| Abstract: |
| The research progress of the materials used in Foley catheter based on natural rubber latex is reviewed.In order to solve the common problems in clinical use of Foley catheter，such as infection，encrustation，blockage and rupture，materials used in response to these problems are summarized.Hydrogels，polytetrafluoroethylene and silicone rubber coatings are effective to alter the properties of Foley catheter surfaces.Silicone rubber is the only material that can replace natural rubber latex for balloon preparation.The design and materials of the Foley catheters still need to be improved.It is suggested to enrich the related standards of Foley catheter，so as to provide reference for the development of new Foley catheters and ensure the safety and effectiveness of the product. |
