Description

Elektrisch beheizter und gesteuerter Sterilisator für ärztliche Instrumente Die Erfindung betrifft einen Sterilisator für ärztliche Instrumente, der aus einem mit Wasser gefüllten Gefäß besteht, das elektrisch beheizt wind und in welchem die Instrumente gekocht werden. Bei einem solchen Apparat ist es wichtig, die elektrische Heizvorrichtung in Abhängigkeit zu bringen von der Standhöhe des Wassers im Kochgefäß, derart, daß bei vollgefülltem Gefäß die ganze. Heizvorrichtung eingeschaltet ist, während bei geringerer Füllung nur ein Teil der Heizvorrichtung arbeitet und bei Unterschreitung einer Mindestfüllung die Heizvorrichtung ganz ausgeschaltet wird. Dabei müssen gleichzeitig-entsprechend sichtbare oder hörbare Signale gegeben werden, so daß der Arzt oder die den Apparat bedienende Person rechtzeitig durch Nachfüllen den Wasserinhalt ergänzen kann oder aber sehen kann, daß der Apparat nicht mehr beheizt wird.Electrically heated and controlled sterilizer for medical instruments The invention relates to a sterilizer for medical instruments, which consists of a consists of a vessel filled with water, which is electrically heated and in which the Instruments to be boiled. In such an apparatus it is important to have the electrical Bringing the heating device depending on the level of the water in the cooking vessel, such that when the vessel is full the whole. Heating device is switched on, while with a lower filling only part of the heating device works and at If the filling drops below a minimum, the heating device is switched off completely. At the same time, correspondingly visible or audible signals must be given, so that the doctor or the person using the device can refill it in good time can supplement the water content or can see that the apparatus is no longer is heated.

Eine solche Vorrichtung ist in Abb. i im Längsschnitt, in Abb. 2 in teilweisem Querschnitt dargestellt. Das Sterilisiergefäß wird durch mehrere, hier zwei, Heizkörper a und b beheizt, die bei vollständig gefülltem Gefäß beide wirksam sind. In dem Gefäß sind oben und unten zwei isolierte plattenförmige Elektroden g und la angeoridnet, vor denen sich ein Schutzblech i befindet, welches dafür sorgt, daß die in die Schale k eingelegten Instrumente keinen Kurzschluß machen können. Die Beheizung selbst erfolgt durch Kraftstrom vom Leitungsnetz aus, während die Steuerung der Heizkörper und Betätigung der Signale durch einen Niederspannungswechselstrom erzielt wird, der mittels eines Kleintransformators c vom Netz abgenommen wird. Dadurch wird erreicht, daß alle Teile, mit denen man beim Gebrauch in Berührung kommen kann, eine niedrige und, unschädliche Spannung besitzen, so daß jeder Unglücksfall bei Benutzung des Apparates ausgeschlossen ist. Es handelt sich hierbei im wesentlichen um Spannungen von 4 bis 2o Volt.Such a device is shown in Fig. I in longitudinal section, in Fig. 2 in partial cross-section. The sterilization vessel is heated by several, here two, heating elements a and b , which are both effective when the vessel is completely full. Two insulated plate-shaped electrodes g and la are arranged above and below in the vessel, in front of which there is a protective plate i, which ensures that the instruments placed in the bowl k cannot short-circuit. The heating itself is carried out by power current from the mains, while the control of the radiators and actuation of the signals is achieved by a low-voltage alternating current, which is taken from the network by means of a small transformer c. This ensures that all parts with which one can come into contact during use have a low and harmless voltage, so that any accidents when using the device are excluded. These are essentially voltages of 4 to 20 volts.

Die Schaltung ist nun so angebracht. daß bei Füllung des Gefäßes mit Wasser bis an die Elektrode g beide Heizkörper eingeschaltet sind. Sinkt bei dauernder Beheizung der Wasserspiegel infolge Verdampfung unter die Elektrode g (s. Abb. i), so wird der Heizkörper b durch elektromagnetische Auslösung des Hebels e ausgeschaltet, so daß nur noch der Heizkörper a arbeitet. Sobald der Wasserspiegel bis unter die Elektrode h sinkt, wird auch der Hebel f ausgeschaltet, so daß nunmehr auch der Heizkörper a stromlos ist und die Heizung vollständig abgestellt ist.The circuit is now attached. that when filling the vessel with Water until both heating elements are switched on at the electrode g. Decreases with constant Heating of the water level as a result of evaporation under the electrode g (see Fig. I), the radiator b is switched off by electromagnetic triggering of the lever e, so that only the radiator a works. As soon as the water level is below the Electrode h sinks, the lever f is also switched off, so that now also the Radiator a is de-energized and the heating is completely switched off.

Um den Füllungszustand des Apparates dauernd überwachen zu können, sind den Hebeln e -und f die Lampen L und in parallel geschaltet, so daß beim öffnen eines Hebels die entsprechende Lampe aufleuchtet. Es ist also an den Lampen sofort zu erkennen, ob der Apparat vollgefüllt, halb gefüllt oder leer ist. Dabei können die Lampen smangeordnet sein, daß der operierende Arzt sie bequem vor Augen hat und ohne weiteres sich davon überzeugen kann,- daß die Instrumente ordnungsmäßig sterilisiert werden.In order to be able to continuously monitor the filling status of the apparatus, the levers e and f, the lamps L and in are connected in parallel so that the corresponding lamp lights up when a lever is opened. You can immediately tell from the lamps whether the device is full, half full or empty. The lamps can be arranged so that the operating doctor has them comfortably in front of his eyes and can easily convince himself that the instruments are properly sterilized.
