Abstract

The invention relates to a swallowable medication capsule capableof dispensing fluid medicine stored in a medication compartmentthrough a valveless exit hole. A vent holeenables ventilation of an actuator cavitywhich houses an actuator used for displacing a surfacewhich separates the medication cavityand the actuator cavity. By locating the vent and exit holes close to each other so that contact with contracting parts of the gastrointestinal tract and the exterior surfaceis not able to prohibit a pressure passageway between the vent and exit holes, creation of a pressure difference of pressures in the medication and actuator cavity is prohibited.
