Endotracheal tube PVC tebchaw, tseem hu ua polyvinyl chloride tebchaw, xa mus rau cov ntaub ntawv tshwj xeeb siv hauv kev tsim cov raj endotracheal.Cov hlab ntsha endotracheal yog cov cuab yeej siv kho mob siv los tsim thiab tswj txoj hlab cua qhib thaum lub sijhawm phais lossis hauv cov neeg mob hnyav uas yuav tsum tau siv tshuab ua pa.PVC cov khoom siv hauv cov hlab ntsha endotracheal tau ua tib zoo tsim kom tau raws li qhov yuav tsum tau ua ntawm daim ntawv thov kev kho mob tseem ceeb no.Cov tshuaj no yog tsim los ua biocompatible thiab non-toxic, kom ntseeg tau tias lawv tsis ua rau muaj kev phiv los yog ua mob rau tus neeg mob txoj kev ua pa los yog ua pa system.Cov PVC tebchaw siv nyob rau hauv endotracheal hlab yuav tsum muaj tej yam kev mob ntawm lub cev kom ua tau zoo.Lawv yuav tsum tau hloov pauv tsis tau muaj zog txaus los tswj cov duab ntawm lub raj thaum siv thiab siv.Cov tebchaw no kuj tseem yuav tiv taus kinking lossis collapsing, ua kom cov cua ntws zoo rau tus neeg mob lub ntsws. Tsis tas li ntawd, cov khoom siv PVC siv rau hauv cov hlab ntsha endotracheal tej zaum yuav muaj cov khoom ntxiv los txhim kho cov khoom tshwj xeeb.Piv txwv li, radiopaque additives tuaj yeem suav nrog los ua kom pom kev pom nyob rau hauv X-ray duab, ua kom yooj yim rau kev kuaj xyuas cov raj kom raug.Anti-microbial additives kuj tseem siv tau los txo qhov kev pheej hmoo ntawm kev kis kab mob cuam tshuam nrog kev siv lub raj ntev ntev.Txawm li cas los xij, nws tsim nyog hais tias PVC raws li cov khoom siv tau ntsib qee qhov kev txhawj xeeb ntawm nws qhov cuam tshuam rau ib puag ncig thiab tib neeg kev noj qab haus huv.Raws li qhov tshwm sim, cov kws tshawb fawb thiab cov tuam txhab lag luam tau nquag tshawb nrhiav lwm cov ntaub ntawv thiab thev naus laus zis rau cov hlab ntsha endotracheal uas tuaj yeem muaj qhov zoo sib xws lossis txhim kho kev ua tau zoo thaum hais txog cov kev txhawj xeeb no.Nyob rau hauv cov ntsiab lus, endotracheal tube PVC tebchaw yog tshwj xeeb tsim cov ntaub ntawv siv hauv kev tsim cov raj endotracheal.Cov tebchaw no yog tsim los ua kom biocompatible, yoog raws, thiab muaj zog, ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo thaum lub sijhawm phais lossis tshuab cua tshuab hauv cov neeg mob hnyav.
