Description

Klebbare Meßsonde mit einem Meßwertaufnehmer Adhesive measuring probe with a transducer

Die Erfindung betrifft eine Meßsonde mit einem Meßwertaufnehmer, welcher eine Aussparung aufweist, die, mit Klebstoff gefüllt, zur Befestigung der Meßsonde an der Hautoberfläche dient.The invention relates to a measuring probe with a transducer, which has a recess which, filled with adhesive, is used to attach the measuring probe serves on the surface of the skin.

Eine derartige Meßsonde ist aus der DE-OS 26 19 471 bekannt geworden.Such a measuring probe is known from DE-OS 26 19 471.

Hierbei handelt es sich um einen Fühler zur Messung der Oberflächentemperatur, welcher aus einem scheibenförmigen Körper besteht, in dem umlaufende Aussparungen angeordnet sind. Bevor die Meßsonde auf die Hautoberfläche angebracht wird, werden die. Aussparungen mit einem Klebstoff gefüllt und danach auf der Hautoberfläche befestigt. Die Elektroden der Meßsonde befinden sich dann in Kontakt mit der Hautoberfläche, ohne daß weitere Befestigungselemente notwendig sind.This is a sensor for measuring the surface temperature, which consists of a disk-shaped body in which circumferential recesses are arranged. Before the measuring probe is attached to the skin surface, be the. Recesses filled with an adhesive and then on the surface of the skin attached. The electrodes of the measuring probe are then in contact with the skin surface, without the need for additional fasteners.

Von besonderer Bedeutung sind Meßsonden zur Messung von Temperaturen, Blutgaspartialdrücken durch die Haut, oder auch die Messung von bioelektrischen Signalen. In zunehmendem Maße werden solche Signale auch von Feten und Kindern während der Geburt gemessen, um den Geburtsvorgang ständig überwachen zu können.Measuring probes for measuring temperatures, Blood gas partial pressures through the skin, or the measurement of bioelectrical ones Signals. Increasingly, such signals are also used by fetuses and children during measured at birth in order to be able to constantly monitor the birth process.

Hierbei erweist sich als nachteilig, daß vor der Anbringung des Meßwertaufnehmers auf der Hautoberfläche des Kindes der Kleber in die dafür vorgesehenen Aussparungen angebracht werden muß.This proves to be disadvantageous that before the transducer is attached on the child's skin surface, place the adhesive in the recesses provided must be attached.

Eine derart präparierte Elektrode kann nur von erfahrenen Fachleuten sicher und haltbar an die Kopfschwarte des noch ungeborenen Kindes angebracht werden. Die Schwierigkeit besteht u.a. darin, daß der Kleber beim Einführen in den Geburtskanal durch die Umgebungsbedingungen schon vor dem Klebevorgang irreversiblenveränderungen unterworfen sein kann.An electrode prepared in this way can only be carried out by experienced specialists can be attached securely and durably to the scalp of the still unborn child. The difficulty is, among other things, that the adhesive does not get into the birth canal when it is inserted irreversible changes due to the environmental conditions before the gluing process may be subject to.

Aber auch in allen anderen Fällen, in denen eine Meßsonde an irgendeiner Stelle der Hautoberfläche befestigt werden soll, ist es wünschenswert, die Meßsonde zunächst an den für die spezielle Messung angepaßten Meßort aufzubringen und ihn erst nach Überprüfung einer einwandfreien Signalabgabe endgültig zu befestigen.But also in all other cases in which a measuring probe is attached to any Point to be attached to the skin surface, it is desirable to use the measuring probe first to apply to the measurement location adapted for the special measurement and him to be finally attached only after checking that the signal has been emitted correctly.

Die Aufgabe der vorliegenden Erfindung wird darin gesehen, eine Meßsonde dergenanrt# Art derart zu verbessern, daß die Klebstoffzuführung nach dem Aufsetzen der Meßsonde auf die Hautoberfläche ausgeführt werden kann.The object of the present invention is seen in a measuring probe dergenanrt # Kind to improve in such a way that the glue feed after placement the measuring probe can be carried out on the skin surface.

Die Aufgabe wird dadurch gelöst, daß eine Klebstoffzuführungsleitung in die Aussparung mündet.The object is achieved in that an adhesive feed line opens into the recess.

Der durch die Erfindung erzielte Vorteil liegt im wesentlichen darin, daß über die Klebstoffzuführungsleitung mit geeigneten Mitteln, wie z.B. einer Klebstoffspritze, nach erfolgtem Aufsetzen der Meßsonde auf die Hautoberfläche der Klebstoff in die dafür vorgesehene Aussparung gebracht werden kann, ohne die Meßsonde selbst nochmals von ihrem Platz entfernen zu müssen. Auch größere Abstände zwischen Befestigungsort der Meßsonde und Zuführungsstelle des Klebstoffs können mit der Klebstoffzuführungsleitung überbrückt werden, so daß eine für die Befestigung der Meßsonde geeignete Arbeitsposition ermöglicht wird.The advantage achieved by the invention lies essentially in that via the adhesive supply line with suitable means, such as an adhesive syringe, after the measuring probe has been placed on the skin surface, the adhesive in the provided recess can be brought without the measuring probe itself again having to remove them from their place. Also larger distances between the fastening point the measuring probe and the glue feed point can be connected to the glue feed line be bridged, so that a suitable working position for attaching the measuring probe is made possible.

In besonders einfacher und vorteilhafter Weise kann die Aussparung aus einem zumindest teilweise konkav gewölbten Meßwertauf nehmer gebildet sein. Die Zuführungsleitung für den Klebstoff mündet in dieser Aussparung beispielsweise zentral am höchsten Punkt der Wölbung, in welcher zusätzlich vorteilhafterweise eine Entlüftungsbohrunq anqeordnet ist. Durch diese kann die durch den Klebstoff verdrängte Luft in die Umgebung entweichen.In a particularly simple and advantageous manner, the recess be formed from an at least partially concave measuring transducer. The feed line for the adhesive opens into this recess, for example centrally at the highest point of the bulge, in which additionally advantageous a vent hole is arranged. Through this, the through the adhesive displaced air escape into the environment.

Eine weitere vorteilhafte Ausgestaltung der Aussparung ist darin zu sehen, daß entlang dem Umfang des Meßwertaufnehmers eine Mulde vorgesehen ist, in welche an irgendeiner Stelle die Klebstoffzuführungsleitung mündet, und an einer weiteren frei wählbaren Stelle eine entsprechende Entlüftungsbohrung vorgesehen ist.Another advantageous embodiment of the recess is to be included therein see that a trough is provided along the circumference of the transducer, in which opens at some point the adhesive supply line, and at one a further freely selectable point a corresponding vent hole is provided is.

Ein Ausführungsbeispiel der Meßsonde wird anhand der schematischen Zeichnung näher erläutert und im folgenden beschrieben.An embodiment of the measuring probe is based on the schematic Drawing explained in more detail and described below.

In der einzigen Figur ist der Meßwertaufnehmer als ein Elektrodenträger 3 im Schnitt gezeichnet, welcher in der Mitte eine zur Hautoberfläche hin konkav gewölbte Aussparung 2 aufweist. In diese Aussparung 2 mündet eine Klebstoffzuführungsleitung 1. Zu dieser Mündung beabstandet ist eine Entlüfungsbohrung 8 in dem Elektrodenträger 3 vorgesehen, welche die Aussparung 2 mit der Umgebung verbindet. Auf der der Hautoberfläche zugewandten Seite des Elektrodenträgers 3 befinden sich weiterhin Meßelektroden 5, von denen die entsprechenden Meßsignale durch Meßleitungen 7, welche durch die Leitungskanäle 6 geführt sind, an die nicht dargestellten Meß- und Auswerteeinheiten abgegeben werden. Des weiteren sind am Rande des Elektrodenträgers 3 umlaufende Mulden 4 angebracht, in welche ebenfalls ein zur Befestigung der Meßsonde geeigneter Klebstoff angebracht wird. Die Mulden 4 können entweder über einen nicht dargestellten Verbindungskanal mit der Aussparung 2 durch dieselbe Klebstoffzuführungsleitung 1 mit Klebstoff gefüllt werden, oder sie besitzt eine nicht dargestellte eigene Klebstoffzuführungsleitung.In the single figure, the transducer is shown as an electrode carrier 3 drawn in section, which in the middle is a concave towards the skin surface Has curved recess 2. An adhesive feed line opens into this recess 2 1. At a distance from this mouth is a vent hole 8 in the electrode carrier 3 is provided, which connects the recess 2 with the environment. On the surface of the skin facing side of the electrode carrier 3 are still measuring electrodes 5, of which the corresponding measuring signals through measuring lines 7, which through the Line channels 6 are guided to the measuring and evaluation units, not shown be delivered. Furthermore, on the edge of the electrode carrier 3 are circumferential Wells 4 attached, in which also a suitable for attaching the measuring probe Adhesive is attached. The troughs 4 can either have a not shown Connection channel with the recess 2 through the same adhesive feed line 1 to be filled with adhesive, or it has its own, not shown Adhesive feed line.

Dabei kann die Aussparung 2 entfallen oder, wenn eine besonders starke Haftung gewünscht ist, kann die Aussparung 2 noch zusätzlich zu den Mulden 4 vorgesehen sein.The recess 2 can be omitted or, if a particularly strong one If adhesion is desired, the recess 2 can also be provided in addition to the troughs 4 be.
