[Detailed description of the invention] disposable medical surface electrodes The present invention generally relates to disposable medical surface electrodes and methods of making the same.

Various types of disposable medical surface electrodes are commercially available. For these commercially available electrodes, the manufacturing Apply a conductive substance to ensure electrical contact with the skin or during use. It is necessary to apply adhesive active substances to ensure adhesion. Also, the size of these electrodes The parts have electrical connections, which complicate manufacturing. Therefore, this type of electricity All of the poles are costly and inconvenient to store.

The electrode of the present invention does not include any lead wires, plugs, or push buttons for connection. Also, There is no need to apply conductive substances or adhesive active substances during use. Also, conductive It does not contain any air bubbles or cavities that are infiltrated or covered by a synthetic gel. The electrode of the present invention It has the same appearance and adhesive properties as a regular plaster or self-adhesive bandage. The electrode is Consisting of a lume-like or woven support (1), which is provided with a conductive adhesive or conductivity. The adhesive (2) (Figs. 1 and 6) is applied to the support or a conductive material is applied to the support. A conductive or non-conductive adhesive (4) supporting a thin layer of material (3) is applied to the support. (Figure 4). The thin layer supports powder or fibers or coarse fabric of conductive material. It is formed by being attached to the surface of the carrier. If necessary, use adhesive with high conductivity (1 In order to obtain 1), the conductive substance (3) is mixed or dissolved in the adhesive (2). Therefore, the electrical conductivity of the adhesive can be improved (Figure 1.2.3).

The conductive substance (3) mixed or dissolved in the adhesive (2) must be non-corrosive, Preferably, it does not induce allergies and is not toxic. For this purpose, in particular Use graphite or aluminum llN or fine powder or salt solution. It is preferable to use Select one of the above depending on the composition of the adhesive used good. Preferably, the adhesive is non-allergenic and non-toxic.

According to a preferred manufacturing method, a conductive substance is added to the adhesive while it is in a liquid state during the manufacturing process. mix or dissolve the substance into the adhesive. If mixing or dissolution is difficult, use a catalyst. It is desirable to use materials that facilitate the use or operation of the materials. Mixing ratio The melt ratio is chosen to maintain good adhesion and at the same time minimize electrical resistance. Ru.

Around the conductive adhesive layer The surrounding support surface is coated with a non-conductive adhesive layer (Fig. 14) or conductive. The entire surface of the support between the adhesive layer (11) and the support (1) is covered with a non-conductive adhesive layer. (Figure 15).

A specific example of the adhesive bandage type electrode of the present invention (△) is an electric curve recording device or an electric therapy device. The disposable electrode (E) may be configured to adhere to the back side of the disposable electrode (see Section 9.1). 0, 11, 12 and 13). A specific example of the adhesive tape type electrode of the present invention (B) is as follows: Electrode or plug of electric wire for connection of electric curve recording device or electrotherapy device (F or F) may be configured to adhere to the front side of the disposable electrode (Figures 7 and 8). child , the conductivity of the electrical connection of the electrical curve recording device or the electrotherapy device and the disposable electrode. electrical contact with the adhesive layer (11) and contact between the disposable electrode and the skin. to create an electrical connection between the electrical connections of the electrical curve recording device or electrotherapy device and the skin. conducts. This continuity is created through the adhesive layer itself (11 or 6) of the disposable electrode. 1.2゜3.5 and 6) or through a conductive substance (5) . This electrically conductive material must be in contact with the connections of the electrical curve recording device or electrotherapy device. The sea urchin is attached to the adhesive layer of the disposable electrode.
