Types of Fall
The Vibby provides additional support to the manual pendant, by
adding automatic detection of heavy/dangerous falls to its wearer
when they are lying on the floor with or without activity and are
unable to recover to a standing position.
A heavy/dangerous fall is characterised by 4 steps:
1) An active person in an upright position followed by:
2) A quick and sudden loss of balance followed by:
3) A significant impact of the person with the floor followed by:
4) A lying position on the floor with or without activity of the person,
the wearer being unable to press the manual help button or recover
to a standing position after the fall.
If these four steps occur, then an automatic alarm to the Lifeline
home unit could be activated. *
*The fall detection technology in the Vibby does not allow analysis and
interpretation of all fall situations. Soft falls, slumping falls, descent controlled falls
against a wall or a chair, etc...are not be detected by the Vibby.
Considering the technology used and the target to minimise false alarms, all falls
even dangerous-heavy falls cannot be detected, for this reason whenever the user
needs assistance they should always press the help button on the Vibby.
