Abstract: A delivery device (12) includes a source (16) of pressurized fluid, a nozzle (24, 16) which defines an outlet (22), a pathway (20) which fluidly connects the source of pressurized fluid with the nozzle outlet (22) for delivery of a spray of fluid from the nozzle outlet, and a receptacle (32), which receives a dose of particles (28). The receptacle is positioned in the pathway such that the dose of the particles is carried by the pressurized fluid and through the nozzle outlet, the particles including a tooth whitening agent.

Abstract: An ultrasound probe (100) is disclosed comprising a probe body (120) having a mounting area (121) and a flexible lip (123) around said mounting area for sealing a space (110) between the mounting area and a subject (1) contacted by the ultrasound probe; and a plurality of ultrasound transducer elements (130) mounted in the mounting area. The probe body further comprises an inlet (125) to said space and an outlet (127) from said space for facilitating a fluid flow through said space when sealed. Also disclosed are an ultrasound system (10) comprising such an ultrasound probe (100) and a method (200) of subjecting a subject to ultrasound waves generated with such an ultrasound probe (100).

Abstract: The appliance includes a brushhead having conductive fiber bristles by which a potential is applied to electrochemically activate a teeth whitening substance, such as peroxide, in the vicinity of the teeth. An impedance appliance system (62) or an optical appliance system (27) provides information concerning whether the conductive fiber bristles are adjacent a tooth surface or gum region. The impedance system uses an electrical signal through the fiber to determine the impedance of a circuit which includes the tooth or gum surface, the impedance being different, depending on whether a tooth or gum surface is in the circuit. The optical system generates a light beam which is directed to the mouth surface through a conductive fiber, the color of the returning light indicating whether the surface is a tooth or gum region. If a tooth is determined, the teeth whitening substance is activated at that bristle, while if gum tissue is determined, the teeth whitening substance is not activated at that bristle.

Abstract translation: 该器具包括具有导电纤维刷毛的刷头，通过该刷头施加电位以电化学地激活牙齿附近的牙齿美白物质，例如过氧化物。 阻抗器具系统（62）或光学器具系统（27）提供关于导电纤维刷毛是否邻近牙齿表面或牙龈区域的信息。 阻抗系统使用通过光纤的电信号来确定包括牙齿或牙龈表面的电路的阻抗，阻抗是不同的，这取决于牙齿或牙龈表面是否在电路中。 光学系统产生通过导电纤维指向口表面的光束，返回光的颜色表示表面是牙齿或牙龈区域。 如果确定牙齿，牙齿美白物质在该刷毛处被活化，而如果确定牙龈组织，那么该牙齿美白物质在那根毛上不被激活。
