Zotchuka kuchokera ku zakalegawo la zamankhwalas ziyenera kuwerengedwa, chifukwa zimaphatikizapo kukonzanso thupi, pakadali pano pali zinthu zambiri zomwe zili mumakampani, zofunikira pazida zosiyanasiyana zimasankhidwa, zinthu za silicone sizosiyana kwambiri, chifukwa chake popeza zinthu za silicone zili mumakampani azachipatala, zomwe timatcha silicone yachipatala ndi zabwino ziti zomwe mukudziwa!

Zinthu za silicone zimakhala ndi mphamvu yodziletsa komanso kukhazikika bwino, mphamvu zake zamakanika zimakhala zapamwamba, zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, makampani azachipatala ndi amodzi mwa iwo okha, ndipo kuchokera ku zinthu zachipatala kuti zikwaniritse zofunikira zina zingagwiritsidwe ntchito m'munda wazachipatala. Kusiyana kuli mu kuchuluka kwa ma micro-pores a silicon molecular, unyolo wolimba wa mamolekyulu ndi kukhazikika kwakukulu.

Zifukwa zisanu ndi zitatu za silicone ngati chinthu chabwino kwambiri pakupanga zida zachipatala:

1. Unyolo waukulu wa okosijeni wa silicon umapereka kukhazikika kwabwino kwa kutentha.
Silicone ili ndi kutentha kolimba kwambiri, zomwe zimathandiza kuti zipangizo zisunge zinthu zofunika kwambiri ngakhale zitatha kuyeretsa. Silicone imatha kuyeretsa pogwiritsa ntchito kuyeretsa nthunzi yotentha kwambiri, kuyeretsa epoxy zane (EtO), kapena Y radiation.

2. Silicone ndi chinthu chosagwira ntchito.
Silicone nthawi zambiri imakhala yosagwira madzi ndi mankhwala, ndipo ilibe fungo. Kapangidwe kake ka mankhwala kakukwaniritsa miyezo ya USP Class VI ndi ISO 10993.

3. Silikoni ilibe pulasitiki kapena zowonjezera zina zachilengedwe.
Chopangira pulasitiki kapena zowonjezera zina zachilengedwe zingakhale ndi zotsatirapo zoyipa pakupereka mankhwala, ngati zowonjezerazo zilipo, n'zotheka kusamukira ku mankhwala amadzimadzi ndipo silica gel ilibe zowonjezera monga pulasitiki kapena zowonjezera zachilengedwe.

4. Silikoni ndi yolimba.
Silicone imakhala ndi kusinthasintha kwabwino komanso imachira bwino ikabowoledwa kuti ichepetse kutopa kwa zinthu. Zinthu zofunikazi zimapangitsa kuti silicone ikhale ndi moyo wautali, ngakhale ikapanikizika kwambiri.

5. Silikoni ili ndi modulus yochepa.
Silicone imafuna mphamvu zochepa zoyikira kuti chipangizocho chigwire bwino ntchito — kapena chikhale chosavuta kusonkhanitsa chikaphatikizidwa ndi zida zina.

6. Silikoni ingapangidwe kukhala yolimba mosiyanasiyana.
Silicone imatha kupangidwa mosiyanasiyana kuti igwirizane ndi zinthu zolimba kwambiri kapena zofewa kwambiri, zomwe zimapangitsa kuti pakhale ergonomics yabwino komanso chitonthozo.

7. Silikoni ili ndi mawonekedwe abwino okongoletsa.
Ma silicone elastomer ambiri ndi owonekera bwino ndipo nthawi zambiri amapakidwa utoto mosavuta.

8. Silicone ndi yosavuta kuikonza.
Kuwonjezera pa kuuma kwake, chitonthozo chake, komanso mawonekedwe ake okongola, silicone imapereka njira zosiyanasiyana zosinthira. Zipangizo zitha kugwiritsidwa ntchito pazida zosiyanasiyana ndi mapangidwe, kuyambira ma catheter olowetsedwa mpaka ma valve odulidwa mpaka masks opumira. Njira zina zosinthira ndi monga mphamvu yokoka, nthawi yokwanira yokankhira, nthawi yochira komanso kutalika kwake.

Kugwiritsa ntchito zinthu za silicone mu zida zachipatala.

Zipangizo zogwirira khungu la munthu:
(1) Chigoba chopumira: makamaka chigoba cha silicone chomwe chimayenera kuvalidwa kwa nthawi yayitali.
(2) Kusamalira mabala: Gel ya silicone ndi yabwino kwambiri pakhungu komanso yopumira, ndipo siingayambitse kuvulala kwina pabala. Chifukwa chake, Gel ya Magtu silicone ndi chisankho chabwino chopaka thovu, kupaka mabala, ndi zina zotero.
(3) Zogwirira zida: Zogwirira zofewa komanso zosaterera ziyenera kugwiridwa pa zida zachipatala zomwe ziyenera kugwiridwa, monga mipeni yopangira opaleshoni.

Zipangizo zolumikizirana ndi ziwalo za thupi la munthu:
Chigoba cha silicone laryngeal: chikakhudzana ndi trachea, silicone imakhala yofewa komanso yamphamvu kuti mpweya ukhale wosalala.
Ma catheter a silicone: Silicone imathandizira kupanga matupi a machubu osinthasintha komanso mabaluni amphamvu kwambiri.
Chubu cha m'mimba cha silikoni: kuuma koyenera, chubu cha m'mimba cha silikoni ndi chisankho chabwino kwa odwala.

Chida cholumikizira magazi a anthu ndi madzi amthupi:
Catheter ya chipangizo cholowetsera: monga chubu cha pampu ya peristaltic ya pampu yolowetsera, chubu chakunja cha catheter ya silicone yoyikidwa.
Zigawo za zida zolowetsera: monga pulagi ya silicone yopanda singano, silicone O-ring ya fyuluta ya dialysis ya impso, ndi zina zotero.
Mapulagi apulasitiki ndi ma valve oyeretsera magazi m'mitundu yonse ya zinthu zogwiritsidwa ntchito zachipatala zomwe zimagwirizana ndi madzi achipatala ndi madzi amthupi.
Kuphatikiza apo, silica gel ingagwiritsidwe ntchito m'njira zosiyanasiyana, kuyambira magalasi olumikizana mpaka zida zoyesera zamankhwala zomwe zingathe kuvala, kuyambira mankhwala achilengedwe mpaka kafukufuku ndi chitukuko cha katemera, silica gel ingagwiritsidwe ntchito kwambiri m'munda.
