To achieve these goals, the technical solution adopted in the present invention is as follows:
A kind of disposable medical electrode sheet, comprises connector, insulator cap, conductive rubber and the conducting terminal being connected with conductive rubber; Wherein connector is made up of metal material, the top of insulator cap is provided with opening, conducting terminal comprise Plug Division and with the integrated contact site in Plug Division, described Plug Division is fastenedly connected through opening and the connector of insulator cap, insulator cap is crimped between described contact site and described connector.
Preferably, described opening is for circle and be positioned at insulator cap top center place, and its diameter is less than the interior diameter of insulator cap.
Further, insulator cap shape is set to " bowl " shape, and is formed by the one-body molded compacting of elastic insulating material.
Preferably, described connector comprises base and raised up and formed the joint pin of hollow by base center, and described joint pin and described Plug Division are fastenedly connected, and conflicts in described base and described insulator cap top.
Preferably, described conducting terminal is by base material and is coated with Ag/AgCl coating at substrate surface and forms.
Preferably, conductive rubber is installed in insulator cap and is bonding integral with conducting terminal.
Further, conductive rubber is the medical conductive pressure sensitive adhesive of ultraviolet light polymerization.
Further, the thickness of described Ag/AgCl coating is 0.3～0.5 μ m.
Further, described joint pin is connected with rear end equipment by snap-fastener or grafting or thread connecting mode.
Adopt after said structure, the advantage that compared to the prior art the present invention had is: the technical program is by arranging insulator cap and it is shaped as " bowl " shape, can not only facilitate fixed conductive terminals, also be convenient to conductive rubber molding, also guarantee the concordance of the contact surface of conductive rubber and human body surface, thereby reduce because electrode slice contacts produced contact difference with human body, improve the acquisition quality of signal; Electro-medical pole piece used and contact skin area occupied in prior art have also been reduced simultaneously.In addition, the present invention also has feature simple in structure, easy to use.
