A sterile disposable suction cannula is a medical device used to protect a suction catheter when suctioning body fluids or secretions from a patient's airway. The sleeve is made of a thin, flexible material designed to fit over the suction catheter and create a barrier between the catheter and the patient's airway. This helps prevent contamination and the spread of infection. Once the suction procedure is complete, the sleeve is removed and discarded without cleaning and disinfection. Sterile disposable straws are commonly used in hospitals, clinics and other medical institutions.
