Kev kho mob Hydrocolloid

Cov khoom no yog kev hnav khaub ncaws ua haujlwm ua los ntawm kev kho mob - qib hydrocolloid cov ntaub ntawv. Nws cov khoom siv hauv paus muaj sodium carboxymethyl cellulose (CMC), pectin, thiab lwm yam hydrocolloid microparticles, ua ke nrog kev kho mob siab -rhiab nplaum matrix, thiab npog nrog polyurethane (PU) semi{3}} permeable membrane. Thaum nyob rau hauv kev sib cuag nrog lub qhov txhab exudate, cov hydrocolloid hais nyob rau hauv lub puab txheej ntawm hnav khaub ncaws zoo nqus cov kua thiab undergo hydration, tsim ib tug mos mos, moist gel txheej. Cov gel txheej no tsis tsuas yog muab qhov chaw zoo noo noo zoo rau lub qhov txhab, txhawb kev tsim kho ntawm epithelial cell regeneration, tab sis kuj tso cai rau tsis mob thiab tsis yog- tawm tsam thaum hnav khaub ncaws hloov pauv yam tsis muaj kev puas tsuaj rau cov ntaub so ntswg tshiab. Cov txheej semi-permeable membrane yog waterproof thiab antibacterial, zoo thaiv cov kab mob sab nraud thaum tso cai rau ib tug haum npaum li cas ntawm cov pa vapor mus rau hauv, tswj qhov sib npaug ntawm qhov txhab microenvironment. Cov khoom yog mos thiab malleable, conforming zoo rau lub cev contours, nrog ib tug nruab nrab tev quab yuam tsim uas minimizes residue thaum tshem tawm. Qhov saum npoo feem ntau muaj kab sib chaws rau kev kho mob yooj yim txiav thiab ntsuas qhov txhab loj.

Haum rau cov qhov txhab ntawm qhov txhab mus rau nruab nrab ntawm qhov txhab uas tsis muaj lossis tsis muaj kab mob me, xws li mob siab (theem I-II), sab hauv venous rwj, kub hnyiab, qhov txhab pub dawb, qhov txhab tom qab phais, daim tawv nqaij abrasions, thiab abrasions; nws kuj tseem siv tau los ua kev kho mob ntxiv rau cov mob ntshav qab zib ko taw. Nws muaj kev siv dav hauv kev saib xyuas qhov txhab mob, kev tswj lub qhov txhab mob, thiab kev tiv thaiv cov cuab yeej kho mob- cuam tshuam txog kev raug mob siab.

Tsis haum rau cov qhov txhab mob hnyav, qhov txhab kis kab mob aerobic lossis anaerobic kab mob, cov kab mob sib sib zog nqus, lossis cov pob txha raug mob lossis cov leeg; contraindicated rau active los ntshav los yog tag nrho - tuab kub hnyiab yuav tsum tau heev cua tshuab; tsis zoo rau cov kab mob uas tshwm sim los ntawm tuberculosis, syphilis, lossis kab mob fungal; contraindicated nyob rau hauv qhov txhab nrog lub zos cov ntaub so ntswg ischemia los yog tej zaum necrosis. Hauv qhov txhab nrog exudate siab heev, maceration yuav tshwm sim tom qab hydrocolloid nqus saturation; siv ceev faj. Contraindicated nyob rau hauv tsawg zaus ntawm hypersensitivity rau hnav khaub ncaws Cheebtsam. Tsis tas li ntawd, cov me nyuam mos hnub nyoog qis dua 2 xyoos thiab cov uas tab tom kho mob ntshav qab zib los yog cov hlab plawv yuav tsum tau sab laj nrog kws kho mob ua ntej siv.
