M'moyo, nthawi zambiri zimachitika kuti dzanja limadulidwa mwangozi ndipo magazi sasiya.Kamnyamata kakang’ono kanatha kusiya magazi pambuyo pa masekondi angapo mothandizidwa ndi nsalu yatsopano yopyapyala kuti asiye kutuluka magazi.Kodi ndizodabwitsadi choncho?
Buku la chitosan arterial hemostatic gauze limasiya kutuluka magazi nthawi yomweyo
Magazi ndiye gwero la moyo, ndipo kutaya magazi kwambiri ndiko chifukwa chachikulu cha imfa ya ngozi yangozi.Padziko lonse, anthu 1.9 miliyoni amafa chaka chilichonse chifukwa chotaya magazi kwambiri."Ngati munthu akulemera makilogalamu 70, kuchuluka kwa magazi a thupi kumakhala pafupifupi 7% ya kulemera kwa thupi, ndiko kuti, 4,900 ml, ngati kutaya magazi kupitirira 1,000 ml chifukwa chovulala mwangozi, ndi zoopsa ku moyo."Koma chithandizo chamankhwala chikafika, chithandizo choyamba chofala ndicho kuphimba chilondacho ndi matawulo, zovala, ndi zina zotero, zomwe zingagwire ntchito pamene mtsempha kapena capillary ikutuluka, koma ngati mtsempha wamagazi ukutuluka, miyeso ya kukhetsa magazi yoteroyo kaŵirikaŵiri imakhala yosakwanira.”
Mu chithandizo chadzidzidzi chisanadze chipatala, kuwongolera moyenera magazi a odwala nthawi yoyamba ndiye chinsinsi chopezera nthawi yamankhwala ndikupulumutsa miyoyo.
Posachedwapa, chopyapyala chatsopano cha chitosan arterial hemostatic gauze chatchuka pamsika.Gauze ili ndi gawo lapadera la chitosan. Ma granules a Chitosan amamangiriridwa ku nsalu yopyapyala kwambiri yomwe imalola kulongedza mwachangu komanso kutsatira kwambiri minofu yozungulira.Ma granules a Chitosan amamatira ku minofu yonyowa pabalapo, kuwongolera mphamvu ya tamponade ya gauze ndikuwongolera kutaya magazi.
Wapadera hemostatic ndondomeko
Imayamwa madzi m'magazi ndikupanga gel osakaniza omwe amaphatikiza maselo ofiira a magazi kuti apange magazi.Kuletsa kutuluka kwa magazi 100%, ikani mosamala mbali ya bandeji ya hemostatic pabalaza, kusindikiza (tampon) ndikugwira, kukanikiza ndi manja anu. , kwa mphindi 5.Panthawi imeneyi, magazi amakhutitsa bandeji, ma granules a chitosan amatsegulidwa, kutupa ndikusintha kukhala gel osakaniza.Kuchuluka kwa gel osakaniza kumatsekereza chotengera chokhetsa magazi, kuyimitsa magazi, ndikupanga gel otsekera chilonda.Nthawi yomweyo, chitosan imamangiriza ndi maselo ofiira amwazi kuti apange ma gels, omwe amathanso kuteteza kuipitsidwa kwachiwiri kwa bakiteriya pachilonda.
Wopyapyala wa hemostatic uyu amatha kuletsa magazi pang'onopang'ono komanso owopsa chifukwa cha kuvulala, kuphatikiza kuwongolera bwino kwa magazi m'mitsempha yayikulu mkati mwa mphindi zitatu, ndipo sikutulutsa kutentha.Kuphatikiza pa kukhala oyenera kukhetsa magazi kwambiri m'mitsempha, itha kugwiritsidwanso ntchito zilonda zapamtunda.Malo a bala siwochepa, ndipo mutu, khosi, chifuwa, mimba ndi ziwalo zina za thupi zingagwiritsidwe ntchito bwinobwino.The hemostatic gauze amamatira mwamphamvu pabalalo, kuchepetsa chiopsezo cha tizilombo toyambitsa matenda opatsirana m'magazi, ndikukhalabe m'malo pamene wovulalayo akunyamulidwa, kulepheretsa kutuluka kwa magazi kachiwiri.Magazi amatha kutsekeka pakangopita mphindi zochepa kuti atsanulire pabalapo, ndipo magaziwo amakhala osavuta kuchotsa ndipo amatha kutsukidwa mosavuta ndi madzi kapena saline.Limagwirira wa zochita za hemostatic yopyapyala sizidalira coagulation zinthu mu magazi, choncho ndi ogwira heparinized magazi.Poona kutuluka kwa madzi am'mimba chifukwa cha kuvulala kolowera, gauze ya hemostatic iyi imatha kutsekereza njira yotuluka ndikuletsa madzi am'mimba kuti asawonongekenso mthupi.Hemostasis yapanthawi yake komanso yothandiza imachepetsanso kutayika kwa madzi am'thupi, imachepetsa kugwedezeka, imateteza bwino bala, komanso imapewa kuvulalanso kwa minofu.
Kuphatikiza apo, gauze wa hemostatic samakhudzidwa ndi kutentha kozungulira ndipo amagwirabe ntchito pa kutentha kwa magazi kwa 18.5 ° C.Nthawi ya alumali ndi zaka 5 ndipo palibe zofunikira zosungirako zapadera zomwe zimafunikira.Kugwiritsa ntchito zoyikapo zopanda madzi, zosavuta kunyamula, zosavuta kugwiritsa ntchito, malangizo oyika omwe si akatswiri amathanso kuyendetsedwa mwachangu.Ndi zachilengedwe, zoyeretsedwa kwambiri, sizikhala ndi zotsatira zowonongeka m'mbiri ya ntchito, ndizopanda poizoni, zopanda carcinogenic, komanso zopanda immunogenic.Chitosan chakuya chomwe chimapezedwa kuchokera ku krill yakuya kumtunda wautali chimatsukidwa ndi chiŵerengero cha golide, chomwe chili ndi digiri ya deacetylation ya golide, zitsulo zotsika kwambiri komanso phulusa lochepa.The chifukwa mkulu-kuyera hemostatic particles ndi kwachilengedwenso polysaccharides zosavuta kuyeretsa, palibe turbidity chodabwitsa, ndipo ndi degradable zipangizo.
