Translated fromGerman

Vorrichtung zum selbsttätigen Einstechen einer Injektionsnadel Essind Injektionsspritzen bekannt, die mit der Injektionsnadel durch Federkraft betätigtwerden. Auch sind schon Vorrichtungen vorgeschlagen worden, mittels deren die Nadeleiner Injektionsspritze sterilisiert und auf den Pumpenteil der Spritze steril aufgesetztwerden kann, ohne daß sie hierbei mit der Hand angefaßt wird.Device for the automatic insertion of an injection needle EsInjection syringes are known which are actuated by spring force with the injection needlewill. Devices have also been proposed by means of which the needlean injection syringe and placed sterile on the pump part of the syringewithout being touched by hand.

Im Gegensatz zu diesen Injektionsspritzen, bei denen die Nadel inVerbindung mit dem Spritzenkörper in den menschlichen Körper durch Federkraft odervon Hand eingeführt wird, liegt der Erfindung die Aufgabe zugrunde, ein Hilfsgerätzu schaffen, welches das subkutane Einstoßen einer Injektionsnadel für sich alleingetrennt von dem Spritzenkärper ermöglicht und auf diese Weise den Einstich derNadel rascher und damit auch schmerzloser auszuführen gestattet. In contrast to these hypodermic syringes, where the needle is inConnection with the syringe body in the human body by spring force oris introduced by hand, the object of the invention is to provide an auxiliary deviceto create, which is the subcutaneous thrusting of a hypodermic needle by itselfseparated from the syringe body and allows the puncture in this wayNeedle to be carried out more quickly and therefore more painlessly.

Diese Aufgabe wird durch eine Vorrichtung zum selbsttätigen Einstecheneiner Injektionsnadel erfindungsgemäß dadurch gelöst, daß die Injektionsnadel, getrenntvon der Injektionsspritze, auf einem als Schlagbolzen ausgebildeten Nadelträgeraufgesetzt und in an sich bekannter Weise durch Federkraft eingestochen wird. DiesesHilfsgerät weist dabei außer seiner äußerst einfachen und weitestgehend schmerzfreienAnwendung auch den Vorteil auf, daß es nicht wie die gebräuchlichen Injektionsspritzenlediglich für eine besondere Nadel, sondern für alle handelsüblichen Injektionsnadelnbenutzbar ist. This task is achieved by a device for automatic piercingan injection needle according to the invention in that the injection needle is separatedfrom the injection syringe, on a needle carrier designed as a firing pinis placed and pierced in a known manner by spring force. ThisAuxiliary device shows besides its extremely simple and largely painlessApplication also has the advantage that it is not like the common hypodermic syringesonly for a special needle, but for all commercially available injection needlesis usable.

Im einzelnen kann die Vorrichtung nach der Erfindung so ausgeführtwerden, daß die von der Federkraft bewirkte Verschiebung der Nadel durch einen elastischenAnschlag begrenzt wird, der als Ring den Nadelträger umschließt. Der Nadelträgersteckt fest in einer federbelasteten Spannhülse, die mit einer Muffe fest verbundenist. Ein in der Wandung des hohlen Handgriffes gelagerter Hebel wird durch eineFeder gegen die Muffe gedrückt. Der Hebel ist von Hand lösbar. In detail, the device according to the invention can be designed in this waybe that the displacement of the needle caused by the spring force by an elasticStop is limited, which surrounds the needle carrier as a ring. The needle carrieris stuck in a spring-loaded clamping sleeve, which is firmly connected to a sleeveis. A lever mounted in the wall of the hollow handle is activated by aSpring pressed against the sleeve. The lever can be released by hand.

Die Zeichnung veranschaulicht die Vorrichtung nach der Erfindung,die das selbsttätige Einstechen einer Injektionsnadel getrennt vom übrigen Körpereiner Injektionsspritze ermöglicht, in einer Ausführungsform im Längsschnitt. The drawing illustrates the device according to the invention,the automatic insertion of a hypodermic needle separately from the rest of the bodya syringe allows, in one embodiment in longitudinal section.

In einem als Handgriff dienenden länglichen Hohlzylinder 1 ist gleichachsigmittels einer Röhre 5 und eines am anderen Zylinderende vorgesehenen elastischenRinges 3 eine verschiebbare Spannhülse 2 geführt, die in ihrer Bohrung den Trägerstift7 für die nicht dargestellte Injektionsnadel aufnimmt. Eine mit der Spannhülse 2fest verbundene Muffe 9 steht unter der Einwirbrung einer auf dem oberen Ende derRöhre 5 abgestützten Schraubenfeder 4 welche die Spannhülse 2 wie einen Schlagbolzenaus dem Hand-griff 1 herausstößt, wenn ein in der Wandung des Handgriffes gelagerterHebel 6 mit der Hand betätigt wird. Durch eine Blattfeder 8 wird der Hebel 6 gegendie Muffe 9 gedrückt und dadurch die Feder 4 gespannt. Der Ring 3 wirkt als elastischerAnschlag für die Muffe 9 und begrenzt den Verschiebungsweg der Spannhülse 2 unddamit der Injektionsnadel. Der Auslösehebel 6 kann auch durch einen federbelastetenDruckknopf ersetzt sein. In an elongated hollow cylinder 1 serving as a handle is coaxialby means of a tube 5 and an elastic one provided at the other end of the cylinderRing 3 guided a displaceable clamping sleeve 2, the carrier pin in its bore7 receives for the injection needle, not shown. One with the adapter sleeve 2firmly connected sleeve 9 is under the influence of a on the upper end of theTube 5 supported coil spring 4 which the clamping sleeve 2 like a firing pinfrom the handhandle 1 protrudes when a stored in the wall of the handleLever 6 is operated by hand. The lever 6 is counteracted by a leaf spring 8the sleeve 9 is pressed and the spring 4 is thereby tensioned. The ring 3 acts as an elasticStop for the sleeve 9 and limits the displacement of the clamping sleeve 2 andthus the injection needle. The release lever 6 can also be spring-loadedButton replaced.

Die Vorrichtung wird wie folgt benutzt: Mit der normalen Spritzewird die medizinische Flüssigkeit der Ampulle entnommen. Die Injektionsnadel wirddann von der Spritze abgenommen und mit dem sterilen Trägerstift 7 verbunden, derin die Bohrung der Spannhülse 2 eingeschoben wird. Gleichzeitig wird die Vorrichtungdurch Einschieben der Hülse 2 in die Führungshülse 5 gespannt. Die Teile der Vorrichtungnehmen dann die aus der Zeichnung ersichtliche Stellung ein, in welcher die Spannhülse2 durch den Hebel 6 verriegelt ist. Durch Druck auf den Auslösehebel 6 erfolgt eindurch die Spannfeder 4 bedingtes schnelles und somit schmerzloses Eindringen derInjektionsnadel in den Körper. Die Vorrichtung wird nun von der Nadel, die im Körpersteckt, abgezogen. The device is used as follows: With the normal syringethe medical liquid is removed from the ampoule. The injection needle willthen removed from the syringe and connected to the sterile carrier pin 7, theis inserted into the bore of the adapter sleeve 2. At the same time the devicetensioned by pushing the sleeve 2 into the guide sleeve 5. The parts of the devicethen take the position shown in the drawing, in which the clamping sleeve2 is locked by lever 6. Pressing the release lever 6 causes adue to the tension spring 4, rapid and thus painless penetration of theInjection needle into the body. The device is now supported by the needle that is in the bodystuck, withdrawn.

Hierauf wird an die Nadel die normale Injektionsspritze angesetztund mit dieser die Injizierung ausgeführt.The normal injection syringe is then attached to the needleand with this the injection is carried out.
