【発明の属する技術分野】
本発明は、特に病院医療施設や老人介護施設等で発生する臭気を速やかに脱臭し、脱臭後に清浄空気を室内に戻せるようにした医療・介護用脱臭装置に関する。
【0002】
【従来の技術】
病院医療施設や老人介護施設等においては、汚物や排泄物等の臭気が室内に漂うことが多い。このような室内で発生する臭気を除去するには、従来例えば換気扇や空気清浄器等を用いて排出するとか、活性炭等の吸着材や消臭剤等を用いて消臭する等の手段が採られている。
【0003】
最近では光触媒の抗菌機能、脱臭機能に注目して、例えば珪藻土からなる吸着材料と光触媒とを混合して建築材料或は塗料とし、その建築材料又は塗料を建築物の内部に施工し、タバコ臭、糞尿臭のような悪臭を短時間で効率的に、しかも経済的且つ半永久的に脱臭することにより、病院医療施設や老人介護施設等で発生する臭気を脱臭するようにした、消臭材料及び消臭方法が開示されている(特許文献1)。
【0004】
又、空調機、冷蔵庫、調理機、乾燥機等の機器分野において、悪臭や揮発性有害物質を除去するために、光触媒と紫外線照射ランプを用いた脱臭浄化装置が開示されている(例えば、特許文献2)。この脱臭浄化装置では、光触媒として酸化チタン薄膜を用いて、二種類の径の異なる管並びに紫外線を放出するランプの内外壁に酸化チタンを形成し、このランプと酸化チタン膜並びに酸化チタンを形成した管を同心円状に配置することで、ランプから放出される光エネルギーを効率的に利用することが可能となり、取り扱いや脱臭浄化効率に優れたものとしている。
【0005】
更に、室内で発生する汚染空気を浄化するための装置としては、例えば室内からの空気を吸引するファンの下流に、室内の外部までの換気流路と室内に戻る還流路とをそれぞれ接続し、換気流路と環流路の分岐部にそれぞれの流路の開度を変更可能なダンパを配置し、このダンパの下流の環流路に空気の浮遊塵埃を捕捉する中性能フィルタと臭気を脱臭する光触媒脱臭ユニットを備えた換気装置が開示されている(特許文献3)。

【発明が解決しようとする課題】
上記従来技術において、光触媒を含む材料で形成した建築材料や塗料を用いるもの、又は光触媒と紫外線照射ランプを用いた脱臭浄化機能を有する空調機を用いるもの、或は光触媒脱臭ユニットを備えた換気装置を用いるものは、いずれも室内全体の消臭を目的としたものである。しかしながら、病院医療施設等では、例えば手術室で電気メスにより体の患部を切除することにより生じる臭気や内臓の臭気等が問題になっている。又、老人介護施設等では、寝たきり老人のオムツ替え時に排泄物のにおいが室内に拡散して、悪臭が問題になっている。このように室内の一部で発生する悪臭を、上記従来のような手段で速やかに消臭することはできない。
【0008】
手術時に発生する臭気に関しては、具体的な消臭対策が何ら施されておらず、執刀医らは業務上当然のこととして受け止め、マスクで防御しているのが現状である。又、寝たきり老人のオムツ替え時に発生する悪臭に関しては、局所的に排気する設計例もごく少数見受けられるが、換気装置や消臭装置等の機器がベッドから離れた位置に配置されている場合には十分な消臭効果が挙げられず、排気経路に至るまでに臭気が室内に拡散してしまうという問題があった。
【0009】
本発明者らは、上記の事態を解消すべく鋭意研究した結果、例えば手術台やベッドの直近に消臭装置を配置し、好ましくは手術台やベッドに消臭装置を組み込むことにより局所で発生する臭気を速やかに消臭できることを見出して本発明を完成するに至った。即ち、本発明は、手術台やストレッチャー、ベッド等の直近から臭気を吸い込み、酸化チタン系の光触媒により脱臭し、清浄空気を室内に戻せるようにした医療・介護用脱臭装置を提供することを目的とする。
【0010】
【課題を解決するための手段】
上記の目的を達成するための手段として、請求項1の発明は、手術台、ストレッチャー、ベッド等の台部近傍に設けた臭気吸込口と、この臭気吸込口から吸い込んだ臭気を、光触媒部材とこの光触媒部材に光線を照射する光源ランプとを有する脱臭部に導入する導入路と、前記脱臭部で脱臭した清浄空気を室内に導出する導出路と、この導出路の内部に設けた送風機とを具備してなることを特徴とする医療・介護用脱臭装置である。
【0011】
この請求項1の構成により、手術台等の局所で発生する臭気を直ちに吸い込んで室内に拡散するのを防止することができる。又、吸い込んだ臭気を脱臭部にて光触媒により脱臭し、脱臭後の清浄空気を室内に戻すことができる。
【0012】
又、請求項2の発明は、請求項1記載の医療・介護用脱臭装置において、前記導入路の一部に、台部上の局所で発生する臭気を吸い込む分岐ホースを接続したことを特徴とするものである。
【0013】
この請求項2の構成により、分岐ホースを用いて台部上の局所で発生する臭気を効率良く吸い込むことができる。
【0014】
【発明の実施の形態】
次に、本発明に係る医療・介護用脱臭装置の一実施形態を添付図面に基づいて説明する。図1は、本発明に係る医療・介護用脱臭装置の実施形態を模式的に示す概略図である。尚、本発明は、この実施形態のものに限定されるものではない。
【0015】
図1において、1は手術台、ストレッチャー、ベッド等の台部であり、その近傍に脱臭装置2が組み込まれている。3は臭気吸込口であり、台部1の上面外周部に沿って台部1を取り囲むようにして設けられている。この臭気吸込口3は、これに限定されずに例えば台部1の両側部等適宜の部位に設けるようにしてもよい。又、臭気吸込口3には、細網状又は小格子状のカバー3aを着脱可能に装着すると、小物類の落下防止となって好ましい。
【0016】
4は臭気吸込口3から吸い込んだ臭気を脱臭部5に導入するための導入路である。この導入路4は、臭気吸込口3が上記のように台部1の外周部に沿って取り囲むように設けられている場合には、その全周の臭気吸込口3が脱臭部5の入口5aに連通する部屋状体として、台部1の下方に設けることが好ましい。又、臭気吸込口3が台部1の外周部における適宜の部位に設けられている場合には、その臭気吸込口3と脱臭部5の入口5aとを連結する管状体として設け、或は臭気吸込口3が2箇所以上に分設されている場合には、導入路となる複数の管状体を途中で合流させて脱臭部5の入口5aに接続するようにすればよい。
【0017】
前記脱臭部5は、所定の容積を備えた部屋状体に形成され、この部屋状体の内部に光触媒部材6と光源ランプ7とが配設されている。光触媒部材6は、例えばガラス板の表面に光触媒を塗布してなるもので、光触媒塗布面6aが脱臭部5の入口5a側に向くようにして、入口5aの下方にほぼ水平に位置させて配置する。光触媒としては、酸化チタン系の例えば二酸化チタン(TiO)を使用することができる。
【0018】
上記光源ランプ7は、光触媒部材6の光触媒塗布面6aに対向するようにして脱臭部5の上壁部に複数個並列に配設し、これらの光源ランプ7により光触媒塗布面6aの光触媒を照射する。光源ランプ7としては、紫外線を放射するランプ(水銀ランプ、キセノンランプ等)が好ましいが、この場合は蛍光灯が用いられている。蛍光灯の光線にも紫外線が含まれているため光触媒を励起させることができる。白熱電球の光線には紫外線は含まれていないので適用できない。蛍光灯は安価に入手できて、手軽に交換できること等から使用に適している。
【0019】
上記脱臭部5の下部には、複数の導出路8が脱臭部5に連通して設けられ、導出路8の内部には送風機9がそれぞれ設けられ、各導出路8の先端は室内に開口している。
【0020】
前記導入路4の一部には、臭気吸込用の分岐ホース10が接続して設けられている。この分岐ホース10は、フレキシブルに形成されたホースであって基端部が導入路4に連結され、先端部には吸入口10aを有しており、その吸入口10aが台部1のほぼ上面全域に届くに足る長さを備えている。又、分岐ホース10を着脱できるように、例えば導入路4側に取付口(図略)を設け、この取付口に分岐ホース10の基端部に設けた接続口10bを挿脱可能に構成してもよい。
【0021】
更に、台部1が移動式のストレッチャーの場合には、小型の電源装置(図略)を搭載して前記光源ランプ7及び送風機9に電力を供給するように構成することも可能である。
【0022】
上記のように構成された本実施形態での医療・介護用脱臭装置の使用状態について説明する。例えば、病院医療施設等での手術時又は老人介護施設等でのオムツ替え時において、前記光源ランプ7を点灯すると共に、送風機9を回転させる。
【0023】
上記送風機9の回転により導入路4側に吸込力が生じ、これにより台部1上で局所的に発生した臭気は、臭気吸込口3から導入路4内に吸引される。臭気吸込口3は台部1に近接しているため、台部1上で局所的に発生した臭気を速やかに吸引して室内に臭気が拡散するのを阻止することができる。この際、前記分岐ホース10の吸入口10aを臭気発生源に近付けることにより臭気を直ちに吸引して、臭気の拡散をより一層確実に阻止することが可能となる。
【0024】
導入路4内に吸引された臭気は、送風機9による吸込力によって脱臭部5内に導入される。脱臭部5の入口5aから導入された臭気は、放射方向に分流されて光触媒部材6の光触媒塗布面6aに沿って流れる。
【0025】
光触媒部材6の光触媒塗布面6aでは、光源ランプ7からの照射光線により光触媒が励起されて活性化状態になっており、光触媒塗布面6aに沿って流れる臭気中の分子を吸着して酸化力の強い原子状酸素により酸化する。この光触媒反応(光酸化反応)によって臭気成分は分解されて脱臭される。又、臭気中に細菌が含まれている場合には、その表面が光触媒によって分解されるので死滅する。従って、光触媒により脱臭、殺菌が行われる。光触媒による光触媒反応では、COの吸着が弱いので被毒は起こらず、触媒活性が持続して半永久的に使用できる。
【0026】
脱臭部5内での脱臭、殺菌により清浄化された清浄空気は、送風機9により導出路8を経て室内に排出される。
【0027】
尚、上記実施形態の構成に限定されずに、例えば図示は省略したが導入路4の内部に吸引用のファンを設けて吸引力を増大させる、制御装置により送風機9の回転を制御して脱臭部5内を流通する臭気の流速を調整し、或は室内に排出する清浄空気の流速や排出量を調整する、等の構成を加えて実施することが可能である。又、光触媒部材6の前(上流側)に活性炭等の吸着剤を設置し、一時的に臭気をトラップさせ、処理するシステムも可能である。
【0028】
【発明の効果】
以上説明したように、本発明に係る請求項1の医療・介護用脱臭装置によれば、手術台、ストレッチャー、ベッド等の局所で発生する臭気を直ちに吸い込んで室内に拡散するのを防止することができる。従って、病院医療施設では、手術時に発生する臭気を医師の鼻に至る前に吸収して脱臭することができ、老人介護施設では、ベッド上での排泄物の悪臭をその場で消臭して他所に拡散させない効果が得られる。又、吸い込んだ臭気を脱臭部にて光触媒により脱臭し、脱臭後の清浄空気を室内に戻すことができる。これにより、ウィルスや細菌等の感染性疾患の患者に適用した場合には、医師、看護士等への二次感染や室内感染をも防止することができる。
更に、光触媒を利用しているので、光源ランプを交換することだけで脱臭効果を半永久的に持続でき、活性炭のように取り替える必要がなく、二次的汚染や廃棄物処理問題もない。
【0029】
又、本発明に係る請求項2の医療・介護用脱臭装置によれば、分岐ホースを用いて台部上の局所で発生する臭気をより一層効率良く吸い込むことができ、且つ医師や看護士又は介護士等が簡単に使用することができる。

However, in hospital medical facilities and the like, for example, the odor produced by excising the affected part of the body with an electric scalpel in the operating room, the odor of the internal organs, and the like are problematic. In elderly care facilities, the smell of excrement diffuses into the room when bedridden elderly people change diapers, and bad odor is a problem. Thus, the bad odor generated in a part of the room cannot be quickly deodorized by the conventional means.
[0008]
No specific deodorization measures have been taken for the odor generated during the operation, and the surgeons take it as a matter of course and protect it with a mask. In addition, regarding odors that occur when changing the diaper of a bedridden elderly person, there are very few examples of local exhaust design, but when equipment such as a ventilator or deodorizer is located away from the bed Does not have a sufficient deodorizing effect, and there is a problem that odors diffuse into the room before reaching the exhaust path.
[0009]
As a result of diligent research to solve the above situation, the present inventors have arranged a deodorizing device in the immediate vicinity of, for example, an operating table or bed, and preferably generated locally by incorporating the deodorizing device into the operating table or bed. The present invention has been completed by finding that the odor can be quickly removed. That is, the present invention provides a deodorizing apparatus for medical / nursing care in which odors are sucked from the immediate vicinity of an operating table, stretcher, bed, etc., deodorized by a titanium oxide photocatalyst, and clean air can be returned to the room.

[0014]
DETAILED DESCRIPTION OF THE INVENTION
Next, one embodiment of a medical / care deodorizing apparatus according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic view schematically showing an embodiment of a medical / nursing care deodorizing apparatus according to the present invention. The present invention is not limited to this embodiment.
[0015]
In FIG. 1, reference numeral 1 denotes a table such as an operating table, stretcher, bed, etc., and a deodorizing device 2 is incorporated in the vicinity thereof. Reference numeral 3 denotes an odor suction port, which is provided so as to surround the base portion 1 along the upper surface outer peripheral portion of the base portion 1. The odor suction port 3 is not limited to this, and may be provided at an appropriate portion such as both side portions of the base 1. In addition, it is preferable to attach a reticulated or small lattice-like cover 3a to the odor suction port 3 so as to prevent small items from falling.
[0016]
Reference numeral 4 denotes an introduction path for introducing the odor sucked from the odor suction port 3 into the deodorization unit 5. When the odor suction port 3 is provided so as to surround the outer peripheral portion of the base portion 1 as described above, the odor suction port 3 is provided at the inlet 5a of the deodorization portion 5 when the odor suction port 3 is provided. It is preferable to provide the room-like body that communicates with the base 1 below the base 1. When the odor suction port 3 is provided at an appropriate position on the outer peripheral portion of the base portion 1, it is provided as a tubular body connecting the odor suction port 3 and the inlet 5a of the deodorization unit 5, or the odor In the case where the suction ports 3 are provided at two or more locations, a plurality of tubular bodies serving as introduction paths may be joined together and connected to the inlet 5a of the deodorizing unit 5.
[0017]
The deodorizing unit 5 is formed in a room-like body having a predetermined volume, and a photocatalyst member 6 and a light source lamp 7 are disposed inside the room-like body. The photocatalyst member 6 is formed, for example, by applying a photocatalyst to the surface of a glass plate, and is disposed so as to be positioned substantially horizontally below the inlet 5a so that the photocatalyst application surface 6a faces the inlet 5a side of the deodorizing unit 5. To do. As the photocatalyst, titanium oxide-based, for example, titanium dioxide (TiO 2 ) can be used.
[0018]
A plurality of the light source lamps 7 are arranged in parallel on the upper wall portion of the deodorizing portion 5 so as to face the photocatalyst application surface 6a of the photocatalyst member 6, and the light catalyst 7 irradiates the photocatalyst on the photocatalyst application surface 6a. To do. As the light source lamp 7, a lamp that emits ultraviolet rays (mercury lamp, xenon lamp, etc.) is preferable. In this case, a fluorescent lamp is used. Since the fluorescent light also contains ultraviolet rays, the photocatalyst can be excited. The incandescent light beam is not applicable because it does not contain ultraviolet light. Fluorescent lamps are suitable for use because they are available at low cost and can be easily replaced.
[0019]
A plurality of lead-out paths 8 are provided in communication with the deodorization section 5 at the lower part of the deodorization section 5, and a blower 9 is provided inside the lead-out path 8, and the leading end of each lead-out path 8 opens into the room. ing.
[0020]
A branch hose 10 for sucking odor is connected to a part of the introduction path 4. This branch hose 10 is a hose formed flexibly, and has a base end connected to the introduction path 4 and has a suction port 10 a at the tip, which is substantially the upper surface of the base 1. It is long enough to reach the entire area. Further, for example, an attachment port (not shown) is provided on the introduction path 4 side so that the branch hose 10 can be attached and detached, and the connection port 10b provided at the base end portion of the branch hose 10 can be inserted into and removed from this attachment port. May be.
[0021]
Furthermore, when the base part 1 is a mobile stretcher, it is possible to install a small power supply device (not shown) and supply power to the light source lamp 7 and the blower 9.
[0022]
The use state of the medical / nursing care deodorizing apparatus in the present embodiment configured as described above will be described. For example, the light source lamp 7 is turned on and the blower 9 is rotated during surgery at a hospital medical facility or the like or when changing diapers at an elderly care facility or the like.
[0023]
Due to the rotation of the blower 9, a suction force is generated on the side of the introduction path 4, whereby the odor generated locally on the base 1 is sucked into the introduction path 4 from the odor suction port 3. Since the odor suction port 3 is close to the pedestal 1, the odor generated locally on the pedestal 1 can be quickly sucked to prevent the odor from diffusing into the room. At this time, the odor is immediately sucked by bringing the suction port 10a of the branch hose 10 close to the odor generating source, and the odor diffusion can be more reliably prevented.
[0024]
The odor sucked into the introduction path 4 is introduced into the deodorizing unit 5 by the suction force of the blower 9. The odor introduced from the inlet 5a of the deodorizing unit 5 is diverted in the radial direction and flows along the photocatalyst application surface 6a of the photocatalyst member 6.
[0025]
On the photocatalyst coating surface 6a of the photocatalyst member 6, the photocatalyst is excited and activated by irradiation light from the light source lamp 7, and adsorbs molecules in the odor flowing along the photocatalyst coating surface 6a to generate an oxidizing power. Oxidizes with strong atomic oxygen. Odor components are decomposed and deodorized by this photocatalytic reaction (photooxidation reaction). In addition, when bacteria are included in the odor, the surface is decomposed by the photocatalyst and is killed. Therefore, deodorization and sterilization are performed by the photocatalyst. In the photocatalytic reaction by the photocatalyst, since CO adsorption is weak, poisoning does not occur, and the catalytic activity is sustained and can be used semipermanently.
[0026]
The clean air purified by deodorization and sterilization in the deodorization unit 5 is discharged into the room by the blower 9 through the outlet path 8.
[0027]
It should be noted that the present invention is not limited to the configuration of the above-described embodiment. For example, although not shown, a suction fan is provided in the introduction path 4 to increase the suction power, and the rotation of the blower 9 is controlled by the control device to remove the odor. It is possible to add the configuration such as adjusting the flow rate of the odor flowing through the section 5 or adjusting the flow rate and the discharge amount of the clean air discharged into the room. In addition, a system in which an adsorbent such as activated carbon is installed in front of the photocatalyst member 6 (upstream side), and the odor is temporarily trapped and treated is also possible.
[0028]
【The invention's effect】
As described above, according to the deodorizing apparatus for medical / nursing care according to the first aspect of the present invention, it is possible to prevent a odor generated locally such as an operating table, a stretcher, a bed, etc. from being immediately sucked and diffused into the room. be able to. Therefore, in hospital medical facilities, it is possible to absorb and deodorize the odor generated at the time of surgery before reaching the doctor's nose, and in elderly care facilities, the odor of excrement on the bed is eliminated on the spot. The effect of not diffusing to other places is obtained. Moreover, the inhaled odor can be deodorized by the photocatalyst in the deodorizing section, and the clean air after deodorization can be returned to the room. Thereby, when applied to patients with infectious diseases such as viruses and bacteria, secondary infections and room infections to doctors and nurses can be prevented.
Furthermore, since a photocatalyst is used, the deodorizing effect can be maintained semipermanently only by exchanging the light source lamp, there is no need for replacement like activated carbon, and there is no problem of secondary contamination or waste disposal.
[0029]
Moreover, according to the deodorizing apparatus for medical / nursing care according to claim 2 of the present invention, it is possible to more efficiently inhale the odor generated locally on the pedestal using the branch hose, and a doctor or nurse or Caregivers can use it easily.
