Description

Vorwärmgerät für StethoskopPreheating device for stethoscope
Stand der TechnikState of the art
Die vorliegende Erfindung geht aus von Stethoskopen wie sie in ärztlichen Praxen Verwendung finden. Bevor ein Arzt ei¬ nen Patienten abhört, sollte er den Stethoskopkopf etwas anwärmen, da die Patienten, insbesondere Kinder sonst die kalte Abhorflache des Stethoskopkopfes bei Kontakt mit der Haut als unangenehm empfinden. Üblicherweise geschieht das Anwärmen, wenn überhaupt, nur kurz mit der Handfläche des Arztes. Dies ist jedoch vielfach nicht ausreichend.The present invention is based on stethoscopes as they are used in medical practices. Before a doctor listens to a patient, he should warm the stethoscope head a little, since the patients, especially children, otherwise feel the cold Abhorflache of the stethoscope head in contact with the skin as unpleasant. Usually, the warming, if any, occurs only briefly with the palm of the doctor. However, this is often insufficient.
Vorteile der Erfindung Im folgenden wird Bezug zu den Ansprüchen genommen.Advantages of the Invention Reference will now be made to the claims.
Mit den Maßnahmen des Anspruches 1 wird erreicht, dass der Kopf eines Stethoskops, mit seinen Flächen, die in Kontakt mit der Haut des menschlichen Körpers kommen können, in an¬ genehm vorgewärmten Zustand ist, wenn ein behandelnder Arzt das Stethoskop greift, um einen Patienten abzuhören.It is achieved with the measures of claim 1 that the head of a stethoscope, with its surfaces which can come into contact with the skin of the human body, is in an an¬ preheated condition when a doctor treating the stethoscope reaches out to a patient listen.
In den Unteransprüchen sind vorteilhafte Ausgestaltungen Weiterbildungen und Verbesserungen des jeweiligen Gegens¬ tandes der Erfindung angegeben.In the subclaims advantageous refinements developments and improvements of the respective Gegens¬ tandes of the invention are given.
Durch ein Paar von gegenüberliegenden Wärmeleitplatten, bei denen eine unter Vorspannung in Richtung der anderen ge¬ drückt wird, können auch beide Abhörflächen von entspre¬ chend ausgerüsteten Stethoskopköpfen vorgewärmt werden. oBy a pair of opposite heat conducting plates, in which one is pressed under bias in the direction of the other, both listening surfaces can be preheated by stethoscope heads equipped accordingly. O
Die Vorrichtung kann auch mehrere Einschubfächer besitzen. Sie funktioniert mit Gleichstrom bei einer Versorgungsspan¬ nung von 12 Volt über ein handelsübliches Netzteil, und E- lektronikbauteilen, die eine angenehme Temperatur auf den Wärmeleitplatten erzeugen.The device may also have several slots. It works with direct current at a supply voltage of 12 volts via a commercially available power supply unit, and electronic components which generate a comfortable temperature on the heat conducting plates.

Beschreibung von AusführungsbeispielenDescription of exemplary embodiments
Das erfindungsgemäße Vorwärmgerät des ersten Ausführungs¬ beispiels enthält ein Gehäuse 5 mit einer Mehrzahl von Ge¬ häusefüßen zum Abstellen des Gerätes beispielsweise auf ei- ner Tischfläche. Das Gehäuse 5 hat einen Bodenbereich, der ein frontseitiges Einschubfach für den Stethoskopkopf, und ein rückseitiges, geschlossenes Fach bildet zur Aufnahme von Elektronikbauteilen 6. Im rückseitigen Bereich befindet sich ein Elektroanschluss für ein Netzgerät mit 12 Volt Ausgangsspannung, die das die weiteren elektronischen Bau¬ teile im Vorwärmgerät mit der notwendigen elektrischen E- nergie versorgt. Ein im wesentlichen vertikal verlaufenderThe preheater according to the invention of the first Ausführungs¬ example includes a housing 5 with a plurality of Ge housing feet for parking the device, for example on a table surface. The housing 5 has a bottom portion, which forms a front-side insertion compartment for the stethoscope head, and a rear, closed compartment for receiving electronic components 6. In the rear area there is an electrical connection for a power supply with 12 volts output voltage, the other electronic Bau¬ parts in the preheater with the necessary electrical nergy supplies. A substantially vertically extending
Steg im innern des Vorwärmgerätes trennt das Einschubfach von dem rückwärtigen Bereich.Footbridge in the interior of the preheater separates the insertion compartment from the rear area.
Das Einschubfach wird nach unten und oben durch Wärmeleit¬ platten 2 begrenzt, die von den Elektronikbauteilen gesteu¬ ert von dem elektrischen Anschluss 3 so mit Strom versorgt werden, dass eine gewisse angenehme Vorwärmtemperatur an den Wärmeleitplatten entsteht, die bei eingelegtem Stetho- skopkopf dadurch an die Abhörflächen des Kopfes übertragen wird, dass zwischen den Wärmeleitplatten 2 und den Abhör¬ flächen ein inniger Kontakt besteht. Dies geht aus Fig. 1 hervor.The insertion compartment is delimited at the top and bottom by heat conducting plates 2, which are supplied with power by the electronic components 3 by the electrical connection 3 in such a way that a certain pleasant preheating temperature is created at the heat conducting plates, and when the stethoscopic head is inserted, it starts the listening surfaces of the head is transmitted, that there is an intimate contact between the heat conducting plates 2 and the Abhör¬. This is apparent from Fig. 1.
Die untere Wärmeleitplatte 2 ist nach vorn leicht abge¬ schrägt, um das Einschieben des Kopfes zu erleichtern. Sie ist fest mit einer vom Bodenbereich des Gehäuses 5 gebilde¬ ten Auflagefläche verbunden. Die obere Wärmeleitplatte 2 ist in einer Führung des Gehäuses 5 derart vorgesehen, dass sie gegen den Druck einer Stabfeder in engen räumlichen Grenzen nach oben bzw. nach unten verschoben werden kann, damit Stethoskopköpfe verschiedener Höhe in das Einschub¬ fach hineinpassen und jeweils durch die Stabfeder nach un¬ ten auf die obere Abhörfläche des Kopfes gedrückt werden. Die Stabfeder bildet in entsprechend vorgespanntem Zustand ein nach oben sehr weit geöffnetes V. Die beiden Enden der Stabfeder stecken in passenden Sacklöchern des Gehäuses 5.The lower heat conduction plate 2 is slightly beveled forward to facilitate the insertion of the head. It is firmly connected to a gebilde¬ from the bottom portion of the housing 5 th bearing surface. The upper heat-conducting plate 2 is provided in a guide of the housing 5 such that it can be moved upwards or downwards against the pressure of a bar spring in narrow spatial limits, so that stethoscope heads of different height fit into the slot and in each case through the bar spring pressed down on the upper listening surface of the head. The bar spring forms in a correspondingly prestressed state an upwardly very wide open V. The two ends of the bar spring stuck in matching blind holes of the housing. 5
Den oberen Abschluss des Gehäuses bildet ein Gehäusedeckel 4, der vom oberen Teil des Einschubfaches ausgehend bis zum Bodenbereich des Gehäuses erstreckt ist, wodurch ein bis auf das offene Einschubfach geschlossener Gerätekorpus ent¬ steht.The upper end of the housing forms a housing cover 4, which extends from the upper part of the insertion compartment starting up to the bottom portion of the housing, whereby a device body closed except for the open insertion compartment is ent.
Der Stethoskopkopf 1 ist in Fig. 1 mit einer unteren, grö¬ ßeren Abhörfläche und einer oberen, kleineren Abhörfläche in eingelegtem Zustand und innigem Kontakt mit den Wärme¬ leitplatten gezeigt.The stethoscope head 1 is shown in FIG. 1 with a lower, larger interception surface and an upper, smaller interception surface shown in the inserted state and intimate contact with the heat conducting plates.
In Fig. 2 ist ein erfindungsgemäßes Vorwärmgerät gezeigt, das anstelle von einem Einschubfach zwei Einschubfächer be¬ sitzt. Das linke Einschubfach ist in Fig. 2 mit eingelegtem Stethoskopkopf gezeigt, der zwei Abhörflächen besitzt. Das rechte Einschubfach ist gezeigt mit einem Stethoskopkopf, der nur eine Abhörfläche besitzt. Beide Einschubfächer sind durch eine vertikale Trennwand voneinander getrennt, die als Teil des Gehäuses ausgebildet ist. Im Gehäuse sind Durchbrüche vorhanden, um die Vorwärmplatten des linken und des rechten Einschubfaches ggf. separat mit Strom zu ver¬ sorgen. Die äußere Gehäuseform des zweiten Ausführungsbei- spiels ist im wesentlichen quaderförmig, wobei der obere Bereich des Gehäuses abgerundete Ecken aufweist.FIG. 2 shows a preheating device according to the invention which has two insertion compartments instead of one insertion compartment. The left insertion compartment is shown in Fig. 2 with inserted stethoscope head, which has two listening surfaces. The right slot is shown with a stethoscope head, which has only one listening area.
