Die Blutdruckmessung bei laufender Infusion am selben Arm eines Patienten stellt ein bislang ungelöstes Problem und ständiges Ärgernis im Alltag von Anästhesie- und Intensivpflegeabteilungen dar.The measurement of blood pressure while the infusion is in progress on the same arm of a patient represents a hitherto unsolved problem and constant nuisance in everyday life of Anesthesia and intensive care departments.
Infusionen werden meist durch Venen der Hand, des Unterarmes oder der Ellenbeuge verabreicht.Infusions are usually given through veins of the hand, forearm, or the crook of the elbow administered.
Die übliche Blutdruckmessung erfordert eine kurzfristige Stauung des Armes durch Aufblasen einer um den Oberarm gelegten Manschette.The usual blood pressure measurement requires a short-term congestion of the arm by inflating a cuff placed around the upper arm.
Dabei wird das Blut in den Venen des Armes zurückgestaut, Blut i.^ießt in den Infusionsschlauch, und die zurückgedrängte Infusionsflüssigkeit Züllt die gesamte Tropfkammer des Infusionsgerätes. Die Wiederherstellung einer ordnungsgemäß tropfenden und sauberen Infusion dauert dann mehrere Minuten, wobei oft die Umgebung mit Blut verschmutzt und die Sterilität der Infusion gefährdet werden.The blood is dammed back in the veins of the arm, blood flows into the arm Infusion tube, and the displaced infusion liquid fills the entire drip chamber of the infusion device. Restoring a properly Dripping and clean infusion then takes several minutes, often contaminating the area with blood and making the infusion sterile be endangered.
Die Gebrauchsanleitungen der meisten Blutdruckmeßgeräte verbieten daher die Blutdruckmessung an dem Arm, an dem auch die Infusion liegt. Tatsächlich aber steht bei den meisten Patienten wegen der Erfordernisse der Oparstionslagerung, der sterilen Abdeckung oder auch der Art der Verletzung nur ein Arm für Infusion und Blutdruckmessung zur Verfügung, oder an beiden Armen müssen Infusionen laufen.The instructions for use of most blood pressure monitors therefore prohibit the Blood pressure measurement on the arm on which the infusion is also placed. In fact, in most patients, because of the requirements of the oparstion position, the sterile cover or the type of injury only one arm is available for infusion and blood pressure measurement, or both arms must be available Infusions are running.
Dann muß vor jeder Blutdruckmessung die Infusion abgeklemmt und anschließend wieder geöffnet werden, was besonders bei automatischer Blutdruckmessung oft vergessen wird. Dieser Nachteil behindert auch die Verbreitung der ansonsten sehr nützlichen automatischen Blutdruckmeßgeräte.Then the infusion must be disconnected and then before each blood pressure measurement be opened again, which is often forgotten, especially with automatic blood pressure measurement. This disadvantage also hinders the spread of the otherwise very useful automatic blood pressure monitors.
Zweck der Erfindung ist die Beseitigung dieses Nachteils durch automatische Abklemmung der Infusion während jeder Blutdruckmessung. The purpose of the invention is to eliminate this disadvantage by automatically clamping off the infusion during each blood pressure measurement.
Hierfür bietet sich eine einfache und zuverlässige Lösung dadurch an, daß
alle herkömmlichen Blutdruckmeßgeräte zu Beginn der Messung mittels einer Luftpumpe einen Druck aufbauen, der am Ende der Messung wieder abgelassen
wird. Daraus ergibt sich die Möglichkeit, die Klemme am Infusionsschlauch durch Druckluft aus dem Blutdruckmeßgerät schließen und durch Federkraft
wieder öffnen zu lassen, so daß die Infusionsklemme durch jedes herkömmliche Blutdruckmeßgerät zugleich angetrieben und gesteuert werden kann.
In der einfachsten konstruktiven Ausführung braucht das Gerät nur aus einem
verformbaren Hohlkörper (4) und einem festen Widerlager (3) zu bestehen, zwischen denen der Infusionsschlauch (1) hindurchgeführt und bei Aufblasen
des Hoiilkörpers abgeklemmt wird. Es kann klein und leicht genug sein, um an
beliebiger Stelle an den frei hängenden Inft'i-ionsschlauch geklemmt zu werden.
Als Anschluß wird nur ein Schlauch (5) zu einem in den Druckluftschlauch des
Blutdruckmeßgerätes eingesetzten T-Stück benötigt.A simple and reliable solution is offered for this in that all conventional blood pressure measuring devices use an air pump to build up a pressure at the beginning of the measurement, which pressure is released again at the end of the measurement. This results in the possibility of closing the clamp on the infusion tube with compressed air from the blood pressure meter and opening it again by spring force, so that the infusion clamp can be driven and controlled by any conventional blood pressure meter at the same time.
In the simplest structural design , the device only needs to consist of a deformable hollow body (4) and a fixed abutment (3), between which the infusion tube (1) is passed and is clamped off when the hollow body is inflated. It can be small and light enough to be clamped anywhere on the free-hanging infusion tube.
The only connection required is a hose (5) to a T-piece inserted into the compressed air hose of the blood pressure measuring device.
Um der Neigung vieler Medizingerätehersteller zu technisch aufwendigen Lösungen zu entsprechen, kann aber auch eine elektrisch betätigte Infusionsklemme mit besonderer Steuerung duch die Elektronik -ines automatischen Blutdruckmeßgerätes verwendet werden.To the inclination of many medical device manufacturers to technically complex solutions However, an electrically operated infusion clamp with special control by the electronics of an automatic blood pressure measuring device can also be used be used.
