I-Anesthesia kunye nothotho lweSekethe yokuPhumla
Uhlobo lwe-non-phthalates lunokwenziwa ngokwezifiso
Iigranuli ezicacileyo, ezingenavumba
Akukho mfuduko okanye imvula
Iikhompawundi zenqanaba loqhagamshelwano lokutya kwimaski yeoksijini kunye necannula
Umhlophe, oluhlaza okhanyayo kunye nombala oqhelekileyo ziyafumaneka

I-Anesthesia kunye nesekethe yokuphefumula i-PVC compounds ibhekisela kwizinto ezikhethekileyo zePVC ezisetyenziselwa ukuveliswa kwezixhobo zonyango ezinxulumene ne-anesthesia kunye nokunakekelwa kokuphefumula.Ezi khompawundi zenzelwe ukuhlangabezana neemfuno ezithile kunye neemfuno zezi zicelo.Iikhompawundi ze-PVC ze-anesthesia zisetyenziselwa ukuveliswa kwezixhobo ezahlukeneyo ezisetyenziswa ngexesha leenkqubo zokuthomalalisa, ezinjengeemaski ze-anesthesia, iingxowa zokuphefumla, iityhubhu ze-endotracheal, kunye ne-catheters.Ezi khompawundi ziyilelwe ukuba zibe bhetyebhetye, kodwa zomelele, zivumela ukuphathwa ngokulula kunye nokuphathwa ngexesha leenkqubo.Zikwaqulunqwe ukuba zibe zi-biocompatible, ziqinisekisa ukuba azibangeli naziphi na iziphumo ezibi xa zidibana nezicubu zesigulane okanye ulwelo.Iikhompawundi ze-PVC zesekethe yokuphefumla, kwelinye icala, zisetyenziselwa ukuveliswa kwezixhobo zonyango lokuphefumla, kubandakanywa netyhubhu ye-ventilator, iimaski zeoksijini, izixhobo ze-nebulizer, kunye neevalvu zokuphefumla.Ezi khompawundi kufuneka zibe nokuguquguquka okugqwesileyo kunye nokumelana ne-kinking, njengoko zihlala ziphantsi kokugoba okuphindaphindiweyo kunye nokujija.Zikwaqulunqwe ukuba zihambelane neegesi zokuphefumula ezihanjiswayo kwaye akufanele zibe negalelo ekuchaseni okongeziweyo okanye ukuthintela ukuhamba kwegesi.Zombini i-anesthesia kunye nesekethe yokuphefumla iikhompawundi ze-PVC ziyilelwe ngokulawulwa komgangatho ongqongqo kwaye zithobela imigangatho kunye nemimiselo yoshishino lwezonyango ukuqinisekisa ukhuseleko nokusebenza.Abavelisi bathathela ingqalelo izinto ezinje nge-biocompatibility, ukuqina, ukumelana neekhemikhali kunye nezibulala-ntsholongwane, kunye nokulula kokwenziwa.Kuyafaneleka ukuba uqaphele ukuba ngelixa i-PVC isetyenziswe ngokuqhelekileyo kwezi zicelo ngenxa yeempawu zayo ezinqwenelekayo, iinkxalabo ziye zaphakanyiswa malunga neempembelelo ezinokuthi zenzeke kwimpilo kunye nokusingqongileyo ezinxulumene nokuveliswa, ukusetyenziswa kunye nokulahlwa kwezixhobo zonyango ezisekelwe kwi-PVC.Abaphandi kunye nabavelisi baphonononga ngenkuthalo ezinye izinto kunye nobuchwepheshe bokujongana nale nkxalabo.Ngokufutshane, i-anesthesia kunye nesekethe yokuphefumula i-PVC compounds zizinto ezikhethekileyo ezisetyenziselwa ukuveliswa kwezixhobo zonyango kwi-anesthesia kunye nokunyamekela kokuphefumula.Ezi khompawundi zenziwe ngononophelo ukuhlangabezana neemfuno ezithile zezicelo zazo, ziqinisekisa ukhuseleko, ukuqina, kunye nokusebenza.
