Abstract

A defibrillator (100) comprises a main machine (110), an electrode holder (120), a first magnetic connector (130), an in-vitro electrode plate (140) and a second magnetic connector (150). The electrode holder (120) is arranged on one side face of the main machine (110); the first magnetic connector (130) is fixed on the electrode holder (120); the in-vitro electrode plate (140) is electrically connected with the main machine (110); the second magnetic connector (150) is fixed on the in-vitro electrode plate (140) and can be magnetically connected with the first magnetic connector (130). In the defibrillator (100) described above the first magnetic connector (130) is magnetically connected with the second magnetic connector (150), so that the in-vitro electrode plate (140) is fixed on the electrode holder (120) without the use of an elastic element such as an elastic fastener, thereby avoiding the situation where the clamping force decreases owing to the yielding of the elastic element after a long-term use. The in-vitro electrode plate (140) can be firmly fixed on the electrode holder (120). In addition, people can also readily fix or take off the in-vitro electrode plate (140) on/from the electrode holder (120), so that the demand for ease of use is met.

Description

Defibrillators

[Technical Field]

The utility model relates to medical equipment technology, in particular to a defibrillator.

【Background technique】

Cardiac DC cardioversion is an effective method for treating rapid ectopic arrhythmia with electrical energy and transforming it into sinus rhythm. The machine used for electrical cardioversion, also known as defibrillator, is the main device for performing electrical cardioversion.

External electrode plates are one of the commonly used attachments in defibrillation therapy. At present, the fixing method of the external electrode plate on the defibrillator is generally implemented in two ways:

The first type uses one side dead buckle and one side elastic buckle. In this solution, a dead buckle, or a stopper, is designed on one side of the external electrode plate mounting groove. One or more elastic snaps are designed on the other side. Before the panel is mounted on the defibrillator, the side is inserted obliquely into the dead buckle, and the other side is pressed under the elastic buckle to achieve the clamping.

The second type uses a double-sided elastic buckle to clamp. In this solution, one or more elastic cards are respectively designed on both sides of the external electrode plate mounting groove, so that the electrode plates can be directly inserted into the position.

In summary, for the conventional defibrillator, since it is engaged by elastic members such as elastic snaps, the clamping force caused by the yielding of the elastic members decreases with long-term use. If the clamping force of the elastic member is lowered, the fixing of the external electrode plate is affected.
