| 摘要 |
This invention is directed to an improved light source for illuminating examining devices, particularly medical devices such as laryngoscopes. The light source comprises an electrically conducting light bulb holder with a longitudinal passageway therethrough, a light bulb with two depending electrodes snugly positioned in one end of the passageway with a portion of the light generation means extending out of the passageway, a non-conducting insert also having a longitudinal passageway telescopicly interfitting into the other end of the passageway and urging one of the electrodes disposed between the insert and the bulb holder into electrical contact with the latter and an electrically conducting rivet or plug snugly interfitting the exposed longitudinal end of the passage was in the insert and electrically contacting the second electrode disposed within said insert passageway and forming a terminal for the light source. The light source preferably fits into a cavity of a support frame having a metallized, electrically conductive surface. The frame, which holds the batteries and forms the switch to energize the light source position within the cavity, is disposed in the handle of an illuminating or examining device such as a laryngoscope.
