<p>A catheter inserter has an inserter housing (12) with a flat base and a cannula housing (14) disposed within the inserter housing with a cannula (20) extending generally parallel to the inserter housing longitudinal axis. Stop means (36-42,48,50) are dispersed at each end of the inserter housing. Locking means (50) on the cannula housing selectively engage the stop means to lock the cannula housing in a first disposition in which the cannula extends outwardly from the inserter housing and in a second disposition in which the cannula is retracted within said inserter housing. The cannula housing has a passage in fluid communication with the cannula which, together with means (26,28) on the inserter housing and cannula housing, permit the external viewing of blood passing into the fluid passage from the cannula.</p> |
