The drainage bag system further includes a receptacle bag of a foil or sheet material for emptying the urinary drainage bag and having a receptacle compartment for storing urine and a connector for providing a connection between the receptacle bag and the urinary drainage bag. The connector provides a second inlet constituting a receptacle inlet to the receptacle compartment when connected to the receptacle bag such that urine can flow into the receptacle compartment. ## Claims ### Claim 1 A drainage bag system for urinary collection, comprising: a urinary drainage bag including a drainage bag inlet configured to be fluidly coupled to a catheter, a drainage bag outlet, and an outlet valve configured for regulating a flow of urine through the drainage bag outlet; a receptacle bag configured for receiving urine from the drainage bag through the drainage bag outlet, the receptacle bag including a receptacle compartment configured for storing urine; a fluid-absorbent powder contained in the receptacle compartment; a connector defining a receptacle bag inlet and configured for fluidly coupling the drainage bag outlet to the receptacle compartment, so as to permit the flow of urine into the receptacle compartment from the drainage bag outlet; and a non-return receptacle valve configured for regulating the flow of urine through the receptacle bag inlet into the receptacle compartment, wherein the non-return receptacle valve is further configured for allowing fluid to flow only into the receptacle compartment, and for allowing the fluid-absorbent powder to be introduced through the receptacle bag inlet into the receptacle compartment. ### Claim 2 (depends on 1) The drainage bag system according to claim 1, wherein the connector comprises a first end configured as a male funnel for placement inside the drainage bag outlet. ### Claim 3 (depends on 1) The drainage bag system according to claim 1, wherein the connector comprises a Luer lock. ### Claim 4 (depends on 1) The drainage bag system according to claim 1, wherein the receptacle bag is formed by stretch blow molding a preform, further including the connector. ### Claim 5 (depends on 1) The drainage bag system according to claim 1, wherein receptacle bag comprises a first foil having a first plurality of edges and a second foil having a second plurality of edges, the first foil and the second foil being welded together proximate the first and second pluralities of edges, and wherein the connector is a separate component from the receptacle bag. ### Claim 6 (depends on 1) The drainage bag system according to claim 1, wherein the receptacle bag is made from a fibrous pulp material. ### Claim 7 (depends on 1) The drainage bag system according to claim 1, further comprising a hanger attached to the receptacle bag and configured for removably hanging the receptacle bag on the outlet valve of the drainage bag. ### Claim 8 (depends on 7) The drainage bag system according to claim 7, wherein the first end of the connector is detachable from the outlet of the drainage bag, the system further comprising a closure attached to the hanger and configured for closing the first end of the connector when the first end of the connector is detached from the drainage bag outlet. ### Claim 9 A receptacle bag for emptying a urinary drainage bag through a drainage bag outlet, the receptacle bag comprising: a receptacle compartment configured for receiving urine emptied from the urinary drainage bag through the drainage bag outlet; a fluid-absorbent powder contained in the receptacle compartment; a connector defining a receptacle bag inlet and configured for fluidly coupling the drainage bag outlet to the receptacle compartment, so as to permit the flow of urine into the receptacle compartment from the drainage bag outlet; and a non-return receptacle valve configured for regulating the flow of urine through the receptacle bag inlet, wherein the non-return receptacle valve is further configured for allowing fluid to flow only into the receptacle compartment through the receptacle bag inlet, and for allowing the fluid-absorbent powder to be introduced through the receptacle bag inlet into the receptacle compartment. ### Claim 10 (depends on 9) The receptacle bag according to claim 9, wherein the receptacle bag is formed by stretch blow molding a preform, further including the connector. ### Claim 11 (depends on 9) The receptacle bag according to claim 9, further comprising a first foil having a first plurality of edges, and a second foil having a second plurality of edges, wherein the first foil and the second foil are joined together proximate the first plurality of edges the second plurality of edges, and wherein the connector constitutes a separate component from the receptacle bag. ### Claim 12 (depends on 9) The receptacle bag according to claim 9, wherein the receptacle bag is made from a fibrous pulp material. ### Claim 13 (depends on 9) The receptacle bag according to claim 9, further comprising a hanger attached to the receptacle bag and configured for removably attaching the receptacle bag to the drainage bag. ### Claim 14 (depends on 13) The receptacle bag according to claim 13, wherein the first end of the connector is detachable from the drainage bag outlet, the system further comprising a closure attached to the hanger and configured for closing the first end of the connector when the first end of the connector is detached from the drainage bag outlet. ### Claim 15 A packaged receptacle bag, wherein the receptacle bag is configured for emptying a urinary drainage bag through a drainage bag outlet, the packaged receptacle bag comprising: a receptacle compartment configured for receiving urine emptied from a urinary drainage bag through a drainage bag outlet; a connector defining a receptacle bag inlet and configured for fluidly coupling the drainage bag outlet to the receptacle compartment, so as to permit the flow of urine into the receptacle compartment from the drainage bag outlet; and a non-return receptacle valve configured for regulating the flow of urine through the receptacle bag inlet, wherein the non-return receptacle valve is further configured for allowing the urine to flow only into the receptacle compartment through the receptacle bag inlet; and packaging containing the receptacle bag and having an openable portion defining, when opened, an opening configured for allowing the connector to extend out of the opening while the receptacle bag is inside the packaging, so as to permit a sterile connection to the urinary drainage bag. ### Claim 16 (depends on 15) The packaged receptacle bag according to claim 15, wherein the packaging comprises a mark indicating the openable portion such that the connector may be pulled out through the opening, the mark being located between a first side and a second side of the packaging, the receptacle bag placed in the packaging with the connector located between the first side and the second side and closer to the mark than to the first side or the second side. ### Claim 17 A drainage system for wound drainage, comprising: a receptacle bag configured for collecting liquid from a wound; and a tube configured to connect the receptacle bag to the wound; wherein the receptacle bag includes a receptacle compartment configured for storing the liquid and having a receptacle inlet, the receptacle inlet including a connector having a distal end defining a female funnel receiving the tube; and wherein the tube extends more than about 0.5 m between a first tube end and a second tube end, the first tube end defining a male funnel placed in the female funnel, and the second tube end comprising a male Luer lock fitting.
