Oral suction device

Abstract

To allow a vacuum tip and a vacuum hose to be attached to and detached from each other in a physical manner in a case of installing a light source on the vacuum tip side, it is configured that electrical connection between the vacuum tip and the vacuum hose is established in association with the attachment and detachment. An oral suction device including a vacuum hose connected to a suction source and a vacuum tip having a tube body that has a proximal end connectable to a distal end of the vacuum hose and a distal end as a suction port, includes a light source provided in the vacuum tip to illuminate inside of an oral cavity, a hose-side electrode, provided at the distal end of the vacuum hose, for supplying power from a power supply to the light source, and a tip-side electrode, provided at the proximal end of the vacuum tip and electrically connected to the light source, for receiving the power from the hose-side electrode.
