medical device to save our son from seizures

our son has Lennox Gastue Syndrome, he suffers daily with micro and full-blown seizures.  we have been trying to get his insurance to pay for a medical device that will monitor his brain activity, pulse, heart ,resp, as well as send an alarm to let us know when each time he has a seizure, especially during his sleep. this device will also help us to better track and monitor records of what we miss while we are out of the room, as well as being able to be continuous in treating this very bad syndrome. this epilepsy is the worst of them all and many have already died, so as a parent please help us to make life easier, happier and safer for our son.i will continue to do what's necessary for him and not let him suffer thank you to all and God Bless.
  P.S this device is made possible by the BRAIN SENTINAL LOCATED IN TEXAS, OUR SON REALLY NEEDS THIS  HELP  THIS DEVICE COST 5,000 A MONTH HE NEEDS 2 TO 3 MONTHS OF MONITOING
