Combined sump drainage and irrigation device

DETAILED DESCRIPTION OF THE INVENTION Referring now more specifically to the drawings, the numeral 10 generally designates the drainage and irrigation device of the instant invention.
The device 10 comprises an elongated flexible tube structure referred to in general by the reference numeral 12 and the tube structure 12 defines a plurality of individual passages 14, 16 and 18 extending longitudinally therethrough.
The passage 14 comprises an injection passage, the passage 16 comprises a suction passage and the passage 18 comprises a vent passage 18.
A first set of ends of the injection, suction and vent passages 14, 16 and 18 open separately outwardly of the tube structure 12 as at 20, 22 and 24, respectively, and include adapter end portions 26, 28 and 30 for removable connection to a vent discharge assembly (not shown), a source of vacuum (not shown) and a source of injection fluid (not shown) under pressure.
The tube structure 12 also includes an outer inflatable bladder 32 surrounding the tube structure 12 and the latter additionally includes an inflation passage 34 extending longitudinally of the tube section and opening into the bladder 32 at one end.
The bladder 32 is disposed centrally intermediate the opposite ends of the tube structure 12 and the end of the inflation passage 34 remote from bladder 32 opens outwardly of the tube structure 12 as at 36 for operative communication with a source (not shown) of fluid under pressure for inflating the bladder 32.
The end portion of the tube structure 12 on the side of the bladder 32 remote from the adapter end portions 26, 28 and 30 defines an outer tubular jacket 38 enclosing and defining the corresponding end of the air vent passage 18.
Corresponding end portions of the injection and suction passages 14 and 16 are defined by separate tube sections 40 and 42, respectively, enclosed within the outer jacket 38 and extending longitudinally thereof.
The end of the tube section 42 remote from the bladder 32 includes an end wall 44 integral with the corresponding end of the outer tubular jacket 38 and a plurality of radial bores 46 opening outwardly of the interior of the tube section 42 into the interior of the tubular jacket 38
