Pehea e hoʻohana ʻia ai ke kiʻiʻoniʻoni no ka ʻaʻahu ʻana i nā ʻeha?
Ka Hoʻohui Mea a me ka Palekana Pili ʻili
Kiʻiʻoniʻoni no ka ʻaʻahu ʻeha pono ʻole ka cytotoxic, ʻaʻole hoʻonāukiuki, a ʻaʻole hoʻi e ʻike. ʻO nā polymers kumu maʻamau ka polyurethane (PU), silicone, a me nā hui polyolefin. Hoʻolālā ʻia kēia mau mea no ka mālama ʻana i kahi ʻeha ʻeha ʻoiai e pale ana i nā mea haumia o waho. Loaʻa nā waiwai waiwai nui:
- Ka helu helu hoʻonanea o ka ʻili: ≤ 0.4 (ISO 10993-10).
- Laki hoʻonaʻauao: <1% i nā ho'āʻo paʻi hou.
- Ka hoʻomanawanui ʻana o ka dermal: E hele i ka OECD 404 i ka hoʻonāukiuki nui.
ʻO ka hanu a me ka hoʻokele wai
ʻO ka Moisture Vapor Transmission Rate (MVTR) ka palena koʻikoʻi no nā ʻaʻahu ʻeha. Pono ia e kaulike i ka hoʻokele exudate me ka pale ʻana i ka maceration. Aia ma lalo iho kahi hoʻohālikelike o nā hale kiʻiʻoniʻoni maʻamau i hoʻohana ʻia i ka mālama ʻeha:
| ʻAno Kiʻiʻoniʻoni | Mānoanoa (μm) | MVTR (g/m²/24h) @ 37°C, hoohuliia | ʻAʻole wai (Hydrostatic Head, cm H₂O) | Hoʻohana maʻamau |

Nā Metric Hana Koʻikoʻi: Tensile Strength, MVTR, and Hoʻopilikino ʻia
Pono nā kiʻiʻoniʻoni lapaʻau e kū i ka hana ʻana, ka hoʻopili ʻana, a me ka mālama ʻana i nā lāʻau lapaʻau. Aia ma lalo iho nei ka hoʻohālikelike ʻana i nā waiwai mechanical a me nā mea pale no nā māka lapaʻau like ʻole:

ʻO Hangzhou Zhongcheng Mea waiwai Technology Co., Ltd.'s Medical Film Expertise
He ʻoihana hou ʻo Hangzhou Zhongcheng Material Technology Co., Ltd. i ka noiʻi, hoʻomohala, hana a kūʻai aku i nā kiʻiʻoniʻoni plastik, me nā kiʻiʻoniʻoni olakino. Hāʻawi ka hui i nā mea kūʻai aku i nā huahana kiʻiʻoniʻoni kiʻekiʻe me ka ʻenehana kiʻekiʻe a me nā lako hana, nā ʻano hoʻokolohua hoʻokō huahana piha, a me kahi ʻōnaehana hōʻoia maikaʻi. Hana ʻia kā mākou mau kiʻiʻoniʻoni ma ka ISO Class 8 maʻemaʻe kaiapuni a hōʻoia ʻia no nā pae endotoxin ma lalo o 0.5 EU/mL.
No ke aha he mea koʻikoʻi ka paʻi kiʻiʻoniʻoni sterile?
Nā ʻano hana ʻino (EtO, Gamma, E-beam)
Hoʻopili ʻiʻo kiʻiʻoniʻoni sterile Pono ka hoʻohālikelike ʻana me ka sterilization terminal ʻoiai e mālama ana i ka pono o ka sila a me nā waiwai waiwai. Ke kau nei kēlā me kēia ʻano sterilization i nā ʻokoʻa like ʻole:
- Ethylene Oxide (EtO): Pono ka aeration e wehe i nā koena; Pono ke kiʻiʻoniʻoni e komo i ke kinoea.
- Hoʻomaʻamaʻa Gamma: Hiki ke kumu i ka ʻoki ʻana i ke kaulahao polymer a i ʻole ka hoʻopili ʻana; pono paha nā stabilizers.
- E-kukui: ʻOi aku ka wikiwiki ma mua o ka gamma akā ke komo haʻahaʻa; kūpono no nā kiʻi ʻoniʻoni lahilahi.
Hōʻoiaʻiʻo i ka ʻoiaʻiʻo o ka Sila a me ke ola
ʻO ka hōʻoia ʻana o ka hoʻopaʻa ʻana ma hope o ASTM F1929 (ka komo ʻana o ka wai) a me ASTM F88 (ikaika sila). Loaʻa nā koi maʻamau:
| ʻĀpana | Koina ʻae | ʻAno hoʻāʻo |
|---|---|---|
| Ka ikaika o ka sila (peel) | ≥ 1.5 N/15 mm | ASTM F88 |
| Ke komo ʻana o ke kala | ʻAʻole ka neʻe ʻana ma waho o ka lihi sila | ASTM F1929 |
| ʻO ka ʻelemakule (40°C/75% RH) | E hoʻopaʻa i ≥90% ikaika sila mua ma 6 mahina like | ASTM F1980 |
Hiki ke hoʻohana ʻia ke kiʻiʻoniʻoni biodegradable no ka lāʻau lapaʻau?
Nā Koho Biopolymer (PLA, PHA, Cellulose)
ʻO ka hoʻomohala ʻana o mea kino kiʻiʻoniʻoni biodegradable manaʻo e hōʻemi i ka wāwae ʻōpala lapaʻau. ʻO nā polymers o nā moho he:
- PLA (Polylactic acid): Hiki ke hoʻopili ʻia ma lalo o nā kūlana ʻoihana, akā palena ʻia ka MVTR a me ka maʻalahi.
- PHA (Polyhydroxyalkanoates): Hiki ke hoʻoheheʻe ʻia i ka moana, ʻoi aku ka maikaʻi ma mua o ka PLA.
- ʻO ka cellulose i hana hou ʻia: MVTR kiʻekiʻe, akā koi i nā plasticizers no ka maʻalahi.
Ka Manawa Hoʻohaʻahaʻa vs
ʻO kahi paʻakikī koʻikoʻi ke kaulike ʻana i ka helu degradation me ke ola paʻa pono (maʻamau 2-5 mau makahiki no nā mea lapaʻau). Aia ma lalo kahi hoʻohālikelike o ka paʻa biopolymer:
| Material | Paʻa Ola (makahiki @ 25°C/50% RH) | Hoʻomaka ka Degradation | MVTR (g/m²/24h) |
|---|---|---|---|
| PLA (amorphous) | 1-2 (pilikia hydrolysis) | 8-12 pule | 400–600 |
| PHA (PHB/HV copolymer) | 2–3 | 6-8 pule | 200–400 |
| Cellulose acetate (plasticized) | 3–5 | 12–24 pule | 600–900 |
Ke kaulike ʻana i ka hoʻomau ʻana me ka hana pale
No nā mea lapaʻau hoʻohana hoʻokahi e like me nā pale ʻokiʻoki a i ʻole nā papa pili ʻeha, ʻaʻole pono ka compostability e hoʻololi i ka palekana o ka maʻi. Ke kūkulu ʻia nei nā hale huila (e laʻa, biopolymer lahilahi i uhi ʻia i ke kiʻiʻoniʻoni maʻamau) e hoʻokō ʻia nā pahuhopu ʻelua.
Pehea ka loaʻa ʻana o ka ʻili kiʻiʻoniʻoni i nā waiwai pale wai hanu?
Microporous vs. Hydrophilic Non-Porous Technologies
Kiʻiʻoniʻoni breathable wai Hoʻokō ʻia ka hana ma o ʻelua mau mīkini kumu:
- Nā kiʻiʻoniʻoni microporous: Loaʻa i nā pores (0.1–0.5 μm) e ʻae i ka hoʻopuehu ʻana i ka mahu akā e ālai i ka wai wai (ke poʻo hydrostatic > 100 knm).
- ʻO nā kiʻiʻoniʻoni porous hydrophilic: E hoʻohana i ka diffusion molekala ma o nā kaulahao polymer; ʻaʻohe pores, no laila keakea loa i nā maʻi bacteria/virus.
Ka hoʻohālikelike ʻana i ke kaomi ʻana o ka wai a me ka mākū māhu (MVTR).
Aia ma lalo kahi hoʻohālikelike ʻenehana o kēia mau ʻenehana wai hanu ʻelua:
| ʻĀpana | Kiʻiʻoniʻoni Microporous (e.g., ePTFE) | Hydrophilic Non-Porous (e.g., Polyester-based) |
|---|---|---|
| MVTR (g/m²/24h) | 800–1600 | 400–1200 |
| ʻO ke kaomi wai komo (cm H₂O) | >150 | >200 |
| ʻOi aku ka maikaʻi o ka kānana ʻana i ka maʻi bacteria (BFE) | >99% (inā nui ka pore <0.3 μm) | >99.9% (ka pale pale kūlohelohe) |
| Hoʻohana Lapaʻau maʻamau | ʻaʻahu ʻokiʻoki, ʻaʻahu ʻeha | ʻO ka ʻeke pale pale sterile, nā ʻōpala ʻokiʻoki |
Hoʻohana i ka mālama ʻana i nā maʻi ʻeha
Hoʻohui pinepine nā ʻaʻahu ʻeha hou i nā ʻenehana ʻelua: kahi papa waho microporous no ka hanu a me kahi papa hoʻopili ʻeha hydrophilic no ka hoʻokele wai a me ka wehe ʻana i ka atraumatic.
No ke aha e hilinaʻi ai iā Hangzhou Zhongcheng no nā hoʻonā kiʻiʻoniʻoni?
No Hangzhou Zhongcheng Material Technology Co., Ltd.
He ʻoihana hou ʻo Hangzhou Zhongcheng Material Technology Co., Ltd. i ka noiʻi, hoʻomohala, hana a kūʻai aku i nā kiʻiʻoniʻoni plastik, nā kiʻi ʻai meaʻai, nā kiʻiʻoniʻoni olakino, PE/CPP, a me nā kiʻi anti-rust pūʻali koa. Hāʻawi ka hui i nā mea kūʻai aku i nā huahana kiʻiʻoniʻoni kiʻekiʻe me ka ʻenehana kiʻekiʻe a me nā lako hana, nā ʻano hoʻokolohua hoʻokō huahana piha, ʻōnaehana hōʻoia maikaʻi pono, kākoʻo ʻenehana waiwai mua a me ka lawelawe noʻonoʻo ma hope o ke kūʻai aku.
Hiki i ka R&D a me ka ʻOihana Hana Hana
Ua hoʻokumu ʻia ka hui ma 2003 me kahi kapikala i hoʻopaʻa ʻia he 100 miliona yuan. Hoʻopili ka waihona Hangzhou i kahi ʻāpana o 15 mau ʻeka, me kahi hale kūkulu hale hana o 15,000 square square a ʻoi aku ma mua o 100 mau limahana. Ma 2017, ua kūʻai aku ka hui i 19 mau ʻeka o ka ʻāina ma Binjiang District, Hangzhou, a kūkulu i kahi hale hou 25-moʻolelo R&D, Zhongcheng Building, me ka huina kālā o 500 miliona yuan. Ua hoʻohana ʻia a loaʻa ka loaʻa kālā hoʻolimalima makahiki o 30 miliona yuan. ʻO ka hale ke keʻena nui o ka hui a me nā hale hana hou no ka hōʻike kiʻiʻoniʻoni, hōʻoia sterilization, a me ka hoʻāʻo biocompatibility.

- Q: He aha ka ʻokoʻa ma waena o ke kiʻiʻoniʻoni kiʻiʻoniʻoni a me ka kiʻiʻoniʻoni plastik maʻamau?
A: Kiʻiʻoniʻoni ʻO ka mea maʻamau e pili ana i nā kiʻiʻoniʻoni ultra-thin (5-50 μm) i hana ʻia no ka lāʻau lapaʻau a i ʻole nā noi ʻenehana, me nā mana koʻikoʻi i ka maʻemaʻe, MVTR, a me ka biocompatibility, ʻoiai ʻo nā kiʻiʻoniʻoni plastik maʻamau e nele i kēia mau waiwai kūikawā. - Nīnau: Hiki ke hoʻomaʻemaʻe ʻia ke kino kiʻiʻoniʻoni no ka ʻaʻahu ʻeha e ka radiation gamma?
A: ʻAe, nui nā kiʻiʻoniʻoni polyurethane a me nā polyolefin lāʻau lapaʻau i paʻa i ka gamma a hiki i 25-50 kGy. Eia nō naʻe, hiki ke hoʻololi i ka waihoʻoluʻu a i ʻole ka embrittlement liʻiliʻi; koi ʻia ka hōʻoia no ISO 11137. - Nīnau: Pehea wau e hōʻoia ai inā ʻo ka ʻiʻo kiʻiʻoniʻoni he māka lapaʻau maoli?
A: Noi i kahi Pūnaewele Master File (a i ʻole faila ʻenehana) me nā hōʻike hoʻāʻo ISO 10993, ka ʻae ʻana o FDA 510 (k) inā pili, a me nā hōʻike o ka hana GMP ma kahi lumi maʻemaʻe. - Nīnau: He mea kūpono anei ke kiʻiʻoniʻoni biodegradable no nā implants lōʻihi?
A: ʻAʻole—hoʻolālā ʻia nā kiʻiʻoniʻoni biodegradable no ka hoʻohana mau ʻana (e laʻa. Pono nā implants mau i nā mea hiki ʻole ke hoʻoheheʻe ʻia e like me ePTFE a i ʻole polypropylene. - Nīnau: He aha ka manawa alakaʻi maʻamau no ka hoʻokumu ʻana i nā kiʻiʻoniʻoni maʻamau?
A: No nā māka lāʻau lapaʻau i hoʻokumu ʻia, hiki ke hana ʻia nā laʻana i nā wiki 2-4. Pono nā pūʻulu hōʻoia piha i 8-12 mau pule, e pili ana i ka sterilization a me nā koi ʻana.
