Abstract:
The present invention provides a dental handpiece filter unit containing a filter that minimizes the exposure of patients to pathogens found in the dental water supply lines while promoting frequent replacement of DUWL filters by providing a disposable microfiltration filter that is easily replaced at low cost. A disk or membrane type filter is placed in a disconnectable autoclavable filter unit in the handle of an existing design dental instrument such that the form and function of the dental instrument are not adversely affected. The handpiece filter unit, which fits in-line between the dental unit and the water line fitting, includes a waterline connector, a filter-housing unit, and a handpiece connector. Each of these components is connected to each other via plastic tubing. Specifically, the air and exhaust lines run from the waterline connector to the handpiece connector, circumventing the filter unit.
