Mīkini extrusion Jwell: Nā waiwai huahana TPU papa lapaʻau a me nā noi

TPUHoʻohana nui ʻia ma ke kahua biomedical ma muli o kona biocompatibility maikaʻi loa a me nā waiwai mechanical. Ua lilo kona hoʻohana ʻana ma ke kahua lapaʻau i ʻokoʻa, me nā huahana nui e like me nā mea kōkua puʻuwai artificial, nā kīʻaha koko artificial a me ka ʻili artificial. Hoʻohana nui ʻia ka TPU lapaʻau ma ke kahua lapaʻau ma muli o kona maʻalahi, ke kūpaʻa ʻana i ka ʻaʻahu, ke kūlike kiʻekiʻe, ʻaʻohe deformation, ʻaʻohe hopena allergic, kūlike koko maikaʻi a ʻaʻole ia e hoʻopilikia i ke ʻano o ke koko.

Me ka holomua a me ka hoʻomohala ʻana o ke kaiāulu, nā mea polymer i hōʻike ʻia ePVCa ua lilo ʻo TPU i nā mea biomedical i hoʻohana nui ʻia, ʻoiai ke lilo nei ka hoʻohana ʻana i nā mea polymer i nā mea hana diagnostic in-vitro i mea nui loa.

Mea kōkua puʻuwai hana

He koʻikoʻi loa nā koi o ka mea kōkua puʻuwai hana no kona mau waiwai a me nā mea i hoʻohana ʻia no ka hana ʻana, ma muli o kona wahi koʻikoʻi, ʻaʻole e hōʻino i nā ʻāpana o ke koko, ʻaʻole e hana i nā mea ʻawahia a i ʻole nā ​​hopena alerika, ʻaʻole e hoʻoulu i nā hopena pale ʻino, ʻaʻole e hoʻokuʻu i nā electrolytes a ʻaʻole e hōʻino i nā ʻiʻo e pili ana. Hōʻike mai nā hoʻokolohua lapaʻau iā mākou he nui nā pono hana o TPU ma mua o ka rubber kūlohelohe a me ka silicone, e like me ke kūlike o ke koko a me ka lōʻihi.

Nā catheters lapaʻau

Hoʻohana pinepine ʻia ʻo TPU no ka hoʻomākaukau ʻana i nā catheters lapaʻau, e like me nā paipu infusion a me nā catheters artificial, ma muli o kona kūpaʻa mechanical, biocompatibility a me ka elasticity. ʻO ka paipu gastroscope, kahi ʻāpana koʻikoʻi o kahi gastroscope fiber optical, pono e palupalu a pliable a ʻaʻohe ʻawahia, me ke anawaena like a ʻaʻohe kūlou a hoʻopilikia paha. Hoʻokō ka paipu gastroscopy TPU i kēia mau koi a me nā koi lapaʻau.

He māmā a maʻalahi hoʻi ka paipu tracheal TPU, maʻalahi e hoʻohana ma ke ʻano lapaʻau, ʻoluʻolu no ka mea maʻi e neʻe a puni, pale i ka hōʻino ʻana o ka radiation i ke kino o ke kanaka, hoʻomaʻamaʻa i ka mālama ʻana a me ka ʻike ʻana, hiki ke pani i ka paipu tracheal metala a ʻo ia kekahi o nā mea lapaʻau holomua loa o ka honua.

Nā kiʻiʻoniʻoni lapaʻau

ʻO ka pono o nā kiʻiʻoniʻoni PE a me PVC kuʻuna he pale wai a kūpaʻa i ka wai e puka mai ana. He mea kaulana loa lākou no ka pale ʻana i nā maʻi e like me nā ʻaʻahu ʻeha a me nā hana ʻoki kino, akā he hemahema kona ʻaʻole hiki ke hoʻokahe i ka hou i hana ʻia e ka metabolism o ke kino i ka manawa kūpono, e alakaʻi ana i ka ʻoluʻolu ʻole e like me ka wela, ke anu a me ka pulu. No laila, aia kahi pono wikiwiki no kahi ʻano kiʻiʻoniʻoni lapaʻau hou e pani i ia mau huahana.

Hana ʻia nā kiʻiʻoniʻoni lapaʻau elastomer polyurethane ma ke kāpī ʻana i nā mea hoʻopili koʻikoʻi ma luna o ka ʻili o nā kiʻiʻoniʻoni elastomer polyurethane. Ke hoʻohālikelike ʻia me nā kiʻiʻoniʻoni lapaʻau PE a me PVC kuʻuna, he māmā a palupalu nā kiʻiʻoniʻoni lapaʻau kino TPU, he pilina maikaʻi ko lākou i ka ʻili, he elastic loa, he permeable ka wai a he 100% wai ʻole, kahi e pale pono ai i ka hāʻule ʻana o ke kiʻiʻoniʻoni i ka wā o ke ʻoki ʻana. Kāohi ia i ka hoʻoili ʻana o nā ʻano germs like ʻole i ka wā o ke ʻoki ʻana. E like me ke ʻoki ʻana orthopedic, ka hoʻololi ʻana i ka valve puʻuwai, ke kau ʻana i ka nila intravenous, ka intubation ʻōpū a me ka thoracic, ka mālama ʻana i ke ʻoki ʻana i ka wai spinal shunt, a me nā mea ʻē aʻe, hiki ke hōʻemi nui i ka nui o ka maʻi.

Aia kekahi elastomer polyurethane lapaʻau wai ʻole a me ka antibacterial, i hana ʻia me nā mīkina lima pale lapaʻau me nā waiwai mechanical maikaʻi, pale wai a me ka hanu, hiki ke pale aku i nā bacteria Gram-positive a me nā bacteria maikaʻi ʻole.

ʻIli hana lapaʻau

Hiki ke hana ʻia nā ʻili synthetic mai ka huʻa TPU, nona ka hanu maikaʻi loa ma muli o kona mau waiwai a hoʻolalelale hoʻi i ka ulu ʻana o ka epidermis, e pale ana i ka nalowale ʻana o ka makū a me nā paʻakai inorganic ma kahi o ka ʻeha a me ka pale ʻana hoʻi i nā maʻi bacteria. Hoʻohana pinepine ʻia ka latex kūlohelohe e hana i nā mīkina lima lapaʻau, akā no kekahi poʻe hoʻohana, loaʻa paha iā lākou kahi hopena allergic i ka latex. Eia naʻe, hiki ke hoʻololi ʻia nā elastomers polyurethane i ke ʻano molekala o nā mīkina lima lapaʻau a no laila hiki ke hoʻohana ʻia ma ke ʻano he mea hou no nā mīkina lima lapaʻau ma kahi o ka latex kūlohelohe.

Ke hoʻohālikelike ʻia me ka TPU i hoʻokumu ʻia ma MDI, he nui nā pono o nā mikina lima i hana ʻia mai nā elastomers polyurethane, e like me ka emi ʻana o ka maʻalahi i ka ʻelemakule, emi ka maʻalahi i ka hoʻololi ʻana o ke kala ma hope o kekahi manawa, emi ka maʻalahi i nā hopena alerika a kokoke i ka ʻili ma mua o nā mikina lima latex kuʻuna.

Nā wahi ʻē aʻe

Ua loaʻa mua iā TPU kekahi holomua ma ke kahua lapaʻau ma Kina, e like me ka hoʻomohala holomua ʻana o nā elastomers polyurethane hoʻomanaʻo ʻano, a me nā elastomers polyurethane hoʻomanaʻo ʻano mahana o ke kino, hiki ke hoʻohana ʻia nā lole hui kiʻiʻoniʻoni polyurethane thermoplastic e hana i nā mīkina lima anti-allergic a me nā band-aids. Ma lalo o nā kūlana hopena akahai, ua hoʻomākaukau ʻia nā elastomers polyurethane lapaʻau amphoteric biodegradable.

Eia kekahi, ua hoʻokō ʻia nā hopena maikaʻi ma nā prosthetics, cartilage, membrane hoʻokaʻawale, nā sutures lapaʻau a me nā huahana hoʻolālā ʻohana.
