excimer lamp containing KrBr) or 221 to 223 (222) nm are used from the viewpoint of actual availability. Further, an ultraviolet LED such as a diamond LED, an AlGaN-based LED, or an MgZnO-based LED that emits light of these wavelengths can also be used. As the UV lamp using an excimer lamp, for example, those described in Patent Documents 1, 2, 3 or 5 and the like can be used, but the UV lamp is not limited thereto.
As the UV lamp in the present embodiment, it is preferable to use a UV lamp having an irradiation intensity of 20 mw / cm ² or less just below the center of the tube in terms of downsizing of the apparatus and cost. The irradiation intensity on the irradiated surface is preferably 10 mw / cm ² or less, more preferably 5 mw / cm 2 or less, and most preferably 2 mw / cm 2 or less. The irradiation amount is preferably 50 mJ / cm ² or less, more preferably 10 mJ / cm ² or less, and most preferably 5 mJ / cm ² or less. The lower limit of the irradiation intensity is about 0.1 mw / cm ² , and the lower limit of the irradiation amount is about 0.2 mJ / cm ² . In order to achieve such irradiation intensity and uniformly irradiate the fingers, it is possible to increase the number of lamps used, but this is not preferable from the viewpoint of cost and miniaturization of the device. It is preferable to arrange the reflective member in the above-mentioned devised arrangement form.

<Irradiation completion mechanism>
In the present embodiment, as described above, the irradiation completion mechanism includes a reflecting member 40 that reflects ultraviolet rays installed in the main body, and a plurality of UV lamps as ultraviolet irradiation devices are arranged separately from each other. The reflective member 40 is arranged so as to be inclined at a predetermined angle with respect to the irradiation direction of ultraviolet rays by the ultraviolet irradiation member.

<Other members>
(Disinfectant spray member)
In the present embodiment, the ejection ports 51 and 53 as the disinfectant liquid spraying member for spraying the disinfectant solution into the hand disinfection chamber in the main body 10 have the spray nozzle in the width direction of the main body as shown in FIGS. 2 and 3. It is provided by arranging two in the central portion so as to be separated from each other in the vertical direction. The spout 51 is arranged on the bottom surface, and the spout 53 is provided so as to be located substantially in the center in the vertical direction. The spout 51 and the spout 53 are arranged upward so that the disinfectant is sprayed upward (in the direction of the arrow in FIG. 2).
As the spray nozzle used at this time, a commercially available spray nozzle can be used without particular limitation, but preferably, an average particle size of 500 μ or less, more preferably 200 μ or less, and most preferably 100 μ or less can be realized. A spray nozzle capable of spraying a small amount of liquid over a wide area is preferable. Specifically, for example, a product name "KB nozzle", "KBN nozzle", etc. manufactured by Ikeuchi Co., Ltd. can be used. That is, a nozzle having a main body spout and a closer and capable of spraying fine mist in an annular or circular shape, such as a main body spout and a nozzle in which the closer is made of ceramic, is used. Can be done.
Although not particularly shown, the disinfectant device of the present embodiment can supply a pipe for supplying the disinfectant liquid connected to the spray nozzle, a pump provided by connecting the pipes, and the disinfectant liquid to the spray nozzle in addition to the spray nozzle. It is equipped with a tank to be housed in the main body, and a disinfectant solution supply means composed of these is arranged outside the main body (inside if necessary).
The amount of one spraying by the spray nozzle is adjusted to be 0.2 mg / cm ² to 2 mg / cm ² , and is preferably 10 ml or less, although it depends on the internal volume of the housing.
As the disinfectant liquid sprayed by the disinfectant liquid spraying member, an alcohol-based disinfectant can be preferably mentioned.
Examples of the alcohol-based disinfectant include the following.
A quick-drying alcohol-based disinfectant mainly containing an aqueous solution of ethanol, propanol, or a mixture of both. Iodine-based disinfectant mainly composed of alcohol solution of iodine (iodine tincture) and povidone iodine (complex of polyvinylpyrrolidone and iodine); quaternary ammonium mainly composed of alcohol solution of benzalkonium chloride and benzethonium chloride Salt-based disinfectant; Amphoteric surfactant-based disinfectant mainly composed of alcohol solution of alkyldiaminoethylglycine hydrochloride; Biguanide-based disinfectant mainly composed of alcohol solution of chlorhexidine gluconate

In addition to disinfecting power and safety, quick-drying alcohol-based disinfectants mainly containing an aqueous solution of ethanol, propanol, or a mixture of both are most preferable because they do not require quick-drying, water, or drainage facilities. The mixing ratio of water and alcohol in this aqueous solution is preferably 50% by volume or more, and more preferably 60% by volume or more. Further, it is preferably 95% by volume or less, and more preferably 85% by volume or less. When the blending ratio of alcohol is low, it tends not to exert a sufficient sterilizing and disinfecting effect, and drying after application tends to be delayed. On the other hand, when the proportion of alcohol is high, the effect of sterilizing and disinfecting is not sufficient, the drying becomes too fast, and the irritation to the skin tends to be strong. When safety such as low ignitability is important, the alcohol concentration is preferably 50% by volume to 60% by volume. The alcohol-based disinfectant may contain a disinfectant containing a small amount of benzalkonium chloride, benzethonium chloride, and chlorhexidine gluconate, and if necessary, a small amount of carboxyvinyl polymer or cellulose-based water-soluble. It may contain a thickener such as a sex polymer compound. It can also contain a moisturizer or the like to prevent rough hands.

(Other parts)
It is preferable that "irradiating" is displayed during ultraviolet irradiation. As the ultraviolet irradiation display device, it is preferable to install an energizing lamp or a fluorescent substance that emits light by receiving ultraviolet rays of 222 nm.
In addition, although not shown in particular, a sensor that detects the insertion of a hand is provided near the opening, and when this sensor detects the intrusion of a hand, the spray nozzle sprays the alcohol-based disinfectant 1 to 2 seconds later. At the same time, ultraviolet rays are irradiated by a UV lamp.

<Usage>
Next, a disinfection method using the disinfection device 1 of the present embodiment will be described.
First, the hand is put into the main body 10 from the insertion port 11 in the direction of the arrow, and the hand is put into the finger disinfection room. Then, a sensor (not shown) reacts to spray the alcohol-based disinfectant from the spray ports 51 and 53, and at the same time, the UV lamp 20 irradiates the ultraviolet rays. At this time, it is possible to sufficiently disinfect the space between the fingers and the crotch part by having the user put his / her hands open as much as possible.
In the disinfection device of the present embodiment, as described above, a spray nozzle is provided at the center of one surface (the center of the front when the hand is used as a reference), and UV lamps are provided at the upper and lower positions of the hand. Since the reflective surface is installed, it is possible to spray the disinfectant on the entire hand, and the disinfection by UV irradiation by the UV lamp 3 and the disinfection by spraying the disinfectant by the spray nozzle 7 are simultaneously and effective. It is possible to carry out without disturbing.
Since it is configured in this way, the spraying time can be short, and can be 3 seconds or less, and further can be 1 second or less.
Here, the alcohol-based disinfectant is treated so that the amount of the alcohol-based disinfectant adhered to the object to be disinfected is 0.2 mg / cm ² to 2 mg / cm ² , and the ultraviolet irradiation amount is 0.2 mJ / cm ² to 5 mJ /. Most preferably cm ²
It is preferable to perform ultraviolet irradiation and disinfectant treatment at the same time. Here, "at the same time" means that the spraying by the device for spraying the disinfectant and the start of the irradiation by the device for irradiating the ultraviolet rays are controlled so as to be simultaneous by a normal control circuit or control mechanism, and are performed together. Means the state. Therefore, even if there is an error of about a slight difference (within 1 to 3 seconds) caused by the normal device, it is within the range of "simultaneously". Thereby, the desired effect of the present invention can be obtained more efficiently.
Since the disinfection device of the present embodiment is provided with an irradiation completion mechanism, it is possible to sufficiently irradiate the shadow portion of the fingers with ultraviolet rays. Specifically, since two UV lamps are provided on the upper and lower sides at a predetermined interval as described above, it is possible to irradiate a sufficient amount of ultraviolet rays on the entire finger, although only on one side. .. Further, the scattered ultraviolet rays reach the wall surface 13a, the bottom surface 13c, and the top surface 13d on the opposite side of the UV lamp without hitting the hands, and these lights are transmitted to the reflecting member 40, particularly the reflecting member 40a provided at an inclination. Since the reflective member 40c is provided at an angle, it is possible to efficiently irradiate the surface of the hand opposite to the UV lamp and the portion of the crotch of the finger with the reflected ultraviolet rays. As a result, the entire finger can be irradiated with ultraviolet rays, so that sterilization can be performed effectively. In addition, the distance between the ultraviolet irradiation tube and the fingers can be freely determined, and the thickness of the irradiation device can be kept small even when the distance is large. Therefore, it is possible to make the device compact. In this way, each part of the finger is treated with ultraviolet irradiation and an alcohol-based disinfectant at the same time, so that disinfection is completed in a short time. It is preferable to use an alcohol-based disinfectant because the disinfection speed is high.

[Second Embodiment]
Next, the second embodiment will be described with reference to FIG.
In the disinfection device 101 of the embodiment shown in FIG. 5, two insertion ports 111 and 111 are formed by two rectangular openings. The two insertion ports 111 and 111 are arranged side by side with a rectangular dividing member 131 for separating the two insertion ports 111 and 111. The arrangement is such that the longitudinal directions of the two insertion openings are parallel to the longitudinal directions of the dividing member 131, respectively. In the main body 110, two finger disinfection chambers 113 corresponding to the two insertion openings 111 and 111 and partitioned via the division chamber 130 are provided. In the division room 130, two UV lamps are arranged as ultraviolet irradiation members as in the first embodiment.
The wall surfaces 113b and 113b on both sides of the partition chamber 130 are formed of a glass material that transmits ultraviolet rays, respectively, like the wall surface 13b in the first embodiment.
Further, the wall surface of the division chamber 130 is provided with a normal sealing means such as a sealing material so that the two finger disinfection chambers 113 and 113 are completely separated as independent sealed spaces via the division chamber 130. It is sealed.
The two finger disinfection chambers 113 and 113 both have the same shape as that of the first embodiment, and the reflective member 140 also has the same shape and is provided at the same position.
Also in the present embodiment, as in the first embodiment, the irradiation completion mechanism A is a mechanism capable of irradiating substantially the entire area of the finger of the user. The irradiation completion mechanism A is also configured by the point that the reflection member 140 and the UV lamp are provided at two distances from each other, as in the first embodiment.
In this embodiment as well, it can be used in the same manner as in the first embodiment. Since it is configured as described above, the disinfection device of the present embodiment can disinfect both hands at the same time, and disinfects both hands at once with the same two UV lamps as in Example 1. Therefore, it is possible to disinfect the fingers more efficiently, in a space-saving manner, and in an energy-saving manner.

[Third Embodiment]
Next, the third embodiment will be described with reference to FIG.

The total light transmittance of the light diffuser is 5% or more, and the diffusion rate is 5% to 95%. Preferably, the total light transmittance of the light diffuser is 20% to 95%, and the diffusion rate is 30% to 95%. More preferably, the total light transmittance of the light diffuser is 20% to 95%, and the diffusion rate is 40% to 95%.
Total light transmittance is measured according to JIS7361.
The diffusion rate (D) is calculated according to the following equation.
D = (B20 + B70 / (2 x B5)) x 100
θ = light receiving angle Tθ = light transmittance of θ degree Bθ = Tθ / cosθ
As the light diffuser, a commercially available product can also be used. Specifically, a synthetic quartz plate manufactured by Tosoh EDH with a roughened surface, a synthetic quartz frosted glass diffuser manufactured by Edmond Optics Co., Ltd., Co., Ltd. "UV fused silica def user" manufactured by Optical Solution can be used.
In this embodiment as well, it can be used in the same manner as in the first embodiment. Since it is configured as described above, the disinfection device of the present embodiment enhances the homogeneity of the intensity of the irradiation light applied to each part of the finger due to the presence of the light diffuser, and sterilizes each part of the finger. It is possible to suppress sexual variation.
