Abstract
Abstract A suction drainage control system that reduces an operator's exposure to infectious waste by permitting waste-treating material to be dispersed into a sealed chamber in which the infectious waste is contained. The sealed chamber includes a cover with a flexible liner sealed to and suspended therefrom. A reservoir having a closure is provided inside the sealed chamber for storing the waste-treating material, which reservoir is opened by manipulating the flexible liner to remove the closure.
