Abstract
A point of use microfiltration device suitable for filtering the cooling water and cooling air supplies to a turbine driven dental handset is a multicompartmental device containing microporous filtration membranes effective to remove particulate matter, particularly microbes, thus protecting the patient from the risk of infection. The device contains passages providing for unrestricted turbine supply and return air, and may be provided with a light path suitable for use with fiber optic light supplies. The device is advantageously constructed to mate with standard multilumen and hand-piece end fittings, and may be disposed of after a single use.
