Abstract
The utility model discloses a super lubricating vascular intervention therapy catheter. The catheter comprises a vascular intervention therapy catheter for medical use and a hydrogel lubricating membrane. The hydrogel lubricating membrane is firmly coated on outer surfaces of pipe and end of the vascular intervention therapy catheter. When the part combined with the hydrogel lubricating membrane is dip into aseptic water, the hydrogel changes into abnormal lubrication. Compared with the current technology, the super lubricating vascular intervention therapy catheter has the advantages of reasonable design, simple structure, easy manufacturing, convenient using and greatly reducing the pains and sufferings for sufferer, which solves a difficult problem of intervention therapy in clinical medicine with a very good extension and using value.
Description
Technical field:
This utility model relates to a kind of medical apparatus, is specifically related to a kind of bland body inner catheter, interventional therapy conduit in particularly a kind of blood vessel with the little and lubrication property of zest.
Background technology:
Interventional therapy conduit in the blood vessel that uses on the present clinical medicine, generally all be that modification of nylon, polyurethane and PVC material are made, in use the weak point of Cun Zaiing is that the surface and the human vas wall contact friction force of conduit is big, the patient suffering is big in catheter positioning process and the therapeutic process, cause the blood vessel mucosa injury easily, doctor's implementation and operation difficulty.
To the improvement of interventional therapy conduit, generally all rest on the improvement of its internal structure to increase its function.As existing patent ZL97209275.7, disclosed be a kind of medical controlled conductive pipe, and it is an individual hollow pipe, and the conduit front portion is porose, and is built-in with draught line at the sidewall emptying aperture of conduit, by this draught line arbitrarily controlling party to.This conduit can be saved the localized time of intubate, and the success rate height still, but can not alleviate patient's misery.
The utility model content:
It is a kind of little to patient's zest that the purpose of this utility model is to provide, interventional therapy conduit in the super lubricated blood vessel of can alleviate the patient suffering, implement intubate, tube drawing is swift and convenient to operate.
For achieving the above object, take following technical scheme:
Interventional therapy conduit in the super lubricated blood vessel that this utility model provides comprises pedestal, pipeline and head end, it is characterized in that, establishes the hydrogel lubricating film on the outer surface of described pipeline and head end.
Interventional therapy conduit in the above-mentioned super lubricated blood vessel, according to the structure difference, the described head end that has is provided with side opening, and described hydrogel lubricating film is combined in the outer surface that side opening interconnects part.
Interventional therapy conduit in the above-mentioned super lubricated blood vessel is characterized in that, the interventional therapy conduit is pigtail catheter, Naja conduit, hunter's conduit, multi-functional conduit or common hepatic duct in the described blood vessel.
According to technique scheme; owing to combine one deck macromolecule hydrogel lubricating film on the outer surface of the pipeline of interventional therapy conduit intravasation part and head end in the blood vessel; this hydrogel becomes lubricious unusually under chance regimen condition; can significantly reduce the friction of conduit and blood vessel wall; minimizing is to the damage of blood vessel mucosa; thereby can reduce the misery of patient in therapeutic process, shorten treatment time.

Fig. 5 is a head end A part enlarged diagram among Fig. 4.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments in detail this utility model is described in detail:
Referring to Fig. 1-A, 1-B, 1-C, 1-D, 1-E, the interior interventional therapy conduit of blood vessel of difformity and function is shown respectively, but on structure, mainly be divided into pedestal 1, pipeline 2 and head end 3 three parts, in this utility model, main outer surface at pipeline 2 and head end 3 is in conjunction with one deck hydrogel lubricating film 4, referring to Fig. 2 and Fig. 4.
Hydrogel lubricating film 4 envelopes the whole of pipeline 2; For head end 3, see also Fig. 3 and Fig. 5, then its stomidium 31 and side opening 32 must be reserved, promptly at stomidium 31 and side opening 32 bound water gel lubricating film 4 not, and apply hydrogel lubricating film 4 at head end 3 outer surface remainders.
In the processing and fabricating of the present utility model, product for head end 3 band side openings 32, need earlier the material surface of making interventional therapy conduit in the blood vessel to be surpassed lubricated, make the hydrogel lubricating film, carry out the processing and the manufacturing of shape molding then at first attached to material surface.For the conduit of not establishing side opening 32, can directly be lubricated processing with shaped article.The lubricated means can have a variety of, as can be at first at substrate surface in conjunction with one deck coupling agent, combine with water soluble polymer then and form the thin glue of one deck hydrogel, ooze electrolyte at outermost in conjunction with one deck etc. at last, thereby form the hydrogel lubricating film.When super lubrication conduit of the present utility model used, the part that needs to be combined with the hydrogel lubricating film was soaked in sterilized water, and hydrogel will become lubriciously unusually this moment, implement to send the pipe operation will be fool proof smooth.
Can be used for interventional therapy conduit in the blood vessel of the present utility model, can be pigtail catheter, Naja conduit, hunter's conduit, multi-functional conduit or common hepatic duct, but be not limited to listed severally, other similar conduit also can adopt technical conceive of the present utility model easily and makes.
Interventional therapy conduit in the super lubricated blood vessel that this utility model provides, have reasonable in design, simple in structure, be easy to processing, widely applicable, easy to use, alleviate characteristics such as patient suffering greatly, solved a great problem in the clinical medicine in the interventional therapy, had good value for applications.
