Abstract: Defibrillation devices provided embodiments of the present disclosure include a defibrillation component, a first processor, and a second processor. The defibrillation component performs a defibrillation task, the first processor acquires data from the defibrillation component and processes the data to obtain defibrillation data. The second processor acquires extension device data from an extension device. The second processor is connected with the first processor, and the second processor and the first processor are capable of transmitting preset information. In this defibrillation device, the defibrillation function is performed by the first processor, and the function of the extension device is performed by the second processor, such that the functional isolation between the defibrillation task and the extended task is achieved.
