An electrode device for sustainable detection includes: a fixing frame provided with a fixing groove on one side； a sponge body correspondingly embedded in the fixing groove in a detachable manner, provided with a wire embedding groove, and can provide electrical signals for direct touch with surface skin or mucous membrane to be read； a liquid delivery tube, one end of which is connected to a liquid storage barrel that can store an electrolytic fluid, and the other end of which is connected to wire embedding groove, with one end of the liquid storage barrel being provided with a coupling element； and an electrode element, which can penetrate inside the liquid delivery tube, with one end of the electrode element being arranged in the wire embedding groove, and the other end of the electrode element being placed inside the liquid storage barrel. When the electrode element infiltrated with the electrolytic fluid is in contact with the skin or mucous membrane on any surface of the human body, the coupling element can direct its electrical signal to the outside or introduce current into the human body, electrical signals of the patient's relevant position can be monitored at any time,expected to be applied for most patients in medical places in the future.本發明係提供一種可持續性探測之電極裝置，包含有：一固定架，其一側設有一固定槽；一海棉體，其係以可拆卸之方式對應嵌固於該一固定槽，且該海棉體環設有一埋線槽，並可供直接碰觸於待讀取之表面皮膚或黏膜位置之電訊號；一送液管，其一端皆連接設有一可存放一電解流體之儲液筒，另一端連接於該埋線槽，而該儲液筒之一端設有一耦合件；以及一電極件，其係可穿設於該送液管之內部，且該電極件之一端可設置於該埋線槽，並將該電極件之另一端設置於該儲液筒之內部；藉此，當浸潤於該電解流體之電極件接觸於人體任一表面皮膚或黏膜位置時，該耦合件可將其電訊號導引至外界或將電流導入人體，可隨時監控病患相關位置之電訊號，以期未來可適用於應用在醫療場所中多數之患者。
