Above-mentioned dual firmness superslide J-type conduit, the diameter of catheter body both ends cyclic structure are 5mm ~ 30mm, tip
Length 3mm ~ 10mm of straight section.
Above-mentioned dual firmness superslide J-type conduit, the hard tube segment length of the catheter body are 5cm ~ 20cm, catheter body
Hose segment length is 5cm ~ 20cm.
Above-mentioned dual firmness superslide J-type conduit, the hardness of the hard tube section are 5 ~ 30D bigger than the hardness of flexible tube section.
The color of above-mentioned dual firmness superslide J-type conduit, the hard tube section and flexible tube section is different.
The utility model has the beneficial effects that:
1, the catheter body of the utility model has dual firmness, and catheter body front end is hard tube section, and hard tube section is placed in kidney
In dirty, catheter body rear end is flexible tube section, and flexible tube section is placed in bladder, and such design can reduce rear end flexible tube section cyclic structure
Friction between bladder mucosa, to greatly reduce the generation of bladder irritation and hematuria complication.
2, the utility model coats antibacterial hydrophilic coating in catheter body, which shows superslide after encountering water
Can, superslide performance makes J-type conduit be easy that the pain and secondary injury of patient can be reduced by ureter.
3, in use, the design of tip straight section, so that J-type conduit has good insertion, it will not be because of conduit
Ontology both ends cyclic structure stress is stuck on seal wire.
Detailed description of the invention
Fig. 1 is the positive structure schematic of the utility model.
Fig. 2 is the perspective view of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, a kind of dual firmness superslide J-type conduit, including catheter body, the catheter body front and back two
End is two opposite direction and curved cyclic structures 5 inwardly each other, shaped like pigtail.The tip of two cyclic structures 5 is all provided with
There is tip straight section 4, tip straight section 4 and corresponding cyclic structure 5 are tangent, if uniformly opening up along its length in the catheter body
Dry conduction hole 6, in order to which the ureter between kidney and bladder passes through 6 drainage of urine of conduction hole.The design of tip straight section 4, makes
Obtaining J-type conduit has good insertion, will not be stuck on seal wire because of 5 stress of catheter body both ends cyclic structure.
The catheter body front end is hard tube section 1, and hard tube section 1 is placed in kidney, and catheter body rear end is flexible tube section 3, soft
Pipeline section 3 is placed in bladder, is changeover portion 2 between hard tube section 1 and flexible tube section 3.Catheter body front end is hard tube section 1, and hard tube section 1 is set
