Filimu ya TPU yogwira ntchito bwino ikutsogolera pakupanga zida zamankhwala zatsopano

Mu ukadaulo wa zamankhwala womwe ukupita patsogolo mofulumira masiku ano, chinthu chopangidwa ndi polima chotchedwapolyurethane ya thermoplastic (TPU)ikuyambitsa kusintha pang'onopang'ono. Filimu ya TPU yaMalingaliro a kampani Yantai Linghua New Material Co., Ltd.ikukhala chinthu chofunikira kwambiri popanga zipangizo zachipatala zapamwamba chifukwa cha magwiridwe ake abwino komanso kugwirizana kwake ndi zinthu zina. Imapezeka paliponse, kuyambira matumba achikhalidwe mpaka zida zamakono zogwiritsidwa ntchito pochiza matenda.

1) Mbali yaikulu: N’chifukwa chiyani makampani azachipatala amakonda TPU?
Filimu ya TPUsi filimu ya pulasitiki wamba. Imagwirizanitsa kulimba kwa rabara ndi mphamvu ya pulasitiki, zomwe zimapangitsa kuti pakhale kusinthasintha kosayerekezeka pakupanga zida zamankhwala.
-Kugwirizana bwino kwa zamoyo ndi chitetezo: TPU ya digiri ya zamankhwala imatsatira kwambiri miyezo yogwirizana ndi zamoyo monga ISO 10993, kuonetsetsa kuti palibe kukhudzidwa kapena zotsatira zoyipa zikakhudzana ndi minofu ya munthu kapena magazi, zomwe zimachepetsa kwambiri chiopsezo cha wodwalayo.
-Kugwira ntchito bwino kwambiri kwa makina: Filimu ya TPU ili ndi mphamvu yokoka kwambiri (nthawi zambiri>30 MPa), imatalika kwambiri ikasweka (>500%), komanso imakana kung'ambika bwino (>30 kN/m), zomwe zimapangitsa kuti chipangizocho chikhale cholimba kwambiri komanso chotha kupirira kutambasula, kupindika, ndi kukanikiza mobwerezabwereza popanda kuwonongeka.
-Chinyezi ndi mpweya wolowa: Kapangidwe ka TPU komwe kamalowa m'madzi kamalola nthunzi ya madzi kudutsa momasuka pamene ikutseka madzi ndi mabakiteriya. Izi ndizofunikira kwambiri pa mabala ndi zovala zoteteza opaleshoni, zomwe zingathandize kuti khungu likhale louma, kuchiritsa, komanso kulimbikitsa chitonthozo cha ogwira ntchito zachipatala.
-Kukhudza kofewa komanso kowonekera bwino: Filimu ya TPU ili ndi kapangidwe kofewa, komwe kumapereka kukwanira bwino komanso kopanda msoko m'thupi la munthu; Kuwonekera kwake kwakukulu kumathandiza ogwira ntchito zachipatala kuwona momwe mabala amaponderezedwa kapena kuchira.
-Kutha Kuthira: Filimu ya TPU imatha kupirira njira zosiyanasiyana zothira, kuphatikizapo ethylene oxide (EO), ma gamma rays, ndi ma electron beams, zomwe zimaonetsetsa kuti zinthu zomaliza zimakhala zothira komanso zotetezeka.

2) Chitsanzo cha momwe ntchito ikuyendera: Kuchokera pa udindo woteteza “wosaoneka” mpaka patsogolo pa nzeru
Makhalidwe awa aFilimu ya TPUpangitsani kuti izioneka bwino m'madokotala:
-Njira yoperekera mankhwala ndi mankhwala: Monga zinthu zamkati ndi zakunja za matumba apamwamba operekera mankhwala, matumba opatsa thanzi, ndi matumba oyeretsera m'mimba, kusinthasintha kwa TPU ndi kukana kupukuta kumaonetsetsa kuti yankho la mankhwalawo likhazikika panthawi yonyamula ndikugwiritsa ntchito, ndipo kuwonekera kwake kumathandiza kuwona kuchuluka kwa madzi.
-Kusamalira mabala ndi ma dressing: Ma dressing atsopano osalowa madzi komanso opumira komanso makina oletsa kupanikizika ndi mabala (NPWT) amagwiritsa ntchito kwambiri filimu ya TPU. Imatha kulekanitsa bwino zinthu zodetsa zakunja ndikutulutsa chinyezi kuchokera pabala, ndikupanga malo abwino ochiritsira mabala.
-Zoteteza opaleshoni: zimagwiritsidwa ntchito popanga zinthu zopumira komanso zophera mabakiteriya pamakatani ochitira opaleshoni, madiresi odzipatula, ndi zovala zoteteza, kupereka chitetezo chofunikira pamene kuthetsa ululu wa nsalu zachikhalidwe zosalukidwa zomwe zimakhala zodzaza komanso zosasangalatsa.
-Zipangizo Zachipatala Zatsopano: Filimu ya TPU yakhala gawo lofunika kwambiri pazipangizo zochiritsira monga ma catheter a balloon a mankhwala ndi zida zothandizira mtima zopangidwa chifukwa cha kugwirizana kwake bwino ndi magazi komanso kusinthasintha kwake. Kuphatikiza apo, muzipangizo zachipatala zomwe zimavalidwa monga ma smart patches, filimu ya TPU imagwira ntchito ngati gawo lolumikizana mwachindunji ndi khungu, kuonetsetsa kuti chipangizocho chikukhala chomasuka komanso chodalirika kwa nthawi yayitali.
3) Mwala wapangodya wa khalidwe: magawo ofunikira ndi miyezo yoyesera
Kuti tiwonetsetse kuti gulu lililonse la filimu ya TPU likukwaniritsa zofunikira zachipatala, tikunena za miyezo yapadziko lonse lapansi yomwe imapanga maziko a khalidwe lake:
-Makampani:
Mphamvu yokoka ndi kutalika kwake panthawi yopuma: ASTM D412 yomwe imagwiritsidwa ntchito kwambiri imatsimikizira kuti filimuyo ili ndi mphamvu zokwanira komanso kusinthasintha.
Mphamvu ya kung'ambika: ASTM D624 yomwe imagwiritsidwa ntchito kwambiri imayesa kuthekera kwake kukana kufalikira kwa kung'ambika.
-Kugwirizana kwa Zinthu: Ayenera kupasa mayeso a ISO 10993, chomwe ndi chofunikira chofunikira kuti avomerezedwe kutsatsa zida zamankhwala.
-Kugwira ntchito kotchinga:
Chiŵerengero cha Kutumiza kwa Madzi (WVTR): Miyezo monga ASTM E96 imayesa kuchuluka kwa mpweya wotuluka m'madzi, ndipo mitengo yapamwamba imasonyeza kuti mpweya umayenda bwino.
Kapangidwe ka zotchinga zamadzimadzi: miyezo monga ASTM F1670/F1671 (yogwiritsidwa ntchito poyesa kukana kulowa kwa magazi ndi kachilombo).
-Makhalidwe akuthupi:
Kulimba: ASTM D2240 (kulimba kwa gombe) imagwiritsidwa ntchito kwambiri, ndipo TPU ya digiri ya zamankhwala nthawi zambiri imakhala pakati pa 60A ndi 90A kuti ikhale yosinthasintha.
Chiyembekezo cha M'tsogolo: Mutu Watsopano mu Luntha ndi Chitukuko Chokhazikika
4) Poyang'ana patsogolo za tsogolo, chiyembekezo cha chitukuko chaFilimu ya TPUm'munda wa zamankhwala ndi omveka bwino:
-Kuphatikizana kwanzeru: M'tsogolomu, mafilimu a TPU adzaphatikizidwa kwambiri ndi ma microelectronics ndi masensa kuti apange "mafilimu anzeru" omwe amatha kuyang'anira magawo a thupi monga kugunda kwa mtima, shuga m'magazi, ndi kapangidwe ka thukuta nthawi yeniyeni, zomwe zimalimbikitsa chitukuko cha mankhwala apadera.
-TPU Yowola: Chifukwa cha kuchuluka kwa chidziwitso chokhudza kuteteza chilengedwe, kupanga zinthu za TPU zomwe zitha kulamulidwa kuti ziwonongeke kapena kuyamwa ndi thupi la munthu m'thupi la munthu kudzakhala njira yayikulu ya mbadwo wotsatira wa zipangizo zomwe zingabzalidwe, monga ma stenti a mitsempha yamagazi omwe amatha kuyamwa ndi ma stenti opangira minofu.
-Kusintha kwa ntchito ya pamwamba: Mwa kupatsa mafilimu a TPU okhala ndi mabakiteriya, anticoagulant, kapena kulimbikitsa kukula kwa maselo kudzera muukadaulo wa pamwamba, kugwiritsidwa ntchito kwake mu ma implants apamwamba komanso chithandizo cha mabala ovuta kudzakulitsidwa kwambiri.

Yantai Linghua New Material Co., Ltd. ikukhulupirira kuti filimu ya TPU yakula kuchoka pa 'zinthu zosinthira' kukhala 'zinthu zopatsa mphamvu'. Kuphatikiza kwake kwapadera kwa magwiridwe antchito kukutsegula magawo atsopano a zatsopano pazipangizo zachipatala. Pakadali pano tili mu nthawi yagolide ya kupita patsogolo kwa zamankhwala koyendetsedwa ndi sayansi yazinthu, ndipo mosakayikira TPU ndi imodzi mwa nyenyezi za nthawi ino.
