The John Bunn Jackson Trach Plugs by Graham Field are precision-engineered medical accessories used during the "weaning" or decannulation process. These plugs are designed to fit securely into the opening of a Jackson-style tracheostomy tube, forcing the patient to breathe through their upper airway (nose and mouth). This process helps evaluate the patient's ability to breathe independently before the tracheostomy tube is permanently removed. Made from high-quality, medical-grade materials, these plugs are durable and easy to clean for repeated clinical use.
