Description

Form zur Herstellung von Blöcken aus histologischen Einbettungsmassen Zur Herstellung von Gewebsschnitten mit dem Mikrotom werden in der histologischen Technik Gewebsstücke in eine feste Einbettungsmasse wie beispielsweise Paraffin oder Wachs eingebettet.Mold for the production of blocks from histological embedding materials For the production of tissue sections with the microtome the histological Technique Pieces of tissue in a solid embedding material such as paraffin or wax embedded.

Diese histologische Einbettungsmasse wird erwärmt und in flüssigem Zustand in Einbettungsrahmen aus Metall eingdfilllt, die auf einem Metallboden verschiebbar aufgesetzt sind. Die flüssig eingefüllte Masse tritt vers-tä'ndlicherweise an den verschiebbaren Verbindungsstellen der Rahmen solange aus, bis sie hier erstarrt ist. Andererseits erstarrt die Masse an den Metallwänden und dem Metallboden verhältnismäßig rasch. Infolgedessen kann man die Gewebsstücke nicht mehr auf den Boden des Einfüllrahmens bringen, wie es erwünscht wäre, um sie in der Bodenebene anzuordnen, die beim Mikrotomschnitt die Schnittebene bildet.This histological embedding material is heated and in liquid Condition filled in embedding frame made of metal, which can be moved on a metal base are put on. The liquid filled mass accidentally hits the sliding connection points of the frame until it solidifies here is. On the other hand, the mass solidifies relatively on the metal walls and the metal base quickly. As a result, the pieces of tissue can no longer be placed on the bottom of the filling frame bring them as it would be desired to place them in the plane of the ground, which is the microtome cut forms the cutting plane.

Die Neuerung betrifft eine Form zur Herstellung von Blöcken aus einer histologischen Einbettungsmasse, welche die Schwierigkeiten und Nachteile der bekannten Formen vermeidet. Diese Form besteht neuerungsgemäß aus einer kastenförmigen Gummiwanne, deren Gummi eine sehr geringe Adhäsion an der eingefüllten Einbettungsmasse hat. Ein Gummi mit dieser Eigenschaft ist Silikongummi.The innovation relates to a form for the production of blocks from a histological embedding material, which avoids the difficulties and disadvantages of the known forms. This form exists according to the new from a box-shaped rubber tub, its rubber has very little adhesion to the embedding compound. One rubber with this property is silicone rubber.

Die in eine solche Gummiwanne eingefüllte flüssige Einbettungmasse kann nun nicht mehr aus dem Behälter entweichen. Sie bleibt darin auch am Boden solange flüssig, bis die Gewebsstücke am Boden wunschgemäß angeordnet sind.The liquid embedding compound poured into such a rubber tub can no longer escape from the container. She stays on the ground in it Liquid until the pieces of tissue are arranged as desired on the floor.

Die Wände und der Boden der Wanne sind sehr flexibel. Infolgedessen läßt sich der in der Wanne erkaltete Block oder der durch beliebig in die flüssige Einbettungsmasse eingesetzte Querwände in Böckchen unterteilte Block bequem aus der Wanne herauslösen. Die Zeichnung zeigt beispielsweise eine aus Silikongummi gefertigte Wanne.The walls and bottom of the tub are very flexible. Consequently the block, which has cooled down in the tub or through, can be poured into the liquid Embedding compound, the transverse walls are conveniently divided into blocks, divided into brackets remove the tub. For example, the drawing shows one made of silicone rubber manufactured tub.
