An improved medical lavage apparatus (10) includes guide/lock/stop tabs (122) which are inserted through a medical la- vage syringe housing (20) into irrigation and aspiration bores (30, 34) thereof for engaging longitudinal ribs (68a-d, 69a-d) of irri- gation and aspiration plungers (24, 26) to prevent their rotation and a circumferential latch rib (134a) of the aspiration plunger for locking the aspiration plunger in an inserted position. The tabs also contact end circumferential ribs (70') of the plungers for providing stops to prevent the plungers from being removed from their respective bores. The tabs comprise two legs (126) which straddle the longitudinal ribs, with a longitudinal rib (68a) of the aspiration plunger having a notch (140) at the tab in the aspira- tion bore to allow rotation of the aspiration plunger when it is in the inserted position for engaging the legs with the circumferen- tial latch rib.
