Abstract

The invention relates to a medicament container for a liquid medicament, the medicament container comprising a bag with an outlet, the bag being compressible or shrinkable by subjection of at least a part of the medicament container to an energy source.

Claims

1. Medicament container for a liquid medicament, the medicament container comprising a bag with an outlet, the bag being compressible or shrinkable by subjection of at least a part of the medicament container to an energy source, characterized in that a rigid core is arranged in the bag.

2. Medicament container according to claim 1, characterized in that the bag is compressible or shrinkable by subjection of at least a part of the medicament container to a heat source.

3. Medicament container according to claim 1, characterized in that the bag consists of a heat shrink material being configured to shrink when subjected to heat (Q).

4. Medicament container according to claim 1, characterized in that an actor material is at least partially arranged around the bag, the actor material being configured to shrink when subjected to heat (Q).

5. Medicament container according to claim 4, characterized in that the actor material comprises several sections which may be heated separately.

6. Medicament container according to claim 1, characterized in that the rigid core is arranged in a longitudinal direction of the bag.

7. Medicament container according to claim 1, characterized in that the outlet comprises an interface for receiving a hollow injection needle.

8. Medicament container according to claim 4, characterized in that the actor material comprises a remote section, which is not in contact with the bag and which is arranged for being subjected to heat (Q).

9. Medicament container according to claim 1, characterized in that at least one drain channel is arranged in the rigid core in a manner to connect at least one opening on a surface of the rigid core to the outlet.

10. Medicament container according to claim 9, characterized in that the bag is subdivided into at least two consecutive bag chambers, wherein the rigid core comprises a respective segment for each bag chamber, each segment having at least one opening of the drain channel.

11. Medicament container according to claim 10, characterized in that each segment comprises a central bulge.

12. Medicament container according to claim 1, characterized in that at least one sensor is integrated in the rigid core.

13. Medicament container according to claim 1, characterized in that an energy store is integrated in the rigid core.

14. Medicament container according to claim 12, characterized in that an end of the rigid core opposite the outlet is arranged as an interface for exchanging data of the sensor and/or energy from the energy store between the medicament container and at least one external component.

15. Injection arrangement for delivering a liquid medicament comprising a medicament container according to claim 1 and a hollow needle for piercing a patient'"'"'s skin arranged at the outlet.

16. Injection arrangement according to claim 15, characterized in that a valve and a hollow needle for piercing a patient'"'"'s skin are arranged at the outlet.

17. Inhaler arrangement for delivering a liquid medicament comprising a medicament container according to claim 1.
