Tiyeni tikambirane za mavalidwe a hydrocolloid. Gawo lofala kwambiri lomwe limatenga madzi ndi carboxymethyl cellulose (CMC mwachidule). Ma hydrocolloid apano ali ndi nembanemba yopitilira theka kunja, yomwe imatha kupangitsa kuti chilondacho chisatengeke ndimadzi, madzi ndi mabakiteriya, Koma imatha kuloleza mpweya ndi nthunzi yamadzi kulowa. Kapangidwe kake kalibe madzi. Pambuyo poyamwa exudate ya bala, ipanga chinthu chonga gel ngati chophimbira chilondacho kuti chilengedwe chikhale chinyezi, ndipo madzi amadzimadzi, Amakhala ndi michere yambiri, zinthu zokula ndi collagen, kuti minofu ya granulation imere kuchokera mabala, ndipo mabala okhala ndi minofu ya necrotic amatha kupanga kuwonongeka kwa autologous. Chomwe chimakhala ngati gel chimathandizanso kuti mavalidwe achotsedwe popanda kuwawa. Chosavuta ndichakuti hydrocolloid ikatenga exudate, idzasungunuka kukhala jelly yoyera yoyera, ndipo imakhala ndi fungo losasangalatsa, lomwe nthawi zambiri limasokonekera ngati chotupa ndipo limachita mantha kugwiritsa ntchito (chithunzi1). Ndipo kuthekera kwake kwamadzi sikokwanira, kungotengera madzi a chidutswa cha gauze, chifukwa chake amagwiritsidwa ntchito kangapo patsiku akagwiritsa ntchito poyambira kapena pachilonda chakuya. Ma hydrocolloids ena amapangidwanso ngati zigamba zamatenda amtundu kapena mabatani a Bondi kuti athetse zochitika zosiyanasiyana. Pakati pawo, J & J's hydrocolloid hydrogel yopanda madzi komanso yopumira imatchedwa hydrogel, koma m'Chingerezi ndi Band-Aid Hydro Seal hydrocolloid gel, chifukwa chake imadziwika kuti mavalidwe a hydrocolloid. (chithunzi1). Pambuyo pa hydrocolloid imatenga exudate, imafufuma mu gel kuti ikwaniritse mafuta.
Tiyeni tikambirane za hydrogel, yomwe ndi mtundu wa polima hydrophilic polima (wokhala ndi glycerin kapena madzi). Kuchuluka kwamadzi kumatha kukhala 80% -90%. Monga tanthauzo lenileni, lakonzedwa kuti lisunthire bala ndikuchepetsera eschar. , Ndipo imatha kupereka chinyezi kuti ziume mabala kuti zithandizire bala kuti lizitha kudziyeretsa. Maonekedwe a gel amatha kukhala osasintha (osakhala ndi chithunzi), pepala (palibe chithunzi), kapena gauze wopachikidwa (monga IntraSite Conformable dressing), kapena gauze wopachikidwa (monga IntraSite Conformable dressing). Gel osasinthika amatha kusintha m'malo mopyapyala wonyowa, ndipo amangofunika kusinthidwa kamodzi patsiku. Zili ndi mphamvu yopatsa chinyezi "wopereka chinyezi" kumatenda a necrotic. Kuchepetsa ndi kusungunula kwa kutumphuka kumatha kukulitsa kupanga kwa collanginase kuti ikulimbikitseni kuyendetsa kwayokha. Komabe, chifukwa chokhala ndi madzi ambiri, chisamaliro chiyenera kutengedwa kuti chisakhudze khungu kuti lisalowe. Ma sheet a ma hydrogel amaphatikizika kuti asinthe ma polima a hydrogel hydrophilic kukhala olimba. Chovala choyamba kugulitsa ma hydrogel pamankhwala chidapangidwa ndi Geistlich Pharma AG, kampani yotchedwa Geistlich Pharma AG. "Geely Bao Geliperm" idakhazikitsidwa mu 1977. Ili ndi madzi 96%, agar 1%, ndi 3% polyacrylamide. M'badwo wachiwiri wa Geely Bao Geliperm umawonjezera 35% ya glycerol, kuti ilimbikitse kuyamwa kwake kwamadzi. Chifukwa chake, ma gel ndi ma hydrogel (mapepala a ma hydrogel) ali ndi nyimbo zofananira, kupatula kuti ma sheet a hydrogel amakhala ndi madzi ochepa kuti athe kuyamwa pang'ono. Monga khungu lochita kupanga, amatha kugwiritsidwa ntchito potulutsa, ndikupatsanso malo amvula mabala. Koma ikamwetsa madzi, siyimatuluka chifukwa chofinya, ndipo pepala lolimba ngati hydrogel limakhala ndi "kuziziritsa" kwapadera pakhungu, kotero limatha kugwiritsidwa ntchito poyaka ndi zilonda zopweteka (Ngati kuli koyenera, pansi pake Nthawi zina, kuvala kosalala kwa hydrogel kumatha kukhalanso mufiriji m'firiji poyamba, kenako nkuchotsedwa ikamagwiritsidwa ntchito pozizira). Kuphatikiza apo, itha kugwiritsidwanso ntchito kuchiza nthomba ndi ma shingles. , Ndipo popeza ndiyowonekera, ndikofunikira kuwona bala. Mtundu wovekedwa woterewu nthawi zambiri umawonjezera kanema wakunja kunja kuti uteteze madzi, kupewa kuti gelisi isafinyidwe ndikuwonjezera mphamvu yake yomata kuti isagwe. Kuvala kotere sikungatenge madzi bwino ndipo sikungagwiritsidwe ntchito mabala okhala ndi madzimadzi ochulukirapo kapena matenda, apo ayi ndikosavuta kutulutsa kulowetsedwa kwa khungu mozungulira chilondacho, chomwe chimakhala ndi kulawa kapena matuza akulu, kapena chithandizira kufalikira mabakiteriya pachilonda chotenga kachilomboka. . Malinga ndi bukulo, kuvala kwa hydrogel kotereku kumakhaladi koyenera pazilonda zilizonse zakunja, monga kutentha kwachiwiri, zilonda zamiyendo ya ashuga, kuvulala, kapena mabala. Ngati chophatikiza chachikulu cha pepala-ngati hydrogel ndi madzi, akagwiritsidwa ntchito pachilonda chotseguka, ayenera kudula kuti agwirizane ndi mawonekedwe a bala. Musakhudze khungu pafupi ndi chilondacho kuti musalowe. Komabe, ngati chophatikizira chachikulu ndi glycerin, pepala-ngati hydrogel itha kugwiritsidwa ntchito pakhungu pafupi ndi bala. Pali mwayi wochepa wolowera, koma mavalidwe amtundu wa glycerin ndi osowa.
Popeza mavalidwe a pepala a hydrogel ali ndi maubwino ambiri, bwanji osagwiritsidwabe ntchito m'makampani amalonda mpaka pano? Ndikuganiza kuti chofunikira kwambiri ndi mtengo, ndipo pali zinthu zina zambiri (monga thonje lamchere, kuvala ma hydrocolloid, thovu la PU, ndi zina zambiri).
