transformed from a storage configuration to a use configuration. ### Claim 11 An assembly according to any of the preceding claims, wherein suction through the flow path is provided when the urine collecting bag is transformed from a storage configuration to a use configuration. ### Claim 12 An assembly according to any of the preceding claims claim, wherein the transformation of the urine collecting bag is a reshaping or unfolding of the urine collecting bag. ### Claim 13 An assembly according to any of the preceding claims, wherein the urinary draining device is connected to the inlet of the urine collecting bag and the connection comprises slideable connecting means so that the urinary draining device and the urine collecting bag are able to slide relative to each other. ### Claim 14 An assembly according to any of the preceding claims, wherein the flow promoting element is operated from the collapsed configuration to the expanded configuration in response to insertion of at least a part of the urinary drainage device through the inlet into the compartment. ### Claim 15 An assembly according to any of the preceding claims, wherein the expansion element has a flat shape in the collapsed configuration and transforms itself into a three-dimensional shape to define the expanded configuration. ### Claim 16 An assembly according to any of the preceding claims, wherein the suction means comprises an expansion element arranged in the collecting bag such that expansion of the expansion element causes increase of the volume of the bag and thereby suction through the flow path. ### Claim 17 An assembly according to any of the preceding claims, wherein the expansion element comprises an element with shape memory characteristics. ### Claim 18 An assembly according to any of the preceding claims, wherein the expansion element comprises a spring located in the bag. ### Claim 19 An assembly according to any of the preceding claims, wherein the expansion element is adapted to expand by contact with an expansion medium. ### Claim 20 An assembly according to any of the preceding claims, wherein the body of the flow promoting element is transformed into a helically coiled shape to define the expanded configuration. ### Claim 21 An assembly according to any of the preceding claims, wherein the flat shaped body comprises a spiral shaped body structure which
