Definitions

• the object of the present invention is to make available an instillation arrangement in which the aforementioned disadvantages have been eliminated, this being made possible in that the length of the tube is a fraction of the length of the urethra, or approximately one decimetre, in that the tube is executed along most of its length with an inflatable sac with elastic walls, which sac exhibits straight cylindrical form in its uninflated state and is so arranged, when in the 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 anchored to the aforementioned device and in the vicinity thereof is provided with a connection via which the sac can be inflated with and emptied of air, and in that the aforementioned device has a form which is adapted to the opening of the urethra and is executed in a previously disclosed manner with a connection to a vacuum source for the purpose of producing negative pressure at least in an area around the tube.
• connection 12 for a hypodermic syringe or similar which connection 12 is conveniently executed as a so—called Luer cone.
• Luer cone In Fig. 1 this connection is protected by a cover 13.
• the part 6c is executed as a thin— alled, generally tubular shell, the walls of which are thin and are made of a flexible material such as rubber.
• One end of the tubular part is in engagement by means of an internal bead 16 with a corresponding groove 17 arranged in the base part 6a, immediately above the connection 4, and approximately at its centre the tubular part 6c is so arranged as to engage with a projecting flange 18 running around the external periphery of the part 6b.
• the part 6c is otherwise executed in a similar manner to the device 6 illustrated in Fig. 1. Between the flange 18 and the bead 16 the parts 6b and 6c define a chamber 19 which communicates with a connection 10 for the purpose of its connection to a vacuum source.
