Catheter capable of preventing urinary tract infection

Abstract

The invention discloses a catheter capable of preventing urinary tract infection, belonging to the technical field of medical instruments. The catheter of the invention comprises a catheter main bodyand a hydrogel layer containing antibiotics. The upper end of the catheter main body comprises a catheter outlet and an inflation valve with a standard joint, and the lower end comprises a catheter inlet and an inflation balloon. The catheter inlet and the catheter outlet are connected by a catheter cavity, and the inflation balloon and the inflation valve are connected by an inflation pipe. The hydrogel layer covers a portion of the catheter body located between the balloon and the catheter outlet. As that hydrogel coat with antibiotics is added on the outside of the conventional catheter tube, the antibacterial of the catheter is effectively realized; at the same time, the hydrogel has a certain sustained-release effect, which delays the release of antibiotics and prolongs the time thatthe catheter can be used. Further, a protrusion is arranged on the outside of the catheter so as to prevent the hydrogel from falling off in the process of use, and the safety of use is ensured.

Description

technical field [0001] The invention relates to a urinary catheter capable of preventing urinary tract infection, belonging to the technical field of medical devices. Background technique [0002] Urinary catheter is the most common medical device in the hospital, which can be used to provide auxiliary treatment and care for patients with specific needs. However, during the use of the catheter, it is often necessary to leave the catheter In the body, urinary tract infection events caused by urinary catheters often occur, which increases difficulties in the treatment process and also brings great misery to patients. [0003] In the prior art, people try many different ways to solve the infection problem caused by the catheter, such as changing the catheter frequently, avoiding the catheter being left in the human body for a long time, but due to the physiological structure of the human body, every time Replacing the urinary catheter will cause physical and psychological tort...

Problems solved by technology

[0002] Urinary catheter is the most common medical device in the hospital, which can be used to provide auxiliary treatment and care for patients with specific needs. However, during the use of the catheter, it is often necessary to leave the catheter In the body, urinary tract infection events caused by urinary catheters often occur, which not only increases the difficulty of the treatment process, but also brings great pain to the patient

[0003] In the prior art, people try many different ways to solve the infection problem caused by the catheter, such as changing the catheter frequently, avoiding the catheter being left in the human body for a long time, but due to the physiological structure of the human body, every time Replacing the urinary catheter will cause physical and psychological torture to the patient. People try to install antibacterial coatings or devices on the outer surface of the urinary catheter to achieve the effect of sterilizing and preventing infection in the body. However, the existence of these coatings , there is often the problem that the catheter is difficult to insert, and if some antibacterial materials leak, it will cause serious harm to the patient

[0004] In the prior art, there are still some methods of spraying antibiotics on the surface of the urinary catheter to avoid infection, but once the catheter enters the human body, the antibiotics will quickly dissipate with the body fluids, and the duration of the antibacterial effect is very short. It plays an antibacterial role, but after a long time, the catheter still needs to be replaced
