Description

Die Erfindung betrifft das Einführen von Kathetern, insbesondere Blasenkatheter.The Invention relates to insertion of catheters, in particular bladder catheters.

Es handelt sich um eine trichterartige Einführhilfe in Form eines an der Spitze offenen Kegelmantels aus sterilisierbarem, elastischem Material (Kunststoff) mit einem breiten Spalt von der Basis bis zur Kegelspitze mit entlang des Spalts nach innen gerundeten Kanten und von der Basis zur Kegelspitze abnehmender Federkraft des Materials, erreicht durch eine abnehmende Wandstärke. Der Spalt ist etwas breiter als der Durchmesser des zu verwendenden Katheters. (1)It is a funnel - like insertion aid in the form of a conical mantle of sterilizable elastic material (plastic) with a wide gap from the base to the apex with edges rounded inwards along the gap and from the base to the apex of decreasing spring force of the cone Materials, achieved by a decreasing wall thickness. The gap is slightly wider than the diameter of the catheter to be used. ( 1 )

Es sind spezielle Einführhilfen für die nasale Intubation ( DE 84 36 309 U1 ), für Intestinalendoskopie ( DE 100 24 660 A1 ) und als Katheterbesteck für Blutgefäße ( DE 31 17 802 A1 ) bekannt.These are special introducers for nasal intubation ( DE 84 36 309 U1 ), for intestinal endoscopy ( DE 100 24 660 A1 ) and as a catheter set for blood vessels ( DE 31 17 802 A1 ) known.

Die übliche Methode einen Blasenkatheter einzuführen ist, den Bereich um die Harnröhrenöffnung zu desinfizieren, dann die Spitze des Katheters möglichst geschickt in Harnröhrenöffnung einzufädeln und ihn soweit nachzuschieben, bis die Spitze in der Harnblase ist.The usual method to insert a bladder catheter is the area around the urethral opening too disinfect, then thread the tip of the catheter as skillfully as possible in the urethral opening and push it far enough until the tip is in the urinary bladder.

Das Hauptproblem hierbei ist, dass die Katheterspitze trotz Desinfektion am äußeren Teil der Harnröhrenöffnung Infektionskeime aufnehmen, dann direkt in die Harnblase transportieren und dort gefährliche Harnwegsinfektionen auslösen kann.The Main problem here is that the catheter tip despite disinfection on the outer part the urethral opening infection germs then transport directly into the bladder and there dangerous Cause urinary tract infections can.

Die Einführhilfe dient dazu, den Vorgang des katheterns zu vereinfachen und das Infektionsrisiko zu vermindern.The insertion serves to simplify the procedure of the catheter and to increase the risk of infection Reduce.

Die Einführhilfe kann mit zwei Fingern zusammengedrückt (3) und dann mit der Spitze in den vorderen Teil der Harnröhre eingeführt werden. Wird sie dort gehalten und wieder entspannt wird sie den vorderen Teil der Harnröhre etwas aufdehnen. Anschließend kann man den Katheter leicht durch das trichterartige Innere einführen, ohne dass seine Spitze den äußeren Bereich um die Harnröhrenöffnung berührt. Durch den Spalt kann die Einführhilfe entfernt werden, sobald der Katheter weit genug eingeführt ist. Die nach innen gerundeten Kanten des Spalts (2) vermeiden, dass es zu versehentlichen Quetschungen im Bereich der Harnröhrenöffnung kommt. Die zur Kegelspitze hin abnehmende Federkraft gewährleistet hierbei, dass sich der Spalt über die gesamte Länge ausreichend zusammendrücken lässt (3).The insertion aid can be compressed with two fingers ( 3 ) and then inserted with the tip into the anterior part of the urethra. If she is kept there and relaxed again, she will slightly dilate the anterior part of the urethra. Subsequently, the catheter can be easily inserted through the funnel-like interior without its tip touching the outer area around the urethral opening. Through the gap, the introducer can be removed as soon as the catheter is inserted far enough. The inwardly rounded edges of the gap ( 2 ) avoid accidental bruising around the urethral opening. The spring force decreasing towards the cone tip ensures that the gap can be squeezed over the entire length ( 3 ).
