Problems solved by technology

The disadvantage of these systems is that they lack sufficient reliability
Additionally, these systems do not actually prevent falls, but only alert the user if they have already fallen

Embodiment Construction

[0024] figure 1 A system for preventing user falls is shown. Several sensors 2 are attached to a lower body segment 3, eg the user's legs. The sensor 2 is adapted to measure the movement of the lower body segment 3 and to convert said movement into a signal S. as in figure 2 As depicted in , the signal S of the sensor 2 is received by the controller 12 . The controller 12 converts the signal into the actual position sequence of the lower body segment 3 . In operation 100, said signal S is converted into an actual body position sequence. The actual sequence of body positions is then compared by the controller 12 to a predetermined sequence of body positions over time, wherein the predetermined sequence relates to a low or normal risk of falling for the user. The controller 12 is further adapted to determine that there is a high risk of falling when said actual sequence deviates to a certain extent from said predetermined sequence. A comparison of the actual sequence of p...

Abstract

System for fall prevention for a user, comprising a number of sensors (2) attachable to at least one lower body segment (3), wherein said sensors (2) are adapted to measure movement of said at least one lower body segment (3) and to translate the movement into a signal (S), the system further comprising a control (12) adapted to receive the signal (S) from said respective sensors (2), wherein in use the control (12) observes the signal (S) as an actual sequence of postures of said at least one lower body segment (3) and compares the actual sequence with a predetermined sequence of postures as a function of time, (the predetermined sequence relating to a low risk of falling,) wherein the control (12) is adapted to determine a high risk of falling when the actual sequence deviates from the predetermined sequence (to a certain degree). The invention further relates to a method for fall prevention using such a system for fall prevention.

Description

technical field [0001] The present invention relates to a system for preventing falls of a user. Background technique [0002] For fall prevention, and more specifically for fall detection, it is known to have a user wear an accelerometer, for example in a housing connected to the user's belt. The accelerometer triggers under high shock and / or free-fall acceleration. Additional parameters used to refine the triggering may be the detection level position and the duration of staying in said position after the accident. After an accident such as a fall, the accelerometer can send an alert to the service center, which will call the user back over the phone line and then decide what action to take to help the user. [0003] Furthermore, other fall detection systems are known. For example, the user may be provided with a panic button, typically worn on a cord around the user's neck. In the event of an accident such as a fall, the user can press the panic button, thereby alerti...
