A control device for controlling drainage of waste from a surgical stoma of a human body. The control device comprises a first cylindrical hollow body member, a drain tube extending from the first cylindrical hollow body member, a second cylindrical hollow body member rotatably coupled to the first cylindrical hollow body member and a knob configured on the second cylindrical hollow body member. The first cylindrical hollow body member comprises a skirt portion extending radially outward for being removably attached to a surface surrounding the surgical stoma of the human body. The second cylindrical hollow body member comprises an aperture configured on the second sidewall. A rotation of the knob is capable of aligning the aperture of the second cylindrical hollow body member with the drain tube of the first cylindrical hollow body member thereby forming a passage for draining the waste.
