Fall management bed pad

1. A sensor bed pad comprising:

a plurality of layers including a pair of outermost layers made of a flexible material, a pair of inner layers, each inner layer having an electrically conductive material thereon, and a central layer positioned between the pair of inner layers, wherein the inner layers are made of cloth, and wherein the central layer has a plurality of openings extending therethrough and wherein the inner layers are positioned such that the inner layers can move relative to one another and relative to the central layer, and wherein the pair of outermost layers entirely enclose the pair of inner layers and the central layer;

wherein the electrical conductive material of one of the inner layers contacts the electrical conductive material of the other inner layer through the openings in the central layer when a force is applied to the sensor bed pad to form an electrical conduction between the inner layers and complete an electrical circuit between the inner layers, and wherein one of the inner layers moves toward the other inner layer when such force is applied;

and wherein each of the inner layers includes a first zone positioned within a central region of each of the inner layers and a second zone positioned entirely along outermost, opposed lateral edges of the pad, and wherein each of the second zones has a U-shape that defines an interior region and wherein the respective first zone is entirely positioned within the interior region of the U-shape such that each of the second zones at least partially surrounds the respective first zone, and wherein each of the first and second zones contains a single electrical circuit line that spans a respective zone in a zig-zag pattern, and wherein a change in electrical indication from the respective first zone to the respective second zone indicates patient movement along the sensor bed pad.

2. The sensor bed pad of claim 1 , wherein at least one of the inner layers is at least partially made of the electrically conductive material.

3. The sensor bed pad of claim 1 wherein the electrically conductive material comprises an electrically conductive thread that is sewn onto the cloth of at least one of the inner layers.

4. The sensor bed pad of claim 3 , wherein the electrically conductive thread defines a circuit pattern formed of an elongated line having a first terminal end coupled to a wired or wireless connector and wherein the entire line is formed of the electrically conductive thread sewn onto the cloth of the at least one of the inner layers.

5. The sensor bed pad of claim 1 , further comprising a communication interface on the sensor bed pad.

6. The sensor bed pad of claim 5 , wherein the communication interface is a wireless interface.

7. The sensor bed pad of claim 5 , where the communication interface is a wired interface.

8. The sensor bed pad of claim 1 , wherein each of the entire second zones is rectangular.
