Vacuum suction type urinating aid

Claim 1

A vacuum suction type urinating aid comprising: a urine receiver having a urine suction opening adapted to be applied to the urinating region of a subject to receive therefrom urine and a urine outlet; a urine tank; a urine transport tube connected between said urine outlet and said urine tank; and vacuum suction device means connected to said urine tank for creating a vacuum to form an air current drawing any urine in said urine receiver through said urine transport tube into said urine tank, said vacuum suction device means comprising: a casing having at opposite ends thereof an inlet connected to said urine tank for receiving said air current and an outlet for discharging said air current; said casing being formed by two casing halves divided longitudinally of said opposite ends; each said casing half having formed internally thereof a plurality of transversely extending, longitudinally spaced grooves, each said groove being defined by a pair of transversely extending, longitudinally spaced protrusions extending inwardly from the respective said casing half; a suction motor including an impeller for creating said air current; a partition and support plate supporting said motor, said partition and support plate fitting within respective said grooves in said casing halves with said casing halves joined together, such that an air passage extends through said casing from said inlet, through said impeller to said outlet; a first plurality of silencing partition plates fitting within respective said grooves of said casing halves between said inlet and said impeller; a second plurality of silencing partition plates fitting within respective said grooves of said casing halves between said impeller and said outlet; and said silencing plates altering the direction of said air passage and diverting the path of said air current through said casing, thereby reducing the level of noise generated from said vacuum suction device means.
