本発明はマイナス電界に人体を横臥することにより、人体の帯電微粒子を調整する電位治療と、人体を暖めることにより血行を良好にして肩こり等をやわらげる温熱治療とが行える電位・温熱組合せ家庭用電気治療器に関する。 The present invention is a combination of electric potential and heat that can be used for electric potential treatment that adjusts the charged fine particles of the human body by lying down on a negative electric field and thermal treatment that improves blood circulation and softens the stiff shoulders by warming the human body. It relates to a treatment device.
電位治療器は大地絶縁された電床板にマイナス電圧を印加することにより形成された電界領域に人体を置くことによって、生体の帯電微粒子を調整する家庭用の電気治療器の一種であり、温熱治療器は、電気発熱体等の加温体によって人体を暖めることにより血行を良好にして、肩こり、筋肉痛等を癒す家庭用の温熱治療器の一種である。従来これらの治療器を組合せ敷き布団用に構成して、寝ながら治療を受けることができるようにしたものがある。
本発明者等は先の発明（特願２０１１―１４９９１３）において、上記の如き敷き布団形式の電位・温熱組合せ家庭用電気治療器において、面状発熱体の安全装置として装備した面センサーと、電位治療用マイナス電位出力用電極としての電床板を同一の面状導電体で兼用するように構成したものを発明した。
An electric potential therapy device is a type of home-use electrotherapy device that adjusts charged particles in a living body by placing a human body in an electric field region formed by applying a negative voltage to a ground-insulated electric floor plate. The device is a type of home thermotherapy device that warms the human body with a warming body such as an electric heating element to improve blood circulation and soothe stiff shoulders and muscle pain. Conventionally, these treatment devices are configured for combination mattresses so that they can receive treatment while sleeping.
In the previous invention (Japanese Patent Application No. 2011-149913), the inventors of the present invention have a surface sensor equipped as a safety device for a planar heating element and a potential treatment in a mattress-type electric potential / heat combination home treatment device as described above. Invented an electric floor plate as a negative potential output electrode for use with the same planar conductor.
しかして、電床板を従来面発熱体の針刺しなどの障害、ならびに面状発熱体の電気絶縁フイルムの絶縁劣化を検知して、安全に使用するために設けた面状導電体からなる面センサーと共用することにより、構造が簡単、軽量で引いては安価に提供できるようにした電位・温熱組合せ家庭用電気治療器は、面状発熱体に通電して、加温しながら電床版に電位電圧を印加すると、温度上昇とともに面状発熱体の電気絶縁フイルムとしての塩ビフイルムが温度―抵抗負特性（ＮＴＣ特性）を持つ電気絶縁抵抗低下で電位電圧が低下するという課題を生じる。 Thus, the surface sensor made of a planar conductor provided for safe use by detecting the electric floor plate, such as needle sticking of the conventional surface heating element, and the insulation deterioration of the electrical insulation film of the sheet heating element, The electric / heat combination household electric treatment device that is simple and lightweight and can be provided cheaply by pulling it in common is used to supply electric potential to the electric plate while energizing the sheet heating element and heating it. When a voltage is applied, as the temperature rises, the PVC film as the electrical insulation film of the planar heating element has a problem that the potential voltage decreases due to a decrease in electrical insulation resistance having a negative temperature-resistance characteristic (NTC characteristic).
すなわち、面状発熱体を構成する電気絶縁フイルムとしての塩ビフイルムの電気絶縁抵抗が面状発熱体の温度上昇とともに低下することにより、電位発生電極としての面センサーを兼ねた電床板の電位電圧が面状発熱体側に引かれて、設定の電位電圧が低下して、電位治療としての性能が低下する不具合を生じる。 In other words, the electrical insulation resistance of the PVC film as the electrical insulating film constituting the planar heating element decreases as the temperature of the planar heating element decreases, so that the potential voltage of the electric floor plate that also serves as the surface sensor as the potential generating electrode is reduced. When pulled to the planar heating element side, the set potential voltage is lowered, resulting in a problem that the performance as a potential treatment is lowered.
しかしながら、電床板は面センサーも兼ねることから、面センサーとしての針刺し検知および面状発熱体の電気絶縁劣化を検知する安全性能も有していなければならない。 However, since the electric floor board also serves as a surface sensor, it must also have safety performance for detecting needle sticks as a surface sensor and detecting electrical insulation deterioration of the planar heating element.
上記のことから、本発明はこれら観点に立って、電床板と面センサーを兼用することにより、軽量で安価な治療器を提供するものにおいて、電床板としての性能を維持するとともに、面センサーとしての性能も担保する治療器を得るものである。 From the above, the present invention is based on these viewpoints, and provides a lightweight and inexpensive treatment device by using both an electric floor plate and a surface sensor, while maintaining the performance as an electric floor plate and as a surface sensor. To obtain a treatment device that also guarantees the performance.
本発明は面センサーを兼ねた電床板と、面状発熱体との間に４mm２〜１００mm2及び綿糸換算略２０番手（約２５０d）の糸径の寒冷紗のような網状布帛を挟装することにより、面状発熱体が発熱しているときにあっても、印加した電位電圧の降下も少なく、また面状発熱体の電気絶縁温度―抵抗負特性（ＮＴＣ特性）をも検知して面センサーとしての針刺し検知および絶縁劣化検知性能も担保し得る構成の電位・温熱組合せ家庭用電気治療器を提供するものである。 According to the present invention, a net-like fabric such as a cold cloth having a diameter of 4 mm 2 to 100 mm 2 and a cotton thread equivalent of about 20th (about 250 d) is sandwiched between an electric floor plate also serving as a surface sensor and a sheet heating element. By this, even when the sheet heating element is generating heat, the applied voltage drop is small, and the surface sensor detects the electrical insulation temperature-negative resistance characteristic (NTC characteristic) of the sheet heating element. It is intended to provide a home-use electrotherapy device with a combination of electric potential and heat that can guarantee the needle stick detection performance and insulation deterioration detection performance.
敷布団に内装した電床板に１０００Ｖ以下のマイナス低電圧を印加して、敷布団上面に電界域を作り、敷布団に横臥した治療者にマイナス電位を与えて、人体の帯電微粒子のバランスを調整して、頭痛・肩こり・不眠症・慢性便秘を緩解する効能効果が得られる家庭用電気治療器において、面状導電体の電床板と面状発熱体とを積層一体にして、面状発熱体を発熱させて温まりながら、あるいは温熱治療を受けながら電位治療を受けることのできる、電位・温熱組合せ家庭用電気治療器にあって、面状発熱体の電気的安全を担保する面センサーを上記電床板と兼用させ、且つ電床板と面状発熱体の間に４mm2〜100mm2目及び綿糸換算略20番手（約250d）糸径の網状布帛を挟装したものである。 Apply a minus low voltage of 1000V or less to the electric floor board installed in the mattress, create an electric field area on the upper surface of the mattress, give a negative potential to the therapist lying on the mattress, and adjust the balance of charged fine particles of the human body, In a home-use electrotherapy device that can relieve headache, stiff shoulders, insomnia, and chronic constipation, the sheet heating element and sheet heating element are laminated together to heat the sheet heating element. This is a combination of electric potential and thermal electric appliances that can receive electric potential treatment while being warmed or undergoing thermal treatment, and a surface sensor that ensures the electrical safety of the planar heating element is also used as the above-mentioned electric floor plate it is allowed, in which and electrostatic floor and the planar heat generating element 4 mm 2 100 mm 2 th and cotton converted substantially 20 fastest between (about 250d) mesh fabric yarn diameter was sandwiched.
上記のように電床板と面状発熱体の間に網状布帛を挟装させたことにより、温度―抵抗負特性（ＮＴＣ特性）を持つ塩ビフイルムのごとき面状発熱体の電気絶縁フイルムを利用して、針刺し及び電気絶縁劣化における電気的安全を担保する面センサーを電床板と兼用しても、設定電位電圧を確保することができ、かつ面センサーとしての電気安全性能も確保できる。 By using a net-like fabric sandwiched between the electric floor plate and the sheet heating element as described above, an electric insulation film of a sheet heating element such as a PVC film having a negative temperature-resistance characteristic (NTC characteristic) is used. Thus, even if a surface sensor that ensures electrical safety in needle sticking and electrical insulation deterioration is also used as an electric floor plate, the set potential voltage can be secured, and the electrical safety performance as a surface sensor can be secured.
さらに、温熱治療のために設けた面状発熱体の安全装置としての面センサーを、電位治療器の電極としての電床板に兼用させる構成にしたことにより、軽量で安価な電位・温熱組合せ家庭用電気治療器として提供することができる。 In addition, by combining the surface sensor as a safety device for the planar heating element provided for thermal therapy with the electric floor plate as the electrode of the potential therapy device, it is a lightweight and inexpensive combination of potential and thermal household use. It can be provided as an electrotherapy device.
本発明は、低圧の電位・温熱組合せ家庭用電気治療器において、電床板と面状発熱体の間に網状布帛を挟装することにより、電床板に印加した設定電位電圧の降下が少なく、電床板に兼用した面センサーとしての性能も維持して、構造が簡素化され軽量になるとともに、安価になる効果がある。 According to the present invention, in a low-voltage electric potential / heat combination home electrotherapy device, a net-like cloth is sandwiched between an electric floor plate and a sheet heating element, so that a decrease in the set potential voltage applied to the electric floor plate is small. While maintaining the performance as a surface sensor that also serves as a floor board, the structure is simplified and light weight, and the cost is reduced.
電床板への電圧出力側に電位電圧検知回路なる電圧出力モニター機能を設けてマイコンに対して電圧出力可否信号出すことによりマイコンで発光ダイオードの点滅を行う。電床板と兼用する面センサーは面状発熱体からの一定以上の漏洩電流（例えば１００μＡ以上）を面状発熱体から受けたときにマイコンの作用で面状発熱体への電気の供給を止める。また、面センサーを兼ねる電床板に印加される低圧マイナス電圧は、商用交流電源から絶縁された状態で変換された直流電源で、且つ商用交流電源と高インピーダンスにて接続された直流電源を昇圧して得られた電圧である。温度―抵抗負特性（ＮＴＣ特性）のフイルムで電気絶縁された面状発熱体に対面積層された、面状導電体からなる電床板との間に例えばポリエステル糸で織られた４mm2〜１００mm2の目、及び略綿糸２０番手の径を有する寒冷紗のような網状布帛を挟装する。 A voltage output monitoring function, which is a potential voltage detection circuit, is provided on the voltage output side to the electric floor plate, and a light output diode is blinked by the microcomputer by outputting a voltage output enable / disable signal to the microcomputer. A surface sensor that also serves as an electric floor plate stops the supply of electricity to the planar heating element by the action of the microcomputer when a leakage current (for example, 100 μA or more) from the planar heating element is received from the planar heating element. In addition, the low voltage minus voltage applied to the electric floor plate that also functions as a surface sensor is a DC power source converted in a state insulated from the commercial AC power source, and boosts the DC power source connected to the commercial AC power source with high impedance. This is the voltage obtained. Temperature - resistance negative characteristics are facing laminated to the film in the electrically insulating the planar heating element (NTC characteristics), 4 mm was woven in for example polyester yarn between the electrostrictive floorboard from the planar conductor 2 100 mm 2 And a net-like fabric having a diameter of about 20th cotton yarn, such as a cold chill.
本発明の一実施例を図に基づいて説明する。図１は本発明を実施するための面状発熱体１を示し、これは両側に銅線を織り込んだ電極帯２，２を設けた織布に、カーボン導電塗料を塗布して、表裏面に温度―抵抗負特性(ＮＴＣ特性)の塩ビフイルムをラミネートして電気絶縁して形成される。電極帯２，２からは端子３，３を介してリード線４，４が導出されている。図２は面センサーを兼ねた電床板５を示し、これは塩ビフイルム等電気絶縁フイルム６の片面にカーボン導電塗料を印刷してなる導電面７を形成して、導電面７から端子８を介してリード線９が導出されている。 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a sheet heating element 1 for carrying out the present invention, in which a carbon conductive paint is applied to a woven fabric provided with electrode bands 2 and 2 woven with copper wires on both sides, and the front and back surfaces are coated.

これら面状発熱体１と電床板５は、面状発熱体１の片面に電床板５の導電面７を対面させて積層一体に形成されている。このとき、面状発熱体１と電床板５の間には図４のように網状布帛２１が挟装されている。 The planar heating element 1 and the electric floor plate 5 are integrally formed with the conductive surface 7 of the electric floor plate 5 facing one side of the planar heating element 1. At this time, a mesh fabric 21 is sandwiched between the sheet heating element 1 and the electric floor plate 5 as shown in FIG.

積層一体に形成された面状発熱体１および電床板５は、図３、図５に示されるように敷き布団１０の綿２０，２０に接着して、外皮１９，１９に内装されている。敷き布団１０の角部には電気接続器１１が装着されており、そこから本体コード１２を介してコントローラー１３に面状発熱体１および電床板５のリード線４，９が電気接続される。１４は商用交流電源に接続されるプラグ付き電源コードである。 The planar heating element 1 and the electric floor board 5 formed integrally with each other are bonded to the cottons 20 and 20 of the mattress 10 and housed in the outer skins 19 and 19 as shown in FIGS. An electrical connector 11 is attached to the corner portion of the mattress 10, and the sheet heating element 1 and the lead wires 4 and 9 of the electric floor plate 5 are electrically connected to the controller 13 through the main body cord 12 from there. Reference numeral 14 denotes a power cord with a plug connected to a commercial AC power source.

It is.
図５は本発明電位・温熱組合せ家庭用電気治療器を敷き布団形態に実施した図３の敷き布団１０部の断面を示し、外皮１９・１９に被包された固綿２０・２０に上下挟まれて、積層された面状発熱体１と電床板５が設けられている。 FIG. 5 shows a section of the mattress 10 in FIG. 3 in which the electric / heat combination home electric treatment device of the present invention is implemented in the form of a futon, and is sandwiched between upper and lower cottons 20 and 20 encased in outer skins 19 and 19. A laminated sheet heating element 1 and an electric floor plate 5 are provided.
図６は、電気系統を示すコントローラー１３に収められた電子回路ブロック図である。商用交流電源（１００Ｖ〜２２０Ｖ）はスイッチング安定化電源回路Ａおよび面状発熱体１への電気供給を制御する発熱体制御回路Ｂに投入される。 FIG. 6 is an electronic circuit block diagram housed in the controller 13 showing the electrical system. The commercial AC power supply (100 V to 220 V) is supplied to the switching stabilization power supply circuit A and the heating element control circuit B that controls the electric supply to the planar heating element 1.
電源回路Ａにおいては、スイッチング安定化電源により、たとえば直流５Ｖに変換されて、マイコンＣおよび電位治療のためのマイナス電位発生回路Ｄに投入される。マイナス電位発生回路Ｄでは、たとえばマイナス直流６００Ｖに昇圧されて電床板５に電気接続されている。スイッチング安定化電源回路Ａと商用交流電源とは、基本的には絶縁されているが直流出力を高インピーダンス素子Ｇを介して商用交流電源と接続することにより、マイナス電位発生回路Ｄの出力基準を商用交流電源のアース電位とすることができる。 In the power supply circuit A, it is converted into, for example, direct current 5V by a switching stabilized power supply, and supplied to the microcomputer C and the negative potential generation circuit D for potential treatment. In the negative potential generating circuit D, for example, it is boosted to negative DC 600V and is electrically connected to the electric floor plate 5. The switching stabilized power supply circuit A and the commercial AC power supply are basically insulated, but by connecting the DC output to the commercial AC power supply via the high impedance element G, the output reference of the negative potential generating circuit D can be set. It can be the ground potential of a commercial AC power supply.
電床板５へのマイナス電圧出力側には電圧検知回路Ｅが設けられており、電圧印加状況をマイコンＣに投入する。マイコンＣにおいては、マイナス電位発生回路ＤへのＯＮ／ＯＦＦ制御および発熱体制御回路ＢへのＯＮ／ＯＦＦが面状発熱体１に設けられた図示しない温度センサー（感熱線あるいはサーミスター）からの信号を受けて行われる。 A voltage detection circuit E is provided on the negative voltage output side to the electric floor plate 5, and a voltage application state is input to the microcomputer C. In the microcomputer C, ON / OFF control to the negative potential generation circuit D and ON / OFF to the heating element control circuit B are supplied from a temperature sensor (heat sensitive line or thermistor) (not shown) provided in the sheet heating element 1. Performed in response to a signal.
この場合、マイコンＣからマイナス電位発生回路Ｄへの信号がＯＮにもかかわらず電位電圧検知回路Ｅで電圧出力が検知できないときはマイコンＣを介して発光ダイオード１６或は１８を点滅するなどして報知する。 In this case, when the voltage output cannot be detected by the potential voltage detection circuit E even though the signal from the microcomputer C to the minus potential generation circuit D is ON, the light emitting diode 16 or 18 is flashed via the microcomputer C. Inform.
また、電床板５への電位電圧出力回路上には漏洩電流検出回路Ｆが設けられており、面状発熱体１から、例えば針刺し、あるいは面状発熱体１の電気絶縁フイルムが絶縁低下したときに受ける漏洩電流を検出してマイコンＣに送信することで、面状発熱体１への通電をＯＦＦして使用上の安全を確立する。この場合、電床板５への電位治療電圧を、スイッチング安定化電源回路Ａ以降の直流５Ｖから昇圧したことにより、面状発熱体１への商用交流電源の漏洩電流と差別化され、電床板５は面センサーと兼用できる。 In addition, a leakage current detection circuit F is provided on the potential voltage output circuit to the electric floor plate 5 so that, for example, a needle stick or an electrical insulation film of the planar heating element 1 is insulated from the planar heating element 1. By detecting the leakage current received at the terminal and transmitting it to the microcomputer C, the energization of the planar heating element 1 is turned off to establish safety in use. In this case, the potential treatment voltage to the electric floor plate 5 is boosted from the direct current 5 V after the switching stabilized power supply circuit A, so that it is differentiated from the leakage current of the commercial AC power source to the planar heating element 1. Can also be used as a surface sensor.
面状発熱体１と電床板５の間に、網目４mm2〜１００mm2、綿糸略２０番手相当の径の糸で織った寒冷紗のような網状布帛２１を挟装することにより、常温において面状発熱体１と電床板５間の絶縁抵抗を100MΩ以上維持したものが、使用温度６０℃においては７０MΩ程度まで下がり、さらに例えば温度制御の異常により面状発熱体１が高温になったときにおいては１MΩと低下する。これは、高温上昇により塩ビフイルムが柔軟性を帯びて、網状布帛２１の目を介して電床板５の導電面と面状発熱体１の絶縁フイルムが接合して、面状発熱体１の絶縁劣化によるリーク電流が電床板５に伝わり、面状発熱体１への通電を遮断する。誤って針刺しをしたときには、面状発熱体１の導電部７と電床板５の導電面が針を介して電気導通することから、面状発熱体１の通電を遮断する。 Between the planar heating element 1 DOO conductive floor plate 5, a mesh 4 mm 2 100 mm 2, by sandwiched reticulated fabric 21 such as cheesecloth woven yarn diameter of cotton substantially 20 fastest corresponds, surface at room temperature When the insulation resistance between the heating element 1 and the electric floor plate 5 is maintained at 100 MΩ or more, it drops to about 70 MΩ at the operating temperature of 60 ° C., and when the planar heating element 1 becomes high temperature due to abnormal temperature control, for example. It drops to 1MΩ. This is because the PVC film becomes flexible as the temperature rises, and the conductive surface of the electric floor plate 5 and the insulating film of the planar heating element 1 are joined through the mesh of the mesh fabric 21 to insulate the planar heating element 1. Leakage current due to deterioration is transmitted to the electric floor plate 5, and the energization to the planar heating element 1 is cut off. When the needle is punctured by mistake, the conductive portion 7 of the sheet heating element 1 and the conductive surface of the electric floor plate 5 are electrically connected via the needle, so that the sheet heating element 1 is cut off from being energized.
発明者の実測では、網状布帛に代えて通常の織布、不織布を面状発熱体１と電床板５の間に挟装したときは、面状発熱体１を６０℃に上げても１００MΩ以上を維持して面センサーとしての機能を発揮しえない。また、４０MΩ以下に面状発熱体１と電床板５間の絶縁抵抗が下がると、電位電圧が急激に低下して、電位治療器としての機能が失われる。これにたいして、４mm2〜１００mm2目及び綿糸換算略20番手（約250ｄ）の糸径を持つ網状布帛を面状発熱体１と電床板５の間に挟装したときは、面状発熱体１の温度が６０℃の設定温度のとき７０MΩを維持して９０℃の異常高温になったときは、絶縁抵抗は１MΩ以下まで低下することが確認できた。 According to the actual measurement by the inventors, when a normal woven fabric or non-woven fabric is sandwiched between the sheet heating element 1 and the electric floor board 5 instead of the mesh cloth, even if the sheet heating element 1 is raised to 60 ° C., 100 MΩ or more. Can not function as a surface sensor. Further, when the insulation resistance between the planar heating element 1 and the electric floor plate 5 is lowered to 40 MΩ or less, the potential voltage is suddenly lowered and the function as a potential treatment device is lost. Against this, when sandwiched 4 mm 2 100 mm 2 th and cotton converted substantially 20 fastest reticulated fabric having a yarn diameter (about 250d) between the planar heating element 1 DOO conductive floor 5, the planar heating element 1 It was confirmed that the insulation resistance decreased to 1 MΩ or less when the temperature of 70 ° C. was maintained at 70 ° C. and an abnormally high temperature of 90 ° C. was reached.
従って、本発明、面状発熱体１と電位治療の負電圧印加電極としての電床板５の間に４mm2〜１００mm2目及び綿糸換算略20番手（約250ｄ）の網状布帛を挟装することは、電床板５を面状発熱体１の電気的安全を保つ面センサーと兼用させても、面状発熱体１が異常高温になったとき絶縁抵抗が下がり、リーク電流を受けて、面状発熱体１への通電を遮断する。また、温熱治療器として、必要な温度６０℃のときは、絶縁抵抗７０MΩ以上を維持して、温熱治療と電位治療を組み合せたこの種治療器において、電位治療器として印加した電位電圧を低下することもない。 Accordingly, the present invention can be sandwiched reticulated fabric 4 mm 2 100 mm 2 th and cotton converted substantially 20 fastest during the planar heating element 1 and the conductive floor 5 as the negative voltage application electrode potential therapeutic (about 250d) Even if the electric floor plate 5 is also used as a surface sensor for maintaining the electrical safety of the sheet heating element 1, when the sheet heating element 1 reaches an abnormally high temperature, the insulation resistance is lowered and a leakage current is received. The power supply to the heating element 1 is cut off. Further, as a thermotherapy device, when the necessary temperature is 60 ° C., an insulation resistance of 70 MΩ or more is maintained, and in this type of treatment device that combines thermotherapy and potential therapy, the potential voltage applied as the potential therapy device is reduced. There is nothing.
なお、上記実施例においては、両側に電極帯を織り込んだ織布にカーボン等導電塗料を塗布してなる面状発熱体を説明に用いたが、糸に導電塗料を塗布等して、これを横糸に織り込んでなる線面発熱体においても同様の作用効果を得る。 In the above embodiment, a planar heating element formed by applying a conductive paint such as carbon to a woven cloth in which electrode bands are woven on both sides is used in the description. A similar effect can be obtained with a linear heating element woven into a weft.
以上実施例において説明したように、本発明は電位電圧をスイッチング安定化電源から昇圧したことから、治療用電位電圧を安定した電圧として得ることができる。さらに、面状発熱体への発熱電気を商用交流電源から得、電位治療用電圧をスイッチング安定化電源から昇圧して得るようにしたことにより、電床板と面センサーを同一の面状導電体で共用できることから、機器本体は簡素化出来、軽量にできることになり、安価に構成される。このような構成において、面状発熱体と電床板の間に４mm2〜１００mm2の目を有する網状布帛を挟装することにより、電位治療用印加電圧を設定電圧に維持するとともに、異常時には面状発熱体からのリーク電流を電床板で受けて、電気的安全を担保することができる。 As described in the above embodiments, the present invention boosts the potential voltage from the switching stabilized power supply, so that the therapeutic potential voltage can be obtained as a stable voltage. In addition, heat generation electricity to the sheet heating element is obtained from a commercial AC power source, and the potential treatment voltage is boosted from the switching stabilization power source, so that the electric floor plate and the surface sensor are made of the same sheet conductor. Since it can be shared, the main body of the device can be simplified and reduced in weight, and is configured at low cost. In such a configuration, by sandwiched a reticulated fabric having the eyes of 4 mm 2 100 mm 2 while the planar heating element and conductive floor, while maintaining the applied voltage for the potential treatment the set voltage, the abnormal surface Leakage current from the heating element can be received by the electric floor plate to ensure electrical safety.
