摘要： An infusion set for an intermittent or continuous administration of a therapeutical substance, such as insulin, comprises a cannula housing (1) with a soft plastic cannula (2) to be placed inside the body of a patient, where the cannula together with the cannula housing (1) form a through passageway the inlet of which into the cannula housing (1) is covered by a membrane. The infusion set comprises furthermore a needle hub (3) with a needle to be inserted in the through passageway of the cannula housing through the membrane. The infusion set comprises guide means for centering the needle relative to the membrane and the through passageway, as well as locking means (31, 32) for releasably interlocking the cannula housing (1) and the needle hub (3). In the assembled state the cannula housing (1) and the needle hub (3, 41) present a substantially planar rear side (6) and a relatively large width in a direction-parallel thereto and substantially perpendicular to the longitudinal central axis of the through passageway. The guide means are co-operating guide pins and guide openings on each side of the needle and the through passageway, and the locking means are resilient locking pins (31, 32) arranged on their respective side of the needle on the needle hub (3) and comprising barbs (33, 34), said locking pins with barbs being adapted to be received in their respective recess in the cannula housing (1), where said recesses comprise shoulders (25, 26) mating said barbs (33, 34).
