HYDROPHOBIC TEXTURISED FOLEY CATHETER WITH LOW MICROBIAL ADHESION

摘要

The invention relates to medical equipment for treatment, specifically medical equipment for extracting and draining fluids contained in the bladder of a patient. The Foley catheter according to the invention comprises tubing, with at least two lumens, made of a biocompatible polymer material with a length of between 100 and 400 mm and outer diameters of between 1 and 15 mm. The surface of the tubing has a high-relief texture with a maximum height of 30 micrometers and patterns designed to generate the property of hydrophobicity and to reduce the adhesion of bacteria to said surface. A collecting funnel with at least two channels, made from medical-grade polymer material, is fixed to the distal end of the tip of the tubing, while the tip of the tubing is closed in such a way that it forms a rounded tip. A flexible inflatable balloon is arranged upstream of the tip, for the anchoring of the catheter.

主权项

1. A Foley type catheter manufactured from biocompatible polymeric material characterized by the tube having a texturized embossed surface to provide it with hydrophobicity and prevent the first phase of an infection, which consists of fixing the microbe to the surface.
