Description
Die Erfindung bezieht sich auf eine medizinische Druckmeßanordnung gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to a medical pressure measuring device according to the preamble of Claim 1.

Diese Art von Druckmeßwandlern ist heute weit verbreitet. Sie werden üblicherweise mit genormten Luer-Verbindern und genormten Schläuchen an die Patienten angeschlossen. Dabei hat sich auch für die Druckmeßkammer ein Standard herausgebildet, nämlich daß diese die Form eines Hohlzylinders mit einem Durchmesser von 1,6 bis 1,8 mm hat.These Type of pressure transducers is widely used today. They are usually standardized Luer connectors and standardized tubing connected to the patient. It also has for the pressure measuring chamber a standard emerged, namely that these the shape of a hollow cylinder with a diameter of 1.6 to 1.8 mm has.
In der Pädiatrie stellt sich jedoch das Problem, daß aufgrund der geringen Blutmenge von Neugeborenen und Kleinkindern spezielle Schläuche, Apparate und Blutdruckmeßwandler verwendet werden müssen, die ein geringeres Volumen haben, um zum Befüllen des Systems dem Patienten möglichst wenig Blut zu entnehmen. Daher sind die Standard-Druckmeßwandler in der Pädiatrie nicht einzusetzen. Es werden daher spezielle Druckmeßwandler für die Pädiatrie hergestellt, die ein geringeres Volumen haben. Dies bedingt einen entsprechend hohen Fertigungsaufwand, höhere Produktionskosten sowie auch Zusatzkosten für Lagerhaltung, Vertrieb etc.In pediatrics However, the problem arises that due to the small amount of blood newborns and infants special tubes, apparatus and blood pressure transducers must be used which have a lower volume in order to fill the system to the patient preferably to draw little blood. Therefore, the standard pressure transducers in pediatrics not to use. There are therefore special pressure transducers for the pediatrics manufactured, which have a smaller volume. This requires one correspondingly high production costs, higher production costs as well also additional costs for Warehousing, sales etc.
Es wäre daher wünschenswert, die für erwachsene Patienten eingesetzten Druckmeßwandler auch in der Pädiatrie einsetzen zu können.It would be therefore desirable, the for adult patients also used pressure transducers in pediatrics to be able to use.
Aufgabe der Erfindung ist es daher, herkömmliche Druckmeßwandler für Erwachsene mit möglichst geringem Aufwand so auszubilden, daß sie in der Pädiatrie einsetzbar sind, insbesondere ein geringeres Volumen der Druckmeßkammer haben.task The invention is therefore conventional pressure transducer for adults with as possible to train little effort so that they are in pediatrics can be used, in particular a smaller volume of the pressure measuring chamber to have.
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 in einem Adapter, dessen Außendurchmesser dem Innendurchmesser der Druckmeßkammer herkömmlicher Druckmeßwandler entspricht und dessen Innendurchmesser kleiner ist als der Innendurchmesser der Druckmeßkammer herkömmlicher Druckmeßwandler, wobei der Adapter an seinem Außenumfang eine Öffnung aufweist, die einem druckempfindlichen Sensorelement gegenüberliegt.The Basic principle of the invention lies in an adapter whose outer diameter the inner diameter of the pressure measuring chamber conventional pressure transducer corresponds and whose inner diameter is smaller than the inner diameter of pressure-measuring chamber conventional pressure transducers, the adapter having an opening on its outer periphery, which is opposite to a pressure-sensitive sensor element.
Der Innendurchmesser des Adapters ist vorzugsweise gleich oder kleiner als 1,0 mm. Die Öffnung des Adapters entspricht der Projektionsfläche des Sensorelementes.Of the Inner diameter of the adapter is preferably equal to or smaller as 1.0 mm. The opening of the adapter corresponds to the projection surface of the sensor element.
Die Länge des Adapters entspricht der Länge der Druckmeßkammer. Der Adapter ist vorzugsweise ein Kunststoffteil, das vorzugsweise in Spritzgußtechnik hergestellt wird.The Length of the Adapter corresponds to the length the pressure measuring chamber. The adapter is preferably a plastic part, preferably in injection molding will be produced.
Zur Herstellung eines für die Pädiatrie geeigneten Druckmeßwandlers kann daher ein für Erwachsene geeigneter Druckmeßwandler verwendet werden, in dessen Druckmeßkammer lediglich der genannte Adapter eingesetzt wird. Dies ist mit einem einfachen Montageschritt durchzuführen. Alle übrigen Teile des herkömmlichen Druckmeßwandlers für Erwachsene können daher weiter verwendet werden. Vorzugsweise ist die Druckmeßkammer aus durchsichtigem Material und der Adapter aus eingefärbtem, jedoch ebenfalls durchsichtigem Material, so daß der Anwender sofort erkennen kann, daß es sich um einen Druckmeßwandler für die Pädiatrie handelt, wobei aufgrund der durchsichtigen Materialien der Druckmeßkammer und des Adapters gleichwohl durch Sichtkontrolle geprüft werden kann, ob die Druckmeßkammer mit Flüssigkeit gefüllt ist und keine Gasblasen enthält.to Producing a for pediatrics suitable pressure transducer can therefore be a for Adult suitable pressure transducer be used, in the pressure measuring only the said Adapter is used. This is a simple assembly step perform. The rest Parts of the conventional pressure transducer for adults can therefore continue to be used. Preferably, the pressure measuring chamber made of transparent material and the adapter made of colored, however also transparent material, so that the user recognize immediately that can do it a pressure transducer for the pediatrics is due to the transparent materials of the pressure measuring chamber and the adapter are nevertheless tested by visual inspection can, whether the pressure measuring chamber with liquid filled is and contains no gas bubbles.
Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles im Zusammenhang mit der Zeichnung ausführlicher erläutert. Es zeigt:in the The following is the invention with reference to an embodiment in connection with the drawing in more detail explained. It shows:
