摘要

A device (1) for preventing the growth of the bacteria or removing the bacteria bred on the inner wall surfaces of the ducts (8, 9, 10) of a dental unit, comprising a transponder (3) having a control unit (2) generating electric signals including audible frequency components, a coil (3a), and a case (3b) for storing the coil (3a) and mounting means (5) for mounting the transponder (3) on the outer wall surface of the duct (8), whereby an audible frequency electric signal allowed to transmit through the ducts (8, 9, 10) is generated by applying the electric signals to the coil (3a).
