Filime ikora cyane ya TPU iyobora umurongo wibikoresho byubuvuzi bishya

Muri iki gihe iterambere ryihuse mubuhanga bwubuvuzi, ibikoresho bya polymer byitwathermoplastique polyurethane (TPU)acecetse atera impinduramatwara. Filime ya TPU yaYantai Linghua New Material Co., Ltd.irimo kuba ikintu cyingenzi mubikoresho byubuvuzi bwo mu rwego rwo hejuru kubera imikorere myiza na biocompatibilité. Kuba ihari irahari hose, kuva mumifuka ya infusion gakondo kugeza kubikoresho byubuzima byambarwa.

1) Ibyingenzi: Kuki inganda zubuvuzi zishimira TPU?
Filime ya TPUntabwo ari firime isanzwe. Ihuza ubuhanga bwa reberi n'imbaraga za plastiki, itanga ihinduka ritigeze ribaho mugushushanya ibikoresho byubuvuzi.
-Byiza biocompatibilité n'umutekano: Icyiciro cyubuvuzi TPU yubahiriza byimazeyo ibipimo biocompatibilité nka ISO 10993, ikemeza ko nta sensibilisation cyangwa reaction idafite uburozi iyo ihuye nuduce twabantu cyangwa amaraso, bikagabanya cyane ibyago byabarwayi.
-Imikorere yubukorikori buhebuje: Filime ya TPU ifite imbaraga zingana cyane (mubisanzwe> 30 MPa), kuramba cyane kuruhuka (> 500%), hamwe no kurwanya amarira meza (> 30 kN / m), bigatuma igikoresho kiramba cyane kandi gishobora kwihanganira kurambura inshuro nyinshi, kunama, no kwikuramo nta byangiritse.
-Ubushuhe n'umuyaga mwinshi: Imiterere ya hydrophilique ya hydrophilique ya firime ya TPU ituma imyuka y'amazi inyura mu bwisanzure mugihe ibuza amazi ya bagiteri na bagiteri. Ibi nibyingenzi muburyo bwo kwambara ibikomere hamwe nububasha bwo kubaga bwo kubaga, bushobora gutuma uruhu rwuma, bigatera gukira, kandi bikongera ihumure ryabakozi.
-Icyiza cyoroshye gukoraho no gukorera mu mucyo: Filime ya TPU ifite imiterere yoroshye, itanga uburyo bwiza kandi butagira umubiri bukwiranye numubiri wumuntu; Gukorera mu mucyo byorohereza abakozi b'ubuvuzi kureba uburyo bwo kwinjiza cyangwa gukira ibikomere.
-Sterilizability: Filime ya TPU irashobora kwihanganira uburyo butandukanye bwo kuboneza urubyaro, harimo okiside ya Ethylene (EO), imirasire ya gamma, hamwe nimirasire ya elegitoronike, byemeza umutekano muke nibicuruzwa byanyuma.

2) Ibisabwa: Kuva "kutagaragara" kurera kugeza imbere yubwenge
IbirangaFilime ya TPUitume imurika mubuvuzi:
-Uburyo bwo gutanga no gutanga ibiyobyabwenge: Nkibikoresho byimbere ninyuma byimifuka yohejuru yohejuru, imifuka yimirire, hamwe nudukapu twa dialyse ya peritoneyale, TPU ihindagurika kandi irwanya rubi itanga igisubizo cyibiyobyabwenge mugihe cyo gutwara no kuyikoresha, kandi gukorera mu mucyo byorohereza kureba urwego rwamazi.
-Kwitaho ibikomere no kwambara: Uburyo bushya bwo kwirinda amazi no guhumeka hamwe na sisitemu mbi yo kuvura ibikomere (NPWT) ikoresha cyane firime ya TPU. Irashobora gutandukanya neza imyanda ihumanya kandi ikirukana ubuhehere mu gikomere, bigatera ahantu heza ho gukira ibikomere.
-Ibicuruzwa bikingira indwara zo kubaga: bikoreshwa mugukora ibice bihumeka na antibacterial kubikoresho byo kubaga, amakanzu yo kwigunga, hamwe n imyenda ikingira, bitanga uburinzi bukomeye mugihe gikemura ibibazo byububabare bwibicuruzwa gakondo bidoda imyenda byuzuye kandi ntibyoroshye.
-Ibikoresho byubuvuzi bishya: Filime ya TPU yabaye ikintu cyingenzi mubikoresho byifashishwa mu gutabara nka ibiyobyabwenge bya ballon catheters hamwe nibikoresho bifasha umutima byifashishwa kubera guhuza neza kwamaraso no guhinduka. Mubyongeyeho, mubikoresho byubuvuzi byambara nkibikoresho byubwenge, firime ya TPU ikora nka substrate ihuye neza nuruhu, bigatuma ihumure nigihe kirekire cyibikoresho.
3) Ibuye rikomeza imfuruka yubuziranenge: ibipimo byingenzi nibipimo byo kugerageza
Kugirango buri cyiciro cya firime ya TPU cyujuje ibyangombwa bisabwa mubuvuzi, twerekeza ku ruhererekane rw'ibipimo mpuzamahanga bigize urufatiro rw'ubuziranenge bwarwo:
-Ibikoresho bya mashini:
Imbaraga zingana no kurambura kuruhuka: Bisanzwe bikoreshwa ASTM D412 byemeza ko film ifite imbaraga zihagije kandi byoroshye.
Imbaraga zamarira: ASTM D624 isanzwe ikoreshwa ipima ubushobozi bwayo bwo kurwanya amarira.
-Biokompatibilité: Igomba gutsinda ISO 10993 ikizamini gisanzwe, nikintu gisabwa kugirango uruhushya rwogucuruza ibikoresho byubuvuzi.
-Imikorere ya bariyeri:
Igipimo cyo kohereza amazi (WVTR): Ibipimo nka ASTM E96 bigereranya imyuka y’amazi y’amazi, hamwe n’agaciro gakomeye byerekana umwuka mwiza.
Imiterere ya barrière yamazi: ibipimo nka ASTM F1670 / F1671 (ikoreshwa mugupima kurwanya amaraso yubukorikori hamwe na virusi yinjira).
-Ibiranga umubiri:
Gukomera: ASTM D2240 (Gukomera ku nkombe) irakoreshwa cyane, kandi urwego rwubuvuzi TPU rusanzwe ruri hagati ya 60A na 90A kugirango rukomeze guhinduka.
Ibihe bizaza: Umutwe mushya mubwenge niterambere rirambye
4) Urebye imbere hazaza, ibyerekezo byiterambereFilime ya TPUmubyubuvuzi biragutse kandi birasobanutse:
-Kwishyira hamwe kwubwenge: Mugihe kizaza, firime ya TPU izahuzwa cyane na microelectronics hamwe na sensor kugirango batezimbere "firime zubwenge" zishobora gukurikirana ibipimo byimiterere nkumutima, isukari yamaraso, hamwe nibyuya byabize ibyuya mugihe nyacyo, biteza imbere iterambere ryubuvuzi bwihariye.
-Biodegradable TPU: Hamwe no kurushaho gukangurira abantu kurengera ibidukikije, iterambere ryibikoresho bya TPU rishobora kugenzurwa no guteshwa agaciro cyangwa kwinjizwa numubiri wumuntu muri vivo bizahinduka icyerekezo cyibanze cyibisekuru bizaza byibikoresho byatewe, nka stente vasculaire stent na stent engineering.
-Guhindura imikorere yimikorere: Muguha firime ya TPU hamwe na antibacterial, anticoagulant, cyangwa guteza imbere cyane ubushobozi bwo gukura kwingirabuzimafatizo hifashishijwe ikoranabuhanga ryo hejuru, ikoreshwa ryayo murwego rwohejuru no kuvura ibikomere bizakomeza kwagurwa.

Yantai Linghua New Material Co., Ltd. yizera ko filime ya TPU yavuye mu 'gusimbuza ibintu' ihinduka 'ibikoresho bitanga imbaraga'. Imikorere idasanzwe ihuza ni ugukingura ibipimo bishya byo kuvura ibikoresho byubuvuzi. Ubu turi mubihe byizahabu byiterambere ryubuvuzi biterwa nubumenyi bwibikoresho, kandi nta gushidikanya ko TPU ari imwe mu nyenyeri ziki gihe. ”
