An arrangement for the instillation of fluids in a urethra comprising a tube (1) of appropriate rigidity and diameter to be capable of being introduced into the urethra. The invention is characterized in that the length of the tube (1) is a fraction of the length of the urethra, or approximately one decimetre. Along most of its length the tube (1) is executed with an inflatable sac (2) with elastic walls. This exhibits straight cylindrical form in its uninflated state, and is so arranged, when in its inflated state, as to adopt a slim, conical form, the base of which is situated at the end of the tube which is intended to be introduced, and the tip of which is attached to a flange (3) arranged close to the other end of the tube (1). In the vicinity of the flange the sac (2) is provided with a connection (4), via which the sac (2) can be inflated with and emptied of air. The arrangement also comprises a device (6) made of an elastic material anchored to the flange (3), the form of which device is adapted to suit the opening of the urethra. The device (6) is executed with a connection (10) leading to a vacuum source for the purpose of producing negative pressure at least in an area around the tube (1). |
