Taw qhia
Cov cuab yeej kho mob yog ib feem tseem ceeb ntawm cov kev pab kho mob. Nws pab cov kws kho mob thiab cov kws kho mob hauv kev kuaj mob, saib xyuas, thiab kho cov neeg mob. Cov khoom siv kho mob, tshwj xeeb tshaj yog cov khoom siv pov tseg, yog ua los ntawm cov yas vim lawv cov khoom tshwj xeeb xws li kev ua haujlwm ntev, yooj yim, hnav, thiab pheej yig. Qhov tseem ceeb ntawm cov yas hauv kev lag luam kho mob yog qhov tsis xav txog, thiab nws qhov kev thov nce ntxiv. Hauv tsab xov xwm no, peb yuav tham txog ntau yam yas siv hauv kev lag luam khoom siv kho mob.
Hom yas
#1) Polyvinyl Chloride (PVC)
PVC yog siv dav siv thermoplastic polymer hauv cov khoom siv kho mob. Nws yog lub npe hu rau nws cov tshuaj tiv thaiv zoo heev, durability, thiab yooj. PVC yog siv rau hauv daim ntawv thov xws li IV hnab, tubing, thiab cov hnab ntshav. Ib qho zoo ntawm PVC yog tias nws tuaj yeem ua kom tsis muaj menyuam tsis muaj kev cuam tshuam rau nws cov khoom. PVC yeej tsis siv rau hauv cov khoom siv kho mob uas tuaj yeem tiv nrog cov ntshav lossis tib neeg cov ntaub so ntswg vim nws tso cov yas yas, uas tuaj yeem ua rau tib neeg noj qab haus huv.
#2) Polyethylene (PE)
PE yog cov yas ntau tshaj plaws hauv ntiaj teb, thiab nws muaj ntau daim ntawv thov hauv kev lag luam khoom siv kho mob. Nws yog ib lub teeb yuag, ruaj khov, thiab hloov tau yooj yim uas tuaj yeem ua kom tsis muaj menyuam tsis muaj zog. PE yog siv rau hauv cov ntawv thov xws li cov raj xa dej, hnab yas, thiab cov hnab looj tes pov tseg.
#3) Polycarbonate (PC)
PC yog ib qho tawv tawv, pob tshab yas uas siv rau hauv cov khoom siv kho mob uas xav tau lub zog siab, ua haujlwm ntev, thiab biocompatibility. Nws muaj kev cuam tshuam zoo heev thiab thermal stability, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov khoom siv kho mob xws li lub tshuab ua pa, incubators, thiab cov khoom siv kho mob.
#4) Polystyrene (PS)
PS yog cov yas pob tshab, tawv tawv uas siv rau hauv cov khoom siv kho mob uas xav tau kom pom tseeb thiab nruj. Nws yog siv rau hauv daim ntawv thov xws li Petri Dishes, lub hau pov tseg, thiab cov raj coj mus kuaj.
#5) Polymethyl Methacrylate (PMMA)
PMMA yog cov yas pob tshab, tawv tawv siv hauv cov khoom siv kho mob uas xav tau qhov pom tseeb thiab lub zog zoo. Nws yog siv nyob rau hauv daim ntawv thov xws li intraocular lo ntsiab muag, kho mob implants, thiab prosthetic hips.
Biocompatibility
Thaum cov yas siv rau hauv cov khoom siv kho mob, nws yog ib qho tseem ceeb los xyuas kom meej tias lawv yog biocompatible. Biocompatibility yog lub peev xwm ntawm cov yas los cuam tshuam nrog tib neeg lub cev yam tsis muaj tshuaj lom lossis tshuaj tiv thaiv kab mob. Biocompatibility yog qhov tseem ceeb vim tias cov yas siv yuav tsum muaj kev nyab xeeb rau tib neeg siv. Cov yas siv hauv cov cuab yeej kho mob yuav tsum tau kuaj xyuas nruj kom txiav txim siab lawv cov biocompatibility.
Sterilization
Sterilization yog txheej txheem ntawm kev tshem tawm tag nrho cov kab mob, kab mob, thiab lwm yam kab mob los ntawm cov cuab yeej kho mob. Sterilization yog ua tiav los ntawm ntau txoj kev xws li chav, ethylene oxide, hydrogen peroxide, thiab gamma hluav taws xob. Cov yas siv hauv cov khoom siv kho mob yuav tsum muaj peev xwm tiv taus cov txheej txheem no kom tsis muaj menyuam tsis muaj kev puas tsuaj lossis cuam tshuam rau nws cov khoom.
Kev pov tseg
Kev pov tseg cov cuab yeej kho mob yog qhov tseem ceeb, thiab nws yuav tsum tau ua kom muaj kev nyab xeeb kom tsis txhob muaj kev puas tsuaj ib puag ncig. Cov yas siv hauv cov khoom siv kho mob tsis yog ib txwm biodegradable, thiab yog li, nws yuav tsum muab pov tseg kom zoo. Cov yas uas siv rau hauv cov cuab yeej kho mob yuav tsum tau muab pov tseg, rov siv dua, lossis pov tseg hauv qhov chaw pov tseg. Kev pov tseg cov cuab yeej kho mob yog tswj hwm los ntawm ntau yam kev cai thiab kev cai lij choj.
Xaus
Kev siv cov yas hauv cov cuab yeej kho mob tau hloov pauv kev lag luam kho mob. Ntau hom yas siv rau hauv cov khoom siv kho mob muaj cov khoom tshwj xeeb, ua rau lawv haum rau kev siv sib txawv. Txhawm rau kom cov neeg mob muaj kev nyab xeeb, cov yas siv hauv cov khoom siv kho mob yuav tsum tau kuaj xyuas kom zoo rau biocompatibility. Sterilization kuj yog ib txoj hauv kev tseem ceeb uas cov yas siv hauv cov khoom siv kho mob yuav tsum muaj peev xwm tiv taus. Thaum kawg, pov tseg cov cuab yeej kho mob yuav tsum tau ua kom zoo kom tsis txhob muaj kev puas tsuaj ib puag ncig.
