Abstract: The catheter has a main channel which opens into the bladder and which is provided with a seal and, if appropriate, with an inflatable chamber which is arranged near the inner end and whose state of expansion can be controlled from the outside via a connecting channel. According to the invention, there is also formed in the catheter an additional supply channel which is accessible from the outside and which, with the catheter in the inserted state, opens into the urethra before the prostate gland and is used for supplying a medicinal treatment agent into the urethra. This supply channel in the most straightforward case has a single outlet opening, but it is expedient for the supply channel, in the area of its opening on the urethra side, to open into an annular channel which has a number of outlets distributed around the catheter periphery. In addition, or alternatively, it is also possible for the supply channel to be guided around the catheter periphery in a helical formation and to be provided with a number of outlets arranged at a distance from one another. <IMAGE>

Abstract: The fastener (18) has a first and a second strip-shaped closure part (20, 22) which bears on one side an adhesive layer (28 or 30). The second closure part (22) is constructed so as to be non-adhesive on its side opposite the adhesive layer (30). It is held by adhesion on its side having the adhesive layer (28) with its adhesive layer (30) at a distance from the one end face of the first closure part (20). A partial piece (26) of the first closure part (20) forms an attachment part for its attachment to another part of the disposable nappy (10).   An intermediate connection member (42) which adheres to the adhesive layer (28) of the first closure part (20) and to which the one end face of the second closure part (22) is bonded by its adhesive layer (30) serves for the mutual connection of the two closure parts (20, 22). By said mutual connection by means of the intermediate connection member (42), sufficient connection forces are achieved and it has been possible to reduce the length of the second closure part (22) to the dimension along which the closure part can be bonded completely to the nappy. Thus high-quality strip material is saved. <IMAGE>
