Abstract

A flexible container for storing a liquid medicament comprises a container wall consisting of two wall sheets of flexible material that are sealed together is disclosed. The container may comprise a storage compartment for the liquid medicament, and an access opening on one of the wall sheets. The storage compartment and the access opening may be in fluid connection. The access opening is designed to be fluidly connected to an outer conduit system. An insert part may be arranged between the two wall sheets with positive locking, and may fluidly connect the storage compartment and the access opening.

Claims

1. A flexible container for storing a liquid medicament and connection to an outer conduit system, said flexible container comprising:

a container wall consisting of two adjacent wall sheets of flexible material that are sealed together along a sealing rim;

a storage compartment for the liquid medicament;

an access opening comprises a hole arranged in one of the wall sheets, wherein the storage compartment and the access opening are in fluid connection, and the access opening is designed to be fluidly connected to the outer conduit system; and

an insert part that is provided entirely within the container and immobilized only by positive locking between the two adjacent wall sheets and the sealing rim of the wall sheets, and that defines an interior conduit system which fluidly connects the storage compartment and the hole of the access opening, said insert part having an essentially flat body that has an upper surface defining an opening to the interior conduit system, and wherein the hole of the access opening is arranged directly above the opening of the interior conduit system of the insert part.

2. The flexible container according to claim 1, wherein the insert part is arranged and positively locked in an access area of the container, which is separated from the storage compartment by a neck or constriction.

3. The flexible container according to claim 1, further comprising elements for at least one of positioning and fixating the flexible container in a connection device.

4. The flexible container according to claim 3, wherein the connection device is of an infusion pump device.

5. The flexible container according to claim 3, wherein the elements for at least one of positioning and fixating are two or more holes or grooves arranged in a sealed area of the container or in an area of the wall sheets outside of the sealed area that does not belong to the storage compartment.

6. The flexible container according to claim 1, further comprising a connection device for use in an infusion pump device, and which comprises two clamp parts that are adapted to at least one of positively and non-positively lock the flexible container, and to fluidly connect an access opening of the flexible container to a conduit system of the connection device.

7. The flexible container according to claim 6, wherein one of the clamp parts faces towards the access opening and comprises a sealing element that is adapted to fluidly connecting the conduit system of the connection device with the access opening of the flexible container.

8. The flexible container according to claim 6, wherein a surface of the clamp parts of the connection device is adapted to an exterior shape of the flexible container.

9. The flexible container according to claim 8, wherein the exterior shape is an access area of the container.

10. The flexible container according to claim 3, wherein the connection device comprises elements for at least one of positioning and fixating the flexible container which interact with the elements for at least one of positioning and fixating of the flexible container.

11. The flexible container according to claim 1 wherein the interior conduit system of the insert part has one or more drain channels that lead to an outer edge of the body, and an inner conduit opening toward the upper surface that leads to the access opening, and being fluidly connected to the one or more drain channels that lead to the outer edge of the body.

12. The flexible container according to claim 11 wherein the one or more drain channels are embodied as at least one of depressions arranged on a lower surface of the insert part, and tubular conduits arranged inside the body of the insert part.

13. The flexible container according to claim 11 further comprising one or more positioning elements adapted to positively locking the insert part in the flexible container.

14. A device for the automated release of a liquid medicament comprising at least one flexible container according to claim 1.
