Txhua tus neeg mob uas tau txais hemodialysis xav tau kev nkag mus rau hemodialysis. Cov neeg mob feem ntau tsis muaj arteriovenous fistula tsim ua ntej, yog li lawv yuav tsum tau tso cov ntshav ib ntus catheter (li no lub npe "hemodialysis catheter") nyob rau hauv cov hlab ntsha sab hauv jugular lossis femoral leeg rau kev lim ntshav. Nws tseem yog ib qho kev nkag mus rau vascular rau kev kho mob xwm txheej ceev, cov neeg mob uas tsis tuaj yeem muaj lub fistula arteriovenous ib ntus vim tsis paub qab hau fistulas lossis lwm yam mob, thiab qee cov neeg mob hemodialysis ntev.
Taw qhia rau hemodialysis catheters
Nyob ntawm lub sijhawm khaws cia sib txawv, hemodialysis catheters tau muab faib ua cov catheters rau lub sijhawm luv luv thiab lub tshuab lim dej mus sij hawm ntev.
Hemodialysis catheters feem ntau yog tsim los ntawm cov hauv qab no:
① Luer connector, uas tuaj yeem txuas nrog hemodialysis tubing, heparin caps, thiab lwm yam;
② Nres clamp, nrog lub ntim ntim ua ntej sau rau ntawm nws;
③ Txuas lub rooj zaum, nrog rau hom, qauv, thiab lwm yam luam tawm ntawm nws;
④ Rotatable suture tis, uas tau yooj yim kho cov kev taw qhia ntawm lub catheter sab qhov;
⑤ Polyurethane cov khoom siv raj lub cev, lub raj lub cev muaj qhov taw qhia ntev, feem ntau 1cm ntu, thiab lub cev lub raj muaj ntau qhov sab (ntau dua 2).
⑥ Lub taub hau. Feem ntau, cov khoom siv tshwj xeeb yog siv, uas yog softer dua lub raj lub cev. Cov hlab ntsha thiab venous qhib ntawm qee cov khoom tsis nyob rau hauv tib txoj kev, tab sis nyob rau hauv ib tug trapezoidal duab kom tsis txhob muaj phab ntsa nqus.
