Muhupenyu, zvinowanzoitika kuti ruoko rwakachekwa netsaona uye ropa harisi kumira. Mumwe mukomana muduku akakwanisa kumisa kubuda ropa pashure pemasekondi mashomanene nebetsero yejesu idzva rokumisa kubuda ropa. Zvinoshamisa chaizvo here?
Iyo novel chitosan arterial hemostatic gauze inomira kubuda ropa ipapo
Ropa ndiro tsime roupenyu, uye kurasikirwa neropa rakawandisa ndicho chikonzero chikuru cherufu kubva mukukuvadzwa netsaona. Munyika yose, vanhu vanosvika mamiriyoni 1,9 vanofa gore negore nokurasikirwa neropa rakawanda. “Kana munhu achirema makirogiramu 70, huwandu hweropa remuviri hunosvika chikamu chinosvika 7% chehuremu hwemuviri, kureva 4,900 ml, kana kurasikirwa kweropa kuchipfuura 1 000 ml nekuda kwekukuvadzwa netsaona, zvine njodzi kuupenyu. Asi apo betsero yezvokurapa inosvika, yamuro yokutanga yakarovedzeka ndeyokuvhara chironda namatauro, zvipfeko, zvichingodaro, izvo zvinogona kushanda apo tsinga kana kuti capillary kubuda ropa, asi kana tsinga ichibuda ropa, miitiro yakadaro yehemostatic inowanzova isina kukwana.”
Mukurapwa kwechimbichimbi kwepamberi pechipatara, kudzora kunoshanda kwekubuda ropa kwevarwere panguva yekutanga ndiyo kiyi yekuwana nguva yekurapa uye kuponesa hupenyu.
Munguva pfupi yapfuura, itsva chitosan arterial hemostatic gauze itsva yave yakakurumbira pamusika. Iyi gauze ine yakasarudzika chitosan particle.Chitosan granules inosungirirwa kune yakakwirira-density gauze iyo inobvumira kukurumidza kurongedza uye kuomerera kukuru kune yakapoteredza tishu. Chitosan granules inonamira kune yakanyorova tishu muronda, ichivandudza gauze's tamponade effect uye kudzora kurasikirwa kweropa.
Yakasarudzika hemostatic process
Inotora mvura kubva muropa uye inogadzira gel rinobatanidza masero matsvuku eropa kuti rigadzire ropa. , kwemaminitsi mashanu. Munguva iyi, ropa richazadza bhandiji, chitosan granules inoshandiswa, inoputika uye inoshanduka kuva gel gobvu. Mushonga wejeri unovhara mudziyo unobuda ropa, womisa kubuda ropa, uye wogadzira gel kuti rivhare ronda. Panguva imwecheteyo, chitosan inosunga nemasero matsvuku eropa kuti ibudise gels, iyo inogonawo kudzivirira zvinobudirira kusvibiswa kwechipiri kwebhakitiriya kweronda.
Iyi hemostatic gauze inogona kukurumidza kudzora kubuda ropa kuri pakati nepakati uye kwakanyanya kunokonzerwa nekushungurudzika, kusanganisira kudzora kunoshanda kwekubuda ropa kwetsinga mukati memaminitsi matatu, uye haizobudisi kupisa kupisa. Pamusoro pekukodzera kubuda ropa kwakadzika, inogona zvakare kushandiswa kune maronda epamusoro. Nzvimbo yeronda haina kukwana, uye musoro, mutsipa, chifuva, dumbu uye dzimwe nhengo dzomuviri zvinogona kushandiswa zvakachengeteka. Iyo hemostatic gauze inonamira zvakasimba paronda, ichideredza njodzi yehutachiona hweropa, uye inoramba iripo apo munhu anenge abatwa achitakurwa, kudzivirira kubuda ropa kechipiri. Magwamba eropa anogona kugwamba mukati memaminitsi ekudururwa muronda, uye jira racho riri nyore kubvisa uye rinogona kugezwa nyore nyore nemvura kana nesaline. Iyo nzira yekuita kweiyo hemostatic gauze haina kutsamira pane coagulation zvinhu muropa, saka inoshanda kune heparinized ropa. Tichifunga nezvekubuda kwemvura yekugaya kunokonzerwa nekukuvara kwekupinda, iyi hemostatic gauze inogona kuita basa mukuvhara chiteshi chekudonha uye kudzivirira kugaya kwemvura kubva mukukuvara kwechipiri kumuviri. Panguva uye inoshanda hemostasis zvakare inoderedza kurasikirwa kwemvura yemuviri, inoderedza kuitika kwekuvhunduka, inochengetedza ronda, uye inodzivirira kukuvara zvakare kwetishu.
Mukuwedzera, iyo hemostatic gauze haina kukanganiswa neambient tembiricha uye ichiri kushanda pakudziya kweropa kwe18.5 ° C. Hupenyu hwesherufu makore mashanu uye hapana akakosha ekuchengetedza mamiriro anodiwa. Kushandisa sterile waterproof packaging, nyore kutakura, nyore kushanda, isiri-nyanzvi yekuisa mirayiridzo inogonawo kukurumidza kushanda. Izvo zvakasikwa, zvakacheneswa zvakanyanya, hazvina allergic reaction munhoroondo yekushandiswa, haina chepfu, isiri-carcinogenic, uye isiri-immunogenic. Iyo yakadzika-gungwa chitosan inowanikwa kubva pakadzika-gungwa krill pahupamhi hwepamusoro inocheneswa nechiyero chegoridhe, iyo ine deacetylation degree yegoridhe, yakaderera heavy metal content uye yakaderera madota. Izvo zvinokonzerwa nepamusoro-kuchena hemostatic particles ndeye biological polysaccharides iri nyore kuchenesa, hapana turbidity phenomenon, uye zvinhu zvinoparara.
