I-Shanghai TeamStand Corporation inguchwephesheumphakeli wensiza yezokwelaphakanye nomkhiqizi. Banikela ngemikhiqizo ehlukahlukene yekhwalithi ephezulu, kufaka phakathii-cannula ye-intravenous,scalp vein set inaliti,izinaliti zokuqoqa igazi,amasirinji alahlwayo, futhiamachweba angatshalwa. Kulesi sihloko, sizogxila ngokukhethekile ku-IV Cannula. Sizoxoxa ngezinhlobo ezahlukahlukene, izici, namasayizi atholakalayo emakethe namuhla.
Izinhlobo ze-IV Cannula
I-IV Cannulas ayimishini yezokwelapha ebalulekile esetshenziselwa ukwelashwa ngomthambo, ukumpontshelwa igazi, nokuphathwa kwezidakamizwa. Ziza ngezinhlobo ezahlukene ukuze zihambisane nezidingo ezithile zesiguli. Okuvame kakhuluizinhlobo ze-IV Cannulaszihlanganisa:
1. I-peripheral IV Cannula
I-peripheral IV cannula iwuhlobo olusetshenziswa kakhulu ezibhedlela nasemitholampilo. Ifakwa emithanjeni emincane eseceleni, ngokuvamile ezingalweni noma ezandleni. Lolu hlobo lufanele ukwelashwa kwesikhashana, njengokuvuselela uketshezi, ama-antibiotics, noma ukuphatha ubuhlungu. Kulula ukuyifaka nokuyikhipha, okuyenza ilungele ukusetshenziswa okuphuthumayo nokujwayelekile.
Izici Eziyinhloko:
- Ubude obufushane (imvamisa ngaphansi kwamayintshi angu-3)
- Isetshenziselwa ukufinyelela kwesikhashana (imvamisa ngaphansi kweviki)
- Itholakala ngamasayizi ahlukahlukene wegeji
- Okuvame ukusetshenziswa ekunakekelweni kweziguli ezilaliswa ngaphandle kanye neziguli
I-Central Line IV cannula ifakwa emthanjeni omkhulu, ngokuvamile entanyeni (i-jugular vein yangaphakathi), esifubeni (i-subclavian vein), noma i-groin (i-femoral vein). Isihloko se-catheter siphelela ku-vena cava ephakeme eduze kwenhliziyo. Imigqa ephakathi isetshenziselwa ukwelashwa kwesikhathi eside, ikakhulukazi uma uketshezi oluphezulu lwevolumu, i-chemotherapy, noma umsoco ophelele we-parenteral (TPN) iyadingeka.
Izici Eziyinhloko:
- Ukusetshenziswa isikhathi eside (amaviki kuya ezinyangeni)
- Ivumela ukuphathwa kwezidakamizwa ezicasulayo noma ezibulalayo
- Isetshenziselwa ukuqapha ingcindezi ye-venous emaphakathi
- Idinga indlela eyinyumba nokuqondiswa kwesithombe
3.Kuvaliwe Isistimu ye-Catheter ye-IV
A Isistimu ye-catheter ye-IV evaliwe, eyaziwa nangokuthi i-safety IV cannula, iklanywe ngeshubhu enwetshiwe enamathiselwe ngaphambili nezixhumi ezingenanaliti ukuze kuncishiswe ingozi yokutheleleka nokulimala kwezinaliti. Ihlinzeka ngesistimu evaliwe kusukela ekufakweni kuya ekulawuleni uketshezi, okusiza ukugcina ubunyumba kanye nokunciphisa ukungcoliswa.
Izici Eziyinhloko:
- Yehlisa ukuchayeka kwegazi kanye nezingozi zokutheleleka
- Ukuvikelwa kwenaliti okudidiyelwe
- Ithuthukisa ukuphepha kwabasebenzi bezempilo
- Ilungele izindawo ezinamazinga aphezulu okulawula ukutheleleka
I-Midline catheter iwuhlobo lwedivayisi ye-peripheral IV efakwe emthanjeni osengalweni engaphezulu futhi ithuthuke ukuze ichopho lilale ngezansi kwehlombe (lingafinyeleli emithanjeni emaphakathi). Ilungele ukwelashwa kwesikhathi esimaphakathi-ngokuvamile kusukela evikini elilodwa kuya kwamane-futhi ivame ukusetshenziswa lapho ukufinyelela kwe-IV njalo kuyadingeka kodwa umugqa ophakathi awudingeki.
Izici Eziyinhloko:
- Ubude busuka ku-3 kuye ku-8 amayintshi
- Ifakwe emithanjeni emikhulu ye-peripheral (isb, i-basilic noma i-cephalic)
- Ingozi encane yezinkinga kunemigqa emaphakathi
- Isetshenziselwa ama-antibiotics, i-hydration, nemithi ethile
Izici ze-cannulas emithanjeni
Ama-cannula afakwa emthanjeni aklanywe ngezici eziningi ukuqinisekisa ukunethezeka nokuphepha kwesiguli ngesikhathi sokwelashwa ngokufakwa emthanjeni. Ezinye izici ezibalulekile zifaka:
1. I-Catheter material: Ama-cannula afakwa emthanjeni enziwe ngezinto ezifana ne-polyurethane noma i-silicone. Lezi zinto ziyahambelana ne-biocompatible futhi zinciphisa ingozi ye-thrombosis noma ukutheleleka.
2. Idizayini yethiphu ye-catheter: Ithiphu ye-cannula ingakhomba noma iyindilinga. Iphuzu elibukhali lisetshenziswa lapho ukubhobozwa kodonga lomkhumbi kuyadingeka, kuyilapho ithiphu eliyindilinga lifanele imithambo ethambile ukuze kuncishiswe ingozi yezinkinga ezihlobene nokubhoboza.
3. Enamaphiko noma Angenamaphiko: Ama-cannula e-IV angaba namaphiko axhunywe kuhabhu ukuze kube lula ukuphatha nokuvikeleka ngesikhathi sokufakwa.
4. Imbobo yomjovo: Amanye ama-cannula afakwe emthanjeni afakwe imbobo yomjovo. Lezi zimbobo zivumela imithi eyengeziwe ukuthi ijovwe ngaphandle kokukhipha i-catheter.

I-16 Gauge: Lo sayizi usetshenziswa kakhulu e-ICU noma ezindaweni zokuhlinza. Lo sayizi omkhulu wenza izinqubo eziningi ezahlukene zenziwe, njengokuphathwa kwegazi, ukuphathwa koketshezi ngokushesha, nokunye.
18 Igeji: Lo sayizi ikuvumela ukuba wenze imisebenzi eminingi engenziwa yigeji engu-16, kodwa inkulu futhi ibuhlungu kakhulu esigulini. Okunye ukusetshenziswa okuvamile kufaka ukufaka igazi, ukusunduza uketshezi ngokushesha, njll. Lokhu ungakusebenzisa kumaProthokholi e-CT PE noma okunye ukuhlola okudinga osayizi abakhulu be-IV.
20 Igeji: Ungakwazi ukuphusha igazi ngalo sayizi uma ungakwazi ukusebenzisa igeji engu-18, kodwa ngaso sonke isikhathi hlola isimiso somqashi wakho. Lo sayizi ungcono ezigulini ezinemithambo emincane.
22 Igeji: Lo sayizi omncane ulungele uma isiguli singayidingi i-IV isikhathi eside futhi singaguli kakhulu. Ngokuvamile awukwazi ukunikeza igazi ngenxa yobukhulu balo, nokho, ezinye izimiso zesibhedlela zivumela ukusetshenziswa okungu-22 G uma kudingeka.
I-24 Gauge: Lo sayizi usetshenziselwa izifo zezingane futhi ngokuvamile usetshenziswa kuphela njengendlela yokugcina njenge-IV kubantu abadala.
Ekuphetheni
I-cannula ye-intravenous iyithuluzi lezokwelapha elibalulekile emisebenzini ehlukahlukene yomtholampilo. I-Shanghai TeamStand Corporation ingumnikezeli nomkhiqizi wemishini yezokwelapha eqeqeshiwe, ehlinzeka ngezinhlobonhlobo zekhwalithi ephezulu ye-cannula efakwa emthanjeni neminye imikhiqizo. Uma ukhetha i-IV cannula, kubalulekile ukucabangela izinhlobo ezahlukene, izici, nosayizi abakhona. Izinhlobo eziyinhloko yi-peripheral venous cannulae, ama-catheter e-venous amaphakathi, nama-midline catheter. Izici ezifana nokokusebenza kwe-catheter, idizayini yethiphu, kanye nokuba khona kwamaphiko noma izimbobo zokujova kufanele kucatshangelwe. Ukwengeza, usayizi we-cannula efakwe emthanjeni (okhonjiswe ukulinganisa imitha) uyahlukahluka kuye ngokungenelela kwezokwelapha okuqondile. Ukukhetha i-cannula efanelekile ye-intravenous yesiguli ngasinye kubalulekile ekuqinisekiseni ukwelashwa okuphephile nokusebenzayo ngokufakwa emthanjeni.
