Due to the fact that the heating bag is arranged on the defibrillation electrode body, the defibrillation electrode can be heated before being used under the extreme environment (below 0 DEG C), the temperature of the defibrillation electrode can be close to the temperature of a human body when the defibrillation electrode is used, and the problem that a patient misses the optimal rescue time due to the fact that the defibrillation electrode cannot be used under the extreme environment is solved.

Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a defibrillator and a defibrillator. Background Art

[0002] If a patient spontaneously experiences two or more episodes of hemodynamically unstable ventricular tachycardia or ventricular fibrillation within a 24-hour period, separated by normal sinus rhythm, this indicates that the patient is experiencing a very dangerous cardiac event. These recurrent episodes of ventricular tachycardia and / or ventricular fibrillation require urgent cardioversion and defibrillation. This clinical syndrome is known as ventricular electrical storm or VT storm. Ventricular electrical storm can occur in a variety of patients with or without structural heart disease. Its most common cause is myocardial ischemia, and in these cases, acute myocardial infarction is a high-incidence cause of ventricular electrical storm.

[0003] During an electrical storm, prompt defibrillation and cardioversion are the primary measures to restore hemodynamic stability. Existing defibrillation electrodes cannot perform external defibrillation in extreme environments (below 0°C). If defibrillation electrodes cannot be used in extreme environments, patients may miss the optimal time for rescue. Utility Model Content

The defibrillation electrode body is electrically connected to a host device for external defibrillation; the heating pack is disposed on the defibrillation electrode body and is capable of generating heat through an exothermic process or exothermic reaction to heat the defibrillation electrode body.

[0006] In one embodiment, the heating pack includes a second packaging member and a chemical heating element, which is sealed inside the second packaging member; the chemical heating element is used to generate an exothermic reaction with oxygen after the second packaging member is torn open.

[0022] Please refer to Figure 1-4The present application provides a defibrillation electrode. The defibrillation electrode includes a defibrillation electrode body 10 and a heating pack 20. The defibrillation electrode body 10 is used to be electrically connected to a host device for external defibrillation. The heating pack 20 is provided on the defibrillation electrode body 10. The heating pack 20 can be provided directly on the defibrillation electrode body 10 or indirectly on the defibrillation electrode body 10. The heating pack 20 can generate heat through an exothermic process or an exothermic reaction to heat the defibrillation electrode body 10, that is, the heating pack 20 generates heat through an exothermic process in a chemical reaction to heat the defibrillation electrode body 10. The exothermic process refers to a physical change, and the exothermic reaction refers to a chemical change.

[0023] Since the defibrillation electrode body 10 of the present application is provided with a heating pack 20, the defibrillation electrode can be heated before use in extreme environments (below 0°C), and the temperature of the defibrillation electrode during use can be close to the temperature of the human body, thereby preventing the problem that the defibrillation electrode cannot be used in extreme environments and solving the problem that the defibrillation electrode cannot be used in extreme environments, causing the patient to miss the best rescue time. Moreover, the defibrillation electrode is heated to the human body, and the defibrillation electrode will be more comfortable and safer when used.

[0024] The defibrillation electrodes are further described below through specific embodiments:

[0025] like Figure 1-4 As shown, in one embodiment, the heating pack 20 includes a second package 23 and a chemical heating element. The chemical heating element is sealed inside the second package 23. The chemical heating element is used to react with oxygen to generate an exothermic reaction after the second package 23 is torn open. The heat generated by the exothermic reaction can heat the defibrillation electrode body 10. When using the heating pack 20 of this embodiment, the user only needs to tear open the second package 23 so that the chemical heating element inside the second package 23 contacts with oxygen to generate an exothermic reaction, and the defibrillation electrode body 10 can be rapidly heated. This method of starting the heating pack 20 to generate heat (tearing open the package) is relatively simple, and can rapidly heat the defibrillation electrode body 10 under extreme conditions. Among them, the chemical heating element may include reduced iron powder, carbon powder, vermiculite powder, salt and water, etc. The chemical heating element is not limited to the substances mentioned in this application, and can also be other substances that react with oxygen to generate an exothermic reaction.

[0026] In one embodiment, the second packaging member 23 is a non-woven bag. The non-woven bag can provide insulation, slowing the chemical reaction rate inside the bag and more efficiently transferring the heat generated inside the bag to the defibrillation electrode body 10.

[0027] like Figure 4As shown, in one embodiment, there are two heating packs 20, and the defibrillation electrode body 10 is in sheet form. One heating pack 20 is disposed on one side of the defibrillation electrode body 10, and the other heating pack 20 is disposed on the other side of the defibrillation electrode body 10. By providing heating packs 20 on both sides of the defibrillation electrode body 10, the heating rate of the defibrillation electrode body 10 can be increased, allowing the defibrillation electrode body 10 to heat up quickly even in extreme environments.

[0028] like Figure 3 and Figure 4 As shown, in one embodiment, the defibrillation electrode further includes a third packaging member, in which the defibrillation electrode body 10 and the heating pack 20 are both sealed. The third packaging bag 24 further prevents the chemical heating element within the second packaging member 23 from coming into contact with oxygen when the defibrillation electrode is not in use, thereby extending the life of the defibrillation electrode.

[0029] Please refer to Figure 3 and Figure 4 The defibrillation electrode further includes a fourth packaging bag 25. The defibrillation electrode body 10 is disposed inside the fourth packaging bag 25, and the heating pack 20 is disposed outside the fourth packaging bag 25. Providing the fourth packaging bag 25 outside the defibrillation electrode body 10 prevents the chemical substances in the heating pack 20 from contaminating the defibrillation electrode body 10.

[0030] The present application also provides a defibrillator, comprising a main unit and defibrillation electrodes. The defibrillation electrodes are electrically connected to the main unit. The defibrillation electrodes may have the same or similar structure and perform the same or similar functions as the defibrillation electrodes described in any of the above embodiments, and will not be further described herein.

[0031] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
