Testing is an important means of performance evaluation and quality control for intelligent medical devices. Compared with traditional medical devices, the testing methods and technologies of intelligent medical devices are still immature, and need active research to promote the progress in this area. Intelligent medical devices are classified according to their characteristics as artificial intelligence medical devices in the form of software and medical robots based on a general discussion of their development. The medical-device Internet of Things (IoT) system has also been included due to its close relation to the construction of smart hospitals. For each type of intelligent medical device, testing indexes and testing plans are discussed. It is suggested that specific test rules should be further developed for various specific devices. Besides, the evaluation method of complex intelligent systems should be introduced and real-world data should be used for evaluation. This paper aims to accelerate the development of intelligent medical device testing, laying the foundation for quality control and performance evaluation of intelligent medical devices.","PeriodicalId":52535,"journal":{"name":"中国医疗器械杂志","volume":"48 6","pages":"699-705"},"PeriodicalIF":0.0,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142787667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By selecting an appropriate initial retrofocus structure, the optimized modulation transfer function (MTF) curve of the zoom objective lens approaches the diffraction limit. Additionally, the tip and operation parts of the system incorporate modular gas-tight sealing and multiple layers of protective structure. The design employs efficient sealing materials and precise packaging techniques to ensure the system's sealing performance. The experimental results indicate that, under conventional imaging, the resolution is equivalent to 39.37 μm in object space, and the field of view angle is larger than 140 degrees. At magnified imaging, the resolution is equivalent to 2.78 μm in object space, and the observed actual field of view is greater than 800 μm×700 μm. When used with a 26-inch display monitor, the high-magnification electronic endoscope can achieve 500× optical magnification, allowing for the observation of features at the cellular level. Currently, this product has successfully achieved mass production and has undergone multiple animal trials, demonstrating its wide range of potential applications and significant clinical value.","PeriodicalId":52535,"journal":{"name":"中国医疗器械杂志","volume":"48 6","pages":"658-663"},"PeriodicalIF":0.0,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142787696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
