Abstract:
The present invention relates to a dental instrument contamination prevention unit, a dental treatment instrument having same, and a cleaning liquid supply apparatus. The dental instrument contamination prevention unit comprises: a fixed frame installed on a flow path through which a cleaning liquid is supplied from a cleaning liquid supply apparatus to an injection hole formed in a dental treatment instrument drawn into a patient's mouth so that the cleaning liquid can be injected into the patient's oral cavity through the injection hole; and an opening/closing part, installed in the fixed frame, for closing the flow path when the supply of the cleaning liquid from the cleaning liquid supply apparatus is interrupted, in order to prevent foreign matter in the patient's oral cavity from being sucked through the injection hole by the negative pressure generated when the supply of the cleaning liquid is interrupted from the cleaning liquid supply apparatus, and thus contaminating the cleaning liquid supply apparatus. The dental instrument contamination prevention unit, the dental treatment instrument having same, and the cleaning liquid supply apparatus, according to the present invention, have the advantage in that when the supply of the cleaning liquid is interrupted from the cleaning liquid supply apparatus, the flow path through which the cleaning liquid is supplied to the injection hole of the dental treatment instrument is blocked and foreign matter in the oral cavity is prevented from flowing into a handpiece, thereby preventing the handpiece from being contaminated.
