Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of hemodialysis catheter that chronic renal insufficiency is needed the long term maintenance hemodialysis.
Background technology
The patient of chronic renal insufficiency (Uremic) needs the long-term hemodialysis that relies on to sustain life, and vascular access is patient's " life line ".Generally speaking, adopt puncture artery and vein internal fistula to set up hemodialysis (hereinafter to be referred as hemodialysis) peripheral passage, it is called as classical hemodialysis path.The internal fistula because each hemodialysis all need puncture, blood vessel sustains damage easily, and the complication such as internal fistula thromboembolism occur easily, causes internal fistula can't continue to use; Perhaps because patient self PeV condition is poor, set up artery and vein internal fistula difficulty; Only a few adopts the artery and vein blood vessel that directly punctures to set up the hemodialysis path, and the generation of its false aneurysm often brings serious consequence.Clinically, set up the hemodialysis path for basically adopt the provisional hemodialysis conduit of cannula of deep vein than the patient who carries out hemodialysis in short-term, because this Keeping time of catheter is short and be not easy to nursing, therefore is not suitable with those without the artery and vein internal fistula and needs the patient of long term maintenance hemodialysis.This class patient that appears as that chronic hemodialysis is analysed conduit has brought great Gospel.At present, mainly contain Quinton on the domestic market, about Covidien(Tal Palindrome30mm, the clinician can't choose appropriate catheter length according to factors such as patient's height, the bodily forms and carry out Operation.
Since unmarked on the catheter surface, cause the doctor not know that in use this conduit inserts endovascular length, need by method for distinguishing, judge that such as (image documentation equipment) conduit inserts endovascular length.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art
,This utility model provides a kind of and can choose suitable catheter length according to factors such as patient's height, the bodily forms and carry out Operation,, reduce the blindness of operation, the adjustable long-term two-chamber hemodialysis catheter of greatly increasing work efficiency.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of adjustable long-term two-chamber hemodialysis catheter, comprise supervisor, supervisor is for having biocompatibility and roentgenopaque medical silica-gel body, supervisor inside is provided with two independently tube chambers, the end of two tube chambers is respectively equipped with ostium arteriosum and ostium venosum cordis, ostium venosum cordis is positioned at supervisor's end, between ostium arteriosum and the ostium venosum cordis at a distance of 60mm-90mm; It is the polyester circular A of 5mm-15mm that supervisor's outer wall is socketed with for fixing width apart from the position of ostium arteriosum 40mm-60mm, the front end of polyester circular A is socketed with the model polyester circular B identical with polyester circular A at a distance of the position of 30mm, the position of polyester circular B front end 20mm-30mm is provided with fixed-wing, article two, extension tube links to each other with supervisor by Triangulum, be carved with the scale value of 10mm length mark to supervisor's end from polyester circular A, the hole string is useful on the switch folder of open and close extension tube function on the extension tube, and two extension tube afterbodys are connected with female Luer.
Described Triangulum is inner bifurcation structure, and two chambeies of being responsible for are connected with two extension tubes, and described extension tube is flexible straight tube.
Described fixed-wing two ends are provided with when sewing up the through hole that conduit is fixed on the skin.
Described ostium venosum cordis is circular cross section, and its external diameter is 11.5Fr-12.5Fr, and the ostium arteriosum external diameter is 13.5Fr-14.5Fr.
The beneficial effects of the utility model are: 1, the doctor can be according to factors such as patient's height, builds, the most advanced and sophisticated endovascular body surface position of inserting of measuring guide, duct of Arantius can be wiped out 30mm-60mm, implant to choose suitable length, the distance of ostium arteriosum and ostium venosum cordis is no less than 30mm in principle, in order to avoid increase the recirculation of blood in the hemodialysis, affect the hemodialysis curative effect; 2, because supervisor is marked with scale value, the doctor can readily appreciate that in use conduit inserts endovascular length, has improved widely work efficiency; 3, the distance of ostium arteriosum and ostium venosum cordis is 60mm-90mm, has reduced greatly the recirculation of blood in the hemodialysis, has improved dialytic efficiency; 4, because supervisor cross section medium-sized vein mouth is circular cross section, can increase to greatest extent blood flow.
