Description

Ih Nutiung des sogenannten Frankeschen Schnäppers mit fest eingebauter Lanzette ergab sich der Nachteil, daß die Lanzette schlecht steril zu halten ist. Durch diese schwierige Sterilhaltung wurde häufig der homologe Serumikterus übertragen. Zur Abwendung dieser Virusinfektion waren außergewöhnliche Zerlegungsarbeiten des Frankeschen Schnäppers nach jeder Benutzung erforderlich, die sich zeit- und untersuchungsmäßig nicht als regelmäßig durchführbar erwiesen. Aus diesem Grund wurde vielfach die weitere Benutzung des Frankeschen Schnäppers abgelehnt und zur Blutentnahme der Einstich mit einer gewöhnlichen Injektionskanüle aus der freien Hand, oft von Amts wegen, vorgeschrieben. Ih nutiing of the so-called Frankeschen snapper with built-in The disadvantage of a lancet was that it was difficult to keep the lancet sterile. Due to this difficult sterility maintenance, the homologous serum icterus was often transmitted. To prevent this virus infection, the Frankeschen Schnäppers required after each use, which changes in terms of time and examination not proven to be feasible on a regular basis. For this reason, the further use of the Frankescher Schnäpper refused and to take blood from the Penetration with a common injection needle from the free hand, often officially because of, prescribed.

Die Erfindung ist dadurch gekennzeichnet, daß der Vorteil des praktisch schmerzlosen Einschusses mit Frankeschem Schnäpper mit dem der allgemein bekannten und üblichen -Sterilhaltung der Inj ektionskanülen verbunden wird. The invention is characterized in that the advantage of being practical Painless bullet with the Frankish snapper with that of the generally known and the usual sterile maintenance of the injection cannulas.

In technischer Hinsicht hat der Schießbolzen 4 der Zeichnung des abgeändert entwickelten Apparates einen Aufsatzkonus 2 für die Injektionskanüle 5, der mit einem Griff das Aufsetzen oder Abnehmen der Stichkanüle 5 zur- Nutzung bzw. zur Reinigung und Sterilisierung ermöglicht. Um das Schußelementgewicht so weit zu mindern und den Anschlag des Schießbolzens in Entspannungsstellung zu mildern, zwecks Verhinderung des Abfliegens der Stichkanüle 5, ist eine Feder 1 entsprechender Stärke und Kraft angebracht, deren jeweilige Spannung in der zum Schuß geladenen (in zusammengedrückter) bzw. in der nach dem Schuß ausgelösten Stellung durch die Distanz der Schrauben -6 und 7 gegeben ist. n -ln der gespannten Stellung wird der Schießbolzen durch einen Fingerkipphebei 8 mit Einraster, der in clie etagenmäßig aufeinanderstehenden Einrastringe des Schießbolzens 9 je nach gewünschter Einschußintensität einzurasten ist, festgehalten. From a technical point of view, the firing pin 4 of the drawing of the modified apparatus developed an attachment cone 2 for the injection cannula 5, the attachment or removal of the puncture cannula 5 for use with one handle or for cleaning and sterilization. About the weft element weight like that to reduce far and to soften the stop of the firing pin in the relaxed position, for the purpose of preventing the puncture cannula 5 from flying off, a spring 1 is more appropriate Strength and power attached, their respective tension in the one charged to the shot (in the compressed position) or in the position released after the shot by the Distance between screws -6 and 7 is given. n -ln the cocked position is the Firing bolt by a fingerkip lever 8 with snap-in mechanism, which is level-wise one on top of the other locking rings of the firing pin 9 depending on the desired shot intensity is to be locked.

Nach Aufsetzen des Stichtiefenregulators 3 auf die Fingerkuppe ist der Schuß durch Fingerbetätigung des Fingerkipphebels auszulösen.After placing the stitch depth regulator 3 on the fingertip it is trigger the shot by pressing the finger on the rocker arm.
