| Abstract: |
| 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． |
