Emfit - Sensing what matters

The Emfit tonic-clonic seizure monitor consists of two main components. Flexible and durable bed sensor (L-4060SL) placed under mattress and a bed-side monitor (D-1090-2G) with sophisticated embedded software. These together detect the micro-movements of a person lying on bed - even heart beating and breathing, and the faster movements such as muscle spasms when person has tonic-clonic seizure. There is no particular weight limits and system is sensitive enough also for small children.

The control unit can be placed next to the bed or on the wall using the included fastening bracket. New 2nd generation monitor is now operated with 2 pcs AA size 1,5 V batteries. An optional, medical grade AC adapter is also available.

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.

In the summer 2008 released 2nd generation monitor the software allows the movements lower frequency threshold to be set to 3 Hz or 2 Hz. It is quite 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.

The monitor has an audible alarm with adjustable volume and a dry-contact output (NO and NC) for connection to wireless transmitter, nurse call system or carephone.

Emfit Nocturnal Tonic-Clonic Seizure Monitor (device model D-1090-2G and bed sensor model L-4060SL) is a Class 1 Medical Device. It complies with the essential requirements of EMC directive 2004/108/EC, CE mark directive 93/68/EEC and Medical Device Directive 93/42/EC and carries the CE marking accordingly.
