Claim 9

The surgical drain of claim 1 wherein said distal end of said catheter body has a series of holes in each of the triple lumens, said holes serving to soften said distal end as well as to interconnect each of the lumens to each other and to the exterior of the catheter for improved drainage and suction.

Claim 10

The surgical drain of claim 8 wherein said distal end of said catheter body has a filamentous or porous structure which serves to soften said distal end.

Claim 11

The surgical drain of claim 1 wherein said softened portion of the distal end comprises a softer piece attached to said distal end.

Claim 12

The surgical drain of claim 1 wherein a radiopaque strip is located along a portion of the length of said catheter body.

Claim 14

A surgical drain comprising, in combination, a triple lumen catheter body having distal and proximal ends, a connector on the proximal end of the catheter body, a suction port, irrigation port and air intake port in said connector, attached plugs on said connector for closing at least said irrigation port and said air intake port, the distal end of said catheter body being formed with a series of openings in each of the lumens therein, at least the distal end of the catheter body being readily flexed as the catheter body is pushed against body tissues to reduce pressure necrosis of the surrounding tissues.

Claim 15

A surgical drain comprising, in combination, a triple lumen catheter body having distal and proximal ends, a connector on the proximal end of the catheter body, a suction port, irrigation port and air intake port in said connector, attached plugs on said connector for closing at least said irrigation port and said air intake port, the distal end of said catheter body being formed with a series of openings in each of the lumens therein, at least the distal end of the catheter body being readily flexed as the catheter body is pushed against body tissues to reduce pressure necrosis of the surrounding tissues.

Claim 16

A surgical drain according to claim 13 and further including a suturing means on said catheter body as a stabilizing anchor for the drain.

Claim 17

A surgical drain comprising, in combination, a catheter body having three lumens therein, openings in at least one of said lumens in the distal end of the catheter body, a connector on the proximal end of said catheter body, the connector having passageways therein in communication with the lumens in the catheter body, the proximal end of the connector having suction, irrigation and air intake ports, the irrigation and air intake ports being spaced from the suction port, a radiopaque stripe located along a portion of the length of the catheter body, at least the distal end of the catheter body being readily bendable as the catheter body is pushed against body tissues to reduce pressure necrosis of the surrounding tissues.

Claim 18

A surgical drain comprising, in combination, a catheter body having three lumens therein, openings in at least one of said lumens in the distal end of the catheter body, a connector on the proximal end of said catheter body, the connector having passageways therein in communication with the lumens in the catheter body, the proximal end of the connector having suction, irrigation and air intake ports, the irrigation and air intake ports being spaced from the suction port, a radiopaque stripe located along a portion of the length of the catheter body, at least the distal end of the catheter body being readily bendable as the catheter body is pushed against body tissues to reduce pressure necrosis of the surrounding tissues.

Claim 19

A surgical drain according to claim 15 and further including plugs for at least the irrigation and air intake ports, said plugs being attached to the connector.

Claim 20

A surgical drain according to claim 15 and further including a suturing means mounted on said catheter body.

Claim 21

A surgical drain according to claim 15 and further including a filter means on said air intake port.

Claim 22

A surgical drain according to claim 15 wherein the openings in the lumens in the distal end of the catheter body are in each of said lumens and interconnect the lumens for improved drainage and suction.

Claim 23

A sump drain comprising: (a) an integral extruded catheter having distal and proximal ends and comprising: (i) a first lumen for the drainage of body fluids by suction; (ii) a second lumen for the passage of filtered air; (iii) a third lumen for the passage of irrigation fluid, said first, second and third lumens extending parallel to each other along the major portion of the longitudinal length of the catheter; (iv) a funnel portion at its proximal end, said funnel portion having a connector receiving port extending from the first lumen, a filtered air intake port extending from the second lumen, and an irrigation port extending from the third lumen; (v) holes at its distal end, said holes connecting each of the first, second, and third lumens to the exterior of the catheter; (b) means for closing the irrigation port; (c) a connector, said connector being arranged and constructed so that fluid may pass from the first lumen through the connector, said connector having a proximal end including a suction port; (d) means for closing the suction port of the connector; (e) a bacteria filter, said bacteria filter having means for filtering bacteria from air and being arranged and constructed so that air may pass through the bacteria filter and into the second lumen, said bacteria filter having a bacteria filter air intake port for the intake of air; (f) means for closing the bacteria filter air intake port; and (g) a collar slidably disposed about the catheter.

Claim 24

A sump drain comprising: (a) an integral extruded catheter having distal and proximal ends and comprising: (i) a first lumen for the drainage of body fluids by suction; (ii) a second lumen for the passage of filtered air; (iii) a third lumen for the passage of irrigation fluid, said first, second and third lumens extending parallel to each other along the major portion of the longitudinal length of the catheter; (iv) a funnel portion at its proximal end, said funnel portion having a connector receiving port extending from the first lumen, a filtered air intake port extending from the second lumen, and an irrigation port extending from the third lumen; (v) holes at its distal end, said holes connecting each of the first, second, and third lumens to the exterior of the catheter; (b) means for closing the irrigation port; (c) a connector, said connector being arranged and constructed so that fluid may pass from the first lumen through the connector, said connector having a proximal end including a suction port; (d) means for closing the suction port of the connector; (e) a bacteria filter, said bacteria filter having means for filtering bacteria from air and being arranged and constructed so that air may pass through the bacteria filter and into the second lumen, said bacteria filter having a bacteria filter air intake port for the intake of air; (f) means for closing the bacteria filter air intake port; and (g) a collar slidably disposed about the catheter.
