Abstract
The speculum is particularly intended for the diagnostic examination of the mouth and the upper airways. At the same time, the mirror part (1) should not be misted by moisture. For this, the speculum has an electrical heating element (4) which can be connected (via 6) to an external current source and is built in between the mirror disc (1) and housing (2) of the speculum. In order to prevent said misting, the mirror disc is warmed to the correct temperature by the heating element. <IMAGE>

PATENTANSPRÜCHE
1. Spiegel zur Untersuchung von Körperhöhlen, dadurch gekennzeichnet, dass zwischen dem spiegelnden Teil (1) und dem Spiegelgehäuse (2) zur Erwärmung ein elektrisches Reiz- element (4) mit Anschlüssen (6) zu einer äusseren Stromversorgung eingebaut ist.
2. Spiegel nach Anspruch 1, dadurch gekennzeichnet, dass das Heizelement des Spiegels aus einer elektrischen Leiterplatte besteht.
3. Spiegel nach Anspruch 1, dadurch gekennzeichnet, dass das Heizelement aus einem auf der Vorder- oder Rückseite des spiegelnden Teiles aufgedampften elektrischen Leiter besteht.
4. Spiegel nach Anspruch 1, dadurch gekennzeichnet, dass das Heizelement des Spiegels aus einem eingelegten sogenannten Peltier-Element besteht.
Die vorliegende Erfindung betrifft einen Spiegel zur Untersuchung von Körperhöhlen, insbesondere für diagnostische Betrachtung des Mundes und der oberen Luftwege (Nasen Rachenraum, Kehlkopf).
Wird ein handelsüblicher Spiegel z. B. zur Untersuchung der Mundhöhle benützt, beschlägt er sich sofort durch die Feuchtigkeit der Atemluft. Um das Beschlagen zu vermeiden, wird der Spiegel vor Beginn der Untersuchung an einer getrennten Wärmequelle (z. B. Gasflamme) auf die erforderliche Temperatur vorgewärmt. Die Temperatur wird dann durch Auflegen des Spiegels auf den Handrücken des Untersuchers kontrolliert.
Nachteile der bisherigen Technik: der Spiegel verliert schnell seine Wärme und beschlägt sich, die Sterilität des Spiegels ist nicht gewährleistet wegen der Temperaturkontrolle mit Handrücken, bei länger dauernden Untersuchungen mehrmaliges Erwärmen nötig, dabei Verschleppen von Mundsekret des Patienten auf die Haut des Untersuchers,
Zeitverlust.
das jetzige Verfahren mit einer offenen Feuerquelle ist umständlich und z. B. im Operationssaal wegen Narkosegasen gefährlich.
Mit dieser Erfindung sollen diese Nachteile weitgehend ausgeschaltet werden.
Die Erwärmung des Spiegels auf die gewünschte Temperatur wird dadurch erreicht, dass zwischen dem Spiegelnden Teil und dem Spiegelgehäuse zur Erwärmung ein elektrisches Heizelement mit Anschlüssen zu einer äusseren Stromversorgung eingebaut ist. Der elektrische Anschluss wird vorzugsweise durch den Griff des Spiegels geführt.
Das Heizelement ist vorzugsweise eine separate dünne Lei terpiatte mit einer geeigneten Isolationsschicht gegenüber dem Spiegelgehäuse. Als Leiterplatte kann auch ein sog. Peltier Element eingesetzt werden. Auf der Vorder- oder Rückseite des spiegelnden Teiles kann aber auch ein elektrischer Widerstandsdraht aufgedampft werden.
Mit einer geeigneten äusseren elektronischen Schaltung wird der Strom nach Erreichen der erforderlichen Temperatur konstant gehalten.
Im folgenden wird anhand der beiliegenden Zeichnung ein Ausführungsbeispiel der Erfindung näher beschrieben.
Mit 1 ist eine Spiegelscheibe, mit 2 das Spiegelgehäuse, mit 3 der Spiegelgriff, mit 4 das Heizelement, mit 5 die Isolationsschicht und mit 6 die elektrische Zuleitung bezeichnet.
Der in der Figur dargestellte Spiegel zeigt zwischen dem Spiegelgehäuse 2 und der Spiegelscheibe 1 das Heizelement 4.
Zwischen dem Gehäuse 2 und dem Heizelement 4 befindet sich eine Isolationsschicht 5. Durch den Spiegelgriff 3 führen die elektrischen Anschlüsse 6 zur Stromquelle.
Ein Spiegel dieser Ausführung gewährleistet dem Patienten und dem Untersucher eine sterile und schnelle Untersuchungsweise, er ist bequem in der Handhabung und wird sich nicht beschlagen.

PATENT CLAIMS
1. Mirror for examining body cavities, characterized in that an electrical stimulating element (4) with connections (6) to an external power supply is installed between the reflecting part (1) and the mirror housing (2) for heating.
2. Mirror according to claim 1, characterized in that the heating element of the mirror consists of an electrical circuit board.
3. Mirror according to claim 1, characterized in that the heating element consists of an evaporated on the front or back of the reflecting electrical conductor.
4. Mirror according to claim 1, characterized in that the heating element of the mirror consists of an inserted so-called Peltier element.
The present invention relates to a mirror for examining body cavities, in particular for diagnostic observation of the mouth and the upper airways (nasopharynx, larynx).
If a commercial mirror such. B. used for examining the oral cavity, it immediately steams up through the moisture in the air we breathe. To prevent fogging, the mirror is preheated to the required temperature using a separate heat source (e.g. gas flame) before starting the examination. The temperature is then checked by placing the mirror on the back of the examiner's hand.
Disadvantages of the previous technology: the mirror quickly loses its heat and mists up, the sterility of the mirror is not guaranteed due to the temperature control with the back of the hand, repeated heating is necessary in the case of long-term examinations;
Wasted time.
the current process with an open fire source is cumbersome and z. B. dangerous in the operating room because of anesthetic gases.
These disadvantages are to be largely eliminated with this invention.
The heating of the mirror to the desired temperature is achieved in that an electrical heating element with connections to an external power supply is installed between the reflecting part and the mirror housing for heating. The electrical connection is preferably made through the handle of the mirror.
The heating element is preferably a separate thin Lei terpiatte with a suitable insulation layer against the mirror housing. A so-called Peltier element can also be used as the circuit board. An electrical resistance wire can also be vapor-deposited on the front or back of the reflecting part.
With a suitable external electronic circuit, the current is kept constant after the required temperature has been reached.
In the following an embodiment of the invention will be described with reference to the accompanying drawings.
1 is a mirror disk, 2 is the mirror housing, 3 is the mirror handle, 4 is the heating element, 5 is the insulation layer, and 6 is the electrical lead.
The mirror shown in the figure shows the heating element 4 between the mirror housing 2 and the mirror disk 1.
There is an insulation layer 5 between the housing 2 and the heating element 4. The electrical connections 6 lead to the power source through the mirror handle 3.
A mirror of this design guarantees the patient and the examiner a sterile and quick examination, it is easy to use and will not fog up.
