Utilizing a modular structure comprising an outer sheath tube, inner sheath tube, and blocking tube, the STET offers increased flexibility in one-lung ventilation (OLV) and airway clearance, thereby reducing airway trauma and improving ventilation efficiency. Its dual-cuff system ensures stable positioning, while its versatile design accommodates diverse patient populations, including pediatric patients and those with difficult airway anatomy. This review explores the structural characteristics, manufacturing processes, clinical advantages, potential limitations, and practical applications of the STET. After multiple rounds of structural optimization, the STET design has successfully advanced into pilot production. Preliminary validation results from small-scale manufacturing and functional testing demonstrate promising structural stability, operational flexibility, and safety performance. The STET represents a significant advancement in airway management, holding substantial potential to improve patient outcomes and transform clinical practice in thoracic surgery and critical care anesthesiology.</p>","PeriodicalId":47140,"journal":{"name":"Medical Devices-Evidence and Research","volume":"18 ","pages":"281-290"},"PeriodicalIF":1.3,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12065468/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144034909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Smart infusion pump interoperability with electronic health records (EHRs) has the potential to reduce intravenous (IV) medication administration errors. Smart Infusion pumps safely deliver IV medications using drug libraries that set standard dosing limits.
