Me pēhea te mahi a te centrifuge hei wehe i te toto
He taputapu taiwhanga nui te centrifuge e whakamahia whānuitia ana i roto i ngā mara pūtaiao me ngā mara hauora. Ko tētahi o ōna whakamahinga matua ko te wehewehe i ngā wāhanga toto mō ngā take tātaritanga me ngā rangahau. I roto i tēnei tuhinga, ka tūhuratia e mātou te mahi a te centrifuge ki te wehewehe i te toto me ngā āhuatanga rerekē e whai wāhi ana ki tōna whai huatanga.
Te Mārama ki te Hanganga o te Toto
I mua i te ruku hohonu ki ngā mahi a te centrifuge, he mea nui kia mārama ki te hanganga o te toto. Ko te toto te nuinga o ngā mea he toto whero (erythrocytes), he toto mā (leukocyte), he pereti toto (thrombocytes), me te plasma. He mahi motuhake tā ia wāhanga ki te pupuri i te hauora whānui o te tinana.
1. Te Kaupapa o te Wehenga Toto
He mea nui te wehenga toto mō ngā tikanga hauora maha me ngā rangahau taiwhanga. Mā te wehewehe i ngā wāhanga motuhake o te toto, ka taea e ngā kairangahau me ngā tohunga hauora te whiwhi māramatanga nui ki ngā mate, te mahi whakamātautau tātaritanga, me te whakawhanake i ngā maimoatanga hou. Hei tāpiri, mā te wehenga toto ka taea te kohikohi i ngā wāhanga pēnei i te plasma, i ngā pereti toto rānei, ka taea te whakamahi mō ngā kaupapa rongoā maha.
Te Mātāpono Mahi o te Pūwhakarewa
Ko te kaha pūwero te pūtake o te mahi a te pūwero. Ka mahi tēnei kaha ki waho mai i te pokapū o te hurihanga, ā, ka heke ngā matūriki matotoru i roto i te tauira ki te taha, ko ngā matūriki māmā ake ka neke ki te pokapū. Mā tēnei mātāpono ka taea te wehewehe i ngā wāhanga toto i runga i ō rātou matotoru rerekē.
2. Te Kaha Pūwero: Te Whakaterenga Pūwero me te Pūwero
He maha ngā wā ka whakaarohia he kaha tūturu te kaha pūwero. Ko te mea pono, ka puta mai i te whakaterenga pūwero, arā, te kaha e anga ana ki roto, ka puta ai te nekehanga porohita (hei tauira, te hurihuri o te rotor pūwero). Ko te whakaterenga pūwero te kaha rūpahu e pāngia ana e ngā matūriki i roto i te pūnaha hurihuri e pana ana i a rātou ki waho. Mā te whakataurite i ēnei kaha e rua, ka puta te wehenga e hiahiatia ana e te pūwero.
Ngā momo pūwhakapūngao
He maha ngā momo pūwero e wātea ana, tae atu ki ngā pūwero iti, ngā pūwero papa, ngā pūwero tere-rahi, me ngā pūwero tino-rahi. He rerekē ia momo i runga i te tere hurihuri, te kaha, me te whakamahinga. Ko ngā pūwero tino-rahi, ka taea te eke ki ngā tere whakamiharo, he tino whai hua mō te wehenga toto nā te mea ka taea e rātou te wehe i ngā matūriki iti rawa.
3. Te Tere me te Wā Hurihanga: Ngā Take e Pā Ana ki te Wehenga Toto
He mea nui te tere hurihuri me te wā, ā, he pānga nui tēnei ki te whai huatanga o te wehenga toto i roto i te mīhini hurihuri. Mā te tere hurihuri teitei ake ka nui ake ngā kaha o te nekehanga me te nekehanga o te tauira, ka pai ake te tukanga wehenga. Heoi, mā te tere nui rawa ka kino pea ngā wāhanga pakarukaru, ā, he mea nui te arotau. Ko te wā tētahi atu mea nui, nā te mea ka taea te wehenga rawaka, inā koa ka uru mai ngā wāhanga matotoru ake, pērā i ngā toto toto whero.
Ngā Momo Rotoru Whakapūtahi
Ka pupuri ngā rotor centrifuge i ngā ngongo tauira i a rātou e hurihuri ana i roto i te centrifuge. Ko te whiriwhiri i te momo rotor ka whakawhirinaki ki ngā whakaritenga motuhake o te mahi wehewehe toto. Ka whakanohohia ngā ngongo e ngā rotor koki-pūmau ki tētahi koki pūmau i te wā e hurihuri ana, ko ngā rotor peere-pōturi ia ka nekehia ngā ngongo ki roto, ki waho hoki i te mara centrifuge i a rātou e hurihuri ana.
4. Kōwhiringa Rotor: Te Whakanui i te Whai Hua o te Wehenga Toto
He mea nui te whiriwhiri i te rotor hei whakatutuki i ngā hua tino pai o te wehenga toto. E whakamahia whānuitia ana ngā rotor koki-pūmau mō ngā mahi whānui, engari ko ngā rotor peere-hurihuri te mea e pai ake ana mō ngā wehenga ngawari, nā te mea ka whakaitihia te tūponotanga o te kino o ngā wāhanga pakarukaru. Mā te whiriwhiri tika ka noho motuhake ngā wāhanga toto e hiahiatia ana, ka taea ai te tātari tika me te whai hua o ngā tono i muri mai.
Ngā Wero me ngā Whakatūpato i roto i te Wehenga Toto
Ahakoa he tikanga kaha te centrifugation mō te wehenga toto, me whai whakaaro ki ētahi wero me ngā mahi whakatūpato kia whiwhi ai i ngā hua pono. Tuatahi, he mea nui te whiriwhiri i te rahi me te momo o te ngongo tika hei karo i te turuturu o te tauira, te poke whakawhiti, me te wehenga hē. Tuarua, he mea nui te pupuri i te taurite tika i roto i te rotor centrifuge hei whakaiti i ngā wiri me te ārai i te kino o te rotor.
5. Ngā Whakatūpato: Ngā Tikanga Pāmahana me te Whakapūtanga
He mea nui te whakahaere i te pāmahana i te wā o te tukanga whakapūtātanga hei tiaki i te kounga o ngā wāhanga toto. Ka taea e ngā pāmahana tino nui te whakakore i te āhua o ngā pūmua, ā, ka pā ki te kounga whānui o ngā wāhanga kua wehea. Heoi anō, he mea nui te whai i ngā tikanga whakapūtātanga kua whakamanahia mō ngā tikanga wehenga toto kia whiwhi ai i ngā hua ōrite, kia taea ai hoki te whakaputa anō i ngā whakamātautau, i ngā whakamātautau haumanu rānei.
Hei whakamutunga, he mea nui te mārama ki te mahi a te centrifuge ki te wehewehe i te toto hei whakahaere i ngā whakamātautau tātaritanga tika, ngā rangahau, me ngā tikanga rongoā. Mā te whakamahi i ngā mātāpono o ngā kaha centripetal me te centrifugal, me te kōwhiringa rotor tika me ngā tikanga tupato, ka taea e te centrifuge te whakamahi i te pūmanawa nui o ngā wāhanga toto i roto i ā rātou ake mara.
