| Zusammenfassung: | The utility model discloses a light screening device for observation when a fiber gastroscope is used for examination, which is composed of three parts, i.e., a rubber ring connected with a glass observation lens of a gastroscope, a spiral elastic rubber connected with the rubber ring and a rubber frame contacting an eye. When a fiber gastroscope is used for examination, the utility model can be used for screening a glass observation lens of the gastroscope from reflection generated by stronger light in the environment, therefore the observation effect on a gastroscope operator is improved and the visual fatigue is eased. The utility model has the advantages of simple structure, convenient operation, high safety, reliability, etc. |
