Ko te ngira werohanga tētahi o ngā taputapu hauora tino hokohoko o te ao. Heoi, he mea tika kia aro atu ki te meka e miriona ngā tāngata e whara ana i ia tau i ngā hōhipera huri noa i te ao nā te whati o te ngira, nā te mahi hē rānei o ngā kaimahi hauora. E whakaatu ana ngā tatauranga i tukuna e te American Medical Association e tata ana ki te 1 miriona ngā kaimahi hauora e werohia ana e rātou anō ki ngā ngira i ia tau i te United States anake, ā, neke atu i te 1,000 o rātou e pangia ana e te mate hepatitis B, hepatitis C me te HIV. Ko te utu mō te maimoatanga ohorere mō ngā kaimahi hauora me ngā tūroro i whara i te ngira toto whati he 3,000 tāra ia tangata.
[0003] Kāore i te iti iho ngā mōrearea hauora e pā ana ki ngā ngira noa i ērā e pā ana ki ngā ngira werohanga. Kua kaha te aro o ngā kamupene o te kāinga me tāwāhi ki te werohanga haumaru i roto i te rangahau me te whakawhanake i ngā taputapu hauora, engari he maha ngā taputapu werohanga haumaru kei te mākete: ko tētahi ko te utu nui o te hanga, ko tētahi he tukanga whakaputa uaua; ko te tuatoru ko te uaua ki te kī taurangi i te kounga o te hanga; tuawhā, he hoha ngā kaimahi hauora; ko te tuarima he uaua ki te whakarite i te mahi haumaru. Hei tāpiri, he kikī rawa te ngira werohanga nā ngā take nui i roto i te tukanga tango. [0004] Nō reira, he nui te hiranga o te whakawhanaketanga o te ngira werohanga haumaru tango-whakakore hei whakawhanake i te ngira werohanga haumaru tango-whakakore. Nō reira, he mea tino nui te ngira werohanga haumaru. Ka taea e mātou te whakarato ki a koe he ratonga kounga teitei me te kounga teiteingā werohanga haumarungira haumaruPūwero RetractalbeMono aunoa i te ngira.
Nō reira, mā te hono i ngā tuaiwi 14, ka taea te hono ngāwari i te ngira werohanga ki waho ki ētahi atu wāhanga, ā, ka whānui ake te whānuitanga o te whakamahinga o te ngira werohanga. [0031] Hei tāpiri, i roto i te mokowā kāri me te tihi o te wāhanga 12 kua rite ki te tokotoko matua mō te 121, 2 i roto i te wāhanga o runga o te koti he koti mō te 21, ina kumea te tokotoko matua 1 ki runga ki te tihi o te koti 2, ka pa te mandrel mō te 121 me te koti mō te 21, ka taea te whakamahi i te pae matua mō te 121 me te koti mō te 21 i ia whitiki kāri, kāore e taea te hiki ake i te tokotoko matua 1, ka taea te ārai i te kume [0032]. Hei tāpiri, hei whakahaere i te whakaputanga, ka taea te hono i te tokotoko matua 1 mā ngā tokotoko e rua i waenganui, i waenganui i te tokotoko mā te urunga urunga me te piri piri, kia mau ai te hononga i waenganui i ngā mea e rua. [0033] E ai ki te hanganga i runga ake nei, ko te whakamahinga motuhake o tēnei mea hou e whai ake nei: kua whakaahuatia me ngā hua werohanga he ngira werohanga haumaru. Kia oti te werohanga, ka pana whakamua te paninga 2, ka puta he nekehanga whanaunga o te piston 5 ki te paninga 2, ka panaia te nekehanga whanaunga o te paninga mandrel 1 me te 2 kia tae rā anō ki te rākau matua mō ngā mata 121 ki te 21 kia pania. I tēnei wā, ka huna te ngira 3 i roto i te paninga 2, kia kore ai e kitea te ngira 3, kia kore ai hoki e werohia. He ngāwari te hanganga o te ngira werohanga haumaru kua whakaahuatia i roto i te mea hou, ā, he watea hoki te whakamahinga, ka taea ai te ārai i te whara o te ngira werohanga, me te whakaiti nui i te mōrearea hauora o te ngira werohanga.
