摘要:
A oral irrigator device (10) for cleaning teeth, including a system (14) for producing a stream of liquid/air bursts and a nozzle (16) connected to the system, and through which the stream of liquid/air bursts are directed. The nozzle can include a guidance tip (26) including a base portion (30), a tip portion (28), and an orifice (31) through which the stream of liquid/air bursts exits at a flow output pattern, and a flow output pattern selection mechanism (90, 90′) connected to or positioned within the guidance tip. A flow output pattern selection mechanism can be configured to be selectively actuated and to vary, upon the actuation the flow output pattern between a first flow output pattern to at least a second flow output pattern.
摘要:
An oral cleaning device (100) including: a nozzle portion (30) configured to direct a plurality of liquid droplets; an actuator (120); a mode selector (130); a liquid reservoir (38) wherein in operation liquid is moved from the liquid reservoir into an orifice (36) at the proximal end of the nozzle; a system (12, 13, 14, 24) configured to drive a plunger or piston element (16) toward the proximal end of the nozzle to create a spray of liquid droplets when the moving air comes into contact with the liquid; a control unit (15) configured to control the system to drive the plunger a predetermined number of times in response to a single actuation of the actuator, where the control unit is further configured to accept input from the user via the mode selector, and the mode selector is configured for the user to select a number of liquid bursts that will be delivered in response to a single actuation of the actuator.
摘要:
An oral cleaning device comprises a body which carries a set of projections. An actuator device is associated with one or more of the projections in the form of an electroactive polymer structure for adjusting a position of the associated one or more projections. This enables dynamic control of the cleaning function.

摘要:
A nozzle (12) for an oral irrigator device (10) having a guidance tip (34) with at least one orifice (36) at one end, and a nozzle spacer assembly (58) positioned around the at least one orifice (36). The at least one orifice is configured to expel a fluid as one of a jet, a spray, or any combination thereof. The nozzle spacer assembly (58) comprises at least two pairs of pliable spacers (60) that extend from the surface (35) for ensuring that the area at an entrance of an interproximal space between two teeth are treated, and (ii) establishing an improved angle of impact of the fluid expelled from the orifice.
摘要:
An apparatus comprises a sensor for measuring a physiological parameter of a subject, wherein the physiological parameter sensor is adapted to be worn by the subject; an actuator comprising an electro-active polymer material, EAP, portion for adjusting the position of the physiological parameter sensor relative to the subject; a feedback sensor for measuring movement of the physiological parameter sensor and/or the subject; a controller configured to process the measurements of the feedback sensor and to adjust the position of the actuator based on information from the feedback sensor.
