Description

Disposable ECG electrodes

The utility model relates to an instrument for measuring or recording the biological current of a human body or parts of a human body, in particular to a disposable electrocardiographic electrode.

Disposable ECG electrode is a biosensor in medical equipment, suitable for ECG monitoring, and can also be used for electrocardiogram, electrohepatogram monitoring and physical therapy. Commonly used disposable ECG electrodes are composed of lead wire buckle, adhesive paste, electrode core, conductive paste, container for holding conductive paste, anti-adhesive layer and trademark paper. The electrode core is made of mushroom-shaped plastic products, which are electroplated with silver and chlorine It is made by chemical treatment, and an Ag-AgCl plating layer is formed on the surface of the plastic product. The handle of the electrode core passes through the container arranged upside down, the adhesive paste and the center hole of the label paper, and the lead buckle is riveted on the handle of the electrode core. The conductive paste fills the container and the outside is sealed with a release layer. During clinical use, the anti-adhesive layer is torn off and pasted on the human body. This disposable ECG electrode has the following defects: (1) the structure is complex and troublesome to manufacture; (2) the electrode core must be made of precious metal silver, which has a high cost; (3) the electrode core must be electroplated, which will pollute the environment; (4) The electrode core has mushroom-shaped protrusions, which can easily cause discomfort to patients in clinical use; (5) The conductive paste is easy to dry, which affects the performance of the electrode.

The purpose of this utility model is to provide a novel disposable electrocardiogram electrode, which uses a circular tin alloy sheet as the electrode sheet to replace the electrode core, and replaces the conductive paste and its container with a sheet-like pressure-sensitive conductive adhesive, so that the electrode structure The invention is simple, easy to make, lower in cost, convenient to use, and does not produce environmental pollution.

The technical measures taken to realize the purpose of this utility model are: use circular tin alloy sheets to make electrode sheets to replace the electrode cores with complicated manufacturing processes, avoid environmental pollution, save precious metal silver, and use sheet-like pressure-sensitive conductive adhesives to replace conductive pastes and The container makes the structure more reasonable, and the conductive adhesive is not easy to dry for long-term storage.

Figure 1 is a schematic diagram of the design of the disposable ECG electrode structure.

As shown in Figure 1, the disposable ECG electrode of this design is composed of lead buckle 1, adhesive paste 2, electrode sheet 3, conductive glue 4, anti-adhesive layer 5 and trademark paper B, which are arranged coaxially. The head of 1 passes through the central hole of the glue paste 2 and the label paper B, the bottom of the lead wire buckle 1 and the electrode sheet 3 are pasted on one of the pasting surfaces of the glue paste 2, and the electrode sheet 3 is a circular tin alloy sheet, which is conductive Adhesive 4 adopts pressure-sensitive conductive adhesive in sheet form.

Compared with the existing Ag-AgCl disposable ECG electrodes, this solution has the following outstanding advantages:

1. Using sheet-shaped tin alloy electrode sheets and sheet-shaped pressure-sensitive conductive adhesives, the structure is simple and easy to manufacture;

2. The electrode sheet does not need electroplating, no environmental pollution, saving precious metal silver, and reducing costs;

3. The electrode sheet is sheet-shaped, without mushroom-shaped protrusions, and the patient does not feel uncomfortable during clinical use;

4. Sheet-shaped pressure-sensitive conductive adhesive is not easy to dry after long-term storage, and the electrode performance is stable.
