Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
173 words
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.
Claim 2
Dependent Claim
173 words
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.
Claim 3
Dependent Claim
127 words
A device according to claim 1 wherein said manually operable valve means comprises a radially symmetrical fluid conductive stem and a mating hollow valve seat in which said stem may be manually rotated about its axis of symmetry, said stem being attached to and in open communication with said syringe and further having at least one radially disposed aperture through which fluid may be transported into and out of said syringe, and said valve seat having a radially disposed first port in communication with said first arm segment and a radially disposed second port in communication with said second fluid conduit, said first port and said second port being additionally so disposed as to alternately be in opposition to and communication with a one of said apertures.
Claim 4
Dependent Claim
27 words
A device according to claim 2 wherein said stem may be rotated relative to said valve seat by the rotation of said syringe relative to said manifold.
Claim 5
Dependent Claim
28 words
A device according to claim 3 wherein said axis of symmetry of said stem is disposed substantially orthogonal to said first arm segment and said second arm segment.
Claim 6
Dependent Claim
14 words
A device according to claim 4 wherein said syringe is a manually compressible bulb.
