Description

Verfahren zur Sterilisierung von Catgutfäden Die bisherigen Verfahren, durch eine einmalige Sterilisation des fertiggedrehten, aber nicht vorbehandelten Catgutes mit .chemischen Mitteln, wie jodjodkaliumlösung, Joddampf, Sublimat, Formalin und anderen, keimfreies Catgut zu gewinnen, haben den Nachteil, daß keines der genannten Mittel mit genügender Wirkung in die fertigen Fäden einzudringen vermochte. Für eine wirksame Sterilisation war vielmehr die Vor behandlung der mechanisch gereinigten, aber nicht gedrehten Darmlamellen mit Antisepticis unbedingt erforderlich.Process for the sterilization of catgut threads The previous processes, through a one-time sterilization of the finished, but not pretreated Catgutes with chemical agents such as iodine potassium solution, iodine vapor, sublimate, formalin and others to gain aseptic catgut have the disadvantage that none of the above Agent was able to penetrate the finished threads with sufficient effect. For an effective sterilization was rather the pre-treatment of the mechanically cleaned, but not twisted intestinal lamellae with antisepticis absolutely necessary.

Das vorliegende neue Sterilisierungsverfahren geht von dem Gedanken aus, die Jodmischung durch Zusatz eines Beschleunigers derartig zu verstärken, daß dem Jod das Eindringen in die fertiggedrehten Catgutfäden ermöglicht wird, wodurch dann in einem Arbeitsgang die bekannte sterilisierende Wirkung des Jods eintritt, erheblich verstärkt durch die Hilfe des zugesetzten Beschleunigers.The present new sterilization method is based on the idea from strengthening the iodine mixture by adding an accelerator in such a way that the iodine is enabled to penetrate the finished twisted catgut threads, whereby then the well-known sterilizing effect of iodine occurs in one operation, considerably increased by the help of the added accelerator.

Es hat sich nun gezeigt, daß ein derartiger Beschleuniger von höchster Wirksamkeit in dem Jodmonochlorid gefunden ist.It has now been shown that such an accelerator is of the highest Effectiveness is found in the iodine monochloride.

Setzt man also einer in 8o % Alkohol gelösten Jodlösung geringe Mengen Jodmonochlorid hinzu, so ergibt sich, daß in dieser Lösung fertiggedrehte Catgutfäden schnell und sicher ganz gleichmäßig von dem Jod durchdrungen werden, wodurch nunmehr gleichzeitig eine schnelle und sichere Sterilisationswirkung in ganzen Catgutfäden erzielt wird, wie bakteriologische Nachprüfungen ergeben haben.So if you put small amounts of iodine solution dissolved in 80% alcohol If iodine monochloride is added, the result is that finished-twisted catgut threads are in this solution be penetrated quickly and safely evenly by the iodine, which now at the same time a fast and safe sterilization effect in whole catgut threads is achieved, as bacteriological tests have shown.

Behandelt man Catgut mit Jodalkohol, so ist nach den vorgenommenen Untersuchungen eine völlige Keimfreiheit mit den bisher angewandten Methoden nicht immer zu erzielen. Catgutknäule (= 3oom) in dieser Weise behandelt, waren zu 5o % unsteril. Zu denselben Ergebnissen führte ein weiterer Versuch mit Knäulen von im ganzen 120 m Fadenlänge und mit Kreuzen. Andere Untersuchungen in größerer Zahl zeigten ebenfalls, daß ein höherer Prozentsatz der Catgutfäden keine völlige Sterilität aufwies, wie dies auch zur Genüge bekannt ist.If catgut is treated with iodine alcohol, then according to the methods made Investigations do not guarantee complete sterility with the methods used so far always to be achieved. Catgut balls (= 3oom) treated in this way were 5o % non-sterile. Another experiment with balls of a total of 120 m thread length and with crosses. Other studies in large numbers also showed that a higher percentage of catgut sutures were not completely sterile exhibited, as is well known.

Keimfreiheit ist zu erzielen durch das neue Verfahren. Zu dem 10/0,) Jodalkohol, wie er bisher gebraucht wurde, wird jodmonochlorid im Verhältnis r : i ooo oder mehr hinzugefügt und dann auf das Catgutmaterial zur Einwirkung gebracht. Bei hinreichend langer Einwirkung - die Zeit ist abhängig von der Dicke der Fäden und schwankt zwischen 1 ¢ Tagen bis .4 Wochen -- werden alle Keime, auch Sporen vernichtet. Die Wirkung wird noch sicherer, wenn der Beschleuniger nach S- und 14tägiger Einwirkung erneuert wird, was bei großer Dicke des Fadens und des Knäuels erforderlich ist.Sterility can be achieved with the new process. To the 10/0,) Iodine alcohol, as it was previously used, becomes iodine monochloride in the ratio r: i ooo or more are added and then brought to act on the catgut material. With sufficiently long exposure - the time depends on the thickness of the threads and varies between 1 ¢ days to .4 weeks - all germs, including spores destroyed. The effect is even safer if the accelerator after S and 14 days The action is renewed, which is necessary if the thread and ball are thick is.

Es gelingt so z. B. größere Knäule, auch Catgut mit Erdsporen zu Fäden gedreht (z. B. 24X 10 m auf Glasstäben), durch Behandlung mit Jodalkohol unter zweimaligem Zusatz von odmonochlorid vollkommen keimfrei zu machen.It succeeds so z. B. larger balls, also catgut with earth spores to threads turned (e.g. 24X 10 m on glass rods), by treatment with iodine alcohol to make it completely sterile by adding odmonochloride twice.

Es ist also möglich, mit Zusatz des CILJ , Aktivators zu alkoholischer Jodlösung "äfe Wirkung des Jods so zu verstärken, daß in=* folge des: Eindringens des Jods in den Faden' bis an die Sporen heran eine völlige Durchdringung des Fadens und damit eine völlige Keimfreiheit zu erzielen ist. Diese Durchdringüngsfähigkeit des Aktivatorjods läßt sich auch nachweisen, wenn man diese auf dicke Catgutbäßsaiten (mit einem Durchmesser von o,5 cm) einwirken läßt. Es zeigte sich, daß selbst solche dicken Baßsaiten bis ins Innerste braun geworden waren und daß sie keimfrei zu machen sind. Der Vorzug dieses Verfahrens besteht außerdem darin, daß die zur e"rzielung der Keimfreiheit erforderliche Ein--ivi-rkungsdauer je nach der Menge und Dicke des Ausgangsstoffes herabgesetzt werden `kann.So it is possible, with the addition of the CILJ, activator to make it more alcoholic Iodine solution "should strengthen the effect of the iodine in such a way that in the consequence of: penetration of the iodine in the thread 'to the spores a complete penetration of the thread and thus a complete sterility can be achieved. This penetration ability of the activator iodine can also be detected if you place it on thick catgut bass strings (with a diameter of 0.5 cm) can act. It turned out that even such thick bass strings had turned brown to the core and that they had to be made sterile are. The advantage of this method is also that the to achieve The period of inducement required for sterility, depending on the quantity and thickness of the starting material can be reduced `.
