Abstract

Venenfinder, gekennzeichnet durch ein biegsames Trägerband (10), das auf seiner unteren Fläche eine Mehrzahl von in einer Reihe nebeneinander angeordneten, auf einen Blutpuls ansprechenden Sensoren (12) und auf seiner anderen Seite eine entsprechende Mehrzahl von jeweils einem der Sensoren (12) zugeordneten Leuchten (14) trägt, wobei bei Ansprechen eines Sensors (12) die zugehörige Leuchte (14) zum Ansprechen gebracht wird.Vein finder, characterized by a flexible carrier tape (10) which on its lower surface has a plurality of sensors (12) which are arranged in a row next to one another and which respond to a blood pulse and on its other side a corresponding plurality of each associated with one of the sensors (12) Lights (14) carries, whereby when a sensor (12) responds, the associated light (14) is made to respond.

Description

Die Erfindung betrifft einen Venenfinder.The invention relates to a venous finder.

Bei dem Applizieren eines Medikamentes über eine Kanüle in eine Vene ist es erforderlich, die Vene zuvor zu finden. Die JP H02 174 854 A , die US 2005/0215875 A1 und die DE 2652268 A1 beschreiben Venenfinder. Diese aber erlauben nicht das einfache, praxisgerechte Finden der Vene.When applying a drug through a cannula into a vein, it is necessary to find the vein beforehand. The JP H02 174 854 A , the US 2005/0215875 A1 and the DE 2652268 A1 describe vein finder. But these do not allow the simple, practice-oriented finding of the vein.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Gerät zu schaffen, das dazu in der Lage ist, den Verlauf der Vene, in die ein Medikament über eine Kanüle einzubringen ist, auf einfache Weise zu finden.The invention is therefore based on the object to provide a device that is able to easily find the course of the vein, in which a drug is to be introduced via a cannula.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Die Unteransprüche geben bevorzugte Ausgestaltungen an.According to the invention, this object is solved by the features of claim 1. The dependent claims indicate preferred embodiments.

Die Erfindung wird im Folgenden anhand einer Zeichnung erläutert, in der ein Ausführungsbeispiel der Erfindung in einer Schnittdarstellung wiedergegeben ist.The invention is explained below with reference to a drawing, in which an embodiment of the invention is shown in a sectional view.

Der Venenfinder besteht aus einem biegsamen Trägerband. Aus seiner unteren Fläche trägt das Trägerband eine Mehrzahl von in einer Reihe nebeneinander angeordneten, auf einen Blutpuls ansprechende Sensoren, die etwa ein mm breit sind. Aus seiner oberen Fläche ist eine entsprechende Mehrzahl von jeweils einem der Sensoren 12 zugeordnete Leuchten vorgesehen. Eine Auswertelektronik, die an dem Trägerband befestigt ist, wertet die Signale der Sensoren aus und erkennt das Ansprechen eines der Sensoren und bringt die bzw. den Sensoren die jeweils ansprechen, zugehörige LED 14 zum Leuchten: bei Aufleuchten lediglich einer LED liegt die Vene unmittelbar unter der aufleuchtenden Leuchtdiode, leuchten zwei LED auf, liegt die Vene zwischen den entsprechenden Leuchtdioden (bzw. den zugehörigen Sensoren).The vein finder consists of a flexible carrier tape. From its lower surface, the carrier tape carries a plurality of juxtaposed in a row, responsive to a blood pulse sensors, which are about one mm wide. From its upper surface is a corresponding plurality of each one of the sensors 12 assigned lights provided. An electronic evaluation unit, which is attached to the carrier tape, evaluates the signals from the sensors and detects the response of one of the sensors and brings the sensor or the respective address, associated LED 14 to light up: when only one LED lights up, the vein lies directly under the flashing LED, two LEDs light up, the vein lies between the corresponding light-emitting diodes (or the corresponding sensors).

Die Sensoren 12 können auf die von einem Blutpuls bewirkte Temperaturänderung, den von einem Blutpuls verursachten Drucksanstieg, die von einem Blutpuls verursachte Farbänderung des Gewebes oder aber den vom Blutpuls verursachten Schall erkennen.The sensors 12 may detect the change in temperature caused by a blood pulse, the increase in pressure caused by a blood pulse, the color change of the tissue caused by a blood pulse, or the sound caused by the blood pulse.

Bei einer bevorzugten Ausführungsform sind zwei Trägerbänder mit LED und zugehörigen Sensoren vorgesehen, wobei die beiden Trägerbänder mit einem Abstand voneinander angeordnet sind, die ein Durchführen einer Kanüle erlauben.In a preferred embodiment, two carrier bands with LED and associated sensors are provided, wherein the two carrier bands are arranged at a distance from each other, which allow a passage of a cannula.

Das Trägerband kann nach Art eines Armbandes bzw. (bei Anlegen am Oberarm) eines Armreifs ausgebildet sein.The carrier tape may be formed in the manner of a bracelet or (when applied to the upper arm) of a bangle.

Der erfindungsgemäß ausgebildete Venenfinder erlaubt ein schnelles und zuverlässiges Finden der Vene, in die eine Kanüle einzustechen ist. Ein Verfehlen der Vene ist unwahrscheinlich, ein Einspritzen in das die Vene umgebende Gewebe statt in die Vene selbst wird weitgehend ausgeschlossen.The inventively designed vein finder allows a fast and reliable finding of the vein into which a cannula is to stab. Missing the vein is unlikely, injecting into the tissue surrounding the vein rather than into the vein itself is largely ruled out.
