Description

Amnioskopiesonde zum Feststellen einer Trübung oder Verfärbung des Fruchtwassers Die Erfindung betrifft eine Amnioskopiesonde zum Feststellen einer Trübung oder Verfärbung des Fruchtwassers in der Fruchtblase einer Schwangeren. Amnioscopy probe to detect cloudiness or discoloration of the Amniotic fluid The invention relates to an amnioscopy probe for detecting a Cloudiness or discoloration of the amniotic fluid in the amniotic sac of a pregnant woman.

Die Beobachtung der Farbe des Fruchtwassers in der Fruchtbiase der Schwangeren während der letzten Wochen einer Schwangerschaft hat sich in der Medizin als ein wichtiges diagnostisches Hilfsmittel zur Erkennung von Frühschäden des Feten erwiesen.Observing the color of the amniotic fluid in the amniotic sac Pregnant women during the last few weeks of pregnancy has turned to medicine as an important diagnostic tool for the detection of early damage to the fetus proven.

Die Methode ist unter dem Namen Amnioskopie bekannt.The method is known as amnioscopy.

Bisher bediente man sich dabei röhrenförmiger, vorzugsweise konischer Tuben, welche die Scheidenwand spreizen und bis an den Muttermund herangeführt werden. Durch Kombination eines solchen Tubus mit einer Lichtquelle kann die im Muttermund durchscheinende Fruchtblase gesehen und die Farbe des Fruchtwassers visuell beurteilt werden. Da es für die Diagnose stellung auf feine Farbunterschiede von schwach hellgrUn bis dunkelgrün bzw. schwarz ankommt und die Beobachtungen in den verschiedenen Kliniken mit unterschiedlichen Lichtquellen durchgeführt werden, ist eine absolute Aussage über den Verfärbungsgrad und ein Vergleichen der Befunde prak-tisch unmöglich.So far, tubular, preferably conical ones have been used Tubes that spread the vaginal wall and are brought up to the cervix. By combining such a tube with a light source, it can be placed in the cervix See translucent amniotic sac and visually assess the color of the amniotic fluid will. As for the diagnosis, there are subtle color differences from slightly light green until dark green or black arrives and the observations in the various clinics carried out with different light sources is an absolute statement about the degree of discoloration and a comparison of the findings practically impossible.

Der Erfindung liegt die Aufgabe zugrunde eine Amnioakopiesonde zu schaffen, die den Diagnostiker in die Lage versetzt, eine objektive Feststellung über den Trübungs- oder Verfärbungsgrad des Fruchtwassers zu treffen.The invention is based on the object of an amniocopic probe create that enables the diagnostician to make an objective determination about the degree of cloudiness or discoloration of the amniotic fluid.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das in die Körperhöhle einzuführende Sondenende eine Kappe mit einer eine durchsichtige Wandung- besitzende zentrale Vertiefung aufweist, die mit einem bis zum anderen Sondenende führenden Saugrohr verbunden ist, und daß seitlich längs des Saugrohrs zwei Lichtleiter angeordnet sind, deren Enden sich an der durchsichtigen Wandung der zentralen Vertiefung gegenüberliegen. Dabei sind die Lichtleiterenden in der Sonde jeweils mit einem 900 Prisma versehen. Um das Sterilisieren der Sonde bzw. der Kappe zu erleichtern, ist die Kappe abnehmbar.This object is achieved in that the in the End of the probe to be introduced into the body cavity a cap with a transparent wall owning central recess, which with one to the other end of the probe leading suction tube is connected, and that laterally along the suction tube two light guides are arranged, the ends of which are on the transparent wall of the central recess opposite. The fiber optic ends in the probe are each marked with a 900 prism provided. To make it easier to sterilize the probe or cap, the cap is removable.

Ein Ausführungsbeispiel der Amnioskopiesonde ist in der Zeichnung dargestellt und wird im folgenden in Verbindung mit dem erfindungsgemäßen Verfahren beschrieben. Es zeigen Fig. 1 eine teilweise geschnittene Gesamtansicht der Amnioskopiesonde Fig. 2 eine teilweise geschnittene vergrößerte Teildarstellung des in die Körperhöhle einzuführenden Endes der Sonde gemäß Fig. 1 Die Sonde wird mit Hilfe eines bekannten Amnioskoptubus an die Fruchtblase herangeführt, bis die Kappe 2 daran anliegt. Durch Saugwirkung über das Saugrohr 3 erfolgt ein Einsaugen einer kleinen Partie der Fruchtblasenwand in die zentrale Vertiefung 4 der Kappe 21 Dabei gelangt etwas Fruchtwasser in den Bereich der Vertiefung 4. Mittels zweier Lichtleiter 5, 6, die längs des Saugrohrs 3 geführt sind und deren Enden sich an der durchsichtigen Wandung der Vertiefung 4 gegenüberliegen, wird über 90° Prismen 7, 8, Licht, das über den einen Lichtleifer eingestrahlt wird, durch den Bereich der Vertiefung 4 hindurchgeschickt und über den anderen Lichtleiter einer nicht dargestellten Meßeinrichtung zugeführt, und einer photometrischen Messung unterzogen.An embodiment of the amnioscopy probe is shown in the drawing and is shown below in connection with the method according to the invention described. 1 shows a partially sectioned overall view of the amnioscopy probe Fig. 2 is a partially sectioned enlarged partial representation of the in the body cavity to be introduced end of the probe according to FIG. 1 The probe is with the help of a known Amnioscope tube brought up to the amniotic sac until the cap 2 rests against it. By A small portion of the amniotic sac wall is sucked in via the suction tube 3 In the central recess 4 of the cap 21 some amniotic fluid gets into the Area of the recess 4. By means of two light guides 5, 6, which run along the suction tube 3 are performed and the ends of which are on the transparent wall of the recess 4 are opposite, through 90 ° prisms 7, 8, light that passes through one of the light guides is irradiated, sent through the area of the recess 4 and fed via the other light guide to a measuring device (not shown), and subjected to a photometric measurement.

Das mit der Fruchtblasenwand in die Vertiefung 4 eingesaugte Fruchtwasser führt je nach Trübung oder Verfärbung zu einer Verminderung der Lichttransmission, die an einem Meßinstrument direkt abgelesen werden kann. Durch Zwischenschaltung verschiedenfarbiger Filter ist eine Objektivierung der Fruchtwasserverfärbung möglich.The amniotic fluid sucked into the recess 4 with the amniotic sac wall leads to a reduction in light transmission depending on the cloudiness or discoloration, which can be read directly on a measuring instrument. Through interposition Different colored filters can be used to objectify the discoloration of the amniotic fluid.
