Foma'i-Vaega PTFE Lisi Fa'apipi'i Maualuluga-Suavai - Biocompatibility ma Fa'atonuga Puipuiga

I le gaosiga o masini fa'afoma'i, masini fa'ama'i, ma mea fa'amama fa'ama'i tipitipi, PTFE fa'apipi'i lipine ta'alo taua tele. Ae a faʻafesoʻotaʻi e le lipine tagata mamaʻi poʻo siosiomaga faʻamaʻi, e tasi le fesili e sili ona taua: pe saogalemu?

Foma'i-grade PTFE lipine e tatau ona ausia tulaga faigata biocompatibility. O le PTFE substrate lava ia e matua le aoga, ae o le pipii, faʻapipiʻi muamua, ma tulaga faʻagaioiga uma e afaina ai le saogalemu atoa.

Aokai PTFE tu'uina atu fa'afoma'i-vaega PTFE lipine fa'atasi ai ma fa'amaumauga atoa ISO 10993. O lenei ta'iala e aofia ai le fa'atinoina o le biocompatibility, puipuiga o le fa'aogaina, ma iloiloga taua mo le saogalemu.

Biocompatibility Performance - O le Faavae o le Saogalemu Fa'afoma'i-Vaega

1. PTFE substrate – fa'aletino biocompatible

O le PTFE o loʻo faʻaalia ai le faʻaogaina o vailaʻau faʻapitoa, tau le tali atu i soʻo se mea ma tetee atu i le faʻaleagaina. E masani lava ona tu'uina atu mea fa'apipi'i ma e maualalo le fe'avea'i, fa'atumauina fa'aletino e fa'asaga i a'au o le tino ma vai e aunoa ma le fa'aosoina o fa'afitiga. O lo'o fa'atulagaina i le polymers ma le biocompatibility sili ona lauiloa i le taimi nei.

2. Fomai-grade silicone pipii - platinum-faamalolo

Platinum-cured silicone silicone e leai ni peroxide decomposition byproducts ma fa'aeaina le biocompatibility sili atu. E faʻaaogaina lautele i faʻaofuofu manuʻa, paʻu maʻila, ma faʻapipiʻi masini faʻafomaʻi. O le leai o ni mea fa'aoso fa'aleaga ua talafeagai mo le fa'apa'i umi o le pa'u.

3. Aotelega atoatoa faatinoga

O le lipine PTFE fa'apitoa fa'afoma'i e fa'aosoina e leai se fa'alogona, fa'a'ono'ono o le pa'u, po'o le cytotoxicity i lalo o le vevela masani fa'agaioia, ma fa'asa'olotoina e leai ni mea mata'utia. E mafai ona tatalia le fa'amama fa'a-maualuga maualuga e aunoa ma le fa'aleagaina o lona biocompatibility.

Lapata'iga taua: Ole filifiliga le sa'o o mea fa'apipi'i/fa'apipi'i muamua, po'o le fa'aopoopoina o mea fa'aopoopo fa'aleagaina ile taimi ole fa'agaioiga o le PTFE, ole a matua fa'afefeteina ai le biocompatibility. E le o lipine PTFE uma o lo'o fa'aigoaina 'maualuga-vevela' e saogalemu fa'afoma'i – fa'amaonia i taimi uma ma fa'amaumauga.

Lapataiga Taua mo le Fa'aaogaina

1. Fa'amalieina le fa'aogaina o le lautele

Fa'amaonia le nofoaga e fa'afeso'ota'i ai (na'o le pa'u na'o, fa'afeso'ota'i le mucosal/toto, po'o le toto) ma le umi fa'afeso'ota'i (pu'upu'u, umi, po'o le fa'aalia tumau). E fa'aleaogaina le saogalēmū pe a fa'aaoga i tua atu o le fa'ata'ita'iga fa'amaonia.

Aokai PTFE lipine faʻafomaʻi faʻamaonia mo le paʻu paʻu ma fesoʻotaʻiga pupuu (≤24 itula). Mo isi talosaga, fa'afeso'ota'i le kamupani gaosi oloa.

2. Aua ne'i sili atu i tapula'a fa'atapula'aina o le vevela

PTFE maualuga-vevela lipine lagolago le vevela auaunaga faifai pea e oo atu i le 260°C . O le vevela e sili atu i le 300°C e ono fa'aoso ai le fa'aleagaina o le PTFE, fa'asa'oloto kasa oona e aofia ai le hydrogen fluoride ma le perfluoroisobutylene.

Lapata'iga fa'apitoa: I meafaigāluega fa'afoma'i e pei o scalpels laser ma iunite fa'aeletise, e mafai ona tupu fa'afuase'i le vevela fa'apitonu'u . Tusa lava pe o le averesi o le vevela o loʻo i totonu o tapulaʻa, o nofoaga vevela e mafai ona sili atu i le 300°C. Fa'agaioiga fa'atatau i tapula'a o le vevela e tu'uina atu e le fa'atau oloa ma mata'itu le vevela moni o luga.

Metotia Fa'amama - Mulimuli i Na'o Taualumaga Fa'amaonia

O le tele o lipine fa'afoma'i-va'aiga e fetaui ma le tele o metotia fa'ama'i, ae e tofu lava ma mea e mana'omia.

1. Fa'amama le ausa fa'ama'i maualuga (121–134°C)

• Fegalegaleai: Ioe (tele togi)

• Ta'amilosaga: 15-30 minute

• Manatua: O ta'amilosaga faifaipea e mafai ona fa'aitiitia le malosi o le pipii. Fa'amaonia le numera o le taamilosaga ma le fale gaosi oloa.

2. Ethylene oxide (EO) fa'ama'i

• Fegalegaleai: Ioe

• Mana'oga taua: Fa'atino ia lava le ea e fa'aumatia ai toega o le ethylene oxide ma ona mea o'ona (ethylene chlorohydrin, ethylene glycol)

• Taimi fa'alelei: E masani lava 7-14 aso fa'atatau ile vevela ma meafaitino

3. Fa'avelaina o le gamma

• Fegalegaleai: Fa'atapula'a - e mana'omia le fa'aeteete fa'apitoa

• Fa'aaliga taua:

  • Gamma irradiation e mafai ona motusia PTFE molecular filifili, mafua ai embrittlement

  • E mafai ona suia le tele o feso'ota'iga silikoni, fa'atupu ai le fa'ama'apeina o se vaega

  • Ole fua maualuga e masani lava ≤25 kGy (fa'amaonia ma le gaosiga)

  • Ole maualuga ole tui e ono fa'alili ai le lipine ma le fa'aaogaina

Aokai PTFE fautuaga: Mo talosaga e manaʻomia gamma sterilization, talosaga faʻamaumauga faʻamaonia maʻoti. Matou te ofoina atu togi gamma-maumau ma fa'amaumau fa'apalepale fua.

Fa'amaonia le Saogalemu o Fa'amau Fa'apipi'i ma Ulua'i

O nisi lipine e fa'aogaina ai le fa'apipi'i acrylic po'o le fa'apipi'i muamua o lo'o iai so'o so'o. Fa'amautu le fa'apipi'i o lo'o fetaui ma tulaga fa'afoma'i, e aunoa ma le:

• Monomer fa'a'ono'o totoe

• Fa'apalapala (fa'ata'ita'iga, phthalates)

• Metala mamafa

Fa'amaumauga mana'omia:

• Fa'amatalaga aloa'ia mai le fa'atau oloa e fa'amaonia ai le leai o se BPA, latex, ma phthalates

• Ta'utinoga o meafaitino

• Fa'amatalaga su'ega mea e mafai ona fa'aaogaina ma fa'amama

'Alo'ese Feso'ota'iga faifaipea ma vaila'au fa'ama'i, Aisa Malosi, ma Alkalis

E ui o le PTFE o loʻo faʻaalia le mataʻina o le tetee atu i vailaʻau, o le faatofu faaumiumi i nisi vailaʻau oona poʻo vailaʻau e mafai ona mafua ai:

• Fula meafaitino

• Fa'aletonu le pipii (delamination)

• Toega tino mai fafo

Fa'atino: Fa'atino su'esu'ega o le fetaui lelei i vaila'au pe a fa'ata'atia paipa, koneteina teu, po'o masini ala vai.

Puleaina Togafitiga o Laufanua ma le Fa'asa'oina o Masini

I si'osi'omaga fa'afoma'i mama, o le fa'amaligiina o fasimea ose popolega taua.

• Taofi le maosi: Aua le fa'aogaina ni meafaigaluega ma'ai e uu ai le lipine a'o le'i fa'aogaina – e mafai ona fa'atupu ni mea ninii ma fa'atupu ni nofoaga fa'aleagaina.

• Fa'aiti'itia otaota: Pe a tipiina mea fa'apipi'i, fa'aoga seleulu mama po'o tipi fa'a otometi. Aloese mai le saeia o lima.

• Mo fa'atonuga fa'alavelave: Filifili oloa e fa'amaufa'ailoga e leai se pefu ma fa'aitiitia le fa'aosoina.

• Fa'amamāina a'o le'i fa'aoga: Ta'i'ese luga i se ie e leai ni ga'o ua fa'asusu i le isopropyl alcohol e aveese ai mea leaga a'o le'i fa'aogaina.

Talosaga Fa'amaumauga o le Tausia atoatoa – I tua atu o le Lipoti o Su'ega

E le lava se lipoti o su'ega biocompatibility tuto'atasi. Ua fautuaina e Aokai PTFE le faʻatonuina o le kamupanī e tuʻuina atu:
