Beschreibung: Schließventil für eine Infusions-Tropfenkammer eines medizinischen Infusionsbestecks Description: Closing valve for an infusion drip chamber of a medical infusion set
Stand der Technik: Infusionslösungen für Patienten (Elektrolyt, Glukose, Antibiotika etc.) werden mittels eines Infusionsbestecks, daß eine Tropfenkammer enthält, verabreicht. State of the art: Infusion solutions for patients (electrolytes, glucose, antibiotics, etc.) are administered using an infusion set that contains a drop chamber.
Alle handelsüblichen Tropfenkammern entleeren sich am Ende einer Infusion und es wird sich entsprechend des Zentralen Venendrucks des Patienten ein Flüssigkeitsspiegel einstellen, der zwischen der Tropfenkammer und dem patientenseitigen Anschluß liegt. Die darüber enthaltene Luftsäule , käme sie in den Körper, gefährdet den Patienten, wenn das Infusionsbesteck nicht vor einer erneuten Infusion entlüftet wird. Hierzu kommen bisher umständliche Vorgehensweisen zur Anwendung, als da wären: Hochziehen der Schlauchklemme; Tieferhängen der Infusionslösung unterhalb des Herzniveaus; Retrogrades Durchspülen des Systems.All commercially available drip chambers empty at the end of an infusion and a fluid level will be established between the drip chamber and the patient-side connection, depending on the patient's central venous pressure. The column of air contained above, if it were to enter the body, would endanger the patient if the infusion set was not vented before another infusion. To date, complicated procedures have been used for this, such as: pulling up the hose clamp; hanging the infusion solution lower below the level of the heart; retrograde flushing of the system.
Problem: Es gilt zu verhindern, daß sich eine Luftsäule am Ende einer Infusion in einem Infusionsbesteck ausbildet. Problem: It is important to prevent a column of air from forming in an infusion set at the end of an infusion.
Erfindung: Am Ende der Tropfenkammer eines Infusionsbestecks
ist ein 90° kegelförmiger Auslaß integriert. In der Tropfenkammer schwimmt eine mindestens 6 mm große Polypropylen
Kugel. Der verwendete Kunststoff ist physiologisch unbedenklich, seine Wasseraufnahme hat den Wert Null.
Am Ende einer Infusion wird die Kunststoffkugel den Auslaß der Tropfenkammer verschließen und verhindert damit den
Verlust des Flüssigkeitsspiegel aus der Tropfenkammer. Invention: A 90° conical outlet is integrated into the end of the drip chamber of an infusion set. A polypropylene ball measuring at least 6 mm floats in the drip chamber. The plastic used is physiologically harmless and its water absorption is zero.
At the end of an infusion, the plastic ball will close the outlet of the drop chamber and thus prevent the loss of liquid level from the drop chamber.

erreichter Vorteil: Mit der Erfindung wird erreicht, daß
zum Ende einer Infusion ein sofortiges Verschließen des Systems entfällt, um ein Eindringen von Luft zu verhindern.
Eine sonst nachfolgende Luftsäule hätte bei Eintritt in den Körper lebensgefährliche Folgen. Die Verabreichung
einer weiteren Infusion bewirkt die sofortige Freigabe des kegelförmigen Auslasses im Moment des steigenden Flüssigkeitsspiegels
Achieved advantage: The invention achieves that
At the end of an infusion, there is no need to immediately close the system to prevent air from entering. An air column that would otherwise follow would have life-threatening consequences if it entered the body. The administration of another infusion causes the cone-shaped outlet to be immediately released at the moment the liquid level rises
Figurenbeschreibung: Character description :
Ein Ausführungsbeispiel der Erfindung wird anhand der
Figur 1 erläutert:An embodiment of the invention is described with reference to
Figure 1 explains:
diese zeigt ein komplettes medizinisches Infusionsbesteck mit der Tropfenkammer 1, einer Polypropylen Kunststoffkugel 2 und dem 90° kegelförmigen Auslaß 3. Mit der Schlauchklemme 4 kann das System verschlossen und die Infusion gestoppt werden.This shows a complete medical infusion set with the drop chamber 1, a polypropylene plastic ball 2 and the 90° conical outlet 3. The system can be closed and the infusion stopped using the hose clamp 4.
Nach dem Füllen des Systems mit der zu applizierenden Infusionslösung
wird die Kugel 2 auf der Flüssigkeitsoberfläche in der Tropfenkammer 1 schwimmen. Ist die Infusions
lösung durchgelaufen fällt die Kugel 2 in den Auslaß 3. Ein Betätigen der Schlauchklemme 4 zum Ende der Infusion
entfällt damit.After filling the system with the infusion solution to be administered, the ball 2 will float on the liquid surface in the drop chamber 1. Once the infusion solution has run through, the ball 2 falls into the outlet 3. Pressing the hose clamp 4 at the end of the infusion
is therefore no longer applicable.
