Ubuvuzi-Icyiciro cya PTFE Ubushyuhe bwo hejuru Ubushyuhe bwo gufata - Biocompatibilité hamwe no kwirinda

Mu gukora ibikoresho byubuvuzi, ibikoresho byo kuboneza urubyaro, hamwe nibikoresho byo kubaga, PTFE ifata kaseti igira uruhare runini. Ariko iyo kaseti ihuye nabarwayi cyangwa ibidukikije bidasanzwe, ikibazo kimwe kiba icyambere: ni umutekano?

Icyiciro cyubuvuzi PTFE kaseti igomba kuba yujuje ubuziranenge bwibinyabuzima. Substrate ya PTFE ubwayo ni inert cyane, ariko ibifatika, primer coatings, hamwe nuburyo bwo gutunganya byose bigira ingaruka kumutekano rusange.

Aokai PTFE itanga kaseti-yubuvuzi PTFE kaseti yuzuye ISO 10993. Aka gatabo karimo imikorere ya biocompatibilité, ingamba zo kwirinda, hamwe n’umutekano ukomeye.

Imikorere ya Biocompatibilité - Urufatiro rwumutekano-urwego rwumutekano

1. Substrate ya PTFE - muburyo bwa biocompatible

PTFE igaragaramo ubudahangarwa bwimiti budasanzwe, ntibishobora gufata ibintu byose no kurwanya iyangirika. Mubisanzwe itanga imiti igabanya ubukana hamwe na coefficient nkeya yo guterana, igasigara ibinyabuzima byangiza umubiri hamwe namazi bitarinze kwangwa. Ihagaze muri polymers hamwe na biocompatible izwi cyane kugeza ubu.

2. Icunga rya silicone yo mu rwego rwo kwa muganga - platine-yakize

Ubuvuzi bwa silicone bwakize bwa platine burimo nta peroxide yangirika byongera umusaruro kandi birata biocompatibilité. Irakoreshwa cyane mukwambara ibikomere, ibisebe, hamwe no gutunganya ibikoresho byubuvuzi. Kubura kwa catalizaires byangiza bituma bikwiranye nigihe kirekire cyo guhura nuruhu.

3. Muri rusange imikorere yuzuye

Ibyiciro byubuvuzi byujuje ibyangombwa bya PTFE ntibitera ubukangurambaga, kurakara kuruhu, cyangwa cytotoxicitike mubushyuhe busanzwe bukora, kandi ntibisohora ibintu byangiza. Irashobora kwihanganira gusubiramo ubushyuhe bwo hejuru butarinze kwangirika kwa biocompatibilité.

Umuburo w'ingenzi: Guhitamo nabi ibifatika / primer coatings, cyangwa kongeramo inyongeramusaruro mugihe cyo gutunganya PTFE, bizabangamira cyane biocompatibilité. Kaseti zose za PTFE zanditseho 'ubushyuhe bwo hejuru ' zifite umutekano mubuvuzi - burigihe ugenzure hamwe ninyandiko.

Icyitonderwa Cyingenzi cyo gusaba

1. Kurikiza byimazeyo igipimo cyagenewe gukoreshwa

Emeza aho uhurira (uruhu rutagira ingano gusa, mucosal indirect / guhuza amaraso, cyangwa gushiramo) hamwe nigihe cyo guhura (igihe gito, kirekire, cyangwa gihoraho). Umutekano ufite agaciro iyo ukoreshejwe ibirenze ibizamini byemewe.

Aokai PTFE kaseti yubuvuzi yemewe kuruhu rudahwitse no guhura mugihe gito (amasaha 24). Kubindi bisabwa, baza uwagikoze.

2. Ntuzigere urenga imipaka irwanya ubushyuhe

PTFE yubushyuhe bwo hejuru bushyigikira ubushyuhe bwa serivisi bukomeza kugera kuri 260 ° C. Ubushyuhe burenze 300 ° C bushobora gutera PTFE kubora, kurekura imyuka yubumara cyane harimo hydrogène fluoride na perfluoroisobutylene.

Icyitonderwa kidasanzwe: Mubikoresho byubuvuzi nka laser scalpels hamwe nu mashanyarazi ya elegitoroniki, ubushyuhe bwaho burashobora kubaho. Nubwo ubushyuhe buringaniye buri mumipaka, ahantu hashyushye hashobora kurenga 300 ° C. Kora neza ukurikije ubushyuhe bwubushyuhe butangwa nuwabitanze kandi ukurikirane ubushyuhe nyabwo.

Uburyo bwa Sterilisation - Kurikiza inzira zemewe gusa

Kaseti nyinshi zo mubuvuzi zirahuza nuburyo bwinshi bwo kuboneza urubyaro, ariko buri kimwe gifite ibisabwa byihariye.

1. Umuvuduko ukabije wuzuye wuzuye (121–134 ° C)

• Bihuje: Yego (amanota menshi)

• Ukuzenguruka: iminota 15-30

• Icyitonderwa: Inzinguzingo zisubirwamo zishobora kugabanya buhoro buhoro imbaraga zifatika. Kwemeza kubara ukwezi hamwe nuwabikoze.

2. Okiside ya Ethylene (EO)

• Bihuje: Yego

• Icyifuzo gikenewe: Kora icyerekezo gihagije kugirango ukureho okiside ya kanseri ya kanseri isigaye hamwe n’ibicuruzwa byangiza uburozi (Ethylene chlorohydrin, Ethylene glycol)

• Igihe cyo guhaguruka: Mubisanzwe iminsi 7-14 ukurikije ubushyuhe nibikoresho

3. Imirasire ya gamma ray

• Bihujwe: Bike - kwitonda bidasanzwe birakenewe

• Ubuvumo bw'ingenzi:

  • Imirasire ya gamma irashobora kumena iminyururu ya PTFE, igatera embrittlement

  • Irashobora guhindura silicone ihuza ubucucike, bigatera gusiba igice

  • Umubare ntarengwa mubusanzwe ≤25 kGy (kwemeza nuwabikoze)

  • Umubare munini urashobora guhindura kaseti kandi ntigikoreshwa

Icyifuzo cya Aokai PTFE: Kubisabwa bisaba gamma sterilisation, saba amakuru yemewe yemewe. Dutanga amanota ya gamma ahamye hamwe no kwihanganira dose.

Kugenzura Umutekano wa Adhesive na Primer Coatings

Kasete zimwe zikoresha acrylic adhesive cyangwa primer coatings zirimo ibishishwa kama. Emeza urwego rufatika rwujuje ubuziranenge bwubuvuzi, nta:

• Abasigaye monomers

• Amashanyarazi (urugero, phthalates)

• Ibyuma biremereye

Ibyangombwa bisabwa:

• Amagambo asanzwe yatanzwe nuwabitanze yemeza ko BPA, latex, na phthalates idahari

• Imenyekanisha ryibikoresho

• Ibikururwa hamwe nibisohoka amakuru yikizamini

Irinde Guhuza Kuramba na Farumasi, Acide zikomeye, na Alkalis

Nubwo PTFE ifite imiti idasanzwe yo kurwanya imiti, kwibiza igihe kirekire mumashanyarazi amwe cyangwa abatwara ibiyobyabwenge bishobora gutera:

• Kubyimba

• Kunanirwa gufatira hamwe (delamination)

• Ibisigisigi byumubiri wamahanga

Igikorwa: Kora isuzumabushobozi ryimiti mugihe utegura igituba, ibikoresho byo kubikamo, cyangwa ibikoresho-byamazi.

Kugenzura Ubuso bwo Kuvura hamwe na Shedding

Mugihe cyubuvuzi busukuye cyane, kumena ibice ni impungenge zikomeye.

• Irinde gushushanya: Ntukoreshe ibikoresho bikarishye kugirango ukoreshe kaseti mbere yo kuyikoresha - gushushanya birashobora kubyara uduce no gukora ibibanza byanduye.

• Kugabanya imyanda: Mugihe ukata kaseti, koresha imikasi isukuye cyangwa imashini zikoresha. Irinde gutobora intoki.

• Kuburyo bwo gutabara: Hitamo ibicuruzwa bifunze impande zidafite umukungugu hamwe nuduce duto duto.

• Mbere yo gukora isuku: Ihanagura hejuru yumwenda utarimo linti wasizwe na alcool ya isopropyl kugirango ukureho umwanda mbere yo kubisaba.

Saba Inyandiko Yuzuye Yuzuye - Kurenga Raporo y'Ikizamini

Raporo yikizamini cya biocompatibilité yihariye ntabwo ihagije. Aokai PTFE irasaba gutegeka utanga gutanga:

Aokai PTFE itanga ibyangombwa byuzuye hamwe nubuvuzi bwo murwego rwo kwa muganga. Turashobora kandi gushyigikira ibyatanzwe byateganijwe hamwe na dosiye yubuhanga.

Incamake - Urutonde rwubuvuzi PTFE Urutonde rwo Guhitamo

Aokai PTFE itanga kaseti-yubuvuzi PTFE kaseti hamwe na ISO 10993 yuzuye hamwe nubufasha bwo kwemeza. Twandikire kubijyanye na dosiye tekinike nibisabwa by'icyitegererezo.

Iyi nyandiko ya tekiniki itangwa na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba ukeneye ibisobanuro birambuye, imanza zikoreshwa hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye birimo imyenda ya PTFE yubushyuhe bwo hejuru, imiti ya PTFE yubushyuhe bwo hejuru, imikandara ya meshi yubushyuhe bwo hejuru, imikandara ya laminator idafite umwenda, umwenda umwe wa PTFE, umwenda wa convoyeur utarwanya ubushyuhe hamwe nigitambara cya fiberglass, nyamuneka twandikire ukoresheje imiyoboro ikurikira:

• Bwana Guo: +86 18944819998

• Bwana Liu: +86 13705266308

Twubahiriza amahame yubunyamwuga nubunyangamugayo, twihaye guha abakiriya igisubizo kimwe cyibikoresho byabigenewe hamwe nibitekerezo byuzuye bya serivisi.
