Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung betrifft einen Katheter und bezweckt, die Vortheile des harten und des weichen Katheters mit einander zu verbinden. Zu diesem Zweck soll die Spitze, welche den gröfsten Theil der Katheterkrümmung bildet, weich sein, damit sie sich ihren Weg selbst sucht. Um aber mehr Gewalt anwenden zu können, als dies bei einem durchaus weichen Katheter möglich ist, soll der gerade Theil und ein kleines Anfangsstück der gekrümmten Spitze starr sein. Zu dem Ende wird, wie aus Fig. 1 ersichtlich, von einer gebogenen starren Röhre α, ζ. Β. einem starren Katheter, nach Entfernung der Spitze die Oeffnung durch Einbiegen des Randes leicht verengt. Durch diese Röhre α wird jetzt ein weicher Katheter b so weit hindurchgezogen, dafs die Spitze c aus der Röhre α herausragt.The present invention relates to a catheter and aims to combine the advantages of the hard and the soft catheter with one another. For this purpose the tip, which forms the greater part of the curve of the catheter, should be soft, so that it may find its own way. But in order to be able to use more force than is possible with a thoroughly soft catheter, the straight part and a small starting part of the curved tip should be rigid. At the end, as can be seen from Fig. 1, α, ζ of a bent rigid tube. Β. a rigid catheter, after removing the tip, the opening is slightly narrowed by bending the edge. A soft catheter b is now pulled through this tube α so far that the tip c protrudes from the tube α.

Die Einbiegung des Rarides verfolgt den doppelten Zweck, einestheils Verletzungen der Harnröhre beim Einführen des Katheters zu vermeiden und anderentheils infolge der Verengung dem weichen Katheter einen gewissen Halt zu bieten.The inflection of the Rarides has the dual purpose, on the one hand to injure the To avoid the urethra when inserting the catheter and partly because of the constriction to offer the soft catheter a certain support.

Fig. 2 zeigt den neuen Katheter in äufserer Ansicht.Fig. 2 shows the new catheter in an external view.

Der Katheter b wird in α mit Hülfe des in Fig. 3 dargestellten elastischen Stabes d mit stumpfer Spitze eingeführt, welche am oberen Ende eine kleine Handhabe e trägt, die gleichzeitig zur Orientirung dient, nach welcher Seite die leichte Biegung/ an der Spitze des Stabes gerichtet ist.The catheter b is introduced into α with the aid of the elastic rod d shown in Fig. 3 with a blunt tip, which carries a small handle e at the upper end, which also serves to orientate the side towards which the slight bend / at the tip of the rod is directed.
