Description
Hohlnadel. Zu diagnostischen Zwecken, meistens zur Anstellunc ider Wassermannschen Reaktion, sowie -zu therapeutischen Zwecken (Aderlaß) entnimmt man mittels einer Hohlnadef Blitit aus -einer Vene (Venenpunkition) und fängt ,es !in einem Glasröhrchen auf. Zu diesem Eingriff benutzt man heutzutage meistenteils die ».Straußsche Kanüle«, das ist eine Hohilnadelmit einem geeigneten Griff. Viele Ärzte machen di-e Venenpunktion mit einer Rekordspitze. Dabei muß -das Blut nachher erst aus der Spritze in das Glasröhrchen hineingespritzt -werden. Bei der ersten Art der Venenpunktion besteht eine ;Schwierigkeit dar-in, das Blut gleich in idem Röhröhen aufziufängen, ohne daß etwas daneben läuft. Zu diesem Zweck setzt man im allgemeinen die Nadel gleich so auf das, Röhrchen, daß der Griff der Nadel auf dem oberen Rand des Röhr#h-en,s liegt. Bei dieser Lagerung hat sich der Nachteil -herausgestellt, daß man dii Nadel, die jetzt a-nit,dem Röhrchen eine Einheit bilden soll, nicht fest in, ider #Gewalt hat, da der Zeigefinger !Deng Nadelgriff auf das Röhrchen, drückt und das Röhrchen mit Daumen und Mittelfinger gehalten wird. Da der Eingriff aus anatornischen Gründen ein sehr präziser sein muß, muß man den Zeigefingger,zum Festhalten, des Röhrchens zur Verfügung haben, wenn man Deng notwenidigen Stich sicher und bequem ausführen will.Hollow needle. For diagnostic purposes, mostly for setting up the Wassermann reaction, and for therapeutic purposes (bloodletting), blitit is removed from a vein (venous puncture) using a hollow needle and it is collected in a small glass tube. Nowadays the "Strauss cannula," a hollow needle with a suitable handle, is mostly used for this operation. Many doctors do di-e venipuncture with a record high. The blood must first be injected from the syringe into the glass tube afterwards. With the first type of venipuncture there is a difficulty in collecting the blood at the same height as the tube without anything running off. For this purpose, the needle is generally placed on the tube in such a way that the handle of the needle lies on the upper edge of the tube. In this storage, the disadvantage has -herausgestellt that one should form dii needle, the a-nit now, the tube one unit, not f est in, has ider #Gewalt, since the index finger! Deng needle handle to the tube presses and the tube is held with the thumb and middle finger. Since the procedure has to be very precise for anatomical reasons, one must have the index finger available to hold the tube if one wants to carry out the necessary stitch safely and comfortably.
Durch id-en Gegenstand der Erfindung soll dieser Mangel beseitigt werden. Das Wesen der Erfindung besteht darin, daß idie Nadel so ausgestaltet wird, daß sie auf jedes Glasröhrchen aufsetzbar 4st und mit ihm während der Blutentnahme eine feste Einheit bildet. Man Icann!daidurch -das Röhrchen mit Daumen und Zeigefinger festhalten, was die einzige rationelle Haltung ist.This deficiency is to be eliminated by the same subject matter of the invention. The essence of the invention is that the needle is designed in such a way that it can be placed on each glass tube and forms a solid unit with it during the blood withdrawal. You can do this by holding the tube with your thumb and forefinger, which is the only rational posture.
Auf der Zeichnung sinü drei AusfÜhrungsbei.spiele der Erfindung in Ansicht und Draufsicht dargestellt. Die unten mit einer durchbohrten Er.weiterung b versehen-- Hohlnadel, a.,ist mit -einem Griff d ausgerüstet, der mit einer Vorrichtung zum Auf setzen auf idas Glasröhrchen c versehen ist. Gemäß Abb. i und 2 besteht die Befestigungsvorrichtung aus einem -die Glaswand timgreifenden, U-förmig gestaltetenBügel g, gegen den von außen eine Befestigungsschraübe f wirkt. Durch Anziehen der letzteren wird die Nadel mit dem ,Glas Verlbullden.On the drawing sinü three AusfÜhrungsbei.spiele of the invention shown in view and plan view. The hollow needle, a., Is provided with a pierced extension b at the bottom and is equipped with a handle d, which is provided with a device for placing on the glass tube c. According to Figs. I and 2, the fastening device consists of a U-shaped bracket g that engages the glass wall and against which a fastening screw f acts from the outside. When the latter is tightened, the needle is bolted to the glass.
Gemäß Abb. 3 und 4 ist der Griff d mit einer,das Glas c umfassenden Klammer h versehen, ideren Öffnungsweite durch eine Stellschraube f geregelt wird.According to Fig. 3 and 4, the handle d is provided with a clamp h encompassing the glass c, the opening width of which is regulated by an adjusting screw f.
Man, kann die Einriehtung auch so treffen, daß der #Griff d als kreisrunde Platte ist, was den Vorteil hat, daß idas Glas c vollkommen während -der Blutentnahme abgedeckt i-st.The arrangement can also be made in such a way that the handle d is a circular plate, which has the advantage that the glass c is completely covered while the blood is being drawn.
Die Platte d trägt unten z. B. drei Zapf-en i, durch, welche Schrauben f gegen die Glas.wand gepreßt werden und so -die Nadel festhalten.The plate d carries below z. B. three pegs i, by which screws f are pressed against the Glas.wand and so hold the needle.
