Iiglavu zonyango ziiglavu ezilahlwayo ezisetyenziswa kwiimviwo zonyango kunye neenkqubo zokunceda ukuthintela ungcoliseko oluphakathi kwabahlengikazi kunye nezigulane. Iiglavu zonyango zenziwe ngeepolymers ezahlukeneyo, kubandakanya i-latex, irabha ye-nitrile, i-PVC kunye ne-neoprene; Azisebenzisi umgubo okanye umgubo wesitatshi sombona ukuthambisa iiglavu, okwenza kube lula ukuzinxiba ezandleni.
Isitatshi sombona sithatha indawo yepowder efakwe iswekile kunye ne-talc powder evuselela izicubu, kodwa nokuba istatshi sombona singena kwizicubu, sinokuthintela ukuphiliswa (njengakwixesha lotyando). Ke ngoko, iiglavu ezingenayo ipowder zisetyenziswa rhoqo ngexesha lotyando kunye nezinye iinkqubo ezinobuzaza. Inkqubo ekhethekileyo yokuvelisa iyasetyenziswa ukuze kulungiswe ukunqongophala kwepowder.
Iiglavu zonyango
Kukho iintlobo ezimbini eziphambili zeeglavu zonyango: iiglavu zovavanyo kunye neeglavu zotyando. Iiglavu zotyando zichaneke ngakumbi ngobukhulu, ziphezulu ngokuchanekileyo nangobuntununtunu, kwaye zifikelela kumgangatho ophezulu. Iiglavu zovavanyo zinokuba zingenazintsholongwane okanye zingabi zintsholongwane, ngelixa iiglavu zotyando zihlala zingenazintsholongwane.
Ngaphandle kwezonyango, iiglavu zonyango zisetyenziswa kakhulu kwiilebhu zeekhemikhali nezebhayoloji. Iiglavu zonyango zibonelela ngokhuseleko olusisiseko ekungcoleni nasekungcoleni komphezulu. Nangona kunjalo, zingena lula kwizinyibilikisi kunye neekhemikhali ezahlukeneyo eziyingozi. Ke ngoko, xa umsebenzi ubandakanya ukuntywilisela izandla zeeglavu kwizinyibilikisi, musa ukuzisebenzisa ekuhlambeni izitya okanye kwezinye iindlela.
Ukuhlelwa kobungakanani beeglavu zonyango
Ngokubanzi, iiglavu zokuhlola zii-XS, s, m kunye ne-L. Ezinye iimpawu zinokubonelela ngobukhulu be-XL. Iiglavu zotyando zihlala zichanekile ngobukhulu kuba zifuna amaxesha amade okuguguleka kunye nokuguquguquka okugqwesileyo. Ubungakanani beeglavu zotyando busekelwe kumjikelezo olinganisiweyo (ngee-intshi) ojikeleze intende yesandla kwaye buphezulu kancinci kunenqanaba lokuthunga ubhontsi. Ubungakanani obuqhelekileyo buqala kwi-5.5 ukuya kwi-9.0 ngokunyusa okungu-0.5. Ezinye iimpawu zinokubonelela ngobukhulu be-5.0 obufaneleke ngakumbi koogqirha basetyhini. Abasebenzisi beeglavu zotyando okokuqala banokufuna ixesha elithile ukuze bafumane ubungakanani kunye nophawu olufanelekileyo lwejometri yezandla zabo. Abantu abaneentende ezinkulu banokufuna ubukhulu obukhulu kunokulinganiswa, kwaye ngokuchaseneyo.
Uphononongo olwenziwe kwiqela loogqirha baseMelika lufumanise ukuba ubukhulu obuqhelekileyo beeglavu zotyando zamadoda yayiyi-7.0, ilandelwe yi-6.5; 6.0 kubafazi, ilandelwe yi-5.5.
Umhleli weeglavu zomgubo
Umgubo usetyenzisiwe njengesithambisi ukuze kube lula ukunxiba iiglavu. Iipowders zokuqala ezithathwe kwipayini okanye kwi-club moss zifunyenwe zinetyhefu. Umgubo we-talc usetyenzisiwe amashumi eminyaka, kodwa unxulumene ne-granuloma emva kotyando kunye nokwakheka kwamanxeba. Esinye isitashi sombona esisetyenziswa njengesithambisi sifunyenwe sineziphumo ebezingalindelekanga, ezinje ngokudumba, i-granuloma kunye nokwakheka kwamanxeba.
Susa iiglavu zonyango ezimpunga
Ngokufika kweeglavu zonyango ezingasebenzisi mgubo ezilula ukuzisebenzisa, ilizwi lokususa iiglavu ezisebenzisa umgubo liyakhula. Ngowama-2016, azisayi kusetyenziswa kwiinkqubo zonyango zaseJamani nase-UK. NgoMatshi 2016, i-US Food and Drug Administration (FDA) yakhupha isindululo sokuthintela ukusetyenziswa kwazo kwezonyango, yaza yapasisa umthetho ngoDisemba 19, 2016 wokuthintela zonke iiglavu ezisebenzisa umgubo ukuba zisetyenziswe kwezonyango. Le mithetho yaqala ukusebenza ngomhla we-18 kuJanuwari 2017.
Iiglavu zonyango ezingenamgubo zisetyenziswa kwiindawo ezicocekileyo zezonyango apho imfuneko yokucoca idla ngokufana nococeko kwiindawo ezibuthathaka zezonyango.
ukucoca nge-chlorine
Ukuze kube lula kubo ukunxiba ngaphandle komgubo, iiglavu zinokunyangwa nge-chlorine. I-chlorination inokuchaphazela ezinye iipropati eziluncedo ze-latex, kodwa ikwanciphisa ubungakanani beeproteni ze-latex ezivakalayo.
Umhleli weeglavu zonyango eziphindwe kabini
Ukunxiba iiglavu yindlela yokunxiba iiglavu zonyango ezinemigangatho emibini ukunciphisa umngcipheko wosulelo olubangelwa kukungasebenzi kakuhle kweeglavu okanye izinto ezibukhali ezingena kwiiglavu kwiinkqubo zonyango. Xa uphatha abantu abanezifo ezisulelayo ezifana ne-HIV kunye ne-hepatitis, oogqirha kufuneka banxibe iiglavu ezimbini ezineminwe ukuze bakhusele ngcono izigulana kwizifo ezinokuthi zisasazwe ngoogqirha. Uphononongo olucwangcisiweyo lweencwadi lubonise ukuba i-hand cuff ezimbini inika ukhuseleko olukhulu ngexesha lotyando kunokusebenzisa umaleko weglavu enye ukuthintela ukugqobhoka ngaphakathi kweglavu. Nangona kunjalo, akucaci ukuba kukho amanyathelo angcono okukhusela usulelo phakathi koogqirha. Olunye uphononongo olucwangcisiweyo luhlolisise ukuba i-hand cuff ingabakhusela ngcono na oogqirha kwizifo ezosulelayo kwizigulana. Iziphumo ezidityanisiweyo zabathathi-nxaxheba abangama-3437 kwizifundo ezili-12 (ii-RCT) zibonise ukuba ukunxiba iiglavu ezineeglavu ezimbini kunciphisa inani lokugqobhoka kwiiglavu zangaphakathi ngama-71% xa kuthelekiswa nokunxiba iiglavu ngenye. Ngokomyinge, oogqirha/abahlengikazi abali-10 abathathe inxaxheba kwimisebenzi eli-100 baya kugcina ukugqobhoka kweglavu enye eli-172, kodwa iiglavu zangaphakathi ezingama-50 kuphela eziya kufuneka zigqobhoke ukuba banxibe izigqubuthelo zezandla ezimbini. Oku kunciphisa umngcipheko.
Ukongeza, iiglavu zekotoni zinokunxitywa phantsi kweeglavu ezilahlwayo ukuze kuncitshiswe ukubila xa unxibe ezi glavu ixesha elide. Ezi glavu zineglavu zinokucocwa kwaye zisetyenziswe kwakhona.
