Description

Beschreibung t Die Erfindung befasst sich mit einer Abschmelzvorrichtung filr Ampullen.Description t The invention is concerned with a melting device filr ampoules.

Es ist bekannt, mit Trockengut gefällte Ampullen in Gefriertrocknungsanlagen nach Abschluss des Trocknungsprozesses mit Pfropfen gu verschliessen. Abgesehen davon, daß für einen- solchen Verschluss der Ampullen eine komplizierte mechanische Einrichtung im Inneren der Trocknungskammer notwendig ist, bietet der Verschluß mittels Pfropfen keine unbedingte Sicherheit für die Erhaltung der Sterilität des Trocknungsgutes. Ein steriler Verschluss der Ampullen lässt sich vielmehr nur durch Zuschmelzen der Ampullen erreichen, was mit den bisher üblichen Zuschmelzverfahren in einer vakuumdicht geschlossenen Kammer gar nicht oder nur unter sehr großen Schwierigkeiten möglich war Die Erfindung hat es sich zur Aufgabe gestellt, eine Abechmelzl vorrichtung für in vakuumdicht geschlossenen Kammern befindliche Ampullen zu schaffen Sie benutzt zur Erhitzung der Ampullen~ spitze Energiestrahler welche weder Sauerstoff benötigen noch Verbrennungsgase abgeben, durch welche das Trocknungsgut geschädigt werden könnte. Als Mittel der Wahl kommen daher nur elektrisch beheizte Wärmestrahler oder Uochfrequenzstrahler in Betracht, deren Strahlung mit an sich bekannten Mitteln in einen Brennpunkt vereinigt wird. Zum Zuschmelzen wird dann Jede Ampulle in einen solchen Brennpunkt gebracht, wo genügend Wärmeenergie zur Verfügung seht, um die Ampullen sicher zuschmelzen zu können Die Erfindung, eine Vorrichtung zum Verschliessen von in vakuumdicht geschlossenen Kammern befindlichen Ampullen durch Zuschmelzen, ist dadurch gekennzelchnet, daß über den in an sich bekannter Weise in einem Gestell angeordneten Ampullen eine oder mehrere Energiequellen angebracht ist/sind, deren Strahlung mit an sich bekannten Mitteln in einem oder mehreren Brennpunkt/en vereinigt ist, und welcher/welche gegenüber den Ampullen derart in den drei Raumkoordinaten verschiebbar ist/sind, daß jede Ampulle in den Brennpunkt der Energiequelle/einer der Energiequellen gebracht werden kann. Solche Energiequellen können Wärmestrahler oder Hochfrequenzstrahler sein.It is known to use ampoules precipitated with dry material in freeze-drying systems after the drying process has been completed, seal it with a plug. Apart from that from the fact that for such a closure of the ampoules a complicated mechanical The closure provides a facility inside the drying chamber by means of grafting no unconditional security for the maintenance of the sterility of the Goods to be dried. A sterile closure of the ampoules can only be through Achieve melting of the ampoules, what with the previously usual melting process in a vacuum-tight closed chamber not at all or only with great difficulty was possible The invention has set itself the task of a Abechmelzl device You used to create ampoules located in vacuum-tight closed chambers For heating the ampoule-point energy emitters which do not require oxygen still emit combustion gases, which damage the items to be dried could. The only means of choice are therefore electrically heated radiant heaters or High frequency radiators into consideration, their radiation by means known per se is united in one focal point. Each ampoule is then melted into a brought to such a focal point, where there is sufficient heat energy available for the To be able to fuse ampoules safely. The invention, a device for closing of ampoules located in vacuum-tight closed chambers by melting, is characterized in that over the in a known manner in a frame arranged ampoules one or more energy sources is / are attached, their Radiation combined with means known per se in one or more focal points is, and which / which opposite the ampoules in such a way in the three spatial coordinates is / are displaceable that each ampoule in the focus of the energy source / one the energy sources can be brought. Such energy sources can be radiant heaters or high frequency radiators.

In einer anderen Ausführungsforin können die Strahler fest und die Ampullen diesem/n gegenüber verschiebbar angeordnet sein. Die Vor richtung kann mehrere linear nebeneinander angeordnete Strahler vorgesehen sein.In another embodiment, the radiators can be fixed and the Ampoules can be arranged displaceably opposite this / n. The device can several radiators arranged linearly next to one another can be provided.

Es kann schliesslich vorteilhaft sein, die Kammer vor dem Zuschmelzen der Ampullen mit einem inerten Gas, z.B. Stickstoff, zu füllen.Finally, it can be advantageous to close the chamber before melting it down fill the ampoules with an inert gas, e.g. nitrogen.

Die Zeichnung zeigt in den Figuren 1 und 2 ein Ausführungsbeispiel der Erfindung.The drawing shows an exemplary embodiment in FIGS. 1 and 2 the invention.

In ihnen ist 1 die Trocknungskammer einer Gefriertrocknungsanlage, 2 das die Ampullen 3 aufnehmende Gestell. Über diesem sind in den drei Rauikoordinaten verschiebbar die Strahler 4 angeordnet,deren Strahlung mittels strablungsleitender Elemente 3 in den Brennpunkten 6 vereinigt ist. Durch Betätigung der Verstellvorrichtung 7 lassen sich die Spitzen der Ampullen in die Brennpunkte bringen, in welchen das Zuschmelzen erfolgt.In them 1 is the drying chamber of a freeze dryer, 2 the frame receiving the ampoules 3. Above this are in the three rough coordinates displaceably arranged the radiators 4, their radiation by means of strablungsleitender Elements 3 in the focal points 6 is united. By actuating the adjustment device 7, the tips of the ampoules can be brought into the focal points in which the Melting takes place.
