Mumazuva ano ari kukurumidza kufambira mberi tekinoroji yekurapa, chinhu chepolymer chinodanwathermoplastic polyurethane (TPU)chiri kutanga chimurenga chinyararire. Iyo TPU firimu reYantai Linghua New Material Co., Ltd.iri kuita chinhu chakakosha chakakosha mukugadzira-yekupedzisira mudziyo wekurapa nekuda kwekuita kwayo kwakanaka uye biocompatibility. Kuvepo kwayo kuri kwese kwese, kubva kumabhegi echinyakare ekuisa kune ekucheka-kumucheto anopfekeka ehutano zvishandiso.
1) Core ficha: Nei indasitiri yekurapa ichifarira TPU?
TPU firimuhaisi firimu repurasitiki rakajairwa. Inosanganisa elasticity yerabha nesimba repurasitiki, ichipa kushanduka kusati kwamboitika kune dhizaini yedhizaini yekurapa.
-Yakanaka biocompatibility uye chengetedzo: Medical giredhi TPU inoomerera kune biocompatibility zviyero se ISO 10993, kuve nechokwadi kuti hapana kunzwisiswa kana kusiri-chepfu maitiro kana wasangana nenyama yemunhu kana ropa, zvakanyanya kuderedza njodzi yemurwere.
-Kuita zvakanaka kwemuchina: TPU firimu rine simba rakanyanya kusimba (kazhinji> 30 MPa), yakanyanyisa kureba panguva yekuzorora (> 500%), uye yakanakisa kubvarura kuramba (> 30 kN/m), zvichiita kuti chiridzwa chigare chakasimba uye chikwanise kutsungirira kudzokororwa kutambanudza, kukotama, uye kudzvanywa pasina kukuvara.
-Kunyorova uye kupera kwemhepo: Iyo porous kana hydrophilic zvimiro zveTPU firimu inobvumira mhute yemvura kuti ipfuure zvakasununguka ichivharira mvura yemvura uye mabhakitiriya. Izvi zvakakosha pakupfeka maronda uye zvipfeko zvekudzivirira, izvo zvinogona kuchengetedza ganda rakaoma, kukurudzira kuporeswa, uye kuwedzera kunyaradza kwevashandi vekurapa.
-Yakanakisa kubata kwakapfava uye kujeka: TPU firimu rine yakapfava mameseji, ichipa yakasununguka uye isina musono yakakodzera kumuviri wemunhu; Kujeka kwayo kwepamusoro kunoita kuti vashandi vekurapa vatarise maitiro ekuisa kana kuporeswa kweronda.
-Sterilizability: TPU firimu rinogona kumirisana nenzira dzakasiyana siyana dzesterilization, kusanganisira ethylene oxide (EO), gamma rays, uye maerekitironi matanda, kuve nechokwadi chekushaya uye kuchengeteka kwezvigadzirwa zvekupedzisira.
2) Mamiriro ekushandisa: Kubva "asingaoneki" kuchengetedza kusvika kumberi kwehungwaru.
Aya maitiro eTPU firimuita kuti kupenye munharaunda yekurapa:
-Infusion uye chirongwa chekuendesa zvinodhaka: Seyemukati uye yekunze dhizaini mabhegi epamusoro-ekupedzisira infusion mabhegi, mabhegi ekudya, uye peritoneal dialysis mabhegi, kushanduka kweTPU uye nekukwesha kuramba kunovimbisa kugadzikana kwemushonga wemushonga panguva yekufambisa uye kushandiswa, uye kujeka kwayo kunobatsira kutarisa kwemvura.
-Kuchengetwa kwemaronda uye mapfekero: Kupfeka kutsva kwemvura uye kunofema uye neakaipa kumanikidza ronda kurapa (NPWT) masisitimu anoshandisa zvakanyanya TPU firimu. Inogona kunyatsoparadzanisa zvinosvibisa zvekunze uye kubvisa mwando kubva paronda, ichigadzira nzvimbo yakanaka yekupora maronda.
-Zvigadzirwa zvekudzivirira zvekuvhiya: zvinoshandiswa kugadzira zvinofema uye antibacterial layers yekuvhiya drapes, yekuzviparadzanisa nevamwe, uye zvipfeko zvekudzivirira, zvinopa kuchengetedzwa kwakakosha paunenge uchigadzirisa marwadzo echinyakare asiri akarukwa machira ezvigadzirwa achipfava uye kusagadzikana.
-Innovative mishonga yezvokurapa: TPU firimu rave chinhu chinokosha muzvigadzirwa zvekupindira zvakadai sezvinodhaka bharuni catheters uye yakagadzirwa nemoyo inobatsira michina nekuda kwekuenderana kwayo kweropa uye kushanduka. Uye zvakare, mumidziyo yekurapa inopfekwa senge machira akangwara, TPU firimu rinoshanda seiyo substrate yakanangana neganda, kuve nechokwadi chekunyaradza uye kuvimbika kwenguva refu kwechishandiso.
3) Ibwe rekona remhando: yakakosha paramita uye kuyedzwa zviyero
Kuti ive nechokwadi chekuti batch yega yega yeTPU firimu inosangana nezvinodiwa zvekurapa zvakaomesesa, isu tinoreva nhevedzano yezviyero zvepasi rose zvinoumba iro rekona remhando yayo:
-Mechanical properties:
Kusimba kwesimba uye kureba panguva yekuzorora: Iyo inowanzoshandiswa yakajairwa ASTM D412 inova nechokwadi chekuti firimu rine simba rakakwana uye elasticity.
Simba rekubvarura: Iyo inowanzoshandiswa yakajairwa ASTM D624 inoyera kugona kwayo kuramba kubvarura kupararira.
-Biocompatibility: Inofanirwa kupfuudza ISO 10993 yakatevedzana chiyero chekuyedza, chinova chinosungirwa chinodiwa chekurapa mudziyo wekushambadzira mvumo.
-Barrier performance:
Moisture Transmittance Rate (WVTR): Mayero akadai seASTM E96 anoyera kupfakanyika kwemhute yemvura, ine hunhu hwepamusoro hunoratidza kupinda kwemhepo kuri nani.
Liquid barrier properties: zviyero zvakadai seASTM F1670/F1671 (inoshandiswa kuyedza kuramba ropa rekugadzira uye kupinda kwehutachiona).
-Zvimiro zvemuviri:
Kuoma: ASTM D2240 (Shore hardness) inowanzoshandiswa, uye giredhi rekurapa TPU rinowanzova pakati pe60A ne90A kuchengetedza kuchinjika.
Future Outlook: Chitsauko Chitsva muhungwaru uye Sustainable Development
4) Tichitarisa mberi kune ramangwana, tarisiro yebudiriro yeTPU firimumune zvekurapa zvakafara uye zvakajeka:
-Kubatanidza kungwara: Mune ramangwana, mafirimu eTPU achave akanyatso kubatanidzwa ne microelectronics uye sensors kugadzira "mafirimu akangwara" anogona kutarisa physiological parameters senge kurova kwemoyo, shuga yeropa, uye dikita kuumbwa munguva chaiyo, kusimudzira kuvandudzwa kwemishonga yemunhu.
-Biodegradable TPU: Nekuwedzera kwekuziva kwekuchengetedzwa kwezvakatipoteredza, kuvandudzwa kwezvinhu zveTPU zvinogona kudzorwa kuti zvidzikisire kana kutorwa nemuviri wemunhu muvivo inozova iyo nhungamiro yechizvarwa chinotevera chezvishandiso zvinogoneka, senge zvinobatika vascular stents uye tishu engineering stents.
-Functional surface modification: Nekupa TPU mafirimu ane antibacterial, anticoagulant, kana kushingaira kusimudzira kukwanisa kwesero kuburikidza nepamusoro-soro tekinoroji, kushandiswa kwayo mukugadzirwa kwepamusoro-soro uye kurapwa kwemaronda kwakaoma kuchawedzerwa.
Yantai Linghua New Material Co., Ltd. anotenda kuti firimu reTPU rakura kubva 'kuchinotsiva zvinhu' kuenda ku'zvinhu zvinopa simba'. Mubatanidzwa wayo wakasarudzika wekuita uri kuvhura zviyero zvitsva zvehunyanzvi hwekurapa mudziyo. Parizvino tiri muzera regoridhe rekufambira mberi kwekurapa kunotungamirwa nesainzi yemidziyo, uye TPU pasina mubvunzo imwe yenyeredzi dzenguva ino. ”
