Pamene makampani azachipatala akupitirizabe kukula, zipangizo zamankhwala ndi zipangizo zikupita patsogolo kwambiri kuti zigwirizane ndi mankhwala ovuta, mankhwala ndi kutentha. Kusankha chisindikizo choyenera pazachipatala ndikofunikira kuti chipangizochi chizigwira ntchito.
Zisindikizo zachipatala zimagwiritsidwa ntchito zosiyanasiyana, kuphatikizapo mapampu azachipatala, zigawo za IV, zipangizo zodyetserako zakudya komanso zopangira. Cholinga cha zisindikizo zachipatala ndikuteteza anthu onse ndi zipangizo kuti zisawonongeke zowonongeka. Amagwiritsidwa ntchito pamene zakumwa kapena mpweya umapopedwa, kutsanulidwa, kusamutsidwa, kusungidwa kapena kuperekedwa.
Pali zinthu zambiri zomwe muyenera kukumbukira posankha chisindikizo choyenera cha chipangizo chachipatala. Nazi zina mwazinthu zapamwamba zomwe muyenera kuziganizira popanga chisankho.
Sankhani bwino elastomer zakuthupi.
Kuti musankhe chisindikizo choyenera, muyenera kumvetsetsa kaye ntchito yomwe ili pafupi. Muyenera kuganizira zomwe zingatheke kukhudzana, kutentha, kuyenda, kuthamanga ndi kutalika kwa chisindikizocho.
Zisindikizo zachipatala ziyenera kuwonetsa kukana mankhwala owopsa, oopsa. Pakhoza kukhala zofunikira zenizeni za zinthu za elastomer za chisindikizo. Pofuna kupirira ndikuwonetsetsa kukana kwa mankhwala, ndikofunika kuti chisindikizocho chipangidwe kuchokera ku elastomers ndi ntchito yabwino kwambiri komanso yabwino kwambiri. Apple Rubber imagwiritsa ntchito Rubber ya Liquid Silicone, Viton® Fluoroelastomer ndi Ethelyne-Propylene. Ma elastomer awa apititsa patsogolo zopinga za mankhwala, kukana kutentha kwambiri komanso kutsika kochepa kwa gasi.
Dziwani za biocompatibility.
Zida zamankhwala sizimalumikizana nthawi zonse ndi minofu yamoyo. Komabe, zida ndi zisindikizo zikakhudza minofu yamunthu ndi zinthu zina zofunika monga madzi am'thupi, mankhwala osokoneza bongo kapena zachipatala, ndikofunikira kuzindikira kuyanjana kwazinthu zosindikizira.
Biocompatibility imatanthawuza kuti zida za zinthu zimagwirizana mwachilengedwe ndipo sizipereka zomwe zimachitika kapena kuyankha ku minofu yamoyo. Kuti mutsimikizire kuti palibe zomwe zidzachitike panthawi yachipatala, ndikofunikira kuyesa kuyanjana kwa chisindikizo ndikusankha zinthu kutengera mtundu wa ntchito ndi ntchito.
Zida zina zimakhala ndi zonyansa.
Nthawi zonse ndikofunikira kuganizira zodetsa za zinthu zosindikizira. Pakapita nthawi, zonyansa zimatha kutuluka mu chisindikizo ndi zinthu zapoizoni kapena carcinogenic. M'magwiritsidwe azachipatala pomwe zida ndi zosindikizira zimalumikizana mwachindunji ndi minofu yamunthu, nthawi zina ngakhale kubzalidwa, ndikofunikira kwambiri kudziwa za kuopsa kwa chinthu. Pachifukwa ichi, mainjiniya ayenera kusankha chosindikizira chopanda zinyalala.
Pansi pa kuwala komweko, ndikofunikira kuzindikira ngati zinthuzo ziyenera kutsekeredwa. Pokhudzana ndi kukhudzana ndi minofu yamoyo, chipangizo chonse chachipatala chiyenera kukhala chosabala kuti chiteteze matenda.
Mukufuna kulankhula zambiri za zisindikizo zachipatala?
