PTFE Tape mubikoresho byubuvuzi: Porogaramu, Ibipimo, no kubahiriza

Reba: 0 Umwanditsi: Muhinduzi wurubuga Gutangaza Igihe: 2026-05-28 Inkomoko: Urubuga

Mu byumba bikoreramo, amavuriro y amenyo, nibikoresho byubuvuzi bikora ubwiherero, PTFE ubushyuhe bwo hejuru burahari hose - ariko akenshi byihishe. Irinda inzira ya sterisizione idafatanye, amakoti ayobora inzira yo kugenda neza, ndetse ikora ishingiro ryimyanya y'amaraso yatewe.

Bitewe nubusembure bwa chimique, friction nkeya, hamwe nubushyuhe bwumuriro, PTFE nimwe muma fluoropolymers ikoreshwa cyane mubuvuzi. Ariko nigute ushobora kumenya kaseti ya PTFE ikwiriye gukoreshwa mubuvuzi? Igisubizo giterwa n'ubwoko bw'itumanaho (guhuza abarwayi bitaziguye na indirect), ibipimo ngenderwaho (FDA, ISO 10993), hamwe nibidukikije.

Aokai PTFE yatanze ibikoresho bya PTFE kubisabwa mubuvuzi kumyaka. Iyi ngingo itondekanya ibyifuzo byubuvuzi kurwego rwitumanaho, isobanura amahame ngenderwaho ngenderwaho, kandi itanga ubuyobozi bufatika bwo guhitamo.

Inzego eshatu zo gusaba ubuvuzi kurwego rwitumanaho

Icyiciro	Ibisanzwe bya PTFE	Ibisabwa
Ibyingenzi byubuvuzi (itumanaho ritaziguye / ritaziguye)	Urushinge rwo kudoda (coating-friction); catheter / kuyobora umurongo wo kuvura; kwambara ibikomere (kudashyigikira inyuma); imitsi y'amaraso hamwe n'indwara z'umutima (e-PTFE); amenyo yumuti wamenyo	Biocompatibilité (ISO 10993), ituze ryimiti, ubukangurambaga buke, guhuza amaraso
Gukora ibikoresho byubuvuzi & gutunganya	Autoclave tray hamwe no kurinda ibyumba; gupakira ubushyuhe-bipfunyika (udupfunyika twa bliste, imifuka ya IV); igikoresho cyo kubaga ibikoresho; ibikoresho by'amashanyarazi	Kurwanya ubushyuhe bwinshi (≥260 ° C kuri cycle sterisizione), kurwanya ruswa yangiza, gusukura byoroshye, bitari inkoni
Laboratoire & kurinda rusange inganda	Isesengura ryimiti irinda hejuru; abaministri bashinzwe umutekano; ibikoresho byo kwa muganga bifunga kashe; umuyoboro wo kurwanya ruswa	Kurwanya imiti, gukora kashe, imikorere yo gukingira

Porogaramu Nkuru Yubuvuzi (Directeur / Indirect Patient Contact)

Ibinyabuzima bya PTFE byashyizweho mu myaka mirongo ikoreshwa mu mavuriro. PTFE yakiriye FDA ibyemezo byimikorere y'amaraso mu myaka ya za 1960 -, kandi yagura PTFE (e-PTFE) imaze kuba ibikoresho bisanzwe kubikoresho byatewe.

Gusaba	Gukoresha Byihariye	Umutungo wingenzi wa PTFE
Kubaga	Gupfundikanya gake ku nshinge za suture bituma ingirabuzimafatizo zinjira neza	Coefficient yo hasi cyane
Catheter & guidewire coating	Ipitingi ya PTFE igabanya ubushyamirane hagati yubuyobozi nu rukuta rwubwato, byongera kugendagenda binyuze muri anatomiya	Ingufu zo hasi zihoraho; nta hydration ikenewe kugirango amavuta
Kwambara ibikomere	Kudahumeka guhumeka birinda gukomeretsa kwa kabiri mugihe cyo guhindura imyambarire	Ingufu zo hasi, ikirere cyinjira
Imitsi y'amaraso & umutima	Dimetero ntoya e-PTFE imiyoboro y'amaraso; ihuriweho na e-PTFE ibihangano byamaraso (urugero, CoreVascu) byinjira mubigeragezo byamavuriro	Biocompatibilité nziza, imiterere ya microporous structure, antithrombotic
Kuvura umuyoboro w amenyo	PTFE membrane ikoreshwa nkibikoresho byo kwigunga mumigezi	Biocompatibilité, ituze ryimiti

Ubushishozi bwibanze: Kubisabwa byatewe, PTFE ntabwo ikoreshwa nka kaseti ahubwo nkibikoresho fatizo bitunganijwe muburyo bwihariye (urugero, e-PTFE yimitsi y'amaraso, ibishishwa). Aokai PTFE itanga ibikoresho fatizo bya PTFE abakora ibikoresho nibindi bitunganya kuriyi porogaramu.

Ibikoresho byubuvuzi Gukora & Gutunganya Porogaramu

Aha niho PTFE yubushyuhe bwo hejuru ikoreshwa cyane muburyo bwa kaseti.

1. Kurinda ibikoresho bya Sterilisation

Uburyo bwo kuboneza urubyaro	Imikorere ya Tape	Imikorere
Autoclave ya parike (121-134 ° C)	Kurinda inzira n'inkuta z'icyumba; irinde gufunga kashe / gasketi	Ihangane nubushyuhe bwo hejuru
Kuringaniza EtO	Kurinda ubuso mugihe cyo guhagarika gaze	Kurwanya imiti; nta gutesha agaciro
Imirasire ya gamma	Kurinda igihe gito (dose-biterwa)	Ntarengwa - reba ingingo ibanziriza kurwanya imirasire

Kaseti ishingiye kuri PTFE ihanganira ingirabuzimafatizo zisanzwe zirimo autoclave, EtO, hamwe na sterilant nyinshi za chimique

2. Gupakira ubushyuhe

Mugupakira blisteri yubuvuzi hamwe nimirongo ya IV ifunga imifuka, kaseti ya PTFE yashyizwe kumabari ashyushya kugirango igere kashe yihuse, isukuye nta kwimura ibintu mumifuka. Amashusho ya firime ya PTFE agumana ituze rinini hamwe nubushyuhe bwumuriro hejuru ya -73 ° C kugeza 260 ° C, bikabuza kwimura polymer mugihe cyo gufunga umufuka-

3. Kubaga ibikoresho byo kubaga

Gusaba	Inyungu
Igikoresho gikoreshwa	Kurwanya kunyerera, gufata ergonomic
Kuyobora umurongo wa gari ya moshi	Kugenda neza kumurongo, kugabanuka kubyara
Gukoresha amashanyarazi kubikoresho byimbere	Imbaraga za dielectric, ituze ryumuriro

Aokai PTFE itanga kaseti ya PTFE yubushyuhe bwo hejuru kubikoresho byo gupakira mubuvuzi no kurinda sterilisation tray. Kasete zacu ziraboneka hamwe na silicone yumuvuduko ukabije, wihanganira inshuro nyinshi za autoclave zidafite ibisigisigi.

Ibipimo ngenderwaho byubuvuzi-Urwego PTFE

1. FDA 21 CFR 177.1550 - Kubahiriza Urufatiro

FDA 21 CFR 177.1550 niryo shingiro ryubuyobozi bushinzwe ibiryo n'ibiyobyabwenge muri Amerika kubuvuzi bwa fluoropolymer. Kubahiriza byemeza ko ibikoresho bya PTFE bifite umutekano kugirango bikoreshwe inshuro nyinshi guhura nibiryo - kandi mugihe cyagutse, nibisanzwe byerekana ubuvuzi bwa PTFE.

Itandukaniro ryingenzi: FDA ntabwo yemera ibikoresho bibisi; yemeza ibikoresho byubuvuzi byarangiye. Iyo utanga isoko avuga ko PTFE ari 'FDA yemerewe, ' basobanura ko ibikoresho byujuje 21 CFR 177.1550 - mubyukuri ni uburyo bwo guhuza ibiryo- Kubikoresho byubuvuzi, kwemererwa burundu biterwa nuwakoze ibikoresho byuzuye muri FDA.

2. ISO 10993 - Ikizamini cyibinyabuzima

Kubisobanuro bitaziguye byabarwayi, PTFE igomba gupimwa kuri ISO 10993:

Ikizamini	Bisanzwe	Ibipimo byo kwemerwa
Cytotoxicity	ISO 10993-5	Ubuzima bwakagari ≥ 70%-
Gukangurira	ISO 10993-10	amanota yo gukangurira ≤1
Kurakara	ISO 10993-10	Igipimo cyo kurakara ≤2
Hemocompatibilité	ISO 10993-4	Igipimo cya Hemolysis, trombose
Kwimura	ISO 10993-6	Igisubizo cyo gutwika amanota 0-4

Ibikoresho bya PTFE birageragezwa kugirango hatagira uburozi bwakagari, nta sensibilisation, kandi nta reaction yubumara bwa sisitemu iyo ihuye nuduce twabantu.

Incamake & Guhitamo Igitabo

Niba gusaba kwawe birimo ...	Hitamo kaseti ya PTFE?	Icyitonderwa cyingenzi
Guhuza abarwayi bitaziguye (gushiramo)	Ntabwo ari kaseti - koresha ibikoresho bya PTFE bitunganijwe	Urwego rwibikoresho bya FDA bisabwa; ISO 10993 ni itegeko
Kurinda ibikoresho byo kuboneza urubyaro	Yego	Irasaba silicone PSA ihanganira inshuro nyinshi za autoclave (121-134 ° C)
Gupakira ubushyuhe	Yego	Kanda ya firime ya PTFE yatoranijwe; kugenzura ubushyuhe bwa kashe
Igikoresho cyo kubaga hejuru	Yego	Menya neza biocompatibilité ya adhesive niba abarwayi bahuye bishoboka
Kurinda ibikoresho bya laboratoire / kutarwara	Yego	Ikarita isanzwe ya PTFE irahagije

Muri make , PTFE yubushyuhe bwo hejuru itanga ibyiciro bitatu byubuvuzi. Kubikorwa byingenzi byubuvuzi (guhuza abarwayi bitaziguye), PTFE ikoreshwa nkibikoresho fatizo (ntabwo ari kaseti) byemewe kurwego rwa FDA byemewe na ISO 10993 bipimisha biocompatibilité. Kubikoresho byubuvuzi no gutunganya - kurinda ibikoresho bya sterisizione, gupakira ubushyuhe-bipfunyika, hamwe no kuvura ibikoresho - kaseti ya PTFE irashobora gukoreshwa muburyo butaziguye, hamwe na silicone PSA isabwa kubidukikije bya autoclave.

Kubahiriza amabwiriza bitangirana na FDA 21 CFR 177.1550 kubwumutekano wibikoresho, ariko kwemeza ibikoresho byanyuma bisaba kubitanga. Kubibazo bikomeye byabarwayi-bahuza, burigihe ugenzure biocompatibilité kubicuruzwa byarangiye, ntabwo ari ibikoresho bibisi gusa.

Ukeneye kaseti ya PTFE cyangwa ibikoresho fatizo kugirango usabe ubuvuzi? Aokai PTFE itanga ibicuruzwa byo mu rwego rwa PTFE. Twandikire hamwe nibisobanuro byawe bisabwa, uburyo bwo kuboneza urubyaro, nibisabwa n'amategeko.

Amakuru yavuzwe haruguru yatanzwe na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba wifuza kumenya byinshi kubyerekeranye nibisobanuro birambuye, sisitemu yo gusaba, hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye, harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, umukandara wa PTFE wo mu bushyuhe bwo hejuru, umukandara wimashini udahuza, umwenda umwe wa PTFE, umukandara wa convoyeur wihanganira ubushyuhe bwinshi hamwe nigitambara cyo hejuru cya fiberglass , nyamuneka twandikire:
