Containers used to retrieve sputum samples from patients for diagnostic testing (e.g., sputum culture, Gram stain, acid-fast bacilli identification). They are typically constructed of plastic and are packaged as single-use sterile items. Some sputum collectors are designed to capture a sputum specimen directly from a patient with a productive cough; others are designed to be attached to a suction catheter for collecting sputum via an endotracheal tube.
