Description

VORRICHTUNG ZUM ERWÄRMEN EINES GEGENSTANDS DEVICE FOR HEATING AN OBJECT
MITTELS WASSERBADBY WATER BATH
Die Erfindung betrifft eine Vorrichtung zum Erwärmen eines Gegenstands mittels Wasserbad, insbesondere zum Strecken von pathologischen bzw. histologischen Schnitten, insbesondere von Paraffinschnitten vor einer mikroskopischen Untersuchung, mit einem Gehäuse und einer in das Gehäuse eingesetzten Wanne, wobei das Wasserbad mittels einer Elektroheizung temperierbar ist.The invention relates to a device for heating an object by means of a water bath, in particular for stretching pathological or histological sections, in particular of paraffin sections before a microscopic examination, with a housing and a trough inserted into the housing, wherein the water bath can be tempered by means of an electric heater.
Gattungsbildende Vorrichtungen sind in den unterschiedlichsten Ausführungsformen aus der Praxis bekannt. Sie dienen zum Erwärmen bzw. Temperieren eines Wasserbads, wobei dieses wiederum zum Strecken von Paraffinschnitten im histologischen Labor eingesetzt wird.Generic devices are known in practice in a wide variety of embodiments. They are used for heating or tempering a water bath, which in turn is used for stretching paraffin sections in the histological laboratory.
Die aus der Praxis bekannten Vorrichtungen der gattungsbildenden Art sind insoweit problematisch, als die gewünschte Temperatur meist über mehrstufige Schalter nur in etwa vorgebbar ist. Nicht selten wird die Temperatur über ein externes Thermometer gemessen oder ist überhaupt keine Temperaturanzeige vorgesehen. Die bekannten Vorrichtungen sind daher in der Anwendung problematisch und haben nur einen geringen Bedienkomfort.The known from practice devices of the generic type are problematic insofar as the desired temperature is usually only about multi-stage switch specified. Not infrequently the temperature is measured by an external thermometer or no temperature display is provided at all. The known devices are therefore problematic in the application and have only a low ease of use.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Erwärmen eines Gegenstands mittels Wasserbad, insbesondere zum Strecken von pathologischen bzw. histologischen Schnitten, insbesondere von Paraffinschnitten vor einer mikroskopischen Untersuchung, derart auszugestalten und weiterzubilden, dass bei einfachster Konstruktion ein höchstes Maß an Betriebssicherheit bei hinreichend gutem Bedienkomfort realisiert ist.The present invention is therefore based on the object, a device for heating an object by means of a water bath, in particular for stretching pathological or histological sections, paraffin sections in particular before microscopic examination to design and further develop that with the simplest design a high degree of operational reliability is realized with sufficiently good ease of use.
Die voranstehende Aufgabe ist durch die Merkmale des Patentanspruchs 1 gelöst. Danach ist die gattungsbildende Vorrichtung dadurch gekennzeichnet, dass die Elektroheizung mindestens eine dem Boden der Wanne zugeordnet Heizplatte um- fasst und dass eine vorgebbare Wassertemperatur regelbar ist. Erfindungsgemäß umfasst die Elektroheizung mindestens eine dem Boden der Wanne zugeordnete Heizplatte. Somit wird unmittelbar der Wannenboden flächig beheizt. Entsprechend der Vorkehrung der Heizplatte ist eine vorgebbare Wassertemperatur regelbar. Dies bedeutet, dass über den Betrieb hinweg die Wassertemperatur über einen Temperatursensor ermittelt wird und die Heizung entsprechend geregelt wird. Somit ist gewährleistet, dass das Wasserbad stets die gewünschte Temperatur aufweist und zwar ungeachtet der Umgebungstemperatur, des Durchsatzes und der Betriebsdauer.The above object is solved by the features of claim 1. Thereafter, the generic device is characterized in that the electric heater comprises at least one of the bottom of the tub associated heating plate and that a predetermined water temperature can be regulated. According to the invention, the electric heater comprises at least one heating plate associated with the bottom of the tub. Thus, the bottom of the tub is heated directly. According to the provision of the heating plate, a predeterminable water temperature is adjustable. This means that over the operation, the water temperature is determined by a temperature sensor and the heating is regulated accordingly. This ensures that the water bath always has the desired temperature regardless of the ambient temperature, throughput and operating time.
In vorteilhafter Weise umfasst die Elektroheizung mindestens zwei oder mehrere Heizplatten, wobei der Bodenbereich der Wanne entsprechend sektioniert sein kann. Die Heizplatten können dabei gemeinsam oder einzeln aktiviert werden. Auch ist es denkbar, dass die Heizplatten in der Mitte des Bodenbereichs eine kreisförmige Gestalt und darum herum kreisringförmige Segmente umfassen. Auch hier ist eine gemeinsame oder einzelne Aktivierung entsprechend dem Energiebedarf möglich.Advantageously, the electric heater comprises at least two or more heating plates, wherein the bottom portion of the pan can be sectioned accordingly. The heating plates can be activated together or individually. It is also conceivable that the heating plates in the middle of the bottom area comprise a circular shape and annular segments around it. Again, a common or individual activation according to the energy requirement is possible.
Grundsätzlich ist es denkbar, dass die Heizplatten, ungeachtet ihrer konkreten Ausgestaltung, integrale Bestandteile des Bodens der Wanne sein können. Im Hinblick auf eine einfache Konstruktion ist es von Vorteil, wenn die Heizplatten von unten mit dem Boden der Wanne verbunden, vorzugsweise verklebt sind. Dabei ist es von ganz besonderem Vorteil, wenn die Heizplatten mittels eines Klebstoffs mit hoher Wärmeleitfähigkeit verklebt sind, um nämlich die Wärmeleitung in das zu beheizende Wasser hinein zu begünstigen.In principle, it is conceivable that the heating plates, regardless of their concrete design, can be integral components of the bottom of the tub. With regard to a simple construction, it is advantageous if the heating plates are connected from below to the bottom of the tub, preferably glued. It is of very particular advantage if the heating plates are bonded by means of an adhesive with high thermal conductivity, namely to promote the heat conduction into the water to be heated inside.
Des Weiteren ist es denkbar, dass die Seitenwandungen der Wanne mit Heizelementen versehen sind, wobei es sich bei diesen Heizelementen ebenso um Heizplatten, aber auch um Heizrohre, Heizkabel, etc. handeln kann.Furthermore, it is conceivable that the side walls of the tub are provided with heating elements, wherein these heating elements can also be heating plates, but also heating pipes, heating cables, etc.
Das Beheizen des Wasserbads wird dadurch begünstigt, dass die Wandung der Wanne im Bodenbereich so dünn wie möglich ausgeführt ist, vorzugsweise eine Dicke von etwa 1 mm aufweist. Mit anderen Worten sollte der Bodenbereich so dünn ausgeführt sein, dass er gerade noch hinreichend stabil ist, jedoch einen hervorragenden Wärmeübergang von der Heizeinrichtung bzw. den Heizelementen in das Wasser gewährleistet. In Bezug auf die Ausgestaltung bzw. Fertigung des Gehäuses ist es denkbar, dass dieses als monolithischer Block gefertigt ist. Dabei kann das Gehäuse aus einem Aluminiumblock gefertigt sein. Die Oberfläche des Gehäuses ist vorzugsweise hell eloxiert.The heating of the water bath is facilitated by the fact that the wall of the tub in the bottom area is made as thin as possible, preferably has a thickness of about 1 mm. In other words, the floor area should be made so thin that it is just barely stable, but ensures excellent heat transfer from the heater or the heating elements in the water. With regard to the design or production of the housing, it is conceivable that this is made as a monolithic block. In this case, the housing may be made of an aluminum block. The surface of the housing is preferably lightly anodized.
Die im Gehäuse angeordnete bzw. dort befestigte Wanne kann aus Aluminium gefertigt sein. Die Oberfläche der Wann kann ebenfalls eloxiert sein, wobei es sich hier anbietet, die Oberfläche der Wanne dunkel, insbesondere schwarz, zu eloxieren, um nämlich Reflexionen innerhalb der Wanne zu vermeiden.The arranged in the housing or fixed there well can be made of aluminum. The surface of the When can also be anodized, it being advisable to anodize the surface of the tub dark, especially black, namely to avoid reflections within the tub.
In ganz besonders vorteilhafter Weise weist die Wanne eine zumindest teilweise die Wanne umlaufende Ablagefläche zum Ablegen von Proben, Objektträgern, etc. auf. Dabei ist es denkbar, dass die Ablagefläche die Wanne insgesamt umläuft. Die Ablagefläche kann eine erhebliche Breite aufweisen, nämlich eine Breite im Bereich von 30 mm bis 70 mm, vorzugsweise von etwa 50 mm. Die Vorkehrung der Ablagefläche bietet der Bedienperson eine ganz erhebliche Sicherheit und Erleichterung bei der Arbeit.In a particularly advantageous manner, the tub has an at least partially the tub rotating storage area for storing samples, slides, etc. It is conceivable that the storage area rotates the tub altogether. The shelf may have a considerable width, namely a width in the range of 30 mm to 70 mm, preferably of about 50 mm. The provision of the shelf offers the operator a very significant safety and ease of work.
In weiter vorteilhafter Weise ist die Ablagefläche durch einen umlaufenden, gegenüber der Ablagefläche erhabenen äußeren Rand begrenzt, damit nämlich keine Flüssigkeit auf die Unterlage bzw. auf den Tisch gelangen kann.In a further advantageous manner, the support surface is limited by a peripheral, with respect to the shelf raised outer edge, namely, so that no liquid can get onto the surface or on the table.
Des Weiteren ist es denkbar, dass die Ablage oder der Rand eine Markierung für die Position eines AusVAblaufs aufweist, nämlich als Orientierung für die Bedienperson.Furthermore, it is conceivable that the tray or the edge has a mark for the position of a Auswablaufs, namely as an orientation for the operator.
Die Ablagefläche kann ebenfalls beheizt sein. Die Heizung der Ablagefläche kann unabhängig von der Heizung im Bodenbereich aktivierbar und regelbar sein. Wesentlich ist jedenfalls, dass auch die Ablagefläche zum Temperieren bzw. Trocknen darauf befindlicher Objekte dienen kann.The shelf can also be heated. The heating of the shelf can be activated and regulated independently of the heating in the floor area. In any case, it is essential that the storage surface can also serve for tempering or drying objects located thereon.
Das Gehäuse und/oder die Wanne können mit weiteren funktionalen Einrichtungen bzw. Einheiten ausgestattet sein. So ist es bspw. denkbar, dass die Wanne mit einer optischen und/oder elektrischen bzw. elektronischen Wasserstandsanzeige ausgestattet ist. Eine optische Wasserstandsanzeige könnte über ein von außerhalb des Gehäuses sichtbares Fenster in der Wanne realisiert sein. Eine elektrische bzw. elektronische Wasserstandsanzeige könnte über ein Display am Gehäuse realisiert sein.The housing and / or the tub may be equipped with other functional devices or units. For example, it is conceivable that the tub is equipped with an optical and / or electrical or electronic water level indicator. A visual water level gauge could be over from outside the housing visible window can be realized in the tub. An electrical or electronic water level indicator could be realized via a display on the housing.
Von weiterem Vorteil ist es, wenn die Wanne mit einer wahlweise aktivierbaren Beleuchtung, vorzugsweise mit einer Unterwasserbeleuchtung ausgestattet ist. Die Beleuchtung umfasst mindestens eine Diode als Leuchtmittel. In vorteilhafter Weise umfasst die Beleuchtung zwei unabhängig voneinander schaltbare Dioden, vorzugsweise zur Emission von weißem und von blauem Licht. Grundsätzlich ist es denkbar, dass die Beleuchtung als RGB-Beleuchtung mit einstellbaren Farben bzw. mit einstellbarer Wellenlänge ausgeführt ist. Die Beleuchtung ist vorzugsweise in den Seiten der Wanne ausgebildet, so dass ein Blenden der Bedienperson wirksam vermieden ist.Another advantage is when the tub is equipped with an optionally activatable lighting, preferably with an underwater light. The lighting comprises at least one diode as the light source. Advantageously, the illumination comprises two independently switchable diodes, preferably for the emission of white and blue light. In principle, it is conceivable that the illumination is designed as RGB illumination with adjustable colors or with an adjustable wavelength. The lighting is preferably formed in the sides of the trough, so that an aperture of the operator is effectively avoided.
Bereits zuvor ist erwähnt worden, dass das Gehäuse mit einer Anzeige bzw. mit einem Display ausgestattet sein kann. So könnte das Gehäuse eine vordere Sichtfläche mit einer Anzeige und mit separaten oder integrierten Bedienelementen aufweisen. Sofern die Bedienelemente in die Anzeige integriert sind, könnte die Anzeige, mit den Bedienelementen, als Touch-Panel ausgeführt sein.It has already been mentioned that the housing can be equipped with a display or with a display. Thus, the housing could have a front viewing surface with a display and with separate or integrated controls. If the controls are integrated into the display, the display, with the controls could be designed as a touch panel.
Im Gehäuse kann des Weiteren eine Elektronik zur Temperaturregelung und zur Regelung weiterer Parameter bzw. Größen vorgesehen sein. Es ist selbstverständlich, dass die Elektronik Signale über eine Sensorik bzw. einen Sender erhält, der in der Wandung der Wanne angeordnet bzw. dort vorgesehen ist. Jedenfalls wird die Temperatur auf einen vorgebbaren bzw. einstellbaren Wert geregelt, und zwar ungeachtet äußerer Einflüsse.In addition, electronics for temperature control and for regulating further parameters or variables may be provided in the housing. It goes without saying that the electronics receive signals via a sensor or a transmitter, which is arranged in the wall of the tub or provided there. In any case, the temperature is regulated to a predeterminable or adjustable value, regardless of external influences.
In weiter vorteilhafter Weise umfasst die Elektronik eine Notaus-Funktion dergestalt, dass die Heizung bei Unterschreiten eines vorzugsweise vorgebbaren unteren Wasserstandes in der Wanne deaktiviert wird. Auch ist es denkbar, dass bei Unterschreiten eines unteren Wasserstandes ein optisches und/oder akustisches Signal erfolgt, wonach ein Nachfüllen des Wassers erforderlich ist. Auch ist es denkbar, dass die Vorrichtung mit einem Wasseranschluss versehen ist, der den Wasserstand automatisch regelt. In einem solchen Fall wird die Füllmenge detektiert und kann ständig nachgespeist werden.In a further advantageous manner, the electronics comprise an emergency stop function in such a way that the heater is deactivated when it falls below a preferably predeterminable lower water level in the trough. It is also conceivable that falls below a lower water level, an optical and / or acoustic signal takes place, after which a refilling of the water is required. It is also conceivable that the device is provided with a water connection, the water level automatically regulates. In such a case, the capacity is detected and can be constantly fed.
In Bezug auf die Montage der Vorrichtung ist es von Vorteil, wenn die Wanne in das Gehäuse gesteckt und dort fixiert ist. Es bietet sich an, die Wanne von oben in das Gehäuse einzusetzen, wobei das Gehäuse dazu einen zur Auflage dienenden inneren Rand umfasst. Zur sicheren Montage ist die Wanne mit dem Gehäuse vorzugsweise von unten verschraubt. Von oberhalb der Vorrichtung sind im Rahmen einer solchen Ausgestaltung keinerlei Befestigungsmittel erkennbar.With respect to the mounting of the device, it is advantageous if the trough is inserted into the housing and fixed there. It is advisable to insert the trough from above into the housing, wherein the housing for this purpose comprises a serving for supporting inner edge. For safe installation, the tub is preferably bolted to the housing from below. From above the device, no fastening means are recognizable in the context of such a configuration.
Schließlich ist eine Bodenabdeckung zum bodenseitigen Verschließen des Gehäuses vorgesehen, wobei die Bodenabdeckung mit dem Gehäuse verschraubt ist. Vorzugsweise sind an den Verschraubungen Lagerpuffer zum sicheren Aufstellen der Vorrichtung vorgesehen.Finally, a bottom cover is provided for the bottom-side closing of the housing, wherein the bottom cover is screwed to the housing. Preferably, bearing buffers are provided for secure installation of the device at the screw connections.
