Description
Vorrichtung zum selbsttätigen Einstechen einer Injektionsnadel Es sind Injektionsspritzen bekannt, die mit der Injektionsnadel durch Federkraft betätigt werden. Auch sind schon Vorrichtungen vorgeschlagen worden, mittels deren die Nadel einer Injektionsspritze sterilisiert und auf den Pumpenteil der Spritze steril aufgesetzt werden kann, ohne daß sie hierbei mit der Hand angefaßt wird.Device for the automatic insertion of an injection needle Es Injection syringes are known which are actuated by spring force with the injection needle will. Devices have also been proposed by means of which the needle an injection syringe and placed sterile on the pump part of the syringe without being touched by hand.
Im Gegensatz zu diesen Injektionsspritzen, bei denen die Nadel in Verbindung mit dem Spritzenkörper in den menschlichen Körper durch Federkraft oder von Hand eingeführt wird, liegt der Erfindung die Aufgabe zugrunde, ein Hilfsgerät zu schaffen, welches das subkutane Einstoßen einer Injektionsnadel für sich allein getrennt von dem Spritzenkärper ermöglicht und auf diese Weise den Einstich der Nadel rascher und damit auch schmerzloser auszuführen gestattet. In contrast to these hypodermic syringes, where the needle is in Connection with the syringe body in the human body by spring force or is introduced by hand, the object of the invention is to provide an auxiliary device to create, which is the subcutaneous thrusting of a hypodermic needle by itself separated from the syringe body and allows the puncture in this way Needle to be carried out more quickly and therefore more painlessly.
Diese Aufgabe wird durch eine Vorrichtung zum selbsttätigen Einstechen einer Injektionsnadel erfindungsgemäß dadurch gelöst, daß die Injektionsnadel, getrennt von der Injektionsspritze, auf einem als Schlagbolzen ausgebildeten Nadelträger aufgesetzt und in an sich bekannter Weise durch Federkraft eingestochen wird. Dieses Hilfsgerät weist dabei außer seiner äußerst einfachen und weitestgehend schmerzfreien Anwendung auch den Vorteil auf, daß es nicht wie die gebräuchlichen Injektionsspritzen lediglich für eine besondere Nadel, sondern für alle handelsüblichen Injektionsnadeln benutzbar ist. This task is achieved by a device for automatic piercing an injection needle according to the invention in that the injection needle is separated from the injection syringe, on a needle carrier designed as a firing pin is placed and pierced in a known manner by spring force. This Auxiliary device shows besides its extremely simple and largely painless Application also has the advantage that it is not like the common hypodermic syringes only for a special needle, but for all commercially available injection needles is usable.
Im einzelnen kann die Vorrichtung nach der Erfindung so ausgeführt werden, daß die von der Federkraft bewirkte Verschiebung der Nadel durch einen elastischen Anschlag begrenzt wird, der als Ring den Nadelträger umschließt. Der Nadelträger steckt fest in einer federbelasteten Spannhülse, die mit einer Muffe fest verbunden ist. Ein in der Wandung des hohlen Handgriffes gelagerter Hebel wird durch eine Feder gegen die Muffe gedrückt. Der Hebel ist von Hand lösbar. In detail, the device according to the invention can be designed in this way be that the displacement of the needle caused by the spring force by an elastic Stop is limited, which surrounds the needle carrier as a ring. The needle carrier is stuck in a spring-loaded clamping sleeve, which is firmly connected to a sleeve is. A lever mounted in the wall of the hollow handle is activated by a Spring 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 Körper einer 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 body a syringe allows, in one embodiment in longitudinal section.
In einem als Handgriff dienenden länglichen Hohlzylinder 1 ist gleichachsig mittels einer Röhre 5 und eines am anderen Zylinderende vorgesehenen elastischen Ringes 3 eine verschiebbare Spannhülse 2 geführt, die in ihrer Bohrung den Trägerstift 7 für die nicht dargestellte Injektionsnadel aufnimmt. Eine mit der Spannhülse 2 fest verbundene Muffe 9 steht unter der Einwirbrung einer auf dem oberen Ende der Röhre 5 abgestützten Schraubenfeder 4 welche die Spannhülse 2 wie einen Schlagbolzen aus dem Hand- griff 1 herausstößt, wenn ein in der Wandung des Handgriffes gelagerter Hebel 6 mit der Hand betätigt wird. Durch eine Blattfeder 8 wird der Hebel 6 gegen die Muffe 9 gedrückt und dadurch die Feder 4 gespannt. Der Ring 3 wirkt als elastischer Anschlag für die Muffe 9 und begrenzt den Verschiebungsweg der Spannhülse 2 und damit der Injektionsnadel. Der Auslösehebel 6 kann auch durch einen federbelasteten Druckknopf ersetzt sein. In an elongated hollow cylinder 1 serving as a handle is coaxial by means of a tube 5 and an elastic one provided at the other end of the cylinder Ring 3 guided a displaceable clamping sleeve 2, the carrier pin in its bore 7 receives for the injection needle, not shown. One with the adapter sleeve 2 firmly connected sleeve 9 is under the influence of a on the upper end of the Tube 5 supported coil spring 4 which the clamping sleeve 2 like a firing pin from the hand handle 1 protrudes when a stored in the wall of the handle Lever 6 is operated by hand. The lever 6 is counteracted by a leaf spring 8 the sleeve 9 is pressed and the spring 4 is thereby tensioned. The ring 3 acts as an elastic Stop for the sleeve 9 and limits the displacement of the clamping sleeve 2 and thus the injection needle. The release lever 6 can also be spring-loaded Button replaced.
Die Vorrichtung wird wie folgt benutzt: Mit der normalen Spritze wird die medizinische Flüssigkeit der Ampulle entnommen. Die Injektionsnadel wird dann von der Spritze abgenommen und mit dem sterilen Trägerstift 7 verbunden, der in die Bohrung der Spannhülse 2 eingeschoben wird. Gleichzeitig wird die Vorrichtung durch Einschieben der Hülse 2 in die Führungshülse 5 gespannt. Die Teile der Vorrichtung nehmen dann die aus der Zeichnung ersichtliche Stellung ein, in welcher die Spannhülse 2 durch den Hebel 6 verriegelt ist. Durch Druck auf den Auslösehebel 6 erfolgt ein durch die Spannfeder 4 bedingtes schnelles und somit schmerzloses Eindringen der Injektionsnadel in den Körper. Die Vorrichtung wird nun von der Nadel, die im Körper steckt, abgezogen. The device is used as follows: With the normal syringe the medical liquid is removed from the ampoule. The injection needle will then removed from the syringe and connected to the sterile carrier pin 7, the is inserted into the bore of the adapter sleeve 2. At the same time the device tensioned by pushing the sleeve 2 into the guide sleeve 5. The parts of the device then take the position shown in the drawing, in which the clamping sleeve 2 is locked by lever 6. Pressing the release lever 6 causes a due to the tension spring 4, rapid and thus painless penetration of the Injection needle into the body. The device is now supported by the needle that is in the body stuck, withdrawn.
Hierauf wird an die Nadel die normale Injektionsspritze angesetzt und mit dieser die Injizierung ausgeführt.The normal injection syringe is then attached to the needle and with this the injection is carried out.
