Abstract
Arm (1) für einen Antriebskopf einer Spritzenpumpe, umfassend zumindest ein erstes Element (2) aus einem ersten Material und ein zweites Element (3) aus einem zweiten Material, wobei das erste Material verschieden ist von dem zweiten Material.Arm (1) for a drive head of a syringe pump, comprising at least a first element (2) of a first material and a second element (3) of a second material, wherein the first material is different from the second material.
Description
Die Erfindung betrifft einen Arm für einen Antriebskopf einer Spritzenpumpe und einen Antriebskopf.The invention relates to an arm for a drive head of a syringe pump and a drive head.
Spritzenpumpen sind allgemein bekannt. Sie werden insbesondere im medizinischen Bereich eingesetzt um beispielsweise Infusionslösungen über einen längeren Zeitraum mit definierten Flussraten einem Patienten zuzuführen. Sie weisen eine Aufnahme für eine Spritze auf, von der eine Spritze aufgenommen werden kann, und weisen einen üblicherweise translatorisch verstellbaren Antriebskopf auf, mit dem ein Spritzenkolben der aufgenommenen Spritze in einen Spritzenzylinder der Spritze hineingedrückt werden kann um auf diese Weise sich in der Spritzentrommel befindliche Flüssigkeit zu fördern.Syringe pumps are well known. They are used in particular in the medical field to supply, for example, infusion solutions over a long period of time with defined flow rates to a patient. They have a receptacle for a syringe, from which a syringe can be received, and have a usually translatorally adjustable drive head with which a syringe plunger of the recorded syringe can be pressed into a syringe barrel of the syringe in order in this way located in the syringe barrel To promote fluid.
Um den Spritzenkolben an dem Antriebskopf zu halten, umfasst der Antriebskopf in der Regel einen Arm oder zwei Arme. Auf diese Weise wird verhindert, dass beispielsweise durch Unterdruck der Spritzenkolben in die Spritzentrommel hineingezogen wird, ohne dass dies durch eine Bewegung des Antriebkopfes veranlasst wird („Siphoneffekt”). Solche Spritzenpumpen mit einem Antriebskopf, der zumindest einen solchen Arm oder zwei solcher Arme aufweist, offenbaren beispielsweise die Offenlegungsschriften
Aufgabe der vorliegenden Erfindung ist es, einen verbesserten Arm für einen Antriebskopf einer Spritzenpumpe und einen Antriebskopf für eine Spritzenpumpe mit mindestens einem Arm zu schaffen.The object of the present invention is to provide an improved arm for a drive head of a syringe pump and a drive head for a syringe pump with at least one arm.
Die Aufgabe wird gelöst durch einen Arm und einen Antriebskopf gemäß den unabhängigen Ansprüchen.The object is achieved by an arm and a drive head according to the independent claims.
Der erfindungsgemäße Arm für einen Antriebskopf einer Spritzenpumpe umfasst zumindest ein erstes Element aus einem ersten Material und ein zweites Element aus einem zweiten Material, wobei das erste Material verschieden ist von dem zweiten Material.The arm for a drive head of a syringe pump according to the invention comprises at least a first element of a first material and a second element of a second material, wherein the first material is different from the second material.
Durch die Verwendung von unterschiedlichen Materialien können verschiedene vorteilhafte Effekte erzielt werden. Einerseits ist es möglich, den Arm beispielsweise kostengünstig herzustellen, aber gleichzeitig eine ausreichende mechanische Belastbarkeit des Armes zu gewährleisten. Des Weiteren ist es durch die Verwendung unterschiedlicher Materialien zusätzlich oder alternativ zu den genannten Vorteilen möglich, den Arm ästhetisch ansprechend herzustellen. Alternativ oder zusätzlich kann durch eine geeignete Materialwahl zu dem ein geringes Gewicht des Armes erreicht werden. Schließlich erlaubt die Wahl von unterschiedlichen Materialien auch, zumindest an gewissen Abschnitten des Armes elektrischen Entladungen vorzubeugen.By using different materials, various beneficial effects can be achieved. On the one hand it is possible, for example, to produce the arm inexpensively, but at the same time to ensure sufficient mechanical strength of the arm. Furthermore, it is possible by the use of different materials in addition to or alternatively to the advantages mentioned to produce the arm aesthetically pleasing. Alternatively or additionally, by a suitable choice of material to the low weight of the arm can be achieved. Finally, the choice of different materials also allows at least certain portions of the arm to prevent electrical discharges.
Der erfindungsgemäße Antriebskopf für eine Spritzenpumpe umfasst mindestens einen erfindungsgemäßen Arm, vorzugsweise zwei Arme.The drive head according to the invention for a syringe pump comprises at least one arm according to the invention, preferably two arms.
Die Erfindung soll im Folgenden anhand einer Figur näher erläutert werden.The invention will be explained in more detail below with reference to a figure.
Die Figur zeigt eine Ausführungsform eines erfindungsgemäßen Armes in einer perspektivischen Ansicht.The figure shows an embodiment of an arm according to the invention in a perspective view.
