Abstract:
1. A negative pressure urine receiver comprising: a leak-proof container member; a suction part configured in said container member so as to extend outward through said container member and to be connected to a urine suction unit provided externally of said container member; a liquid-pervious sheet covering an opening of said container member wherein an amount of urine sucked into said container member through said liquid-pervious sheet under a negative pressure generated by said urine suction unit is evacuated out from said container member via said suction part under said negative pressure, wherein: said container member is a hollow structure having a length direction, a width direction and a thickness direction which are orthogonal one to another, and comprises a bottom and a peripheral wall rising in said thickness direction from said bottom so that said peripheral wall surrounds said bottom and the upper edge of said peripheral wall defines said opening, said liquid-pervious sheet covering said opening is attached to said upper edge and thereby said container member cooperates with said liquid-pervious sheet to form a urine suction space, said suction part has a urine suction port opening toward said urine suction space and a urine evacuation port opening toward the exterior of said urine suction space; a plurality of protuberances are on the bottom of said container with extending in the thickness direction so as to come in contact with said liquid-pervious sheet from below and thereby to prevent said liquid-pervious sheet from bending toward said bottom.
