Ngatitaurei nezve hydrocolloid kupfeka. Chinhu chinowanzozivikanwa chinotora mvura ndeye carboxymethyl cellulose (CMC ipfupi). Iyo yazvino hydrocolloid ine semi-inokwanisika membrane kunze, iyo inogona kuita kuti ronda risapinda mweya, isapinda mvura uye bhakitiriya-chiratidzo, Asi inogona kubvumira mweya uye mvura mhute kuti ipinde. Kuumbwa kwaro hakuna mvura. Mushure mekumedza ronda exudate, ichaumba chinhu chakaita sejeri kuvhara ronda rekuchengetedza ronda nharaunda, uye iyo inoyerera tishu yemvura, Ine huwandu hwakawanda hwema enzymes, zvinhu zvekukura uye collagen, kuitira kuti granulation tishu inogona kukura kubva pakachena maronda, uye maronda ane necrotic tishu anogona kuburitsa autologous debridement. Ichi chinhu chakaita sejeri chinobvumirawo kuti kupfeka kubviswe pasina kurwadziwa. Izvo zvinokanganisa ndezvekuti iyo hydrocolloid painotora iyo exudate, inozonyungudika kuita chena turbid jelly, uye ichave nekunhuhwirira kusingafadzi, uko kunowanzo kanganisirwa nekuda kwethumba uye kunotya kuishandisa (pikicha1). Uye kugona kwayo kwekutora mvura hakuna kusimba, chete nezvekupinza mvura kwechimedu che gauze, saka inowanzo shandiswa kakati wandei pazuva apo inoshandiswa kukwenya kana ronda rakadzika. Mamwe mahydrocolloid akatogadzirwa seacne patches kana maBondi patches kufambisa akasiyana zviitiko. Pakati pavo, J & J's hydrocolloid hydrogel isina mvura uye inofema inotambanuka inonzi hydrogel, asi muChirungu ndiyo Band-Aid Hydro Seal hydrocolloid gel, saka ichiri kuisirwa seye hydrocolloid kupfeka. (mufananidzo1). Mushure mekunge hydrocolloid yapinza iyo exudate, inozvimba ichiita gel kuti ibudirire.
Ngatitaurei nezve hydrogel, iri mhando yemubatanidzwa hydrophilic polymer (ine glycerin kana mvura). Iyo mvura muzana inogona kukwirira se80% -90%. Seizvo chaizvo zvinoreva, zvakagadzirirwa kunyorovesa ronda uye kupomhodza eschar. , Uye inogona kupa hunyoro kuomesa maronda kubatsira iyo ronda kuburitsa yekuzvinatsa-yega maitiro. Iyo fomu yegel inogona kuve isingagumi gel (isina pikicha), jira (hapana pikicha), kana akaiswa nhumbu gauze (senge IntraSite Conformable kupfeka), kana inoiswa nhumbu gauze (senge IntraSite Conformable kupfeka). Isingagumi gel inogona nyore kutsiva yakanyorova gauze padding, uye inongoda kutsiviwa kamwe pazuva. Iyo ine mhedzisiro yekupa iyo yekunyorovesa "humoni mupi" kune necrotic tishu. Iko kupfava uye kunyorova kweiyo goko kunogona kuwedzera kugadzirwa kwecollanginase kusimudzira otodebridement mhedzisiro. Nekudaro, nekuda kwehuwandu hwayo hwemvura, chengetedzo inofanira kutorwa kwete kubata ganda kudzivirira kupinda mukati. Sheet hydrogels akayambuka-akabatanidza kushandura hydrogel hydrophilic polymers kuita solid state. Yekutanga kutengeswa inowanika pepa rehydrogel kupfeka maronda munhoroondo yakagadzirwa naGeistlich Pharma AG, kambani inonzi Geistlich Pharma AG. "Geely Bao Geliperm" yakavhurwa muna 1977. Iine 96% mvura, 1% agar, uye 3% polyacrylamide. Chizvarwa chechipiri cheGeely Bao Geliperm chinowedzera 35% glycerol, kuitira kusimudzira kugona kwayo kwemvura. Naizvozvo, gel uye hydrogel yekupfeka (sheet hydrogels) ine nziyo dzakafanana, kunze kwekunge machira ehydrogel akapfekerwa ane mashoma emvura zvemukati kufambisa kunwiwa kweiyo shoma exudate. Seganda rekugadzira, ivo vanongogona chete kushandiswa kune exudation, uye nekupa inovhenekera nharaunda yemaronda. Asi painotora mvura, haizodonhe nekuda kwekusvisvina, uye iyo jira-yakaita hydrogel ine yakasarudzika "kutonhora" uye inozorodza paganda, saka inogona kushandiswa pakupisa uye maronda anorwadza (Kana zvichidikanwa, pasi mamwe mamiriro, iyo isina simba hydrogel kupfeka inogona zvakare kuiswa mufiriji mufiriji kutanga, uye wozoburitswa kunze apo painoshandiswa kutamba inotonhorera maitiro). Uye zvakare, inogona zvakare kushandiswa kurapa chickenpox uye shingles. , Uye nekuti iri pachena, zviri nyore kuti utarise ronda. Rudzi urwu rwekupfeka machira rinowanzo wedzera firimu risingadziviri mvura kunze kwekudzivirira kurasikirwa nemvura, kudzivirira gel kuti isasvinirwe kunze uye kuwedzera simba rayo rekunamatira kuti rirege kudonha. Rudzi urwu rwekupfeka harugone kunwisa mvura zvakanaka uye harugone kushandiswa kumaronda ane zvakawandisa mvura kana hutachiona, zvikasadaro zviri nyore kuburitsa kupinda kweganda rakatenderedza ronda, iro rinenge riine kuravira kana mhoni dzakakora, kana richasimudzira kuwanda. yebhakitiriya muronda rine hutachiona. . Zvinoenderana nebhuku racho, kupfeka kwehydrogel kwakanyatsokodzera maronda epamusoro, akadai sekutsva kwechipiri-degree, maronda etsoka yeshuga, kukuvara kwekupwanya, kana kupwanya. Kana chinhu chikuru cheshizha-senge hydrogel imvura, kana chashandiswa muronda rakavhurika, chinofanirwa kutemwa kuti chikwane chimiro chevanga. Usabata ganda riri padyo neronda kuti usapinda. Nekudaro, kana chinhu chikuru chiri glycerin, jira-senge hydrogel inogona kuiswa kune ganda riri padyo neronda. Iko kune mukana mushoma wekupinda, asi iyi mhando yeglycerin-based kupfeka haiwanzo.
Sezvo machira ehydrogel akapfekedzwa ane zvakawanda zvakanakira, nei achiri asiri anowanzo shandiswa muindasitiri yemaronda kusvika zvino? Ini ndinofunga chakanyanya kukosha mutengo, uye kune zvakawanda zvakawandisa zvigadzirwa (senge yegungwa donje, hydrocolloid kupfeka, PU furo, nezvimwewo).
