Abstract:

The covered yankauer suction device includes a yankauer having a suction tip at a first end and a connector at a second end. A retractable sleeve partially encloses the yankauer. One end of the retractable sleeve is secured to the yankauer while the opposite end of the retractable sleeve is secured to a valve. The valve includes a cross-cut that enables the valve to open when the suction tip of the yankauer pushes against the underside of the cross-cut.
