<p>Vacuum tube (5) with separate clamping ring (7) , having an air chamber for generation and maintenance of an erection, which is applied before vacuation, having an expandable and contractible air chamber, with a groove in which a flat ring fits, which ring is part of a stretchable material with which the end of the vacuum tube is covered. The air chamber can be shrunk by means of under pressure and expanded by means of an over pressure. The matching air pump (11) can be chosen to function according to the principle of a syringe, in which case the neutral position can be varied by means of the initial amount of air in the air pump which works according to this principle. The insertion of the penis and the removal of the pressure ring can be carried out without problems. The transfer of the pressure ring is avoided. The obturation between the body and the instrument is perfect. Ejaculation is possible and the clamping pressure and size of the air chamber are controllable in a gradual manner .</p> |
