Ibicuruzwa birambuye:
1.Hidrophilique yometseho sheath iba nziza cyane ikimara gukora inkari.
2.Uburyo bushya bwo gufunga uburyo bwo gufunga kuri hub ya dilator butuma dilator igera kumurima kugirango icyarimwe icyarimwe gitezimbere icyatsi na dilator.
3.Icyuma cya spiral cyinjijwe imbere muri sheath hamwe no guhindagurika gukabije no kurwanya umuvuduko, bigatuma ibikoresho byo kubaga bikora neza muri sheath.
4.Icyuma cy'imbere ni PTFE itondekanye kugirango byoroherezwe gutanga ibikoresho no kuyikuraho.Kubaka urukuta ruto rutanga ibinini binini bishoboka imbere mugihe hagabanijwe diameter yo hanze.
5.Umuyoboro wa ergonomic ukora nkigikoresho mugihe cyo gushiramo. Inkono nini yorohereza kumenyekanisha ibikoresho.
