Abstract
Abstract An electrocardiographic electrode is disclosed, which is to be held in close contact with a person's skin for deriving a weak voltage from an inner part of the person. The electrode includes a viscous base member to be held in close contact with the person's skin and having a central opening, a reinforcement member bonded to the front surface of the viscous base member to close the opening, a lead connector hook penetrating a central portion of the reinforcement member to be coupled to a lead connector, and an electrode member secured to the underside of the lead connector hook. The viscous base member with the central opening is viscous both on the back surface to be held in close contact with the skin and on the front surface coupled to the lead connector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
186 words
An electrocardiographic electrode to be held in close contact with a person's skin for deriving a weak voltage from an inner part of the person, comprising: a viscous base member to be held in close contact with the person's skin, said viscous base member having front and back viscous surfaces and a central opening; a reinforcement member bonded to the front surface of said viscous base member to close said opening; a lead connector hook penetrating a central portion of said reinforcement member, said connector hook having a portion coupled to a lead connector; an electrode member coupled to said connector hook for relaying the weak voltage from the person's skin; and a waterproof suction electrode member securely covering the portion of said lead connector hook and said front surface of said viscous member; wherein, insofar as said viscous base member with said central opening is viscous both on the front and back surfaces, the back surface of said base member is held in intimate contact with the skin; and said front surface of said base member is firmly bonded to said waterproof suction electrode member.
Claim 2
Dependent Claim
186 words
An electrocardiographic electrode to be held in close contact with a person's skin for deriving a weak voltage from an inner part of the person, comprising: a viscous base member to be held in close contact with the person's skin, said viscous base member having front and back viscous surfaces and a central opening; a reinforcement member bonded to the front surface of said viscous base member to close said opening; a lead connector hook penetrating a central portion of said reinforcement member, said connector hook having a portion coupled to a lead connector; an electrode member coupled to said connector hook for relaying the weak voltage from the person's skin; and a waterproof suction electrode member securely covering the portion of said lead connector hook and said front surface of said viscous member; wherein, insofar as said viscous base member with said central opening is viscous both on the front and back surfaces, the back surface of said base member is held in intimate contact with the skin; and said front surface of said base member is firmly bonded to said waterproof suction electrode member.
Claim 3
Dependent Claim
27 words
