Abstract
A medical lavage apparatus (10) for body cavities comprising a housing (20) having parallel irrigation and aspiration cylinders (28, 32) with captive plungers (24, 26) extending in bores thereof from a first end and pairs of check-valves (102, 106) positioned in parallel, smaller, offset cylinders located at second ends such that reciprocal movement of each plunger in each cylinder performs the function of a one-way pump. The plungers are held captive and aligned by guide-stops (90') proximally disposed in each cylinder. Each plunger comprises a seal (80) disposed at the distal end thereof which inhibits communication between the pairs of check-valves in each cylinder when the plunger is fully seated in the cylinder. Novel jam-free dome shaped, slit check-valves (230) are disposed to be the pair of check-valves in the aspiration cylinder in one embodiment and in irrigation cylinders as well in other embodiments. The dome shaped valves are described for use in other medical fluid control applications, as well. A septum (50) formed of intersecting semi-circular-in-cross-section baffles (58, 60) joins the adjacent outer ends of the irrigation and aspiration check-valve cylinders so as to allow full fluid streams flowing from these outer ends to flow together at an angle. The septum and associated irrigation and aspiration check-valve cylinders are enclosed in a common exchange tube (22) which leads to a common patient tube connecting nozzle. A special patient tube securing attachment (97') is disposed on the connecting nozzle.
