I roto i te hangarau hauora e tere haere ana i ēnei rā, he rauemi polymer e kiia nei kopolyurethane kirihou wera (TPU)kei te whakaoho puku i tētahi hurihanga. Ko te kiriata TPU oYantai Linghua New Material Co., Ltd.Kei te noho hei rauemi matua e kore e taea te whakamahi i roto i te hanga taputapu hauora kounga teitei nā te mea he tino pai te mahi me te hototahi ki te koiora. Kei ngā wāhi katoa tōna aroaro, mai i ngā putea werohanga tuku iho ki ngā taputapu hauora hou hei mau.
1) Āhuatanga matua: He aha te take e pai ai te umanga hauora ki te TPU?
Kiriata TPUehara i te kiriata kirihou noa. Ka whakakotahi i te ngāwari o te rapa me te kaha o te kirihou, ka whakarato i te ngāwari onge mō te hoahoa taputapu hauora.
-He tino pai te hototahitanga koiora me te haumaru: Ka piri pūmau te TPU kounga hauora ki ngā paerewa hototahitanga koiora pēnei i te ISO 10993, kia kore ai e pāngia e te mate pāwera, e kore hoki e paitini ina pā ki te kiko tangata, ki te toto rānei, ka tino whakaiti i te mōrearea o te tūroro.
-He tino pai te mahi ā-mīhini: He kaha teitei te kiriata TPU (te nuinga o te wā >30 MPa), he tino roa te roa i te wā e whati ana (>500%), ā, he tino pai te ātete ki te haehae (>30 kN/m), e tino pakari ai te taputapu, ā, ka taea te tu atu ki te totoro, te piko, me te pēhitanga tonu me te kore e pakaru.
-Te makuku me te uruhanga o te hau: Mā ngā āhuatanga pūngāwerewere, wai rānei o te kiriata TPU ka taea te rere noa o te mamaoa wai, me te aukati i te wai wai me ngā huakita. He mea nui tēnei mō ngā takai patunga me ngā kākahu tiaki pokanga, ka taea te pupuri i te kiri kia maroke, te whakatairanga i te whakaora, me te whakarei ake i te whakamarie o ngā kaimahi hauora.
-He tino pai te pā ngawari me te mārama: He ngohengohe te kakano o te kiriata TPU, e whakarato ana i te pai me te uru pai ki te tinana tangata; Nā te mārama teitei ka taea e ngā kaimahi hauora te tirotiro i te tukanga werohanga, te whakaora patunga rānei.
-Te āheinga ki te whakahoromata: Ka taea e te kiriata TPU te tu atu ki ngā tikanga whakahoromata maha, tae atu ki te ethylene oxide (EO), ngā hihi gamma, me ngā hihi irahiko, kia pai ai te whakahoromata me te haumaru o ngā hua whakamutunga.
2) Te horopaki tono: Mai i te kaitiakitanga "kore e kitea" ki te mua o te matauranga
Ko ēnei āhuatanga oKiriata TPUkia tiaho i roto i te ao hauora:
-Pūnaha whaowhia me te tuku rongoā: Hei rauemi paparanga o roto, o waho hoki o ngā putea whaowhia kounga teitei, ngā putea kai, me ngā putea dialysis peritoneal, mā te ngāwari me te ātete ki te mirimiri o te TPU ka mau te pumau o te otinga rongoā i te wā e kawe ana me te whakamahi, ā, mā tōna māramatanga ka taea te tirotiro i te taumata wai.
-Te tiaki patunga me ngā takai: Ko ngā takai hou mō te wai me te manawa me ngā pūnaha whakaora patunga pēhanga kino (NPWT) e whakamahi whānuitia ana i te kiriata TPU. Ka taea e ia te wehe i ngā poke o waho me te pana i te makuku mai i te patunga, ka hanga he taiao pai mō te whakaora patunga.
-Ngā hua tiaki pokanga: e whakamahia ana hei hanga i ngā paparanga manawa me te ārai huakita mō ngā ārai pokanga, ngā kākahu wehe, me ngā kākahu tiaki, e whakarato ana i te tiakitanga nui me te whakaoti i ngā mamae o ngā hua papanga kore-whatu tuku iho he pūngāwerewere, he kore whakamarie hoki.
-Ngā taputapu hauora auaha: Kua noho te kiriata TPU hei wāhanga matua i roto i ngā taputapu wawaotanga pērā i ngā katitere poihau rongoā me ngā taputapu āwhina ngākau horihori nā te mea he pai te hototahitanga me te ngāwari o te toto. Hei tāpiri, i roto i ngā taputapu hauora ka taea te mau pērā i ngā papaki atamai, ka mahi te kiriata TPU hei papa e pā tika ana ki te kiri, e whakarite ana i te whakamarie me te pono o te taputapu mō te wā roa.
3) Te tūāpapa o te kounga: ngā tawhā matua me ngā paerewa whakamātautau
Hei whakarite kia tutuki i ia puranga kiriata TPU ngā whakaritenga hauora tino pakari, ka tirohia e mātou he raupapa paerewa o te ao e hanga ana i te tūāpapa o tōna kounga:
-Ngā āhuatanga ā-mīhini:
Te kaha kume me te roa i te whati: Mā te paerewa ASTM D412 e whakamahia whānuitia ana ka whakarite kia rawaka te kaha me te ngāwari o te kiriata.
Te kaha o te haehae: Ko te paerewa ASTM D624 e whakamahia whānuitia ana e ine ana i tōna kaha ki te ātete i te horapa o te roimata.
-Hototahi ki te Koiora: Me tutuki i te whakamātautau paerewa raupapa ISO 10993, he whakaritenga ā-ture tēnei mō te whakamanatanga hokohoko taputapu hauora.
-Te mahi ārai:
Te Reiti Tuku Makuku (WVTR): Ko ngā paerewa pēnei i te ASTM E96 e ine ana i tōna urunga ki te kohu wai, ā, ko ngā uara teitei ake e tohu ana i te urunga pai ake o te hau.
Ngā āhuatanga ārai wai: ngā paerewa pēnei i te ASTM F1670/F1671 (e whakamahia ana hei whakamātautau i te ātete ki te toto hangai me te urunga huaketo).
-Ngā āhuatanga ā-tinana:
Te pakeketanga: Ko te ASTM D2240 (te pakeketanga o te takutai) te mea e whakamahia whānuitia ana, ā, ko te TPU kounga hauora kei waenga i te 60A me te 90A hei pupuri i te ngāwari.
Te Tirohanga ki te Ao: He Upoko Hou mō te Matauranga me te Whakawhanaketanga Tauwhiro
4) Te titiro whakamua ki te heke mai, ko ngā tūmanakohanga whanaketanga oKiriata TPUi roto i te ao hauora he whānui, he mārama hoki:
-Whakaurunga atamai: I te heke mai, ka hohonu ake te whakauru o ngā kiriata TPU ki ngā hikohiko iti me ngā pūoko hei whakawhanake i ngā "kiriata atamai" ka taea te aroturuki i ngā tawhā ā-tinana pēnei i te tere o te ngakau, te huka toto, me te hanganga werawera i te wā tūturu, ka whakatairanga i te whanaketanga o te rongoā whaiaro.
-TPU pirau-koiora: I te piki haere o te mōhiotanga ki te tiaki taiao, ko te whanaketanga o ngā rauemi TPU ka taea te whakahaere kia pirau, kia mimiti rānei e te tinana tangata i roto i te tinana ora ka noho hei aronga matua o te whakatupuranga e whai ake nei o ngā taputapu whakauru, pērā i ngā stent toto mimiti me ngā stent hangarau kiko.
-Whakarerekētanga mata mahi: Mā te whakawhiwhi i ngā kiriata TPU ki ngā huakita, ki ngā ārai toto, ki te whakatairanga kaha rānei i ngā āheinga tipu pūtau mā te hangarau mata, ka whānui ake tōna whakamahinga i roto i ngā whakaurunga kounga teitei me te maimoatanga patunga uaua.
E whakapono ana a Yantai Linghua New Material Co., Ltd. kua tipu te kiriata TPU mai i te 'rauemi whakakapi' ki te 'rauemi whakamana'. Ko tana huinga mahi ahurei kei te whakatuwhera i ngā āhuatanga hou o te auahatanga taputapu hauora. Kei roto tātou i tētahi wā koura o te ahunga whakamua hauora e akiakihia ana e te pūtaiao rauemi, ā, ko TPU tētahi o ngā whetu o tēnei wā.
