Description
Die Erfindung betrifft einen Gewebe-Einbettautomaten nach dem Oberbegriff des Anspruchs 1.The invention relates to a tissue embedding machine according to the preamble of claim 1.
Mittels Gewebe-Einbettautomaten werden Gewebeproben einer automatisch ablaufenden, mehrstufigen Bearbeitung in Behandlungsbehältern unterzogen, um die Proben zu entwässern und zu fixieren.Tissue samples are subjected to automatic, multi-stage processing in treatment containers by means of tissue embedding machines in order to dehydrate and fix the samples.
Die aufgrund Probendurchmessers und der Probenbeschaffenheit für den Behandlungsvorgang notwendige Verweildauer in den Behandlungsbehältern begrenzt die Anzahl der in einer Zeiteinheit behandelbaren Gewebeproben und schränkt die Möglichkeiten einer Bearbeitung mehrerer, verschieden schnell zu bearbeitender, Probenmengen ein. Um die Anzahl der in einer Zeiteinheit behandelbaren Gewebeproben zu erhöhen und probenbedingt verschieden schnell ablaufende Bearbeitungsvorgänge in beliebiger Reihenfolge zu ermöglichen, könnte die Anzahl der im Gewebe-Einbettautomaten vorhandenen Behandlungsbehälter erhöht werden, so dass mehrere zeitlich parallel laufende Behandlungen durchgeführt werden können, oder es konnten mehrere Gewebe-Einbettautomaten gleichzeitig eingesetzt werden. In beiden Fallen steigt der Platz und Kostenbedarf etwa linear mit der Anzahl der gleichzeitig zu behandelnden Gewebeproben.The residence time in the treatment containers, which is necessary for the treatment process on the basis of the sample diameter and the sample properties, limits the number of tissue samples that can be treated in one time unit and limits the possibilities of processing a plurality of sample volumes that can be processed at different rates. In order to increase the number of tissue samples that can be treated in a time unit and to allow samples to run in different orders in different orders, the number of treatment containers present in the tissue embedding machine could be increased so that several simultaneous treatments could be performed or could be performed several tissue embedding machines are used simultaneously. In both cases, the space and cost requirements increase approximately linearly with the number of tissue samples to be treated simultaneously.

Der Erfindung liegt die Aufgabe zugrunde, einen Gewebe-Einbettautomaten zu schaffen, der es ermöglicht, die Anzahl der in einer Zeiteinheit behandelbaren Gewebeproben ohne Steigerung der Anzahl der vorhandenen Behandlungsbehälter zu erhöhen, und zugleich eine kontinuierliche Beschickbarkeit, bspw. mit unterschiedlichen Probendurchmessern, gewährleistet bleibt, ohne besondere Anforderungen an die Reihenfolge der Proben zu stellen.The invention has for its object to provide a tissue-Einbettautomaten, which makes it possible to increase the number of tissue samples treatable in a unit time without increasing the number of existing treatment containers, and at the same time a continuous feedability, eg. With different sample diameters, guaranteed without placing special demands on the order of the samples.
Diese Aufgabe wird bei einem Gewebe-Einbettautomaten nach dem Oberbegriff des Anspruchs 1 durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved in a tissue-embedding machine according to the preamble of claim 1 by the features stated in the characterizing part of claim 1.
Die bei der Erfindung am Behandlungsbehälter angeordnete Ultraschallquelle verkürzt die nötige Behandlungszeit der Gewebeproben in zweierlei Weise.The ultrasound source arranged on the treatment container in the invention shortens the necessary treatment time of the tissue samples in two ways.
So dient die Ultraschallquelle als homogene, trägheitslos arbeitende Heizquelle, indem die eingekoppelte Ultraschallenergie von der Behandlungsflüssigkeit sowie dem Gewebe absorbiert wird. Die für die jeweilige Behandlungsflüssigkeit optimale Betriebstemperatur wird so nach Einsetzen eines Umgebungstemperatur aufweisenden Behandlungsbehälters mit Gewebeproben oder Auffüllen kalter Behandlungsflüssigkeit schneller erreicht als mit einer konventionellen Heizquelle, die ihre Energie nur durch Wärmeleitung über die Behälterwandung und anschließend durch Strömungsumwälzung der Behandlungsflüssigkeit einkoppelt.Thus, the ultrasound source serves as a homogeneous, inertially operating heating source by absorbing the coupled-in ultrasonic energy from the treatment liquid and the tissue. The optimal for the respective treatment liquid operating temperature is achieved after inserting an ambient temperature treatment container with tissue samples or filling cold treatment liquid faster than with a conventional heat source, which couples their energy only by heat conduction through the tank wall and then by flow circulation of the treatment liquid.
Weiterhin sorgen die Ultraschallschwingungen für ein aktives Eindringen der Behandlungsflüssigkeit ins Gewebe, wodurch die Behandlung wesentlich schneller abläuft als bei der sonst üblichen Diffusion, wobei die morphologische Struktur der Zellen optimal erhalten bleibt.Furthermore, the ultrasonic vibrations ensure an active penetration of the treatment liquid into the tissue, as a result of which the treatment proceeds much faster than in the otherwise usual diffusion, whereby the morphological structure of the cells is optimally maintained.
Über eine Schwingungsanregung mittels Ultraschall, statt einer direkten Einspeisung in die Gewebeproben mittels Mikrowellenstrahlung, wird eine homogenere Verteilung der Ultraschallenergie im gesamten Behandlungsbehälter erzielt und so Gewebeschädigungen durch punktuelle Überhitzung (HotSpots) vermieden.A vibration excitation by means of ultrasound, instead of a direct feed into the tissue samples by means of microwave radiation, a more homogeneous distribution of the ultrasonic energy is achieved throughout the treatment container, thus avoiding tissue damage by selective overheating (HotSpots).
Ferner umfasst der Behandlungsbehälter eine temperaturgeregelte Heizung zur Energiezufuhr und zur gesteuerten Energieabfuhr wird das Füll- und Entleersystems für die Behandlungsflüssigkeit genutzt.Furthermore, the treatment container comprises a temperature-controlled heating for supplying energy and for controlled energy dissipation, the filling and emptying system is used for the treatment liquid.
Durch die Kombination aus Ultraschallquelle als Heizquelle und Füll- und Entleersystems als Energieabfuhr lässt sich eine sehr schnell arbeitende Regelung erzielen, die für ein schnelles Gleichgewicht zwischen zugeführter und abgeführter Wärmeenergie sorgt und somit die Einhaltung einer engtolerierten Betriebstemperatur der Behandlungsflüssigkeit unter betriebsüblichen Bedingungen ermöglicht.The combination of ultrasound source as a heat source and filling and emptying system as energy dissipation can be a very fast-acting control achieve that provides a fast balance between supplied and dissipated heat energy and thus allows compliance with a tolerated operating temperature of the treatment liquid under normal operating conditions.
Die Verwendung mehrerer Behandlungsbehälter ermöglicht die gleichzeitige Bearbeitung auch durch die Probenbeschaffenheit bedingt unterschiedlich schnell ablaufender Behandlungsvorgänge in beliebiger Reihenfolge.The use of multiple treatment containers allows the simultaneous processing also due to the nature of the sample due to different speed expiring treatment operations in any order.
Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels beschrieben, das in der Zeichnung dargestellt ist.The invention will be described with reference to an embodiment shown in the drawing.
