Kodi PDLLA Poly(DL-lactide) CAS 51056-13-9 ndi chiyani?

PDLLA ndi polima yopanda mawonekedwe yokhala ndi kutentha kwa galasi kwa 50-60℃ komanso kukhuthala kwa 0.2-7.0dl/g. Zipangizozi zavomerezedwa ndi FDA ndipo zitha kugwiritsidwa ntchito ngati chothandizira pa mucosa yolimbana ndi zomatira, ma microcapsules, ma microspheres ndi ma implants kuti zitulutsidwe nthawi zonse, ndipo zitha kugwiritsidwanso ntchito ngati ma scaffold oboola minofu ndi kukonza mafupa kapena zinthu zokonzera minofu, monga ma suture ochitira opaleshoni, ma implants, khungu lochita kupanga, mitsempha yamagazi yochita kupanga, ndi maso.

Kugwiritsa ntchito

‌1. Kukongoletsa nkhope: PDLLA imagwiritsidwa ntchito kwambiri ngati chodzaza nkhope m'munda wa kukongoletsa nkhope chifukwa cha kugwirizana kwake bwino komanso kuwonongeka kwake. Ikhoza kulimbikitsa kupanga kolajeni pakhungu, motero imapangitsa khungu kukhala lopindika, makwinya ndi kupsinjika.

‌2. Zipangizo zachipatala‌: PDLLA imagwiritsidwanso ntchito kwambiri pazida zachipatala, monga zophimba zodzaza ndi mankhwala a stents ya mtima yoonongeka, ma suture opareshoni, ma hemostatic clips, ndi zina zotero. Kugwirizana kwake bwino ndi kuwonongeka kwa thupi kumapangitsa kuti zida zachipatalazi zikhale zotetezeka komanso zogwira mtima kwambiri zikagwiritsidwa ntchito.

‌3. Uinjiniya wa minofu‌: PDLLA imagwiranso ntchito zofunika kwambiri pakupanga minofu, monga kukonza mafupa ndi zinthu zokonzera mafupa, ma scaffolds a uinjiniya wa minofu, ndi zina zotero. Kapangidwe kake ka machubu kamapangitsa kuti maselo azilumikizana komanso kukula, motero kumalimbikitsa kukonzanso minofu ndi kubwezeretsanso.

4. Kutulutsa mankhwala motsogozedwa ndi mankhwala: PDLLA ingagwiritsidwenso ntchito potulutsa mankhwala motsogozedwa ndi mankhwala komanso kuyika mankhwala motsogozedwa ndi mankhwala. Mwa kuphatikiza ndi mankhwala kuti apange mitundu ya mlingo monga ma microspheres kapena ma microcapsules, kutulutsa mankhwala pang'onopang'ono komanso kugwira ntchito motsogozedwa ndi mankhwala kumatha kuchitika, motero kupititsa patsogolo kugwira ntchito bwino komanso chitetezo cha mankhwala.

‌5. Kuwonongeka kwa PDLLA: PDLLA imawonongeka pang'onopang'ono, zomwe zimathandiza kuti ipereke zotsatira zochiritsira kwa nthawi yayitali mu ntchito zachipatala. Chogulitsa chake chowonongeka ndi lactic acid, chomwe pamapeto pake chimasinthidwa kukhala carbon dioxide ndi madzi, ndipo sichimayambitsa poizoni komanso chovulaza thupi la munthu‌
