The D Fend Pro Water Trap is a medical device used in respiratory care settings, particularly in conjunction with ventilators and anesthesia machines. Its primary function is to help prevent the entry of water and other contaminants into the respiratory circuit during mechanical ventilation. This is positioned in the patient's exhalation circuit, between the patient and the mechanical ventilation equipment. Its main purpose is to protect the equipment from exposure to moisture and contaminants. The water trap typically has a transparent housing that allows healthcare providers to monitor the presence of moisture or any visible contaminants within the trap. D Fend Pro Water Trap can be used in a variety of clinical settings where mechanical ventilation is required, including operating rooms, intensive care units, and emergency departments.
