Kwiteknoloji yezonyango ehamba ngokukhawuleza yanamhlanje, i-polymer material ebizwai-thermoplastic polyurethane (TPU)ithe cwaka ivusa uvukelo. Ifilimu yeTPU yeYantai Linghua New Material Co., Ltd.Iba yinto ebaluleke kakhulu kwimveliso yezixhobo zonyango eziphezulu ngenxa yokusebenza kwayo okugqwesileyo kunye nokuhambelana kwezinto eziphilayo. Ubukho bayo bukuyo yonke indawo, ukusuka kwiingxowa zokufakelwa zemveli ukuya kwizixhobo zempilo ezinxibayo.
1) Inqaku eliphambili: Kutheni ishishini lezonyango lithanda iTPU?
TPU ifilimuayisiyofilimu yeplastiki eqhelekileyo. Idibanisa i-elasticity yerabha kunye namandla eplastiki, inika ukuguquguquka okungakaze kubonwe kuyilo lwesixhobo sonyango.
-Ukugqwesa kwe-biocompatibility kunye nokhuseleko: Ibakala lezonyango i-TPU ibambelela ngokuthe ngqo kwimigangatho ye-biocompatibility efana ne-ISO 10993, iqinisekisa ukuba akukho mvakalelo okanye iimpendulo ezingenayo inetyhefu xa udibana nezicubu zomntu okanye igazi, ukunciphisa kakhulu umngcipheko wesigulane.
-Ukusebenza kakuhle komatshini: Ifilimu ye-TPU inamandla aphezulu (ngokuqhelekileyo> 30 MPa), i-elongation ephezulu kakhulu kwikhefu (> 500%), kunye nokumelana nokukrazula okugqwesileyo (> 30 kN / m), okwenza isixhobo siqine kakhulu kwaye sikwazi ukumelana nokwelula ngokuphindaphindiweyo, ukugoba, kunye nokunyanzeliswa ngaphandle komonakalo.
-Ukufuma kunye nokunyanzeliswa komoya: Iipropati ze-porous okanye i-hydrophilic yefilimu ye-TPU ivumela umphunga wamanzi ukuba udlule ngokukhululekile ngelixa uvimba amanzi angamanzi kunye neebhaktheriya. Oku kubalulekile ekunxityweni kwamanxeba kunye nempahla ekhuselayo yotyando, enokugcina ulusu lomile, ikhuthaze ukuphiliswa, kwaye iphucule intuthuzelo yabasebenzi bezonyango.
-Ukuchukumisa okugqwesileyo okuthambileyo kunye nokungafihli: Ifilimu ye-TPU inokwakheka okuthambileyo, ukubonelela ngokukhululeka kunye nokungenamthungo kumzimba womntu; Ukucaca kwayo okuphezulu kuququzelela abasebenzi bezonyango ukuba bajonge inkqubo yokufakwa okanye ukuphiliswa kwenxeba.
-I-Sterilizability: Ifilimu ye-TPU inokumelana neendlela ezahlukeneyo zokuxilisa, kubandakanywa i-ethylene oxide (EO), imisebe ye-gamma, kunye nemiqadi ye-electron, iqinisekisa ubunyumba kunye nokhuseleko lweemveliso zokugqibela.
2) Imeko yesicelo: Ukusuka “ongabonakaliyo” kugcino ukuya phambili kubukrelekrele
Ezi mpawu zeTPU ifilimuyenze ikhanye kwicandelo lezonyango:
-I-Infusion kunye nenkqubo yokuhanjiswa kweziyobisi: Njengoko i-infusion yangaphakathi nangaphandle yezinto eziphathekayo ze-high-end-infusion bags, izikhwama zesondlo, kunye neengxowa ze-peritoneal dialysis, ukuguquguquka kwe-TPU kunye nokuxhatshazwa kwe-rub kuqinisekisa ukuzinza kwesisombululo seziyobisi ngexesha lokuthutha kunye nokusetyenziswa, kunye nokucaca kwayo kuququzelela ukubonwa kwenqanaba le-liquid.
-Ukunyamekelwa kwenxeba kunye nokugqoka: Ukugqoka okutsha kwamanzi kunye nokuphefumula kunye noxinzelelo olubi lwenxeba (NPWT) iinkqubo zisebenzisa kakhulu ifilimu ye-TPU. Iyakwazi ukwahlula ngokufanelekileyo ukungcola kwangaphandle kwaye ikhuphe ukufuma kwinxeba, idale indawo efanelekileyo yokuphilisa inxeba.
-Iimveliso ezikhuselayo zotyando: ezisetyenziselwa ukuvelisa iileya eziphefumlayo kunye ne-antibacterial kwi-drapes yotyando, iigawuni zokuzihlukanisa, kunye nempahla ekhuselayo, ebonelela ngokhuseleko olubalulekileyo ngelixa kusonjululwa iindawo ezibuhlungu zeemveliso zelaphu ezingalukwanga zemveli ezixineneyo kwaye zingonwabanga.
-Izixhobo zonyango ezitsha: Ifilimu ye-TPU ibe yinto ephambili kwizixhobo zokungenelela ezifana ne-catheter yebhaluni yeziyobisi kunye nezixhobo zokuncedisa intliziyo eyenziweyo ngenxa yokuhambelana kwayo kwegazi kunye nokuguquguquka. Ukongezelela, kwizixhobo zonyango ezinxitywayo ezifana neepatches ezihlakaniphile, ifilimu ye-TPU isebenza njenge-substrate ngokuqhagamshelana ngokuthe ngqo nolusu, iqinisekisa induduzo kunye nokuthembeka kwexesha elide kweso sixhobo.
I-3) Ilitye lembombo lomgangatho: iiparitha eziphambili kunye nemigangatho yokuvavanya
Ukuqinisekisa ukuba yonke ibhetshi yefilimu ye-TPU ihlangabezana neemfuno ezingqongqo zonyango, sibhekisa kuthotho lwemigangatho yezizwe ngezizwe eyenza ilitye lembombo lomgangatho wayo:
Iipropati zoomatshini:
Amandla okuqina kunye nobude ngexesha lekhefu: Umgangatho oqhelekileyo osetyenziswayo we-ASTM D412 uqinisekisa ukuba ifilimu inamandla okwaneleyo kunye nokuqina.
Amandla okukrazula: Umgangatho oqhelekileyo osetyenziswayo we-ASTM D624 ulinganisa ukukwazi kwawo ukumelana nokusasazeka kweenyembezi.
-I-Biocompatibility: Kufuneka iphumelele i-ISO 10993 yovavanyo oluqhelekileyo, oluyimfuneko enyanzelekileyo yogunyaziso lokuthengisa isixhobo sonyango.
-Ukusebenza komqobo:
Inqanaba lokuThuthukiswa kokufuma (i-WVTR): Imigangatho efana ne-ASTM E96 ilinganisa ukufikeleleka komphunga wamanzi, kunye namaxabiso aphezulu abonisa ukugqithiswa komoya okungcono.
Iimpawu zokuthintela ulwelo: imigangatho efana ne-ASTM F1670/F1671 (esetyenziselwa ukuvavanya ukuchasana negazi lokwenziwa kunye nokungena kwentsholongwane).
-Iimpawu zomzimba:
Ubunzima: I-ASTM D2240 (Ubunzima be-Shore) busetyenziswa ngokuqhelekileyo, kwaye ibakala lezonyango i-TPU ngokuqhelekileyo phakathi kwe-60A kunye ne-90A ukugcina ukuguquguquka.
IFuture Outlook: ISahluko esitsha kuBukrelekrele kunye noPhuhliso oluZinzileyo
4) Ukukhangela phambili kwikamva, amathuba ophuhliso lweTPU ifilimukwinkalo yezonyango zibanzi kwaye zicacile:
-Ukudityaniswa okukrelekrele: Kwixesha elizayo, iifilimu ze-TPU ziya kudibaniswa ngakumbi kunye ne-microelectronics kunye ne-sensor zokuphuhlisa "iifilimu ezihlakaniphile" ezinokubeka iliso kwiiparamitha ze-physiological ezifana nesantya sentliziyo, iswekile yegazi, kunye nokwakheka kokubila ngexesha langempela, ukukhuthaza ukuphuhliswa kweyeza lomntu.
-I-TPU ye-Biodegradable: Ngokunyuka kolwazi lokukhuselwa kwendalo, uphuhliso lwezixhobo ze-TPU ezinokulawulwa ukuthotywa okanye ukufunxwa ngumzimba womntu kwi-vivo iya kuba yeyona ndlela iphambili yesizukulwana esilandelayo sezixhobo ezifakelwayo, ezifana ne-stents ye-vascular stants kunye ne-tissue zobunjineli ze-tissue.
-Ukuguqulwa komphezulu osebenzayo: Ngokunika iifilimu ze-TPU nge-antibacterial, i-anticoagulant, okanye ukukhuthaza ngokukhutheleyo amandla okukhula kweeseli ngokusebenzisa ubuchwepheshe bomhlaba, ukusetyenziswa kwayo kwi-implants ephezulu kunye nonyango olunzima lwamanxeba luya kwandiswa ngakumbi.
I-Yantai Linghua New Material Co., Ltd. ikholelwa ukuba ifilimu ye-TPU ikhulile ukusuka 'kwindawo ebambeleyo' ukuya 'kwizinto ezixhobisayo'. Indibaniselwano yayo eyodwa yokusebenza ivula imilinganiselo emitsha yokwenziwa kwezinto ezintsha zesixhobo sonyango. Ngoku sikwixesha legolide lenkqubela phambili yezonyango eqhutywa yisayensi yezinto, kwaye i-TPU ngokungathandabuzekiyo yenye yeenkwenkwezi zeli xesha. ”
