Domestic innovative third-generation urinary catheter unveiled at World Health Organization

"Since the birth of the first generation of urinary Foley catheter in 1860, the problem of clinical urinary leakage has not been solved. The third generation of innovative ureteral catheter with independent intellectual property rights and exclusive invention patents were created based on the anatomical structure of the bladder and the physiological functions of the human body. The dual-channel structural design solves this problem.

On April 7, at the Wuhan Health World Expo, clinical medicine expert Wang Quan introduced the development process and advantages of the new generation of urinary indwelling catheter to the audiences.

Wang Quan introduced that the coude catheter can be called the first generation of urinary catheter and is still in use today. In 1935, Americans invented the second-generation urinary catheter. Although the problem of the first-generation urinary catheter not being able to be left in place was solved, the phenomenon of urine leakage has always troubled doctors and patients.

Urinary leakage after catheter insertion can lead to many adverse clinical consequences. The head nurse of Guanhua, Department of Urology, Peking University First Hospital, who has 20 years of clinical nursing experience and 10 years of experience as a head nurse, often encounters such problems in the ward. She said: "Urine leakage can easily cause incontinence dermatitis in patients, especially For patients who are bedridden and wear indwelling catheters for a long time, urine leakage will increase the risk of pressure injuries. If not taken care of in time, it may cause the patient's skin to rupture and then cause infection. In addition, the patient's negative emotions caused by urine leakage cannot be tolerated. ignore.

How does the third-generation urinary catheter solve the problem of clinical urinary leakage? "We all know that the most effective way to solve the problem of water leakage is to block the incoming water. The researchers found that the second-generation urinary catheter only opened at the top of the urinary catheter. Although the urine above the opening of the urinary catheter in the bladder could be drained smoothly, However, the part of urine accumulated at the lower end of the diversion opening cannot pass through, thus forming residual urine in the bladder, which is the fundamental cause of urine leakage. The third-generation urinary Foley Catheter follows the principle of "without residual urine, there will be no leakage" "Urine" logic, explores the pathophysiology and other mechanisms of human urination and leakage, pioneeringly proposes a dual-channel theory that conforms to the functional structure of the human bladder, and effectively solves the problem of urine leakage through complete diversion," Wang Quan said.
