Abstract
Abstract An apparatus for collecting sputum including: a sputum container having an open end and a closed end; and a funnel which includes a mouth at one end and a discharge portion at the other end. The discharge portion is removably attachable to the container to establish fluid communication between the funnel and the container. A cap is provided for removably covering the container opening. Further provided is a base having a top which includes a recess for receiving the closed end of the container to support at least a portion of the container above the base and a chamber with an opening at its lower end. The cap is releasably held within the chamber with the inside of the cap facing the opening.
