Abstract
Abstract An ileostomy valve comprising an attachment plate having a central opening passing therethrough which communicates with a support housing is shown. The support housing has an elongated central member which defines a passageway which communicates with the opening in the attachment plate and which terminates at the remote end of the elongated second member. A cover plate has a central drainage opening extending therethrough. The cover plate is positioned contiguous the attachment plate positioning the coacting member to engage and coact with the attachment plate. An elongated flexible tubing member extends through the central drainage opening in the covering plate, through the opening in the attachment plate, through the passageway in the elongated central member to the second opening in the elongated central member. The other end of the tubing member is affixed to the remote end of the elongated central member defining an unobstructed drainage passageway extending through the elongated central member to the cover plate. When the cover plate is rotated in a selected direction at least 360 degrees relative to the attachment plate, the coacting member coacts with the attachment plate twisting the tubing member to obstruct and close the same to define an obstructed drainage passageway or selectively rotating the cover plate at least 360 degrees, or the same number of degrees used to twist the elongated flexible tubing member to close the same, in a direction opposite to the selected direction to open the drainage passageway.
