Detailed description of the invention
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
As shown in Figure 1 to Figure 2, present embodiments provide a kind of disposable medical electrode sheet, the conducting terminal 4 comprising connector 1, insulator cap 2, conductive rubber 3 and be connected with conductive rubber 3; Wherein connector 1 is made up of metal material, the top of insulator cap 2 is provided with opening 21, conducting terminal 4 comprises Plug Division 41 and contact site 42 integrated with Plug Division 41, described Plug Division 41 is fastenedly connected through opening 21 and connector 1, and insulator cap 2 is crimped between described contact site 42 and described connector 1.
Described conducting terminal 4 is by base material and is coated with Ag/AgCl coating at substrate surface and forms, in this enforcement, the thickness of described Ag/AgCl coating is 0.3 ~ 0.5 μm, electrode slice non-polarized phenomenon when acquired signal is produced, thus improves the acquisition quality of signal.In addition, ABS plastic selected by described base material.
Described connector 1 comprises base 12 and is caved inward by base 12 center and forms the joint pin 11 of hollow.Described joint pin 11 is fastenedly connected with described Plug Division 41, to avoid very thin silver chloride layer to make it constantly wear down because of operations such as plugs, thus affects the electric conductivity of electrode slice; Described base 12 is conflicted, so that fixed conductive terminals 4 and insulator cap 2 with described insulator cap 2 top.Described joint pin 11 passes through snap-fastener or grafting or thread connecting mode and is connected with rear end equipment.Wherein said rear end equipment can as two Chinese invention patent applications (number of patent application is respectively: the stationary positioned device 201320367628.6 and 201320367777.2) and with this apparatus structure or the same or similar equipment of character, the concrete structure of this equipment no longer specifically repeats at this.
Described conductive rubber 3 to be installed in insulator cap 2 and bonding with conducting terminal 4 integral.In the present embodiment, conductive rubber 3 is the medical conductive pressure sensitive adhesive of ultraviolet light polymerization.In order to human body skin good contact, in the present embodiment, conductive rubber 3 is provided with fillet with the edge in contact human skin face, and this contact surface is higher than the top edge face of insulator cap 2.
Shown in composition graphs 3, in order to fixed conductive terminals 4, be also convenient to conductive rubber 3 curing molding and ensure that the concordance of conductive rubber 3 and conducting terminal 4 contact surface, in this enforcement, insulator cap 2 shape is set to " bowl " shape.In order to extenuate with human contact after because extruding the conductive rubber 3 that produces deformation and ensureing signals collecting performance, described insulator cap 2 is formed by the one-body molded compacting of elastic insulating material.Described elastic insulating material is preferably silica gel in the present embodiment.In the present embodiment, described opening 21 is circular and is positioned at insulator cap 2 top center place.But be fixed between connector 1 and conducting terminal 4 in order to make to be convenient to connector 1 by insulator cap 2, the diameter of described opening 21 is less than the interior diameter of insulator cap 2, thus make connector 1, insulator cap 2 is fixedly connected with integral with conducting terminal 4.
As shown in Figure 4, conducting terminal 4 is first conflicted with the fastening base 12 as connector 1 of joint pin grafting of connector 1 through the opening 21 on insulator cap 2 by disposable medical electrode sheet of the present invention, then to be adhered to by conductive rubber 3 on conducting terminal 4 and to be integrally formed.When using this disposable medical electrode sheet, first this electrode slice is connected in rear end equipment, then by conductive rubber 3 and contact human skin, finally realizes information gathering.Therefore, electrode slice of the present invention can be applicable to be applied to EEG measuring, myoelectricity measurement, bio-impedance imaging technique, through electrocutaneous stimulation and biofeedback system, be wherein particularly useful for the correlative technology fields such as Breast electrical impedance fault imaging (EIT) equipment.
Upper content is only preferred embodiment of the present invention, and for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, this description should not be construed as limitation of the present invention.
