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).本發明係關於一種用於在一哺乳動物內部傳送一藥物(104)的電子藥錠(102)。該電子藥錠(102)包括一儲藥倉(106),該儲藥倉(106)用於回應於一預定義位準之壓力而釋放該藥物(104)。此外,包括一主要彈性元件(108),其用於在一活塞(110)從其約束位置釋放後經由該活塞(110)而將該預定義位準之壓力施加至該儲藥倉(106)。在處於約束位置時,該活塞(110)接著藉由使該主要彈性元件(108)相應變形而在該主要彈性元件(108)中引發一預定義位準之應力。該電子藥錠(102)包括一機構(114),該機構用於在致動後從將該活塞(110)維持在其約束位置之一約束組態變成釋放該活塞(110)的一釋放組態。在該等組態間之變化期間該機構(112)將該活塞(110)之位移限制在大體上小於該主要彈性元件(108)中所引入之該變形的一位準。(無元件符號說明)
