BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging device for maintaining hermeticity of a bio-implantable sensor, and more particularly, to a packaging device for maintaining the hermeticity of a bio-implantable sensor, Rectangular packaging; A coil disposed in the inner space of the rectangular package; An implant board disposed at an upper portion of the coil and having through holes at both end portions thereof; A pair of electrodes for measuring a bio-signal installed on one side of the rectangular package so as to be exposed at a through-hole position formed at both side ends of the implant board; And a pair of feedthroughs penetrating the through-hole of the implant board and being fastened to the pair of electrodes. According to the packaging device for maintaining the hermeticity of a bio-implantable sensor proposed in the present invention, the packaging device includes a coil, an implant board, a pair of electrodes and a feedthrough in an internal space of a long-directional packaging, And the implant board and the pair of electrodes can be fastened by using the feedthrough. Thus, the conductivity and hermeticity of the electrocardiograph sensor electrode for ECG measurement can be maintained. In addition, according to the present invention, by forming a step on a pair of electrodes and fastening it to a rectangular package, the contact area with the packaging material can be increased to constitute a structure that can not be structurally separated. And the electrocardiogram noise can be minimized while ensuring the conductivity between the electrodes.본 발명은 생체이식형 센서의 밀폐성 유지를 위한 패키징 장치에 관한 것으로서, 보다 구체적으로는 생체이식형 센서의 밀폐성 유지를 위한 패키징 장치로서, 생체 이식형 센서의 모듈이 설치될 수 있는 내부 공간을 형성하는 장방형의 패키징; 상기 장방형의 패키징의 내부 공간에 배치되는 코일; 상기 코일의 상부에 배치되며, 양측 단부에 스루 홀이 각각 형성되는 임플란트 보드; 상기 임플란트 보드의 양측 단부에 각각 형성되는 스루 홀 위치에서 상기 장방형의 패키징에 일면이 노출되도록 설치되는 생체신호 측정을 위한 한 쌍의 전극; 및 상기 임플란트 보드의 스루 홀을 관통하여 상기 한 쌍의 전극과 체결되는 한 쌍의 피드스루를 포함하는 것을 그 구성상의 특
