Description

Blutentnahmeglas. Bei der Blutentnahme aus der Armvene mittels Hohlnadel bietet die gleichzeitige Handhabung von Nadel und Auffangglas oft Schwierigkeiten, und es läßt sich kaum vermeiden, daß die ersten Blutstropfen anstatt in das Glas über die Finger des Arztes und den Arm des Patienten laufen. Um diesen Übelstand zu beheben, der auf der räumlichen Trennung von Glas und Nadel beruht, hat man Nadeln konstruiert, an denen das Aufnahmeglas, mittels einer Klammer o. dgl. befestigt, gleichsam aufgehängt werden kann, so daß#,es in seiner Stellung der Nadel gegenüber stets fixiert ist. Aber auch diese Konstruktion bietet eine Reihe von Nachteilen: Sie ist unhandlich und unbequem in der Anwendung, da der Schwerpunkt nach unten verlegt ist und außerhalb der Angriffsfläche liegt, sie ist auch nicht aseptisch, da die Verbindungsteile schwer zugänglich und schlecht zu reinigen sind.Blood collection tube. When taking blood from the arm vein using a hollow needle the simultaneous handling of the needle and collecting glass often presents difficulties, and it can hardly be avoided that the first drops of blood instead of falling into the glass run over the doctor's fingers and patient's arm. About this evil to fix, which is based on the spatial separation of glass and needle, you have needles constructed, to which the receiving glass, fastened by means of a clamp or the like, can be hung up, so to speak, so that #, it in its position opposite the needle is always fixed. But this construction also has a number of disadvantages: It is unwieldy and inconvenient to use because the center of gravity is down is misplaced and lies outside the attack surface, it is also not aseptic, since the connecting parts are difficult to access and difficult to clean.

Demgegenüber geht die Erfindung von dem Gedanken aus, nicht das Glas an die Nadel zu hängen, als vielmehr umgekehrt die Nadel auf das Glas aufzustecken und so eine aus Glas und Nadel bestehende einheitliche Konstruktion zu schaffen. Wie die Abbildung zeigt, setzt sich die neue Konstruktion aus drei Einzelteilen zusammen, nämlich dem Blutentnahmeglas a, einer auf dieses aufsetzbaren Kappe b und der auf die Kappe aufsteckbaren Nadel d.In contrast, the invention is based on the idea, not the glass hanging on the needle, rather than sticking the needle on the glass the other way around and so a unitary construction made of glass and needle to create. As the illustration shows, the new construction consists of three individual parts together, namely the blood collection tube a, a cap b that can be placed on it and the needle that can be attached to the cap d.

Das Glas ist ein gewöhnliches kräftiges Probeglas mit glattem Rande. Auf dasselbe ist erfindungsgemäß eine Kappe b aufgeschliffen oder mit geschlitztem Unterteil aufgesetzt, um so in bekannter Weise den unvermeidlichen Differenzen im Umfange der Probegläschen zu begegnen. Sie läuft in einen Hohlkonus c aus, auf den die mit entsprechendem Konus d' versehene Nadel d aufgesteckt wird.The glass is an ordinary, strong test glass with a smooth rim. According to the invention, a cap b is ground on the same or fitted with a slotted lower part in order to counter the inevitable differences in the circumference of the sample vials in a known manner. It ends in a hollow cone c, onto which the needle d provided with a corresponding cone d 'is pushed.

Damit des Blut bei dem Gebrauche ungehindert in das Glas einfließt, ist die Aufsatzkappe mit einem Luftloch b' für den Austritt der Luft versehen. Abb. i zeigt die Erfindung in teilweisem Längsschnitt, Abb. 2 in der Ansicht.So that the blood flows unhindered into the glass during use, the top cap is provided with an air hole b 'for the air to escape. Fig. i shows the invention in partial longitudinal section, Fig. 2 in the view.

Zum Gebrauch wird das Glas mit der aufgesteckten Nadel fest und bequem in die Hand genommen und in die Ader eingeführt, worauf das Blut durch den in der Ader vorhandenen Blutdruck durch die Kappillare d hindurch in das Glas a hineingetrieben wird, ohne daß auch nur ein Tropfen danebenfließt. Der ganze Apparat liegt glatt und sicher in der Hand, ist vollkommen aseptisch und in einem Augenblick zusammengesetzt und? auseinandergenommen.With the attached needle, the glass becomes firm and comfortable for use taken in hand and introduced into the vein, whereupon the blood flows through the in the The existing blood pressure is driven through the capillary d into the glass a without even a drop flowing by it. The whole apparatus lies flat and safe in hand, is completely aseptic and assembled in an instant and? taken apart.
