AI Technical Summary
Technical Problem
Existing antimicrobial catheters, such as the Frieze catheter, exhibit decreased antibacterial properties after prolonged use, leading to urinary tract infections and other complications. Furthermore, the existing antimicrobial coating is easily peeled off and cannot effectively inhibit biofilm formation.
Method used
The catheter, balloon, and membrane are made of a material combining carbon nanotube polymers and zinc oxide. The drug expulsion pores are formed by laser perforation, which inhibits biofilm formation and maintains antibacterial properties.
Benefits of technology
It maintains its antibacterial properties during prolonged use, reduces the risk of urinary tract infections, extends its lifespan, and reduces patient discomfort.

Abstract
This invention relates to a membrane-type Fritz catheter, comprising: a catheter rod made of a material composed of a carbon nanotube polymer (a combination of carbon nanotubes and zinc oxide (ZnO)) and silicone; a balloon made of a material composed of a carbon nanotube polymer and silicone, engaged with the catheter rod to expand by a first fluid flowing in from the outside; and a membrane made of a material composed of a carbon nanotube polymer and silicone, forming a plurality of pores for draining a second fluid flowing in from the outside, and engaged with the catheter rod.
