Gutegura ibisubizo by'indwara z'inkari
Chengdu Daxan Innovative Medical Tech Co., Ltd. ni ikigo cy’ibikoresho by’ubuvuzi gikorera i Chengdu cyashinzwe mu 2016. Dukoresheje ikoranabuhanga ryacu ryo gusiga irangi, twibanda ku guteza imbere irangi ry’ubuvuzi rigezweho n’ibikoresho byo gukoresha mu miyoboro y’inkari, dutanga ibisubizo byizewe kandi byoroshye byo kwita ku ndwara z’inkari. Iterambere ry’ibikoresho by’ubuvuzi rishingiye cyane ku buringanire buhambaye hagati y’ubumenyi bw’ibikoresho, guhuza ubuzima bw’umubiri n’ihumure ry’umurwayi. Mu bijyanye n’ubuvuzi bw’inkari, guhitamo ibikoresho bya catheter bigira ingaruka zikomeye ku mibereho y’umurwayi ya buri munsi, ubuzima bw’inkari bw’igihe kirekire, ndetse n’imibereho myiza y’imitekerereze muri rusange.
Catheter ya DAXAN ipakiye impapuro na plastiki ishobora gutanga PVC/TPU ibikoresho bibiri byishyurwa. Yakozwe muri polyurethane ya thermoplastic yo mu rwego rwo hejuru (TPU) y’ubuvuzi, itanga ubworoherane bwiza kandi iramba. TPU nta DEHP irimo kandi nta BPA irimo, ituma umurwayi agira umutekano binyuze mu bikoresho bihuye n’ibinyabuzima, kandi irinda ibidukikije, ifite imikorere myiza mu bidukikije ugereranyije na PVC gakondo. Kubera imiterere yayo yoroshye mu bushyuhe, TPU irakoroha iyo umubiri ushyushye, igatanga ihumure ryinshi mu gihe cyo gushyiramo catheter.
Gusobanukirwa itandukaniro rikomeye riri hagati ya catheter ya TPU ikoresha amazi n'iy'imashini ya PVC bisaba kwiga cyane ibijyanye na polimeri, ikoranabuhanga ryo gusiga irangi, n'ibisubizo by'ubuvuzi. Uko umuryango w'abaganga ku isi ugenda uhinduka ugana ku bisubizo bihamye, birambye kandi byorohereza abarwayi, impinduka kuva kuri Polyvinyl Chloride gakondo (PVC) kugera kuri Polyurethane igezweho ya Thermoplastic (TPU) igaragaza intambwe ikomeye mu buvuzi bw'inkari.
Ubumenyi bw'Imyenda Ifite Amavuta Aturuka ku Muyaga
Mbere yo kugereranya ibikoresho by'ingenzi (TPU vs. PVC), ni ngombwa gusobanukirwa imbaraga zihindura ikoranabuhanga ryo gusiga irangi rinyuze mu maziCatheter zisanzwe zidapfutse zikenera amavuta yo kwisiga hakoreshejwe udupaki twa gel dutandukanye. Iyi nzira ntabwo ari mbi gusa kandi itwara igihe kinini, ahubwo inatera ibyago byinshi byo kwinjiza bagiteri mu nzira y'inkari, bigatera indwara zandurira mu nzira y'inkari (UTIs). Byongeye kandi, gel idakwirakwira neza ishobora gutera ahantu hanini ho gucikagurika, bigatera gukomereka mu muyoboro w'inkari, inkovu, no guhagarara igihe kirekire.
Catheter ifata amazi ishyirwamo polymer yihariye—ikunze kuba Polyvinylpyrrolidone (PVP)—ifatana cyane n'uturemangingo tw'amazi. Iyo ikoreshejwe n'amazi yanduye cyangwa umuti wa saline (ukunze kuba uri mu gipfunyika), iyi pfundikizo ihinduka urwego rworoshye cyane, runyerera, kandi rusa neza. Ubu bushobozi bwo gufata amazi butuma amavuta agumaho mu buryo bwuzuye mu gihe cyose cyo gushyiramo no gukuramo amazi, bigabanya cyane ingano y'ingufu.
Kugabanya ihungabana
Imyambaro ifata amazi igabanya ubukana bw'imitsi kugeza kuri 90% ugereranije na catheters zidapfutse zirimo gel, bigabanya ibyago byo kwangirika kw'amaraso no kwangirika kw'imitsi.
Kwirinda kwandura
Mu gukuraho gukenera gukoresha gel n'intoki, uburyo bwo "kudakoraho" bworoshye, bigabanya cyane indwara za UTI zifitanye isano na catheter.
Gukoresha neza igihe
Catheter zikoreshwa mu mazi zifasha abarwayi kuzigama umwanya w'ingirakamaro, bigatuma babasha kuzishyira mu katheter vuba, mu ibanga kandi mu buryo bworoshye ahantu hose.
Kwibira mu mazi menshi: Ibikoresho bya PVC (Polyvinyl Chloride)
Mu myaka ibarirwa muri za mirongo, Polyvinyl Chloride (PVC) ni yo yari ibikoresho bisanzwe mu miyoboro y’ubuvuzi na catheter. Gukundwa kwayo biterwa n’igiciro cyayo gito, kuboneka cyane, no kuba ikora ibintu bitandukanye. Mu buryo bwayo bwa mbere, PVC ni plastiki ikomeye kandi irangirika. Kugira ngo yoroherwe bihagije kugira ngo ishyirwemo mu buvuzi, abakora bagomba kongeramo plasticizers za shimi. Plastizer ikunze gukoreshwa cyane mu mateka ni DEHP (Di(2-ethylhexyl) phthalate).
Nubwo DEHP itanga ubushobozi bwo koroshya PVC, ntabwo ihuzwa na polymer matrix. Uko igihe kigenda gihita, cyane cyane iyo ihuye n'amazi yo mu mubiri, DEHP ishobora kuva muri catheter. Iyi nzira yo kuvamo itera impungenge zikomeye ku buzima. Ubushakashatsi bwinshi mu by'ubuvuzi bwagaragaje ko DEHP itera ikibazo cy'imikorere y'imisemburo, bivuze ko ishobora kwangiza sisitemu y'imisemburo mu mubiri. Kubera iyo mpamvu, inzego zishinzwe kugenzura ku isi yose, harimo na FDA n'Ikigo cy'Uburayi gishinzwe imiti, zatanze umuburo ku bijyanye no gukoresha ibikoresho by'ubuvuzi birimo DEHP igihe kirekire, cyane cyane mu baturage batishoboye nka abagore batwite, impinja, n'abarwayi bakeneye kuvamo catheter igihe kirekire.
Byongeye kandi, PVC ifite imbogamizi ku bidukikije. Ikorwa n'itabwa rya PVC rikubiyemo shimi ya chlorine. Iyo itwitswe nk'imyanda yo kwa muganga, PVC ishobora kurekura dioxins z'uburozi bwinshi na aside hydrochloric mu kirere, bigatuma ibidukikije bihumana. Mu buryo bw'umubiri, PVC ishobora kwibasirwa cyane n'impinduka z'ubushyuhe. Irushaho gukomera mu bidukikije bikonje, bigatuma gushyiramo katheteri bitarushaho kuryoha cyangwa bikaba byanababaza umurwayi mu mezi y'itumba.
Kwibira mu mazi abira: Ibikoresho bya TPU (Polurethane ya Thermoplastic)
Polyurethane ya Thermoplastic (TPU) ihagarariye igisekuru gitaha cya polymeri zigezweho mu buvuzi. Bitandukanye na PVC, TPU irahinduka mu buryo busanzwe ku rwego rwa molekile. Igera ku buringanire bwayo butunganye bwo gukomera, kuramba, no koroha idakeneye plasticizers za shimi. Iri tandukaniro ry'ibanze ry'imiti bivuze ko TPU nta DEHP ifite 100% kandi nta BPA ifite, bikuraho burundu ibyago byo gusohora uburozi kandi biha umutekano ntarengwa w’umurwayi n’uburyo bwo guhuza umubiri.
Kimwe mu bintu bitangaje bya TPU, nk'uko bikoreshwa muri catheters nshya za DAXAN, ni uko kamere yoroshye gushyuhaIyo katheta ya TPU ifashwe bwa mbere ku bushyuhe bw'icyumba, igumana imbaraga zihagije, bigatuma byoroshye kuyishyiramo nta nkovu. Ariko, iyo imaze gushyirwa mu muyoboro w'inkari, ibikoresho bya TPU bisubiza ubushyuhe bw'umubiri busanzwe. Biroroha buhoro buhoro, bigahuza neza n'imiterere yihariye y'imitsi y'inkari z'umurwayi. Ubu buryo bwo kumva ubushyuhe bugabanya cyane umuvuduko w'imbere mu mucosa, bigabanya kubabara no kumva umubiri w'umunyamahanga, ibi bikaba ari ikibazo gikunze kugaragara mu bakoresha katheta igihe kirekire.
Byongeye kandi, TPU ifite ubushobozi bwo gukora neza cyane. Itanga imbaraga nziza zo gukurura, bivuze ko inkuta za catheter zishobora gukorwa zoroshye gato mu gihe zigumana ubuziranenge bw'imiterere yazo, bigatuma urumuri rw'imbere rurushaho kuba runini kandi inkari zigatembera vuba. Ukurikije ibidukikije, TPU ni nziza cyane ku bidukikije. Nta chlorine irimo, kandi kuyijugunya ntibituma habaho ibyuka byangiza. Kubera ko sisitemu z'ubuvuzi ku isi zishyira imbere kugura ibintu birambye, TPU igenda ihinduka ikintu gikundwa cyane n'inganda zikora ubuvuzi zishingiye ku bitekerezo byazo.
Kugereranya hagati y'impande zombi: TPU na PVC
Kugira ngo ufate icyemezo kijyanye n'ubuvuzi bw'inkari, ni ngombwa kugereranya ibi bikoresho byombi ukoresheje ibipimo by'ingenzi by'imikorere. Nubwo PVC ikomeje kuba amahitamo yorohereza ingengo y'imari, TPU iyobora mu bice bireba ubuzima bw'umurwayi, ihumure, n'inshingano ze ku bidukikije. Hasi hari ishusho yuzuye y'amakuru agereranya imiterere y'ingenzi ya Hydrophilic Intermittent TPU na PVC Catheters.
