BeschreibungDescription
Extern tragbare Pumpenspritze zur intravenösen Medikamentengabe.Externally portable pump syringe for intravenous medication administration.
z.B. Patienten mit Beinvenenthrombosen werden in der Regel stationär behandelt und erhalten über eine Dauer von 10 Tagen das Medikament Heparin.For example, patients with deep vein thrombosis are usually treated as inpatients and receive the drug heparin for a period of 10 days.
Die kontinuierliche Infusion erfolgt über eine intravenöse Kanüle, die über einen dünnen Schlauch mit einer Spritze verbunden ist, in die das Medikament eingefüllt wird. Die gefüllte Spritze wiederum ist in einen sog. " Perfusor " eingespannt, d.h. in ein mit Netzspannung betriebenes Gerät, das je nach Einstellung das Medikament mit einer bestimmten Dosierung aus der Spritze in das Schlauchsystem und über die Kanüle in das Venensystem und damit in den Blutkreislauf des Patienten treibt.The continuous infusion takes place via an intravenous cannula, which is connected to a syringe via a thin tube, into which the medication is filled. The filled syringe, in turn, is clamped into a so-called "perfusor", i.e. a device operated with mains voltage, which, depending on the setting, pushes the medication at a certain dosage from the syringe into the tube system and via the cannula into the venous system and thus into the patient's bloodstream.
Das Netzgerät (Perfusor) bindet den Patienten an das Bett, beim Verlassen des Bettes (Toilettengang etc.) wird die Medikamenteninfusion unterbrochen, was eben für die gewünschte kontinuierliche Dauerinfusion von Nachteil ist.The power supply unit (perfusor) ties the patient to the bed; when the patient leaves the bed (going to the toilet, etc.) the medication infusion is interrupted, which is a disadvantage for the desired continuous infusion.
Batteriebetriebene externe (netzstromunabhängige) Perfusoren werden alternativ eingesetzt. Diese müssen in einer Tasche mitgetragen werden, sind relativ teuer und sind problematisch hinsichtlich der Sterilität und der Mehrfachverwendung bei verschiedenen Patienten.Battery-operated external (mains-independent) infusion pumps are used as an alternative. These must be carried in a bag, are relatively expensive and are problematic in terms of sterility and multiple use on different patients.
Eine weitere Alternative stellt eine am Arm tragbare Spritze dar, bei der vom Krankenhauspersonal erstens das Medikament in die Spritze gefüllt und zweitens ein eingebauter Ballon mit Luft aufgeblasen werden muß. Dieser treibt dann über einen Stempel das Medikament aus der Kammer in den Schlauch, der über eine Kanüle mit dem Patienten verbunden ist. Die Spritze hält z.B. 5 Tage.Another alternative is a syringe that can be worn on the arm. Hospital staff must first fill the syringe with medication and then inflate a built-in balloon with air. This then uses a plunger to push the medication out of the chamber into the tube that is connected to the patient via a cannula. The syringe lasts for 5 days, for example.

Diese Spritze wird mit einer Binde am Arm des Patienten angewickelt. Sie enthält 100.000 Einheiten Heparin und infundiert pro 24 Stunden eine gewünschte Menge von z.B. 20.000 Einheiten Heparin in die Vene des Patienten.This syringe is wrapped around the patient's arm with a bandage. It contains 100,000 units of heparin and infuses a desired amount of, for example, 20,000 units of heparin into the patient's vein every 24 hours.
Der Vorteil dieses Systems liegt in der Mobilität des Patienten. Die Therapie kann ambulant durchgeführt werden und durch die " Einmalverwendung " der Spritze wird das Infektionsrisiko vermieden.The advantage of this system is the mobility of the patient. The therapy can be carried out on an outpatient basis and the "single use" of the syringe avoids the risk of infection.
Ein Problem ist, daß der Patient meist seine Kleidungsstücke nicht mehr anziehen kann, da er mit der auftragenden Spritze am Arm nicht mehr durch den Ärmel seines Hemdes, Sakkos oder Mantels schlüpfen kann. Dadurch ist er deutlich beeinträchtigt.One problem is that the patient is often unable to put on his clothes because he can no longer slip the syringe through the sleeve of his shirt, jacket or coat. This has a significant impact on him.
Dieses Problem wird durch den im Schutzanspruch 1 aufgeführten halbmondförmigen Querschnitt der Spritze gelöst.This problem is solved by the crescent-shaped cross-section of the syringe as set out in claim 1 .
Mit der Erfindung des halbmondförmigen Querschnittes wird erreicht, daß die Spritze handlicher wird. Sie liegt flacher am Arm an und die Kleidungsstücke können besser übergezogen werden.The invention of the crescent-shaped cross-section means that the syringe is easier to handle. It sits flatter on the arm and clothes can be pulled over it more easily.
Eineu/orteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 gegeben.An advantageous embodiment of the invention is given in claim 2 .
Durch die Erfindung integrierter Armbänder an der Spritze entfällt das Anwickeln mit einer Binde. Die Spritze kann problemlos zum Waschen des Armes kurzfristig abgenommen werden. Dadurch ist der Patient im Alltag trotz seiner laufenden Therapie weniger eingeschränkt. Thanks to the invention of integrated wristbands on the syringe, it is no longer necessary to wrap a bandage around it. The syringe can easily be removed for a short time to wash the arm. This means that the patient is less restricted in their everyday life despite their ongoing therapy.

Eine weitere Ausgestaltung der Erfindung ist im Schutzanspruch 3 gegeben.A further embodiment of the invention is given in claim 3 .
Eine Spritze, bei der gebrauchsfertig eine Kammer mit Treibgas und eine Kammer mit dem Medikament gefüllt ist, ermöglicht die schnellere und sichere Handhabung des Systems bei der Therapie.A syringe with one chamber filled with propellant gas and one chamber filled with the medication, ready for use, enables faster and safer handling of the system during therapy.
Die Spritze muß nicht zuerst aufgefüllt werden und damit wird das Risiko einer unsachgemäßen Füllung u. evtl. falschen Dosierung reduziert.The syringe does not need to be filled first, which reduces the risk of improper filling and possibly incorrect dosing.
Weiterhin entfällt das Aufblasen des Ballons.Furthermore, there is no need to inflate the balloon.
Die in den Schutzansprüchen angeführten Erfindungen sollen eine Für den Patienten gut tragbare und eine für das Personal leicht anzulegende Pumpenspritze schaffen.The inventions set out in the claims are intended to create a pump syringe that is easy for the patient to carry and easy for the staff to use.
