Patent KR-20170001073-A (KR)
Inventor: KIM BYUNG JUN
IPC: A61N2/00

Abstract: 인체 신경세포의 내막과 외막은 각각 음전하 또는 양전하를 띠고 있으며 세포질 내의 원형질은 +전자, -전자로 분산되어 유동하고 있다. 이러한 작용을 생체전기현상이라고 할 수 있다. 그런데 이 생체전기를 발생시키는 이온물질이 원형질을 중심으로 거미줄처럼 배치되어 있어서 전후좌우로 +, -전자가 반작용을 하지 않고 서로 끌어당기고 밀어주는, 이른바 +, -의 수수작용으로 서로 유기적 작용을 유지하면서 전기를 발생하게 된다. 이에 따라 세포는 운동을 촉진하면서 생명운동을 이어가게 된다. 
전자기적인 측면에서 보자면, 인체조직은 자성을 띤 세포의 집합체로서 전압으로 강도를 조절할 수 있는 전자석과 같다. 따라서 조직에 조성된 전위 상태에 따라 그 강도도 변화하는 것이다. 
세포는 각종 영양분이 해리되어 전기적 성질을 띤 전해질이 절연체인 지질의 막 즉 세포막 속에 갇히어 양이온과 음이온으로 양분된 작은 전지 또는 자석과 같은 구조의 일면을 보인다. 특히 신경세포에서 이러한 경향이 뚜렷하다. 
이러한 신경세포에 전기장을 걸어주면, 신경세포의 세포 내막에 -70mv의 휴지막전위가 생기므로 신경세포는 +쪽으로 생장할 것이다. 
한편, 신경세포에 자기장을 걸어줄 경우, 자기장의 수직 방향에서 원형이 생기므로 신경세포의 돌기가 일정한 방향을 유지하면서 운동하게 된다. 
본 발명은, 다자극(多磁極)을 3단 또는 4단 육각형 또는 팔각형으로 구성하여 방사형을 이루도록 S, N, S, N, S, N의 순서로 배치하고 중심 쪽으로도 수직형을 이루도록 S, N, S, N, S, N, S, N의 순서로 배치함으로써 다수의 자기장과 전기장이 서로 반작용이 없이 출력되어 병증부위에서 온전한 치료효과를 거두도록 하였다. 
또 중심점에는 단독으로 - 또는 +전극이 출력된다. 이러한 다자극과 단일전극의 동시출력으로 발생되는 전기에너지와 자기에너지는 회진운동을 하면서 조직세포에 작용하게 되는데, 특히 자기장과 전기장이 병증부위 또는 경직된 조직의 세포에 출력되면 세포조직의 운동을 촉진하고 그 결과, 경직된 부위의 비정상전위가 해소되어 혈액순환이 원활해지고 염증부위가 완화되는 효과가 증대한다. 
본 발명의 다자극과 단일전극 동시출력장치 본체는 외곽본체(211)에 내장본체(202)가 장착되어 있어서 넓은 환부의 치료에는 본체 전체를 적용하고, 환부의 범위가 좁을 경우 내장본체(202)만을 분리하여 소형으로 이용할 수 있도록 편리성을 고려한 장치이다.
