Abstract
Description
Die Erfindung bezieht sich auf eine Infusions- und Blutdruckmeßanordnung gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to an infusion and blood pressure measuring arrangement according to the generic term of claim 1.
Bei der Intensivmedizin werden Patienten normalerweise über eine Infusionsanordnung mit Medikamenten, Nährflüssigkeit oder Kochsalzlösung versorgt, wobei die Infusionsanordnung über eine Infusionsnadel mit einem Blutgefäß des Patienten verbunden ist. Als Blutgefäße kommen dabei Venen und/oder Arterien in Frage.at In intensive care, patients are usually treated via one Infusion arrangement supplied with medication, nutrient fluid or saline, wherein the infusion arrangement via an infusion needle is connected to a blood vessel of the patient. As blood vessels come while veins and / or arteries in question.
Zusätzlich wird bei solchen Patienten fortlaufend der Blutdruck überwacht, indem in die Infusionslinie ein Druckmeßsensor zwischengeschaltet ist, der direkt den Druck des angeschlossenen Gefäßes mißt. Häufig soll dabei sowohl der arterielle als auch der venöse Blutdruck gemessen werden.In addition will In such patients, the blood pressure is monitored continuously by adding to the infusion line a pressure measuring sensor which is directly connected to the pressure of the connected Vessel measures. Often should Both arterial and venous blood pressures are measured.
Hierfür ist es bekannt, über Umschaltventile ein und denselben Druckmeßsensor wahlweise mit einem arteriellen Zugang oder einem venösen Zugang zu verbinden.This is it known, about Changeover valves one and the same pressure sensor optionally with a arterial access or venous access.
Für eine einwandfreie
Blutdruckmessung muß sichergestellt
sein, daß das
gesamte Infusions- und Blutdruckmeßsystem keine Luft- oder Gasblasen enthält, weshalb
in der Praxis ein zusätzliches
Entlüftungsventil
vorgesehen ist. Im Stand der Technik, der in
In der Praxis kommt es immer wieder vor, daß Klinikpersonal diesen Entlüftungsanschluß auch dazu benutzt, Blutproben zu entnehmen, da übliche zur Blutentnahme verwendete medizinische Spritzen problemlos an den Luer-Anschluß passen. An dem Entlüftungsanschluß entnommene Blutproben sind jedoch für eine Blutanalyse meist ungeeignet, da nicht sichergestellt ist, daß an dieser Stelle wirklich nur reines Blut abgezogen wird und nicht auch eine Mischung aus Blut und Infusionsflüssigkeit.In In practice, it happens again and again that clinical staff this vent connection also used to take blood samples, as usual used for blood collection medical syringes fit easily to the Luer connector. Removed at the vent port However, blood samples are for a blood analysis mostly unsuitable because it is not ensured that on this place really only pure blood is withdrawn and not also a mixture of blood and infusion fluid.
Die Verwendung von zwei Ventilen bringt auch noch ein weiteres Problem, das insbesondere in der Pädiatrie von Bedeutung ist. Durch die zwei Ventile und Verbindungsleitungen zwischen den Ventilen wird das Gesamtvolumen des Infusions- und Blutdruckmeßsystems vergrößert mit der Folge, daß bei einer Blutentnahme relativ viel Blut aus dem Körper des Patienten in das System überführt werden muß, was bei Kleinkindern oder Säuglingen zu kritischen Zuständen führen kann.The Using two valves also brings up another problem especially in paediatrics is important. Through the two valves and connecting lines between the valves, the total volume of the infusion and blood pressure measuring system enlarged with the consequence that at a Bleeding relatively much blood from the patient's body will be transferred to the system must, what in toddlers or infants to critical conditions to lead can.

Aufgabe der Erfindung ist es daher, die Infusions- und Blutdruckmeßanordnung des Standes der Technik dahingehend zu verbessern, daß ihr Gesamtvolumen verkleinert ist. Zusätzlich soll eine Blutentnahme an dem Entlüftungsanschluß verhindert werden.The object of the invention is therefore to improve the infusion and Blutdruckmeßanordnung the prior art in that their total volume is reduced. In addition, a should Blood collection at the vent port can be prevented.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is achieved by the features specified in claim 1 solved. Advantageous embodiments and further developments of the invention are the dependent claims refer to.
Das Grundprinzip der Erfindung liegt darin, für die Umschaltung zwischen venösem und arteriellem Zugang und Verbindung des Systems mit Atmosphäre nur noch ein einziges Ventil zu verwenden. Hierdurch wird das Gesamtvolumen des Systems wesentlich verringert. Nach einer Weiterbildung der Erfindung ist vorgesehen, daß der mit Atmosphäre verbundene Anschluß des Ventils direkt mit einem Entlüftungsschlauch verbunden ist, der durch eine Schlauchklemme absperrbar ist. An diesen Entlüftungsschlauch kann eine üblicherweise zur Blutentnahme verwendete Spritze nicht mehr angeschlossen werden. Damit ist die unzulässige Blutentnahme an dem Entlüftungsanschluß verhindert. Eine weitere Volumenverringerung erhält man dadurch, daß auch an den Anschluß des Ventils, der mit dem arteriellen Zugang verbunden wird, ein Schlauch fest angeschlossen ist, so daß die Luer-Verbindung an dieser Stelle entfällt. Bei Langzeitpatienten wird nämlich der arterielle Anschluß nur relativ selten ausgewechselt und kann mehrere Tage verwendet werden, während der venöse Anschluß häufiger, beispielsweise täglich gewechselt werden muß.The The basic principle of the invention is to switch between venous and arterial access and connection of the system with atmosphere only to use a single valve. This will make the total volume of the system significantly reduced. According to a development of the invention is provided that the associated with the atmosphere Connection of the Valve directly with a vent hose is connected, which can be shut off by a hose clamp. At this breather hose can one usually no longer be connected to the blood collection syringe. This is the invalid Blood collection at the vent connection prevented. A further reduction in volume is obtained by the fact that also on the connection of the Valve connected to the arterial access, a hose is firmly connected, so that the Luer connection is omitted at this point. For long-term patients that is the arterial connection only relatively rarely replaced and can be used for several days during the venous Connection more frequently, for example, changed daily must become.
