Embodiment 1

[0029] Please refer to figure 1 , figure 1 Shown is a schematic structural view of the composite antibacterial catheter 100 . This embodiment provides a composite antibacterial catheter 100 , which mainly includes a tube body 102 , an air bag 104 , an inflation pipeline 106 and a flushing pipeline 108 . The airbag 104 communicates with the inflation pipeline 106 , and the airbag 104 is wound around the outer surface of the tube body 102 . Both the inflation line 106 and the flushing line 108 are located in the tube body 102 . One end of the tube body 102 is provided with a drainage hole 110 , and the drainage hole 110 is adjacent to the air bag 104 . A urinary catheterization cavity 112 is left in the tube body 102 , and the drainage hole 110 communicates with the urinary catheterization cavity 112 . One end of the flushing pipeline 108 close to the drainage hole 110 is provided with a flushing port (not shown in the figure), and the flushing port communicates with the cat...

Embodiment 2

[0034] This embodiment provides a method for arranging multiple second antibacterial layers on the tube body, which mainly includes the following steps:

[0035] Select the basic raw material PVC (polyvinyl chloride).

[0036] The silver nanometer antibacterial agent is inserted into the interlayer of the layered double hydroxide. In order to improve the insertion stability of the silver nano-antibacterial agent, the nano-antibacterial agent is first dispersed into the silica with a network structure, and then the insertion treatment is performed. When dispersing the nano-antibacterial agent into the silica with network structure, disperse the nano-antibacterial agent into the ethanol solution, sonicate for 10 minutes, then add silica and continue ultrasonication for 20 minutes, and ultrasonic nano-dispersion processor is used for ultrasonication.

[0037] After the organic antibacterial agent containing amino active groups is combined with the graphene oxide, the graphene ox...

Embodiment 3

[0043] This embodiment provides a method for arranging multiple second antibacterial layers on the tube body, which mainly includes the following steps:

[0044] The basic raw material is selected, and the basic raw material is a blend of PE (polyethylene) and methyl ethyl silicone rubber.

[0045] The copper-based and zinc-based nano-antibacterial agents are inserted between the layers of the layered double hydroxide. In order to improve the insertion stability of this kind of inorganic nano-antibacterial agent, the nano-antibacterial agent is firstly dispersed into the silica with network structure, and then the insertion treatment is performed. When dispersing the nano-antibacterial agent into the silica with network structure, disperse the nano-antibacterial agent into the ethanol solution, ultrasonic treatment for 30 minutes, then add silicon dioxide and continue ultrasonication for 50 minutes, and ultrasonic nano-dispersion processor is used for ultrasonication.

Abstract

The invention provides a composite antibacterial catheter, which mainly comprises a catheter body, an air bag, an inflation pipeline and a flushing pipeline, wherein due to the arrangement of the flushing pipeline, urinary tract can be flushed while a patient use the catheter so as to reduce the risk of urinary tract infection, the air bag and the catheter body are further provided with a first antibacterial layer and a plurality of second antibacterial layers respectively, the first antibacterial layer is arranged on the outer surface of the air bag, the second antibacterial layers are sequentially arranged at intervals in the thickness direction of the catheter body, the outer surface of the air bag makes direct contact with the body of a patient, and the outer surface of the air bag hascertain antibacterial capacity and is beneficial for further reducing the probability of urinary tract infection of the patient. In the use process of the catheter body, the catheter body releases antibacterial particles layer by layer from the outer layer to the inner layer and the multiple second antibacterial layers, so that the antibacterial time of the catheter body is greatly prolonged, andthe antibacterial capacity is stable so as to reduce the probability of urinary tract infection caused by long-time use of the catheter by a patient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a composite antibacterial urinary catheter. Background technique [0002] Urinary catheters are mainly used for clinical stroke, fractures and retention catheterization of critically ill patients, and are one of the most commonly used medical devices in hospitals. During use, due to various factors, it is often accompanied by catheter-induced urinary tract infection. As the length of stay increases, the rate of urinary catheter infection also increases. The development of medical catheters with antibacterial function is of great significance to reduce the incidence of urinary tract infection and reduce the cost of clinical treatment. At present, the durable antibacterial ability of antibacterial catheters still needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a composite antibacterial urinary catheter, which has a ...
