Problems solved by technology
However, due to the unavoidable impact of exercise on heart rate changes, the stimulation may be automatically turned on in the absence of epilepsy, which means that the false positive rate of epilepsy monitoring is high
This will not only increase the power consumption of the stimulator and reduce the service life of the stimulator (for rechargeable stimulators, the charging interval will be shortened), but also multiple high-dose stimulations caused by false positives may cause damage to the patient's nerves

The invention discloses an epilepsy monitoring device and a method for reducing the epilepsy monitoring false positive rate. The epilepsy monitoring device comprises an information collector, an information processor and a pulse generator; the information collector is used for collecting physiological signals and acceleration signals of a patient, and the physiological signals comprise body temperature signals and heart rate signals; the information processor analyzes and processes the acceleration signal and the body temperature signal to obtain motion state information of the patient, analyzes and processes the heart rate signal to obtain heart rate state information of the patient, and compares the motion state information and the heart rate state information with corresponding judgment threshold values; and whether an instruction for starting pulse stimulation is generated or not is judged according to the comparison result, the instruction is sent to the pulse generator, and the pulse generator starts pulse stimulation at a proper time according to the instruction. According to the epilepsy monitoring device, the pulse generator can start pulse stimulation as required, so that the energy consumption of the in-vivo implanted unit is further reduced.
Description
technical field [0001] The invention belongs to the medical field, and relates to an epilepsy monitoring device and a method for reducing the false positive rate of epilepsy monitoring. Background technique [0002] There are currently some vagus nerve stimulators that monitor changes in heart rate to predict seizures and deliver pulses of stimulation to weaken or directly relieve the threat of seizures. However, due to the unavoidable impact of exercise on heart rate changes, the stimulation may be automatically turned on in the absence of epilepsy, which means that the false positive rate of epilepsy monitoring is high. This will not only increase the power consumption of the stimulator and reduce the service life of the stimulator (for rechargeable stimulators, the charging interval will be shortened), but also multiple high-dose stimulations caused by false positives may cause damage to the patient's nerves. [0003] purpose of invention [0004] The purpose of the pr...
