Abstract
A kind of measuring electrode for electrocardiogram used in front of chest.It has the wiring of logical liquid aperture, electrode sucker frame liquid storage sulculus and sepage micropore that electrode reservoir, electrode sucker, electrode imbibition contact, liquid feeding pressure-equalizing pipe, flat band, electrode slice, electrode link to each other with the electrode sucker, leading wire connector, sucker air duct fitting, lead-in wire and closes the hole.The material of electrode slice is to adopt silver and silver chloride complex.Electrode slice is once molding formed.Airway and contact conductor merging are pressed into a flat band.
The present invention is rational in infrastructure, and is easy to use.Disturb for a short time during measurement, noise is low, and is functional.
Description
The invention belongs to the medical bio electric transducer.
ECG measuring electrode is the important sensing element that obtains the organism electrocardiosignal.Used front ECG measuring electrode is a rubber bulb type metal cup electrode at present.The influence of being breathed easily with the clothes friction is fixed in it and human body front.The front clothes all need be untied easily during measurement and be suffered from cold.The body slimming patient is difficult to fix.Usually the electrode material that adopts is that spedex or copper alloy are silver-plated at present.Seriously corroded when these materials contact with the conductive liquid that contains chloride ion, the electrode potential drift.The electrode potential drift is more serious when particularly just having coated conductive liquid and measuring at once, ECG signal produced disturb and distortion.The present invention has done improvement at above-mentioned shortcoming exactly.
Accompanying drawing is the measuring electrode for electrocardiogram used in front of chest sketch map, (1) is electrode reservoir among the figure, (2) be the electrode sucker, (3) be the imbibition contact of electrode, (4) be the liquid feeding pressure-equalizing pipe, (5) be flat band, (6) are electrode slices, and (7) are the logical liquid apertures that electrode links to each other with the electrode sucker.(8) (9) are electrode sucker frame liquid storage sulculus and sepage micropore, and (10) are leading wire connectors, and (11) are the sucker air duct fittings, and (12) are that the hole is closed in the wiring of lead-in wire.
Main points of the present invention are that the front ECG measuring electrode has electrode reservoir, the electrode sucker, electrode imbibition contact, liquid feeding pressure-equalizing pipe, flat band, electrode slice, the logical liquid aperture that electrode links to each other with the electrode sucker, electrode sucker frame liquid storage sulculus and sepage micropore, leading wire connector, the sucker air duct fitting, the hole is closed in the wiring of lead-in wire.The electrode slice material can adopt silver and silver chloride complex.Electrode slice can be once molding formed.Lead-in wire and electrode slice can not have joint, and airway that communicates with the sucker inner chamber and electrode can be merged into a flat band, and it can be once molding formed with sucker.
Electrode of the present invention, can form reversible half-cell with chloride ion, electrode potential is very stable, has strong corrosion resistance, the back side of electrode slice (6) can be provided with reservoir (1), can be provided with electrode imbibition contact (3) with the electrode slice connecting place, it is communicated with reservoir, makes the electrode slice surface energy keep wetting state, not only electrode potential is difficult for drift, can reduce simultaneously the contact resistance of electrode slice and skin, this structure by electrode imbibition body and contact skin, electrode is not subject to disturb.Electrode sucker frame can be made with the hard rubber elastomeric material.At electrode sucker scuncheon, can be provided with liquid storage sulculus (8) and logical liquid micropore (9), make electrode sucker frame keep moistening, sucker and contact skin are difficult for gas leakage like this.End at flat band can be provided with the air duct fitting (11) of leading wire connector (10) and sucker so that be connected with air-breathing ball with electrocardiographic recorder.Between electrode sucker and the reservoir, can be provided with liquid feeding pressure-equalizing pipe (4), it both can do the liquid-feeding tube of reservoir, can make the pressure-equalizing pipe of reservoir and sucker inner chamber during measurement again.The very fast extinction of conductive liquid in the time of can avoiding owing to sucker inner chamber negative pressure like this, airway is with contact conductor and become a flat band, strengthen its intensity, and flat with on can be provided with lead-in wire wiring close hole (12), can connect the lead-in wire of electrode with leading wire connector, available rubber glue is shut and is prevented that pigtail splice from being corroded after connecting.
The present invention is rational in infrastructure, and is easy to use, disturbs for a short time during measurement, and noise is low, and is functional.
