Reka tuvuge kubyerekeranye na hydrocolloid. Ikintu gikunze gukurura amazi ni carboxymethyl selulose (CMC muri make). Hydrocolloide iriho ubu ifite igice cya kabiri cyinjira hanze, gishobora gutuma igikomere kitagira umuyaga, kitarinda amazi na bagiteri, ariko kirashobora gutuma umwuka wumwuka n’amazi byinjira. Ibigize ntabwo birimo amazi. Nyuma yo gukuramo igikomere gisohoka, bizakora ibintu bimeze nka gel kugirango bitwikire igikomere kugirango ibidukikije bikomerekejwe neza, hamwe namazi ya tissue yinjizwamo, Harimo imisemburo myinshi, ibintu bikura hamwe na kolagen, kugirango tissue ya granulation ikure kuva isuku ibikomere, n'ibikomere hamwe nuduce twa nerotic birashobora kubyara autologique debridement. Ibi bintu bisa na gel nabyo bituma imyambarire ikurwaho nta bubabare. Ikibi ni uko iyo hydrocolloide ikuyemo exudate, izashonga muri jele yera yera, kandi ikagira impumuro idashimishije, ikunze kwibeshya ko ibisebe itinya kuyikoresha (ishusho1). Kandi ubushobozi bwayo bwo kwinjiza amazi ntabwo bukomeye, gusa kubijyanye no kwinjiza amazi agace ka gaze, bityo rero gakoreshwa inshuro nyinshi kumunsi iyo gakoreshejwe igikoma cyangwa igikomere cyimbitse. Hydrocolloide imwe nimwe yashizweho nkibishishwa bya acne cyangwa Bondi kugirango byorohereze ibihe bitandukanye. Muri byo, hydrocolloide ya hydrogelloid hydrogel idafite amazi kandi ihumeka neza yitwa hydrogel, ariko mu cyongereza ni Band-Aid Hydro Seal hydrocolloid gel, bityo ikaba ishyirwa mu rwego rwo kwambara hydrocolloide. (ishusho1). Hydrocolloide imaze gukuramo exudate, irabyimba muri gel kugirango igere ku ngaruka nziza.
Reka tuvuge kuri hydrogel, ni ubwoko bwa hydrophilique polymer (irimo glycerine cyangwa amazi). Ijanisha ry'amazi rishobora kugera kuri 80% -90%. Nkibisobanuro nyabyo, byashizweho kugirango bigabanye igikomere no koroshya eschar. , Kandi irashobora gutanga ubushuhe kubikomere byumye kugirango bifashe igikomere gutanga umusaruro wo kwisukura. Imiterere ya gel irashobora kuba gel idasobanutse (nta shusho), urupapuro (nta shusho), cyangwa gaze yatewe (nka IntraSite Conformable dressing), cyangwa gaze yatewe (nko kwambara IntraSite Conformable). Gel idasobanutse irashobora gusimbuza byoroshye padi itose, kandi igomba gusimburwa rimwe kumunsi. Ifite ingaruka zo gutanga "umuterankunga utanga amazi" utanga ingirabuzimafatizo. Kworoshya no gutobora igikonjo birashobora kongera umusaruro wa collanginase kugirango biteze imbere autodebridement. Ariko, kubera amazi menshi, hagomba kwitonderwa kudakora ku ruhu kugirango wirinde kwinjira. Amabati hydrogels arahujwe kugirango ahindure hydrogel hydrophilic polymers kumiterere ikomeye. Impapuro za mbere ziboneka mu bucuruzi hydrogel yambara ibikomere mu mateka yakozwe na Geistlich Pharma AG, isosiyete yitwa Geistlich Pharma AG. “Geely Bao Geliperm” yatangijwe mu 1977. Ifite amazi 96%, agar 1%, na 3% polyacrylamide. Igisekuru cya kabiri cya Geely Bao Geliperm kongeramo 35% glycerol, murwego rwo kuzamura ubushobozi bwo kwinjiza amazi. Kubwibyo, gel hamwe na hydrogel yambara (urupapuro rwa hydrogels) bifite ibice bisa, usibye ko imyenda ya hydrogel yambara ifite amazi make kugirango byoroherezwe kwinjiza gake ya exudate. Nkuruhu rwibihimbano, birashobora gukoreshwa gusa mugusohora, kandi bigatanga ibidukikije bitose kubikomere. Ariko iyo ikuyemo amazi, ntizisohoka kubera gukanda, kandi urupapuro rukomeye rumeze nka hydrogel rufite "gukonjesha" no guhumuriza uruhu rwihariye, kuburyo rushobora gukoreshwa mugutwika no gukomeretsa (Niba bibaye ngombwa, munsi ibintu bimwe na bimwe, kwambara hydrogel ya flake birashobora kandi gukonjeshwa muri firigo mbere, hanyuma bigakurwa mugihe byakoreshejwe mugukonjesha). Byongeye kandi, irashobora kandi gukoreshwa mu kuvura inkoko na shitingi. , Kandi kubera ko bisobanutse, biroroshye kureba igikomere. Ubu bwoko bwo kwambika impapuro busanzwe bwongeramo igice cya firime itagira amazi hanze kugirango birinde gutakaza amazi, kubuza gele gusohoka no kongera imbaraga zifatika kugirango birinde kugwa. Ubu bwoko bwo kwambara ntibuzakurura amazi neza kandi ntibushobora gukoreshwa mubikomere bifite amazi menshi cyangwa kwandura, bitabaye ibyo biroroshye kubyara uruhu rwinjira mubikomere, bizaba bifite uburyohe cyangwa ibibyimba byinshi, cyangwa bizamura ubwiyongere. ya bagiteri mu gikomere cyanduye. . Dukurikije igitabo, iyi myambarire ya hydrogel mu byukuri ikwiriye ibikomere byose bitagaragara, nko gutwikwa mu rwego rwa kabiri, gukomeretsa ibirenge bya diyabete, gukomeretsa, cyangwa gukomeretsa. Niba ibintu by'ingenzi bigize urupapuro rumeze nka hydrogel ari amazi, iyo bikoreshejwe mu gikomere gifunguye, bigomba gucibwa kugirango bihuze imiterere y igikomere. Ntukore ku ruhu iruhande rw'igikomere kugirango wirinde kwinjira. Ariko, niba ibyingenzi byingenzi ari glycerine, urupapuro rumeze nka hydrogel rushobora gukoreshwa kuruhu kuruhande rw igikomere. Hari amahirwe make yo gucengera, ariko ubu bwoko bwo kwambara bushingiye kuri glycerine.
Ko impapuro za hydrogel zambara zifite ibyiza byinshi, kuki zitakoreshwa cyane mubikorwa by ibikomere kugeza ubu? Ndibwira ko icy'ingenzi ari igiciro, kandi hari nibindi bicuruzwa byinshi (nk'ipamba yo mu nyanja, kwambara hydrocolloide, impumu ya PU, nibindi).
