摘　　要：天然胶乳气囊导尿管通过拼装和凝固剂与硫化胶乳的多次交替浸渍和干燥工艺制备而成。通过调整凝固剂和硫化胶乳的组分或固形物质量分数,分别形成首层湿凝胶、形成充液腔和注药腔的胶膜层及装球囊后覆盖在球囊上的胶膜层等。分析每次浸渍凝固剂和硫化胶乳的工艺特点,以适应不同规格和结构的天然胶乳气囊导尿管的需求。Natural latex aerocyst catheter was made by assembling,multiple impregnation and drying of the coagulant agent and vulcanized latex.By adjusting the components or solid mass fraction of the coagulant agent and vulcanized latex,different layers were formed,including the first layer of wet gel,the layer of filling cavity and injection cavity,and the layer covering on the balloon after assembling.The process was designed to meet the various needs of natural rubber latex balloon catheters of different specifications and structures,and the process characteristics in each impregnation step were summarized.
