摘要: The invention relates to an extrusion head for the continuous extrusion of a multilumen medical tube, consisting of a monolithic sleeve and a mandrel embedded therein, characterised in that the mandrel consists of a first part (4a) and a second part (4b), where the first part (4a) of the mandrel is provided with an external thread and with fitter openings arranged circumferentially, in which the needles (5) are fixed, inside the first part (4a) of the mandrel an air supply channel is located, at the end of which there is a threaded hole for screwing in a fastening screw (6) immobilising the needles (5), the second part (4b) of the mandrel is provided with an internal thread matching the external thread of the first part (4a) of the mandrel. The invention also relates to a method for manufacturing a multilumen medical tube, characterised in that the head according to invention is mounted to the extruder, then a plastic is loaded into an extruder, mixed and pushed through the extruder screw while it is heated, then said plastic is extruded through the gap formed between the monolithic sleeve (3) and the mandrel assuming the shape of said gap, then the formed tube is successively pulled through the extruder, guided through the cooling bath with coolant and cut to a pre-set length. The invention also relates to a multilumen disposable medical tube with reduced weight, characterised by a diameter of 1.3 to 12 mm

摘要: Die Erfindung betrifft ein Verfahren zur Herstellung eines Extrusionswerkzeuges (1), welches zur Bildung eines Extrudates geeignet ist, indem plastisches Material an einer ersten Seite (13) in das Extrusionswerkzeug (1) gepresst wird, wonach das plastische Material nach einer Umformung an einer zweiten Seite (14) aus dem Extrusionswerkzeug (1) austritt, wobei in die erste Seite (13) eines Körpers (2) Einlassöffnungen (3) eingebracht werden, wobei in die zweite Seite (14) des Körpers (2) Schlitze (4) eingebracht werden, welche die Einlassöffnungen (3) verbinden. Um ein Extrusionswerkzeug (1), welches zur Herstellung eines Trägers mit günstigem Verhältnis von Oberfläche zu Volumen und gleichmäßiger Verteilung eines Strömungswiderstandes geeignet ist, auf einfache und effiziente Weise herstellen zu können, ist erfindungsgemäß vorgesehen, dass in die zweite Seite (14) zumindest eine Vertiefung (5) eingebracht wird, welche mit den Schlitzen (4) und den Einlassöffnungen (3) verbunden ist, wonach in der Vertiefung (5) ein Element angeordnet wird, sodass ein Querschnitt des mit dem Extrusionswerkzeug (1) gebildeten Extrudates durch eine Geometrie der Schlitze (4), eine Geometrie der Vertiefungen (5) und eine Geometrie des Elementes zumindest teilweise definiert wird.
Weiter betrifft die Erfindung ein Extrusionswerkzeug (1).-

摘要: The purpose of the present invention is to prevent the fouling of polysilicon with a resin sheet so that the polysilicon is effectively prevented from being contaminated due to the resin sheet. The antifouling method for polysilicon according to the present invention comprises using a tube-shaped resin sheet having an inner surface and an outer surface to prevent the fouling of polysilicon, characterized in that the tube-shaped resin sheet or a resin sheet cut out of the said tube-shaped resin sheet is held, with the inner surface being kept in an unexposed state, and the inner surface is exposed just before use and brought into contact with the polysilicon.
