Inaliti yokutofa yenye yezona zixhobo zonyango zithengisa kakhulu kwihlabathi. Nangona kunjalo, kuyafaneleka ukunikela ingqalelo kwinto yokuba izigidi zabantu zonzakala minyaka le kwizibhedlele kwihlabathi liphela ngenxa yokuqhekeka kwenaliti okanye ukusebenza ngokungafanelekanga kwabasebenzi bezonyango. Ubalo olukhutshwe yiAmerican Medical Association lubonisa ukuba abasebenzi bezempilo abamalunga nesigidi bazihlaba ngeenaliti ngempazamo nyaka ngamnye eUnited States kuphela, yaye ubuncinane abali-1 000 kubo bosulelwa yihepatitis B, ihepatitis C neHIV. Iindleko zonyango olungxamisekileyo kubasebenzi bezonyango kunye nezigulane ezonzakele ngenaliti yegazi eyaphukileyo yi-3,000 yeedola kumntu ngamnye.
[0003] Imingcipheko yezonyango eyayanyaniswa neenaliti eziqhelekileyo ayikho ngaphantsi kwezo zinxulumene neesirinji. Iinkampani zasekhaya nakwamanye amazwe ziye zangena ngamandla kwi-injection ekhuselekileyo kuphando lwezixhobo zonyango kunye nophuhliso, kodwa kukho izixhobo ezininzi ze-injection ekhuselekileyo ezikhoyo kwiimarike: enye yindleko ephezulu yokuvelisa, enye yinkqubo yokuvelisa eyinkimbinkimbi; eyesithathu umgangatho wemveliso kunzima ukuqinisekisa; okwesine, abasebenzi bezonyango abadinayo; ezintlanu kunzima ukuqinisekisa umsebenzi okhuselekileyo. Ukongeza, inaliti yenaliti iqinile kakhulu ngenxa yezizathu eziphathekayo kwinkqubo yokuhlehla. [0004] Ke ngoko, uphuhliso lwenaliti yokhuseleko lokurhoxisa elahlayo inobaluleko olukhulu kunye nexesha elide ukuphuhlisa inaliti yokhuseleko enokurhoxiswa. Ngoko ke, isirinji ekhuselekileyo ibaluleke kakhulu. Singakunika iinkonzo ezikumgangatho ophezulu kunye nomgangatho ophezuluiisirinji ezikhuselekileyoinaliti inaliti yokhuselekoIsirinji yeRetractalbeIsirinji ingasebenzi ngokuzenzekela.
Ngaloo ndlela, ngokudibanisa i-vertebrae ye-14, inaliti ye-injection inokudibaniswa ngokulula ngaphandle kwezinye iindawo, ngaloo ndlela yandisa uluhlu lokusetyenziswa kwenaliti yenaliti. [0031] Ngapha koko, kwikhadi lekhadi elinomphezulu wesebe le-12 lixhotyiswe ngentonga engundoqo ye-121, i-2 ngaphakathi kwendawo ephezulu yedyasi inedyasi ye-21st, xa intonga ye-1 idonsa phezulu. phezulu kwedyasi 2, mandrel for 121 kunye nedyasi for 21 zoqhagamshelwano, bar core for 121 kunye idyasi for 21 ikhadi ngalinye buckle, intonga core 1 ayisakwazi ukuphakama phezulu, unako ukuthintela ngempumelelo ukutsalwa [0032] Ukongeza, ukuze ukuququzelela imveliso, intonga ye-core 1 inokudibaniswa ngeentonga ezimbini kwindawo ephakathi, phakathi kwentonga ngokusebenzisa ukuphazamiseka kwentloko kunye ne-glue bonding, ukwenzela ukuba kuqinisekiswe ngakumbi ukuqina kokudibanisa phakathi kwezi zibini. [0033 ngokwesi sakhiwo singentla, ukusetyenziswa okuthe ngqo kokuqanjwa kwangoku kunje kulandelayo: kuchazwe ngeemveliso zokufakela inaliti ekhuselekileyo yesitofu. Xa ukufakwa kugqityiwe, idyasi 2 tyhala phambili, piston 5 idyasi isalamane 2 ukuvelisa isalamane displacement, eqhuba idyasi mandrel 1 kunye 2 intshukumo isalamane kwenzeka de intonga core for 121 ukuba 21 izikrini idyasi. Ngeli xesha, inaliti ye-3 ifihliwe ngaphakathi kwejacket 2, ukwenzela ukuba inaliti ye-3 ingabonakali kwaye ihlatywe ngengozi. Inaliti yokhuseleko echazwe kwimveliso inesakhiwo esilula kunye nokusetyenziswa okufanelekileyo, okunokuthi kuthintele ngokufanelekileyo ingozi yokulimala kwenaliti kunye nokunciphisa kakhulu umngcipheko wonyango wenaliti yokutofa.
