Electrocardiogram conductive connecting line electrode

Abstract

The invention provides an electrocardiogram conductive connecting line electrode. The electrocardiogram conductive connecting line electrode comprises a conductive connecting line, an electrode piece and a contact label, wherein the electrode piece is provided with silver foil or silver foil processed through silver chloride, non-woven fabric and conductive hydrogel layers, wherein the non-woven fabric and the conductive hydrogel layers are arranged on two sides of the silver foil and bonded together, the non-woven fabric is provided with a welding opening at the position of the silver foil, and the tail end of the conductive connecting line is welded to the silver foil at the position of the welding opening; the contact label is stuck to the non-woven fabric and covers the welding opening and the tail end of the conductive connecting line. According to the electrode piece, the silver foil is used as the electrode, the electrode and the conductive line are firmly connected in a welding mode, the thickness of the electrode is smaller than 1.2 mm, separation between applied materials of the non-woven fabric and conductive hydrogel of the electrode piece is reduced, and separation of the conductive hydrogel and loaded PET solves the problem of upwarping of the label. The electrode piece is unlikely to fall off in the use process, the electrocardiogram monitoring effect is improved, accurate data are provided for clinical medication and rescue, the success rate of treatment and rescue is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electrocardiogram lead wire electrode. Background technique [0002] At present, the electrocardiogram wires commonly used in hospitals are mostly connected to the electrodes in the form of unipolar plug connectors, wherein the electrodes are plate-type, clip-type or ring-shaped electrodes with suction balls. The above electrodes are easy to install and are suitable for adults. Infants and young children have small limbs, delicate skin, are not under pressure, and love to cry and move. Using adult electrodes often leads to poor contact of the plates, or excessive suction of the ball leads to adverse reactions such as skin congestion, redness, and swelling, which affects the quality of ECG recording or detection. failure, and even affect the diagnosis or treatment.

Problems solved by technology

[0004] However, most of the commonly used plug-in units are carbon buckles, which are made of ABS plastic with carbon powder added and silver-plated and silver chloride coating. The thickness reaches 1.0mm (including protrusions, and the thickness reaches 3mm). After being fixed with the wire, The thickness of the electrode sheet is about 2.2mm. The size of the ECG electrode, especially the size of the newborn ECG electrode is small, no more than 3mm. The thickness of the carbon buckle is easy to cause the separation of the covering material of the ECG electrode sheet and the hydrogel. Separation from loads such as release PET, lifting of contact labels

In addition, the carbon buckle also increases the rigidity of the ECG electrode, which reduces the flexibility of the electrode and increases the probability of the electrode falling off, thus affecting the electrical monitoring effect

At the same time, the installation of carbon button electrodes usually requires a lot of pressure, which is potentially harmful to infants and young children, and the installation process is one more step
