Abstract: A footbath has a base member defining a platform. A flexible continuous side wall extends from a proximal end region connected about a periphery of the base member to a distal end region. The side wall has a collapsed position and an extended position. The platform of the base member and the side wall cooperate to define a bath chamber for retaining water with the bath chamber sized to receive a body part. A retention member is supported by the base member to extend from the base member to the distal end region of the side wall to retain the side wall in the extended position.

Abstract: An electrostatic precipitator for an air purifier includes a first spiral strip having a continuous conductive electrode, a second spiral strip having a continuous conductive electrode and nested with the first strip, a plurality of combs. Each comb extends from an outer periphery of the precipitator to an intermediate region between the outer periphery and a center of the precipitator.

Abstract: A cuff for a blood pressure measuring system including a flexible elongate band having a first end and a second end and a sizing mechanism coupled to the band, wherein the sizing mechanism selectively permits relative movement between the first end and the second end of the band to expand and constrict a diameter of the band.
