Electronic Pill for Delivery of Powder Medication

摘要

The invention relates to an electronic pill (102) for delivery of a medication (104) inside a mammal. The electronic pill (102) comprises a reservoir (106) for releasing the medication (104) in response to a predefined level of pressure. Furthermore a primary elastic element (108) is comprised for applying said predefined level of pressure to the reservoir (106) via a piston (110) upon release from the piston (110) of its constrained position. The piston (110) in its turn, when in constrained position, induces a predefined level of stress in the primary elastic element (108) by accordingly deforming it. The electronic pill (102) comprises a mechanism (114) for changing, upon actuation, from a constraining configuration in which the piston (110) is maintained at its constrained position to a releasing configuration in which the piston (110) is released. The mechanism (112) limits the displacement of the piston (110) during changing between said configurations to a level which is substantially smaller than the deformation introduced in the primary elastic element (108).

1. An electronic pill (102, 202) for delivery of a medication (104, 204) inside a mammal, comprising:
a reservoir (106, 206) configured for releasing the medication in response to a predefined level of pressure, a primary elastic element (108, 208) for applying said predefined level of pressure to the reservoir via a piston (110, 210) upon release from the piston of its constrained position, which piston, when in constrained position, is arranged for inducing a predefined level of stress in the primary elastic element by introducing an accompanying corresponding level of deformation therein, a mechanism (114, 214) configured for changing, upon actuation, from a constraining configuration which is arranged for maintaining the piston (110,210) in its constrained position to a releasing configuration which is arranged for releasing the piston from its constrained position, wherein the mechanism limits the displacement of the piston during changing from said constraining configuration to said releasing configuration to a level substantially smaller than the deformation introduced in the primary elastic element (108, 208).
