    Abstract: In one aspect, a system for detecting blood in an oral cavity during toothbrushing is disclosed. A toothbrush includes a sensor configured to emit first light at a first wavelength and second light at a second wavelength, and receive reflected portions of the light, the reflected portions having a first intensity and a second intensity, respectively. For each of a plurality of different times of a brushing session, a processor calculates a ratio of the first intensity to the second intensity. The processor identifies peaks in the ratio over the different times and, based on the number of peaks in the ratio, determines whether hemoglobin is present in the oral cavity.

    Abstract: An oral care implement comprises a handle having a container containing oral care fluid, A head includes tooth cleaning elements and a fluid outlet to output fluid into the vicinity thereof. A manually actuatable pump mechanism in the handle between the container and fluid outlet is connected thereto by respective first and second conduits. The pump mechanism comprises a chamber having an inlet connected to the first conduit, an outlet connected to the second conduit, and an actuatable valve mechanism for selectively opening the inlet and outlet respectively to cause fluid flow into and out of the chamber. The mechanism comprises first and second valve elements and a deformable actuator connected to the first and second valve elements. A wall which defines at least a part of the chamber is adapted to be manually moved to operate the valve mechanism.

    Abstract: An oral care system including a handle and a toothbrush member and dispenser rotatably coupled to the handle. In one aspect, the toothbrush member is rotatably coupled to the handle for rotation between: (1) a first state in which the toothbrush member is positioned within the cavity; and (2) a second state in which the toothbrush member extends from the distal end of the handle. The first dispenser comprises a first store of oral care material and is rotatably coupled to the handle for rotation between: (1) a first state in which the first dispenser is positioned within the cavity; and (2) a second state in which the first dispenser extends from the distal end of the handle. In another aspect, the invention can be an oral care system comprising first and second dispensers and a toothbrush member rotatably coupled to a handle.

    Abstract: A fluid dispensing oral care implement having a low profile pump includes a head, a reservoir for storing an oral care fluid, at least one liquid outlet in the head, and a pump. The pump includes a flexible membrane movable between alternating pump intake and discharge motions. The pump includes inlet and outlet flap valves, which may be formed integrally from portions of the membrane. In one embodiment, the valves are integrally formed in the membrane as flexible cantilevered tabs movable between open and closed positions. In some embodiments, the pump may be mounted in the toothbrush head or forms the head. In some embodiments, the pump may be disposed in a neck or a handle portion of the toothbrush.
