Ake sikhulume ngokugqokwa kwe-hydrocolloid. Ingxenye evame kakhulu edonsa amanzi yi-carboxymethyl cellulose (i-CMC ngamafuphi). I-hydrocolloid yamanje inolwelwesi olungangeneki ngaphandle, olungenza inxeba lingangeni moya, lingangeni manzi futhi lingabi nobhaktheriya, Kodwa ingavumela umoya nomhwamuko wamanzi ukuba ungene. Ukwakheka kwalo akuqukethe amanzi. Ngemuva kokumunca i-exudate yesilonda, izokwakha into efana ne-gel ukumboza isilonda ukugcina imvelo yesilonda imanzi, futhi uketshezi olumuncekile, Luqukethe inani elikhulu lama-enzyme, izici zokukhula kanye ne-collagen, ukuze izicubu ze-granulation zikhule zisuke zihlanzekile amanxeba, kanye namanxeba anezicubu ze-necrotic angakhiqiza ukususwa kwe-autologous. Le nto efana ne-gel futhi ivumela ukugqoka ukuthi kususwe ngaphandle kobuhlungu. Okubi ukuthi lapho i-hydrocolloid imunca i-exudate, izoncibilika ibe yijeli emhlophe ene-turbid jelly, futhi izoba nephunga elingathandeki, okuvame ukuthiwa yiphutha futhi isaba ukulisebenzisa (isithombe1). Futhi ikhono layo lokumunca amanzi alinamandla, kuphela ukumunca amanzi kocezu lwe-gauze, ngakho-ke livame ukusetshenziswa kaningana ngosuku lapho lisetshenziselwa ukuklwebheka noma isilonda esijulile. Amanye ama-hydrocolloid aklanywa njengamabala ama-acne noma ama-Bondi patches ukwenza imicimbi ehlukahlukene. Phakathi kwazo, i-J & J's hydrocolloid hydrogel engenawo amanzi futhi ephefumula ibizwa ngokuthi yi-hydrogel, kepha ngesiNgisi yi-Band-Aid Hydro Seal gel hydrocolloid gel, ngakho-ke isabizwa ngokuthi ukugqoka kwe-hydrocolloid. (isithombe1). Ngemuva kokuthi i-hydrocolloid imunce i-exudate, igcwala ijeli ukufeza umphumela wokuthambisa.
Ake sikhulume nge-hydrogel, okuluhlobo lwe-polymer hydrophilic polymer (equkethe i-glycerin noma amanzi). Iphesenti lamanzi lingafinyelela kuma-80% -90%. Njengencazelo engokoqobo, yenzelwe ukuthambisa inxeba nokuthambisa ischar. , Futhi inganikeza umswakama ukuze womise amanxeba ukusiza isilonda sikhiqize umphumela wokuzihlanza. Ifomu le-gel lingaba yi-gel engapheli (asikho isithombe), ishidi (asikho isithombe), noma i-gauze elikhulelweyo (njenge-IntraSite Conformable dressing), noma i-gauze elikhulelweyo (njenge-IntraSite Conformable dressing). Ijeli engapheli ingashintsha kalula i-wet gauze padding, futhi idinga kuphela ukushintshwa kanye ngosuku. Kunomphumela wokunikeza okuthambisa "umsizi onikelayo" kuzicubu ze-necrotic. Ukuthanjiswa nokuswakama koqweqwe kungakhuphula ukukhiqizwa kwe-collanginase ukukhuthaza umphumela we-autodebridement. Kodwa-ke, ngenxa yokuqukethwe kwamanzi amaningi, kufanele kuthathwe ukunakekelwa ukuze kungathintwa isikhumba ukugwema ukungena. Ama-hydrogel amashidi axhumene ngokuhlukile ukuguqula ama-polymer e-hydrogel hydrophilic abe yisimo esiqinile. Ishidi lokuqala elitholakalayo elidayiswa nge-hydrogel lokugqoka amanxeba emlandweni lenziwe nguGeistlich Pharma AG, inkampani ebizwa ngeGeistlich Pharma AG. “IGeely Bao Geliperm” yethulwa ngo-1977. Inamanzi angama-96%, i-agar engu-1%, ne-3% i-polyacrylamide. Isizukulwane sesibili seGeely Bao Geliperm sinezela ngama-35% glycerol, ukuze kuthuthukiswe umthamo wawo wokumunca amanzi. Ngakho-ke, i-gel ne-hydrogel dressings (ama-hydrogels amashidi) anokuqanjwa okufanayo, ngaphandle kokuthi ukugqokiswa kweshidi le-hydrogel kunamanzi amancane ukwenza lula ukumunca inani elincane le-exudate. Njengesikhumba sokufakelwa, zingasetshenziselwa kuphela ukuphuma, futhi zinikeze indawo enomanzi yamanxeba. Kepha uma imunca amanzi, ngeke ivuze ngenxa yokukhama, futhi i-hydrogel enjengeshidi eqinile inomphumela oyingqayizivele "wokupholisa" nokuthambisa esikhunjeni, ngakho-ke ingasetshenziselwa ukushisa namanxeba abuhlungu (Uma kunesidingo, ngaphansi imibandela ethile, ukugqoka okucwebezelayo kwe-hydrogel nakho kungafakwa esiqandisini kuqala, bese kukhishwa lapho kusetshenziselwa ukudlala umphumela wokupholisa). Ngaphezu kwalokho, ingasetshenziselwa ukwelapha ingxibongo nezinkukhu. , Futhi ngoba kusobala, kulula ukubona inxeba. Lolu hlobo lokugqoka amashidi luvame ukufaka ungqimba lwefilimu engenamanzi ngaphandle ukuvimbela ukulahleka kwamanzi, ukuvimbela ijeli ukuthi likhishwe futhi kwandise amandla ayo okunamathela ukuyivimba ukuthi ingawi. Lolu hlobo lokugqoka ngeke lumunce amanzi kahle futhi alinakusetshenziselwa amanxeba anamanzi amaningi noma ukutheleleka, ngaphandle kwalokho kulula ukukhiqiza ukungena kwesikhumba esizungeze isilonda, okuzoba nokunambitheka noma amabhamuza aminyene, noma kuzothuthukisa ukwanda kwamagciwane enxebeni elinegciwane. . Ngokwencwadi yokufunda, lokhu kugqokwa kwe-hydrogel empeleni kufanelekile kunoma yimaphi amanxeba angaphezulu, njengokusha kwesibili, amanxeba ezinyawo zikashukela, ukulimala okuchobozekile, noma imihuzuko. Uma isithako esiyinhloko se-hydrogel enjengeshidi singamanzi, lapho sisetshenziswa enxebeni elivulekile, kufanele lisikwe ukuze lilingane nesimo senxeba. Ungasithinti isikhumba esiseduze kwesilonda ukugwema ukungena. Kodwa-ke, uma isithako esiyinhloko yi-glycerin, i-hydrogel enjengeshidi ingasetshenziswa esikhumbeni esiseduze kwesilonda. Kukhona amathuba amancane okungena, kepha lolu hlobo lokugqoka olususelwa ku-glycerin aluvamile.
Njengoba ukugqokwa kweshidi le-hydrogel kunezinzuzo eziningi kangaka, kungani zingasasetshenziswa kakhulu embonini yamanxeba kuze kube manje? Ngicabanga ukuthi into ebaluleke kunazo zonke intengo, futhi kunemikhiqizo eminingi kakhulu ehlukile (enjengokotini lwasolwandle, ukugqoka nge-hydrocolloid, amagwebu e-PU, njll.).
