Thaum ua haujlwm hauv kev saib xyuas kev noj qab haus huv, kev saib xyuas kev noj qab haus huv, lossis ib qho chaw uas muaj ntshav, lub cev, lossis cov neeg ua haujlwm kis tau tus mob, cov neeg ua haujlwm tuaj yeem raug kev pheej hmoo uas ua rau muaj mob hnyav. Hauv cov xwm txheej hnyav, ib qho kev kis tus kab mob hauv cov ntshav tuaj yeem txhais tau tias muaj kev noj qab haus huv mus ntev lossis tsis muaj peev xwm ua haujlwm ntxiv. Cov tswv lag luam muaj lub luag haujlwm raug cai los tiv thaiv lawv cov neeg - tsis yog nrog PPE nkaus xwb, tab sis nrog PPE txoj cai, xaiv kom raug thiab siv tau.
PPE cov khaub ncaws cais tawm ua lub luag haujlwm tseem ceeb hauv cov tswv yim tswj kev kis tus kab mob, tiv thaiv cov neeg ua haujlwm kho mob kom tsis txhob kis cov kab mob tsis zoo thiab tiv thaiv kev kis kab mob los ntawm cov neeg ua haujlwm mus rau cov neeg mob.
Vim li cas kev xaiv khaub ncaws tseem ceeb rau kev tiv thaiv kab mob?
Tsis yog tag nrho cov ris tsho pov tseg muaj kev tiv thaiv tib theem. Xaiv ib lub tsho uas tsis haum rau kev ua haujlwm tuaj yeem ua rau cov neeg ua haujlwm tsis muaj kev tiv thaiv - cov kua dej tuaj yeem nqus tau los ntawm cov ris tsho qis, lossis lub tes tsho tuaj yeem caij thaum lub sijhawm ua haujlwm, nthuav tawm cov tawv nqaij. Hloov pauv, cov ris tsho tshwj xeeb tshaj plaws (siv cov ris tsho hnav ris tsho loj rau kev saib xyuas cov neeg mob niaj hnub) nkim nyiaj txiag uas tuaj yeem siv tau zoo dua lwm qhov.
ANSI/AAMI PB70: 2022 tus qauv tsim cov qauv kev lees paub rau kev xaiv cov ris tsho cais tawm. Nws teeb tsa plaub theem ntawm kev thaiv kev ua tau zoo raws li cov qauv ntsuas - thiab cov ris tsho yuav tsum tau sau npe raws li.
CPE hnav ris tsho muaj kev tiv thaiv dab tsi?
Feem ntau CPE hnav tsoos tsho muaj nyob ntawmAWM Level 2(moderate kua barrier). Qee qhov nkag-theem CPE khaub ncaws tuaj yeem yog Qib 1. AAMI Theem 2 cov khaub ncaws raug sim rau kev tiv thaiv cov dej nkag hauv qhov siab - txaus rau feem ntau tsis yog phais, qis-rau-mob txaws scenarios.
Cov lus hauv qab no qhia txog plaub qib AAMI thiab qhov twg txhua qhov feem ntau siv.
| AWM Level | Barrier Performance | Tej yam siv |
|---|---|---|
| Qib 1 | Tsawg barrier - yooj yim dej tsis kam | Kev saib xyuas cov neeg mob yooj yim, kev cais tus kheej, cov neeg tuaj saib lub tsho, cov chav kho mob txheem |
| Qib 2 | Low-to-moderate fluid barrier – kuaj rau kev nkag mus rau hauv lub siab thiab hydrostatic siab | Ntshav kos, suturing, ICU, chaw kuaj mob pathology, kev kho mob |
| Qib 3 | Cov kua dej nruab nrab - kev tiv thaiv siab dua li Qib 2 | Arterial blood draws, IV insertion, chav kho mob xwm txheej ceev nrog me ntsis txaws |
| Qib 4 | Kev thaiv siab tshaj plaws - tiv thaiv kab mob nkag mus (ASTM F1671) | Cov txheej txheem ua kua dej ntev ntev, qhov chaw phais mob siab, paub tias muaj kab mob los yog cov kab mob hauv ntshav |
Thaum twg koj xav tau lub tsho CPE - thiab thaum twg koj yuav tsum xaiv PE lossis SMS?
CPE vs Basic PE
Basic PE (polyethylene) gowns yog qhov kev xaiv kim tshaj plaws. Lawv muaj cov dej tsis kam tab sis zoo li tawv, nrov, thiab tsis muaj qhov cua. CPE (chlorinated polyethylene) yog ib qho kev hloov pauv polymer - hloov tau yooj yim dua, ntsiag to, thiab tsim kua muag tiv taus ntau dua li tus qauv PE. Rau cov neeg ua haujlwm uas tsis txaus siab txog kev tawm hws los yog hnav ris tsho los ntawm nruab nrab ntawm kev ua haujlwm, kev txav mus rau CPE yog qhov ua tau zoo ntawm tsuas yog 20-30% tus nqi siab dua.
CPE vs SMS
SMS (spunbond-meltblown-spunbond) yog peb-txheej nonwoven ntaub nrog lub meltblown core uas lim cov khoom thiab cov kab mob. SMS yog breathable thiab muaj kev tiv thaiv ntau dua (feem ntau Theem 3 lossis 4), tab sis nws raug nqi ntau dua. CPE hnav ris tsho yog kwv yees li 30-50% pheej yig dua rau ib chav tsev tshaj li qhov sib npaug SMS cais khaub ncaws ntawm qib kev tiv thaiv sib piv. Ntau qhov chaw siv txoj hauv kev sib tw: CPE hnav khaub ncaws rau kev saib xyuas niaj hnub thiab cov txheej txheem qis qis, SMS hnav ris tsho rau cov xwm txheej muaj kev pheej hmoo siab dua xws li kev phais lossis kev paub txog cov txheej txheem aerosol-generating.
Thaum twg koj yuav tsum xaiv CPE?
- Cov tsev kho mob dav dav thiab cov chaw kho mob sab nraud - kev sib cuam tshuam ntawm cov neeg mob txhua hnub uas muaj peev xwm kis tau cov kua dej nruab nrab
- Kev phais hniav - scaling, polishing, me me qhov ncauj phais, qhov twg splatter yog heev tab sis tsis high-volume
- Emergency department - suturing, IV insertion, qhov txhab dej
- Phlebotomy thiab ntshav nqus cov chaw nres tsheb - qhov twg cov ntshav tuaj yeem ua tau
- Cov tsev laus thiab cov laus - kev saib xyuas tsis muaj zog, da dej, hloov ntaub pua chaw
- Laboratories – tuav cov neeg mob qhov chaw uas muaj spillage
CPE khaub ncaws kuj tseem siv sab nraum kev kho mob ib txwm muaj: cov chaw kho tsiaj kho tsiaj, kev ua zaub mov, chaw kho kom zoo nkauj, tattoo studios, thiab pleev xim rau kev lag luam. Cov khoom siv tiv taus cov kua dej, roj, thiab cov rog, ua rau nws haum rau ntau qhov chaw ntub dej lossis qias neeg.
Dab tsi ntxiv koj yuav tsum paub txog CPE hnav ris tsho?
CPE hnav ris tsho tuaj yeem tiv thaiv kab mob?

Rau cov txheej txheem uas paub lossis xav tias yuav kis tau los ntawm huab cua yog ib qho kev txhawj xeeb, yuav tsum hnav khaub ncaws siab dua (SMS Level 3 lossis Theem 4) - nrog rau kev tiv thaiv ua pa tsim nyog.
Puas yog CPE hnav khaub ncaws ua pa?
CPE zaj duab xis nws tus kheej tsis ntxeem tau. Txawm li cas los xij, feem ntau CPE hnav ris tsho yog tsim los nrog qhib rov qab thiab khi kaw, tso cai rau huab cua mus ncig. Rau kev hnav ntev ntev hauv qhov chaw kub - xws li chav xwm txheej kub ntxhov thaum lub caij ntuj sov - lub tsho SMS muaj kev ua pa zoo dua. Rau cov txheej txheem luv luv lossis qhov chaw txias, qhov qhib rov qab rau ntawm CPE hnav ris tsho feem ntau txaus.
