Ebomini, ngokuqhelekileyo kwenzeka ukuba isandla sinqunywe ngengozi kwaye igazi aliyeki.Inkwenkwe encinci yakwazi ukuyeka ukopha emva kwemizuzwana embalwa ngoncedo lwe-gauze entsha yokuyeka ukopha.Ngaba ngokwenene iyamangalisa?
Inoveli ye-chitosan arterial hemostatic gauze iyeka ukopha ngoko nangoko
Igazi ngumthombo wobomi, kwaye ukopha kakhulu kwegazi ngoyena nobangela wokufa ngenxa yokwenzakala ngengozi.Ehlabathini lonke, abantu abasisi-1.9 sezigidi bayafa nyaka ngamnye ngenxa yokopha kakhulu.“Ukuba umntu unobunzima obuziikhilogram ezingama-70, umlinganiselo wegazi lomzimba umalunga nesi-7 ekhulwini sobunzima bomzimba, oko kukuthi, i-4,900 ml, ukuba ukulahlekelwa kwegazi kungaphezu kwe-1 000 ml ngenxa yokwenzakala ngengozi, kuyingozi ebomini.”Kodwa xa uncedo lwezonyango lufika, uncedo lokuqala oluqhelekileyo kukugquma inxeba ngeetawuli, iimpahla, njl. njl., nto leyo enokusebenza xa umthambo okanye i-capillary isopha, kodwa ukuba umthambo wopha, amanyathelo anjalo okophayo ngokufuthi ayanganelanga.”
Kunyango olungxamisekileyo lwangaphambi kwesibhedlele, ulawulo olusebenzayo lokopha kwezigulane ngexesha lokuqala ngundoqo wokufumana ixesha lonyango kunye nokusindisa ubomi.
Kutshanje, i-chitosan arterial hemostatic gauze entsha ekhawulezayo idumile kwintengiso.Le gauze ine-particle ye-chitosan ekhethekileyo.I-Chitosan granules ibophelelwe kwi-gauze ephezulu evumela ukupakisha ngokukhawuleza kunye nokubambelela okukhulu kwizicubu ezijikelezayo.I-Chitosan granules inamathela kwizicubu ezimanzi kwinxeba, ukuphucula i-tamponade ye-gauze kunye nokulawula ukulahleka kwegazi.
Inkqubo ye-hemostatic ekhethekileyo
Ifunxa amanzi egazini kwaye yenze ijeli edibanisa iiseli ezibomvu zegazi ukuze zenze ihlwili legazi. Ukuyeka ukopha i-100%, beka ngokucophelela inxalenye ye-bandage ye-hemostatic kwindawo yesilonda, itywina (tampon) kwaye ubambe, ucinezele ngezandla zakho. , imizuzu emi-5.Ngeli xesha, igazi liya kuhlutha i-bandage, i-chitosan granules ivuliwe, ikhukhumale kwaye iguquke ibe yijeli enzima.Ubunzima bejeli buya kuvala isitya esophayo, siyeke ukopha, kwaye senze ijeli yokuvala inxeba.Kwangaxeshanye, i-chitosan ibophelela ngeeseli ezibomvu zegazi ukuvelisa iigels, ezinokuthi zithintele ngempumelelo ukungcoliseka kwesibini kwebhaktiriya kwinxeba.
Le gauze ye-hemostatic inokulawula ngokukhawuleza ukopha okuphakathi kunye nokubi okubangelwa kukwenzakala, kubandakanywa nolawulo olusebenzayo lokuphuma komthambo omkhulu phakathi kwemizuzu emithathu, kwaye ayiyi kuvelisa ukuvutha kobushushu.Ukongeza kokulungela ukopha okunzulu komthambo, ingasetyenziselwa amanxeba angaphezulu.Indawo yesilonda ayikhawulelwanga, kwaye intloko, intamo, isifuba, isisu kunye nezinye iindawo zomzimba zingasetyenziswa ngokukhuselekileyo.I-gauze ye-hemostatic ibambelela ngokuqinileyo kwisilonda, inciphisa umngcipheko we-pathogens yegazi, kwaye ihlala kwindawo ngelixa ixhoba lihanjiswa, likhusela ukopha okwesibini.Amahlwili egazi anokujika kwimizuzu nje embalwa emva kokugalelwa enxebeni, kwaye ihlwili kulula kakhulu ukulisusa kwaye linokuhlanjwa lula ngamanzi okanye ngesaline.Indlela yokusebenza yale gauze ye-hemostatic ayixhomekeke kwimiba ye-coagulation egazini, ngoko iyasebenza kwigazi le-heparinized.Ngokujonga ukuvuza kolwelo lokugaya okubangelwa kukulimala kokungena, le gauze ye-hemostatic inokudlala indima ekuthinteleni umjelo wokuvuza kunye nokuthintela ulwelo lokugaya kumonakalo wesibini kumzimba.I-hemostasis efike ngexesha kunye nesebenzayo iphinda inciphise ukuphulukana nolwelo lomzimba, inciphise ukwenzeka komothuko, ikhusele ngokufanelekileyo inxeba, kwaye ithintele ukwenzakala kwakhona kwezicubu.
Ukongezelela, i-gauze ye-hemostatic ayichaphazeli ubushushu be-ambient kwaye isasebenza kwiqondo lokushisa legazi le-18.5 ° C.Ubomi beshelufu yiminyaka emi-5 kwaye akukho miqathango yokugcinwa ekhethekileyo efunekayo.Ukusebenzisa ukupakishwa okungangenwa ngamanzi okunyumba, kulula ukuyiphatha, kulula ukuyisebenzisa, imiyalelo yokufakela engeyiyo yobuchwephesha nayo inokusebenza ngokukhawuleza.Yindalo, ihlanjululwe kakhulu, ayinayo i-allergies kwimbali yokusetyenziswa, ayinayo ityhefu, i-non-carcinogenic, kunye ne-non-immunogenic.I-deep-sea chitosan efunyenwe kwi-krill enzulu yolwandle kwi-latitude ephezulu ihlanjululwa ngumlinganiselo wegolide, oneqondo le-deacetylation yegolide, umxholo wesinyithi esinzima kunye nomxholo ophantsi wothuthu.Isiphumo sesiphumo se-high-purity hemostatic particles yi-biological polysaccharides kulula ukuyicoca, akukho nto ye-turbidity, kwaye zizinto ezinokonakala.
