1. A closure device, comprising:
- a housing, a first hose, a second hose, a first cylindrical nozzle secured to said housing for connection to said first hose and a second cylindrical nozzle secured to said housing for connection to said second hose, said first and second nozzles extending from said housing in a substantially parallel, side-by-side relationship; and
a moving closure piece rotatably connected to said housing about said first nozzle, and including a slot in a form of a circular arc extending from a first slot end to a recess of a dimension that is not less than an outside diameter of said second hose, wherein said first slot end has a reduced width for completely pinching said second hose and preventing fluid flow, and wherein said recess forms a second slot end.

Abstract
The invention relates to a closure device for closing a hose by pinching, and in particular for closing a flexible tube or hose used in the medical field. Essentially, the device comprises a closure piece (62) provided with a circularly arcuate slot (70) which is extended by a circular orifice (76). The closure piece (62) can be rotated about a point O on a circle of radius (R) equal to the radius of the slot (70).

6. A closure device comprising:
-
a housing, a first hose, a second hose, a first cylindrical nozzle secured to said housing for connection to said first hose and a second cylindrical nozzle secured to said housing for connection to said second hose, said first and second nozzles having nozzle axes that are substantially parallel to one another;
a moving closure piece rotatably connected to said housing and including a slot in a form of a circular arc extending from a first slot end to a recess of a dimension that is not less than an outside diameter of said second hose, wherein said first slot end has a reduced width for completely pinching said second hose and preventing fluid flow, said recess forming a second slot end, said closure piece including an arc-shaped plate defined by an inner circular edge and an outer circular edge and having a first end associated with said first slot end and a second end associated with said recess;
an arm having a first end pivotally mounted to said housing about an axis of rotation substantially parallel to said nozzle axes and a second end connected to said moving closure piece on said arc-shaped plate;
a first cylindrical sleeve cooperatively arranged with said first cylindrical nozzle to hold said first hose in a removable manner;
a second cylindrical sleeve cooperatively arranged with said second cylindrical nozzle to hold said second hose in a removable manner; and
a holding member having a first end and a second end, wherein at least one of said ends of said holding member is attached to said second cylindrical sleeve, said holding member being constructed to prevent said second hose from moving while said closure piece is being moved from its first position to its second position.

7. A closure device for an outlet hose, comprising:
-
a housing, an inlet hose, a first cylindrical nozzle secured to said housing for connection to said inlet hose and a second nozzle secured to said housing for connection to said outlet hose, said nozzles having axes that are substantially parallel, said nozzles extending in substantially the same direction from the housing in a substantially side-by-side relationship;
a moving closure piece rotatably mounted about said first nozzle and having a rotation axis substantially parallel to said nozzle axes, said closure piece including a slot in a form of a circular arc substantially centered on said axis of said first nozzle, said slot having a first end and a second end, said second end being connected to a recess of a dimension that is not less than an outside diameter of the outlet hose, said slot having in the vicinity of its first end a width that is suitable for completely pinching said outlet hose and preventing fluid flow, the second end of the slot having a width that flares to connect with said recess;
means for guiding said closure piece in rotation about said rotation axis, said guiding means being connected to said first nozzle and comprising an arm having a first end which is rotatably mounted about said first nozzle and a second end which is connected to said closure piece; and
means for rotating said closure piece between a first position in which said outlet hose passes freely through said recess of the closure piece and a second position in which said outlet hose is pinched in the first end of said slot. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A closure device for an outlet hose comprising:
-
a housing, an inlet hose, a first cylindrical nozzle secured to said housing for connection to said inlet hose and a second nozzle secured to said housing for connection to said outlet hose, said nozzles having axes that are substantially parallel;
a moving closure piece rotatably mounted about said first nozzle and having a rotation axis substantially parallel to said nozzle axes, said closure piece including a slot in a form of a circular arc substantially centered on said axis of said first nozzle, said slot having a first end and a second end, said second end being connected to a recess of a dimension that is not less than an outside diameter of the outlet hose, said slot having in the vicinity of its first end a width that is suitable for completely pinching said outlet hose and preventing fluid flow, the second end of the slot having a width that flares to connect with said recess, said closure piece further including a plate in a form of a circular arc defined by an inner circular edge and an outer circular edge and having a first end corresponding to the first end of said slot, a second end corresponding to said recess and an arm having a first end rotatably mounted about said first nozzle and a second end connected to one end of said plate;
means for guiding said closure piece in rotation about said rotation axis, said guiding means being connected to said first nozzle, said guiding means comprising a second plate secured to said second nozzle and having an orifice of a diameter slightly greater than an outside diameter of said outlet hose, said second plate being disposed in a plane generally orthogonal to an axis of said outlet hose;
means for rotating said closure piece between a first position in which the outlet hose passes freely through said recess of the closure piece and a second position in which the outlet hose is pinched in the first end of said slot; and
a holding member offset axially relative to said second plate and being secured to said second plate in such a manner that said closure piece can move between said second plate and said holding member, said holding member being substantially in contact with said outlet hose and being constructed to prevent said outlet hose from moving while said closure piece is being moved from its first position to its second position. - View Dependent Claims (15, 16, 17, 18, 19, 20)
