Description

Bei Dampf-Druck-Sterilisiereinrichtungen, welche aus einem Autoklav und einem diesen speisenden Dampfkessel bestehen, ist der Dampfkessel vom Sterilisierraum durch ein Absperrorgan getrennt. In the case of steam pressure sterilization devices that come from an autoclave and a steam boiler that feeds this, the steam boiler is from the sterilization room separated by a shut-off device.

In der Regel hat der Autoklav einen Doppelmantel, welcher aus dem gleichen, dazugehörigen Dampfkessel vorgeheizt wird. Es sind weiter Einrichtungen bekanntgeworden, bei denen die Heizfläche des Dampfkessels derart zur Wärmeübertragung ausgenutzt wird, daß entweder der Zwischenraum in dem Doppelmantel als Dampfkesselraum oder auch nur ein Teil der Dampfkesselfläche zur Ausbildung des Sterilisierraumes benutzt wird. Es ist bei Sterilisatoren dieser Art schwierig, während des Trocknungsvorganges die Wärme aus den Heizflächen in das Gut zu leiten, weil zwischen ihnen ein luftverdünnter Raum schlechter Wärmeleitfähigkeit liegt. Bei den bekannten Einrichtungen horizontaler Bauart mit zylindrischem Autoklav wird der gesamte Sterilisierraumquerschnitt nicht hinreichend vom Sterilisiergut ausgefüllt, der ungenutzte Raum ist verhältnismäßig groß.As a rule, the autoclave has a double jacket, which consists of the the same, associated steam boiler is preheated. There are further institutions became known, in which the heating surface of the steam boiler in such a way for heat transfer is exploited that either the space in the double jacket as a boiler room or only part of the steam boiler surface to form the sterilization room is used. It is difficult with sterilizers of this type during the drying process to conduct the heat from the heating surfaces into the property, because between them there is an air-diluted Room with poor thermal conductivity. In the known facilities more horizontal The entire cross-section of the sterilization room is not designed with a cylindrical autoclave Sufficiently filled with items to be sterilized, the unused space is proportionate great.

Die Erfindung beseitigt diese Mängel. Sie ist in der Zeichnung beispielsweise im Schnitt dargestellt. The invention overcomes these shortcomings. It is in the drawing, for example shown in section.

Ein zylindrischer liegender Dampikessel 1 trägt in Form einer Durchdringung in der Längsachse einen zweiten liegenden, als Sterilisierraum dienenden Körper 2, so daß der Mantel des Dampfkessels in den Sterilisierraum hineinragt. In dem Sterilisierraum ist etwa im Scheitelpunkt des Dampfkesselmantels ein Auflageblech 3 eingebaut, welches den Aufnahmebehälter des Sterilisiergutes 4 trägt. Der den Sterilisierraum bildende zylindrische Mantel 2 ist in üblicher Weise durch ein druckfeste Tür verschließbar. Der Sterilisierdampf tritt über das Ventil 5 in den Sterilisierraum ein und strömt über das Ventil 6 ab. Die Wirkungsweise ist hierbei folgende: Das Sterilisiergut wird in einem Behälter 4 in den Sterilisierraum eingebracht und die Tür des Sterilisierraumes druck- und vakuumdicht verschlossen. Über das Ventil 6 wird zunächst die Luft künstlich, etwa durch eine Vakuumpumpe, abgesaugt. Ist der Sterilisierraum evakuiert, so wird das Ventil 5, welches die Verbindung zwischen dem Dampfkessel und dem Sterilisierraum herstellt, geöffnet und somit das Sterilisiergut unter Dampf gesetzt. Nach Beendigung der Dampfeinwirkung wird das Ventil 5 geschlossen und die Dampfschwaden über das Ventil 6 aus dem Sterilisierraum entfernt. Bei dem nun stattfindenden Trocknungsvorgang wird die Wärme gemäß der vorliegenden Erfindung aus der Dampfkesselfläche unter Wärmeleitung in das Sterilisiergut gebracht.A cylindrical horizontal steam boiler 1 carries in the form of a penetration in the longitudinal axis a second lying body serving as a sterilization area 2, so that the jacket of the steam boiler protrudes into the sterilization room. By doing The sterilization room is a support plate approximately at the apex of the steam boiler jacket 3 installed, which carries the receptacle for the items to be sterilized 4. The den The cylindrical jacket 2 forming the sterilization space is in the usual way by a pressure-resistant Lockable door. The sterilization steam enters the sterilization room via valve 5 in and flows out via valve 6. The mode of action is as follows: The The items to be sterilized are placed in a container 4 in the sterilization room and the The door of the sterilization room is closed pressure- and vacuum-tight. Via valve 6 the air is initially sucked out artificially, for example by a vacuum pump. Is the Sterilization room evacuated, so the valve 5, which is the connection between the steam boiler and the sterilization room, opened and thus the items to be sterilized put under steam. After the end of the action of steam, the valve 5 is closed and the steam plumes are removed from the sterilization room via the valve 6. In which The drying process now taking place is the heat according to the present invention brought from the steam boiler surface under heat conduction into the items to be sterilized.

Der Wärmefluß geht hierbei einesteils direkt über den Mantel des Sterilisierbehälters und andererseits durch unmittelbaren Kontakt in das das Sterilisiergut tragende Auflageblech. Aus dem Auflageblech wird die Wärme wiederum durch Kontaktanlage in das Sterilisiergut, z. B. Instrumente, oder in den das Sterilisiergut aufnehmenden Behälter direkt geleitet.The heat flow goes partly directly over the jacket of the sterilization container and on the other hand through direct contact with the one carrying the items to be sterilized Support plate. The heat is in turn from the support plate through contact system in the items to be sterilized, e.g. B. instruments, or in the receiving the items to be sterilized Container piped directly.
