Description
Verfahren zur Herstellung von nahtlosen Gummi-Okklusivpessaren Die Erfindung betrifft ein im Tauchverfahren nahtlos hergestelltes Okklusivpessar mit federndem Ring. Im Laufe der bisherigen Fabrikation ergab sich hierbei häufig der übelstand, daß die auch gleichzeitig die Haube bildende Gummimasse den Ring nicht völlig umschloß, sondern daß sich am Ring Löcher gebildet hatten, die der Luft und der Feuchtigkeit Zutritt gestatteten und das Pessar unbrauchbar machten. Um diesem Übelstande abzuhelfen, verfährt man nach vorliegender Erfindung so, daß man den federnden Ring (Federring, Spiralring, Uhrfeder) noch besonders mit Plattengummi umkleidet, so daß er in jedem Falle gegen außen völlig abgeschlossen ist. Dieser Plattengummibelag kann auch weiter reichen, als es eben nur zur Umkleidung des Ringes nötig ist, und sich auch mehr oder weniger weit in, den Haubenteil des Pessars erstrecken.Process for the manufacture of seamless rubber occlusive pessaries Die The invention relates to an occlusive pessary made seamlessly by the immersion process springy ring. In the course of the previous production, this often resulted in the The problem was that the rubber compound, which also forms the hood at the same time, does not form the ring completely enclosed, but that holes had formed on the ring, those of the air and allowed access to moisture and rendered the pessary unusable. To this To remedy inconveniences, one proceeds according to the present invention so that one the springy ring (spring ring, spiral ring, clock spring) especially with plate rubber so that it is completely closed off from the outside in any case. This Plate rubber covering can also go further than it is just to cover the ring is necessary, and also extend more or less far into the hood part of the pessary.
Der Erfindungsgegenstand ist beispielsweise in Abb. i und 2 in zwei Ausführungsformen im Querschnitt schematisch dargestellt, und zwar gibt Abb. i eine Ausführungsform, bei der die Plattengummiumkleidung i des Ringes 2 nur um diesen herum angebracht ist, während nach Abb.2 eine weiterreichende Plattengummiumkleidung 3 vorhanden ist, die eine gewisse Strecke weit m. die Haube q. hineinragt.The subject of the invention is for example in Fig. I and 2 in two Embodiments shown schematically in cross section, namely Fig. I is a Embodiment in which the plate rubber lining i of the ring 2 only around this is attached around, while according to Fig 3 is present, which is a certain distance m. The hood q. protrudes.
Die Umkleidung des Ringes mit Plattengummi findet erst dann statt, wenn die Pessarform fertig getaucht ist. Es wird der nahtlose Gummi auf der Pessarform mit Gummiplatte beklebt, und hierin wird dann der Ring eingerollt, so daß derselbe mit Platte und nahtlosem Gummi völlig umkleidet ist. Hiernach wird das Ganze vulkanisiert und durch diese Vulkanisation gleichzeitig eine feste Verbindung des nahtlosen Gummis mit dem Plattengummi erzielt.The ring is wrapped in rubber sheet only then when the pessary form has finished dipping. It becomes the seamless rubber on the pessary shape covered with rubber sheet, and then the ring is rolled up in this, so that the same is completely encased with plate and seamless rubber. Then the whole thing is vulcanized and through this vulcanization at the same time a firm connection of the seamless rubber achieved with the plate rubber.
