Niaj hnub no txoj kev kho mob sai sai, cov khoom siv polymer hu uaThermoplastic polyurethane (TPU)yog ntsiag to sparking ib kiv puag ncig. TPU zaj duab xis ntawmYantai Linghua Tshiab Khoom Co., Ltd.tau dhau los ua cov khoom tseem ceeb tseem ceeb hauv kev tsim khoom siv kho mob siab kawg vim nws qhov kev ua tau zoo thiab biocompatibility. Nws lub xub ntiag muaj nyob txhua qhov chaw, los ntawm cov hnab ntim tshuaj ib txwm siv rau cov khoom siv kho mob uas siv tau.
1) Cov yam ntxwv tseem ceeb: Vim li cas kev lag luam kho mob nyiam TPU?
TPU zaj duab xistsis yog ib zaj duab xis zoo tib yam. Nws muab cov elasticity ntawm cov roj hmab nrog lub zog ntawm cov yas, muab kev yooj yim tsis tau pom dua rau kev tsim khoom siv kho mob.
-Zoo heev biocompatibility thiab kev nyab xeeb: qib kho mob TPU nruj me ntsis raws li biocompatibility qauv xws li ISO 10993, kom tsis txhob muaj rhiab heev los yog tsis muaj tshuaj lom neeg thaum nyob rau hauv kev sib cuag nrog tib neeg cov ntaub so ntswg los yog ntshav, zoo heev txo tus neeg mob txoj kev pheej hmoo.
-Txoj kev ua haujlwm zoo heev: TPU zaj duab xis muaj lub zog tensile siab (feem ntau> 30 MPa), siab heev elongation ntawm so (> 500%), thiab kua muag zoo heev (> 30 kN / m), ua rau cov cuab yeej siv tau zoo heev thiab muaj peev xwm tiv taus ntau dua stretching, khoov, thiab compression yam tsis muaj kev puas tsuaj.
-Moisture thiab huab cua permeability: Cov ntxeem tau los yog hydrophilic zog ntawm TPU zaj duab xis tso cai rau cov dej vapor mus dawb los ntawm thaum thaiv cov dej thiab cov kab mob. Qhov no yog qhov tseem ceeb rau kev hnav khaub ncaws thiab cov khaub ncaws tiv thaiv kev phais, uas tuaj yeem ua kom tawv nqaij qhuav, txhawb kev kho mob, thiab txhim kho kev nplij siab ntawm cov neeg ua haujlwm kho mob.
-Qhov muag muag zoo heev thiab pob tshab: TPU zaj duab xis muaj qhov zoo nkauj zoo nkauj, muab kev sib haum xeeb thiab seamless rau tib neeg lub cev; Nws cov pob tshab siab ua rau cov neeg ua haujlwm kho mob saib xyuas cov txheej txheem infusion lossis kho qhov txhab.
-Sterilizability: TPU zaj duab xis tuaj yeem tiv taus ntau txoj kev ua kom tsis muaj menyuam, suav nrog ethylene oxide (EO), gamma rays, thiab cov kab hluav taws xob, ua kom tsis muaj menyuam thiab kev nyab xeeb ntawm cov khoom kawg.
2) Daim ntawv thov scenario: Los ntawm "tsis pom" kev saib xyuas mus rau pem hauv ntej ntawm kev txawj ntse
Cov yam ntxwv ntawm noTPU zaj duab xisua kom nws ci ntsa iab hauv kev kho mob:
-Infusion thiab kev xa tshuaj: Raws li cov khoom siv sab hauv thiab sab nrauv ntawm cov khoom siv high-end infusion hnab, cov hnab khoom noj khoom haus, thiab cov hnab ntim tshuaj peritoneal, TPU qhov yooj thiab rub tsis kam ua kom muaj kev ruaj ntseg ntawm cov tshuaj thaum lub sijhawm thauj mus los thiab siv, thiab nws cov pob tshab txhawb kev soj ntsuam cov kua dej.
- Kev kho mob thiab hnav khaub ncaws: Kev hnav khaub ncaws tsis zoo thiab ua pa tsis zoo thiab tsis zoo rau lub qhov txhab kho mob (NPWT) feem ntau siv TPU zaj duab xis. Nws tuaj yeem cais cov kuab paug sab nraud thiab tshem tawm cov dej noo los ntawm qhov txhab, tsim kom muaj ib qho chaw zoo rau kev kho qhov txhab.
-Cov khoom tiv thaiv kev phais: siv los tsim cov pa ua pa thiab cov kab mob tua kab mob rau cov kab mob phais, cov ris tsho sib cais, thiab cov khaub ncaws tiv thaiv, muab kev tiv thaiv tseem ceeb thaum daws qhov mob cov ntsiab lus ntawm cov khoom siv uas tsis yog-woven npuag ua rau khaus thiab tsis xis nyob.
-Cov khoom siv kho mob tshiab: TPU zaj duab xis tau dhau los ua ib qho tseem ceeb hauv cov khoom siv cuam tshuam xws li cov tshuaj zais pa catheters thiab cov khoom siv lub plawv zoo nkauj vim nws cov ntshav zoo sib xws thiab yoog raws. Tsis tas li ntawd, nyob rau hauv cov khoom siv kho mob hnav xws li ntse thaj ua rau thaj, TPU zaj duab xis ua haujlwm raws li cov substrate nyob rau hauv kev sib cuag ncaj qha rau ntawm daim tawv nqaij, ua kom muaj kev nplij siab thiab kev ntseeg ntev ntawm lub cuab yeej.
3) Lub hauv paus ntawm kev ua tau zoo: qhov tseem ceeb tsis zoo thiab cov qauv ntsuas
Txhawm rau kom ntseeg tau tias txhua pawg ntawm TPU zaj duab xis ua tau raws li cov kev cai kho mob nruj, peb xa mus rau cov txheej txheem thoob ntiaj teb uas tsim lub hauv paus ntawm nws qhov zoo:
-Mechanical zog:
Lub zog tensile thiab elongation ntawm kev tawg: Cov qauv siv feem ntau ASTM D412 ua kom cov yeeb yaj kiab muaj zog txaus thiab elasticity.
Tear lub zog: Cov qauv siv feem ntau ASTM D624 ntsuas nws lub peev xwm los tiv thaiv cov kua muag tawm.
-Biocompatibility: Yuav tsum xeem dhau ISO 10993 series tus qauv xeem, uas yog qhov yuav tsum tau ua rau kev tso cai ua lag luam khoom siv kho mob.
-Qhov kev ua tau zoo:
Moisture Transmittance Rate (WVTR): Cov qauv xws li ASTM E96 ntsuas nws cov dej vapor permeability, nrog cov nqi siab dua qhia tias huab cua permeability zoo dua.
Cov khoom ua kua dej: cov qauv xws li ASTM F1670 / F1671 (siv los ntsuas cov ntshav hluavtaws thiab cov kab mob nkag mus).
- Cov yam ntxwv ntawm lub cev:
Hardness: ASTM D2240 (Shore hardness) feem ntau yog siv, thiab qib kev kho mob TPU feem ntau yog nruab nrab ntawm 60A thiab 90A kom tswj tau yooj yim.
Yav Tom Ntej Outlook: Ib Tshooj Tshiab hauv Kev Txawj Ntse thiab Kev Txhim Kho Kom Zoo
4) Saib ua ntej rau yav tom ntej, txoj kev loj hlob zeem muag ntawmTPU zaj duab xishauv kev kho mob yog dav thiab meej:
-Kev txawj ntse kev koom ua ke: yav tom ntej, TPU cov yeeb yaj kiab yuav sib xyaw nrog microelectronics thiab sensors los tsim "cov yeeb yaj kiab ntse" uas tuaj yeem saib xyuas lub cev tsis zoo xws li lub plawv dhia, ntshav qab zib, thiab hws muaj pes tsawg leeg hauv lub sijhawm, txhawb kev txhim kho cov tshuaj kho tus kheej.
-Biodegradable TPU: Nrog rau kev paub txog kev tiv thaiv ib puag ncig, kev txhim kho ntawm TPU cov ntaub ntawv uas tuaj yeem tswj tau kom degrade lossis absorbed los ntawm tib neeg lub cev hauv vivo yuav dhau los ua cov kev taw qhia tseem ceeb ntawm cov khoom siv cog tom ntej, xws li absorbable vascular stents thiab cov ntaub so ntswg engineering stents.
-Txoj kev hloov kho qhov chaw: Los ntawm endowing TPU films nrog antibacterial, anticoagulant, los yog nquag txhawb cell loj hlob muaj peev xwm los ntawm nto technology, nws daim ntawv thov nyob rau hauv high-end implants thiab complex qhov txhab kho mob yuav nthuav ntxiv.
Yantai Linghua New Material Co., Ltd. ntseeg hais tias TPU zaj duab xis tau loj hlob los ntawm 'cov khoom siv hloov pauv' mus rau 'cov ntaub ntawv muaj zog'. Nws qhov kev ua tau zoo tshwj xeeb ua ke yog qhib qhov ntev ntawm cov cuab yeej kho mob tshiab. Peb tam sim no nyob rau hauv lub hnub nyoog kub ntawm kev kawm kho mob uas tau tsav los ntawm cov ntaub ntawv tshawb fawb, thiab TPU yog undoubtedly ib lub hnub qub ntawm lub sij hawm no. ”
