Wearable epilepsy monitoring device and system

The invention relates to a wearable epilepsy monitoring device and system. The wearable epilepsy monitoring device comprises a gravity sensing device for measuring movement change of limbs of a patient, a data acquiring device connected with the gravity sensing device and used for acquiring movement data recorded by the gravity sensing device and transmitting the movement data to a central processing device, the central processing device connected with the data acquiring device and used for processing acquired movement data, a data transmitting device connected with the central processing device and used for storing and transmitting the movement data, an alarm device connected with the central processing device and used for giving out an alarm signal during epileptic seizure of the patient, and a wireless transmitting device respectively connected with the data transmitting device and the alarm device and used for transmitting the alarm signal. When the patient wears the wearable epilepsy monitoring device, the movement change of the limbs of the patient can be measured through the gravity sensing device in real time, and 24-hour monitoring and recording of the epileptic seizure can be achieved.
