Abstract: Aspects include a toothbrush and related methods of brushing teeth. In some cases, a toothbrush includes: a head including an approximately dumbbell-shaped core and a set of brushing portions extending from the approximately dumbbell-shaped core, the set of brushing portions including an upper brushing portion and a lower brushing portion, wherein the upper brushing portion and the lower brushing portion are oriented and spaced apart relative to one another to enable a provider to brush upper teeth and lower teeth of another person without removing the head from the mouth of the other person, and a handle coupled with the head, the handle including at least one longitudinal portion positioned relative to the head such that a hand of the provider is oriented at a distinct angle from the head while brushing the teeth of the other person and holding the at least one longitudinal portion.

Abstract: A wheelchair is provided. First supports for supporting a user of the wheelchair are unevenly disposed to form a perimeter, and second supports for supporting the user of the wheelchair are unevenly disposed at least partially within the perimeter of the first supports. The first supports support the user when the first supports are in a raised position and the second supports are in a lowered position. The second supports support the user when the second supports are in a raised position and the first supports are in a lowered position. A alternation of supporting the user with the first supports or the second supports facilitates reduction of pressure sores of the user. In various embodiments, multiple groups of supports are used, the supports contour to a user's anatomy and/or the supports are pneumatic.

Abstract: A toothbrush head and a method for brushing teeth. The toothbrush head includes a first brushing portion, and a second brushing portion. A first orientation of the toothbrush head includes the first brushing portion contacting an inside of at least one upper tooth and the second brushing portion contacting an outside of at least one lower tooth. A second orientation of the toothbrush head includes the first brushing portion contacting an inside of at least one lower tooth and the second brushing portion contacting an outside of at least one upper tooth. The method includes steps as follows: a) contacting, with a toothbrush head, an inside of at least one upper tooth concurrently with an outside of at least one lower tooth; and b) contacting, with the toothbrush head, an inside of at least one lower tooth concurrently an outside of at least one upper tooth.

Abstract: A wheelchair is provided. The wheelchair includes supports for supporting a user. The supports are configured to reduce or prevent ischemia or pressure sores of the user. In another aspect, a system of supports for supporting a user is presented. A group of the supports is arranged along the perimeter of the shape. At least some of the group of the supports have different vertical positions. In another aspect, the supports are arranged as a repeating pattern of shapes, the individual supports being peripherally disposed along perimeters of the shapes. The repeating pattern of shapes includes a first shape overlapping with a second shape, and some of the individual supports are disposed along perimeters of both the first and second shapes.
