Abstract: A lab-on-a-cartridge (LOAC) handheld assay device including an integrated test cartridge, a carbon nanotube electrode sensor, and a reagent dispenser for dispensing a liquid reagent into the test cartridge. The test cartridge includes a syringe plunger for drawing a test fluid into a test cavity, a bottom wall with a reagent inlet port, and a vibration adaptor for mixing. The reagent input port is attached with a slit valve for engaging with a slit spout of the reagent dispenser as a needleless dispensing system. Carbon nanotube sensors of different three-electrode configurations are provided for testing a volume of test fluid to increase the electrochemical reaction sensitivity. The assay device can be used with a CNT three-electrode sensor for saliva testing for determining glucose concentration.

Abstract: A pump toothbrush having a toothpaste tube to dispense dentifrice material to top of bristle head is disclosed. The pump toothbrush has a pump head with a resilient button to create an internal vacuum force to draw the dentifrice material from the toothpaste tube. The toothpaste tube is supported by width-limiting fingers to prevent total collapsing of sidewalls resulting in blocking of its flow channel. A self-closing spout is used for preventing backflow. For a manual pump toothbrush the toothpaste tube has an oval-shaped shoulder for mating with the oval-shaped shoulder of a detachable handle for fastening the toothpaste tube by threads. For an electrical pump toothbrush, a detachable endcap connector is used for swinging out the toothpaste tube from its handle for replacement. A sonic vibration model uses rubber molding to minimize vibration on the handle. A dual-rotary model has two rotary bristle elements engaged by gear teeth.

Abstract: A shaving applicator device provided with a shaving lubricant dispenser and an applicator head for applying lubricant directly on skin without hand touching the lubricant. The applicator head consists of a flow channel shaft, a roller having two end wheels and a rubber sleeve having self-closing slits. Under a pumping pressure, the lubricant emerges from the slits to spread on the roller surface. Gliding the roller on skin surface can spread the lubricant on the skin evenly with predetermined thickness. The dispenser may contain shaving foam, gel or liquid. For shaving liquid, foaming meshes are installed in the flow channel shaft for generating foam. Additionally, a combination shaver including a shaving lubricant dispenser, an applicator head and a razor unit is provided. In the combination shaver the razor unit and the applicator head are positioned in parallel back to back with a clearance.

Abstract: The invention relates generally to implantable drug delivery devices. Devices having a single drug chamber configuration, a divided drug chamber configuration and a compact dual-drug configuration are described. The devices have features to prevent clogging of the dispensing catheter and the creation of a local vacuum caused by the dispensing of the drug fluid. Also provided are features of a failsafe refilling process, automatic refill notification, and performance verification process. The divided drug chamber configuration enables frequent or continuous minute doses. A dual-drug chamber configuration uses self-locking refill containers to prevent mismatching between refill containers and drug chambers.

Abstract: A drug delivery device utilizing compressible fluid chambers for actuation is disclosed. The device includes a compressible dispensing chamber situated in a first compartment and a compressible filler-fluid chamber in flow communication with the first compartment. The compressible dispensing chamber is attached with a reciprocating plunger for dispensing the drug fluid. The drug chamber is refillable with a refill container that uses a compressible pouch containing the refill drug fluid. The refilling process is failsafe enabled by the insertion of the refill container needle only at the correct position to activate an internal contact switch. The compressible-wall configurations enable low dispensing forces without leakage of the drug fluid.

Abstract: Dentifrice dispensing electrical toothbrush comprising a driver-pump head with a dispensing platform, a replaceable brush unit and a handle having a battery and a cartridge containing dentifrice material. The replaceable brush unit includes a oscillatory brush element and a brush element having a circular or an elongated spout opening as well as a snap-on mounting bracket for fastening to the driver-pump head. The dispensing platform contains a flow channel and a self-sealing spout to prevent drying of the dentifrice material at the spout. The self-sealing spout opens and closes automatically during a pumping action. The brush element with a spout opening is detachably mounted over the spout fixed on the dispensing platform to allow for brush oscillation around the spout and receive the dentifrice material dispensed from the flow channel. Different drive mechanisms are used to impart rotary, lateral or longitudinal oscillation on a brush element in a brush unit.

Abstract: A sheet separating mechanism and a method of separating sheets that includes a retard surface carrier that causes a retard surface to apply an alternately higher and lower friction force against the edge of an underlying sheet. The alternation of the higher and lower friction force can be coupled to a vacuum sheet feeder. The retard surface can be translated to present a next portion of the retard surface to the edge of the next underlying sheet with the translation coupled to the vacuum sheet feeder.

Abstract: Pump toothbrush comprising a refillable cartridge containing dentifrice material, a pump head having an elastic compressible button, and a brush head having a spout opening attached with a slit valve.

Abstract: This is a mechanical oil dispenser for use in applying an oil to the surface (or two surfaces in a duplex mode) of printed media to improve its sheet-handling characteristics. This dispenser system has an oil-containing housing or tank with oil ports at the bottom of the tank. The ports are abutting a wick, this wick then disperses oil to an applicator roll which in turn applies oil to one or both surfaces of a printed media. The oil ports and oil flow are controlled by the profile of a cam and shaft in operative connection to said ports. Opening and closing of these oil ports are controlled by a cam shaft movement actuated by the rotation and stopping of the applicator roll.
