Kungani i-Silicone Catheter iyisibonelo esihle kakhulu sokusebenza ngokuphelele kubantu?

Ukungabiyo Kwemithombo Yobuhle Nezinkampani Zokusebenza Ngokwesikhathi Esincane Zokungabikho Kwezinkampani Zase-Silicone

Ukubaluleka Kwemithombo Yobuhle Ngemilayini Yezinhlobo Zokusebenza

Amakathitha e-silicone abona ukubaluleka kwabo ngokuphelele kusukela emkhoneni wokubaluleka we-siloxane—okungabiyo kuzo zonke izinkampani zokusebenza ngokwesikhathi esincane, ukugqibela kwezinkampani zokusebenza ngokwesikhathi esincane, nokugqibela kumhla wokusebenza kwezinhlobo zokusebenza kanye ne-pH yezinhlobo zokusebenza. Lokhu kukhona kungaba yindlela yokungagqibeli kwezinkampani zokusebenza ngokwesikhathi esincane kwezinhlobo zokusebenza, futhi kuyisibonelo sokubaluleka kwabo kuzo zonke izinhlobo zokusebenza.

Ukugcina Okuncane Kwemithombo Yobuhle Kwaye Ukungabiyo Kwemithombo Yobuhle Yokubhekana Nokubaluleka Kwemithombo Yobuhle

Isiphumo sesibonelo se-silicone esisemthwakathini sokugcina amaprothini siphela ngeminyaka engu-60% uma kuchazwa ngokulingana nezinye izinto ezidala kusukela ePVC noma e-latex. Ngoba inesibonelo sokugcina amanzi futhi asihlambeki, kukhona ukugcina okuncane kakhulu kwamaphlatelet. Lokhu kusho ukuthi izinyathelo zokuhlanza azizwakali kakhulu. Ngakho-ke, sizibona izikhathi ezincane kakhulu zezinkulungwane zokuhlanza zokuphuma emhlabeni. Uma isithembiso sasihlambeki kakhulu, abapatienti bafuna ukuzinikela okuncane kakhulu kwezinkinga zokuhlanza kwezindawo. Abadokotela babiza ukuthi lokhu kubiza iziphumo eziphelele uma izindlela zokusebenza ziyadingeka ukuba zibe endaweni yabo emhlabeni ngeminyaka engaphezu kwezinye ngaphandle kokuzinikela izinkinga.

Izidata zokuhlambekisa kliniki: <0.3% yezinyathelo zokuhlambeka ngqondweni nge-latex noma ne-PVC

Umphakathi wemithambo yasezinsukwini wayebonakala kakhulu ukuthi isilikoniyi yindlela eyingaphinde ibe yinkululeko yezinyawo. Amathuba okuthi abantu angaphezu kwe-0.3% baphinde baphindele kuyo, okuyisibonelo sokuphambuka ngaphezu kwamaprothukthu ase-latex apho amathuba okuthi abantu abangama-7-10% baphinde baphindele kuyo, futhi izinto zase-PVC zingama-3-5%. Kungani lokhu kwenza? Kuyinto leyo ukuthi isilikoniyi akasikhumbula lezi ziprothayini ezingaphinde zikho kuzo kwe-rubber engempela ezinokubangela ukuphindeleka kwezinyawo, futhi akusithumela amaprothukthu ayingavumelekile emzimbeni ngemuva kwezinsukwini. Kumaqondiso othi abantu abanemiphakathi yezinyawo noma abanenkinga ngemithambo yasezinsukwini kabusha, abadokotela bathi bafunde izinhlayisi zase-silikoniyi. Abantu abahlala nezinkinga zokujwayeleka kwe-spina bifida noma abaqhubeka ekuvusekeni kwemiphakathi yezinyawo kufanele baphumelele kulezi zinhlayisi ezingcono uma badinga ukuthenga imithambo yasezinsukwini ngemuva kwezinsukwini.

Ukulinganiswa kwe-ISO 10993: Isilikoniyi Siphiwa Ngokuthi Sihlanganisa Iziphakade Zokugcina Umphakathi Wemithambo Yasezinsukwini

Amathuba Amafanekayo Okuphumelela Ku-Cytotoxicity, Ukuphindeleka, Futhi Ukuthunyelwa Emzimbeni

Izicatheter zase-silicone zihamba ngokuzenzakalelayo konke izifundo ze-ISO 10993 zokugcina ukuthi ziyaphakanyiswa kwezinkambo zokuphakanyiswa kwezinyawo, ukukhanya, nokufaka emkhosini, noma isivinini esikhulu kakhulu sibonisa ukuthi isivinini sibonakala ngaphezu kwe-98%. Iziphumo zelaboratori zibonisa ukuthi lapho kusetshenziswa izinkambo zase-silicone, ukuvikela kwemithombo kushukuma ngaphezu kwe-5%, okuyisilinganiso esihle kakhulu kunalokho esibonwa ngezinkambo ezingenye ezikhona emarketini, okwenzela ukuthi kubhekwe phakathi kwe-15 kanye ne-30% yokungavikeli kwezinkambo. Umgomo walesi sivinini uyisahluko sezinhlobo zase-silicone ezizimele ekusungulweni lwabo, okungaqondwa kahle emkhosini. Lokhu kusho ukuthi akukho ukuphakanyiswa kwamazinyo amabi lapho kusetshenziswa. Ngaphezu kwalokho, abasemthwakazi besho ukuthi bafunda ukuthi kubhekwe izinkinga zokuphakanyiswa kwezinkambo zomuntu ngaphezu kwe-89% kancane kunalokho ababonayo ngezicatheter zase-latex zezintandokazi. Kulezi zindaba zokubonisa ukuthi izindlela zokubuyisela kwezicatheter zase-silicone zingabonakala njengokuzimela kakhulu kubantu abasebenza emazinkhosini.

Ukuphatha Ngokwesiqephu Se-6 Ngaphandle Kwamaphakathi Okuhambisana Nokuthuthukisa

Isilikon esemthwakaleni sezempilo sifana nesilikon esingaphansi kwe-PVC nasezirubheri ngoba lezi zinye zidinga izinkokhelo njenge-phthalates, BPA, noma izimithi ezingabi ngenyoka ukufika kwezinhlobo zokusebenza. Isilikon sifumana ukuthi kuyavuma imithwalo njenge-USP Class VI ne-ISO 10993-5 ngokwakhe kuphela, akasingaqondwa ngamakhemikhali okudibaniswa. Uma bahlola ubukhulu bezinto ozokuphuma kumateriali wakhiwa ekusebenzeni, iziphumo zibonisa okungu-0.01 mikrogamu ngomililita, okusho ukuthi akukho zinkokhelo ezindibaniswayo. Umkhawulo wakhe uyabulawa ngokuzimisa uma uqondwa ngomthwakalo wokushaya emva kweminyaka. Lokhu kusiza ekugcineni isimo nesakhiwo sesilikon esingaphansi ngaphandle kokudala izikraki ezingafani nesilikon esingaphansi. Lezi zikraki ziyabecula izihlangu zebakteria, futhi ziyabeka isibopho esikhulu emazini lapho amahlobo asebenza ngokuphelele.

Ukusebenza Kwesilikon Esingaphansi Kwemisebenzi Yokuqondwa Emazini Ngokuphelele

Izicatheter zesiSilicone ziyasebenza kahle kwezinkinga zokugcina phakathi kweminyaka apho zihlala emhlabeni ngeminyaka noma ngeminyaka eyinkulu. Le ndawo inele indawo ephambili engaqondi kuthi, okuthetha ukuthi izibonakaliso nezinkimba azizwakali kulo kakhulu kungezinye izicatheter zesiLatex noma zesiPVC. Lokhu kubiza ukuthi kunezikhathi ezincinci kuzocatheter ukuzigcina ngokungafanelekile futhi kunciphisa izifo ezihlanganiswe nezicatheter. Uma zihlala emajameni, i-silicone ihlala enele isimo sako futhi isiqinisekiso sakho, akasindisi njengamanye amathuba. Amadokotela abonile ukuthi abantu bakhuluma ngokuphelele lezicatheter nangeminyaka eyinkulu. Kulezi zinkinga zokugcina izinkimba ngeminyaka, lokhu kubalulekile ngoba ukugcina izicatheter ngeminyaka kunciphisa isivumelwano sokufa noma ukuzithanda kwezinto zokugcina.

Imibuzo Evame Ukubuzwa

Kungani izicatheter zesiSilicone zihlaziywa njengokuthi zingasindisi?

Izicatheter zesiSilicone ziyinhlanzi yezinye izinto ngoba aziphinde aqondi amaproteni apho ku-latex okuphinde kuyabangela ukuthi umuntu abe nezinkinga zokuhlukana, futhi azithwali amaproducts amabi okuhlela izinto.

Kungani izicatheter zesiSilicone zizokhala ngendlela ethile ngokuqhubekayo?

IsiSilicone sikhuluma ngokuzimisa uma sibonwa ngamaflozi wokuphila, okusiza ukukhala ngendlela ethile futhi ngokuphila ngokuphelele ngaphandle kokubhekana nokugqoka okuphinde kuyabangela ukuthi izibhakabhaka zihlale kulo lokuqhubekayo.

Yini okwenza izicatheter zesiSilicone zibe ngokulinganayo ngezinye izinto?

Umthwalo wokulinganayo wokufunda isiSilicone uyakhuluma ngokuzimisa uma kubonwa ngamaflozi wokuphila futhi ngamadokotela, okunqamuka ukuthi kuthwaliwe futhi ukukhala ngendlela ethile, okuphawula ukulinganayo.

Kungani isikhwama esingasivumeli ukuthi sikhulume ngokulinganayo kuyasebenza kanye nezicatheter?

Isikhwama esingasivumeli ukuthi sikhulume ngokulinganayo sikhuluma ukuthi akhulule amaproteni futhi amaplatelet athwaliwe, okuvumela ukuthi kubhekane ngokulinganayo kanye nokuthi kunezinkinga zokuhlukana.
