he aha te kaha porowhita e whakamahia ana hei wehe i te toto
Kupu Whakataki
He ariā taketake te kaha pūwero i roto i te ahupūngao e whai wāhi nui ana ki ngā momo ahumahi, tae atu ki te rongoā me te tiaki hauora. I roto i te mara o te tātaritanga hauora, ka whakamahia te kaha pūwero hei wehewehe i ngā wāhanga toto hei mahi i ngā momo whakamātautau, pērā i te tatau pūtau toto, te momo toto, me te tātari i ngā tohu matū rerekē. Ko te whāinga o tēnei tuhinga he whakamārama he aha te kaha pūwero, me pēhea te whakaputa, me pēhea te whakamahinga hei wehewehe i ngā wāhanga toto me te whai hua.
1. Te Mārama ki te Kaha Pūtahi
He kaha rūpahu te kaha pūwero e āhua nei ka pā ki tētahi tinana e neke ana i te ara porowhita. Ahakoa te āhua nei kei te kukume te kaha i ngā mea kia matara atu i te pokapū o te hurihanga, he kaha ki waho tonu i puta mai i te koretake o te mea. I te mea he matū wai te toto, ka whai i ngā mātāpono o te hihiri wai, ā, he pai mō te wehe mā te whakamahi i te kaha pūwero.
2. Ngā Mīhini Whakapūtā: He Tirohanga Tata
He taputapu motuhake ngā mīhini whakapūtā e whakamahia ana puta noa i ngā momo taiao hauora hei wehewehe i ngā wāhanga toto. Ko te mahi a ēnei mīhini i runga i te kaupapa o te kaha whakapūtā, ā, he huihuinga hurihuri kei roto e hurihuri ana i ngā tere teitei. Ka whakanohoia te tauira toto ki roto i ngā ngongo, i ngā ipu rānei i roto i te hurihuri, ā, ka hurihia kia kaha, ka mutu ka wehea ngā wāhanga rerekē.
3. Te Hanganga o te Toto
I mua i te ruku hohonu ki te tukanga wehenga toto mā te whakamahi i te kaha porotītaha, he mea nui kia mārama ki te hanganga o te toto. He rerekē ngā wāhanga o te toto, tae atu ki ngā toto whero (erythrocytes), ngā toto mā (leukocytes), ngā pereti toto (thrombocytes), me te plasma. He rerekē ngā matotoru me ngā rahi o ēnei wāhanga, ā, he ngāwari ki te wehe mā te porotītaha.
4. Te Tukanga Wehewehe Toto
He maha ngā mahi e whai wāhi ana ki te tukanga wehenga toto hei whakarite kia whai hua te wehenga o ōna wāhanga. Tuatahi, ka kohia te tauira toto mai i te tūroro mā te whakamahi i tētahi ngira, i tētahi ngongo kohikohi motuhake rānei. Muri iho, ka ata whakawhitia te tauira ki roto i ngā ngongo i hangaia mō te centrifugation. Ko te tikanga, ka tohua ēnei ngongo ki te tere mōrahi ka taea te centrifugate kia kore ai e pakaru.
5. Te Kōwhiri i te Tere me te Wā e Tika ana mō te Pūwero
Hei whakatutuki i te wehenga tino pai o ngā wāhanga toto, he mea nui kia whiriwhiria te tere me te roa e tika ana mō te centrifugation. He rerekē te matotoru me te rahi o ngā wāhanga toto rerekē, e hiahiatia ana he rerekē ngā tawhā centrifugation. Hei tauira, mō te tatau pūtau toto taketake, he nui pea te tere iti me te wā poto ake, engari ko ngā whakamātautau uaua ake me tere ake me roa ake.
6. Te Tukanga Wehewehe
Kia mau te whakanoho o ngā ngongo kei roto te tauira toto ki roto i te centrifuge, ka tīmata te hurihuri tere o te rotor. Ka hangaia e te nekehanga hurihuri he kaha centripetal e pana ana i ngā wāhanga toto matotoru ki raro o te ngongo, ko ngā wāhanga iti ake te matotoru ka noho tata ki runga. Mā tēnei, ka wehea ngā wāhanga toto ki ngā paparanga motuhake, ka taea te uru atu me te tātari ngāwari.
7. Te tiki me te tātari i ngā wāhanga toto kua wehea
Kia oti te tukanga centrifugation, ka taea te tango marie i ngā wāhanga toto kua wehea mā te whakamahi i tētahi pipette, i ētahi atu taputapu motuhake rānei. Kātahi ka tukuna ngā paparanga, tae atu ki ngā toto whero kua tākaihia ki raro, te buffy coat (he paparanga angiangi o ngā toto ma me ngā platelets), me te plasma i runga, ki ētahi atu tātaritanga me ngā whakamātautau tātaritanga.
Whakamutunga
He kaupapa nui te kaha whakatere e whakamahia ana i roto i ngā taiwhanga hauora me ngā whare tiaki hauora hei wehewehe i ngā wāhanga toto. Mā te whakamahi i te mana o te whakatere, ka taea e ngā tohunga hauora te whiwhi mōhiohio nui mō te hauora o te tūroro me te whakatau tika i ngā mate. Mā te mārama ki te mahi a te kaha whakatere me tōna whakamahinga i roto i te wehenga toto ka taea e ngā tākuta hauora te whakarato i te tiaki pai ake mō te tūroro me te whakapai ake i ngā putanga tiaki hauora.
