Probe cover for ear thermometer

Abstract

The present invention discloses a probe cover for an ear thermometer, which comprises: a film cover and a base. The film cover has a cover window able to contact the probe window at the front end of the ear thermometer and a hollow cone able to contact the sidewall of the probe. The width of the cover window is greater than the width of the probe window. Thereby, the present invention can prevent the variation of infrared transmittance caused by the misarrangement and non-uniform thickness of the probe cover film disposed at the front of the probe window.

DETAILED DESCRIPTION OF THE INVENTION

Refer to FIG. 2 and FIG. 3, respectively a perspective view and a sectional view schematically showing the probe cover for an ear thermometer according to the present invention. As shown in the drawings, the probe cover for an ear thermometer of the present invention comprises: a base 20 having a central opening and a film cover 22 having a cover window 221 and a hollow cone 222. The hollow cone 222 extends from the cover window 221 to the central opening of the base 20 and joins the base 20. The base 20 is to be installed to the probe structure 30 of the ear thermometer to encircle the probe structure 30 fixedly. The cover window 221 is to contact the probe window 24 of the probe structure, and the hollow cone 222 is to surround the sidewall of the probe. The base 20 may be made of a more rigid plastic material, and the film cover 22 may be made of an infrared-permeable plastic material.

As shown in FIG. 3, the width of the cover window 221 is at least 0.2 mm greater than the width of the probe window 24. Cooperating with ths base 20, the thickness of the hollow cone 222 is gradually thinned toward the bottom of the probe structure 30. Thus, the thickness b of the film of the hollow cone 222 is smaller than the thickness a of the film of the cover window 221.

Refer to FIG. 4 and FIG. 5 respectively a perspective view and a sectional view schematically showing the film cover sleeves the probe. When the film cover 22 sleeves the probe, the redundant width of the cover window 221 will be pulled to contact the sidewall of the probe. Thus, the film covering the probe window 24 all belongs to the cover window 221, and the film covering the probe window 24 is free from the non-uniformity of the film thickness.

The present invention is characterized in that the width of the cover window is greater than the width of the probe window. Thereby, after the personnel have installed the probe cover over the probe, they can be free from the conventional trouble that they have to check whether the cover window has exactly coincided with the probe window. Thus, the probe cover of the present invention not only can be fast and precisely installed to the probe of an ear thermometer but also can make the film covering the probe window all belong to the cover window. Therefore, the present invention can promote the accuracy of body temperature measurement.

Those described above are only the preferred embodiments to clarify the technical contents and characteristics of the present invention to enable the persons skilled in the art to understand, make and use the present invention. However, it is not intended to limit the scope of the present invention. Any modification and variation according to the spirit of the present invention is to be also included within the scope of the claims of the present invention.
