Abstract
A device for placement in an environment, particularly a humid environment, for delivery of medication to said environment. The device comprises a reservoir (103) having an orifice (104), a conveying unit for conveying a reservoir's content (106) through the orifice (104) and an actuator arrangement for driving the conveying unit. In order to provide a reliable delivery of medication in a humid environment, the conveying unit comprises an auger (110) extending in the reservoir (103).
Claims19
A device comprising:
- a capsule adapted for placement into a patient's gastrointestinal tract;
- a reservoir in the capsule having an orifice;
- an auger rotatable about an axis and disposed at least partially in the reservoir for conveying contents of the reservoir through the orifice;
- a pressurizing member configured to pressurize the contents of the reservoir and that is movable relative to the auger;
- a first actuator configured to provide a force along the axis on the member;
- and
- a second actuator configured to rotate the auger.
