Abstract:
1. A device for monitoring the condition of a person, comprising: a casing; electronic circuitry; and at least one secure attachment mechanism, each comprising a first member which is capable of moving in a forward direction up to a locking state, at which the first member is interlocked by at least one second member, so that said first member cannot be moved backward by applying a first backward force, unless said interlock is unlocked by applying at least one second force independent of said first force, and wherein said first member is a spike, having at least one recess, and wherein at said locking state said second member is introduced into said recess, thereby preventing said spike from moving backward; and wherein: A. said second member is a socket member having a flat surface with an opening which is large enough for said spike to pass though; B. said socket member is capable of moving so that its flat surface coincides with a virtual plane which is perpendicular to said forward direction; C. said socket member, when at rest is so positioned, by means of an elastic member that applies to it a biasing force, to enable a tip of said spike to enter through said opening while said spike moves forward, and wherein said socket member prevents backward movement of said spike at the locking state; D. said spike is positioned such that during moving forward, a diagonal portion of said spike gradually pushes said socket member against said biasing force, up to said locking state, at which said biasing force pushes the socket member into said recess; E. an edge of said recess, facing said socket member at said locking state, is substantially perpendicular to said backward direction; and F. said second force is required for retracting said socket member out of said recess, against said biasing force.
