Abstract

A surgical irrigator for wounds which delivers a flushing solution to a wound, the irrigator includes first and second elongated concentric tubes, the first outer tube being connected to a solution supply and the second inner tube being connected to a solution suction, said tubes having substantially conjunctive terminating open ends, said outer tube having an orifice configuration with a plurality of apertures arranged around a central orifice of the inner tube, the outer tube being telescopically moveable relative to the inner tube.

Claims

1. A medical irrigator for flushing wounds with a liquid comprising:

a. a first conduit having a first terminal open end and a second end having means for connecting said second end to a liquid supply means for delivering liquid to said first conduit;

b. a second conduit having a first terminal open end and a second end having means for connecting said second end to a liquid suction means for removing liquid from said conduit, said second conduit positioned within said first conduit and displaced from said first conduit, wherein said terminal end of said first conduit has a scalloped edge that is inwardly pinned against the outer surface of said second conduit forming a plurality of apertures therebetween.

2. The irrigator of claim 1 wherein said first conduit is tubular and said second conduit is tubular and is positioned concentrically within and displaced from said first conduit.

3. The irrigator of claim 2 wherein said means for connecting said second end of saiD first conduit comprises a tubular connecting branch arm with a flared end, and said means for connecting said second end of said second conduit comprise flared tubular end, said flared tubular ends being adapted to connect to flexible hoses.

4. The irrigator of claim 3 whereas said terminal open end of said first conduit is telescopically adjustable with said terminal open end of said second conduit.

5. The irrigator of claim 4 wherein said terminal open end of said first conduit includes a plurality of apertures arranged symmetrically around the first conduit.
