The utility model discloses an anti-blurring device for bronchoscope lens, which comprises a protective cover, a heating sleeve and an elastic ring. The protective cover is a hollow cylinder made of transparent polymer material with a height of 1_2 mm. The upper end is provided with a lens hole matching the bronchoscope lens end, a biopsy channel and a functional channel, and the lower end of the protective cover is connected. The upper end of the heating sleeve is provided with a limit table, the middle layer of the heating sleeve is provided with an electric heating film, and the inner layer is a heat conducting layer. The electric heating film at the lower end of the heating sleeve is provided with an electric terminal, and the lower end of the heating sleeve is fixedly connected with the elastic ring. The anti-blurring device of the bronchoscope lens of the utility model can cover the front end of the bronchoscope on the heating sleeve by pre-heating the electric heating film before use, and the lens end reaches the limit table without exceeding the protective cover, thus effectively avoiding the blurring caused by the contamination of the bronchoscope lens and obtaining a good field of vision.
【技术实现步骤摘要】
一种支气管镜镜头防模糊装置
本技术涉及医疗设备
,具体涉及一种支气管镜镜头防模糊装置。
技术介绍
众所周知,在支气管镜等内镜手术过程中,支气管镜的镜头相当于手术者的眼睛,能对人体支气管进行全面的观测。但是,在操作过程中,支气管镜镜头可能会被气道内的分泌物,如痰、血迹等沾染,导致支气管镜镜头模糊,不能获得较好的操作视野。临床工作时,为避免这类情形,使镜头始终保持在气道中央,如果偏向气道壁,镜头可能被气道壁上的分泌物沾染模糊;在抽吸灌洗液时不可离管口太近。离管口远一点作吸引同样可以有效吸引灌洗液或血液,同时不会使血液或灌洗液污染镜头,如果出现镜头模糊,可以使镜头贴壁,轻轻摩擦气道壁,可以使镜头模糊消失;冲入少量盐水,可以使镜头模糊消失;或者是拔出支气管镜镜头进行清洁。但是均存在效果不理想或者操作不便等问题。
技术实现思路
本技术的目的在于克服现有技术中存在的上述问题,提供一种支气管镜镜头防模糊装置,使用前通过对电加热膜预加热,将支气管镜先端部套在可加热套上,镜头端到达限位台而不超过防护罩,在使用时能有效避免支气管镜镜头受沾染导致模糊,获得良好的视野。为实现上述技术目的, ...
