A needle assembly has a needle hub that has a body to which are formed two plates at opposite sides thereof in a parallel relationship. The plates have respective upper edges and lower edges that lie substantially along respective planes, so that the needle hub may be stably placed onto a surface by means of the respective edges. The plates also prevent the rolling of the needle between the fingers of the clinician when the clinician holds the needle assembly by means of the plates. A partition is formed orthogonally proximate to the front ends of the parallel plates. The upper edge of the partition lies co-planarly along the same plane as the respective upper edges of the plates, while the lower edge of the partition lies co-planarly along the same plane where the respective lower edges of the plates lie. The partition and the parallel plates together provide upper and lower three point stable supports for the needle hub. A notch at the partition provides a guided line of sight to the tip of the needle for the user. The connector at the proximal portion of the needle hub is configured to have a non-conventional configuration that allows it to mate only with a counterpart connector that has a complementary non-conventional configuration.一種注射針總成,其具有一注射針轂部,該注射針轂部具有一主體,兩個板以一平行關係形成於該主體之對邊上。該等板具有大體上沿各別平面定位之各別上邊緣及下邊緣,以便可藉助於該等各別邊緣將該注射針轂部穩定置放於一表面上。當臨床醫師藉助於該等板握持該注射針總成時,該等板亦防止該注射針於該臨床醫師之手指之間的滾動。一隔板緊鄰該等平行板之前端垂直形成。該隔板之上邊緣沿與該等板之該等各別上邊緣相同之平面共面地定位,而該隔板之下邊緣沿該等板之該等各別下邊緣所處之相同平面共面地定位。該隔板及該等平行板共同為該注射針轂部提供上下三點穩定支撐。該隔板處之一凹口為使用者提供向該注射針尖端之一視線導引線。該注射針轂部之該近端部分處之連接體經配置以具有一非習知構造,該非習知構造允許該連接體僅與一具有互補非習知構造之配對連接體配合。
