<p>A device to facilitate putting an elastic envelope (1) on a part projecting from a human body, e.g. putting a urinal drop collector onto a penis, consists of a casing (4) with two flexible side walls (5, 6) connected to each other along at least two of their side edges (5a, 6a; 5b, 6b) and with at least one opening (8) between two other side edges of the walls. The envelope is at least partially enclosed between the walls (5, 6) and its portion provided with an opening (2) is removably attached to said opening (8). By pressing the mutally connected side edges towards each other the opening (8) is enlarged between the walls, the opening of the envelope also being enlarged. The casing (4) is substantially flat when it is not used, and the space between it and the envelope (1) is airtight, whereby, when the opening (8) between the walls is extended, the portion of the envelope situated inside the casing is enlarged so that the envelope can be put onto said part of the human body. According to one method of expanding the cross section of the envelope, the casing is subjected to an actuating force causing expansion of the cross section of the casing (4) to a substantially oval or circular shape, thereby displacing the amount of air enclosed between the casing and the envelope from the space between the casing and envelope, so that the shape of the envelope conforms to that of the casing. A device according to an alternative embodiment includes a plastic tube at least partially surrounding the urinal drop collector (1) and having a first opening to which one end of the collector is sealingly and removably connected, and a second opening to which the portion of the collector intended for connecting to a urine collection bag is sealingly and removably connected. A means for evacuating the air enclosed in the space between the collector and tube can be connected to said space. When air is evacuated, the cross section of the collector is expanded so that it is pressed against the inside wall of the tube. </p> |
