DEVICE FOR DELIVERY OF A TOOTH WHITENING AGENT |
摘要 |
A delivery device (12, 140) includes a source (16) of pressurized fluid and a nozzle (24) which defines an outlet (22). A fluid pathway (20) fluidly connects the source of pressurized fluid with the nozzle outlet (22) for delivery of a spray of fluid from the nozzle outlet. A delivery mechanism (14) releases a dose (48) of particles (28) into the fluid pathway from an associated cart-ridge (32), such that the dose of the particles is carried by the pressurized fluid through the nozzle outlet in the spray. The particles include a dental care agent. |
