Abstract

The invention provides a catheter with an antibacterial coating. The catheter consists of a guide part and a handheld part. According to the catheter with the antibacterial coating, multiple shaping rings are transversely and horizontally arranged on the outer wall of a guide pipe, so that the catheter has good elasticity and rigidity, and the elasticity is gradually reduced but the rigidity is gradually enhanced along with the increase of the length of the guide pipe; and an oval soft head part is arranged at the upper part of the guide pipe, so that the guide pipe is easy to steer, has enough longitudinal thrust, and can easily enter bent and blocked parts. A plurality of flow guide lines are vertically arranged on the inner wall of the guide pipe in the longitudinal direction, and the antibacterial effect can be achieved by attaching antibacterial materials to the flow guide lines while drainage is performed.

Description

【Technical field】 [0001] The present application relates to the technical field of bacteriostasis of urinary catheters, in particular to a urinary catheter with bacteriostatic coating. 【Background technique】 [0002] At present, the most commonly used invasive medical procedures in the medical process are urinary catheterization and indwelling catheterization, and one of the consequences of these two methods is catheter-related urinary tract infection. Infected patients not only aggravate the difficulty of treatment, prolong their recovery time, but also further increase the economic burden of patients. We conducted a retrospective investigation on 457 patients who received indwelling catheterization (not including those with positive midstream urine culture before catheterization). [0003] We found 218 cases of bacteriuria among 457 patients, with an incidence rate of 47.7%. A total of 346 strains of pathogenic bacteria were detected, and an average of 1.6 strains could b...
