Description
Pessar Bisher verwendete man als Einlage für den Pessarrand eine einfache oder in mehreren Lagen übereinandergewickelte Bandfeder, welche den Zweck hat, das Pessar festzuhalten und am Rand das Durchdringen von Flüssigkeiten zu verhindern: Die Band- oder Uhrfedern hatten den Mangel, daß sie leicht zerbrachen und dann durch die spitzen Bruch-. enden Verletzungen verursachen konnten. Als Verbesserung verwendete man späterhin eine Spiralfeder, welche dem Brechen nicht ausgesetzt ist und auch einen weicheren Druck ausübt. Die Spiralfeder hat Jedoch den großen Mangel, daß sie die Neigung hat, sich in Form einer 8 zusammenzubiegen, In diesem Fall ist natürlich der verlangte Schutz nicht mehr vorhanden.Pessary So far, a simple insert has been used as an insert for the edge of the pessary or a ribbon spring wound in several layers on top of one another, which has the purpose of To hold the pessary firmly and to prevent liquids from penetrating at the edge: The band or clock springs had the problem that they broke easily and then through the pointed fracture. could cause injuries. Used as an improvement one later a coil spring, which is not exposed to breaking and also exerts a softer pressure. The coil spring, however, has the great shortcoming that it has a tendency to bend in the shape of an 8, in which case it is natural the required protection no longer exists.
Um die Bruchgefahr. der Uhrfedern zu beseitigen, wird als Gegenstand -der vorliegenden Erfindung eine Spiralfeder verwendet; deren Windungen in länglichem Querschnitt. gehalten sind und im Innern dieser Windungen eine oder mehrere Uhrfedern führt. Der Vorteil der Anordnung ist nicht nur die Vermeidung der Bruchgefahr der Bandfeder durch die gleichzeitige Verbindung mit einer Spiralfeder, welch letztere den Austritt von spitzen Bruchenden verhindert, sondern auch die Möglichkeit, die Auflagefläche des federnden Randes gegenüber der früher verwendeten Spiralfeder zu verbreitern und dadurch die Druckwirkung auf die empfindlichen Scheidenschleimhäute zu verringern.About the risk of breakage. to eliminate the watch springs, is as an object - the present invention uses a spiral spring; their turns in an elongated cross-section. are held and inside these turns leads one or more clock springs. The advantage of the arrangement is not only the avoidance of the risk of breakage of the coil spring through the simultaneous connection with a spiral spring, which the latter prevents the emergence of sharp broken ends, but also the possibility of widening the contact surface of the resilient edge compared to the spiral spring used previously and thereby the Reduce pressure on the sensitive vaginal mucous membranes.
Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt: Fig. i einen Querschnitt, Fig.2 einen Grundriß der in mehreren Lagen übereinandergewickelten Bandfeder. Die Bandfeder für den P.essarrandP ist in mehreren Lagen cl, c-, e3 übereinandergewikkelt und von einer Spiralfeder a umgeben; letztere hat zweckmäßig länglichen Querschnitt.The subject of the invention is shown in the drawing, namely shows: FIG. 1 a cross section, FIG. 2 a plan view of the layers wound one on top of the other Ribbon spring. The ribbon spring for the P.essarrandP is wound in several layers cl, c-, e3 on top of each other and surrounded by a spiral spring a; the latter has an expediently elongated cross-section.
