Description
Katheter, insbesondere Intratraeheal-Ka,theterCatheters, especially intratraeheal catheters
ein Durch ein älteres Patent des Anmelders isV, insbesondere als Intratracheal-Katheter geeigneter Katheter geschützt, dessen Wandung durch eine in Gummi oder .Kunststoff eingebettete schraubenförmige Draht- oder Kunststoff-i'eder gebildet wird, welche an einem Ende eine Spitze nach Art einer Flötenspitze, am anderen Ende ein schlauchförmiges Anschlußstücl·; aufweist, wobei sämtliche Teile durch einen gemeinsamen glatten "überzug aus ^autselmk oder elastischem Kunststoff miteinander verbunden sind.by an earlier patent of the applicant isV, in particular as Intratracheal catheter suitable catheter protected, the wall by a screw-shaped embedded in rubber or plastic Wire or plastic i'eder is formed which at a whistle-like point at one end, and at the other End of a tubular connection piece; has, with all Parts by a common smooth "coating of ^ autselmk or elastic plastic are connected to each other.
Die Erfindung betrifft eine weitere Ausgestaltung eines solchen Katheters in der Art, daß anstelle einer flötenartigen Spitze auch am vorderen Ende, ebenso wie am hinteren Ende des Katheterrohres nur ein starkwandiges jächlauehstück mit zentralerThe invention relates to a further embodiment of such a catheter in the manner that instead of a flute-like one Tip also at the front end, just like at the rear end of the catheter tube, only a thick-walled jächlauehstück with a central
Öffnung angesetzt ist. Dieser Katheter eignet sich infolge seiner zentralen Öffnung u.a. zur unmittelbaren Verwendung bei LuftröhrenVerengung, er kann aber auch als Verlängerungsund Anschlußstück für die Verbindung eines Intratracheal-Katheters nach dem älteren Patent mit einem Sarkosegerät oder dergl., beispielsweise zur Einführung bis in die unteren Bronchien dienen, wozu er mit Hilfe einer einfachen üuffe, beispielsweise aus vernickeltem oder verchromtem Messing oder aus V2a-Stahl oder dergl. mit dem hinteren Anschlußstück des ersteren verbunden wird.Opening is set. Due to its central opening, this catheter is suitable, among other things, for immediate use with narrowing of the trachea, but it can also be used as an extension Connection piece for the connection of an intratracheal catheter according to the earlier patent with a sarcosis device or the like, for example to introduce into the lower bronchi, for which it can be done with the help of a simple For example, made of nickel-plated or chrome-plated brass or of V2a steel or the like. With the rear connector of the the former is connected.
Eine weitere zweckmäßige Ausbildung dieses Katheters kann darin bestehen, daß er aus elektrisch leitfähigem Kautschuk oder Latex hergestellt wird, so daß die elektrische äpannung, die durch die Staubteilchen in dem durchströmenden Gfas hervorgerufen wird, dadurch sowohl von dem narkosegerät als auch von dem Patienten durch Erdung abgeleitet wird.Another useful design of this catheter can consist in that it is made of electrically conductive rubber or latex is made so that the electrical voltage that caused by the dust particles in the gas flowing through is thereby diverted from both the anesthesia machine and the patient by grounding.
Zwei Ausführungsbeispiele von Kathetern nach dem Muster sind in der Zeichnung in sch emetischer 51OMi dargestellt.Two embodiments of catheters according to the pattern are shown in the drawing in schematic 5 1 OMi.
Fig. 1 zeigt einen zur selbständigen Verwendung bestimmten Katheter dieser Art,Fig. 1 shows a catheter of this type intended for independent use,
I'ig. 2 die Verwendung eines solchen !Catheters als Anschlußstück für einen Intratraeheal-Katheter nach dem älteren Patent.I'ig. 2 the use of such a catheter as a connector for an intratraeheal catheter according to the earlier patent.
Mit 1 ist das Katheterrohr bezeichnet, das durch eine in Gummi oder Kunststoff eingebettete Schraubenfeder 7 mit gleichartigen Windungsabständen gebildet wird. An beiden Enden des Katheterrohres ist ein verhältnismäßig starkwandiges G-ummirohr 3 angesetzt, das mit dem Katheterrohr durch einen glatten Überzug aus Kautschuk oder Kunststoff zu einer Einheit verbunden ist. In dieser Form kann der Katheter als selbständiges Instrument verwendet werden.1 with the catheter tube is referred to, which by a coil spring embedded in rubber or plastic 7 with the same Winding distances is formed. At both ends of the catheter tube is a relatively thick-walled G-ummi pipe 3 attached, which is connected to the catheter tube by a smooth cover made of rubber or plastic to form a unit is. In this form the catheter can be used as a stand-alone instrument.
Fig. 2 zeigt die Verwendung dieses Instrumentes zum Zwecke der Verlängerung eines Intratraeheal-Ks,theters 4 mit llötenspitze 2, zu welchem Zweck das hintere Ende 3a des Katheters 4 durch eine Metallmuffe 5 mit dem einen Lnde 3 des Katheters nach j?ig. 1 verbunden ist»Fig. 2 shows the use of this instrument for the purpose of extending an Intratraeheal-Ks, theter 4 with soldering tip 2, for what purpose the rear end 3a of the catheter 4 through a metal sleeve 5 with one end 3 of the catheter after j? y. 1 is connected »
