Abstract
Abstract A drainage device for irrigation of the ear comprises a receptacle of clear flexible plastic which has an inner wall formed with an opening through which the outer ear projects, thereby aiding in positioning and supporting the same. A band or tie strings on the upper edge of the inner receptacle wall embraces the patient's head and supports the weight of the receptacle. From the bottom of the receptacle extends a drainage tube which can be conveniently clipped to the patient's garment. To enable the receptacle to fit in leak-proof manner, surgical appliance adhesive secures the receptacle around the front and lower part of the outer ear.
