Electrode pads for cardioverter defibrillator

Abstract

The invention relates to a plate electrode of an electric cardioversion defibrillator. The plate electrode comprises a first plate electrode body and a second plate electrode body. The bottom surface of the first plate electrode body is fixedly connected with an insulating plate, the vertex of the arc of the first plate electrode body is electrically connected with a first connecting plate through an insulating wire, and a first insulating handle is fixedly connected with the vertex of the arc of the first plate electrode body and surrounds the insulating wire. The center of the second plate electrode body is electrically connected with a second connecting plate through an insulating wire, a second insulating handle is connected with the center of the top surface of the second plate electrode body and surrounds the insulating wire, and a second insulating plate is arranged on the upper surface of the second plate electrode body with the second insulating handle as the center. The plate electrode is innovated, only the small power 30 J is needed for cardioversion of auricular fibrillation and supraventricular tachycardia, injury to a patient is small, and recovery is fast.

Description

technical field [0001] The invention relates to an electrode plate of a cardioverter defibrillator. Background technique [0002] The cardioverter-defibrillator is equipped with two paddles for external and internal use. Internal use of electrical cardioverter defibrillator is used when direct cardiac defibrillation is required for cardiac surgery or open heart massage. It is equipped with proprietary small electrode plates, one of which is placed on the right ventricular surface; Placed at the apex of the heart, spray physiological saline on the surface of the heart, and the electrode plate is close to the wall of the ventricle; the existing external cardioverter defibrillator uses two rectangular parallelepiped electrodes of the same size (a rectangle with a cross-section of 10.5 cm × 9 cm) When using one of the electrode plates, place one of the electrode plates on the 2-3 intercostal space (bottom of the heart) at the right edge of the sternum, and the other electrode p...

Problems solved by technology

The disadvantage of this kind of external electrical cardioverter defibrillator is that it is large in size and has a large contact area with the chest wall; because the human body is columnar, and the surface of the electrode plate is straight, the combination with the chest wall is not tight enough; the secondary damage is large and the current loss is large ; and it is impossible to perform electrical cardioversion in the lying position and anteroposterior position. If the patient needs to perform electrical cardioversion in the anteroposterior position, he can only take the standing position, and this position is not conducive to the patient's anesthesia and other treatment before electrical cardioversion
