A phlegm suction machine is different medical equipment used to assist in the removal of mucus and secretions in the respiratory tracts. It operates on the principle of drawing normal vacuum in the breathing system with the help of a tube and a container to collect the sputum. Chest drum suction can be used in hospitals and in cases where patients have some health issues such as chronic bronchitis, cystic fibrosis or COPD that would make them unable to clean their airways adequately. It enhances the breathing system and minimizes the possibilities of coming up with an infection.
