Das herkömmliche, ovale Fieberthermometer in seiner Beschaffenheit ist unbestritten das hygienischste, preiswerteste und vor allen Dingen in seiner Präzision nach wie vor wirtschaftlichste Instrument zur Messung der Körpertemperatur. The conventional clinical thermometer oval in its nature, is undoubtedly the most hygienic, inexpensive and above all in its precision still economical instrument for measuring the body temperature.
Es hat sich aber in der Handhabung und Praxis ergeben, daß die Ablesbarkeit Schwierigkeiten bereitet, insofern, daß die Möglichkeit des Ablesens durch die Form des Kapillarröhrchens nur unter einem Einfallswinkel von ca. 5 Grad gegeben ist.However, it has emerged in handling and practice that that the readability is difficult to the extent that the possibility of reading through the shape of the Capillary tube only at an angle of incidence of approx. 5 degrees is given.
Es wird ein ovales Fieberthermemeter vorgeschlagen, bei welchem auf das Kapillarröhrchen ein Zusatzstab aufgesetzt wird, welcher aus einem Material besteht, welches glasklar ist und einen möglichst ähnlichen Brechungsindex wie das Kapillarröhrchen besitzt (vorzugsweise Glas oder Acrylharz).An oval clinical thermometer is proposed at which an additional rod is placed on the capillary tube, which consists of a material that is crystal clear and has a refractive index as similar as possible to the capillary tube (preferably glass or acrylic resin).
Dieser Zusatzstab kann mittels eines Speziolklebers symmetrisch auf den asphärischen Teil des Kapillarröhrchens aufgeklebt werden und zwar über die ganze Länge des Teilungsbereichs.This additional rod may be glued by means of a Speziolklebers symmetrically on the aspherical part of the capillary tube and that over the entire length of the pitch range.
Der Kleber sollte vorzugsweise glasklar sein und einen ähnlichen Brechungsindex wie das Kapillarröhrchen und der Zusc+.zstab besitzen.The glue should preferably be crystal clear and one have a refractive index similar to that of the capillary tube and the Zusc + .zstab.
