Epileptic Seizure Monitor
Emfit Nocturnal Tonic-Clonic Seizure Monitor
This product's intended use is for monitoring a sleeping person who has risk of tonic-clonic seizures.
The alarm detects and distinguishes strong muscle jerkings such as tonic-clonic seizures from normal movements, but also presence and absence of micro-movements caused by person breathing and heart beating. So not only does it give notification to carer when the person has the clonic phase of a tonic-clonic seizure but also when the person leaves the bed (feature can be disabled).
Based on Unique, Proprietary Technology
The Emfit Nocturnal Tonic-Clonic Seizure Monitor consists of two main components - the bed sensor and the monitor.
The ultra thin and flexible but highly durable bed sensor (L-4060SL) is placed under he bed, and the monitor (D-1090-2G) with sophisticated embedded software and electronics by the bedside. These together detect the micro-movements of a person lying on bed - even heart beating and breathing, and the faster movements such as muscle jerkings when person has tonic-clonic seizure. There is no particular weight limits and system is sensitive enough also for small children.
When movements on the bed are faster than normal movements like turning, monitor detects this as clonic-phase of tonic-clonic epileptic seizure. The notification triggers if the faster movements continue longer than the preset delay. The delay can be set to 10, 13, 16 or 20 seconds.
The software allows the movements lower frequency threshold to be set to 3 Hz or 2 Hz. It is commonly known that with many epileptic seizures heart rate rises higher than normally in rest. With the lower 2 Hz setting it may be possible that the sudden rise in heart rate could be notified and monitor could possibly give notification of that alone. We have some users feedback of this but it has not been clinically evaluated yet. 2 Hz reflects to movements 120 times per minute ie. with that setting enabled it may be possible to notice if heart beat goes up to 120 beats or more.
A connecting wire is attached from the sensor to the control unit. The control unit can be placed next to the bed or on the wall using the included fastening bracket.The monitor is powered by 2 x batteries. (An optional, medical grade AC adapter is also available.)
The monitor has an audible alarm with adjustable volume and a dry-contact output for connection to wireless transmitter, nurse call system or carephone.
