A bag assembly eg a urine leg bag 1 is formed of two sheets 10 and 11 welded together around their edge, and an inlet tube 2 of a soft, flexible material eg PVC with its end secured between the two sheets at one edge. To strengthen the inlet tube during the welding operation, a sleeve 4 of e.g. a stiffer PVC is inserted in the end of the tube. A flutter valve 5 may be assembled on the end of the tube so that it is held in place by the two sheets when welded together. An outlet tube 3 is joined to the bag 1 at an opposite edge. <IMAGE> |
