It relates to a rack case for installing a high-frequency generator of a high-frequency thermal cancer treatment device having an improved shielding function to prevent malfunction or failure of a device caused by electromagnetic waves generated during high-frequency generation by the high-frequency generator.
일반적으로 고주파 온열암치료기는 피시술자의 암질환장기가 위치한 피부 위에 고주파전류를 인가하여 발생되는 심부열로 내부의 병변부위를 42도씨 이상으로 국소가열함으로써 암조직을 괴사시키는 비침습 치료장치로서, 방사능 치료나 절개 치료와 비교하여 후유증이나 부작용이 적어 최근 암병원 등에서 치료도구로의 이용이 확산되고 있는 추세이다.In general, a high-frequency thermal cancer treatment device is a non-invasive treatment device that necrotizes cancer tissue by locally heating the lesion area inside to 42 degrees C or higher with deep heat generated by applying a high-frequency current to the skin where the cancer disease organ is located, Compared to radiotherapy or incisional treatment, there are fewer aftereffects or side effects, and recently, cancer hospitals are using it as a treatment tool.

본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of explaining embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as limited to the embodiments described herein.
본 발명에 따른 차폐기능을 갖는 고주파 온열암치료기의 고주파 발생기 설치용 랙케이스는 도 2 내지 도 4에 예시된 바와 같이, 랙케이스본체(10)와, 상기 랙케이스본체(10)에 장입설치된 다수의 고주파 발생기(40)와, 상기 고주파 발생기(40) 사이에 설치되는 다수의 차폐칸막이(30)를 포함한다.As illustrated in Figs. It includes a high frequency generator (40) and a plurality of shielding partitions (30) installed between the high frequency generator (40).
이때, 상기 랙케이스본체(10)는 사각박스 형상으로 형성된다.At this time, the
또한, 상기 차폐칸막이(30)는 상기 고주파 발생기 사이에 설치되어 고주파 발생기에서 발생되는 전자파를 차폐하여 고주파 발생기 상호간 전자파를 차폐함으로써 고주파 발생기(40)가 각각 분리 구획되는 주파챔버를 형성하게 된다.In addition, the
그리고, 상기 랙케이스본체(10)의 일측은 개방되고, 나머지는 밀폐되며, 개방된 부분에는 도어(20)가 설치되어 개폐될 수 있게 구성된다.In addition, one side of the
또한, 상기 랙케이스본체(10)는 스틸로 제조되지만, 전자파(고주파 포함) 차폐 및 절연성능을 확보하기 위해 표면, 즉 내면과 외면 모두에 절연차폐제가 일정두께로 스프레이 코팅된다.In addition, although the
여기에서, 상기 절연차폐제는 폴리카보네이트수지 100중량부에 대해, 그라파이트 파우더(graphite powder) 10중량부, 리그노술폰산나트륨 5중량부, 자성입자가 도핑된 탄소나노튜브 10중량부, 0.1mm 길이를 갖는 전도성 섬유 5중량부, 글리세롤 모노스테아레이트 5중량부, 폴리이미드 3.5중량부를 혼합한 것을 사용한다.Here, the insulating shielding agent is based on 100 parts by weight of polycarbonate resin, 10 parts by weight of graphite powder, 5 parts by weight of sodium lignosulfonate, 10 parts by weight of carbon nanotubes doped with magnetic particles, 0.1 mm in length A mixture of 5 parts by weight of conductive fibers, 5 parts by weight of glycerol monostearate, and 3.5 parts by weight of polyimide is used.
이때, 폴리카보네이트수지는 내오염성, 내식성, 내변형성, 내크랙성 및 내화성과 내열성, 내구성이 뛰어난 베이스 수지이다.At this time, the polycarbonate resin is a base resin excellent in stain resistance, corrosion resistance, deformation resistance, crack resistance, fire resistance, heat resistance, and durability.
그리고, 그라파이트 파우더는 저주파 대역은 물론 고주파 대역 전체에 걸친 차폐효과가 뛰어나 고주파 발생기(40)에서 발진된 고주파가 주파챔버에 갇혀 외부로 발산되는 것을 억제하여 기기의 오동작이나 주변 기기에 영향을 미치는 것이 최소화된다.In addition, the graphite powder has excellent shielding effect over the entire high frequency band as well as the low frequency band, so that the high frequency oscillated by the
아울러, 리그노술폰산나트륨은 음이온계 계면활성제로서 유기물과 무기물의 균일분산성을 촉진하여 고주파 차폐능력을 균일하게 유지하도록 하기 위해 첨가된다.In addition, sodium lignosulfonate is an anionic surfactant, which is added to promote uniform dispersion of organic and inorganic materials to maintain uniform high frequency shielding ability.
또한, 탄소나노튜브는 나노 입도로 분쇄된 물질로서, 전기적 전도 특성을 활용하여 전차파 차폐, 즉 쉴드 능력을 높일 수 있도록 투자율이 높은 물질로 도핑하도록 한다.In addition, carbon nanotubes, which are pulverized into nanoparticles, are doped with a material having high magnetic permeability so as to increase electric wave shielding, that is, shielding ability, by utilizing electrical conduction properties.
그러면, 고주파가 발생될 때 투자율이 높은 도핑물질을 타고 흘러 다른 부분으로 빠지지 않도록 차폐하게 된다.Then, when a high frequency is generated, it flows along the doping material having a high magnetic permeability and is shielded so that it does not fall into another part.
이때, 탄소나노튜브에 도핑되는 자성입자는 페라이트 또는 철계 산화물 중 어느 하나가 될 수 있다. 이 경우, 나노크기 철계 산화물로는 Fe2O3, Fe3O4가 될 수 있다.At this time, the magnetic particles doped into the carbon nanotubes may be either ferrite or iron-based oxide. In this case, the nano-sized iron-based oxide may be Fe 2 O 3 or Fe 3 O 4 .
뿐만 아니라, 전도성 섬유는 탄소섬유 조직 사이로 전도성 필러를 침투시킨 것으로, 섬유에 존재하는 공극을 메워 고주파가 통과할 수 있는 영역에서 고주파를 흡수하여 차폐하는 효과를 높일 수 있다.In addition, the conductive fiber is made by infiltrating the conductive filler between the carbon fiber structures, and it can increase the effect of shielding by absorbing high frequencies in a region through which high frequencies can pass by filling the gaps in the fibers.
이 경우, 상기 전도성 필러는 금속을 이용하여 제조된 전도성 나노입자로서 구리 또는 알루미늄과 같은 금속으로 된 나노입자이다.In this case, the conductive filler is a conductive nanoparticle prepared using a metal and is a nanoparticle made of a metal such as copper or aluminum.
또한, 글리세롤 모노스테아레이트는 대전방지 특성이 매우 뛰어난 물질로서, 전자파는 물론 고주파 차폐 성능까지 갖추고 있다.In addition, glycerol monostearate is a material with very excellent antistatic properties, and has electromagnetic wave as well as high frequency shielding performance.
아울러, 폴리이미드(Poly imide)는 낮은 유전율과 높은 절연성을 제공하면서 유무기물의 바인딩성을 강화시킨다.In addition, polyimide strengthens the binding properties of organic and inorganic materials while providing low permittivity and high insulation.
이에 더하여, 본 발명은 상기 폴리카보네이트수지 100중량부에 대해, 폴리아릴린(polyaniline) 8.5중량부, 스티렌계 엘라스토머 10중량부, 나트륨 메틸실리코네이트(Sodium Methyl Siliconate) 5.5중량부, 사이클로메티콘 5중량부를 더 첨가하여 혼합 사용할 수 있다.In addition, the present invention, based on 100 parts by weight of the polycarbonate resin, polyaniline (polyaniline) 8.5 parts by weight,
이때, 폴리아릴린을 더 첨가하는 이유는 코팅층의 응력과 변형의 비를 낮춰 절연성을 강화시키며, 분산력을 증대시켜 전도성 고분자의 특성을 강화시킴으로써 고주파 차폐력을 증진시키기 위함이다.At this time, the reason why polyaryline is further added is to enhance insulation properties by lowering the ratio of stress and strain of the coating layer, and to improve high-frequency shielding power by enhancing the characteristics of the conductive polymer by increasing the dispersion force.
또한, 스티렌계 엘라스토머는 수소치환된 스티렌-이소프렌 블록 코폴리머(SEPS)를 사용하며, 이는 전기 절연성을 강화시킨다.In addition, the styrenic elastomer uses a hydrogen-substituted styrene-isoprene block copolymer (SEPS), which enhances electrical insulation.
뿐만 아니라, 나트륨 메틸실리코네이트(Sodium Methyl Siliconate)는 강한 발수력을 제공하면서 오염되지 않도록 표면을 평활하게 유지하는 방오 기능도 확보하게 된다.In addition, Sodium Methyl Siliconate provides strong water repellency and also secures an antifouling function that keeps the surface smooth so as not to be contaminated.
그리고, 사이클로메티콘은 산화를 억제하여 표면을 보호하고, 내구성을 강화시킨다.In addition, cyclomethicone inhibits oxidation to protect the surface and enhance durability.

여기에서, ITO(Indium tin oxide) 분말은 전기전도성을 높여 고주파가 표면을 따라 흐르면서 자체 소멸되게 유도하는 특징이 있다.Here, indium tin oxide (ITO) powder has a characteristic of inducing self-dissipation while flowing along the surface by increasing electrical conductivity.
그리고, 폴리에스테르 폴리올은 핫멜팅성을 증가시켜 성형성을 강화시켜 내구성을 확보하고, 메틸렌 디페닐 디이소시아네이트(MDI:Methylene Diphenyl Diisocyanate)는 폴리에스테르 폴리올과 무기물인 파우더와의 상용성을 확보하고 경화를 촉진하여 성형성과 내구성을 강화시킨다.In addition, polyester polyol enhances moldability by increasing hot-melting property to secure durability, and MDI: Methylene Diphenyl Diisocyanate (MDI) secures compatibility between polyester polyol and inorganic powder and promotes curing. It promotes formability and durability.
또한, 디메틸아크릴아마이드는 유동성과 흐름성을 증대시키면서 수축방지를 통해 균열을 억제하는데 기여한다.In addition, dimethylacrylamide contributes to suppressing cracks through shrinkage prevention while increasing fluidity and flowability.
다른 한편, 본 발명에서는 상기 차폐칸막이(30)의 표면에 내침식성, 내오염성, 내열성, 방수성, 산화방지성을 갖출 수 있도록 방식억제제가 스프레이 코팅될 수 있다.On the other hand, in the present invention, a corrosion inhibitor may be spray-coated on the surface of the
이때, 상기 방식억제제는 폴리우레탄수지 100중량부에 대해, 에틸렌디아민테트라아세트산 4.5중량부, 디메틸벤질리덴솔비톨 3.5중량부, 폴리다이아조디페닐아민 5.5중량부를 첨가 혼합하여 조성된다.At this time, the anticorrosion agent is prepared by adding and mixing 4.5 parts by weight of ethylenediaminetetraacetic acid, 3.5 parts by weight of dimethylbenzylidene sorbitol, and 5.5 parts by weight of polydiazodiphenylamine with respect to 100 parts by weight of the polyurethane resin.
여기에서, 에틸렌디아민테트라아세트산(Ethylenediaminetetraacetic acid)은 산화에 의한 산패를 막고 중성화를 억제하여 성형품의 내식성을 강화시키기 위해 첨가된다.Here, ethylenediaminetetraacetic acid is added to prevent rancidity due to oxidation and suppress neutralization to enhance corrosion resistance of molded articles.
또한, 디메틸벤질리덴솔비톨은 성분간 결합력을 증대시켜 성형품의 마모저항성이 저하되는 것을 방지한다.In addition, dimethylbenzylidene sorbitol increases bonding strength between components to prevent deterioration in wear resistance of molded products.
나아가, 폴리다이아조디페닐아민은 다이아조늄 화합물로서, 블럭 표면을 유리화시켜 코팅제에 의한 방오성과 내스티키성을 극대화시키는 장점이 있다.Furthermore, polydiazodiphenylamine is a diazonium compound, and has the advantage of maximizing antifouling and sticky resistance by a coating agent by vitrifying the surface of the block.
이와 같이 구성하게 되면 랙케이스에 고주파 발생기 상호간 전자파 차폐력을 높일 수 있어 고주파 발생기에서 고주파 생성시 발생하는 전자파로 인해 발생되는 기기의 오작동이나 고장을 미연에 방지할 수 있게 된다.With this configuration, it is possible to increase the shielding power of electromagnetic waves between the high frequency generators in the rack case, so that malfunction or failure of devices caused by electromagnetic waves generated when the high frequency generator generates high frequencies can be prevented in advance.
