A washable pouch which enables accumulating solid waste and also to drain and wash it when the pouch is filled. The washable pouch has an abdominal inlet, a draining outlet and a washing inlet. The washable pouch has a flat structure constructed of two planar sheets of flexible material, which are fused together at their margins all along their perimeter except for inlet and outlet openings. Both washing inlet and draining outlet have funnel shapes with seals which can block all flows when closed. The washing inlet which is installed at the pouchs top can be used to expel gasses and also to have an air filter. The washing inlets funnel shape facilitates pouring water into the pouch, thus liquefying the solid waste and enabling easier draining. The abdominal inlet is surrounded by an adhesive layer which has tapered boundary thereby reducing abdominal skin irritation.
