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 lowerthree 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.On décrit un ensemble aiguille qui comprend un pavillon daiguille présentant un corps sur des côtés opposés duquel sont formées deux plaques parallèles. Les plaques comprennent des bords supérieurs et inférieurs respectifs qui sétendent sensiblement le long de plans respectifs tels que le pavillon daiguille peut être placé de façon stable sur surface, au moyen des bords respectifs. Les plaques empêchent également laiguille de rouler entre les doigts du clinicien quand celui-ci tient lensemble aiguille au moyen des plaques. Une cloison présente une forme orthogonale à proximité des extrémités avant des plaques parallèles. Le bord supérieur de la cloison sétend de façon coplanaire le long du même plan que les bords supérieurs respectifs
