3. Nws muaj cov nyhuv tawm
4. Nws tsim cov gel tiv thaiv cov hlab ntsha xaus thiab daws qhov mob. Nyob rau tib lub sijhawm, nws yuav tsis ua rau kev puas tsuaj thib ob puas tsuaj thaum hloov cov khaub ncaws hnav
5. Nws yog tus kheej - adhesive thiab yooj yim siv
6. Nws muaj kev ua raws zoo, tus neeg siv xav tias xis nyob, thiab cov tsos yog zais
7.
Nws tuaj yeem txuag cov nqi los ntawm kev kho kom zoo
Qhov tsis zoo:
1. Qhov muaj peev xwm nqus tau tsis muaj zog heev, yog li rau kev hnav khaub ncaws exudative heev, lwm yam kev hnav ris tsho feem ntau xav tau los txhim kho qhov ua tau pa
2. Tus nqi tsim nqi yog qhov tseem ceeb
3. Qee tus neeg mob yuav ua xua rau cov khoom xyaw
Nws tuaj yeem hais tias qhov no yog hnav khaub ncaws zoo tshaj plaws. Xyoo los ntawm kev thov kho mob nyob txawv teb chaws txawv teb pom tias cov khaub ncaws hauv hydrocolloid tshwj xeeb yog siv rau mob mob ntev.
Alginate hnav khaub ncaws
Alginate hnav khaub ncaws yog ib qho ntawm cov kev hnav ris tsho tshaj plaws. Lub ntsiab tivthaiv ntawm alginate hnav khaub ncaws yog alginate, uas yog lub ntuj polysaccharate extracted los ntawm seaweed thiab lub ntuj cellulose.
Alginate kev hnav khaub ncaws hnav yog qhov ua kom cov khaub ncaws ua haujlwm nrog kev nqus tau zoo ua ke ntawm alginate. Tom qab cov kab yeeb yaj kiab ntawm kev sib cuag nrog kev sib raug zoo, nws tuaj yeem tsim cov khoom muag muag rau kev kho kom zoo, txhawb kev ua kom zoo thiab hloov kho mob.
Mechanism ntawm Kev Ua:
1. Safe and non-toxic: Alginate medical film is a natural polysaccharide carbohydrate extracted from seaweed. Nws yog cov khoom siv polymer uas tsis muaj tshuaj lom rau tib neeg lub cev thiab tuaj yeem siv kev nyab xeeb.
2. Hygroscopicity: alginate kev ua yeeb yaj kiab kho mob tuaj yeem nqus cov kua sib npaug rau 11 zaug nws tus kheej qhov hnyav.
3. Hemostasis: Alginate kev ua yeeb yaj kiab kev ua yeeb yaj kiab ua rau Ca}}} tuaj yeem txhawb kev tsim ntawm PROTHROMBIN ACTIVATOR thiab ua kom nrawm cov ntshav kev sib nqus ntshav.
4. Gelatinization: nqus lub qhov txhab exudate, kev sib pauv ntawm - / ca2+}}} ion nrog exary, thiab ua ib txheej ntawm kev ruaj khov gel rau lub qhov txhab. Tsim microenvirirment rau lub qhov txhab uas muaj zog rau cov nqaij loj hlob (me ntsis acidic, anaerobic lossis hypoxic, muaj ntsis noo noo).
5. Txhawb cov qhov txhab zoo: anaerobic, anaerobic lossis hypoxic, txhim kho kev ua haujlwm ntawm cov khoom loj thiab kev txhawb nqa ntawm cov kab mob kho kom zoo.
6. Cov khoom siv tshuaj tua kab mob:
①. Kev sib cais zoo, uas cais lub qhov txhab ntawm cov kab mob sab nraud;
②. Cov kabmob phom sij yog tsau hauv cov roj fiber, ua rau muaj cov kab mob uas muaj kev sib tiv tauj thiab txo lub caij nyoog ntawm cov kab mob thiab lub qhov txhab;
③. Ib puag ncig noo noo thiab me ntsis acidic ib puag ncig yog conducive rau lub luag haujlwm ntawm neutrophils, txhim kho cov muaj peev xwm hauv zos cov peev xwm thiab txo qhov tshwm sim ntawm tus kab mob.
7. Txo qhov mob hauv zos: lub hydrogel tsim rau ntawm lub ntsej muag tiv thaiv cov leeg thiab zam sab nraud. Nws tsis yooj yim rau lub qhov txhab, kom tshem tau yooj yim thiab txo qhov mob mob.
8. Txo kev caws pliav tsim: Vim tias tsis muaj kev txob txob lossis kev puas tsuaj rau lub qhov txhab, muaj cov caws pliav ntau.
Qhov Zoo:
1. Lub zog zoo thiab nrawm rau nqus exudate
2. Ua cov gel, uas tuaj yeem ua kom lub qhov txhab zoo ntub thiab tsis {}}}}}}}}}}}} stick stick end, thiab daws qhov mob
3. Txhawb cov qhov txhab zoo;
4. Biodegradable, zoo ib puag ncig kev ua yeeb yam;
5. Txo kev caws pliav;
Qhov tsis zoo:
1. Cov khoom lag luam feem ntau tsis yog tus kheej - cov nplaum thiab xav tau kev hnav khaub ncaws kom kho
2. Tus nqi siab dua
