Thaum peb ntsib nrog cov khoom siv kho mob, cov khoom siv hauv nruab nrog cev lossis cov khoom siv phais, peb feem ntau pom tias lawv yog cov khoom siv dab tsi. Tom qab tag nrho, peb xaiv cov ntaub ntawv tseem ceeb heev. Silicone roj hmab yog cov khoom siv dav siv hauv kev kho mob, thiab nws cov yam ntxwv zoo biocompatibility yog tsim nyog tshawb nrhiav qhov tob. Kab lus no yuav tshawb txog qhov tob ntawm biocompatibility ntawm silicone roj hmab thiab nws daim ntawv thov hauv kev kho mob.
Silicone roj hmab yog cov khoom siv roj ntsha siab molecular uas muaj silicon bonds thiab carbon bonds hauv nws cov qauv tshuaj, yog li nws suav hais tias yog cov khoom siv tsis-organic. Hauv kev kho mob, silicone roj hmab yog dav siv los ua ntau yam khoom siv kho mob thiab cov khoom siv kho mob, xws li pob qij txha, pacemakers, mis prostheses, catheters thiab lub tshuab ua pa. Ib qho ntawm cov laj thawj tseem ceeb vim li cas cov roj hmab silicone siv dav yog nws cov biocompatibility zoo heev.
Lub biocompatibility ntawm silicone roj hmab feem ntau yog hais txog qhov sib cuam tshuam ntawm cov khoom siv thiab tib neeg cov ntaub so ntswg, ntshav thiab lwm yam kua dej lom. Ntawm lawv, cov cim qhia feem ntau suav nrog cytotoxicity, inflammatory teb, tiv thaiv kab mob thiab thrombosis.
Ua ntej tshaj plaws, cytotoxicity ntawm silicone roj hmab yog tsawg heev. Qhov no txhais tau hais tias thaum silicone roj hmab los rau hauv kev sib cuag nrog tib neeg lub hlwb, nws yuav tsis ua rau muaj kev tsis zoo rau lawv. Es tsis txhob, nws muaj peev xwm cuam tshuam nrog cell nto proteins thiab txhawb cov ntaub so ntswg regeneration thiab kho los ntawm kev khi rau lawv. Cov nyhuv no ua rau cov roj hmab silicone yog cov khoom tseem ceeb hauv ntau thaj chaw biomedical.
Thib ob, silicone roj hmab kuj tsis ua rau muaj kev cuam tshuam loj heev. Hauv tib neeg lub cev, cov lus teb inflammatory yog ib qho kev tiv thaiv tus kheej uas tau pib thaum lub cev raug mob los yog kis kab mob los tiv thaiv lub cev los ntawm kev puas tsuaj ntxiv. Txawm li cas los xij, yog tias cov khoom siv nws tus kheej ua rau cov lus teb inflammatory, nws tsis haum rau kev siv hauv kev kho mob. Hmoov zoo, silicone roj hmab muaj qhov tsis tshua muaj inflammatory reactivity thiab yog li tsis ua rau muaj teeb meem loj rau tib neeg lub cev.
Ntxiv nrog rau cytotoxicity thiab inflammatory teb, silicone roj hmab kuj muaj peev xwm txo tau lub cev tiv thaiv kab mob. Nyob rau hauv tib neeg lub cev, lub cev tiv thaiv kab mob yog ib tug mechanism uas tiv thaiv lub cev los ntawm lwm yam kab mob thiab lwm yam teeb meem. Txawm li cas los xij, thaum cov khoom siv dag zog nkag mus rau hauv lub cev, lub cev tiv thaiv kab mob yuav pom tau tias lawv yog cov khoom txawv teb chaws thiab pib lub cev tiv thaiv kab mob. Qhov kev tiv thaiv kab mob no tuaj yeem ua rau mob tsis tsim nyog thiab lwm yam tsis zoo. Hauv qhov sib piv, lub cev tiv thaiv kab mob ntawm silicone roj hmab yog qhov tsawg heev, uas txhais tau hais tias nws tuaj yeem nyob hauv tib neeg lub cev tau ntev yam tsis muaj kev tiv thaiv kab mob.
Thaum kawg, silicone roj hmab kuj muaj cov khoom tiv thaiv thrombotic. Thrombosis yog ib yam kab mob uas ua rau cov ntshav coagulate thiab ua rau txhaws. Yog tias cov ntshav txhaws tawm thiab thauj mus rau lwm qhov chaw, nws tuaj yeem ua rau mob plawv, mob stroke, thiab lwm yam teebmeem kev noj qab haus huv. Silicone roj hmab tuaj yeem tiv thaiv thrombosis thiab tuaj yeem siv rau hauv cov khoom siv xws li lub plawv li qub, tiv thaiv cov teeb meem kev noj qab haus huv xws li kab mob plawv thiab mob stroke.
Hauv luv luv, biocompatibility ntawm silicone roj hmab yog qhov zoo heev, uas ua rau nws yog ib qho tseem ceeb hauv kev kho mob. Vim nws tsis tshua muaj cytotoxicity, tsis tshua muaj inflammatory reactivity, tsis tshua muaj immunoreactivity thiab anti-thrombotic yam ntxwv, silicone roj hmab tuaj yeem siv dav hauv kev tsim cov khoom siv hauv nruab nrog cev, cov khoom siv kho mob thiab cov khoom siv phais, thiab lwm yam, los pab cov neeg mob tau txais kev kho mob zoo dua thiab zoo ntawm lub neej.
