However, its use has been limited to exploratory applications in a small number of cases, and the underlying mechanisms remain largely undefined. To facilitate broader clinical implementation, comprehensive molecular mechanism studies via extensive animal experimentation are essential. Rats, due to their ease of modeling COPD and the availability of comprehensive molecular reagents, serve as an optimal model for such studies. Consequently, the development of electrodes specifically designed for HV-PEF respiratory ablation in SD rats is of significant importance. In this study, we meticulously examined the anatomical structure of rat airways and investigated various equipment parameters, including material composition, rigidity, diameter, electrode ring dimensions, spacing between positive and negative poles, insulation coating for the catheters, welding techniques between the guidewire and electrode ring, and the design of vent holes in the catheter. Based on these considerations, we fabricated PVC ablation electrode catheters with integrated ventilation functionality. Subsequently, we employed finite element simulation to estimate the field strengths that could be applied by these electrodes. The simulation results were then validated in normal rats to assess the electrical safety and efficacy of the electrodes. These findings laid the groundwork for further investigation into the mechanisms of HV-PEF treatment for COPD.","PeriodicalId":52535,"journal":{"name":"中国医疗器械杂志","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142512746","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}

A multi-functional module was designed with a modular approach, and the control of the wheelchair body and each functional module was implemented using an STM32 single-chip microcomputer. A three-dimensional model was established using SolidWorks software. In conjunction with Adams and Ansys simulation software, kinematic and static analyses were conducted on the knee joint rehabilitation institution and its core components. A prototype was constructed to verify the equipment's actual performance.Results: According to the prototype testing, the actual range of motion for the knee joint swing rod is 15.1°~88.9°, the angular speed of the swing rod ranges from -7.9 to 8.1°/s, the angular acceleration of the swing rod varies from -4.2 to 1.6°/s², the thrust range of the electric pushrod is -82.6 to 153.1 N, and the maximum displacement of the load pedal is approximately 1.7 mm, with the leg support exhibiting a maximum deformation of about 1.5 mm.Conclusion: The intelligent knee joint rehabilitation wheelchair meets the designed functions and its actual performance aligns with the design criteria, thus validating the rationality and feasibility of the structural design.","PeriodicalId":52535,"journal":{"name":"Zhongguo yi liao qi xie za zhi = Chinese journal of medical instrumentation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142001348","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}
