Abstract: According to one broad aspect of one embodiment of the present invention, disclosed herein is a hand held oral irrigation device having a tip for dispensing fluids. In one example, an oral irrigation device includes a body portion, and a reservoir for storing fluids, wherein the body and/or the reservoir define a first major diameter at a lower end of the oral irrigation device, and define a second major diameter at an upper end of the oral irrigation device, the first major diameter being larger than the second major diameter. In this example, by providing such a geometry for the device, a user can grasp the device with one hand about the second major diameter during use. In another example, the body includes a pump for pumping fluids from the reservoir to the tip, wherein the pump includes an inlet valve and an outlet valve, the inlet valve including a reed valve made of flexible fabric material. The outlet valve may also include a reed valve made of flexible fabric material.

Abstract: An interproximal flossing device including a link member that isolates lateral from vertical rotational movement to transfer only translatory arcuate movement. This is done by the combination of a hinge and pivot structure. A tip attachment structure is also included for secure placement of the tip on the link member, and allows easy removal and replacement. A tip member removal structure is also included to allow for easy removal of the tip member from the link member.

Abstract: A shower head providing an improved pause mode that restricts the amount of water emanating from the head. The shower head includes a first and second outlet nozzle, a valve body operative to be in fluid communication with a shower pipe, the valve body having first and second flow channels in fluid communication with the shower pipe, each of which is also in fluid communication with one of the outlet nozzles. The first and second flow channels have different cross-sectional areas. In another embodiment, the valve body further includes a valve center in fluid communication between the first flow channel and the shower pipe, and is also in fluid communication between the second flow channel and the shower pipe. The valve body further defines a first hole in fluid communication with the first flow channel and the valve center, and a second hole in fluid communication with the second flow channel and the valve center, with the second hole having a smaller cross-sectional area than that of the first hole.

Abstract: An improved flossing device for cleaning between one's teeth is provided. The flossing device comprises a motor with a rotation drive shaft, a link member, and a motion translator. The link member has a first end and a second end, the first end adapted to receive a removable floss tip member. The motion translator is configured to transfer rotational motion of the drive shaft to the second end of the link member in the form of axial motion. In alternate embodiments, the motion translator transfers at least two types of motion from the group of vibrating, rotating, and axial motion to the second end of the link member.
