INTRAVENOUS CATHETER OF A POLYMER COMPOUND MATERIAL WITH ORIENTED NANOPARTICLES, WITH LOW FRICTION COEFFICIENT AND LOW MICROBIAL ADHERENCE

摘要

The invention relates to an intravenous catheter for administering drugs or fluids to the vascular system of a patient, and in particular relates to peripheral intravenous catheters, central intravenous catheters and other types of catheters that are placed in the vascular system of a patient in order to administer or remove fluids. The catheter is formed by a tube (1) made up of a lumen (14) with a lumen wall (13) made of a polymer matrix reinforced with nanoparticles oriented in specific directions and with a low friction coefficient; the lumen wall (13) is coated with a coating (12) made of a compound of a bactericidal material with a low friction coefficient. The catheter of polymer compound material with oriented nanoparticles, with low friction coefficient and low microbial adherence of the invention has the advantages of: a) reducing the forces of resistance or friction of the catheter against the tissue of the patient when the catheter is inserted; b) having compounds of bactericidal material that reduce the adherence of microorganisms on the surface of the catheter and the growth thereof, thus avoiding the generation of infections in the catheterisation areas; and c) the orientation of the reinforcing particles grants the catheter mechanical properties that provide comfort for the patient during the catheterisation procedure and all the related treatment.
