Abstract

一种防凝露间接式喉镜,它是由反光镜,半导体制冷器、壳体、手柄及导线组成,半导体制冷器安装在反光镜与壳体之间处,其热端与反光镜接触,冷端与壳体接触,导线沿手柄管径孔接出,当接上电源的半导体制冷器的热端产生热量对反光镜加热,加热后的反光镜伸入人体咽喉部不会产生凝露保持清晰,半导体制冷器的冷端与壳体接触使壳体保持较低温度,伸入人体咽喉部不会引起灼热不适感。

Description

防凝露间接式喉镜
本实用新型涉及一种临床医学检查咽喉疾病用的间接式喉镜,特别是防凝露间接式喉镜。
临床医学现在使用的间接式喉镜是由反光镜,金属壳体和手柄组成,使用时手持手柄将反光镜部份伸入患者咽喉部,通过反光镜观察咽喉部状态是否有变异,但是由于反光镜玻璃的温度常常低于人体咽喉部温度,当反光镜伸入人体咽喉部即会迅速出现凝露,导致反光镜模糊不清,影响了观察效果。临床医生只有将反光镜使用酒精灯的火焰加温,使之高于人体咽部腔内的温度,再伸入咽喉腔内检查,这样虽然改善了镜面凝露现象,但是有时加温过高伸入人体咽喉部常常引起咽部接触不适,使用也不方便。
本实用新型的目的是要提供一种伸入人体咽喉部不会产生凝露能保持清晰镜面的间接式喉镜。
本实用新型是这样实现的:在反光镜的背面与固定反光镜的壳体之间安装一只半导体制冷器。半导体制冷器通电工作时一端放热另一端产生冷量,安装时使半导体制冷器的热端与反光镜接触,通电之后反光镜被加热,加热了的反光镜伸入人体咽喉部即不会产生凝露现象,半导体制冷器的冷端与固定反光镜的壳体接触,使其壳体得到冷量不会出现过热现象保持了较低的温度,当伸入人体咽喉部接触到人体组织也不会产生灼热不适感。
下面结合附图对本实用新型作详细说明:
图1是本实用新型结构示意图;
参照附图:反光镜(1)由壳体(3)固定,反光镜(1)与壳体(3)之间处安装半导体制冷器(2)、半导体制冷器(2)的热端与反光镜(1)接触,半导体制冷器(2)的冷端与壳体(3)接触,半导体制冷器(2)的导线(5)经壳体(3)沿手柄(4)管径孔接出,只要接上电源半导体制冷器(2)热端即可对反光镜加热。
