Usually, disinfection pumps are installed in multiple places in the hospital, and posters and the like are used to call attention to hand hygiene. However, in actual medical practice, it is said that the compliance rate of hand hygiene of medical staff is less than 40%. For this reason, the medical staff themselves serve as a medium, and inpatients may be infected.
　特許文献１には、掌を殺菌するために、手首に装着する掌用光触媒殺菌ライトが開示されている。この掌用光触媒殺菌ライトでは、ＬＥＤライトケースが、装着ベルトを介して手首に装着できる。ＬＥＤライトケースは、光触媒反応を促進する発光源であるＬＥＤと、電源部と、スイッチを有し、使用者は、手に手袋をはめる。そして、ＬＥＤの光は、酸化チタンを塗布した手袋の掌部分に、照射することで、手の裏（手の平）を、光触媒反応により殺菌するようになっている。 Patent Document 1 discloses a photocatalytic sterilization light for the palm to be worn on the wrist in order to sterilize the palm. In this palm photocatalytic sterilization light, the LED light case can be worn on the wrist via a wearing belt.

<Overview of portable UV sterilizer 1>
FIG. 1 shows a state in which the first embodiment of the portable ultraviolet sterilizer of the present invention is attached to the forearm. FIG. 2 is a front view of the portable ultraviolet sterilizer 1 shown in FIG. FIG. 3 is a block diagram showing a configuration example of the portable ultraviolet sterilizer 1 shown in FIG. FIG. 4 is a diagram showing a state in which fingers are sterilized by the portable ultraviolet sterilizer 1 shown in FIG.
　図１に示すように、図１に示す携帯型紫外線殺菌装置１は、医療従事者等の使用者の前腕５００に対して着脱可能に装着される。携帯型紫外線殺菌装置１は、好ましくはリング状に形成されており、リストバンド型のウェアラブルデバイスである。携帯型紫外線殺菌装置1は、前腕５００に着脱可能に装着するだけで、使用者の手指の全体または全体領域に対して、人体へのダメージの無い短波長の紫外線（ＵＶ－Ｃ）を照射することで、手指の手の表（手の甲）と手の裏（手の平）に、特に手指の先端（爪と指の間）を含む全体を自動的に継続して連続的に殺菌できる。 As shown in FIG. 1, the portable ultraviolet sterilizer 1 shown in FIG. 1 is detachably attached to the forearm 500 of a user such as a medical worker. The portable ultraviolet sterilizer 1 is preferably a ring-shaped wearable device of a wristband type. The portable ultraviolet sterilizer 1 irradiates the entire or entire area of the user's fingers with short-wavelength ultraviolet rays (UV-C) that do not damage the human body by simply attaching the portable ultraviolet sterilizer 1 to the forearm 500 detachably. As a result, the entire surface (back of the hand) and the back of the finger (palm), especially the tip of the finger (between the nail and the finger), can be automatically and continuously sterilized.
　携帯型紫外線殺菌装置１は、適切な短波長の特定の波長域の紫外線の照射時間、タイミング、角度で自動照射され、装着しているだけで、手指の全体の殺菌状態を適切に保つ機能を有する。短波長の紫外線は非常に強力な殺菌能力を発揮でき、手指衛生の遵守率を維持することにより、例えば院内感染の発生率を低減できる。これにより、薬剤耐性菌（ＭＲＳＡ）等の院内感染に伴う患者や医療従事者の感染を防ぎ、医療費の削減が図れる。 The portable ultraviolet sterilizer 1 has a function of automatically irradiating ultraviolet rays in a specific wavelength range with an appropriate short wavelength at an irradiation time, timing, and angle, and simply wearing the portable ultraviolet sterilizer 1 to maintain an appropriate sterilized state of the entire finger. Have. Short-wavelength ultraviolet light can exert a very strong bactericidal ability, and by maintaining the compliance rate of hand hygiene, for example, the incidence of nosocomial infection can be reduced. As a result, infections of patients and medical staff due to nosocomial infections such as drug-resistant bacteria (MRSA) can be prevented, and medical expenses can be reduced.
　図１と図２に示すように、携帯型紫外線殺菌装置１は、医療従者や患者等の使用者の前腕５００に対して、着脱可能に装着するための装着部２を有する。装着部２は、好ましくはリング状であり、好ましくは弾性変形可能な樹脂で紫外線を通す材質で作られていて、透光性と抗菌性を有するエンジニアリングプラスチックやシリコン等により作られている。装着部２は、前腕５００に装着した状態で回転しないように保持できる。装着部２は、手指５０１側から装着部２の開口部３内に通すことで、前腕５００に装着できる。装着部２は、できる限り小さく、薄く、しかも軽くする。これにより、使用者は、携帯型紫外線殺菌装置１を腕の前腕５００に装着して、通常の治療行為や看護業務が行い易い。 As shown in FIGS. 1 and 2, the portable ultraviolet sterilizer 1 has a mounting portion 2 for detachably mounting on the forearm 500 of a user such as a medical staff or a patient. The mounting portion 2 is preferably ring-shaped, preferably made of an elastically deformable resin that allows ultraviolet rays to pass through, and is made of engineering plastic, silicon, or the like having translucency and antibacterial properties. The mounting portion 2 can be held so as not to rotate while being mounted on the forearm 500. The mounting portion 2 can be mounted on the forearm 500 by passing it from the finger 501 side into the opening 3 of the mounting portion 2. The mounting portion 2 should be as small, thin and light as possible. As a result, the user can easily perform normal medical treatment and nursing work by attaching the portable ultraviolet sterilizer 1 to the forearm 500 of the arm.
＜装着部２＞
　図２に示すように、装着部２は、電源部４と、２つの紫外線発生部５と、制御部６と、センサ９と、スイッチ１０を備える。必要に応じて２つの反射部７，８を設けてもよい。このように２つの反射部７，８を設けることで、手の表と手の裏に紫外線をまんべんなく照射できる。
　装着部２の開口部３には、好ましくは図１に示す前腕５００の外周面に密着できるような密着部分２Ｂを有する。これにより、装着部２がリング状であっても、装着部２は、密着部分２Ｂにより前腕５００の外周面に密着した状態で回転しないように保持できる。これにより、２つの紫外線発生部５，５がそれぞれ発生する紫外線は、手の表と手の裏から外れないように、手の表と手の裏、特に手指の先端（爪と指の間）に照射できるので、手の全体を殺菌できる。電源部４と紫外線発生部５と制御部６と反射部７，８とセンサ９は、例えば装着部２と密着部分２Ｂにおいて、内蔵するようにして配置されている。スイッチ１０は、装着部２の外周側に配置されている。
　開口部３を大きくし、前腕５００に容易に確実に装着できるようにするため、装着部２をほぼ２分割し一方が枢軸されるようにし、開口部３が大きく開く側の装着部２の適所に例えば面ファスナなどにより係止部を設けるようにしてもよい。こうすることで、装着部２の前腕５００への装着と、装着部２の前腕５００からの取り外しが容易になる。 <Mounting part 2>
As shown in FIG. 2, the mounting unit 2 includes a power supply unit 4, two ultraviolet light generating units 5, a control unit 6, a sensor 9, and a switch 10. If necessary, two reflecting portions 7 and 8 may be provided. By providing the two reflecting portions 7 and 8 in this way, it is possible to evenly irradiate the front and back of the hand with ultraviolet rays.
The opening 3 of the mounting portion 2 preferably has a close contact portion 2B that can be brought into close contact with the outer peripheral surface of the forearm 500 shown in FIG. As a result, even if the mounting portion 2 has a ring shape, the mounting portion 2 can be held in close contact with the outer peripheral surface of the forearm 500 by the close contact portion 2B so as not to rotate. As a result, the ultraviolet rays generated by the two ultraviolet generating parts 5 and 5 can be applied to the front and back of the hand, especially the tips of the fingers (between the nails and fingers) so as not to come off from the front and back of the hand. , Can sterilize the whole hand. The power supply unit 4, the ultraviolet ray generating unit 5, the control unit 6, the reflecting units 7, 8 and the sensor 9 are arranged so as to be built in, for example, in the mounting unit 2 and the close contact portion 2B. The switch 10 is arranged on the outer peripheral side of the mounting portion 2.
In order to make the opening 3 large so that it can be easily and securely attached to the forearm 500, the attachment portion 2 is divided into approximately two parts so that one of them is pivotal, and the appropriate position of the attachment portion 2 on the side where the opening 3 opens widely. The locking portion may be provided by, for example, a hook-and-loop fastener. By doing so, it becomes easy to attach the attachment portion 2 to the forearm 500 and to remove the attachment portion 2 from the forearm 500.
＜各構成要素の配置例＞
　図２に例示するように、電源部４と制御部６とセンサ９は、密着部分２Ｂ側に配置されている。２つの紫外線発生部５，５が装着部２内に配置されている。２つの反射部７，８を設ける場合、装着部２内に配置される。図３に示すように、制御部６は、スイッチ１０と、電源部４と、センサ９と、紫外線発生部５，５に、電気的に接続されている。電源部４は、小型の一次電池、例えば単３形，単４形，ボタン型のアルカリ乾電池、あるいは、単３形または単４形の小型の充電池（二次電池）を採用でき、電源部４は、制御部６に動作電源を供給する。スイッチ１０は、使用者がオンすることで、制御部６が紫外線発生部５，５を駆動して、紫外線発生部５，５から後で説明する特定の波長域の紫外線を照射させる。センサ９は、紫外線発生部５，５から特定の波長域の紫外線が照射されているかどうかを検知して、制御部６に知らせる。 <Example of arrangement of each component>
As illustrated in FIG. 2, the power supply unit 4, the control unit 6, and the sensor 9 are arranged on the close contact portion 2B side. Two ultraviolet light generating parts 5 and 5 are arranged in the mounting part 2. When two reflecting portions 7 and 8 are provided, they are arranged in the mounting portion 2. As shown in FIG. 3, the control unit 6 is electrically connected to the switch 10, the power supply unit 4, the sensor 9, and the ultraviolet light generating units 5 and 5. The power supply unit 4 can employ a small primary battery, for example, an AA, AAA, button type alkaline dry battery, or a small AA or AAA rechargeable battery (secondary battery), and the power supply unit 4 can be used. 4 supplies an operating power supply to the control unit 6. When the switch 10 is turned on by the user, the control unit 6 drives the ultraviolet light generating units 5 and 5 to irradiate the ultraviolet light generating units 5 and 5 with ultraviolet rays in a specific wavelength range to be described later. The sensor 9 detects whether or not ultraviolet rays in a specific wavelength range are emitted from the ultraviolet ray generating units 5 and 5, and notifies the control unit 6.
　＜紫外線発生部５の光源１１＞
　図２に示すように、２つの紫外線発生部５，５は、同じ構成であり、複数の紫外線照射用の光源１１を有する。小型、軽量の光源としては好ましくはＵＶＣ－ＬＥＤを用いる。各光源１１は、装着部２の内周面２Ｃに沿って内周面２Ｃから所定離間して装着部２の半径方向外向きに向けて間隔をおいて配置されている。光源１１の設定数は、デバイスのコスト低減と、電源部４による長時間の駆動を実現するためと、軽量化のために、少ないほうが良い。各光源１１が発生する紫外線の波長としては、短波長の紫外線（ＵＶ－Ｃ）である１００～２８０ｎｍの波長域の内の一部の特定の波長域である２００～２３０ｎｍを採用している。このように２００～２３０ｎｍの特定の波長域を採用する理由は、次の通りである。 <Light source 11 of the ultraviolet generation unit 5>
As shown in FIG. 2, the two ultraviolet generation units 5 and 5 have the same configuration and include a plurality of light sources 11 for irradiating ultraviolet rays. A UVC-LED is preferably used as a small and lightweight light source. Each light source 11 is arranged along the inner peripheral surface 2C of the mounting portion 2 at a predetermined distance from the inner peripheral surface 2C and at intervals toward the outward direction in the radial direction of the mounting portion 2. The number of light sources 11 set should be small in order to reduce the cost of the device, realize long-term driving by the power supply unit 4, and reduce the weight. As the wavelength of the ultraviolet rays generated by each light source 11, 200 to 230 nm, which is a specific wavelength range of 100 to 280 nm, which is a short wavelength ultraviolet ray (UV—C), is adopted. The reason for adopting such a specific wavelength range of 200 to 230 nm is as follows.
　太陽光線の場合、地上まで到達する紫外線は、ＵＶ－Ａ（長波長）がほとんどであることと、人体は太陽光線を利用し適合するようにつくられていること等により、過剰な暴露と体質的な不適合を除けば、通常あまり紫外線による障害を受けることはない。しかし、人体に悪影響を及ぼすといわれている紫外線の波長は、短波長であり、特にＵＶ－Ｃ（短波長：１００～２８０ｎｍ）のように非常に強いエネルギによってＤＮＡ損傷（がんの誘発）させる作用がある。 In the case of the sun's rays, most of the ultraviolet rays that reach the ground are UV-A (long wavelength), and the human body is made to fit using the sun's rays, so excessive exposure and constitution Except for the incompatibility, it is usually less susceptible to UV damage. However, the wavelength of ultraviolet rays, which is said to have an adverse effect on the human body, is a short wavelength, and DNA damage (induction of cancer) is caused by extremely strong energy such as UV-C (short wavelength: 100 to 280 nm). It works.
　ところが、ＵＶ－Ｃ（１００～２８０ｎｍ）の中でも、一部の特定の紫外線波長域である２００～２３０ｎｍに関しては、タンパク質への浸透が著しく悪いことが分かっている。この特定の波長域（２００～２３０ｎｍ）は、ＭＲＳＡ（約１μｍ）を貫通してＭＲＳＡを死滅させることができるが、細胞レベルではヒト細胞核（約１０～２０μｍ）まで、組織レベルでは皮膚上皮や目の水晶体の感受性細胞まで到達することがない。
　なお、光源１１の表面を覆うように、光拡散部（不図示）を設けてもよい。この光拡散部としては、エンボス加工などで微細な凹凸を形成したポリカーボネート樹脂のシートで形成したり、両凸レンズ状で大きさ（平均粒径１０μｍ程度）に形成した架橋ポリメタクリル酸メチルを塗布により形成することで得られる。 However, among UV-C (100 to 280 nm), it is known that the penetration into proteins is remarkably poor at 200 to 230 nm, which is a specific ultraviolet wavelength range. This particular wavelength range (200-230 nm) can penetrate MRSA (about 1 μm) to kill MRSA, but at the cellular level up to the human cell nucleus (about 10-20 μm) and at the tissue level the cutaneous epithelium and eyes. It does not reach the sensitive cells of the crystalline lens.
A light diffusing portion (not shown) may be provided so as to cover the surface of the light source 11. The light diffusing part is formed of a polycarbonate resin sheet having fine irregularities formed by embossing or the like, or is coated with crosslinked polymethylmethacrylate formed into a biconvex lens shape (average particle size of about 10 μm). Obtained by forming.
　一例として、従来の２５４ｎｍの殺菌用ランプ（紫外線の波長ピーク２５４ｎｍ）を使用した際には、メシチリン耐性黄色ブドウ球菌（ＭＲＳＡ型ＵＳＡ３００）と、ＡＧ１５２２標準ヒト線維芽細胞の死滅の比較で、いずれも高いレベルで死滅する。しかし、２０７ｎｍのエキシマランプを使った際の同様のデータでは、ＵＶ照射量が増えても、ヒト線維芽細胞の死滅が、ＭＲＳＡに比べて低く抑えられる。このことから、特定の波長域の紫外線（２００～２３０ｎｍ）が、ＭＲＳＡの死滅には有効である。このため、本発明の各実施形態では、特定の波長域（２００～２３０ｎｍ）の紫外線を使用する。 As an example, when a conventional 254 nm sterilization lamp (ultraviolet wavelength peak 254 nm) was used, methicillin-resistant Staphylococcus aureus (MRSA type USA300) was compared with the killing of AG1522 standard human fibroblasts. Die at a high level. However, similar data using a 207 nm excimer lamp show that even with increased UV irradiation, human fibroblast mortality is kept lower than with MRSA. From this, ultraviolet rays in a specific wavelength range (200 to 230 nm) are effective in killing MRSA. Therefore, in each embodiment of the present invention, ultraviolet rays in a specific wavelength range (200 to 230 nm) are used.
＜反射部７，８＞
　反射部７，８を設ける場合、図４と図２に示すようには、装着部２において反対側にそれぞれ配置されている。一方の反射部７は、一方の紫外線発生部５に対向して配置され、他方の反射部８は、他方の紫外線発生部５に対向して配置されている。一方の反射部７は、一方の紫外線発生部５の複数の光源１１の配列に対応して装着部２の外周面近くに、円周方向に円弧形状に凹面形状で所定の長さと幅で形成されている。同様にして、他方の反射部８は、他方の複数の紫外線発生部５の光源１１の配列に対応して装着部２の外周面近くに、円周方向に円弧形状に凹面形状で所定の長さと幅で形成されている。反射部７の位置は、手の表５１７に対応し、反射部８の位置は、手の裏５１８に対応している。 < Reflective parts 7, 8>

One reflecting unit 7 is arranged so as to face one ultraviolet light generating unit 5, and the other reflecting unit 8 is arranged so as to face the other ultraviolet light generating unit 5. One reflecting portion 7 is formed in a concave shape in an arc shape in the circumferential direction and having a predetermined length and width near the outer peripheral surface of the mounting portion 2 corresponding to the arrangement of the plurality of light sources 11 of the one ultraviolet generating portion 5. Has been done. Similarly, the other reflecting portion 8 has a predetermined length in a concave shape in an arc shape in the circumferential direction near the outer peripheral surface of the mounting portion 2 corresponding to the arrangement of the light sources 11 of the other plurality of ultraviolet generating portions 5.

The position of the reflective portion 7 corresponds to the front surface 517 of the hand, and the position of the reflective portion 8 corresponds to the back 518 of the hand.

The reflecting units 7 and 8 reflect a specific ultraviolet wavelength range (200 to 230 nm) generated by the plurality of light sources 11 of one ultraviolet generating unit 5 and the plurality of light sources 11 of the other ultraviolet generating unit 5, respectively. , Irradiates a specific ultraviolet wavelength range over the entire finger (whole area).
＜携帯型紫外線殺菌装置１の使用例＞
　次に、携帯型紫外線殺菌装置１を使用して、手指５０１の殺菌を行う使用例を説明する。
　図１と図３に示すように、装着部２は、手指５０１側から装着部２の開口部３に通すことで、前腕５００に着脱可能に装着できる。装着部２がリング状であっても、装着部２は、好ましくは密着部分２Ｂを有しているので、装着部２は、密着部分２Ｂにより前腕５００の外周面に密着した状態で回転しないように保持できる。使用者が図１と図３に示すスイッチ１０を押すと、図３に示す制御部６が紫外線発生部５を駆動して、紫外線発生部５，５の各光源１１は、特定の波長域（２００～２３０ｎｍ）の紫外線を照射させる。 <Usage example of portable UV sterilizer 1>
Next, an example of using the portable ultraviolet sterilizer 1 to sterilize the fingers 501 will be described.
As shown in FIGS. 1 and 3, the mounting portion 2 can be detachably mounted on the forearm 500 by passing it through the opening 3 of the mounting portion 2 from the finger 501 side. Even if the mounting portion 2 has a ring shape, the mounting portion 2 preferably has a close contact portion 2B, so that the mounting portion 2 does not rotate in a state of being in close contact with the outer peripheral surface of the forearm 500 by the close contact portion 2B. Can be held in. When the user presses the switch 10 shown in FIGS. 1 and 3, the control unit 6 shown in FIG. 3 drives the ultraviolet light generating unit 5, and each light source 11 of the ultraviolet light generating units 5 and 5 has a specific wavelength range ( Irradiate with ultraviolet rays (200 to 230 nm).
　図４に例示するように、反射部７，８は、一方の紫外線発生部５の複数の光源１１と他方の紫外線発生部５の複数の光源１１がそれぞれ発生する特定の波長域の紫外線を反射する。このため、特定の波長域の紫外線は、手指の全体に渡って照射する。すなわち、特定の波長域の紫外線は、矢印Ｒで例示するように、主に菌の伝播に関係する部位である、手指５０１の親指５１１、人差し指５１２、中指５１３、薬指５１４、小指５１５、母指球５１６、手の表（手の甲）５１７、手の裏（手の平）５１８、特に手指の先端（爪と指の間）にまんべんなく照射される。これにより、手指５０１の全体が、特定の波長域の紫外線により照射されるので、手指５０１の全体を殺菌できる。 As illustrated in FIG. 4, the reflecting units 7 and 8 reflect ultraviolet rays in a specific wavelength range generated by the plurality of light sources 11 of one ultraviolet generating unit 5 and the plurality of light sources 11 of the other ultraviolet generating unit 5, respectively. To do. Therefore, ultraviolet rays in a specific wavelength range are applied over the entire finger. That is, as illustrated by the arrow R, the ultraviolet rays in a specific wavelength range are the parts mainly related to the transmission of bacteria, the thumb 511 of the finger 501, the index finger 512, the middle finger 513, the ring finger 514, the little finger 515, and the mother finger. The ball 516, the front surface (back of the hand) 517, the back of the hand (palm) 518, especially the tips of the fingers (between the thumbs) are evenly irradiated. As a result, the entire hand 501 is irradiated with ultraviolet rays in a specific wavelength range, so that the entire finger 501 can be sterilized.
　図５は、携帯型紫外線殺菌装置１を使用して、手指５０１の殺菌を行っている様子を示している。図５（Ａ）に示す例では、手の表５１７と手の裏５１８がまっすぐ伸びている状態を示し、図５（Ｂ）に示す例では、手の裏５１８が折り曲げられており、手の表５１７が山形になっている状態を示している。いずれに示す状態であっても、特定の波長域の紫外線は、矢印Ｒで例示するように、手指５０１の全体にわたって照射して殺菌することができる。 FIG. 5 shows how the portable ultraviolet sterilizer 1 is used to sterilize the fingers 501. In the example shown in FIG. 5 (A), the front surface 517 of the hand and the back surface 518 of the hand are shown to be straight, and in the example shown in FIG. 5 (B), the back surface 518 of the hand is bent and the front surface 517 of the hand is chevron. Indicates the state of. In any of the states, ultraviolet rays in a specific wavelength range can be sterilized by irradiating the entire finger 501 as illustrated by the arrow R.
　図６は、左手ＬＨと右手ＲＨを近づけている状態を示している。左手ＬＨと右手ＲＨの各前腕５００には、それぞれ携帯型紫外線殺菌装置１が装着されている。この状態では、左手ＬＨの携帯型紫外線殺菌装置１から照射される矢印Ｒで示す特定の波長域の紫外線が左手ＬＨだけに照射されるのではなく、右手ＲＨ側にも照射できる。同様にして、右手ＲＨの携帯型紫外線殺菌装置１から照射される矢印Ｒで示す特定の波長域の紫外線は、右手ＲＨだけに照射されるのではなく、左手ＬＨ側にも照射できる。これにより、医療従事者や患者等の使用者は、時々両手を近づけるだけで、特に意識することなく、よりまんべんなく両手の全体を殺菌できる。 FIG. 6 shows a state in which the left hand LH and the right hand RH are brought close to each other. A portable ultraviolet sterilizer 1 is attached to each of the forearms 500 of the left hand LH and the right hand RH. In this state, the ultraviolet rays in the specific wavelength range indicated by the arrow R emitted from the portable ultraviolet sterilizer 1 of the left hand LH can be applied not only to the left hand LH but also to the right hand RH side. Similarly, the ultraviolet rays in the specific wavelength range indicated by the arrow R emitted from the portable ultraviolet sterilizer 1 of the right hand RH can be applied not only to the right hand RH but also to the left hand LH side. As a result, users such as medical staff and patients can sterilize the entire hands more evenly without being particularly conscious by simply bringing their hands close to each other from time to time.
　このように、携帯型紫外線殺菌装置１は、前腕５００に装着するだけで、使用者の手指の全体に対して、人体へのダメージの無い短波長の紫外線（ＵＶ－Ｃ）を照射することで、手指の全体を自動的に殺菌できる。携帯型紫外線殺菌装置１は、適切な短波長の紫外線の照射時間、タイミング、角度で自動照射され、装着しているだけで、手指の全体の殺菌状態を適切に保ち、例えば院内感染の発生率を低減できる。これにより、薬剤耐性菌（ＭＲＳＡ）等の院内感染に伴う患者や医療従事者の感染を防ぎ、医療費の削減が図れる。 In this way, the portable ultraviolet sterilizer 1 is simply attached to the forearm 500 to irradiate the entire fingers of the user with short-wavelength ultraviolet rays (UV-C) that do not damage the human body. , The entire finger can be sterilized automatically. The portable ultraviolet sterilizer 1 is automatically irradiated with an appropriate short wavelength ultraviolet irradiation time, timing, and angle, and simply by wearing it, it keeps the entire sterilized state of the fingers properly, for example, the incidence of nosocomial infections. Can be reduced. As a result, infections of patients and medical staff due to nosocomial infections such as drug-resistant bacteria (MRSA) can be prevented, and medical expenses can be reduced.
　次に、本発明の第２実施形態と第３実施形態を、順次説明する。第２実施形態と第３実施形態における構成要素が、上述した第１実施形態の構成要素と実質的に同等である場合には、同じ符号を記してその説明を用いることにする。
（第2実施形態）
　次に、本発明の第２実施形態の携帯型紫外線殺菌装置１０１を、図７と図８を参照して説明する。図７は、本発明の第２実施形態の携帯型紫外線殺菌装置１０１を示す正面図である。図８は、図７に示す携帯型紫外線殺菌装置１０１により手指５０１を殺菌している様子を示している。 Next, the second embodiment and the third embodiment of the present invention will be described in sequence. When the components of the second embodiment and the third embodiment are substantially equivalent to the components of the first embodiment described above, the same reference numerals are given and the description thereof will be used.
(Second Embodiment)
Next, the portable ultraviolet sterilizer 101 of the second embodiment of the present invention will be described with reference to FIGS. 7 and 8. FIG. 7 is a front view showing the portable ultraviolet sterilizer 101 of the second embodiment of the present invention. FIG. 8 shows a state in which the fingers 501 are sterilized by the portable ultraviolet sterilizer 101 shown in FIG.
　図７と図８に示す携帯型紫外線殺菌装置１０１が、前腕５００に装着するリング状の装着部１０２と、電源部１０４と、装着部１０２の内周面から所定離間して設けられた紫外線発生部１０５，１０５と、センサ９と、導光部１５０，１５０と、制御部１０６と、装着部１０２の外周面近くに、円周方向に円弧形状に凹面形状で所定の長さと幅で形成された反射部１０７，１０８を備える。電源部１０４と紫外線発生部１０５，１０５とセンサ９と導光部１５０，１５０と反射部１０７，１０８は、装着部１０２に配置されている。この携帯型紫外線殺菌装置１０１が、図１から図４に示す携帯型紫外線殺菌装置１と異なる点を、次に説明する。紫外線発生部１０５，１０５を覆うように、光拡散部（不図示）を設けてもよい。この光拡散部としては、エンボス加工などで微細な凹凸を形成したポリカーボネート樹脂、両凸レンズ状で大きさ（平均粒径１０μｍ程度）に形成した架橋ポリメタクリル酸メチルを塗布することで得られる。 The portable ultraviolet sterilizer 101 shown in FIGS. 7 and 8 is provided with a ring-shaped mounting portion 102 mounted on the forearm 500, a power supply portion 104, and an ultraviolet generating portion 102 provided at a predetermined distance from the inner peripheral surface of the mounting portion 102. Parts 105, 105, sensors 9, light guide parts 150, 150, control parts 106, and mounting parts 102 are formed in a concave shape in an arc shape in the circumferential direction with a predetermined length and width near the outer peripheral surface. The reflecting portions 107 and 108 are provided. The power supply unit 104, the ultraviolet light generating unit 105, 105, the sensor 9, the light guide unit 150, 150, and the reflecting unit 107, 108 are arranged in the mounting unit 102. The difference between the portable ultraviolet sterilizer 101 and the portable ultraviolet sterilizer 1 shown in FIGS. 1 to 4 will be described below. A light diffusing part (not shown) may be provided so as to cover the ultraviolet light generating parts 105 and 105. The light diffusing portion can be obtained by applying a polycarbonate resin having fine irregularities formed by embossing or the like, or a crosslinked polymethyl methacrylate formed into a biconvex lens shape (average particle size of about 10 μm).
　すなわち、紫外線発生部１０５，１０５は、ともに１つの光源により構成され、この光源が発生する紫外線の波長としては、短波長の特定の波長域の紫外線（ＵＶ－Ｃ）である１００～２８０ｎｍの波長域の内の一部の特定の波長域である２００～２３０ｎｍを採用している。導光部１５０，１５０は、紫外線発生部１０５，１０５にそれぞれ対応して配置されているレンズである。 That is, the ultraviolet generation units 105 and 105 are both composed of one light source, and the wavelength of the ultraviolet rays generated by this light source is a wavelength of 100 to 280 nm, which is an ultraviolet ray (UV-C) in a specific wavelength range having a short wavelength. 200 to 230 nm, which is a specific wavelength range of a part of the range, is adopted. The light guide units 150 and 150 are lenses arranged corresponding to the ultraviolet light generating units 105 and 105, respectively.
　図８に例示するように、一方の導光部１５０は、一方の紫外線発生部１０５からの特定の波長域の紫外線を、一方の反射部１０７に導く。同様にして、他方の導光部１５０は、他方の紫外線発生部１０５からの特定の波長域の紫外線を、他方の反射部１０８に導く。一方の反射部１０７と他方の反射部１０８は、ともに図８に例示するように矢印Ｒで示すように、特定の波長域の紫外線を反射する。このため、特定の波長域の紫外線は、手指の先端（爪と指の間）を含めた手指の全体に渡って照射される。これにより、手指５０１の全体が、特定の波長域の紫外線の照射により、殺菌できる。 As illustrated in FIG. 8, one light guide unit 150 guides ultraviolet rays in a specific wavelength range from one ultraviolet light generating unit 105 to one reflecting unit 107. Similarly, the other light guide unit 150 guides ultraviolet rays in a specific wavelength range from the other ultraviolet light generating unit 105 to the other reflecting unit 108. Both the one reflecting portion 107 and the other reflecting portion 108 reflect ultraviolet rays in a specific wavelength range as shown by an arrow R as illustrated in FIG. Therefore, ultraviolet rays in a specific wavelength range are irradiated over the entire finger including the tip of the finger (between the nail and the finger). As a result, the entire hand 501 can be sterilized by irradiation with ultraviolet rays in a specific wavelength range.
（第３実施形態）
　次に、本発明の第３実施形態の携帯型紫外線殺菌装置２０１を、図９と図１０を参照して説明する。図９は、本発明の第３実施形態の携帯型紫外線殺菌装置２０１を示す図である。図１０は、図９に示す携帯型紫外線殺菌装置２０１により手指５０１を殺菌している様子を示している。
　図９と図１０に示す携帯型紫外線殺菌装置２０１が、前腕５００に装着するリング状の装着部２０２と、電源部２０４と、１つの紫外線発生部２０５と、センサ９と、１つのリング状の導光部２５０と、制御部２０６と、２つの光拡散部２０７，２０８を備える。電源部２０４と１つの紫外線発生部２０５とセンサ９と１つの導光部２５０と２つの光拡散部２０７，２０８は、装着部２０２に配置されている。この携帯型紫外線殺菌装置２０１が、図１から図４に示す携帯型紫外線殺菌装置１と異なる点を、次に説明する。 (Third Embodiment)
Next, the portable ultraviolet sterilizer 201 of the third embodiment of the present invention will be described with reference to FIGS. 9 and 10. FIG. 9 is a diagram showing a portable ultraviolet sterilizer 201 according to a third embodiment of the present invention. FIG. 10 shows a state in which the fingers 501 are sterilized by the portable ultraviolet sterilizer 201 shown in FIG.
The portable ultraviolet sterilizer 201 shown in FIGS. 9 and 10 has a ring-shaped mounting portion 202, a power supply portion 204, one ultraviolet generating portion 205, a sensor 9, and one ring-shaped mounting portion 202 mounted on the forearm 500. It includes a light guide unit 250, a control unit 206, and two light diffusion units 207 and 208. The power supply unit 204, one ultraviolet light generating unit 205, the sensor 9, one light guide unit 250, and two light diffusing units 207 and 208 are arranged in the mounting unit 202. The difference between the portable ultraviolet sterilizer 201 and the portable ultraviolet sterilizer 1 shown in FIGS. 1 to 4 will be described below.
　図９（Ａ）に示すように、紫外線発生部２０５は、１つの光源であり、この光源が発生する紫外線の波長としては、短波長の特定の波長域の紫外線（ＵＶ－Ｃ）である１００～２８０ｎｍの波長域の内の一部の特定の波長域である２００～２３０ｎｍを採用している。１つの導光部２５０としては、１本の光ファイバを用いていて、この導光部２５０は装着部２０２のリング形状に沿ってリング状に配置されている。導光部２５０の２つの入射端部２５１，２５２は、紫外線発生部２０５に対応して配置されている。導光部２５０は、図９（Ｂ）に示すように、コア２５５と、例えばアルミニウム薄膜で形成されたクラッド２５６を有し、紫外線発生部２０５からの紫外線は、矢印Ｓで示すように、コア２５５内において導かれながらクラッド２５６の内壁面で反射して進む。クラッド２５６には、所定間隔ごとに複数の開口部２８０が形成されている。 As shown in FIG. 9A, the ultraviolet generation unit 205 is one light source, and the wavelength of the ultraviolet rays generated by this light source is 100, which is an ultraviolet ray (UV—C) in a specific wavelength range having a short wavelength. 200 to 230 nm, which is a specific wavelength range of a part of the wavelength range of to 280 nm, is adopted. One optical fiber is used as one light guide unit 250, and the light guide unit 250 is arranged in a ring shape along the ring shape of the mounting unit 202. The two incident end portions 251,252 of the light guide portion 250 are arranged so as to correspond to the ultraviolet ray generating portion 205. As shown in FIG. 9B, the light guide unit 250 has a core 255 and a clad 256 formed of, for example, an aluminum thin film, and the ultraviolet rays from the ultraviolet light generating unit 205 are the cores as shown by arrows S. While being guided in 255, it reflects on the inner wall surface of the clad 256 and proceeds. A plurality of openings 280 are formed in the clad 256 at predetermined intervals.
　これらの開口部２８０は、光拡散部２０７，２０８にそれぞれ対面した位置に形成されている。これらの開口部２８０では、コア２５５が露出されていることから、コア２５５を通る紫外線は、矢印Ｔで示すように、コア２５５から開口部２８０を通ってクラッド２５６の外へ導かれる。クラッド２５６の外に導かれた紫外線は、矢印Ｒで示すように光拡散部２０７，２０８により拡散されて、図１０に例示する矢印Ｒで示すように、特定の波長域の紫外線が照射される。このため、特定の波長域の紫外線は、手指の全体に渡って照射される。これにより、手指の先端（爪と指の間）を含めた手指５０１の全体が、光拡散部２０７，２０８を経た特定の波長域の紫外線により照射されることから、殺菌できる。光拡散部２０７，２０８は、エンボス加工などで微細な凹凸を形成したポリカーボネート樹脂、両凸レンズ状で大きさ（平均粒径１０μｍ程度）に形成した架橋ポリメタクリル酸メチルを塗布することで得られる。また、上述の光拡散部を開口部２８０に設けてもよい。 These openings 280 are formed at positions facing the light diffusing portions 207 and 208, respectively. Since the core 255 is exposed in these openings 280, ultraviolet rays passing through the core 255 are guided from the core 255 through the opening 280 to the outside of the clad 256 as shown by an arrow T. The ultraviolet rays guided to the outside of the clad 256 are diffused by the light diffusing portions 207 and 208 as shown by arrows R, and are irradiated with ultraviolet rays in a specific wavelength range as shown by arrows R illustrated in FIG. .. Therefore, ultraviolet rays in a specific wavelength range are irradiated over the entire finger. As a result, the entire finger 501 including the tip of the finger (between the nail and the finger) is irradiated with ultraviolet rays in a specific wavelength range passing through the light diffusing portions 207 and 208, so that the finger can be sterilized. The light diffusing portions 207 and 208 are obtained by applying a polycarbonate resin having fine irregularities formed by embossing or the like, and crosslinked polymethyl methacrylate formed into a biconvex lens shape (average particle size of about 10 μm). Further, the above-mentioned light diffusing portion may be provided in the opening 280.

　図１３に示す本発明の実施形態の携帯型紫外線殺菌装置６０１では、装着部６０２がC字型に形成されている。このため、装着部６０２の一端部と他端部により形成される隙間部分６０３には、前腕５００を挿入することで、装着部６０２は２点鎖線で示すように弾性変形する。これにより、前腕５００は、より簡単に装着部６０２の開口部３内に入れることで、携帯型紫外線殺菌装置６０１が前腕５００に装着できる。携帯型紫外線殺菌装置６０１を前腕５００に確実に装着するために、隙間部分６０３を固定するための係合部、例えば面ファスナを、装着部６０２の隙間部分６０３を形成する近傍の適所に延設するなどして設けてもよい。隙間部分６０３を大きく形成すると前腕５００を挿入することが極めて容易になる。 (Other embodiments)
