Abstract
Various forms of anti-clog suction tips apparatus are disclosed. An exemplary anti-clog suction tip apparatus includes a suction tip assembly having a suction tip with a suction opening at a first end thereof for removing debris through suction, a hose attachment portion for attaching the suction tip assembly to a suction source, and an ejection wire channel. The apparatus further includes an ejection wire assembly having an ejection wire extending within the channel and an ejection button integral with or connected to the ejection wire. Applying a force to the ejection button advances the ejection wire through the channel such that an end portion of the ejection wire enters the suction tip and dislodges debris clogging the suction tip. The ejection wire may include an enlarged end portion such as, for example a ball tip. One or more of the components of the apparatus may be single-use and disposable.
