Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electrocardio, especially relates to a defibrillation electrode module and wearable defibrillator. BACKGROUND

[0002] At present, for heart disease patients, implanting a defibrillation device in the body is one of the main treatment methods, but the implantation of the defibrillation device in the body needs a complex cardiac surgery, and usually complications can occur; moreover, although it is an effective solution for patients with severe arrhythmia, it is not suitable for patients who are about to undergo a heart surgery or are in a recovery period after a heart surgery, because after the surgery is successful or recovered, the heart disease is basically eliminated, and there is no need to implant a defibrillation device in the patient's body. However, this stage is a dangerous period for the patient, and a heart disease can occur at any time. Traditionally, such patients need to be hospitalized for a long time, which not only has high treatment costs, but also has a great impact on the patient's quality of life. By using a wearable defibrillator, the wearable defibrillator is an automatic external defibrillator, which can partially replace the hospitalization treatment of the patient. When the patient is ill, the defibrillation of the heart is performed through discharge, that is, whether the patient is ill is determined by detecting the patient's electrocardio signal, and the disease can be eliminated or the symptoms can be relieved by passing a certain amount of current through the heart, so as to save time for the patient.

[0003] The wearable defibrillator comprises a defibrillation electrode module, a defibrillation host and a wearable body; the defibrillation electrode module comprises a defibrillation electrode sheet; the defibrillation host is electrically connected to the defibrillation electrode sheet through a cable, and most of the cable is arranged in the wearable body; when a heart disease occurs, the defibrillation host can control the defibrillation electrode sheet to output a certain amount of current to eliminate the disease or relieve the symptoms. At present, the cable is directly connected to the side or back of the defibrillation electrode sheet, and most of them are connected by welding; when the wearable defibrillator is worn, the cable can be pulled, which can cause the defibrillation electrode sheet to be poorly connected with the cable, or even fall off; in addition, when the defibrillation is completed, the defibrillation electrode sheet needs to be replaced, at which time the cable needs to be separated from the defibrillation electrode sheet; then the cable is connected to the new defibrillation electrode sheet; both disassembly and reconnection are very inconvenient.

[0025] As Figure 4 and Figure 5 shown, the defibrillation electrode module of the application includes defibrillation electrode piece 10 and cable 20; Reference Figures 1 to 3 , the defibrillation electrode piece 10 includes positive surface and back surface opposite to the positive surface, and two first side surfaces 11 oppositely arranged, and two second side surfaces 12 oppositely arranged;Among them: the part of one first side surface 11 extends to the upper part of the back surface to form a connecting component 3;Or a part of one second side surface 12 extends to the upper part of the back surface to form a connecting component 3. Preferably, the area of the first side surface 11 is less than the area of the second side surface 12, in other words, the length of the first side surface 11 is less than the length of the second side surface 12. The first end of the cable 20 is electrically connected with the connecting component 3, and the last end of the cable 20 is electrically connected with the defibrillation host computer.

[0026] Further, the defibrillation electrode piece 10 is a cuboid.
