Abstract

A system (1) for generating a volume work which can be driven by a swellable substance, preferably for delivering a medicinal active compound, which comprises: a swellable substance chamber (13) filled with the swellable substance, a swelling agent reservoir (7) which can accommodate a swelling agent for swelling the swellable substance, and a fluidic transportation device (4) which can feed the swelling agent to the swellable substance from the swelling agent reservoir (7). The fluidic transportation device can be directly or indirectly electrically driven. A swelling agent dispenser (2) for feeding a swelling agent from the swelling agent reservoir (7) to a swellable substance cartridge (3) which can be connected to the swelling agent dispenser (2). Finally, a swellable substance cartridge (3) for performing a volume work, driven by a swellable substance, wherein the swellable substance cartridge (3) comprises the swellable substance chamber (13) filled with the swellable substance.

Claims

AMENDED CLAIMS received by the International Bureau on 20 February 2012 (20.02.2012)
1. System (1 ) for generating a volume work which can be driven by a swellable substance which system comprises:
a swellable substance chamber (13) filled with the swellable substance, a
swelling agent reservoir (7) which can accommodate a swelling agent for
swelling the swellable substance, and
a fiuidic transportation device (4) which can feed the swelling agent to the
swellable substance from the swelling agent reservoir (7), wherein
the fiuidic transportation device (4) can be directly or indirectly electrically
driven, characterized in that
a capillary stop is arranged in a fluid connection (9) for feeding the swelling
agent to the swellable substance.
2. System (1 ) according to claim 1 , characterized in that
the fiuidic transportation device (4) is a pump which is arranged downstream
of the swelling agent reservoir (7) in the direction of flow of the swelling agent
in order to deliver the swelling agent to the swellable substance from the
swelling agent reservoir (7).
3. System (1) according to one of the preceding claims, characterized in that
it comprises control means (5) in order to control the delivery rate of the fiuidic transportation device (4).
4. System (1 ) according to one of the preceding claims, characterized in that
the swellable substance chamber (13) is closed with a filter (15) which the
swellable substance essentially cannot overcome, but through which swelling
agent can be fed into the swellable substance chamber (13).
5. System (1 ) according to claim 4, characterized in that
the system (1 ) moreover comprises control means in order to counteract an
arching of the filter (15).
6. System (1 ) according to one of the preceding claims, characterized in that
the capillary stop comprises an air-filled chamber.
7. System (1 ) according to one of the preceding claims, characterized in that the system (1 ) comprises a swelling agent dispenser (2) and a swellable substance cartridge (3), wherein the swelling agent dispenser has electrical means for driving the fluidic transportation device (4) and the swellable substance cartridge (3) contains the swellable substance chamber (13) filled with swellable substance.
8. System (1 ) according to claim 7, characterized in that
the swelling agent dispenser (2) moreover comprises the fluidic transportation device (4) for transporting the swelling agent to a swelling agent release point (10) of the swelling agent dispenser (2).
9. System (1 ) according to claim 8, characterized in that
the swelling agent dispenser (2) comprises fixing means (11 , 12) in order to connect the swellable substance cartridge (3) to the swelling agent dispenser (2) such that the swellable substance cartridge (3) can absorb the swelling agent released at the release point (10).
10. System (1 ) according to claim 7, characterized in that
the swellable substance cartridge (3) contains the fluidic transportation device (4).
11. System (1 ) according to one of claims 7 to 10, characterized in that the swelling agent dispenser (2) moreover contains the swelling agent reservoir (7).
12. System (1 ) according to one of claims 7 to 10, characterized in that the swellable substance cartridge (3) contains the swelling agent reservoir (7).
13. System (1 ) according to one of claims 7 to 12, characterized in that the swellable substance cartridge (3) comprises an active compound chamber (18) which cooperates with the swellable substance chamber (13) such that an increase in volume of the swellable substance chamber (13) leads to a decrease in volume of the active compound chamber (18).
14. System (1 ) according to one of the preceding claims, characterized in that it is equipped with a level sensor.
15. System (1 ) according to one of the preceding claims, characterized in that it is for delivering a medical active compound.
16. Swelling agent dispenser (2) for feeding a swelling agent from a swelling agent reservoir (7) to a swellable substance cartridge (3) which can be connected to the swelling agent dispenser (2), wherein the swelling agent dispenser (2) comprises electrical means for electrical driving of a fluidic transportation device (4), characterized in that
a capillary stop is arranged in a fluid connection (9) for feeding the swelling
agent to the swellable substance.
