Abstract: A breath testing apparatus is provided with on-board “Instruction Manual” tutorials incorporated in a display device installed in the device. Alternatively, on-board instructional videos can be added to various objects or processes requiring instructions.

Abstract: An air sampling apparatus is disclosed, including a closed loop system for extracting air to be sampled into an analysis device such as a gas chromatograph, which is further coupled to an output. The closed loop sample extraction method reduces contaminants that can otherwise be introduced into air samples.

Abstract: Tooth cleaning devices. An embodiment of a tooth cleaning device includes: an elongated head sized to fit in an oral cavity. The elongated head having a first surface and a neck extending from the head. A first tooth cleaning element having a plurality of upstanding wiping members extends upward from below the first surface and extends radially outward from a center of the first tooth cleaning element. Each upstanding wiping member has a free outermost edge that extends upwards substantially from the first surface to the top of the wiping member. A plurality of upstanding arcuate shaped second tooth cleaning elements secured to the head and located outboard of the first tooth cleaning element are also provided. In addition, a plurality of upstanding third tooth cleaning elements are secured to the head and border an edge of the first surface. The third tooth cleaning elements have a circular cross-sectional area.

Abstract: Toothbrush heads, e.g., for power toothbrushes, are provided. The toothbrush heads include a support member and a plurality of bristles or tufts of bristles extending from the support member, the bristles or bristle tufts having different lengths. The contour of the bristles may be selected to allow substantially all of the bristles to contact the dentition during brushing.

Abstract: Dual valves are described herein. The dual valves have a plurality of lumens disposed within a unitary body. The dual valves can be used, for example, in personal care products such as toothbrushes and razors to dispense fluids such as dentifrice and shaving aids.

Abstract: Oral care devices are provided that include a first component and a second component removably engaged with the first component; the first and second components having a respective fluid passageway extending therethrough, the respective passageways capable of fluid communication while the first and second components are engaged; and at least one of the first and second components including a sealing member constructed to allow fluid communication between the first and second passageways when the first and second passageways are engaged and to close the associated passageway when the first and second components are disengaged. Oral care devices are also provided that include a replaceable and refillable cartridge.

Abstract: A toothbrush is disclosed. The toothbrush includes a head; a base member supported by a neck; a support member having a plurality of holes therein; a resilient cushion member disposed, at least in part, between the base member and the support member, the cushion member being fixed to the support member; at least one center bristle tuft extending from the support member; and two or more outer bristle tufts located at least partially around the at least one center bristle tuft. The center bristle tuft has a first shaped cross section and the outer bristle tufts have a second shaped cross section. The first shaped cross section is different from the second shaped cross section. Applying a force to the center bristle tuft and/or the outer bristle tufts causes the center bristle tuft and/or the outer bristle tufts to deflect into the resilient cushion member.

Abstract: An improved evacuated air chamber having a plurality of generally flat exterior walls, a closed end, and an open end wherein the open end is provided with a resealable stopper and septum; an impervious disc may be provided between the septum and the tube interior.

Abstract: A head for an electric toothbrush includes a support member having a plurality of holes extending completely therethrough. A plurality of tufts of bristles each extends through one of the holes. A first brushing end of each tuft projects from a first side of the support member. Each tuft is prevented from being withdrawn from its hole when a tensile force is applied to the first end of each tuft along a long axis of the tuft. A resilient cushion is positioned adjacent a second side of the support member such that a second end of each tuft can contact the cushion. When a compressive force is applied to the first end of each tuft along the long axis of each tuft, each tuft can move in its hole in a first direction into the cushion. When the compressive force is removed the cushion causes each tuft to move in its hole in a second direction substantially opposite the first direction.
