Urethral catheter capable of preventing related infection of urethral catheter

Abstract

The invention discloses a urethral catheter capable of preventing related infection of the urethral catheter, belongs to the field of medical instruments, and solves the problem that the related infection of the urethral catheter is easily caused by the existing urethral catheter. The urethral catheter comprises a pipe body; the front portion of the pipe body is provided with an end opening or / and a side hole, the cross section of the pipe body is triangular, and the vertex of the triangle is a fillet. The pipe body is designed into the triangular pipe, and the three edges of the triangular pipe have an excellent supporting effect on urethra. Due to the design of the triangular pipe, related infection of the urethral catheter can be automatically prevented; on one hand, the contact area of urethral mucosa and the urethral catheter is minimized, the non-contact area is maximized, stimulation of the catheter to the urethral mucosa and adhesion and aggregation of bacteria on the surface of a carrier are reduced to the maximum extent, and formation of bacterial biofilms and urethral secretions is advantageously reduced; and on the other hand, a gap is formed between the urethra and the catheter body and serves as a drainage space, and the outer wall of the catheter body serves as a drainage track, so that local exudates and secretions can be discharged after the urethra operation.

Description

technical field

[0001] The invention belongs to the field of medical devices, and in particular relates to a catheter for preventing urinary catheter-related infection. Background technique

[0002] Indwelling urinary catheter is a basic technique commonly used in clinical diagnosis and treatment. It is widely used in urinary retention, dysuria, and drainage of urine after surgery. It is one of the commonly used clinical treatment and observation methods. Catheter-associated urinary tract infection is also the most common nosocomial infection. It has been reported abroad that about 35%-40% of hospital-acquired infections are urinary tract infections, and 90% of them are related to urinary catheters. There are also similar reports in China that the proportion of urinary tract infections caused by indwelling catheters in my country's nosocomial infections is 20.8%-31.7%, second only to respiratory tract infections. Catheter-associated urinary tract infection will not only inc...
