Claim:
1. A magnetic induction pad with bed leaving sensing function, comprising: a deformation body, wherein the interior of the deformation body comprises a filling space that enable the deformation body to change the volume and size; wherein the filling space is in connection with the outside via at least one gas nozzle, the external of the deformation body comprises a first surface and a second surface; the first surface comprises a plurality of first bag bodies, and the second surface comprises a plurality of second bag bodies, wherein the plurality of first bag bodies are mutually arranged to form a first pattern, and the plurality of second bag bodies are mutually arranged to form a second pattern that is the same as the first pattern, so as to enable the position of each of the plurality of first bag bodies on the first surface to have a corresponding arrangement to each of the plurality of second bag bodies on the second surface; and a plurality of magnetic induction modules, wherein the plurality of magnetic induction modules comprise a group of magnetic members and a group of induction members, the group of magnetic members and the group of induction members are respectively arranged at the corresponding positions within the plurality of first bag bodies and the plurality of second bag bodies, and wherein the group of magnetic members and the group of induction members are used for sensing any changes in the distance of the first surface relative to the second surface.
