DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a valve for urine drainage applications, particularly for a urostomy pouch.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a valve which is easy end intuitive to use and which can be made substantially leak-free on a production basis.
From one aspect, the invention provides a valve for urine drainage applications having a valve housing for attachment to a urine receptacle and a valve member rotatable within the valve housing between an open position, in which liquid can flow from the receptacle along an angled path to the outlet from the valve, and a closed position cutting off the liquid flow, wherein the valve member can rotate about an axis substantially normal to the direction of liquid outflow from the valve when the valve member is rotated to the open position and wherein a manually operable means for rotating the valve member in the housing is arranged to point in the direction of the flow from the valve when the valve member is in the open position. Preferably, the valve is mounted on the receptacle so that the direction of liquid outflow is downwards when the receptacle is being worn in use.
From another aspect, the invention provides a valve for a urostomy pouch, comprising a body member and a valve member, the body member having an attachment surface for attaching to a wall of the pouch, and a housing containing a cylindrical bore for receiving the valve member and which communicates with the pouch via an aperture in the attachment surface, said housing also having an outlet, and said valve member comprising a cylinder having a manually operable handle extending therefrom, whereby said valve member can be rotated from an open position, in which the handle points in the same direction as the outlet, and in which position liquid from the pouch can flow through an angled path from the aperture into the bore and a further angled path from the bore to the outlet; to a closed position, in which the handle points away from the outlet, and the valve member seals the outlet from the aperture.
The attachment surface may be formed by one side of a plate-like member which carries the housing an its other side. Advantageously, the housing is substantially cylindrical and is closed at one end where the aperture is located and open at the other end where the handle of the valve member protrudes.
The cutlet preferably comprise a tube pointing downwards when the pouch is being worn and forms a T-shape in conjunction with the housing.
The up ad down operating movement of the handle is more ergonomic than the sideways operation of valves in current use. Also, a downward movement of the handle intuitively indicates to the patient opening of the valve, whilst upward movement intuitively indicates closing, even when this valve is in such a position that it is beyond the patient's line at sight.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described by way of example with reference to the accompanying drawings, in which:
FIG. 1 is a front perspective view of one embodiment of the valve housing or body member;
FIG. 2 is a rear perspective view of the valve housing or body member shown in FIG. 1;
FIG. 3 is a perspective view of one embodiment of the valve member for cooperation with the valve housing or body member; and
FIG. 4 is a perspective view of a valve assembled from the members shown in FIGS. 1 to 3.
DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings, the valve housing or body member generally indicated at 1 includes a substantially rectangular attachment plate 2 having a surface 2a which can be sealed on to the side wall of a urostomy pouch 13 indicated in broken lines in FIGS. 1 and 4. The attachment plate 2 carries a substantially cylindrical housing 3 which is open at one end and closed at the other end. Adjacent the closed end of the housing 3, an inlet aperture 4 in the plate 2 allows communication between the interior of the housing and the pouch. A slot 5 is provided in the wall of the housing 3 a
