Isixhobo sokuSeta oomatshini (VMSR)
Inkcazo
I-sleeve-valve kwindawo yokugcina i-samente ikwindawo evulekileyo ngelixa iqhutyelwa emthonjeni.
Xa inkqubo yokumisela igqityiwe, i-sleeve-valve inokuvalwa ngokuthatha i-intshi ezimbini kwizixhobo okanye ivule ngokuqhawula i-intshi ezimbini.
Isici se-snap-latch sivumela i-sleeve-valve ukuba iguqulwe ivule okanye ivalwe ngelixa i-tubhing isabambelele kwisigcini.
Olunye uphawu lwesixhobo lubonelela ngokuqhuba i-sleeve-valve nokuba ivuliwe okanye ivaliwe. Ngokuqhelekileyo ivalve ivuliwe ukuze i-tubing izalise.
Nangona kunjalo, ukuvavanya uxinzelelo kwi-tubing, ngelixa usebenza, i-valve inokuqhutywa ivaliwe. I-Cement Retainers inokusetwa kwaye uxinzelelo luvavanywe kuhambo olunye.
