-Kraft; Described Kraft is located at the position, buried section of imbedding tissue of extension pipe, and has the fine, soft fur thorn that can be connected together with tissue length in the surface distributed of Kraft;
-to fixed-wing; It is exposed at human body surface section position that described 2 fixed-wings are located at extension pipe, and be arranged symmetrically with respectively; In the middle part of fixed-wing, be useful on human epidermal and implement the fixing pin hole of suture snapping;
At the far-end of described extension pipe, be respectively equipped with the first connection tube and the second connection tube, and the first connection tube is connected perforation with the second inner tube that is located at extension pipe tube cavity is closely sealed, and the second connection tube and the tube cavity of locating to prolong pipe are closely sealed, be connected perforation; Described the first connection tube and the second connection tube, be equipped with respectively first clamp and second clamp for adjust flux; In the terminal of the first connection tube and the second connection tube, be respectively equipped with the gas thread being connected with hemo system artery and vein terminal.
By above given described blood drainage pipe, by wrist position incision surgery, implant is implanted in arteries, again extension pipe is passed to tissue tunnel, be embedded in subcutaneous tissue, by Kraft (cuff) and subcutaneous tissue adhesion, be fixed together, derive the extension pipe of skin outside, by fixed-wing, by suture skin, be fixed together, and then by the first connection tube and the second connection tube, be connected with the artery and vein end terminal interface of hemo system respectively, can start hemo system and implement hemodialysis.Now, implant the blood of the upstream extremity (being proximal part) of endarterial implant, be divided into two-way and enter respectively the first inner tube and implant inner chamber, enter the blood of the first inner tube by the second inner tube and first connection tube of extension pipe, enter hemo system, after hemodialysis again by the second connection tube by extension pipe tube cavity, import the tube cavity of implant, merge together with the blood that directly enters implant tube cavity, be transported to downstream (being distal end), reenter blood circulation of human body.
By above description, can be understood, this utility model is not only rational in infrastructure, safe and reliable, do not change blood direction, do not increase heart burden, and by this utility model is imbedded in body, hemodialysis all to be had an acupuncture treatment at every turn, alleviate patient's misery, thereby realized the purpose of this utility model.
In technique scheme, this utility model also comprises the first chock plug and the second chock plug that is respectively used to block the first connection tube and the second connection tube; Described the first chock plug and the second chock plug, be connected with the gas thread of the second connection tube terminal with the first connection tube respectively, or with cylindrical or the endoporus tight fit connection of described connection tube terminal.The object of this technical scheme is, can avoid occurring when non-hemodialysis that blood of human body leaks and the problem of contaminated blood drainage tube.
In technique scheme, this utility model advocates that the length of described implant is within the scope of 2.5 ~ 3.5cm; Described extension pipe and implant intersect bypass junction, are located at the position apart from implant upstream extremity 2/3 implant length.Why extension pipe is arranged in to implant apart from the position of implant upstream extremity 2/3 implant length, its objective is in order effectively to avoid entering the blood of implant tube cavity, enter extension pipe tube cavity, thereby avoid occurring blood recirculation phenomenon in during hemodialysis.
In technique scheme, this utility model also advocates, described in be located at and implant intraluminal the first inner tube, and described in the place of being located at prolong intraluminal the second inner tube, be all by thermoplastic shaping, and be fixedly connected on respectively the intraluminal of implant and extension pipe.Can certainly adopt spot gluing mode to implement to be fixedly connected with.
Technique scheme is implemented in full, and this utility model is in clinical practice application, and what show is rational in infrastructure, and blood drainage is smooth and easy, and the harmful effect that human body is caused is little, and patient suffering is light etc., and feature is apparent.
