Gegenstand der vorliegenden Erfindung ist ein Flüssigkeitsbehälter für ärztliche Zwecke, aus dem das luftdicht in demselben eingeschlossene Medikament unter dem Druck eines in dem Behälter gleichfalls eingeschlossenen expandirenden Gases in die Stichwunde eingeführt wird, wobei die Injectionsnadel nach Entfernen einer Schutzhülle unmittelbar in das halsartige, durch ein Ventil sich selbsttätig verschliefsende Ende des Behälters eingeführt wird, zum Zweck, jegliche Infection zu vermeiden. The subject of the present invention is a liquid container for medical purposes, from which the airtight medication enclosed in the same under the pressure of a The expanding gas also enclosed in the container is introduced into the puncture wound is, the injection needle after removing a protective cover directly into the neck-like, automatically closing by a valve end of the container introduced is used for the purpose of avoiding any infection.
Bei den bisherigen Vorrichtungen war eine Einführung des Medikamentes unmittelbar aus dem Originalbehälter, wie er aus dem Laboratorium herauskam, ohne Hinzutritt von Luft oder Abfüllung in andere Gefäfse, Durchlaufen von Glas- oder Gummiröhrchen oder Einsaugen in Injectionsspritzen u. dergl., in den menschlichen Körper unmöglich.With the previous devices, the introduction of the drug was immediately off the original container as it came out of the laboratory, without the addition of air or filling into other vessels, passing through glass or rubber tubes or suction In injection syringes and the like, in the human Body impossible.
Alle diese Möglichkeiten und die nur allzuhäufige Gelegenheit zur Aufnahme von Krankheitskeimen werden bei Anwendung eines derartigen Behälters gemäfs vorliegender Erfindung vermieden.All of these possibilities and the all-too-common opportunity for germ ingestion are avoided when using such a container according to the present invention.
In der beiliegenden Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the accompanying drawing.
Fig. ι zeigt einen fertiggestellten und gefüllten Flüssigkeitsbehälter im Längsschnitt,Fig. Ι shows a completed and filled Liquid container in longitudinal section,
Fig. 2 einen Theil desselben im Gebrauchszustande, Fig. 2 shows a part of the same in the state of use,
Fig. 3 ist eine Injectionsnadel im Längsschnitt.Fig. 3 is an injection needle in longitudinal section.
Der aus Glas oder anderem geeigneten Material bestehende Flüssigkeitsbehälter α wird theilweise mit dem Medikament b gefüllt, in den freien Raum aber keimfreie Luft oder irgend ein geeignetes Gas unter einem gewissen Druck eingeführt. Ein bei der Herstellung in den Hals d eingeführtes Ventil e schliefst den Behälter. Um aber auch ein Eintreten von Schmutztheilchen in die zweite Ausbauchung m zu vermeiden, wird der soweit fertige und gefüllte Aufbewahrungsbehälter mittels einer Kappe_/ luftdicht geschlossen. Besteht der Behälter, wie angenommen, aus Glas, so schmilzt man die Kappe unmittelbar an und "trennt sie im Gebrauchsfalle ab, wobei ein Diamantschnitt bei g das Abtrennen erleichtert. Soll eine' Injection gemacht werden, so führt man die Nadelspitze η der hohlen Nadel h i in die Blutgefäfse unter die Haut ein. Hierauf schiebt man die Oeffnung des Flüssigkeitsgefäfses über das Nadelende /. Dasselbe stöfst gegen den Ventilkegel e und das flüssige Medikament wird unter dem Druck des sich ausdehnenden Gases durch die Nadelhöhlung k in deren Inneres und schliefslich beim Ausfliefsen aus der Spitze in den menschlichen Körper übergeführt. The liquid container α , made of glass or other suitable material, is partially filled with the medicament b , but sterile air or any suitable gas is introduced into the free space under a certain pressure. A valve e introduced into the neck d during manufacture closes the container. However, in order to prevent dirt particles from entering the second bulge m , the storage container, which has been completed and filled, is closed airtight by means of a cap. If the container is made of glass, as assumed, the cap is immediately melted and, if necessary, it is cut off, a diamond cut at g making it easier to cut off. If an injection is to be made, the needle tip η of the hollow needle is guided hi into the blood vessels under the skin. The opening of the liquid vessel is then pushed over the end of the needle /. The same pushes against the valve cone e and the liquid medicament is under the pressure of the expanding gas through the needle cavity k into its interior and finally as it flows out transferred from the tip into the human body.
Sowie man das Gefäfs anhebt, schliefst sich das Ventil e sofort, es kann somit auch keine Flüssigkeit mehr entweichen und auch umgekehrt keine Luft hinzutreten. Der Durchmesser des Nadelendes Z entspricht möglichst der Gefäfsöffnung und der lichten Weite der ersten Einschnürung, damit einmal eine sichere Führung erzielt wird und weiterhin die Flüssigkeit nicht etwa zwischen Nadelschaft und Wandung herausfliefst. Ein etwaiger Tropfen wird inAs soon as the vessel is lifted, the valve e closes immediately, so that no more liquid can escape and, conversely, no air can enter. The diameter of the needle end Z corresponds as much as possible to the vessel opening and the clear width of the first constriction, so that a secure guidance is achieved and the liquid does not flow out between the needle shaft and the wall. Any drop will be in
