Abstract

An arrangement for the instillation of fluids in a urethra comprising a tube of rigidity and diameter to be capable of being introduced into the urethra. The invention is characterized in that the length of the tube is a fraction of the length of the urethra, or approximately one decimeter. Along most of its length the tube is executed with an inflatable sac with elastic walls. This exhibits straight cylindrical form in its uninflated state, and in its inflated state has a slim, conical form, the base of which is situated at the end of the tube, and the tip of which is attached to a flange near the other end of the tube. Near the flange the sac has a connection via which the sac can be inflated with and emptied of air. The arrangement also comprises a device adapted to suit the opening of the urethra, made of an elastic material, and anchored to the flange. The device is executed with a connection leading to a vacuum source.
