Me korero e pā ana ki te whakakakahu hydrocolloid. Ko te waahanga noa e mimiti ana i te wai ko te carboxymethyl cellulose (CMC mo te poto). Ko te hydrocolloid o naianei, he membrane parawhe-permeable kei waho, e taea ai te pupuhi o te hau, te waikore me te totika-engari, ka taea te uru ki te hau me te kohu wai. Kaore he wai o roto. I muri i te ngongo o te whara ki te whara, ka puta he taonga rite ki te gel hei kapi i te patunga kia makuku tonu te taiao o te whara, me te waipiro mimiti o te kiko, Kei roto te nui o te whākōkī, ngā tipu tipu me te collagen, kia tupu ake ai te kiko o te granulation mai i te ma. nga whara, me nga whara me nga kiko kiko ka taea te whakaputa i te otaota autologous. Ko tenei taonga rite ki te gel ka taea te tango i nga kakahu kaore he mamae. Ko te ngoikoretanga ina ka ngongo te waikawa i te exudate, ka rewa atu ki roto i te tiere turara ma, ka piro te kakara, ka pohehe tonu te ahua o te koretake, ka mataku ki te whakamahi (pikitia1). Kaore hoki i te kaha te kaha o te mimiti o te wai, engari mo te mimiti o te wai ki te waahanga whiti, no reira he maha nga wa e whakamahia ana i te ra ka whakamahia mo te pakaru, te whara hohonu ranei. Ko etahi hydrocolloids he mea hangaia hei papaki hakihaki, hei taapiri Bondi ranei hei awhina i nga momo huihuinga. I roto i era, ko te hydrogel hydrolel a J & J e kiia ana i te waikore me te manawa e kiia ana ko te hydrogel, engari i te reo Ingarihi ko te Band-Aid Hydro Seal Hydro Seal hydrocolloid gel, no reira ka tohatohahia tonu hei whakakakahu hydrocolloid. (pikitia1). Whai muri i te ngongo o te hydrocolloid i te exudate, ka pupuhi ki roto i te gel hei whakatutuki i te ngoikoretanga.
Me korero mo te hydrogel, he momo polymer hydrophilic pūhui (kei roto te glycerin he wai ranei). Ko te ōrau o te wai ka taea te teitei ki te 80% -90%. Hei tikanga pono, he mea hangaia hei whakamakuku i te maru, kia ngohengohe ai te huha. , Ka taea hoki te whakarato i te houku ki nga maroke maroke hei awhina i te patunga ki te whakaputa i a ia ake mahi horoi. Ko te ahua o te kapi he reera tuturu (kaore he pikitia), he pepa (kaore he pikitia), he whariki ranei (penei i te whakakotahitanga IntraSite Whakakakahu), hei whariki ranei (penei i te whakakakahu IntraSite Whakahoahoa). Ma te kore e tutuki te waatea ka taea te whakakapi i te papa ruri ma, a me huri noa i te ra. He paanga ki te whakarato i tetahi "kaituku makuku" hou ki nga kiko kiko. Ma te ngohengohe me te whakamakuku o te kiri ka taea te whakanui ake i te collanginase hei whakatairanga i te painga autodebridement. Heoi, na te nui o te wai, me tupato kei pa ki te kiri kia kore ai e uru atu. He honoa hono te huringa hauwai hei huri i te waerau hydrogel hydrophilic ki te ahua totoka. Ko te kakahu kakahu hydrogel tuatahi e waatea ana mo nga whara i roto i te hitori i hangaia e Geistlich Pharma AG, he kamupene e kiia nei ko Geistlich Pharma AG. I whakarewahia a "Geely Bao Geliperm" i te 1977. Kei roto ko te wai 96%, 1% agar, me te 3% polyacrylamide. Ko te whakatupuranga tuarua o Geely Bao Geliperm e taapiri ana i te 35% glycerol, hei whakatairanga i te kaha o te mimiti o te wai. No reira, he rite te tito o te gel me te kakahu hydrogel (pepa hydrogels), haunga ko nga takai hydrogel pepa he iti ake te wai hei whakapiki i te ngongo o te waahanga nui. Ka rite ki te hiako horihori, ka taea noa te whakamahi mo te whakaraerae, me te whakarato i tetahi taiao maana mo nga patunga. Engari ka mimiti ana te wai, e kore e rere atu na te kaha o te kotuku, a, ko te hydrogel-peera totoka he "whakamaoatanga" me te whakamarie i te kiri, na ka taea te whakamahi mo te weranga me nga whara mamae (Ki te tika, i raro etahi tikanga, ko te whakakakahu hydrogel flaky ka taea hoki te pouaka o te pouaka whakamātao i te tuatahi, ka whakaputaina ka whakamahia ana kia pai ai te whakamatao). Hei taapiri, ka taea hoki te whakamahi hei hamani i te paukena me te piu. , Ana na te mea he maarama, he pai ki te tirotiro i te patunga. Ko tenei momo whakakakahu pepa ka taapirihia he waahanga o te kiriata parewai i waho hei aukati i te ngaronga o te wai, kia kore ai e romia te gel kia kaha ake te kaha piri ki te aukati kia hinga. Ko tenei momo whakakakahu kaore e ngongo pai ki te wai, kaore hoki e taea te whakamahi mo nga whara me te nui o te wai ka pangia ranei, ki te kore he ngawari ki te whakaputa i te kiri ki te tua o te whara, ka reka, ka pupuhi ranei te matotoru, ka whakatairanga ranei i te tini. o te kitakita i te patunga kua pangia. . E ai ki te pukapuka pukapuka, ko tenei kakahu whakakakahu hydrogel he mea tika mo nga whara kino, penei i te weranga tuarua, whara waewae huka, maru pakaru, maru ranei. Mena ko te waahanga matua o te hydrogel pera i te rau he wai, ka whakamahia ana i roto i te whara tuwhera, me tapahi kia uru ki te ahua o te whara. Kaua e pa ki te kiri i te taha o te whara kia kore ai e uru atu. Heoi, mena ko te mea nui ko te glycerin, ka taea te kiri-penei te hydrogel ki te kiri i te taha o te patunga. He iti noa te tuponotanga, engari ko tenei momo whakakakahu mo te glycerin he uaua.
Na te mea he maha nga painga o nga kakahu haehae hydrogel, he aha i kore ai e whakamahia i roto i te umanga whara a mohoa noa nei? Ki taku whakaaro ko te mea nui ko te utu, ana he maha rawa nga hua rereke (penei i te miro rimurimu, te whakakakahu hydrocolloid, PU foam, me era atu).
