    • 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).
    • 本发明涉及用于在哺乳动物内部递送药物(104)的电子药丸(102)。 电子药丸(102)包括用于响应于预定水平的压力释放药物(104)的贮存器(106)。 此外,主弹性元件(108)被包括用于在从其受限位置的活塞(110)释放时经由活塞(110)将所述预定水平的压力施加到储存器(106)。 当处于约束位置时,活塞(110)又通过相应地使其变形而在主弹性元件(108)中引起预定水平的应力。 电子药片(102)包括用于在致动时从其中将活塞(110)保持在其约束位置的约束构造改变为释放活塞(110)的释放构造的机构(114)。 所述机构(112)在所述构造之间的变化期间将活塞(110)的位移限制到基本上小于在主弹性元件(108)中引入的变形的水平。
