AVF Needle Specification Classification, Hom Khoom Thiab Kev Ua Lag Luam Daim Ntawv Thov Scenario Segmentation

Lub ntiaj teb ArteriovenousFistula koobkev ua lag luam nthuav tawm cov qauv khoom sib txawv nrog cov kev qhia meej meej thiab segmented daim ntawv thov scenarios. Raws li kev xav tau ntawm cov ntshav txaus, cov neeg mob vascular mob thiab cov xwm txheej kho mob, AVF koob tau muab faib ua ntau yam kev ntsuas thiab cov qauv, suav nrog cov chaw ua haujlwm lim ntshav, lub tsev kho mob nephrology department thiab kev lag luam hauv tsev. Cov khoom tsim qauv sib txawv paub meej qhov sib txuam nrog cov xwm txheej kho mob sib txawv, ua tau raws li tus kheej xav tau kev kho mob ntawm cov neeg mob sib txawv, thiab txhawb nqa tag nrho cov kev pab cuam ntawm AVF koob lag luam hauv hemodialysis teb.

Nyob rau hauv cov nqe lus ntawm kev faib cov ntsiab lus tseem ceeb, AVF koob nyob rau hauv lub ntiaj teb no kev ua lag luam feem ntau yog muab faib mus rau hauv 15G, 16G, 17G thiab lwm yam mainstream gauge qauv, tsim ib tug gradient khoom system hloov mus rau txawv cov ntshav txaus npaum li cas thiab vascular tej yam kev mob . 15G loj-gauge AVF koob muaj loj puab txoj kab uas hla thiab ruaj khov rau cov neeg laus cov ntshav txaus{5} fistula cov hlab ntsha thiab cov hlab ntsha zoo, thiab tau siv dav hauv cov neeg laus hemodialysis scenarios, nrog rau kev lag luam loj tshaj plaws daim ntawv thov sib koom. 16G nruab nrab- ntsuas cov khoom sib npaug ntawm cov ntshav khiav efficiency thiab puncture kev nyab xeeb, nrog rau cov koob lub cev tuab, me me vascular puas, dav adaptability, haum rau feem ntau cov neeg laus thiab nruab nrab- cov neeg mob cov khoom lag luam.

17G me me - ntsuas AVF koob feem ntau yog taw qhia rau cov neeg mob tshwj xeeb uas muaj cov hlab ntsha nyias, cov hlab ntsha tsis yooj yim thiab cov fistula tsis zoo, xws li cov neeg laus, cov neeg mob me thiab cov neeg mob uas muaj hnub nyoog ntev - lim ntshav- ntxias vascular atrophy. Lub cev koob zoo txo ​​qhov kev raug mob ntawm cov hlab ntsha thiab cov hlab ntsha, ua kom tsis txhob muaj vascular rupture, hematoma thiab lwm yam teeb meem, thiab txhim kho kev nyab xeeb ntawm kev kho mob tshwj xeeb ntawm tus neeg mob. Cov kev ntsuas sib txawv ua rau cov neeg ua haujlwm kho mob xaiv cov khoom lag luam raws li qhov tseeb vascular mob ntawm cov neeg mob, paub txog kev kho tus kheej, thiab txhim kho kev kho mob ntawm cov khoom zoo heev.

Nyob rau hauv cov nqe lus ntawm cov yam ntxwv hom, AVF koob tau muab faib mus rau hauv taag hom thiab rotary hom, nrog txawv kev ua lag luam positioning. Tsau AVF koob muaj qhov ruaj khov tag nrho cov qauv, kho lub cev lub kaum ntse ntse, ruaj khov ruaj khov thaum lub sij hawm lim ntshav, tsis yooj yim rau hloov thiab poob, haum rau cov neeg mob uas muaj kev kho mob ruaj khov thiab cov xwm txheej zoo li qub, thiab muaj cov nqi zoo tshaj plaws thiab kev lag luam thoob ntiaj teb. Rotary AVF koob txais kev hloov pauv hloov qauv tsim, uas tuaj yeem hloov kho rau lub cev me ntsis ntawm cov neeg mob thaum lub sijhawm ntev - lim ntshav, txo cov hlab ntsha thiab fistula siab, txo qhov kev pheej hmoo ntawm vascular raug mob thiab rab koob hloov chaw, thiab tsim nyog rau cov neeg mob nquag thiab ntev - lub sij hawm dialysis kev kho mob rau cov khoom lag luam zoo.

Nyob rau hauv cov nqe lus ntawm kev ua lag luam daim ntawv thov scenario segmentation, kev dialysis chaw zov me nyuam yog qhov loj tshaj plaws downstream lag luam ntawm AVF koob, accounting rau ntau tshaj 70% ntawm lub lag luam xav tau. Cov chaw kho mob tshwj xeeb muaj cov neeg mob loj txaus, cov txheej txheem kho mob thiab siab - siv zaus thov, uas yog lub lag luam tseem ceeb txhawb kev tsim khoom loj thiab muag ntawm AVF koob. Lub tsev kho mob nephrology departments yog qhov thib ob loj daim ntawv thov scenario, ua qhov kev kuaj mob, kev kho mob thiab tsis tu ncua dialysis ntawm cov neeg mob tseem ceeb thiab tshiab kuaj mob, nrog ruaj khov incremental thov. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho ntawm tsev hemodialysis thev naus laus zis, qhov xwm txheej ntawm kev lim ntshav hauv tsev tau dhau los ua qhov kev loj hlob tshiab ntawm kev ua lag luam. Portable thiab yooj yim-rau- ua haujlwm AVF koob cov khoom tau maj mam nrov hauv khw kho mob hauv tsev, nqa qhov chaw ua lag luam tshiab.

Ntau yam kev qhia tshwj xeeb thiab cov khoom lag luam segmented pab AVF koob kom hloov mus rau qhov kev txhim kho zoo ntawm kev kho mob hemodialysis niaj hnub. Qhov sib txuam ntawm cov khoom thiab cov xwm txheej txhawb nqa cov txheej txheem thiab nrov npe ntawm AVF nkag mus siv thev naus laus zis, thiab tsis tu ncua tso tawm kev lag luam muaj peev xwm ntawm segmented lem.
