Abstract
A medical irrigation device includes means for connecting a bulb-type syringe to a cannula such as a resectoscope so that fluid may be circulated therethrough in either direction and selectively either by a direct path therebetween or by a circuitous path including a specimen collecting receptacle whereby lavage may be accomplished with rapid reversal of fluid flow direction yet with periodic removal of particulate matter from the circulating fluid.
Claims5
A medical irrigation device for alternately introducing fluid into and withdrawing fluid from a body cavity through a cannula, said device comprising in combination:
- a fluid receptive manually operable syringe;
- a specimen collecting receptacle;
- a fluid conductive manifold including a fluid conductive first arm segment, and a bifurcated fluid conductive second arm segment connected substantially orthogonally thereto, said first arm segment including means for providing connection to and establishing open communication with said cannula, and said second arm segment including means for providing connection to and establishing open communication with said specimen collecting receptacle;
- said second arm segment comprising a first fluid conduit and a second fluid conduit, said first fluid conduit being between and in open communication with said first arm segment and said specimen collecting receptacle and said second fluid conduit communicating with said specimen collecting receptacle through a particulate filter means;
- and
- a manually operable valve means for controllably establishing open communication alternatively between said syringe and said first arm segment and between said syringe and said second fluid conduit.
