Problems solved by technology

However, for patients who need to keep catheterization for a long time, the incidence of retrograde infection is quite high, resulting in infection of the corresponding parts, such as lower urinary tract infection and even upper urinary tract infection
Invention patent (authorized announcement number CN 200994848Y) discloses a male-specific urinary catheter, which is composed of a urinary catheter, a glans silicone rubber sleeve, and a rubber elastic positioning ring. The structure cannot flush the urethra and bladder to prevent urinary tract infection
None of the catheters currently on the market can flush the urethra to prevent urinary tract infection

Abstract

The invention relates to a urethra washing catheter. A drainage cavity channel is arranged in the catheter, a saccule is arranged on the catheter, the catheter is of a multi-cavity tube structure, the drainage cavity channel is the main cavity channel, and a bladder washing cavity channel and a urethra washing cavity channel are arranged on the tube wall of the drainage cavity channel. A connecting-in port is arranged on each cavity channel on the catheter, and a washing micro hole is formed in the tube wall of the urethra washing cavity channel close to the saccule. The urethra washing catheter is applicable to clinical care, the design method of the multi-cavity tube structure is adopted, the catheter is divided into a plurality of different runners which achieve corresponding functions, are independent and do not affect each other, and therefore retrograde infection and cross infection caused by runner mixing are effectively avoided.

Description

technical field [0001] The invention relates to the field of medical auxiliary devices, in particular to a urethral irrigation catheter. Background technique [0002] Urinary catheter is a commonly used device for clinical treatment of lower urinary tract obstruction, which is convenient to use and easy to operate. However, for patients who need long-term catheterization, the incidence of retrograde infection is quite high, leading to infection of the corresponding parts, such as lower urinary tract infection and even upper urinary tract infection. Invention patent (authorized announcement number CN 200994848Y) discloses a male-specific urinary catheter, which is composed of a urinary catheter, a glans silicone rubber sleeve, and a rubber elastic positioning ring. The structure cannot flush the urethra and bladder to prevent urinary tract infection . At present, the catheters sold on the market cannot flush the urethra to prevent urinary tract infection. Contents of the...
