    Abstract: An otoscope suction adapter is a funnel shaped suction device that attaches to both an otoscope and suction unit in order to remove foreign objects and debris from the ear canal. The distal opening is referred to as the suction tip, which passes to a suction chamber, suction tube, and suction connector. On the posterior external aspect of the device, a point of attachment exists for the attachment of an otoscope. This allows for the transmission of light and visualization through the suction tip during suctioning procedures. The suction connector serves as a point of attachment for suction tubing and a portable or wall suction device. Emergency Room physicians affix this device to an otoscope and suction unit when attempting to remove foreign objects from a patient's ear canal. Practitioners may also use this device to remove excess ear wax and debris.
