ABSTRACT:
A urine drainage tap is provided which includes an elongated passage having a barrel disposed therein and a control member located in the barrel which is moveable in relation to the barrel for defining an open and closed position. The lever arm is connected to the control member to permit movement of the control member. In an important aspect of this invention, the lever arm is moveable so as to extend along the passage in substantially opposite longitudinal directions relative to the passage when the control member is in the open and closed positions so as to avoid the tendency for the patient to inadvertently open or close the control member by leaning on the lever arm.
