Background technology
Medical catheter adopts medical macromolecular materials to process mostly at present; Like silicone rubber, polyurethane, polrvinyl chloride etc.; Wherein these two kinds of macromolecular materials of silicone rubber and polyurethane have excellent biocompatibility; Have not and useful performance such as bodily tissue is bonding, so aspect medical, be widely used.Because the needs of operation or nursing; Often need before art, keep somewhere some medical catheters (like catheter, central venous catheter etc.) or postoperative and keep somewhere some medical catheters (like drainage tube etc.); These conduits are kept somewhere in vivo according to patient's different syndromes needs and were not waited in about 1～30 day, in the indwelling process of medical catheter, very easily cause the infection of keeping somewhere medical catheter periphery tract or wound surface.There are data to show in the urinary catheter in process and kept somewhere infection rate 31% 3 days; 5 days, infection rate 74%; External report catheter accounts for acquired infection and is: the U.S. 40%, and Japan 83%, wherein bacteremia and septicemia take place in 2-4%, and mortality rate is up to 13-30% among the 2-4%.Peripherally inserted central conduit (PICC) was indwelling process 30 days, and infection rate surpasses 10%.
Summary of the invention
This utility model provides a kind of antibacterial superslide medical retention of disposable use conduit that is provided with anti-antibacterial dielectric layer and superslide dielectric layer in order to overcome the shortcoming of above-mentioned technical problem.
The antibacterial superslide medical retention of the disposable use conduit of this utility model; Said conduit comprises the tube wall that is made up of medical macromolecular materials; Its special feature is: the outer surface of said tube wall and or inner surface be provided with the superslide dielectric layer that is used to reduce frictional force between conduit and the tissue, be provided with between said tube wall and the superslide dielectric layer and resist antibacterial dielectric layer.The tube wall that medical macromolecular materials constitute to the human non-toxic side effect, and has good physical property, satisfies medical conditions; Because disposable use medical retention conduit is in the process of using; Need insert and extract in human organ or tissue; The superslide dielectric layer in the tube wall outside can effectively reduce the friction between tube wall and tissue or the organ, when having reduced tissue injury, has also reduced patient's misery; The inboard superslide dielectric layer of tube wall can reduce the detention of conduit to injection, reduces to treat the obstruction that flows out materials such as tissue fluid.Be provided with anti-antibacterial dielectric layer, make it have bacteria resistance function, can reduce the infection that indwelling drainage tube causes to a certain extent, reduce antibiotic consumption, also practiced thrift nursing cost simultaneously.
The antibacterial superslide medical retention of the disposable use conduit of this utility model, said macromolecular material is polrvinyl chloride, polyurethane, silicone rubber or polylactic acid.Polrvinyl chloride, polyurethane, silicone rubber or polylactic acid all can satisfy medical performance, and especially for polyurethane and silicone rubber, its performance is more superior.
The antibacterial superslide medical retention of the disposable use conduit of this utility model, the shape of cross section of said conduit are circle, ellipse, I shape or cross.Be applied in the difference of human body according to conduit, the inlying catheter with different cross section shape is set.
The antibacterial superslide medical retention of the disposable use conduit of this utility model, the material of said anti-antibacterial dielectric layer is nanometer silver, silver oxide, silver ion, chitosan or antibiotic.Nanometer silver, silver oxide, silver ion, chitosan or antibiotic all have good fungistatic effect; During use, can choose the material of anti-antibacterial dielectric layer according to the scope difference that conduit is used, so that make the antibacterial bacteriostatic best results.
The antibacterial superslide medical retention of the disposable use conduit of this utility model, the material of said superslide dielectric layer is liquid paraffin, silicone oil, polyurethane or base polyurethane prepolymer for use as.The superslide dielectric layer that is made up of paraffin, silicone oil, polyurethane or base polyurethane prepolymer for use as all can effectively reduce the frictional force effect between conduit and the organ or tissue and reduce conduit to injection or wait to flow out the detention of tissue fluid.
The antibacterial superslide medical retention of the disposable use conduit of this utility model, said anti-antibacterial dielectric layer and superslide dielectric layer only are provided with at an end of conduit.Because in the process that conduit uses, the most applications downcomer only part of an end extend in tissue or the trachea, therefore can be only anti-antibacterial dielectric layer and superslide dielectric layer be set at an end of conduit.
The beneficial effect of this utility model is: the antibacterial superslide medical retention of the disposable use conduit of this utility model; Through the outer surface of tube wall with or inner surface the superslide dielectric layer is set; Reduced effectively between body and tissue or the organ frictional force, reduced body and treated the obstruction that flows out materials such as tissue fluid, when having reduced, also reduced patient's misery to tissue or tracheal injury; Through anti-antibacterial dielectric layer is set between the inner surface of tube wall or tube wall and superslide dielectric layer, make conduit have the antibacterial bacteriostatic function, reduced the infection that the medical retention conduit causes, reduce antibiotic consumption and practiced thrift nursing cost.
