Description

Zusammendrückbare Ampulle. Gegenstand des Patents 446 8 19 bildet eine zusammendrückbare Ampulle mit unter einer Schutzhaube befindlicher Injektionsnadel. Die Schutzhaube besteht aus dünnwandigem Material, so daß sie von der Injektionsnadel durchbohrt und die Injektion ausgeführt werden kann., ohne da.ß die Schutzhaube entfernt zu werden braucht.Squeezable ampoule. The subject of patent 446 8 19 forms a compressible ampoule with an injection needle located under a protective hood. The protective hood is made of thin-walled material so that the injection needle pierces it and the injection can be carried out without removing the protective hood.

Diese Vorrichtung hat den Nachteil, daß die Nadel und die Schutzhaube, welche beide verhältnismäßig weit aus dem Ampullenhals herausragen, Verletzungen ausgesetzt ist.This device has the disadvantage that the needle and the protective hood, both of which protrude relatively far from the neck of the ampoule, injuries is exposed.

Germ äß der vorliegenden Erfindung wird dieser Übelstand dadurch vermieden, daß. der Ainpullenhals verlängert ist, so daß die Stirnfläche der über der Nadel sitzenden Schutzhaube mit ihm abschneidet.According to the present invention, this drawback is avoided by that. the Ainpullenhals is elongated so that the face of the above the needle seated protective hood with him cuts off.

In der Zeichnung ist der Erfindungsgegenstand dargestellt. a ist die zusammendrückbare Ampulle mit dein Hals h. In diesem ist die Schutzhaube c so angeordnet, da.ß ihre Stirnfläche, die bei der Injektion von der Nadel b .durchbohrt wird, nicht aus dem Ampullenhals herausragt. Um der Nadel einen festeren Halt zu geben, ist im Ampullenhals ein Korkeau angeordnet, der als Führung für die Nadel dient. Der Hals k ist von einem Ring d umgeben, der die Wandung der Schutzhaube zwischen Ampullenhals und Korken festklemmt. Beim Gebrauch wird die Nadel durch Fingerdruck auf ihr hinteres verdicktes Ende nach vorn getrieben, so daß sie die Schutzhaube c durchbohrt.The subject of the invention is shown in the drawing. a is the squeezable ampoule with your neck h. In this the protective hood c is arranged in such a way that that their end face, which is pierced by the needle b. during the injection, is not protrudes from the neck of the ampoule. To give the needle a firmer hold is A corkeau is arranged in the neck of the ampoule, which serves as a guide for the needle. Of the Neck k is surrounded by a ring d, which is the wall of the protective hood between the ampoule neck and cork stuck. When in use, the needle is pushed back by finger pressure thickened end driven forward so that it pierces the protective hood c.

Für besondere Fälle, in denen eine Verstopfung der Hohlnadel zu befürchten ist, ist dEs hintere Ende derselben von einer Spiralfeder f umwunden, die mit einem kurzen Fortsatz g. in das hintere Nadelende, dieses verschließend, iineinragt. Beim Gebrauch wird wieder durch Fingerdruck die Nadel nach vorn getrieben. Damit drückt man gleichzeitig die Feder f zusammen, und der Fortsatz ä verbleibt zunächst in der hinteren Nadelöffnung, indem er mit nach vorn gleitet. Beim Nachlassen des Fingerdruckes sc"nnellt die Feder zurück und reißt den Fortsatz g; aus der Nadelöffnung heraus, so daß diese für den Zutritt der Eljektionsflüssigkeit frei wird.For special cases in which a blockage of the hollow needle is to be feared is, the rear end of the same is wound around by a spiral spring f, which is connected to a short process g. protrudes into the rear end of the needle, closing it. At the In use, the needle is pushed forward again by finger pressure. So that pushes the spring f together at the same time, and the extension ä initially remains in the rear needle opening by sliding forward with it. When the finger pressure is released the spring snaps back and tears the extension g; out of the needle opening, so that this is free for the access of the injection liquid.
