Thaum tham txog " koob tshuaj lim ntshav vs koob tsis tu ncua", nws yog ib qho tseem ceeb kom nkag siab tias ob hom yog categorized li "khoom siv kho mob", tab sis lawv ua haujlwm sib txawv heev. Lub koob txhaj tshuaj ib txwm siv rau cov tshuaj noj, nqa ntshav, thiab txhaj tshuaj, thaum "kho kom huv" yog tsim tshwj xeeb rau kev nkag mus rau hemodialysis los ntawm arteriovenous (AV) fistula lossis graft. Rau cov neeg ua haujlwm kho mob, cov chaw muag khoom, thiab cov neeg yuav khoom hauv lub ntiaj teb "khoom noj khoom haus" kev ua lag luam muaj peev xwm ua kom paub tseeb tias cov neeg mob muaj kev nyab xeeb.
Dab tsi yog ib rab koob tsis tu ncua?
Ib txwmkoob txhaj tshuajyog tsim los rau cov txheej txheem kho mob xws li:
Kev txhaj tshuaj subcutaneous lossis intramuscular
Kev kuaj ntshav lossis IV tso
Kev tswj hwm tshuaj
Kev txhaj tshuaj
Cov koob tsis tu ncua tuaj nyob rau hauv ntau qhov ntau thiab tsawg los ntawm 18G txog 30G. Qhov tsawg dua qhov ntsuas tus naj npawb, qhov loj ntawm txoj kab uas hla. Rau kev txhaj tshuaj niaj hnub, 23G-27G feem ntau yog tsim los txo qhov tsis xis nyob thaum tso cov kua dej txaus.
Txawm li cas los xij, cov koob tshuaj no "tsis haum rau hemodialysis", vim tias lawv cov lumen yog nqaim dhau thiab qhov ntws tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev kho ntshav kom huv.
Dab tsi yog Dialysis Needle?
A koob dialysis, feem ntau hu ua "AV fistula koob", yog tsim tshwj xeeb rau kev kho mob "hemodialysis", nws tau muab tso rau hauv ib qho arteriovenous fistula kom tso ntshav sai sai ntawm tus neeg mob thiab lub tshuab lim ntshav. Tsis zoo li cov koob li niaj zaus, nws nta:
Qhov ntsuas loj dua rau cov ntshav siab
Ib tug tis tsim rau kev ruaj ntseg fixation
Rov qab-qhov muag los yog pem hauv ntej-qhov muag qhov muag kom smoother ntshav txav
Mos tubing txuas nrog lub tshuab lim dej
Xim-coded qhov ntau thiab tsawg kom paub qhov chaw kho mob yooj yim
Kev lim ntshav yuav tsum tau ua cov ntshav ntau - txog 300-500 mL / min. Yog li ntawd, tsuas yog high-flow dialysis koob tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Dialysis Needle vs Regular Needle: Qhov Sib Txawv Tseem Ceeb
| Feature | Dialysis koob | Koob tsis tu ncua |
| Lub hom phiaj | Kev nkag mus rau hemodialysis | Kev txhaj tshuaj, kev siv IV, tshuaj |
| Ntsuas | 14G-17G (ntau: 15G AV fistula koob) | 18G-30G nyob ntawm kev siv |
| Tus nqi ntws | Ntshav siab (300-500 mL / min) | Tsawg mus rau nruab nrab ntws |
| Tube kev twb kev txuas | Nruab nrog tubing thiab tis | Feem ntau tsis muaj tis lossis tubing |
| Tus neeg mob siv zaus | Rov ua dua rau cov neeg mob ntev | Kev siv qee zaus lossis ib txheej txheem |
| Nthuav qhov chaw | AV fistula los yog graft | Cov leeg, leeg, cov ntaub so ntswg subcutaneous |
Los ntawm qhov kev sib piv no, nws pom tseeb tias koob tshuaj lim ntshav vs koob tsis tu ncua tsis yog qhov loj me xwb - nws yog qhov sib txawv hauv engineering, daim ntawv thov, qauv, thiab kev nyab xeeb.
Dialysis Needle Size Overview
Dialysis koob loj yog qhov tseem ceeb rau cov kws kho mob thiab cov kws kho mob tshwj xeeb. Qhov ntsuas ncaj qha cuam tshuam tus nqi ntws thiab tus neeg mob kev nplij siab. Qhov ntau thiab tsawg siv feem ntau suav nrog:
14G - Txoj kab uas hla loj tshaj plaws, tus nqi ntws siab tshaj plaws
15G AV fistula koob - Feem ntau nrov sib npaug ntawm ntws thiab kev nplij siab
16G - Haum rau cov neeg mob hemodialysis ruaj khov
17G - Rau cov neeg uas muaj fistula tsis yooj yim los yog ua siab ntev
Xim coding feem ntau yog tus qauv rau kev qhia yooj yim-15G nquag tshwm ntsuab, 16G ntshav, 17G liab. Qhov no yuav pab cov neeg ua haujlwm kho mob kom paub meej tias qhov loj npaum li cas thaum kho.
Dialysis Needle Size Comparison Chart
| Ntsuas | Sab nraud | Flow Ceev | Qhov zoo tshaj plaws siv Case |
| 14g ua | Loj tshaj plaws | Siab heev | High-efficiency dialysis, zoo vascular mob |
| 15G (feem ntau siv) | me ntsis me ntsis | Siab | Kev kho mob rau tus neeg laus dialysis Standard |
| 16g ua | Nruab nrab | Nruab nrab-siab | Cov neeg mob ruaj khov, tswj kev nkag mus |
| 17g ua | Qhov tsawg tshaj plaws dialysis koob | Nruab nrab | Cov neeg mob uas muaj cov hlab ntsha tawg yooj yim lossis ua rau siab ntev |
Hauv kev tshawb nrhiav kev txiav txim siab yuav khoom,Dialysis koob lojkev sib piv yog ib qho tseem ceeb tshaj plaws. Cov neeg yuav khoom feem ntau nrhiav 14G-17G kev xaiv nyob ntawm tus neeg mob vascular mob thiab cov hom phiaj kho mob.
Vim li cas ib rab koob tsis tuaj yeem hloov rab koob Dialysis
Txawm hais tias ob qho tib si yog cov koob tshuaj kho mob, ib rab koob txhaj tshuaj tsis tu ncua tsis muaj peev xwm tuav cov kua dej ntws tawm. Kev siv tus qauv koob rau hemodialysis yuav ua rau:
Cov ntshav ntws tsis txaus
Muaj kev pheej hmoo ntawm hemolysis
Muaj kev phom sij ntau dua
Tej zaum mob thiab kev puas tsuaj
Kev kho mob tsis ua hauj lwm
Cov koob tshuaj hemodialysis tau txhawb nqa tsis yog qhov loj me tab sis kuj nyob hauv cov qauv. Lawv cov siliconized ntse bevel muab kev nkag mus tau yooj yim, txo kev raug mob thaum rov nkag.
Thaum twg siv Txhua Hom?
| Scenario | Pom zoo koob |
| Kev txhaj tshuaj txhua hnub | Tsis tu ncua koob |
| Kev txhaj tshuaj txhua hnub | Tsis tu ncua koob 23G-25G |
| Ntshav kos duab | Cov koob tsis tu ncua lossis rab koob npauj npaim |
| Mob raum mob dialysis | Dialysis koob (14G-17G) |
| AV fistula puncture | 15G AV fistula koob nyiam |
Yog tias tus neeg mob tau lim ntshav peb zaug hauv ib lub lis piam, siv lub koob fistula txhim khu kev qha yog qhov yuav tsum tau ua kom muaj kev noj qab haus huv ntawm cov hlab ntsha thiab kev kho mob.
Kev Lag Luam Kev Lag Luam thiab Kev Pom Zoo Thoob Ntiaj Teb
Nrog rau cov kab mob raum ntev zuj zus thoob ntiaj teb, qhov kev thov rau cov khoom siv kho mob xws li cov koob tshuaj lim ntshav tseem nce ntxiv. Tam sim no ntau manufacturers tshwj xeeb hauv:
Sterile, ib leeg-siv dialysis koob
Xim-coded ntsuas qhov loj me
Siliconized thiab rov qab-qhov muag tip designs
Tubing thiab luer connector systems
Kev tshawb nrhiav zoo li koob tshuaj lim ntshav vs koob tsis tu ncua, koob tshuaj lim ntshav sib piv, thiab 15G AV fistula koob qhia tau hais tias muaj kev sib tw thoob ntiaj teb, ua rau lub ntsiab lus tseem ceeb rau cov neeg muag khoom kho mob, e-lag luam platforms, thiab pab pawg muag khoom.
Xaus
Ob lub koob tshuaj niaj hnub thiab cov koob tshuaj lim ntshav yog cov cuab yeej kho mob tseem ceeb, tab sis lawv tau tsim kho rau lub hom phiaj sib txawv. Ib rab koob tsis tu ncua txhawb nqa cov txheej txheem kho mob, thaum lub koob tshuaj lim ntshav muab cov khoom siv siab rau kev kho hemodialysis. Kev nkag siab txog qhov ntau thiab tsawg ntawm rab koob, kev ua haujlwm ntws, thiab kev sib txawv ntawm cov qauv ua kom muaj kev nyab xeeb dua rau cov neeg mob thiab kev txiav txim siab yuav khoom zoo dua.
Rau ib tus neeg tab tom nrhiav los sib piv cov koob tshuaj lim ntshav vs rab koob tsis tu ncua, qhov tseem ceeb tshaj plaws yog qhov yooj yim:
Tsuas yog ib rab koob dialysis yog tsim rau hemodialysis.
