Description
Kühlvorrichtung für medizinische Zwecke.
Es ist bekannt, dass durch Auflegen von kühlenden Gegenständen Entzündungen, Wunden usw. gaünstig beeinflusst werden können. Ein Nachteil der bekannten Eisbeutel besteht darin, dass sie keine bestimmte, einstellbare und konstante Temperatur auf- weisen.
Die vorliegende Erfindung betrifft nun eine Kühlvorrichtung für medizinische Zwecke, die dadurch gekennzeichnet ist, dass sie ein gegenüber den übrigen Teilen der Kühlvor- riehtung ortsveränderlieh angeordnetes, den Verdampfer enthaltendes Kühlelement auf- weist. Sie kann auch eine Vorrichtung zur Re gulierung der abzugebenden Kältemenge aufweisen.
An Hand einer Zeichnung wird im fol genden eine Ausführungsform der Erfindung beispielsweise besehrieben.
Die einzige Figur ist eine Ansicht des Kühlelementes, teilweise im Schnitt.
Ein Kühltopf 1 besitzt eine mit einem Hebel 2 regulierbare Düsennadel 3. Die Düse 4 befindet sich gegenüber der Kühlplatte 5.
Angeschlossen an den Kühltopf sind die beiden flexible Leitungen 6 und 7, welche zu einer nicht dargestellten, einen Kondensator und einen Kompressor aufweisenden Gruppe führen, welche Gruppe ortsfest, tragbar oder Falirbar sein kann. Mit 8 ist ein IIandgriff hezeiehnet. Zum Betrieb kann irgendein bekanntes Kältemedium benützt werden, z. B. ein Freon. Es gelangt unter Druck aus der I. eitung 6 in die Düse 4, wo es entspannt wird. Die entstehenden Dämpfe werden durch die Leitung 7 wieder abgesaugt. Mit dem He- bel 2 lässt sich die Düsenöffnung und damit auch die durchströmende Kältemittelmenge regulieren.
Das beschriebene Kuhlelement, das den Verdampfer der Kühlvorrichtung enthält, ist somit ortsveränderlich gegenüber den übrigen Teilen (Kompressor mit Kondensator) der Kühlvorrichtung angeordnet.
Das Arbeiten mit der Kühlvorriehtung ist ausserordentlich einfach. Mit dem Hebel 2 wird die gewünschte Temperatur eingestellt, die der Arzt entsprechend der zu heilenden Verletzung bestimmt ; dann wird (natürlich bei eingeschaltetem Kompressor) die Kühlplatte auf die betreffende Körperstelle aufgelegt, wobei es empfehlenswert sein kann, irgendwelche Zwischenlagen anzubringen, z. B. Watte, Gaze oder etwas anderes. Anzahl und Dauer der Behandlungen richten sich nach ärztlichen Anordnungen.
Natürlich liesse sich das Kühlelement auch etwas anders ausbilden.
PATENTANSPRUCH :

UTNTERANSPllÜCHE :
1. Kühlvorrichtung nach Patentanspruch, gekennzeichnet durch eine Vorrichtung zur Regulierung der abzugebenden Kältemenge.
2. Kühlvorrichtung nach Patentanspruch, gekennzeichnet durch ein Kühlplatte zur Abgabe der Kälte.

Cooling device for medical purposes.
It is known that placing cooling objects on the skin can have a positive effect on inflammation, wounds, etc. A disadvantage of the known ice packs is that they do not have a specific, adjustable and constant temperature.
The present invention relates to a cooling device for medical purposes, which is characterized in that it has a cooling element containing the evaporator, which is arranged in a movable manner with respect to the remaining parts of the cooling device. You can also have a device for regulating the amount of cold to be released.
Using a drawing, an embodiment of the invention will be described, for example, in the fol lowing.
The only figure is a view of the cooling element, partly in section.
A cooling pot 1 has a nozzle needle 3 which can be regulated with a lever 2. The nozzle 4 is located opposite the cooling plate 5.
Connected to the cooling pot are the two flexible lines 6 and 7, which lead to a group, not shown, having a condenser and a compressor, which group can be stationary, portable or foldable. With 8 a handle is hezeiehnet. Any known cooling medium can be used for operation, e.g. B. a freon. It passes under pressure from the I. line 6 into the nozzle 4, where it is relaxed. The resulting vapors are sucked off again through line 7. The nozzle opening and thus also the amount of refrigerant flowing through can be regulated with the lever 2.
The described cooling element, which contains the evaporator of the cooling device, is thus arranged to be movable in relation to the other parts (compressor with condenser) of the cooling device.
Working with the cooling device is extremely easy. With the lever 2 the desired temperature is set, which the doctor determines according to the injury to be healed; then (of course with the compressor switched on) the cooling plate is placed on the body part in question, whereby it may be advisable to attach any intermediate layers, e.g. B. cotton wool, gauze or something else. The number and duration of treatments are based on medical orders.
Of course, the cooling element could also be designed a little differently.
PATENT CLAIM:
Cooling device for medical purposes, characterized in that it has a cooling element containing the evaporator, which is arranged to be movable relative to the other parts of the cooling device.
UNDER CONDITIONS:
1. Cooling device according to claim, characterized by a device for regulating the amount of cold to be delivered.
2. Cooling device according to claim, characterized by a cooling plate for releasing the cold.
