Description

"Amnioskopiesonde zum Feststellen einer Trübung oder Verfärbung des Bruchtwasserst Die Erfindung betrifft eine Amnioskopsonde zum Feststellen einer Trübung oder Verfärbung des Fruchtwassers in der Fruchtbiase einer Schwangeren, bei der das in die Körperhöhle einzuführende Sondenende eine Kappe mit einer eine durchsichtige Wandung besitzenden zentralen Vertiefung aufweist, die mit einem bis zum anderen Sondenende führenden Saugrohr verbunden ist, längs dessen zwei Lichtleiter angeordnet sind, deren Enden sich an der durchsichtigen Wandung der zentralen Vertiefung gegenüberliegen nach Patent ......."Amnioscopy probe to detect cloudiness or discoloration of the Bruchtwasserst The invention relates to an amnioscope probe for detecting a Cloudiness or discoloration of the amniotic fluid in the amniotic sac of a pregnant woman, in which the probe end to be inserted into the body cavity has a cap with a has transparent wall owning central recess with a to is connected to the other end of the probe leading suction tube, along its two light guides are arranged, the ends of which are on the transparent wall of the central recess opposite according to patent .......

(OS 2 034 870).(OS 2 034 870).

Mit einer derartigen Amnioskopiesonde ist der Diagnostiker in der Lage, eine objektive Feststellung über den rübungs-oder Verfärbungsgrad des Fruchtwassers zu treffen; indem er Licht photometrisch untersucht, das durch einen Teil des mit einer kleinen Partie derruchtblasenwand in die Sonde eingesaugten Fruchtwassers hindurchgeleitet worden ist.With such an amnioscopy probe, the diagnostician is in the Able to make an objective statement about the degree of cloudiness or discoloration of the amniotic fluid hold true; by photometrically examining light passing through part of the mit a small portion of the amniotic sac wall of the amniotic fluid sucked into the tube has been passed through.

Bei der bekannten Sonde wird das Licht einer außerhalb angeordneten iiichtquelie zunächst durch einen Lichtleiter an das untere Sondenende geführt und dort durchstrahlt es das in die Sondenvertiefung eingesaugte Pruchtwæsser. Das durch Trübung oder Verfärbung des Fruchtwassers mehr oder weniger geschwächte Licht gelangt dann über den weiteren Lichtleiter aus der Sonde heraus zu einem photoelektrischen Meßgerät.In the known probe, the light is arranged outside iiichtquelie first guided through a light guide to the lower end of the probe and irradiated there it is the Pruchtwæsser sucked into the well. That by cloudiness or Discoloration of the amniotic fluid more or less weakened light then gets over the other light guide out of the probe to a photoelectric measuring device.

Der relativ lange Weg des Lichtes, gegeben durch die Zu-und Rückführung iw Lichtleiterhzum bzw. vom Sondenende bedingt erhebliche Lichtverluste. Außerdem können durch die lichtleiter spektrale Abweichungen eintreten, die die erforderliche Eichung des fotoelektrischen Meßeräts erschweren.The relatively long path of light, given by the entry and return iw light guides to or from the end of the probe cause considerable light losses. aside from that Spectral deviations can occur due to the fiber optics, which make the required Make calibration of the photoelectric measuring device difficult.

Der Erfindung liegt deshalb die Aufgabe zugrunde, die beknnte Sonde so zu verbessern, daß Lichtverluste und Störeinfiüsse.The invention is therefore based on the object of the known probe to be improved in such a way that light losses and interference infuences.

soweit wie möglich ausgeschaltet werden.be switched off as far as possible.

Diese Aufgabe wird erfindllngsgemäß dadurch gelöst, daß statt eines der beiden Lichtleiter ein Jichtempfindliches elektrisches Element, z. B. eine Fotozelle vorgesehen ist, die an der durchsichtigen Wandung der Kappe gegenüber dem Ende des Lichtleiters angeordnet ist und deren Zuleitung seitlich längs des Saugrohres geführt ist.This object is achieved according to the invention in that instead of one of the two light guides a light-sensitive electrical element, e.g. B. a photocell is provided on the transparent wall of the cap opposite the end of the Light guide is arranged and the lead laterally along the suction tube is.

Der Vorteil dieser Lösung besteht darin, daß auf den lichtabführenden Lichtleiter verzichtet werden kann, so daß sich die Lichtverluste und die Störeinflüsse auf die Hälfte verringern.The advantage of this solution is that on the light-dissipating Light guide can be dispensed with, so that the light losses and the interference reduce by half.

Eine derartige Lösung wir dann in betracht zu ziehen sein, wenn die Verwendung von verschiedenfarbigen Filtern im Strahlengang außerhalb der Sonde zur Objektivierung der Fruchtwasserverfärbung beabsichtigt ist.Such a solution will then have to be considered if the Use of different colored filters in the beam path outside the probe for Objective of the discoloration of the amniotic fluid is intended.

Die der Erfindung zugrunde liegende Aufgabe kann auch dadurch gelöst werden, daß statt des einen Lichtleiters ein licht-oder strahlungsempfindliches elektrisches Element und statt des anderen Lichtleiters eine elektrische Licht- oder Strahlur£S-quelle vorgesehen ist, wobei sich das Element und die Licht- -oder Strahlungsquelle an der durchsichtigen Wandung der Kappe gegenüberliegen und ihre elektrischen Zuleitungen seitlich längs des Saugrohres geführt sind.The object on which the invention is based can also be achieved in this way be that instead of a light guide a light or radiation sensitive electrical element and instead of the other light guide an electrical light or Strahlur £ S source is provided, whereby the element and the light -or Opposite radiation source on the transparent wall of the cap and their electrical leads are laterally guided along the suction pipe.

Mit dieser Lösung wird erreicht, aaß ganz auf Lichtleiter verzichtet werden kann, so daß Lichtverluste und Störeinflüsse allsoschaltet sind.With this solution it is achieved that there is no need for light guides can be so that light losses and interference are all switched on.

Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden naher beschrieben.Embodiments of the invention are shown in the drawing and are described in more detail below.

nie Sonde wird mit Hilfe eines bekannten Amnioskoptubus an die Fruchtblase herangefüht, 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 2. Dabei gelangt etwas Fruchtwasser in den Bereich der Vertiefung 4.Never probe is attached to the amniotic sac with the help of a known amnioscope tube brought up until the cap 2 rests against it. By suction via the suction tube 3 a small portion of the amniotic sac wall is sucked into the central one Well 4 of the cap 2. Some amniotic fluid gets into the area of the well 4th

Bei der Ausführungsform der Sonde gemäß Figur 1 wird durch einen Lichtleiter 6, der längs des Saugrohres 3 geführt ist, ber ein 900 Prisma 8 an der durchsichtigen Wandung der Kappe 2 Licht durch den Bereich der Vertiefung 4 hindurchgeschickt unO von einem lichtelektrischen Element 9 auf der gegenüberliegenden Seite ausgenommen, von wo aus die erzaugten elektrischen Werte über eine Leitung 10 einer nicht dargestellten Neßeinrichtung zugeführt werden.In the embodiment of the probe according to FIG. 1, a light guide is used 6, which is guided along the suction pipe 3, via a 900 prism 8 on the transparent one Wall of the cap 2, light is sent through the area of the recess 4 excepted from a photoelectric element 9 on the opposite side, from where the generated electrical values via a line 10 of a not shown Wetting device are supplied.

Die Figur 2 zeigt eine Sondenausführung, bei der eine Licht-oder Strahlungsquelle 11, die über eine Zuleitung 12 versorgt wird, in der Kappe 2 der Sonde angeordnet ist. Der übrige Aufbau der Sonde entspricht dem der ir. Figur 1 dargestellten Sonde.FIG. 2 shows a probe design in which a light or radiation source 11, which is supplied via a supply line 12, arranged in the cap 2 of the probe is. The rest The structure of the probe corresponds to that of FIG. 1 shown probe.
